Garbage pool heat supply system for garbage incineration power plant

Abstract

The invention provides a garbage pool heat supply system for a garbage incineration power plant. The garbage pool heat supply system comprises a power plant boiler, a discharged sewage cooling pool, garbage pool heat supply equipment, a continuous sewage discharge pipe, a continuous sewage discharge flash tank, a first tee joint and a second tee joint; the garbage pool heat supply equipment is used for transferring heat in the continuous hot discharged sewage to a garbage pool; the continuous sewage discharge port of a boiler barrel of the power plant boiler communicates with the continuous sewage discharge pipe; the continuous sewage discharge flash tank is used for reducing the pressure of the continuous hot discharged sewage; two ends of the first tee joint respectively communicate with a discharged sewage outlet of the continuous sewage discharge flash tank and the other liquid outlet of the continuous sewage discharge pipe; and a liquid inlet of the second tee joint communicates with the other end of the first tee joint, the second tee joint is provided with a first discharge port and a second discharge port, the first discharge port communicates with the garbage pool heat supply equipment, and the second discharge port communicates with the discharged sewage cooling pool. Continuous hot discharged sewage generated by the power plant boiler is recycled and utilized to serve as a heating source of the garbage pool in winter, the temperature in the garbage pool is increased, and the garbage fermentation effect in the garbage pool in the garbage incineration power plant in winter in northern areas is guaranteed.

Description

technical field [0001] The application relates to the technical field of thermal system energy saving, in particular to a garbage pool heating system for a garbage incineration power plant. Background technique [0002] Waste incineration power plants rely on the heat generated by waste incineration to generate electricity. Before the waste enters the incinerator, it needs to be stored in the waste pond. After 3-5 days of fermentation, part of the water in the waste will be separated out, so that the fermented waste is comparable to the original waste. Ratio, calorific value and furnace temperature have been increased, thereby improving the stability and economy of waste incinerator combustion. [0003] At present, my country's domestic waste has the characteristics of high water content, high ash content, low calorific value, and complex composition. Especially in winter in the northern region, the temperature in the garbage dump is low, the fermentation effect is poor, an...

Problems solved by technology

[0003] At present, my country's domestic waste has the characteristics of high moisture content, large ash content, low calorific value, and complex composition.

Especially in winter in the northern region, the temperature in the garbage dump is low, the fermentation effect is poor, and the moisture inside the garbage in some areas freezes, which affects the precipitation of water, resulting in low calorific value of the garbage entering the furnace, affecting the effect of garbage incineration, and resulting in unstable operation of the incinerator

The problem of unstable operation of incinerators in winter is common in waste incineration power plants in northern my country
