Dryer with oil removing and collecting energy-saving device

Abstract

The invention discloses a dryer with an oil removing and collecting energy-saving device, which comprises the oil removing and collecting energy-saving device. The oil removing and collecting energy-saving device comprises a box body. The box body is divided into two left and right independent spaces through a sealing diaphragm; the left part of the box body is used as a waste gas passage; the right part of the box body is used as a fresh air passage; a waste gas inlet is arranged in the box body and below the waste gas passage; a waste gas discharge outlet is arranged in the box body and above the waste gas passage; a filter screen, a lower oil removing and collecting device, a heat pipe and an upper oil removing and collecting device are sequentially arranged in the waste gas passage from bottom to top; the heat pipe passes through the sealing diaphragm to enter the fresh air passage; a fresh air inlet is arranged in the box body and above the fresh air passage; a fresh air outlet is arranged in the box body and below the fresh air passage; the heat pipe is arranged in the fresh air passage; the waste gas inlet of the oil removing and collecting energy-saving device is communicated with a waste gas port of the dryer; and the fresh air outlet of the oil removing and collecting energy-saving device is communicated with an air inlet of the dryer. Due to the adoption of the technical scheme, the adverse impact of oil substances in waste gas on a 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 a dryer with an energy-saving and purification-integrated design of an oil-collecting and energy-saving device. 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 current energy-saving devices ignore the impact of oily substances in the exhaust gas on the heat exchange surface of he...
