An integrated unsealed tank body for recovery of waste heat from industrial wastewater

Abstract

The invention discloses an integrated unsealed tank body for waste heat recovery from industrial waste water, relates to the technical field of waste heat recovery tanks, and solves the problem that the existing tank body needs to be shut down when cleaning the settled sludge at the bottom of the tank body, which takes up The normal production time of the tank is affected, which affects the production efficiency. An integrated unsealed tank body for waste heat recovery from industrial wastewater, including a tank body, a water spray disc and a support brush rod. The outer wall of the circumference at the top of the tank body is welded at an angle of 90° up and down and connected with a waste water tank at intervals up and down. There is an inlet pipe and a waste water overflow pipe, and a circular opening runs through the center of the top wall plate of the tank body, and the tank cover is plugged and plugged on the circular opening. The recoil energy of the water used in the present invention is used as the driving power source for cleaning the heat exchange tube wall, intersecting with the traditional mechanical shaft mechanism for transmission, the structure is simple, the failure rate is low, the production cost and manufacturing difficulty are effectively reduced, and it has good practicability and is easy to use. promote.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery tanks, in particular to an integrated unsealed tank body for recovery of waste heat from industrial waste water. Background technique [0002] A large amount of industrial wastewater is produced in the production process of many industries. Apart from containing a large amount of industrial pollutants, most of these wastewaters have a common characteristic-high temperature, and the discharge of high-temperature industrial wastewater into the environment will cause great harm to animals and plants. Moreover, high-temperature industrial wastewater contains a large amount of heat. If it is directly discharged into the environment, it will cause energy waste. This requires the use of a tank for industrial wastewater waste heat recovery. [0003] For example, the patent No. CN201320112857.3 discloses a waste heat recovery tank for waste water, which includes a tank body and a filter screen....

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an integrated unsealed tank body for waste heat recovery from industrial waste water, so as to solve the problem that the deposited impurities on the surface of the internal water exchange pipes proposed in the above background technology will affect the heat exchange efficiency of the water exchange pipes. Moreover, the sediment on the surface of the heat exchange pipe is not easy to clean, and it is necessary to manually enter the tank for cleaning. The operation is extremely troublesome, and the tank needs to be shut down when cleaning the settled sludge at the bottom of the tank, which takes up the normal production time of the tank , which affects the production efficiency
