Dyeing and finishing workshop flue gas purification equipment waste heat utilization system

Abstract

The invention relates to a waste heat utilization system for dyeing and finishing workshop smoke purification devices. The waste heat utilization system comprises a setting machine smoke purification device, a living quarter bathroom water tank, a standby water tank and a workshop water utilization device, and is characterized in that the hot water outlet end of the setting machine smoke purification device is connected with the living quarter bathroom water tank and the standby water tank; the standby water tank is connected with the workshop water utilization device; a water return opening of the living quarter bathroom water tank is connected with a first water pump; the first water pump is connected with the water inlet of the setting machine smoke purification device; the first water outlet of the standby water tank is connected with the workshop water utilization device; the second water outlet of the standby water tank is connected with a second water pump; the second water pump is connected with the water inlet of the setting machine smoke purification device; a temperature measurement probe is arranged at the hot water outlet end of the setting machine smoke purification device. By means of the waste heat utilization system, waste heat of the dyeing and finishing devices can be fully recycled, reasonable regulation can be conducted according to the waste heat temperature, and it is ensured that the waste heat is sufficiently utilized.

Description

technical field [0001] The invention relates to a waste heat recovery system, in particular to a waste heat utilization system of flue gas purification equipment in a dyeing and finishing workshop, which belongs to the technical field of dyeing and finishing machinery. Background technique [0002] Dyeing and finishing equipment, such as: setting machine, air compressor, tank steamer, etc., are all heated by oil heating, steam heating, gas heating or electric heating, and then the natural air is heated and sent to the dyeing and finishing equipment by the fan Drying room, and then the air nozzle inside the drying room sprays the heated gas onto the surface of the fabric, and the cycle repeats. The resulting waste gas is generally directly discharged into the atmosphere by the waste gas exhaust fan and the exhaust air duct, which causes a serious waste of heat energy. [0003] The current waste heat recovery system uses waste heat directly for water use in bathrooms, etc. Ho...

Problems solved by technology

The resulting waste gas is generally directly discharged into the atmosphere by the exhaust gas exhaust fan and the exhaust duct, which causes a serious waste of heat energy.

[0003] The current waste heat recovery system uses waste heat directly for water use in bathrooms, etc. However, due to the different waste heat temperatures from different equipment sources in the production process, the waste heat temperature of the same equipment will also vary greatly during the day, and the waste heat is used for a single purpose. Recycling, there is often a large change in water temperature after waste heat heating, which makes it inconvenient to use
