Garbage storage pit heating method

Abstract

The invention discloses a garbage storage pit heating method. A water source heat pump is used for absorbing heat of industrial circulation water, a water inlet of a heat exchanger is connected with the water source heat pump, the heat exchanger is used for heating hot air on the boiler top of an incineration cross-waste-heat boiler, a draught fan is used for sending air heated by the heat exchanger to a heating device of a garbage storage pit, and garbage in the garbage storage pit is heated. The heating device is provided with a horizontal mother tube communicating with the draught fan and a vertical floral tube communicating with the horizontal mother tube. The horizontal mother tube is arranged along the periphery of the pit wall of the garbage storage pit, and the height of the horizontal mother tube is larger than the maximum garbage stacking height. The vertical floral tube vertically downwards extends to the bottom of the storage pit from the horizontal mother tube, and a plurality of small holes are distributed in the tube wall of the vertical floral tube. The garbage storage pit heating method solves the technical problems that in the northern low-temperature areas or the low-temperature areas in winter, the temperature in a garbage storage pit of a garbage incineration power plant is too low, garbage fermentation is difficult, consequently, the water content of garbage entering the boiler is high, combustion is not easy, combustion of an incinerator is not stable, and efficiency is low.

Description

technical field [0001] The invention relates to a heating method for a garbage storage pit, in particular to a heating method 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...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the object of the present invention is to provide a method for heating garbage storage pits, which solves the problem of low temperature in the garbage storage pits of waste incineration power plants in low-temperature regions in the north of the background technology or regions with low winter temperatures, and difficulty in garbage fermentation. Technical problems such as high water content, non-combustibility, unstable combustion and low efficiency of the incinerator
