Exhaust system of silicon carbide smelting workshop

Abstract

The invention belongs to the technical field of silicon carbide processing, and relates to an exhaust system of a silicon carbide smelting workshop. The exhaust system includes a gas gathering building, a first exhaust mechanism and a dust removal tower. The first exhaust mechanism includes a first main air pipe, a first connecting pipe, a first valve, a first induced draft fan and a first branchair pipe. The diameter of the first main air pipe decreases gradually from the middle to the two ends, and the two ends are of closed structures. One end of the first connecting pipe communicates withthe largest pipe diameter of the first main air pipe, the first valve is arranged on a pipeline, the other end of the first connecting pipe is connected with the first induced draft fan and the dustremoval tower in sequence, one end of the first branch air pipe communicates with a pipeline of the first main air pipe, and the other end of the first branch air pipe extends into the gas gathering building. According to the exhaust system, by arranging the main air pipe with gradually varied pipe diameter, the exhaust effect and exhaust efficiency of the smelting workshop can be effectively improved; moreover, according to the smelting demand, an exhaust area can be flexibly used, the energy and cost are saved; and the layout of the system is more reasonable, and the processing cost is effectively saved.

Description

technical field [0001] The invention belongs to the technical field of silicon carbide processing and relates to an exhaust system for a silicon carbide smelting workshop. Background technique [0002] The smelting of silicon carbide belongs to the field of large-scale chemical industry. The scale of the smelting furnace is very large, so the size of the smelting workshop is also large. At the same time, during the smelting process of silicon carbide, a variety of harmful gases will be produced, such as those produced by the basic reaction of smelting Carbon monoxide, sulfur dioxide, hydrogen sulfide, methyl mercaptan, etc. produced by sawdust and coke have caused great harm to the environment of the smelting workshop. Due to the unreasonable layout of the existing exhaust system in the smelting workshop and the excessively traditional selection of exhaust pipes and structures, it has caused problems such as poor exhaust effect and low exhaust efficiency. At the same time, t...

[0002] The smelting of silicon carbide belongs to the field of large-scale chemical industry. The scale of the smelting furnace is very large, so the size of the smelting workshop is also large. At the same time, during the smelting process of silicon carbide, a variety of harmful gases will be produced, such as those produced by the basic reaction of smelting Carbon monoxide, sulfur dioxide, hydrogen sulfide, methyl mercaptan, etc. produced by wood chips and coke have caused great harm to the environment of the smelting workshop

Due to the unreasonable layout of the existing exhaust system in the smelting workshop and the excessively traditional selection of exhaust pipes and structures, it has caused problems such as poor exhaust effect and low exhaust efficiency. At the same time, there are also problems that cannot be handled flexibly Exhaust from different smelting areas results in a large degree of energy waste, which virtually increases the cost of smelting silicon carbide, which is not conducive to the long-term development of the enterprise
