Device for purifying diesel engine pulses and extracting high-quality nano graphene carbon granules

Abstract

The invention relates to the field of internal combustion engine tail gas treatment and nano graphene carbon granule extraction, and in particular to a device for purifying diesel engine pulses and extracting high-quality nano graphene carbon granules. The device comprises a gas inlet pipe, a gas inlet silencer, a DOC catalytic unit, a gas flow baffle, a primary stainless steel filter element,a secondary stainless steel filter element, carbon granule collectors and a gas outlet pipe, wherein the gas flow baffle is located between the DOC catalytic unit and the primary stainless steel filter element; and the carbon granule collectors are arranged at the lower parts of the primary stainless steel filter element and the second stainless steel filter element. A pulse electromagnetic valve is arranged between a pulse gas pipe and an air compressor gas tank; and the pulse electromagnetic valve is controlled by a pulse controller. The stainless steel filter elements have the characteristics of being free of blockage, high temperature-resistant, corrosion-resistant and easy to clean and extracting nano graphene; and the filter elements do not need to be dismounted for maintenance, so thatthe using is convenient and the using rates of mechanical vehicles are improved.

Description

technical field [0001] The invention relates to the field of exhaust gas treatment of internal combustion engines, in particular to a diesel internal combustion engine pulse purifier and high-quality nano-graphene carbon particles. Background technique [0002] With the continuous development of China's economy, the requirements for environmental protection are getting higher and higher. At present, the internal combustion engine is a wide range of mechanical driving power, which also brings about the problem of exhaust emissions. The existing diesel engine exhaust technology treatment adopts the form of DOC+DPF. This form of treatment has the problem that it is easy to cause clogging, and it needs to be removed for maintenance or replacement after clogging. For diesel engines with a large amount of black smoke, especially diesel engines used in construction machinery, due to poor operating conditions, frequent and rapid acceleration of the throttle will result in a large ...

AI Technical Summary

Problems solved by technology

This form of treatment has the problem that it is easy to cause clogging. After clogging, it needs to be removed for maintenance or replacement.

For diesel engines with a large amount of black smoke, especially diesel engines used in construction machinery, due to poor operating conditions, frequent and rapid acceleration of the throttle will result in a large amount of black smoke, which can easily completely block the DPF

With this technology, it usually takes a few days or even a few hours to remove the DPF for maintenance. If there is no timely maintenance, a strong back pressure will be formed to make the DPF interception carrier shift and cause damage to the DPF interception carrier. It is difficult to achieve real emission reduction. Moreover, DPF maintenance takes a lot of time, which leads to low utilization rate of vehicles and affects the overall economic benefits
