Integrated unsealed tank for waste heat recovery of industrial wastewater

Abstract

The invention discloses an integrated unsealed tank for waste heat recovery of industrial wastewater, and relates to the technical field of waste heat recovery tanks. The problem that in an existing tank, the tank needs to be stopped when settling sludge at the bottom of the tank body is cleaned, the normal production time of the tank body is occupied, and the production efficiency is affected issolved. The integrated unsealed tank body for waste heat recovery of industrial wastewater comprises a tank body, a water spraying disc and a supporting brush rod, wherein a wastewater inlet pipe anda wastewater overflow pipe are welded with an inclined angle of 90 degrees on the circumferential outer wall of the top end position of the tank body in an up-down interval and communicated mode; anda circular opening is formed in the center of the top end wall plate of the tank body in a penetrating manner; and a tank cover is inserted into the circular opening. The back-flushing kinetic energyof water can be used as a driving power source for cleaning the wall of a heat exchange tube; and compared with a transmission mode by adopting a mechanical rotating shaft mechanism, the structure issimple, the failure rate is low, the production cost and the manufacturing difficulty are both effectively reduced, and the integrated unsealed tank has relatively high practicability and is easy to popularize.

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....
