Description

Technical Field

[0001] The utility model relates to the technical field of diesel generator sets, in particular to a smoke elimination component of a diesel generator set. Background Art

[0002] During the operation of diesel generator sets, especially during startup and load changes, black smoke, blue smoke or white smoke may be generated. This is caused by incomplete combustion, oil combustion or water vapor emission. In order to reduce or eliminate these fumes, the existing technology often achieves the purpose of smoke elimination by setting up multi-layer filter plates.

[0003] For example, the Chinese patent application number CN202120950409.5 discloses a noise reduction and smoke removal device for a diesel generator set, comprising a base plate, the top of which is fixedly provided with a generator set housing, which is provided with a connecting block, a fixing rod, a stopper, a first filter plate, and a second spring, which presses the first filter plate downward. After the first filter plate is released, the first filter plate is pushed out under the elastic deformation of the second spring. This method filters the waste smoke generated by the diesel generator set, preventing the waste smoke from being discharged into the air and polluting the environment. At the same time, it is easy to replace the filter plate and ensure the filtering effect of the filter plate. However, smoke elimination only through the filter plate method requires frequent replacement. If the replacement is not timely, exhaust blockage is likely to occur, resulting in increased back pressure of the diesel generator set. Utility Model Content

[0004] In view of this, the purpose of the present invention is to propose a smoke elimination component for a diesel generator set to solve the technical problem that the existing technology only eliminates smoke through filter plates, which needs to be replaced frequently. Once the replacement is not handled in time, exhaust blockage is likely to occur, resulting in increased back pressure of the diesel generator set.

[0005] Based on the above purpose, the utility model provides a diesel generator set smoke suppression assembly, comprising a base plate and a generator set housing provided on the base plate, a heat dissipation protective shell further provided on the base plate, the heat dissipation protective shell being in communication with the generator set housing, a sealing plate being detachably mounted on the side end of the heat dissipation protective shell, and the smoke suppression assembly further comprising:

[0006] A smoke suppressor is provided in the heat dissipation protective shell. The interior of the smoke suppressor is a stepped structure. A gap flow channel is provided between the smoke suppressor and the heat dissipation protective shell. A smoke exhaust pipe is also provided at the top of the smoke suppressor;

[0007] Filter covers, there are a plurality of filter covers, and the plurality of filter covers are arranged inside the smoke elimination tube;

[0008] A spray barrel, the spray barrel being mounted on the inner top wall of the smoke elimination barrel via a fixing seat, and a water inlet pipe being provided on the top of the spray barrel;

[0009] A drainage pipe is installed at the lower part of the smoke elimination tube, and the drainage pipe is connected with the gap flow channel.

[0010] Furthermore, a filter plate is provided in the middle of the filter cover, and the filter cover has a trumpet-shaped structure.

[0011] Furthermore, the trumpet-shaped structure of the filter cover faces the smoke inlet direction of the generator set casing.

[0012] Furthermore, a guide groove is provided on the inner wall of the trumpet-shaped structure of the filter cover, and the lower end of the guide groove extends to the gap flow channel.

[0013] Furthermore, the spray cylinder is placed between two adjacent filter covers.

[0014] Furthermore, the lower end of the spray barrel is a curved structure, and a plurality of spray heads are evenly distributed on the lower end of the spray barrel.

[0015] The beneficial effects of the present invention are as follows: a diesel generator set smoke elimination component of the present invention is adopted. When in use, the waste smoke will pass through each filter cover in turn to complete gradual filtration and smoke elimination. At the same time, after water is supplied through the water inlet pipe, it forms a spray with the conversion of the spray barrel, so that a water mist environment is formed between each filter cover in the smoke elimination barrel, thereby achieving exhaust gas cooling while increasing the surface wettability of particles in the exhaust gas, making it easier to capture the filter cover, that is, accumulating and adhering to the surface of the trumpet-shaped structure of the filter cover to flow to the gap flow channel, and finally the sewage is discharged from the drain pipe, and the waste smoke after smoke elimination and cooling treatment is discharged through the exhaust pipe, avoiding the exhaust blockage, and having a good smoke elimination effect.
