Explosion-proof According to the requirements of our country, it is not just as simple as isolating the inside and outside, just check the national explosion-proof standards.

The explosion-proof of foreign natural gas compressor control cabinet is simple, and the bottom of the cabinet body has a strong air intake, and the top has a strong exhaust air.

The gap is too big, our national standards are too rigid, and of course the security is also high.

First of all, in order to understand the explosion-proof principle of explosion-proof cabinets, it is necessary to understand from the definition of **. **Refers to the process of energy being converted into energy from concentration and expansion in a short time and in a small space, with strong mechanical effects. It is a very rapid physical or chemical energy release process.

In this process, the matter in space releases energy at a very fast rate and converts it into mechanical energy, light, heat, and other forms of energy. Therefore, once out of control, the accident will have a huge devastating impact.

The most important feature is the sudden change in pressure between the system and the surrounding medium, which is the direct cause of the destruction. When the combustible gas reaches a certain concentration in the air, it will occur in case of open flame**. In daily industrial production, there are generally three situations:

When the combustible gas reaches a certain concentration, the fire and gas are satisfiedTherefore, the explosion-proof cabinet is mainly considered from the following aspects:1. Reduction of combustible concentrations:

Make the concentration of **substance below the **limit**, such as ventilation to prevent gas**, dust removal to prevent flour**. 2.Isolate the source of fire:

Prevent sparks, e.g. with arc extinguishing switches and explosion-proof motors. 3.Blocking the air:

Inert shielding gas is added.

Explosion-proof cabinets store all hazardous chemicals according to different colors. Explosion-proof cabinets come in four colors: yellow, red, blue, and white.

The chemicals stored in each color are different. Yellow indicates flammable liquids, red indicates flammable liquids, blue indicates weakly corrosive liquids, and white indicates strongly corrosive liquids. In this way, hazardous liquids can be effectively identified, deterred and isolated by using explosion-proof cabinets in different colors.

Prevent various chemicals from mixing together and eliminate fire hazards.

The explosion-proof distribution cabinet is an extraordinarily explosion-proof type, and its primary experience is to block the flammable substances from the ignition source to achieve the explosion-proof intention.

The explosion-proof distribution cabinet is welded by castings or steel plates, with high strength, more expensive than ordinary explosion-proof boxes, and is suitable for dangerous combustible gas places and places.

Its explosion-proof principle is mainly to adopt explosion-proof measures to isolate the ignition source of the medium, so as to achieve the purpose of explosion-proof electrical appliances;

There are generally the following three conditions for the occurrence of ** in daily industrial production: 1. Combustible gas reaches a certain concentration 2, meets fire 3, and satisfies the air.

Therefore, the prevention of gas in daily industrial production is mainly considered from the following aspects: 1. Reduce the concentration of combustibles: make the concentration of combustibles less than the limit, such as using ventilation to prevent gas and dust to prevent flour; 2. Isolate the fire source

Prevent sparks, such as using arc extinguishing switches, explosion-proof motors, anti-static clothing, installing flame arresting covers, controlling ignition sources, etc.; 3. Blocking air: such as adding inert shielding gas.

If the generation of ** must start from the three necessary conditions, and limit one of the necessary conditions, it will limit the generation of **. Explosion-proof cabinets start by isolating the source of fire and blocking the air. First of all, the explosion-proof cabinet is classified and placed by different colors, and the explosion-proof cabinet has four colors yellow, red, blue, and white, and the chemicals stored in each color are different.

Yellow for flammable liquids, red for flammable liquids, blue for weakly corrosive liquids, and white for strongly corrosive liquids. In this way, hazardous liquids can be effectively identified, sorted and isolated by using explosion-proof cabinets of different colors. Prevent items that are prone to various chemical reactions from mixing together, and eliminate the hidden dangers of the items themselves.

In addition, in terms of material and safe use, the explosion-proof cabinet adopts a double-layer structure, high-quality cold-rolled steel plate, phosphating treatment, epoxy resin painting, and high-temperature curing. The bottom is designed with an anti-leakage threshold to retain the leakage liquid. There is a 50mm high leak-proof tank at the bottom of the cabinet so that the liquid that accidentally flows out does not spill.

The laminate is made of galvanized laminate, surface phosphating treatment, epoxy resin painting, high temperature curing, and unique safety corner design. The height of the laminate can be adjusted every 60mm distance according to the 2mm thickness component, which is very flexible and convenient. The use of silicate has the functions of heat insulation, sound insulation and explosion-proof, and is used as an explosion-proof component of explosion-proof cabinets.

According to the latest measures for the management of hazardous chemicals that are easy to make explosives (national standards), the GA cabinet lock equipped with 3-point linkage type, equipped with two keys, the connection between the cabinet door and the cabinet body adopts a long row of hinge hinges, which can be opened and closed at 180 degrees, and the operation is quite convenient and safe. In this way, it can effectively isolate the external air and fire source, and achieve the effect of blocking and explosion-proof.

The principle of explosion-proof cabinet explosion-proof is to achieve fire and explosion prevention in industrial production and life from the above two points. Of course, in order to truly and completely cut off the hidden dangers of fire and safety, we also need to have a standardized operation concept and a vigilant safety awareness at all times, and eliminate potential safety hazards from the source of our thoughts.

In order to better distinguish the classification of chemicals, explosion-proof cabinets have 3 colors, namely yellow flammable chemical explosion-proof cabinets, red combustible chemical explosion-proof cabinets, and blue corrosive chemical storage cabinets. Explosion-proof cabinets, also known as fireproof safety cabinets, fireproof cabinets, and chemical safety cabinets, are used to standardize the safe storage of all kinds of hazardous chemicals; The national security department has special regulations that flammable and explosive hazardous chemicals should be stored in cabinets with special materials and special structures.

This kind of cabinet is called explosion-proof cabinet, also known as fire safety cabinet and chemical cabinet. Alcohol, white oil, Tianna water, gasoline, paint, these volatile and flammable substances are often used in the factory workshop, so a little carelessness in storage and placement may lead to disasters and serious losses to the company and the surrounding enterprise environment, so explosion-proof safety cabinets are indispensable products in the factory. The national standard stipulates that flammable, explosive and corrosive chemicals should be stored in special fireproof and explosion-proof safety cabinets, and the color of the cabinets stored in different chemicals is also the same, so that the dangerous nature of chemicals can be distinguished by color and standardized management.

Common explosion-proof safety cabinet products generally have three colors: the yellow cabinet is generally used to store flammable liquids: such as alcohol, glue, gasoline, kerosene, **, nitrocellulose, Tianna water; The red cabinet is generally used to store flammable liquids

Such as hydrogen, carbon monoxide, propane, ethylene, etc.; The blue cabinet is generally used to store weakly corrosive liquids, such as hydrochloric acid.

If the explosion-proof cabinet is used to store hazardous chemicals, it can also be called a fireproof cabinet, and its main function is fireproof.

Explosion-proof cabinet is an important member of laboratory furniture, explosion-proof cabinet is mainly used in hospitals, enterprises, industries, laboratories, schools and other places, is an important safety protection equipment to protect experimental reagents and experimental personnel. There are three main colors of explosion-proof cabinets: red, yellow and blue, and different colors represent different use classifications. Generally, yellow explosion-proof cabinets are used to store flammable liquids.

Red explosion-proof cabinet: used to store flammable liquids; Blue explosion-proof cabinet: used to store weakly corrosive liquids;

When the situation is to keep important items, that is, to prevent the violent opening of the cabinet.

Explosion-proof cabinets safely store hazardous chemicals to reduce the risk of fire while protecting staff and equipment;

The function of explosion-proof cabinets is to safely store hazardous chemicals, reduce the occurrence of fire accidents, and protect the safety of people and equipment. Organize, organize, separate all kinds of dangerous liquids, store solvents nearby to improve your work efficiency, and three-point linkage lock to enhance security.

In order to better distinguish the classification of chemicals, explosion-proof cabinets have 3 colors, namely yellow flammable chemical explosion-proof cabinets, red combustible chemical explosion-proof cabinets, and blue corrosive chemical storage cabinets.

Explosion-proof cabinet is a kind of safety equipment used to store flammable and explosive materials, and in order to ensure the safety of personnel and the environment, explosion-proof cabinets need to be controlled. The following are some control measures for explosion-proof cabinets:

Periodic Inspection: Regular inspection and maintenance of explosion-proof cabinets to ensure their proper working and use. The inspection content includes the environment, ventilation, equipment status and so on inside the explosion-proof cabinet.

Strict access management: A strict management system should be set up for the import and export of explosion-proof cabinets, including entry and exit records, authorization management, personnel restrictions, etc.

Labeling: The exterior of the explosion-proof cabinet should be marked with obvious signs, indicating the name and characteristics of the stored items, and should meet the standards stipulated by the state.

Good ventilation facilities: The explosion-proof cabinet should be equipped with good ventilation facilities to ensure the circulation of air flow in the cabinet and avoid the danger caused by gas accumulation.

Regular cleaning: Regularly clean the explosion-proof cabinet to remove dust and debris, etc., and keep the cabinet clean and tidy.

Waste disposal: Waste or invalid items should be disposed of in accordance with national regulations, and should not be thrown away or mixed with other items.

Why use chemical fire safety cabinets?

First, prevent fires and control spills;

second, to protect human life, property and the environment;

Third, reduce costs and improve work efficiency, because of the small size, it can be placed in the workplace to store flammable and explosive materials, without frequent travel to and from the dangerous goods storage room, saving time and effort;

Fourth, the effective management of various dangerous goods, different colors of safety cabinets have different functions, and the chemicals that can be stored are also different, which are stored in different categories, which are clear and easy to manage at a glance;

7.The inside and outside of the explosion-proof cabinet is phosphoric acid passivated and electrostatically sprayed with epoxy resin to maintain a high finish and minimize the effects of corrosion and moisture and UV rays.

Many people who have not been in contact with explosion-proof cabinets may have questions, what is the explosion-proof cabinet and what is it used for? Let's first understand that at present, in many factories (such as printing plants), chemical liquids will be used in the production process, such as Tianna water, wiping machine water, washing water, ethanol, etc. Chemical liquids such as these are flammable or flammable, which means that these chemicals have a very low ignition point and may spontaneously ignite at a certain temperature.

The storage of these chemicals is particularly critical, as unreasonable storage or non-standard management can easily cause leakage, which can lead to fire. In recent years, fire incidents have occurred from time to time, and according to reliable data, there were 352 fires in Shenzhen from January to March in 2013 alone. The fire house seriously endangers the safety of people's lives and property, and for this reason, the Shenzhen Municipal Safety Supervision and Management Commission at all levels also attaches great importance to fire safety.

There are many factors that lead to fires, but many of them are not good fire prevention measures and other factors, imagine the improvement of various safety and fire prevention facilities, whether the probability of fire occurrence should be greatly reduced? The answer is yes. Today, I will introduce you to an industrial fire safety equipment, which can safely store Tianna water, wiping machine water, washing water, white electric oil, alcohol, paint, placing gasoline, and a variety of dangerous chemicals, it is an explosion-proof cabinet, also known as a fireproof cabinet, a safety cabinet, a chemical cabinet, a flammable and combustible liquid storage cabinet, an oil drum cabinet, and a special cabinet for hazardous chemicals.

Flammable and combustible chemicals are stored in explosion-proof cabinets, and the safety will be greatly improved.
