Dust suppression and fall system used in process of conveying high-dust material by belt type conveyor

Abstract

The invention relates to a dust suppression and fall system used in a process of conveying a high-dust material by a belt type conveyor. The dust suppression and fall system comprises a full-closed guide groove, a plurality of water mist nozzles, a water supply device, a plurality of electromagnetic valves and a control system, wherein the full-closed guide groove comprises a sliding plate and a belt, a cover plate is arranged above the guide groove to ensure that the guide groove is of a closed straight cylinder structure, and the tail part of the guide groove is provided with a rear blocking device; the water mist nozzles are respectively arranged on an inlet of a fall pipe, on a fall point, in a tail space of the guide groove, and inside the guide groove along the length direction of the guide groove, each water mist nozzle is arranged above the dust raising direction and faces towards the dust raising direction; the water supply device is connected with the plurality of water mist nozzles through pipelines and used for supplying water to the water mist nozzles; the electromagnetic valves are respectively arranged between the water mist nozzles and a water pump and used for controlling the water mist nozzles; and the control system is connected with the electromagnetic valves and the water supply device are used for receiving a control signal for controlling the operation of the electromagnetic valves and the water supply device. The dust suppression and fall system is capable of remarkably reducing air pollution, integrates functions of dust sealing, dust suppression and dust fall, and is simple to construct and little in maintenance quantity.

Description

technical field [0001] The invention relates to a dust suppression system, in particular to a dust suppression and dust suppression system suitable for conveying high-dust materials by a belt conveyor. Background technique [0002] At present, for enterprises such as thermal power generation and cement production, the control of dust pollution generated during fuel transportation has always been a difficult problem. Belt conveyors are commonly used material conveying equipment in thermal power plants. Materials, such as coal, generate a lot of dust during the transfer process, especially high-dust materials, such as Xinjiang Guanghui coal, which belongs to the aforementioned dust materials. It belongs to lignite and has a large dust content. It is the coal produced by China Guanghui Energy Co., Ltd. in Xinjiang, China. There are many reasons for the generation of dust at the transfer station of the material conveying system, for example, dry raw materials (low surface moist...
