[0002] Domestic waste refers to solid waste generated in daily life or in activities that provide services for daily life, as well as solid waste that is deemed domestic waste by laws and administrative regulations. This primarily includes household waste, market and commercial waste, waste from public places, street sweeping, and waste from enterprises and institutions. Domestic waste can be treated by incineration in a furnace. Incineration involves placing the waste in a high-temperature furnace to fully oxidize the combustible components. The heat generated is then used to generate electricity and heat the environment.

[0003] However, the existing incinerators have certain drawbacks when in use. Usually, various domestic garbage is directly put into the furnace of the incinerator for incineration. Some domestic garbage with a high water content cannot be dried during combustion, resulting in incomplete combustion of the garbage and low combustion efficiency. At the same time, there is a large amount of heat loss during combustion in the incinerator, and the remaining heat cannot be effectively utilized, resulting in a waste of resources and an increase in the cost of garbage disposal. For this reason, the utility model proposes a waste heat recovery and heat exchange device for a combustion furnace to solve the above problems. Utility Model Content

[0010] Preferably, a hopper is integrally formed at the rear end of the outer tank body, and the hopper is arranged in a bucket shape.

[0011] Preferably, when the outer tank body rotates, garbage in the cavity between the filter layer and the outer tank body flows from the rear end of the outer tank body to the front end of the outer tank body.

[0012] Preferably, the filter layer is made of a high-density steel wire mesh, the outer tank body is made of a heat-insulating material, and the inner liner layer is made of a stainless steel plate.

[0013] Preferably, the flue gas outlet is a circular tube structure, and a pipe adapter is rotatably installed at the port of the flue gas outlet through a sealed bearing, the end of the pipe adapter is rotatably installed on the mounting frame, and the end of the pipe adapter is connected to the flue gas waste heat recovery equipment through the flue gas pipe.

A ring gear 7 is fixedly mounted on the middle side wall of the outer tank body 1. The ring gear 7 is driven by a drive motor. The filter layer 2 is arranged in the inner cavity of the outer tank body 1, and the outer side wall of the filter layer 2 is connected to the inner side wall of the outer tank body 1 by a spiral feeding blade 5. The inner tank layer 3 is arranged on the filter layer. 2, and the outer side wall of the inner liner layer 3 is connected to the inner side wall of the filter layer 2 through a connecting column 6. The front side end of the inner liner layer 3 is hingedly installed with an inner liner door 8, the rear side end of the inner liner layer 3 is integrally formed with a smoke exhaust port 9, and an ignition device is provided in the inner liner layer 3.

The filter layer 2 is set to allow the garbage to flow between the outer tank body 1 and the filter layer 2, so that the water vapor formed by drying passes through the filter layer 2 and enters between the filter layer 2 and the inner liner layer 3, so that the water vapor can be better discharged from the outer tank body 1. Example 3

[0028] On the basis of Example 2, the flue gas outlet 9 is a circular tube structure, and a pipe adapter 11 is rotatably installed at the port of the flue gas outlet 9 through a sealed bearing 10.
