Environment-friendly heat exchange device for industrial sewage waste heat recovery

Abstract

The invention relates to the technical field of industrial sewage treatment, in particular to an environment-friendly heat exchange device for industrial sewage waste heat recovery. The environment-friendly heat exchange device comprises a waste heat recovery box; a water inlet connector is arranged at the upper end of the waste heat recovery box; a water outlet connector is arranged in the middleof the lower end of the waste heat recovery box; a filtering inner cavity is formed in the upper end of an inner cavity of the waste heat recovery box; and a mounting inner cavity is arranged in themiddle of the inner cavity of the waste heat recovery box. The environment-friendly heat exchange device has the beneficial effects that a shunting heat exchange pipe is arranged, so that a large-caliber sewage discharge flow column is shunted into a plurality of small flow columns, the contact area of sewage with the outside is increased, the heat exchange efficiency is improved, meanwhile, the heat recovery rate is increased, and rapid and efficient recovery of energy sources is realized; and a lifting plate moving up and down is arranged, hot water in a heat exchange inner cavity is stirredup and down in cooperation with a transverse flow channel and a longitudinal flow channel, and water flow on the outer wall of the shunting heat exchange pipe and water flow on the outer edge of theheat exchange inner cavity are exchanged, so that the heating and heat exchange efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of industrial sewage treatment, in particular to an environment-friendly heat exchange device for industrial sewage waste heat recovery. Background technique [0002] In the existing industrial production process, a large amount of industrial high-temperature wastewater will be generated due to the needs of cleaning, heat dissipation, filtration and tempering. These wastewaters have the characteristics of large volume, high temperature and high pollution degree, and cannot be directly used. [0003] Due to the characteristics of industrial sewage, in order to protect the environment, the sewage cannot be discharged directly during treatment. At the same time, the high temperature is not conducive to the recycling and filtration of sewage, and a large amount of sewage not only causes waste of water resources, but also directly dissipates heat and energy utilization. rate drops. [0004] Therefore, an environ...

Problems solved by technology

[0002] In the existing industrial production process, a large amount of industrial high-temperature wastewater will be generated due to the needs of cleaning, heat dissipation, filtration, conditioning and other processes. These wastewaters have the characteristics of large volume, high temperature and high pollution degree, and cannot be directly used.

[0003] Due to the characteristics of industrial sewage, in order to protect the environment, the sewage cannot be discharged directly during treatment. At the same time, the high temperature is not conducive to the recycling and filtration of sewage, and a large amount of sewage not only causes waste of water resources, but also directly dissipates heat and energy utilization. rate drop

[0004] To this end, an environmentally friendly heat exchange device for waste heat recovery of industrial sewage is provided to solve the problem of heat recovery of sewage
