Accumulated-oil-removing energy-saving device

Abstract

The invention discloses an accumulated-oil-removing energy-saving device, which comprises a box body, wherein the box body is partitioned into a left space and a right space by a seal partitioning plate, wherein the left space and the right space are relatively independent, a waste gas channel is formed at the left part, and a fresh air channel is formed at the right part; the box body is provided with a waste gas inlet below the waste gas channel and is also provided with a waste gas discharge hole above the waste gas channel, a filtering screen, a lower accumulated-oil-removing device, a heat pipe and an upper accumulated-oil-removing device are arranged in the waste gas channel from bottom to top in sequence, and the heat pipe passes through the seal partitioning plate and enters into the fresh air channel; the box body is provided with a fresh air inlet above the fresh air channel and a fresh air outlet below the fresh air channel, and the heat pipe is arranged in the fresh air channel; and the upper accumulated-oil-removing device, the lower accumulated-oil-removing device as well as a filtering screen and a shell of the box body are isolated respectively by heat-insulation materials. The upper accumulated-oil-removing device, the lower accumulated-oil-removing device, the heat pipe and the filtering screen are all arranged inside the box body, and a connection part between the box body and the outside is sealed by seal materials. According to the technical scheme disclosed by the invention, the problem of adverse impact of oil substances in waste gases on the heat exchange surface is solved.

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...
