Intelligent multilevel inverter microwave and optical wave crawler speed-regulating tunnel type coal drying device

Abstract

The invention relates to an intelligent multilevel inverter microwave and optical wave crawler speed-regulating tunnel type coal drying device, which comprises a tunnel type box and a metal crawler connected to a variable frequency motor, wherein the metal crawler is formed by splicing a plurality of crawler slots; each crawler slot is provided with a plurality of orderly arrayed small holes; a microwave magnetron set and an optical wave metal halide lamp set are arranged above the metal crawler in the tunnel type box; and the coal is dried through the microwave and optical wave. The invention has the advantages that a microcomputer control system can ensure that the coal is not broken and cracked under the condition of microwave drying technique, which meets the drying demand of cleanly produced coal, decreases the energy consumption and is free from pollution.

Description

technical field [0001] The invention relates to an industrial clean and productive briquette drying equipment, in particular to an intelligent multi-stage frequency conversion microwave and light wave crawler speed regulating tunnel type briquette drying equipment. Background technique [0002] Most of the existing briquette drying equipment adopts kiln drying or electric direct heating furnace for drying. In the process of briquette drying, the kiln has high technical and process requirements and is not easy to control. If the temperature control of the briquette is not well controlled in the kiln drying process, it will easily lead to cracking, the cost of the kiln is high, and it occupies a large space. During the drying process, the kiln needs to burn coal to generate the heat required for drying the briquettes. The carbon dioxide, sulfide and other gases and residues produced after coal combustion will cause serious pollution and damage to the atmosphere and the env...

AI Technical Summary

Problems solved by technology

[0002] Most of the existing briquette drying equipment adopts kiln drying or electric direct heating furnace for drying. In the process of briquette drying, the kiln has high technical and process requirements and is not easy to control.

Poor temperature control of briquettes during the kiln drying process will easily lead to cracks, high cost of kiln construction, and large space occupation

During the drying process, the kiln needs to burn coal to generate the heat required for drying the briquettes. The carbon dioxide, sulfide and other gases and residues produced after coal combustion will cause serious pollution and damage to the atmosphere and the environment; The dry energy consumption is too high, the production cost is high, and it is impossible to save energy and reduce consumption

Because the microwave and light wave drying technology is not easy to master in the drying of briquettes, and it is easy to ignite. superior
