Design principles for explosion-proof cabins
The design of explosion-proof cabins should follow the following principles:
1. Safety: The design of explosion-proof cabins should first ensure their explosion-proof performance, prevent sparks from being generated in hazardous environments, and thus prevent explosions.
2. Practicality: The design of explosion-proof cabins should consider their practicality, ease of operation and maintenance, while ensuring their electrical performance and ensuring the normal operation of electrical equipment.
3. Aesthetics: The design of explosion-proof cabins should pay attention to their aesthetics, so that they can meet functional requirements while also providing people with aesthetic enjoyment.
Design method of explosion-proof cabin
The design of explosion-proof cabins can be achieved through the following methods:
1. Structural design: The structural design of explosion-proof cabins should take into account their explosion-proof performance. For example, the destructive power of explosions can be reduced by adding isolation belts, installing explosion-proof windows, and other methods. At the same time, practicality should also be considered, for example, operating platforms, ventilation openings, etc. can be set up to facilitate operation and maintenance.
2. Material selection: Choosing high-quality materials can ensure the appearance quality and durability of the explosion-proof cabin. For example, materials such as stainless steel or aluminum alloy can be chosen.
3. Color matching: Through reasonable color matching, the explosion-proof cabin can look more beautiful. For example, you can choose colors that are in harmony with the surrounding environment, or choose some fashionable color schemes.
4. Decorative elements: By adding some decorative elements such as logos, icons, etc., the explosion-proof cabin can be made more distinctive.
Suggestions for choosing explosion-proof cabins
When choosing an explosion-proof cabin, the following aspects should be considered comprehensively:
1. Understand the requirements: Choose the appropriate type, function, and explosion-proof level of explosion-proof cabin based on your actual needs.
2. Focus on quality: try to choose as much as possiblegoodThe explosion-proof cabin ensures product quality and performance.
3. Price comparison: When purchasing from different suppliers, it is necessary to first compare prices and choose products with higher cost-effectiveness.

Explosion proof cabin size

According to user needs, it is generally manufactured with dimensions of 3000mm (length) x 3000mm (width) x 3000mm (height) outside the cabin

The cabin belongs to non-standard products, and its size can be determined based on the number, type, system complexity, and operation and maintenance space of the analyzers, with appropriate room for adjustment. Due to the limitations of long-distance transportation conditions, its external dimensions are generally as follows:

lengthThe outdoor main body of 2.5-6.5m should not exceed 6.5m in length due to standard steel sizing, lifting, and transportation structural strength issues. If the length of a single analysis cabin is 6.5m, a combination structure can be used, which can be made separately and transported to the site before being combined into one, or two analysis cabins can be used for implementation.

Width:The outdoor main body should be 2.5m, and the maximum width should not exceed 3.0m (limited by the width of road transportation, the width should not exceed 3.0m)

Height:Outdoor main body 2.5-3.0m (limited by height when passing through overpasses and tunnels), indoor net height 2.2-2.8m

Structure and material requirements for explosion-proof cabin machine city

⑴ Skeleton, base, and roof
The skeleton, base, and roof of the analysis cabin are made of metal components welded with steel sections, and should have sufficient strength and rigidity to ensure that the analysis cabin does not deform during loading, lifting, translation, and transportation.
The main frame of the base should use 12 # to 20 # channel steel, and two 10 # to 12 # channel steel or I-beams should be used as support beams below the floor keel. The main frame, floor keel, and support beams should be welded together to ensure that the floor does not vibrate when maintenance personnel walk indoors.
The roof frame and main beam should be made of 10 # to 12 # channel steel, and 8 # to 10 # channel steel should be used as the main beam and roof keel support in the width direction, all of which should be welded to prevent distortion and deformation. The roof should have a certain inclination, with a slope of at least 4%, and can be in the shape of an A or a sloping structure. It is not allowed to use a flat top to prevent rainwater accumulation.
⑵ Interior and exterior walls, as well as interior and exterior roof panels
The exterior wall panel should be made of 1.5mm #~2.0mm steel plate, and can be assembled with a π - shaped plate structure to form the exterior wall. If the welding process can be guaranteed, ribbed galvanized sheet welding structure can also be used to form the exterior wall. The exterior wall panels with a π - shaped panel assembly structure should use stainless steel plates (304SS, stainless steel brushed film coated plates are recommended), or galvanized steel plates. When using galvanized steel plates, surface spraying treatment must be carried out first, and the spraying color should be white or gray.
The interior wall panels and ceilings should be made of 1.5mm #~2.0mm steel plates, and the electrical cabin materials should be galvanized steel plates or cold-rolled steel plates. Stainless steel plates can also be used according to user requirements. When using galvanized steel plates or cold-rolled plates, surface coating treatment must be carried out first. The coating color is white glossy paint for the ceiling and white matte paint for the interior wall panels.
The roof panel must first undergo effective rainproof design, which can be achieved through the use of assembled rainproof designs with buckle structures or flat welded rainproof designs. The material is made of 1.5mm #~2.0mm stainless steel plate to ensure the long-term corrosion resistance of the roof surface. The outer roof has a load-bearing capacity of ≥ 250kg/m2 (the weight of two people) and does not deform.

⑶ Insulation layer
Fire retardant insulation materials (such as mineral wool) are filled between the inner and outer walls and the inner and outer roofs. The thickness of the insulation layer is generally 70-75mm (3 minutes), and it should be thickened to 80-85mm in severe cold or hot areas.
⑷ Floor
The floor should be made of anti slip metal plate, preferably made of 4-6mm steel plate. The material can be patterned stainless steel plate, patterned galvanized steel plate or hot-rolled steel plate according to user requirements. Galvanized steel plate or hot-rolled steel plate must be sprayed on the surface first, and the spraying color is generally gray. If necessary, a layer of anti-static plastic plate can be added.
Avoid dead corners and grooves inside the cabin that may accumulate gas. Suitable manual or automatic exhaust holes should be opened at high and low points of the cabin to prevent gas accumulation. The sample pretreatment unit, carrier gas cylinder, standard gas cylinder, and laboratory manual analysis sampling point should be located outside the cabin.

explosion-proofPower distribution in the cabin
The common equipment such as lighting, ventilation fans, air conditioning, and maintenance sockets in the analysis cabin are powered by industrial power supply. The analyzer system, installation detection alarm, and interlocking system are powered by UPS power supply.
