Problems solved by technology

[0003] Because silane burns to generate solid silica dust, it is easy to block the air duct and the internal packing of the silane row, causing equipment blockage, affecting the operation of the equipment, and directly affecting the production process, and the ammonia water is very easy to scale, causing scaling and blockage of the equipment drainage pipe. It also affects the air volume of the equipment, so the maintenance of the silane combustion tower has become a relatively frequent daily work, and it is necessary to improve the degree of reducing equipment blockage and the efficiency of equipment maintenance through transformation

Abstract

The invention discloses a silane row dust removing device which comprises a combustion bucket and a post-treatment tower. The combustion bucket is connected with the post-treatment tower through a pipeline. A feeding port is formed in the side face of the combustion bucket. A discharging port is formed in the top of the combustion bucket. The post-treatment tower comprises a bucket body, a post-combustion chamber, a spraying device, filler and a water tank. The post-combustion chamber is arranged on one side of the upper portion in the bucket body. An air duct is arranged on the side face of the post-combustion chamber. The filler is arranged on the lower portion of the side face of the post-combustion chamber. The whole plane is filled with the filler. The spraying device is arranged on the upper portion of the side face of the post-combustion chamber. The upper portion, provided with the spraying device, of the bucket body is provided with an opening which is connected with an exhaust fan. The water tank is arranged on the lower portion of the bucket body. The upper portion, provided with the air duct, of the bucket body is provided with a cleaning port. A gas supplement device is arranged on one side of the post-combustion chamber. By the adoption of the silane row dust removing device, waste gas is effectively filtered, and pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the field of waste product discharge, in particular to a device for cleaning silane dust discharge. Background technique [0002] In the prior art, the production process of crystalline silicon solar cells is divided into five processes: texturing, diffusion, etching, coating and screen printing. In the coating process, ammonia and silane are used, and the produced The exhaust gas is processed through a silane combustion tower. The gas containing silane and ammonia gas passes through the primary combustion tube and burns through the connected compressed air. The unburned gas and ammonia gas enter the next stage, and the fresh air supplied by the equipment continues to burn. The ammonia gas is sprayed and combined with water. Ammonia water is generated, and the purified air is discharged into the atmosphere by the fan. [0003] Because silane burns to generate solid silica dust, it is easy to block the air duct and the interna...
