Embodiment Construction

[0029] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0030] Such as figure 1 , 2 , 3, a kind of garbage fermentation system includes: garbage storage pit 22, garbage receiving and pretreatment area, crane control room 19, crane, hopper, incinerator 21, the crane control room controls the crane, and the garbage that is fermented is sent into Incinerate in an incinerator, and a waste heat boiler 23 is set above the incinerator for waste heat recovery. In order to promote the garbage fermentation in the garbage storage pit, a garbage storage pit heating system is installed to heat the garbage in the garbage storage pit and a detection and control device is installed to control the temperature of garbage fermentation.

Abstract

The invention discloses a heating system of a garbage storage pit. The heating system comprises a primary air inlet system, an upper heating device, a bottom heating device and a storage pit internal heating device, wherein the upper heating device is used for heating air of the primary air inlet system; the primary air inlet system is used for feeding air heated by the heating device into the garbage storage pit; the bottom heating device surrounds the bottom of the garbage storage pit, and is used for heating the bottom of the garbage storage pit; and the storage pit internal heating device is used for heating garbage in the storage pit. According to the heating system, the top and the bottom of a garbage stacking surface are heated at the same time, so that the temperature of the garbage storage pit is effectively increased, fermentation and dehydration of garbage are facilitated, the calorific value of garbage fed into an incinerator is increased, and combustion of the incinerator is more stable; and besides, the temperature in the garbage storage pit is increased through fully utilizing hot water generated from a waste heat utilization system of hot air at the upper part of an incineration bridge and industrial circulating water, so that the primary air inlet temperature is increased, and the heat efficiency of the incinerator is improved.

Description

technical field [0001] The invention relates to a heating system for a garbage storage pit, in particular to a heating system for a garbage storage pit in the field of industrial environmental protection, which is suitable for heating the garbage storage pit of a garbage incineration power plant. Background technique [0002] With the development of the economy and the improvement of people's living standards, more and more municipal solid wastes have been produced, and waste incineration power plants have emerged as the times require. Waste incineration power generation can effectively recycle, reduce, and harmless urban domestic waste. It not only makes full use of the calorific value of waste, but also uniformly treats harmful components generated by combustion through the flue gas treatment system, reducing environmental impact. pollution. [0003] However, due to the high water content and low calorific value of the garbage, it is not easy to burn, which will easily ca...
