Coal mine underground blasting operation space instantaneous smoke dust rapid elimination device and use method

Abstract

The invention provides a coal mine underground blasting operation space instantaneous smoke dust rapid elimination device and a use method. The device comprises an underground compressed air pipeline,a negative pressure ejection device, a multistage negative pressure dust collection device and a high pressure wet spraying device. Firstly, high pressure gas enters the negative pressure ejection device, and a high negative pressure environment is formed in a negative pressure ejection cavity; the negative-pressure power is used for sucking smoke and dust through the multistage negative-pressuredust sucking device, and separation is implemented; and the dedusted flue gas and high-pressure gas are mixed and enter the high-pressure wet spraying device, toxic and harmful flue gas is absorbed by an organic active agent, moisture formed by combining clean gas and the organic active agent is sprayed to an underground blasting operation space, and further dedusting is implemented. The device is small in size, convenient to move, easy to operate, capable of achieving industrial production and high in field practicability. The device has a multistage linkage smoke dust eliminating function of absorbing dust at negative pressure, dissolving smoke with an organic active agent and humidifying and settling dust at high pressure, the efficiency is high, the effect is good, and low-cost and high-speed effective treatment is achieved.

Description

technical field [0001] The invention belongs to the technical field of fume and dust treatment, and in particular relates to a device for rapidly eliminating instantaneous fume and dust in an underground blasting operation space of a coal mine and a method for using the same. Background technique [0002] Underground mining in coal mines inevitably requires the use of explosives or other blasting materials. When blasting is carried out, a large amount of toxic and harmful smoke and dust, such as carbon monoxide, nitrogen dioxide, nitrogen trioxide, sulfur dioxide, hydrogen sulfide, ammonia and respiratory Dust, its concentration is far greater than the concentration of smoke and dust generated by mechanical working surfaces. High concentrations of smoke and dust will not only threaten the safety of mine production, but also induce various occupational diseases such as lung, cardiovascular and brain that endanger the health of miners. As of the end of 2018, a total of 975,00...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a device and method for quickly eliminating instantaneous smoke and dust in the blasting operation space of a coal mine, so as to overcome the downdraft air pollution caused by the use of the ventilation system to control the toxic and harmful smoke in the above-mentioned prior art and the repeated breathing of smoke by the staff. The secondary hazards of air, and the use of high-pressure water pump spray dust suppression and negative pressure system to capture dust and other technologies have secondary dust generation, complicated operation of electromechanical equipment, and dangerous electricity use.
