Abstract

The present invention relates to a condensing recovery equipment of harmful gas, which is characterized by connecting a condensing treatment barrel between existent drawing pipeline and exhausting pipeline to condense harmful gas to attain the goal of recovering and utilizing it. It is simple in structure and low in cost, its recovery rate can be up to 50-82%.

Description

Harmful gas condensing filter

The present invention relates to a kind of condensation retracting device of pernicious gas.

At present, China has the producer of a lot of manufacturings such as insulating materials, enamel-covered wire need use industrial chemicals such as alcohol, toluene, acetone in production process to make diluent, but above-mentioned industrial chemicals is volatile come out in drying course, if producer handles preferably to it and allow it directly be discharged in the air, will cause the pollution to surrounding enviroment, people's is healthy near the influence.

The object of the present invention is to provide a kind of condensation retracting device that can effectively reclaim pernicious gases such as toluene, acetone.

The objective of the invention is to realize: harmful gas condensing filter by following approach, it comprises air draft pipe and exhaust duct, the air outlet by the control of air channel gate is installed in the upper end of air draft pipe, be communicated with the condensation process tube between air draft pipe and the exhaust duct, this condensation process tube is skewed, its end position by air draft pipe is higher than the end by exhaust duct, the bottom of condensation process tube is provided with the liquids recovery mouth, the heat insulation sun layer is arranged on the skin of condensation process tube, be provided with water cavity between the inner tube wall of skin and condensation process tube, in the condensation process tube condenser pipe is installed, water cavity and condenser pipe communicate with water circulation system respectively, condenser pipe in the above-mentioned condensation process tube is divided into variform two sections, one section tower shape in the shape of a spiral, another section is the curved condenser pipe of layered arrangement, is fitted with screen pack in each gap between the curved condenser pipe of stratiform.Condensation process tube and horizontal angle are-10 °-10 °.Screen pack becomes with the resistance silk weaving, the mesh-density difference of each screen pack, this resistance wire directly and supply unit join, condenser pipe joins by power transformer unit and supply unit.

The present invention's cost simple in structure is low, the rate of recovery to pernicious gas reaches 50-82%, compare with general condensing unit, because this device can be removed the foreign material that are bonded in device inside easily by switching on, therefore, this device can increase substantially cooling effect and organic efficiency, and has alleviated labour intensity greatly, economic benefit and social benefit are all fine, are a kind of desirable pernicious gas treating apparatus.

Below in conjunction with accompanying drawing the present invention is described in further detail:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the structural representation of the curved condenser pipe 3 of the present invention;

Fig. 3 is the front view of the curved condenser pipe 3 of the present invention;

Fig. 4 is the vertical view of the curved condenser pipe 3 of the present invention;

Fig. 5 is the left view of the curved condenser pipe 3 of the present invention;

Fig. 6 is the structural representation of screen pack 4 of the present invention.

As shown in Figure 1, harmful gas condensing filter of the present invention, it is to be communicated with condensation process tube 30 between existing air draft pipe 1 and exhaust duct 16, this condensation process tube 30 is skewed, this condensation process tube 30 is 8 ° with horizontal angle, condensation process tube 30 is provided with liquids recovery mouth 26 by the bottom of an end of exhaust duct 16, is used to reclaim the liquid after condensation process; On the skin 9 of condensation process tube 30 heat insulation sun layer 25 is arranged, 7 of the inner tube walls of skin 9 and condensation process tube 30 have water cavity 8, be connected with condenser pipe 3 in the condensation process tube 30, water cavity 8 and condenser pipe 3 all play a part pernicious gas is carried out condensation, as Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, condenser pipe 3 wherein is divided into variform two sections, one section tower shape in the shape of a spiral, another section is the curved condenser pipe of layered arrangement, and these two sections condenser pipes, 3 water loop heads join with two arms of water inlet pipe 5 respectively.Its water loop exit links to each other with outlet pipe 6 by arm, above-mentioned water inlet pipe 5 and the outlet pipe 6 formation circulation waterway that communicates with pipeline in the recirculated water refrigerating plant 11 that utilizes floride-free compressor cooling, for water is circulated in pipeline, the water pump 2 that draws water is installed on water inlet pipe 5, consider the life problems of condenser pipe, Xun Huan water is soft water within it.

The water-cooled of this device has two lines: one is that current flow into condenser pipe 3 from water inlet pipe 5, flows back to recirculated water refrigerating plant 11 through outlet pipe 6; Another is after current flow into water cavity 8 from water inlet pipe 5, to flow into condenser pipe 3 again, flows back to recirculated water refrigerating plant 11 through outlet pipe 6.

Be fitted with screen pack 4 in each gap between the curved condenser pipe of above-mentioned stratiform, its structure as shown in Figure 6, this screen pack 4 is to be bonded and fixed on the stainless steel insert 32 by high-temperature insulation ceramic block 31, the asbestos board 33 of heatproof insulation connects into an integral body with stainless steel insert 32, and be made into net with resistance wire 10 thereon, this resistance wire 10 and condenser pipe 3 all join with supply unit 17, treat on resistance wire 10 and the condenser pipe 3 that sticking foreign material too much and have influence on when reclaiming benefit, can start supply unit 24, to its energising, thereby utilize high temperature that foreign material are disposed.In order to improve the effect of filtration, the mesh-density of each adjacent screen pack 4 is neither together.

In order to maintain conveniently, the air outlet 18 by 19 controls of air channel gate is installed in the upper end of air draft pipe 1, and this air outlet 18 is closed during operate as normal, treats then can open after condensing unit breaks down air outlet 18 and continues to produce.

The production process of harmful gas condensing filter of the present invention is as follows: the waste gas that contains pernicious gas enters condensation process tube 30 from air draft pipe 1, the dual-cooled effect of the water cavity 8 by these condensation process tube 30 barrels and the condenser pipe 3 of interior dress thereof, above-mentioned pernicious gas can become liquid state, flow out from liquids recovery mouth 26 along the condensation process tube 30 that tilts, contain container and get final product.
