Coal dust capture (collection of coal dust) refers to an aid to the coking coal preparation coal plant. A large amount of dust is generated in the process of crushing the coking coal and the process of distributing the coal material on the tops of the coal blending tank and the coal storage tower, so that the environment is polluted, the health of workers is harmed, and the coal dust explosion risk is caused. This phenomenon is particularly serious when the moisture content of coal is low. Effective dust collection and sealing measures must therefore be taken.
In the existing power plant, a movable dust collecting device is usually modified by adopting a diesel truck chassis, and a Roots vacuum pump, a multistage dust removal system, a hydraulic system, an air compression system and the like are arranged on the chassis. The chassis diesel engine drives the chassis when the vehicle runs, and the same diesel engine drives the Roots blower to generate vacuum when dust collection is carried out, so that dust is sucked into the vehicle body dust collection system through a pipeline. The dust-containing airflow in the vehicle body is subjected to centrifugal separation and high-efficiency co-separation, the dust is collected in the vehicle body, and clean air is discharged into the atmosphere through the silencer. After the coal powder in the vehicle body is fully collected, the vehicle runs to a coal yard, and the collected dust is poured into a coal pile through the vehicle body pouring. The average distance of the dust collection vehicle is less than 3-4 kilometers per day, the dust collection time of the vehicle is about 4-5 hours per day, a great amount of pollution is generated in the process, and the energy consumption is huge.
Due to the working characteristics of the vehicle, the working range of the vehicle is limited to a coal yard of a factory, the running distance per day is short, and the requirement on the cruising ability of the vehicle is not high. Due to the characteristic of dust collection operation, the vehicle needs to be started and stopped frequently. This mode of operation of the operating jog is very unsuitable for the characteristics of a diesel engine.

(2) The movable dust collecting device is suitable for places which are not suitable for water washing, such as a bunker bay, a coal crushing machine room, a furnace entering sampling device and the like of a coal-fired power plant, and is cleaned by utilizing vacuum dust collection.
(3) In China, most of mobile dust collecting devices are driven by diesel engines. The movable dust trapping device is carried by a vehicle chassis, the designed working point of an engine of the vehicle chassis is low-speed large torque, and the working requirement of the Roots blower is high-speed small torque determined by the working characteristics of the Roots blower. And therefore, the engine is intended to operate in a high-speed region for a long period of time while operating. The working noise is high, the engine is seriously abraded, and the diesel engine is easy to burn engine oil due to abrasion of piston rings after long-term high speed, so that the emission pollution of the engine is serious. Meanwhile, the speed regulation technical requirement of the diesel engine is higher than that of the motor, the adaptability of the working rotating speed of the diesel engine is far lower than that of the motor, and the power supply of a power plant is very easy to realize, so that the driving of the vacuum pump by adopting electric driving instead of the diesel engine is an inevitable technical route.
(4) All adopt electric drive, solved the environmental protection problem that diesel engine drive brought, practiced thrift the oil, reduced cost, economic benefits and social are showing.
