Control system of solid garbage degradation device

Abstract

The invention relates to the field of chemical engineering, and relates to a control system of a solid garbage degradation device. The control system of the solid garbage degradation device comprises a garbage gas stratified sampling device, an automatic garbage gas sampling device, a garbage gas analyzer, a water supply pipe, a water injection pump, a ground penetrating radar, a water content controller and a central processor, wherein the water supply pipe is provided with a plurality of water through holes, and is arranged in a garbage dump; the water injection pump is connected with the water supply pipe; the ground penetrating radar is connected with the input end of the water content controller; the output end of the water content controller is connected with the water injection pump; and the central processor is connected with the garbage gas analyzer, the water content controller, and a gas extracting pump and a gas injection pump in the garbage dump respectively. The control system of the solid garbage degrading device provided by the invention not only can monitor gas content in a garbage degradation reaction process, but also can monitor the water content; and the control system provided by the invention achieves the aim of improving the degradation efficiency through controlling more conditions in the garbage degradation reaction process.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a control system of a solid waste degradation device. Background technique [0002] With the continuous development of social economy, more and more industrial and domestic solid wastes need to be biodegraded. Biodegradation includes anaerobic degradation and aerobic degradation. Compared with anaerobic degradation, aerobic degradation of waste is faster, so it has received widespread attention. [0003] At present, devices for aerobic degradation of solid waste have appeared on the market. For example, the device provided by the patent "Device for Rapidly Degrading Solid Waste" (Patent No. 200420009079.6, China) uses a composite compensation well arrangement method combining gas injection and pumping to enable a controllable three-dimensional flow of oxygen in garbage , and the coverage and uniformity of oxygen in the garbage dump are high. However, the control system it ado...

[0006] ΔQ is the heat generated by the degradation reaction; it can be seen from the reaction formula that the content of water is an influencing factor of the degradation reaction, and the control device in the above patent includes monitoring devices such as gas content sensors and garbage gas automatic samplers. The control device can only It is used to monitor the oxygen content and carbon dioxide content in the garbage degradation reaction, but the moisture content cannot be monitored, so that when the moisture content is too high, the flow of oxygen is hindered, and the moisture content is too low to reduce the degradation rate of the garbage and overheat the garbage.
