Air exhausting white smoke eliminating device for setting machine

Abstract

The invention discloses an air exhausting white smoke eliminating device for a setting machine. The air exhausting white smoke eliminating device for the setting machine is characterized by comprisinga heat exchanging channel; the upper end of the heat exchanging channel is connected with a first pipeline and a second pipeline; the lower end of the heat exchanging channel is connected with a third pipeline and a fourth pipeline; an exhausting port of the first pipeline and a gas inlet of the second pipeline communicate with each other through the heat exchanging channel; and an exhausting port of the second pipeline and a gas inlet of the third pipeline communicate with each other through the heat exchanging channel. Compared with the prior art, according to the air exhausting white smokeeliminating device for the setting machine, clean-state gas discharged after treatment by an environment protecting device performs heat exchanging with high-temperature gas discharged out of a production line in a vent plate; and due to the method, the exhausting temperature can be achieved and cost is saved for enterprises under a common condition without any auxiliary heating devices.

Description

technical field [0001] The design of the present invention relates to the field of environmental protection equipment manufacturing, and specifically refers to a device for eliminating white smoke from exhaust air of a setting machine. Background technique [0002] At present, the effect of wet electrostatic dust removal is better for the exhaust emission of environmental protection equipment in the printing and dyeing baking furnace process line, but there is obvious white smoke phenomenon in the exhaust. Some manufacturers add a heat exchanger after the dust removal equipment, use steam or steam condensed water to heat, and heat the exhaust gas with saturated humidity after the environmental protection equipment to exceed the dew point temperature by at least 20°C, so that the relative temperature of the exhaust gas is much lower than the ambient state. At the moment when the discharge port mixes with the atmosphere, there is no time for the temperature drop to condense, a...

AI Technical Summary

Problems solved by technology

[0002] At present, the exhaust gas emission of environmental protection equipment in the printing and dyeing baking furnace process line adopts wet electrostatic dust removal, which has a better effect, but the exhaust gas has obvious white smoke phenomenon.

Some manufacturers add a heat exchanger after the dust removal equipment, use steam or steam condensed water to heat, and heat the exhaust gas with saturated humidity after the environmental protection equipment to exceed the dew point temperature by at least 20°C, so that the relative temperature of the exhaust gas is much lower than the ambient state. At the moment when the discharge port mixes with the atmosphere, there is no time for the temperature drop to condense, and then the diffusion will never condense, and there will be no suspicion of emitting polluting gases. Some manufacturers may even be required to install expensive online detection equipment. troubled

[0003] At present, many production line equipments have progressed to use natural gas as heat energy and use steam to eliminate white smoke, but this method will undoubtedly greatly increase the cost of enterprises
