An automatic temperature control device for waste heat recovery and centralized heating of bath liquid

Abstract

Disclosed is an automatic temperature control device for waste heat recycle and bath solution concentrated heating. The automatic temperature control device includes a waste heat acquisition device and an automatic temperature controlling device connected with the waste heat acquisition device. The waste heat acquisition device includes a hot wind channel and a spring coil pipe which winds the periphery surface of the hot wind channel. The automatic temperature controlling device includes a plurality mutually communicated heat exchanging water tanks and coating baths. The coating baths are in loop connection with the heat exchanging water tanks through bath solution inlet pipes and bath solution outlet pipes. A plurality of heat exchanging coil pipes which are in mutual communication are arranged in the heat exchanging water tanks. The heat exchanging coil pipes are in communication with the spring coil pipe of the waste heat acquisition device. The automatic temperature control device recycles waste heat generated by exhaust gases discharged by other devices (waste heat which is not recycled is discharged externally through gas ducts) so that an environment protection role is played; and water is used as a conduction medium and a temperature difference not larger than 60 DEG C is used to heat the bath solution so that harmful effects because of overly high local temperature of the bath solution are not caused.

Description

technical field [0001] The invention relates to a heat recovery and utilization device, in particular to an automatic temperature control device for waste heat recovery and centralized heating of bath liquid. Background technique [0002] At present, flue gas is the main way for general energy-consuming equipment to waste energy. For example, the exhaust gas of boilers consumes about 15% of the energy. Gas emissions; In today's society, energy conservation has become the fifth energy source after coal, electricity, oil and natural gas, and the flue gas produced by boilers and other equipment is discharged into the atmosphere, which not only wastes heat but also causes environmental damage. Pollution. [0003] In the electroplating production equipment of the existing factory, all the baths are heated directly by titanium electric heating tubes, which have the following disadvantages: high power consumption; direct contact between the heating tube and the bath will cause the...
