A diesel engine high temperature exhaust gas filter device

Abstract

The invention discloses a diesel engine high-temperature exhaust gas filtering device, which comprises a conveying pipe, a motor and a filter screen. The pipes intersect, and the filter screen vertically passes through the slits on the conveying pipes. There are high-pressure air nozzles on the outside of the slits, and a protective layer is provided on the inner side of the joint between the conveying pipes and the filter screen. The width of the filter screen is larger than the diameter of the protective layer and smaller than the diameter of the conveying pipes. , the corner of the protective layer closest to the filter screen is provided with a guide angle, and a cleaning pipe is provided under the motor. The structure of the invention is simple, and the high-temperature exhaust gas is filtered, cooled, and cleaned through the continuously rotating filter screen, and the filtration speed is accelerated. Harmful substances in the exhaust gas are filtered out and can be directly discharged outdoors without causing environmental problems. The filter device has low cost, simple operation, long service life, thorough purification, low energy consumption, energy saving and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of industrial exhaust gas filtering devices, and in particular relates to a high-temperature exhaust gas filtering device for diesel engines. Background technique [0002] In diesel engine manufacturing enterprises, the test workshop is a workshop that will test the performance of the machine. When working, because many diesel engines work together, a lot of exhaust gas is emitted, including nitrogen oxides, hydrocarbons, carbon monoxide, dust, solid particles and other harmful substances. At present, the requirements for the environment are getting higher and higher. Most enterprises have waste gas treatment devices, but the existing waste gas treatment devices have the following disadvantages: 1) The structure is complex, divided into reaction towers, cooling devices, treatment devices, etc., and the cost is high. The effect of exhaust gas filtration is not very good. Generally, only particulate matter or ...

Problems solved by technology

[0002] In diesel engine manufacturing enterprises, the test workshop is a workshop that will test the performance of the machine. When working, because many diesel engines work together, a lot of exhaust gas is emitted, including nitrogen oxides, hydrocarbons, carbon monoxide, dust, solid particles and other harmful substances. At present, the requirements for the environment are getting higher and higher. Most enterprises have waste gas treatment devices, but the existing waste gas treatment devices have the following disadvantages: 1) The structure is complex, divided into reaction towers, cooling devices, treatment devices, etc., and the cost is high. The effect of exhaust gas filtration is not very good. Generally, only particulate matter or harmful gas is filtered during exhaust gas filtration, and then discharged directly, resulting in that the filtered exhaust gas still cannot fully meet the standard; 2) The complete set of equipment is troublesome to replace and maintain. Replace the filter device, the harmful substances in the exhaust gas will be excessively captured, causing the filter device to block and reduce the effect; 3) The filtration efficiency is low and the discharge temperature is high. Therefore, an exhaust gas filter device that can solve the above problems is needed
