Collected oil removing and energy saving device for setting machine

Abstract

The invention discloses a collected oil removing and energy saving device for a setting machine. The collected oil removing and energy saving device comprises a box body, wherein the inside of the box body is divided into a waste gas channel and a fresh air channel; a filter screen, a lower collected oil removing device, heat tubes and an upper collected oil removing device are sequentially arranged in the waste gas channel from bottom to top; and the heat tubes are arranged in the fresh air channel. The heat tubes are straight tubes in which heat transfer media are closed; and the heat tubesare arranged in an array manner. The upper collected oil removing device and the lower collected oil removing device respectively comprise an upper arched plate, a distance rod and a lower arched plate; the upper arched plate and the lower arched plate are vertically and alternately arranged to be corrugated in a concave-convex alternative manner; the upper arched plate and the lower arched plateare locally overlapped at two sides of a chambered surface; and a clearance is formed between the upper arched plate and the lower arched plate so that waste gas can flow in the clearance. Inclined angles of 5-15 degrees are respectively formed between the upper collected oil removing device and a horizontal plane as well as between the lower collected oil removing device and the horizontal panel; an upper oil collecting groove and a lower oil collecting groove are respectively arranged at the lower inclined end bottom part of the upper collected oil removing device and the lower inclined endbottom part of the lower collected oil removing device; and an upper oil overflow pipe and a lower oil overflow pipe are respectively arranged at the bottom of the upper oil collecting groove and thebottom of the lower oil collecting groove. According to the technical scheme of the invention, the negative influence on a heat exchange surface caused by oily substances in waste gas 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...
