Background

In the prior art, the semi-coke can replace coke (metallurgical coke) and is widely used in industries such as chemical industry, smelting, gas making and the like, and in order to improve the combustion effect of the semi-coke, the semi-coke is generally prepared into semi-coke powder, then the semi-coke powder is used as a combustion raw material, however, a large amount of flue gas mixed with the semi-coke powder can be generated in the semi-coke powder preparation process, and in order to reduce the loss and air pollution of the semi-coke powder, a bag-type dust collector is generally selected to carry out dust removal operation on the flue gas containing the semi-coke powder, so that the semi-coke powder can be collected, and the air can be recovered clean;

However, because the amount of smoke dust generated in the process of preparing the semi-coke powder is large, the bag-type dust collector needs to perform frequent back flushing operation, so that the collection operation of the semi-coke powder is frequently interrupted and cannot be performed continuously, the particle diameter difference of the collected semi-coke powder is large, and the bag-type dust collector can be used after additional sieving and crushing processes are required.

Disclosure of utility model

The application aims to solve the problems that in the existing process of preparing the semi-coke powder from the semi-coke, the bag-type dust collector needs to be frequently shut down and back washed due to the large quantity of the semi-coke powder, and the particle size difference of the collected dust is large, and additional screening and crushing operations are needed.

In order to solve the technical problems, the application provides a crushing type collecting device for semi-coke dust, which comprises a separator and a dust remover which are connected in sequence through a pipeline, and further comprises a crusher for crushing semi-coke dust in flue gas with uniform particle size, wherein the crusher comprises a first cylinder body, a motor, a first charging bucket, a dispersing block and a crushing piece, the first cylinder body is vertically arranged in a straight cylinder shape, the motor is arranged at the top of the first cylinder body, the first charging bucket is arranged at the bottom of the first cylinder body, the dispersing block is arranged at the middle position inside the first cylinder body, and the crushing piece is arranged in the first cylinder body and is driven to rotate by the motor.

Because the collecting device is provided with the crusher with the crushing part, the crushing operation can be carried out on the semi-coke powder in the flue gas through the crushing part, further the semi-coke powder with relatively uniform particle size and no subsequent processing treatment is obtained, and the problems that in the process of preparing the semi-coke powder from the semi-coke, the bag-type dust collector needs to be frequently shut down and back washed due to the large quantity of the semi-coke powder and the additional screening and crushing operation are also required due to the large difference of the particle sizes of the collected dust are solved.
