Textile industry waste heat recovery system with automatic cleaning and fire extinguishing functions

Abstract

The invention discloses a textile industry waste heat recovery system with automatic cleaning and fire extinguishing functions. The system comprises a flue gas cavity, a waste heat recovery cavity, an oil stain storage box, a cleaning liquid box, a pump and a filter, a plurality of heat pipes are fixedly arranged in the flue gas cavity, a plurality of hollow spray heads are horizontally arranged at the top end in the flue gas cavity, a flow guide hopper is fixedly arranged at the bottom of the flue gas cavity, a bottom through opening of the flow guide hopper is connected with a sewage collection conversion valve through a guide pipe, through openings in the left side and the right side of the sewage collection conversion valve are provided with a first discharge short pipe and a second discharge short pipe, and a gas inlet pipe is installed at the gas inlet end of the outer wall of the left side of the flue gas cavity. According to the textile industry waste heat recovery system with the automatic cleaning and fire extinguishing functions, the problem that the heat exchange efficiency is greatly reduced due to the fact that greasy dirt is coked on the heat exchange surface is solved, the heat exchange efficiency is improved, the problem of fire can be prevented, and certain use value and popularization value are achieved.

Description

technical field

[0001] The invention relates to the technical field of waste heat recovery, in particular to a waste heat recovery system for the textile industry with automatic cleaning and fire extinguishing functions. Background technique

[0002] In the textile industry, especially the printing and dyeing industry, the temperature of the flue gas discharged from the drying, setting and other processes is relatively high, especially the setting machine, the exhaust gas temperature is as high as 150°C-210°C, and these flue gases enter the Industrial oil fume purifiers cause a lot of waste of heat energy, and cause excessive cooling water consumption and poor treatment effects for industrial oil fume purifiers; the existing waste heat recovery systems use shell and tube heat exchange, heat pipe type For heat exchange, even heat pump heat exchange, the above heat exchange methods are relatively effective when newly installed, but after a period of use, due to the coking of o...
