Air shower room, air shower design, design air shower room The air shower room has two forms: superior human shower room and cargo shower room. The selection of air shower room for human shower is generally based on 25 people. Generally, single air shower room is selected when the number of people is less than 25, double air shower room is selected when the number of people is more than 25 and less than 50, and so on. Key points and precautions of air shower design, how to design air shower more reasonably? The cargo shower is a device that cleans some goods. It has no base plate and its size is determined by the size of the trolley used for loading and unloading goods. This kind of equipment is easy to install and select materials at will, which is a future development trend.

In the TIMER display window on the left of the operation panel, "shower time, cycle time, operation status and various parameters" can be displayed. In the right Door area, the status of the doors on both sides is displayed in real time. When the "Close" light is on, the doors are closed. When the "Lock" light is on, the doors are locked.

Common fault editing 1. Power switch. Generally, there are four places in the air shower room where the power can be cut off

1. Power switch of outdoor cabinet for air shower;

2. Control panel of cabinet in air shower room;

3. On the outer boxes on both sides of the air shower room (the power switch here can prevent the power supply from being cut off in case of emergency and effectively protect our human body).

4. The 380V three-phase four wire power supply shall also be installed in place at the installation site of single and double hair shower rooms, and the power supply power shall be greater than that of single and double hair shower rooms.

5. The ground placed in the single and double blow shower rooms has reached the basic level, and the ground levelness tolerance is ± 3mm. Outline of air shower room and outline of recommended air shower room (1) The person in charge of air shower room shall regularly replace the primary filter material every quarter.

Control form

Fully automatic control means that the door body is photoelectric induction, and the whole operation is automatic.

The semi-automatic control means that the door is opened manually, and the air shower area automatically blows water.

Reference for air shower design data:

The automatic door of shower room has different brands and prices. For example, our company has been using imported automatic door devices such as Delos, etc. in the automatic door shower room. Generally, the production personnel of the shower room know that there are large and small boxes in the shower room, so for ordinary laymen, how should the large and small boxes in the shower room be configured.

This cargo air shower chamber uses 4 sets of primary and primary efficiency filters, 4 sets of 0.75KW low-noise high air pressure centrifugal fans, and the air shower time can be adjusted from 0 to 180 seconds at will. The efficiency of the high-efficiency filter should be ≥ 99.995% (sodium flame method) for dust with particle size ≥ 0.5um. The nozzle diameter is 38mm, and the total number is 39. Two sides and top sides are used for air blowing, and the air shower effect is better. The air velocity at the nozzle outlet is ≥ 20m/s.

Close the door of the shower room and start the fan of the shower room. Measure the indoor and outdoor pressure difference after 15 seconds. Repeat the measurement three times. 6 Leakage current shall be detected according to. The current value shall comply with the regulations. 7. The grounding resistance All the function switches of the air purification shower chamber to be tested shall be set to the "off" position, and the resistance between the grounding terminal and the accessible metal parts shall be measured with the grounding resistance meter, which shall meet the requirements.

1. The criteria for the structural layout of the air shower chamber are: frame beams are set between columns and between columns and shear walls, and cast-in-situ concrete hollow slabs are used as the slabs enclosed by frame beams.

2. The frame beam of the air shower room is generally a concealed beam, and the height of the concealed beam is the same as the thickness of the hollow slab.

3. The main structure of the air shower can be generally designed according to the current standard, and the concealed beam should be considered as wide flat beam.

4. Cast in situ concrete hollow slab is generally calculated as per one-way or two-way internal force.

In recent years, the information broadcast in the news is frequently about the production of the factory, for example; It is haze climate and PM2.5 that can kill people; Then there are questions about food. For example, the food consumption is in doubt, which is severe. According to the air shower manufacturer, from all perspectives, the air pollution, food consumption and output mainly come from the factory. We all know that a dust-free room is a very clean closed workshop. If you want to ensure that the production products are qualified, you must use purification equipment. The air shower room is a high-quality product of purification equipment. Through the air shower room, the number of qualified products in the production workshop has greatly increased to a level, thus reducing the cost of enterprises and defective products; Moreover, the air shower is affordable and has a long working life; Simple operation, i.e. power saving; The air must be used in front of the dust-free room for workers.

At present, some defective businesses in the market will confuse the stainless steel models. Generally, the model of the air shower is generally the SUS304 stainless steel model specially used for food. However, there are many manufacturers on the market who mainly promote 201 type stainless steel. 201 stainless steel is also called stainless steel, which is easy to rust in the air with salt. The important role of air shower room in GMP purification workshop in 2018 Under the strict GMP, pharmaceutical enterprises require the establishment of scientific aseptic production, process, operation and system, all possible and potential biological activity, dust, pyrogen pollution, to ensure the production of high quality, adequate health.

How to select air shower room

Selection of materials

1. Color steel sandwich panels are suitable for dry workshops. The length of the air shower room is determined according to the number of uses. The price is relatively low. (This is not used now)

2. Cold rolled steel plate is suitable for electronic industry, dairy industry, baking food, and the price is relatively moderate.

3. Stainless steel plate is suitable for food processing, aquatic product processing and export enterprises with high requirements, especially in coastal areas, where workshops are matched, and stainless steel can avoid equipment rust.

General structural requirements of air shower design room scheme:

1. The calculation of cast-in-situ hollow slab is a new type of structural system extended with the development of BDF technology and BDF thin-walled pipe data. When designing and calculating the air shower, the calculation of internal force reinforcement shall be stopped by referring to the calculation method of solid steel concrete floor or beamless floor. When calculating the reinforcement, the parallel pipe laying direction can be simplified as "I" section to stop the internal force reinforcement calculation. When the pipe laying direction is vertical, the internal force reinforcement calculation of the mid span slab section will stop, and the internal force reinforcement calculation of the slab section on the air shower column will stop.

2. Common structure requirements for air shower design

1) The concrete grade of air shower room shall be ≥ C20, and the plate thickness can be taken as:

2) Minimum reinforcement ratio of air shower 0.2%

3) The maximum reinforcement ratio of air shower room is 1.2%

4) Air shower room hollow rate 30% - 55% 5) Air shower room toilet floor fall is 80-360mm

6) The air shower shall conform to the structure of air shower plate with a span ≤ 15m (non prestressed) and ≤ 25m (prestressed).

The reasonable distribution of logistics is of great significance to the cleanliness of the air shower room. Whether people are showering before entering the clean room, and whether their clothes meet the cleanliness specifications, some personnel with special production processes and high requirements for cleanliness should also take a bath before entering the clean room; Whether the materials are replaced before entering the clean room, and whether the replaced materials conform to the clean room, etc.

If the number of people is more than 100 or even more, it will be necessary to choose a length of more than five or six meters or non-stop access to the air shower room, which can limit the guarantee of fast passage of personnel during work hours, and avoid high concentration and detention of personnel during peak hours, thus causing workers to wait for too long and causing restlessness.

For example, stainless steel materials should be more than 1.2mm thick according to the quality in the industry at present, but under the current situation, many manufacturers use 1.0, and even some non professional manufacturers in Shandong use 0.7-0.8mm stainless steel for production. Such thin stainless steel plate made of the air sprinkler chamber is easy to deform and other failures under the action of the door opening and closing force after slight collision.

Shower form

The single blow type side plate has a nozzle, which is suitable for factories with low requirements, such as food packaging or beverage processing, bucket water production, etc.

The double blow type has nozzles on both sides of the side plates, which is suitable for the entrance and exit of the clean room of the purification workshop staff in the electronic factory.

The three blowing type has nozzles on both sides and on the top, which is suitable for food processing, export processing enterprises, or industries with high requirements for high-precision instrument control.
