Problems solved by technology

[0002] At present, the semi-coke furnace can only use 30mm-80mm lump coal. In the case of fully-mechanized coal mining, the lump coal is only 25%, resulting in limited raw material coal sources. In addition, the production capacity of semi-coke approved construction far exceeds the supply of lump coal, resulting in a relative surplus of production capacity. The price of raw lump coal is high, and the operating profit of semi-coke enterprises is low

Abstract

The invention relates to a gas collecting and dust settling coal loosening device. The gas collecting and dust settling coal loosening device comprises a gas guide pipe and a gas guide channel communicated with the gas guide pipe, the gas guide channel comprises a horizontally arranged main channel and multiple auxiliary channels which are perpendicular to the main channel and inlaid in the main channel, the main channel is provided with the gas guide pipe communicated with the main channel, and port sealing plates are arranged at the two ends of the main channel and the auxiliary channels; the device further comprises a strong plate; multiple dust removal plates are arranged in the auxiliary channels in parallel, the dust removal plates are arranged in the length direction of the auxiliary channels, holes are formed in the dust removal plates, fixed rods are arranged on the lower edges of the dust removal plates, coal loosening machines are arranged in the fixed rods, and all layers of the coal loosening machines on the fixed rods connected to the same dust removal plates are located on the same horizontal plane, and all layers of the coal loosening machines on the fixed rods on the adjacent dust removal plates are arranged staggerly. Accordingly, the dust removable plates arranged in the auxiliary channels can play a dust settling role; by means of the coal loosening machines, the effect of lowering bed resistance is achieved, and dredging and gas guiding effects are achieved.

Description

technical field [0001] The invention designs a gas-collecting, dust-reducing and coal-scavenging device, which specifically belongs to the technical field of low-temperature dry distillation of mixed coal. technical background [0002] At present, the semi-coke furnace can only use 30mm-80mm lump coal. In the case of fully-mechanized coal mining, the lump coal is only 25%, resulting in limited raw material coal sources. In addition, the production capacity of semi-coke approved construction far exceeds the supply of lump coal, resulting in a relative surplus of production capacity. The price of raw lump coal is high, and the operating profit of semi-coke enterprises is low. In order to make full use of the mixed coal below 30mm, it is very important to develop the necessary process technology. At present, the vertical furnace is used to carry out the pyrolysis of mixed coal, only the two problems of large oil dust content and large pressure drop of coal bed are difficult to ...
