Problems solved by technology

[0003] The current mainstream DPF regeneration system in the market includes combustion type, pure passive, and tailpipe rear injection type, etc. However, special non-road vehicles such as small forklifts cannot be installed with a combustion type DPF system based on the combustion chamber structure due to their small space. Its original row is relatively large, and the pure passive system is very easy to block, while its exhaust temperature is low and it starts and stops frequently, so the tailpipe rear injection system cannot be used

Abstract

The invention discloses an electric heating DPF control device and relates to the technical field of diesel tail gas treatment. The electric heating DPF control device comprises a heating cavity, a control cabinet and a diesel particulate filter. A heating tube and a temperature sensor are mounted in the heating cavity. A controller, an indicator lamp and a display device are mounted in the control cabinet. A power grid supplies power to the control cabinet and the heating tube. The temperature sensor is connected with the controller through a signal line. The gas outlet end of the heating cavity is connected with the diesel particulate filter. The electric heating DPF control device is simple in structure, small in size and capable of being mounted on special non-road vehicles such as small forklifts. The control device is uniform and precise in heating temperature, the corresponding calibration can be conducted according to the actual vehicle conditions, and the applicability and stability of a DPF regeneration system can be enhanced.

Description

Technical field [0001] The present invention relates to the technical field of diesel engine exhaust gas treatment, in particular to an electric heating DPF control device. Background technique [0002] Particulate filter, also known as diesel particulate filter (DPF), is currently recognized as the most effective diesel particulate aftertreatment technology. The particulate trap regeneration technology and its regeneration can only filter particulates from the exhaust of diesel engines and deposit them in the filter element. It cannot remove particulates by itself. The particles accumulated in the DPF will gradually increase the flow resistance of the exhaust, increase the exhaust back pressure of the diesel engine, affect the ventilation and combustion of the diesel engine, reduce the power output, and increase the fuel consumption. Therefore, the particles accumulated in the DPF must be cleared in time to restore the low resistance close to the original. This process is calle...
