Which method of mine dust control is the most effective

Mine dust control generally uses pulse bag dust collector to transfer crushing and screening belts for dust control.

Hello, glad to answer for you. What should be done about dust control: Ceramic enterprises belong to high-pollution, high-energy-consuming industries, and their production processes pollute the environment relatively large, especially air pollution.

With the increase of people's attention to air pollution, the dust pollution problem of ceramic enterprises has become one of the important problems in environmental protection. Therefore, it is necessary for relevant staff to carefully analyze the dust pollution sources at the production site of ceramic enterprises and do a good job in the corresponding treatment. 1 Analysis of dust pollution sources Raw material silos and coal bunkers Because of the large number of materials stored and the large amount of use, the warehouse area is relatively large.

When the material enters the site, the dump truck can be used to dump the material to the silos, but when unloading, the air will be instantly filled with a high concentration of dust, which will drift to the surrounding area with the air flow to cause pollution. At the same time, in the transportation operation, the material dropped by the forklift is crushed by the wheel, which will produce dust; When the forklift puts the material into the feeder, it is also affected by the recoil of the drop and the air flow of the hopper, which also generates a lot of dust. Up to now, there are no ceramic enterprises to carry out corresponding governance work for this problem.

Raw material workshop uses belts to convey powder from the first floor to the third floor, and due to the limitation of belt length and climbing slope, it is necessary to use multi-section belts to complete relay conveying. During this process, both belt vibrations and drops in the belt adapter point generate fugitive dust. In this regard, most enterprises only use the guide trough to reduce the drop to achieve the purpose of dust control.

The large drop from the belt to the individual tanks, combined with the backflush air flow of the tanks, can generate fugitive dust. The dust that permeates the workshop is fine-grained mud dust (particle size of 5 20 m), and the dust concentration in the workshop will increase without stopping, and it will drift to the surrounding workshops with the air flow. In the process of conveying the powder from each pipeline to the distribution car, the distribution port, the mold movement, the press suppressing the air flow and overflow, the contact point of the brick platform, the ash sweeper, etc., will produce dust, and the non-stop production will lead to continuous dust.

Extended information: 1. The coal seam is pre-injected with water to prevent dust. In the 50s of the last century, it was popularized and applied in coal mines.

The dust reduction rate can be 60% to 90%. A variety of coal seam water injection technologies have been studied in China. 2. Water seal blasting and dust reduction.

At present, the gel water cannon mud has a good dust and smoke reduction effect, and the comparative test shows that the dust reduction rate of total dust is improved. 3. Closed dust extraction. Mainly for factories and mines with large dust production, the dust source is closed with a closed hood, and the dust reduction rate is as high as 95%, but there are shortcomings such as long installation time, large floor area, and easy wear and tear of the machine.

4. Optimization of coal mining process. When the shearer is mining, eliminating the re-crushing of coal is an effective way to reduce the dust content of the fully mechanized mining face, and the important measure is to improve the structure of the shearer or optimize the cutting process. There are many ways to control the spread of dust, using adsorption, suppression, isolation, and collection.

It depends on what kind of industry and scenario is handling dust.

If the dust control is carried out in the production workshop, the plan will be designed according to the type of dust in the industry and the scene situation of the workshop to match the appropriate equipment.

meansIn general, dust and dust-containing gases are collected at the front end, and the dust and dust-containing gases are separated and processed through the pipeline into the dust removal equipment (bag filter or other types of dust removal equipment are used separately or in combination) to separate and treat the dust and dust-containing gases, and finally meet the standard discharge.

The main contents include comprehensive dust-proof technical measures for key dust-producing sites, explosion-proof technical measures for coal dust, mine dust monitoring technology and coal mine dust-proof management.

Mine Dust Control Technology

This paper systematically expounds the basic knowledge of mine dust, and comprehensively introduces the scientific research achievements and practical technologies of mine dust prevention and control at home and abroad from both theoretical and practical aspects.

Eliminating or mitigating dust hazards with engineering and technical measures is the prevention of pneumoconiosis.

fundamental measures.

1. Reforming the process and innovating production equipment are the main ways to eliminate dust hazards, such as remote control, computer control, compartment monitoring and other measures to avoid workers from being exposed to dust; Wind transportation, negative pressure sand suction and other measures are used to reduce dust overflow; Replace quartz sand with limestone with low quartz content and low harm.

as a casting material.

2. Wet operation is a relatively economical, simple and practical anti-dust and dust reduction measures, such as the use of wet grinding quartz, refractory raw materials, mine wet drilling, underground transportation spray sprinkling, coal seam high-pressure water injection, etc.

3. For places where wet operation cannot be adopted, the method of closed ventilation shall be adopted. For example, the combination of closed dust source and local exhaust is used to prevent dust overflow. The dusty air extracted is passed through the dust removal device.

It is discharged into the atmosphere after treatment.

What are the dust removal equipment that has a good birth effect, this you can buy some good paper from uh, the quality is.

So which shooter is really welcome to be born with a better effect of vegetarian powder? It's all good, it's good, and it's better to give you more power.

It is better to use pulsed electrostatic precipitator for general mine dust removal equipment, and the filtration effect is good.

Are you looking to buy a machine for dust collection equipment, right? I think it's better to buy a big brand, so it will take a little longer.

Well, if the sound effect of the dust removal equipment is better, I feel that you can buy some pothos and raise it in the house, and you can dust it all at once, and the effect is very good.

I have storage equipment which junior high school works well, anyway, you go to that shop around and choose the one that works best, and then come and buy it.

Mining equipment, he is better at this, if they talk to you, or that is better.

Huang Yongcheng set it up, and I think Yang Zi's car works better.

It is better to use the dust removal equipment of Yixing furniture, which is actually out of love.

These storage devices are basically about that.

Mining dust equipment, it can choose which one is good according to your needs.

According to the actual working conditions of the mine processing production line, it generally needs to go through crushing, screening, grinding, transportation, aggregate and other processes, and each process, along with the fragmentation and movement of the ore, the fine particles will be gradually separated, which will produce more and more dust.

In view of the causes of mine dust and the nature of dust, the whole dust removal system adopts the dust production point to collect through the dust collection hood, enters the pulse bag dust collector by the pipeline, and discharges it into the atmosphere through the chimney after the purification of the dust removal bag. That is, a closed device or dust collection cover is set up at the feeding port, discharge port, upper part of the vibrating screen and the belt conveyor transfer point of the crusher or crusher, and a double-layer airtight cover should be set up at the receiving place of the transfer point. Cover the dust-generating equipment with a closed hood, or make a dust collection chamber to form a uniform negative pressure in the hood to avoid dust escape, or use an open suction hood to form a suction and capture airflow, control the exposed dust-carrying area within a narrow range, so that the dust-carrying airflow is sucked and pumped away, and is purified by the bag filter and discharged into the atmosphere through the exhaust cylinder (or chimney).

The dust removal efficiency of the mine pulse bag filter can reach more than that, and the ash cleaning capacity is strong, which can well solve the dust pollution problem of the mine production line.

Mining dust removal equipment, which dust removal effect is good? Even this effect is very good.

The types of dust emissions are generally divided into: organized emissions, fugitive emissions, the so-called fugitive emissions, that is, all the smoke and dust that leak through the chimney or exhaust system, productive dust and other harmful pollutants are called fugitive, and vice versa, they are called organized emissions.

As for the treatment method, it depends on what kind of dust, general metal dust, its proportion is large, can be naturally reduced, collected as general solid waste treatment.

If the rest of the dust is collected, a gas collection hood is set up at the polluting station and discharged to the roof through a special pipe, or a vacuum cleaner is purchased and collected at its post.

Industrial dust control: At present, most enterprises use bag dust collectors to collect. It's one of the most environmentally friendly practices of the moment. To put it simply, the air collection hood is installed above or on the side of the dust generation point, and the air with dust is directly adsorbed into the pipeline through the suction generated by the fan, and transported to the bag dust collector to be directly filtered out by the bag.

The dust falls into the hopper by blowing the dust through strong pulsation, and the clean air is discharged directly.

Industrial dust control methods generally use bag dust collectors or filter cartridge dust collectors

There are many classification methods for mineral dust, and at present, there are mainly the following classification methods for mineral dust in China's coal mines: (1) Classification according to the composition of mineral dust Coal dust: coal particles with a diameter of less than 1 mm.

Rock dust: rock particles with a diameter of less than 5 pm (2) Classified according to the content of free SiO2 in mineral dust Silica dust: The content of free SiO2 in mineral dust is more than 10%.

Non-silica dust: the free SiO2 content in mineral dust is 10% or less. (3) Classification according to the existence state of mineral dust Floating dust:

Mineral dust suspended in the mine air. Dust: Mineral dust deposited around the shaft, on supports, equipment, and materials.

4) Classification according to the point of view of hygiene Total dust: the sum of mineral dust of various particle sizes suspended in the mine air, formerly known as total dust.

It refers to mineral dust that can be inhaled through the nose and mouth during normal breathing. Non-respirable dust: dust that enters the body, but cannot enter the human alveolar area due to the interception and retention of the nasal, pharynx, tracheobronchi, and bronchioles.

Respirable dust: Dust that breathes into the alveolar area of the human body.

It is the dust that causes pneumoconiosis. The aerodynamic diameter of the respirable dust is below , and the efficiency of the aerodynamic diameter 5 is 50%. (5) According to the classification of mineral dust

It has the highest quality, and the first mineral dust can occur under certain conditions.

Non-sexual mineral dust: It has no mineral dust and will not occur under any conditions.

The types of minerals mainly include coal dust, stone dust, etc., for such dust prevention, the most important thing is that you bring protective equipment to prevent dust from being inhaled into the lungs.

Mineral dust respiratory diseases are mainly lung diseases caused by inhaling too much dust, usually with pneumoconiosis, which is more difficult.
