Winter garbage unfreezing system and method in household garbage incineration power plant

Abstract

The invention discloses a winter garbage unfreezing system and method in a household garbage incineration power plant. The system comprises a garbage storage pit, a garbage crane, a garbage receiving hopper and a percolate pond. A percolate pump is installed in the percolate pond. The percolate pump is connected to a percolate spraying pipeline arranged above the garbage storage pit through a liquid outlet pipeline. A plurality of hot water coiled pipes are arranged at the bottom of the percolate pond. The hot water coiled pipes are externally connected with a hot water inlet pipe and a water outlet pipe. A temperature detection instrument and a valve are installed on the water inlet pipe. A temperature detection instrument is installed on the liquid outlet pipeline connected with the percolate and the percolate spraying pipeline. Due to the fact that the hot water pipeline additionally arranged at the bottom of the percolate pond is used for heating the percolate, the percolate heated inside the pond is conveyed to the spraying pipeline at the upper portion of the garbage storage pit through the percolate pump, the large amount of heated percolate is sprayed to garbage inside the garbage storage pit to be unfrozen and heated, and garbage fermentation and dehydration are promoted.

Description

technical field [0001] The invention belongs to the technical field of garbage incineration treatment, and in particular relates to a method for promoting garbage fermentation and dehydration in a low-temperature environment of a domestic garbage incineration power plant. Background technique [0002] With the rapid development of economy and urban construction, the amount of garbage is increasing year by year, and domestic waste incineration power plants are increasing year by year. Domestic waste incineration power plants are equipped with waste storage pits to store and ferment waste to increase the calorific value of waste. The natural fermentation time varies from 3 days to 10 days depending on the region and temperature, mainly because it is difficult to thaw and heat up the garbage in cold areas in winter. According to the design specifications of domestic waste incineration power plants and the rationality of the design itself, it is required that the storage of dom...
