Electrical control device of town domestic garbage treatment system

Abstract

The invention discloses an electrical control device of a town domestic garbage treatment system. The electrical control device of the town domestic garbage treatment system is used for controlling the start, the stop and the protection of a three-phase asynchronous motor by the garbage treatment system. The electrical control device (9) is provided with a control computer or a PLC (programmable logic controller) control module, wherein the electrical control device (9) is provided with an overload protection circuit, an open-phase protection circuit, an overcurrent protection circuit, an undervoltage protection circuit, a short-circuit protection circuit and an overheat protection circuit. By adopting the above technical scheme, town domestic garbage is subjected to advanced treatment; a harmful gas in the garbage can be decomposed; meanwhile, a harmless substance in the garbage can be also thinned; part of substances are enabled to float and circulate; the labor intensity in a treatment process is greatly lowered; lots of manpower and material resources are saved; the garbage is used as a production raw material; an organic matter and an inorganic matter in the garbage are separated and reasonably utilized, so as to produce organic fertilizer and a building block material; a nondegradable pollutant is used for producing a building heat insulating material; the harmlessness and the reclamation of the garbage are realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection engineering. More specifically, the present invention relates to an electrical control device of a municipal solid waste treatment system. Background technique [0002] With the rapid development of our country's economy, a lot of resources are consumed and a lot of waste is produced, which seriously affects and restricts economic development and threatens people's living quality. Economic development and pollution control have become the consensus of modern society. The direction of environmental protection work is to implement the national development strategy of sustainable development and creating a harmonious society. Environmental protection is a basic state policy of our country. The country has listed the energy-saving and environmental protection industry as one of the seven strategic emerging industries that the country has accelerated its cultivation and development. ...

Problems solved by technology

Among them, sanitary landfill wastes a lot of land resources, and it is easy to cause pollution to groundwater sources; incineration for power generation can reduce the volume of waste by 50% to 95%, but it is expensive and expensive, and it will release dioxins, mercury, etc. Harmful substances, residual slag and dust are also toxic and harmful, and a large amount of recyclable resources are burned; the composting cycle is long, and organic and inorganic substances need to be separated before they can be recycled
