A roadway self-control dust removal system and method

Abstract

The invention belongs to the field of roadway dust removal, and relates to a roadway self-control dust removal system and method. It includes a press-in air cylinder and a dust collector arranged in the roadway. The dust collector includes a silencer section, a fan, a filter section and an exhaust section. The silencer section of the dust collector faces the dust, and the end of the exhaust section at the other end is a closed end; An air control device communicating with the interior of the dust collector is fixedly installed on the side wall of the exhaust section. The present invention changes the current situation that the traditional dust remover has no dust control device and cannot completely suck the dust-laden airflow in the roadway into the dust remover for dust extraction and purification. Control dust in the roadway to prevent the dust-laden airflow from spreading to the downwind side. It improves the dust extraction effect of the dust collector on the dust-laden airflow in the roadway, and prevents the dust-laden airflow from spreading to the rear end of the dust collector; at the same time, it also reduces the investment in the eddy current dust control device in the long-pump and short-pressure roadway, saving costs.

Description

technical field [0001] The invention belongs to the field of roadway dust removal, and relates to a roadway automatic control dust removal system and method. Background technique [0002] Long pressure and short extraction is one of the most widely used ventilation and dust removal technologies in roadways at present. The fresh air flow is sent to the working surface by the press-in local fan through the air duct, and the dust-containing dirty air flows through the suction port of the air duct and enters the dust collector for purification treatment, and the purified air is discharged to the roadway. [0003] The wet and dry dust collectors currently used in the roadway discharge the purified airflow directly to the rear end of the dust collector, which cannot play the role of dust control. [0004] At present, the dust collector in the long-pressure short extraction process cannot completely suck the dust generated head-on into the dust collector for purification, and part...

[0003] The wet and dry dust collectors currently used in the roadway discharge the purified air directly to the rear end of the dust collector, which cannot play the role of dust control

[0004] At present, the dust collector in the long pressure and short pumping process cannot completely pump the dust generated head-on into the dust collector for purification, and a part of the dust-laden airflow will diffuse to the rear end of the dust collector, resulting in the dust collector being too efficient even if the dust removal efficiency is high. The dust in the roadway cannot be reduced to an ideal state;

[0005] Aiming at the problem that the dust collector cannot completely draw in the dust-laden airflow, one of the current solutions is to connect a vortex dust control device to the air supply duct to form a vortex at the rear of the dust collector and control the dust-laden airflow in the dust collector. The front end prevents it from spreading to the rear end of the dust collector, but this method needs to add a vortex dust control device at the air supply end, which increases the cost and reduces the head-on air volume, which is not conducive to production safety; Add a press-in fan and vortex dust control device to the position to achieve the same effect as the above method, but this method will increase the investment of a press-in fan and vortex dust control device, and the cost will increase
