Dry explosion-proof dust collector is a kind of environmental protection equipment used in industrial production, its main function is to filter and clean the dust and waste gas generated in the production process, so as to prevent their harm and threat to the environment and the human body. Dry explosion-proof dust collector is an important means to prevent explosion, with explosion-proof, fireproof, anti-static, low energy consumption and other characteristics, is widely used in metallurgy, building materials, chemical industry, mining, electric power and other industries. In this paper, the composition, working principle, application field and development prospect of dry explosion-proof dust collector are introduced in detail.

1. Composition and structure of dry explosion-proof dust collector

1. Main structure

The main structure of dry explosion-proof dust collector is generally composed of air inlet, air outlet, box, access door, ash bucket, etc. The outside of the box is covered with insulation materials, and the inside of the box is equipped with dust collector core (or filter barrel), vibrator, compressed air system, etc.

2. Dust collector core (or filter cartridge)

Dust collector core (or filter cartridge) is a key part of material separation and capture, and its performance directly affects the filtration effect and durability. Commonly used dust collector core materials are polyester fiber, carbon fiber, glass fiber, electrospinning filter paper, fiber felt and so on.

3. Vibrator

The vibrator is used to clean the attachment on the dust collector core, and its vibration effect can make the dust fall from the dust collector core, so as to maintain the filtration efficiency.

4. Compressed air system

The compressed air system is an important part of the dry explosion-proof dust collector, which provides the power source for cleaning the dust collector core and makes the vibrator work normally. Its air pressure is generally 0.5-0.8MPa.

Two, dry explosion-proof dust collector working principle

Dry explosion-proof dust collector mainly uses the function of filter materials to filter the dust containing gas through the dust collector core (or filter cartridge), so as to achieve the purpose of purifying the waste gas. It works as follows:

1. The dust-containing gas enters the dust collector from the air inlet, and is filtered by the dust collector core (or filter barrel), the larger particles are separated and captured, and the clean gas is discharged through the air outlet.

2. When the dust accumulates on the dust collector core (or filter cartridge) to a certain extent, the vibrator begins to work, and the dust falls from the dust collector core into the ash hopper through the vibration effect.

3. When the dust in the ash hopper reaches a certain level, open the access door for cleaning.

Third, the application field of dry explosion-proof dust collector

The application field of dry explosion-proof dust collector is very wide, mainly suitable for the following industries:

1. Metallurgical industry: high-temperature flue gas and chemically corroded steam in the metallurgical industry will form fine solid particles in the line, the equipment can separate and remove the soot in these flue gases, protecting the environment and the safety of workers.

2. Building materials industry: building materials industry furnace emissions contain silica, calcium oxide, alumina and other components, easy to pollute the surrounding environment, the use of this equipment can completely absorb these exhaust gases, and the environment is treated and protected.

3. Chemical industry: the exhaust gas produced in the chemical industry, such as smoke, dust, odor, etc., causes great harm to the environment, and the use of dry explosion-proof dust collector can completely remove noise, odor, dust, etc., making the factory environment safer.

4. Mining industry: The mining industry produces magnesite, silica, iron ore and other dust more, the use of dry explosion-proof dust collector can effectively deal with industrial hard dust, to ensure a clean production environment.

5. Power industry: The power industry mainly involves combustion power generation, nuclear reactors, boilers and thermal energy equipment and other fields, it produces huge waste gas, complex composition, the use of such equipment can effectively collect waste gas dust, sulfate and sulfur dioxide.

Fourth, the development prospect of dry explosion-proof dust collector

With the improvement of social awareness of environmental protection, dry explosion-proof dust collectors will play a more important role in environmental protection equipment. In the future, with the continuous development of science and technology, the structure and technology of dry explosion-proof dust collector will be more perfect and optimized, and its work efficiency, cleaning effect and automation level will be continuously improved. At present, the domestic dry explosion-proof dust collector market is in a period of rapid development, and the market demand will be more and more large, which also brings huge business opportunities and development opportunities for the industry.

In short, the dry explosion-proof dust collector is an important environmental protection equipment, which can effectively purify the exhaust gas in the atmosphere and reduce the pollution to the environment. It has been widely used in industrial production and is of great significance for protecting the environment and human health and safety.
