High temperature flue gas waste heat utilization device

Abstract

A high temperature flue gas waste heat utilization device is composed of a condensate water tank, a condensate water pipe, a valve, a flue gas inlet, an evaporation water tank, a flue gas heat exchange pipe, a water storage tank, a flue gas outlet, a distilled water pipe and a steam drum; the condensate water tank is internally provided with a group of condensate water pipe, one end of the condensate water pipe is externally connected with a tap water source, the other end of the condensate water pipe is connected with the evaporation water tank by the valve, the condensate water tank is connected with the water storage tank by the distilled water pipe, the evaporation water tank is internally provided with a group of flue gas heat exchange pipe, one end of the flue gas heat exchange pipe is connected with the flue gas inlet, and the other end of the flue gas heat exchange pipe is connected with the flue gas outlet, the steam drum is a cylindrical body with openings at both ends, the lower end of the steam drum is connected to the upper part of the evaporation water tank; and the other end of the steam drum extends into the condensate water tank. The high temperature flue gas waste heat utilization device adopts excess high temperature flue gas in a factory workshop as a heat source, and can effectively save energy.

Description

technical field [0001] The invention relates to a waste heat utilization device for producing distilled water by using industrial high-temperature flue gas. Background technique [0002] Distilled water refers to pure water prepared by distillation. It can be divided into single and multiple distilled water. After the water is distilled once, the non-volatile components remaining in the container are removed, and the volatile components enter the initial fraction of distilled water, usually only the middle part of the fraction is collected, accounting for about 60%. [0003] The production of distilled water is to boil the source water and let it evaporate and condense for recovery, which consumes a lot of heat energy and is expensive. Other heat-evaporating substances in the source water used to make distilled water will condense into distilled water with the generation of distilled water. , such as phenols and benzene compounds that are harmful to health, and even vapori...

Problems solved by technology

[0005] However, the distilled water devices in the prior art mainly produce distilled water based on reverse osmosis and high-temperature distillation, and these two production devices need to consume a large amount of energy.
