Technical Field

The invention relates to a medium and small-sized marine diesel engine, in particular to a water washing regeneration treatment device and a treatment method of an alloy carrier particle catcher (metal DPF filter screen for short) for purifying tail gas of the medium and small-sized marine diesel engine.

Background

The rapid development of modern industry brings many environmental problems while creating huge wealth for human society. Among them, the emission of diesel particulate has become one of the primary pollutants of the atmosphere. The river vessels in the river channels of economically developed regions such as Yangtze river basin, Zhujiang river basin and the like in China have high density and frequent navigation and operation, so that the harm of ship tail gas emission pollution is more serious. In order to prevent the problem of air pollution from further developing, China has been provided with a series of increasingly strict emission regulations such as 'implementation schemes of ship emission control areas in bead triangle, long triangle, Bohai sea (Jingjin Ji) water areas', 'implementation schemes of ship air pollutant emission control areas', 'emission limit values of ship engines in GB15097-2016 and measurement methods (first and second stages of China)' which show that the emission reduction and reconstruction of ship diesel engines in coastal areas and inland rivers are urgent.

Water wash regenerated alloy carrier particle traps (abbreviated as DPFs) are the latest DPF devices at present. The method has the characteristics of large carbon capacity, high treatment efficiency and water washing, regeneration and cleaning, has wider and wider application range, and is developed from the automobile field to the marine diesel engine field.

Disclosure of Invention

The invention aims to solve the technical problem of providing a metal DPF filter screen washing regeneration treatment device and a treatment method for small and medium-sized marine diesel engines, the device can quickly replace, clean, dry and treat waste water for the metal DPF filter screen, and has the advantages of convenience in disassembly and assembly, simplicity in maintenance, prevention of secondary pollution of sewage and the like.

The technical solution of the invention is as follows:

the utility model provides a metal DPF filter screen washing regeneration treatment device for middle-size and small-size marine diesel engine exhaust purification which characterized in that: the device comprises a cleaning and drying box body, wherein a plurality of round holes are formed in the top of the box body and used for fixing and placing the metal DPF filter screen, four sides of the box body are composed of a liftable inner wall and an outer wall, a high-pressure water gun is arranged on the inner wall, an electric heating drying device is arranged between the inner wall and the outer wall, a discharge port is arranged at the bottom of the box body and is connected with a wastewater treatment device through a connecting pipeline.

The metal DPF filter screen is arranged in a cylindrical shape, and the surface of the cover plate of the metal DPF filter screen is provided with a lifting bracelet.

The method for treating the metal DPF filter screen by using the metal DPF filter screen washing regeneration treatment device comprises the following steps:

1) the method comprises the following steps that a lifting bracelet is tightly held by two hands to take a cylindrical metal DPF filter screen to be treated out of a DPF device for tail gas purification of a small and medium-sized marine diesel engine, the metal DPF filter screen is placed into a box body from a round hole at the top of the box body and then fixed, a high-pressure water gun is started to clean carbon deposition captured on the metal DPF filter screen, after cleaning is completed, sewage is sent to a wastewater treatment device through a discharge port and a connecting pipeline to be subjected to wastewater treatment, and secondary pollution of the cleaned wastewater to a channel water area where a ship is located is prevented;

2) meanwhile, raising the inner wall, starting an electric hot air device, drying the metal DPF filter screen after a period of heating, and lowering the inner wall to the original position after drying;

3) both hands are tightly held and are carried the metal DPF filter screen after will drying again and put back middle-size and small-size marine diesel engine exhaust purification's DPF device in, all accomplish the replacement of metal DPF filter screen promptly, wash, dry and the waste water treatment operation after wasing.

Compared with the prior art, the invention has the following beneficial effects:

the invention provides a device for rapidly replacing, cleaning, drying and treating waste water for small and medium-sized marine diesel engines in inland waterway shipping, which needs to be provided with metal DPF filter screens, and can prevent secondary pollution. In the device, set metal DPF filter screen device to cylindric, set up at its apron surface and carry and draw the bracelet to conveniently carry out the replacement operation from the DPF device. The invention has the advantages of convenient disassembly and assembly, simple maintenance, prevention of secondary pollution of sewage and the like.

The device solves the difficult points that the metal DPF filter screen is not easy to replace, is fast cleaned and is fast dried after reaching the service life, and solves the problem of treating the sewage after cleaning.
