Collected oil removal energy-saving device for drying machine

Abstract

The invention discloses a collected oil removal energy-saving device for a drying machine. The collected oil removal energy-saving device comprises a box body, wherein the box body is divided into relatively independent left and right spaces by a sealing partition plate; the left part is a waste gas channel, and the right part is a fresh air channel; the box body is provided with a waste gas inlet below the waste gas channel, and is provided with a waste gas discharge outlet above the waste gas channel; the waste gas channel is provided with a filter screen, a lower collected oil removal device, a heat pipe and an upper collected oil removal device sequentially from the top down; the heat pipe passes through the sealing partition plate to enter the fresh air channel; the box body is provided with a fresh air inlet above the fresh air channel and is provided with a fresh air outlet below the fresh air channel; the heat pipe is arranged in the fresh air channel; the upper collected oil removal device and the lower collected oil removal device are arranged in the box body in a drawing and dismounting mode through an upper rail and a lower rail; and the filter screen is arranged in the box body in a drawing and dismounting mode through a filter screen rail. By the technical scheme, the negative effect of oily substances in waste gas on heat transfer surfaces is overcome.

Description

technical field [0001] The invention belongs to the technical field of energy saving and purification, and in particular relates to an oil-collecting and energy-saving device with an integrated design of energy saving and purification, which is suitable for energy saving and purification of setting machines and dryers in printing, dyeing and coating enterprises. Background technique [0002] At present, setting machines and dryers are the main energy-consuming equipment in the textile printing and dyeing industry. According to the difference in setting temperature and exhaust gas emission, each setting machine has about 300,000-500,000 kcal / hour of heat wasted due to exhaust emissions. Under the macro background of energy saving and emission reduction, it is of great practical significance to install energy-saving devices at the exhaust outlets of setting machines and dryers. [0003] Exhaust gas from sizing machines and dryers contains a lot of fumes and fibers. Most of the...
