Abstract

The invention discloses a boiler waste heat utilization device which specifically comprises a base, a water storage barrel and a top cove, a heating space is formed in the base, and a smoke outlet is formed in the top of the heating space; the water storage barrel is arranged at the top of the base, a heat exchange device is arranged in the water storage barrel, and the bottom of the heat exchange device is communicated with a matched cornice at the top of the heating space; the top cover is arranged at the top of the water storage barrel, an adjusting device is arranged in the top cover, and the bottom of the adjusting device communicates with the top of the heat exchange device; the heat exchange device comprises a flow dividing disc, the side face of the flow dividing disc communicates with spiral heat exchange pipes through rotating devices, and the multiple sets of rotating devices and the multiple sets of spiral heat exchange pipes are arranged. The invention relates to the technical field of waste heat utilization. According to the boiler waste heat utilization device, heat in smoke can be used for conducting auxiliary heating on water, heat waste is avoided, boiler heating can be more uniform, and the heat exchange efficiency can be improved conveniently.

Description

Technical field [0001] The present invention relates to the field of waste heat utilization, and is specifically a boiler waste heat utilization device. Background technique [0002] After the heat is under certain economic and technical conditions, there is no energy used in energy utilization equipment, which is excessive, abandoned energy. It includes several types of high temperature exhaust gas, cooling medium waste heat, wastewater wastewater, high temperature products and slag waste heat, chemical reaction heat, flammable waste gas waste liquid and waste heat, and high pressure fluid, there are many ways, but mainly There are three aspects: the direct utilization of waste heat, the waste heat power generation, and the comprehensive utilization of waste heat. At present, the flue gas generated during the boiler is usually discharged directly into the outside air. The heat carried in the flue gas will be discharged to the outside, and the heat in the flue gas cannot be utili...
