Description

A diesel generator exhaust gas treatment device

Technical Field

The utility model relates to the technical field of diesel generators, in particular to an exhaust gas treatment device for a diesel generator.

Background Art

A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. The common diesel generator among generators is a small power generation equipment that uses diesel as fuel and generates electricity through a diesel engine. Since the exhaust gas emitted by a diesel engine during operation pollutes the environment greatly, a treatment device is needed to treat the exhaust gas before discharging it.

A common diesel generator exhaust gas treatment device is composed of a housing, a suction fan, a filtering structure (such as a filter screen, an activated carbon plate, etc.), an air intake pipe, and an exhaust pipe. The suction fan and the air intake pipe suck the exhaust gas of the diesel generator into the housing, and process it through the filtering structure, and then discharge the treated gas to the outside through the exhaust pipe. This is the common structure and use of the exhaust gas treatment device of a diesel generator. In traditional diesel generator exhaust gas treatment devices, since the exhaust gas discharged by the diesel generator has a high temperature, if it directly contacts the filter screen, it will cause aging or deformation of the filter screen material, reducing its filtering effect. Some diesel generator exhaust gas treatment devices, by adding a spray structure inside, spray liquid on the incoming high-temperature exhaust gas, thereby achieving the effect of cooling the high-temperature flue gas. However, in this way, the diesel generator exhaust gas contains oil and gas, which is cooled to form a liquid and mixed with the liquid, resulting in the cooling liquid cannot be reused, and it is not convenient for separation and treatment. For this reason, a diesel generator exhaust gas treatment device is proposed.
