Description

Technical Field

[0001] The utility model relates to the technical field of waste heat utilization, and more specifically, to a waste heat utilization device based on a solid waste treatment process. Background Art

[0002] Solid waste treatment methods are engineering and technical methods for recovering and utilizing resources from solid waste. According to the source, nature, characteristics and environmental hazards of solid waste, the technology for disposing, recycling and utilizing it is an extremely important part of environmental engineering. At present, most solid waste treatment methods use incinerators for incineration. For example, the prior art publication number (CN217875858U) describes a waste heat utilization device based on a solid waste treatment process, which connects the air outlet of the spiral pipe with the air inlet of an external blower, and then connects the delivery pipe with the external domestic water pipe, and then adds an appropriate amount of water to the space formed between the water storage shell, the pretreatment barrel and the spiral pipe, and then The solid waste that needs to be pretreated is put into the pretreatment barrel, and finally the solid waste is placed in the solid waste incinerator for incineration, and the external blower is started to accelerate the incineration speed of the solid waste in the solid waste incinerator. The high-temperature flue gas generated after the combustion of the solid waste enters the spiral pipe through the transmission pipe. At this time, the heat of the high-temperature flue gas will dry and heat the solid waste in the pretreatment barrel through the copper heat exchange plate, and the setting of the baffle can greatly increase the stroke of the high-temperature flue gas, so that its heat exchange is sufficient. At the same time, the staff controls the operation of the motor by controlling the switch group, and the rotation of the motor output shaft drives the rotating rod and the spiral piece to rotate synchronously.

[0003] When the above device is in use, the spiral blades will continuously stir the solid waste in the pretreatment barrel, so that the solid waste can be dried and preheated more comprehensively, the treatment efficiency can be improved, and the waste heat generated by the solid waste treatment can be effectively and reasonably utilized. The hot smoke generated during the solid waste treatment heats the spiral pipe, thereby heating the solid waste raw materials. However, the efficiency of heating the spiral pipe by hot smoke is poor, and the heat loss is fast, thereby worsening the effect of preheating and utilizing the solid waste treatment.
