AI Technical Summary

Technical Problem

Existing waste incinerators suffer from severe heat loss during combustion, making it difficult to continuously recover and utilize the heat. Furthermore, they are not convenient for intermittent feeding and ash removal, resulting in incomplete combustion and low heat transfer efficiency.

Method used

A waste combustion heat recovery device was designed, which includes components such as a base plate, a water tank, a combustion furnace, a plate heat exchanger, and a flue gas purifier. The device achieves heat recovery through the cooperation of the water tank and the flue gas purifier, and realizes intermittent feeding and ash removal through the feeding component and the ash scraping component.

Benefits of technology

It enables the continuous recovery and utilization of heat from waste incineration, avoids the impact of incomplete combustion and ash accumulation on heat transfer, and improves incineration efficiency and heat energy utilization.

Abstract

This invention discloses a waste combustion heat recovery device and its usage method, including a base plate, a first water tank, a combustion furnace, a plate heat exchanger, a second water tank, and a flue gas purifier. The first water tank is fixedly installed on one side of the upper surface of the base plate. This invention has the advantages of continuously recovering and utilizing the heat energy generated by the combustion of waste in the waste incinerator through the cooperation of the first water tank, the combustion furnace, the plate heat exchanger, the second water tank, the connecting components, the flue gas purifier, the exhaust pipe, the second water pipe, and the third water pipe. In addition, the waste incinerator can be intermittently fed into the waste incinerator through the feeding component during use, avoiding excessive compression of waste inside the waste incinerator, which would cause incomplete combustion of waste inside the waste incinerator. Furthermore, the waste incinerator can be scraped off the accumulated ash inside the waste incinerator through the ash scraping component after use.
