Combined waste heat recovery device of setting machine

Abstract

The invention discloses a combined waste heat recovery device of a setting machine. The combined waste heat recovery device of a setting machine comprises a housing and multiple heat pipes. The multiple heat pipes are removably arranged in the housing and form included angles of 5 to 10 degrees with a horizontal plane. A sealing body is arranged in the middle of the housing and divides the interior of the housing into an independent left chamber and an independent right chamber. All the heat pipes pass through the sealing body and stretch into the independent left chamber and the independent right chamber. An air inlet and an outlet of hot air subjected to heat exchange are respectively arranged at the top and the bottom of the independent left chamber. A hot waste gas inlet and an outlet of hot waste gas subjected to heat exchange are respectively arranged at the top and the bottom of the independent right chamber. The combined waste heat recovery device which is a combined heat pipe exchanger is arranged on the top of a setting machine. A setting machine hot waste gas-outlet located on the top of the setting machine is directly communicated with the hot waste gas inlet. A setting machine gas-inlet located on the top of the setting machine is directly communicated with the outlet of hot air subjected to heat exchange. The combined waste heat recovery device of a setting machine has a small volume, is convenient for installation and disassembly, is convenient for maintenance and cleaning, and has a high waste heat recovery rate.

Description

technical field [0001] The invention relates to a waste heat recovery device, in particular to a combined type setting machine waste heat recovery device in the printing and dyeing industry. Background technique [0002] The setting machine is one of the main energy-consuming equipment in the textile printing and dyeing industry. It is a device that uses hot air to dry, finish and set the fabric. Generally, the temperature of the hot air required in the setting machine is about 200°C, and the temperature of its exhaust gas is generally about 170°C, and a large amount of waste heat is discharged into the air. If the loss of fuel combustion and heat dissipation of the body are added, it is estimated that more than 90% of the heat input into the setting machine is scattered into the atmosphere by the exhaust. The heat consumed by the actual processing of the fabric only accounts for 2.9% of the heat input to the setting machine. The dissipated heat not only wastes energy but ...

AI Technical Summary

Problems solved by technology

However, the oil and fiber dust in the exhaust gas bring the disadvantage that the heat pipe is not easy to clean, which still limits the long-term stable use of the waste heat recovery device of the setting machine.

[0003] At present, there are some waste heat recovery products of setting machine on the market, but the common problems are: large size, inconvenient installation; long pipelines entering and leaving the waste heat recovery device of setting machine, large heat loss; the heat pipe is fixed (such as welding, etc.) Installed in the shell of the waste heat recovery device of the setting machine, it is difficult to disassemble for quick maintenance. In the event of blockage or other failures, the maintenance workload is very large and time-consuming, which will affect the production of the user unit
