Abstract

The invention relates to the mining industry and m. used to dedust the air. The purpose of the invention is to increase the efficiency of air dedusting when changing the number of overloaded bulk material by automatically controlling the steam supply depending on the amount of dust ejected into the shelter and stabilizing the air velocity in the shelter. The shelter includes a housing 1 with an upper 6 and side walls, an estrus 2 for feeding bulk material, an aspiration pipe 5, and a steam line with steam nozzles 9 for supplying steam to the inside of the housing 1. The steam line has a regulating valve 8. The wall 6 is fully movable and interacting with the valve 8 by means of a hinge connection 7. Dusty airflow, passage through housing 1 towards nozzle 5, encounters a vapor cloud from the nozzle 9 Due to this, dust particles coagulate and spread onto the conveyor belt. The most complete sedimentation of dust particles is carried out with the help of wall 6. 1 sludge. 1 tab. with (L

The invention relates to the mining industry and can be used to dedust the air when overloading bulk materials during various technological processes.

The purpose of the invention is to increase the efficiency of air dedusting when changing the amount of overloaded bulk material: by automatically adjusting the steam supply depending on the amount of dusty air ejected into the shelter and stabilizing the air velocity in the shelter.

The drawing shows a diagram of the aspiration shelter.

The aspiration cover includes a housing 1 with side walls, a chute 2 for feeding bulk material 3 onto a conveyor belt 4, an aspiration pipe 5, an upper movable wall 6 of housing 1 connected by a hinge connection 7 to a valve 8 that regulates the flow of steam to nozzles 9. The mobility of the upper wall 6 is ensured by the fact that it is attached around the perimeter to the side walls of the housing 1 with the help of a pleated rubberized fabric. In the uppermost wall 6, holes are made, sealed by a sealant, through which a steam line leading to the nozzles 9 enters the internal volume of the shelter.

Aspiration shelter works as follows.

The dusty air enters the housing 1 along with the bulk material 3 through the leak 2. At the moment of material impact on the tape 4, there is a sharp increase in pressure inside the housing 1 and the movable upper wall of the housing 6 rises up, opening the valve 8 by means of the hinge connection 7. As a result steam consumption through nozzles 9 increases. Dusty air flow, passage through housing 1 towards suction nozzle 5, meets in its path a vapor cloud formed by nozzles 9. As a result of contact with steam, dust particles coagulate and fall on the conveyor belt, reducing the fly ash

draw into the aspiration system. The most complete deposition of dust particles is achieved by controlling the amount of steam depending on the amount of dusty air that is supplied by the movable upper wall 6 of the housing 1. At the same time, by changing the cross section of the shelter case while increasing and decreasing the amount of dusty passing air air movement, which leads to an increase in the time of interaction of steam with dust particles and increases the efficiency of air supply; creases entrainment of dust particles in the suction pipe. one

The results of the aspiration

shelter and prototype with different modes of operation are summarized in the table.

The application of the invention allows to reduce the energy and energy intensity of the aspiration system, to reduce the load on the treatment plant, to increase the output of the finished product and to increase labor productivity by improving its conditions.
