Embodiment 1

[0029] Exhaust gas treatment systems for fuel trains in the prior art are usually single-channel, and a purification unit for purifying exhaust gas is arranged in the channel. The purification channel of the exhaust gas treatment system for fuel trains with this structure is extremely easy to be blocked by particles in the exhaust gas, and The treatment effect on the soot in the exhaust gas is poor, and the maintenance cycle of the exhaust gas treatment system for fuel trains is relatively short.

[0030] In view of the above technical problems, embodiment 1 provides an exhaust gas treatment system for fuel trains, such as figure 1 As shown, it includes: engine ignition switch 02, engine speed detector 03, exhaust processor 01 and human-computer interaction system 04.

[0031] The exhaust processor 01 includes an exhaust inlet 1 and an exhaust outlet 2; a main passage 3, a first bypass 4 and a second bypass 5 are arranged between the exhaust inlet 1 and the exhaust outlet 2, and...

Embodiment 2

[0058] Embodiment 2 also provides a control method for a fuel train tail gas treatment system, using the fuel train tail gas treatment system of embodiment 1, such as figure 1 shown, including:

[0059] Start-up phase (within 5 to 15 seconds after the engine starts): the control unit 7 receives "the engine ignition switch 02 is turned on, and the speed data of the engine speed detector 03 is less than the first threshold", and the control unit 6 controls the first bypass valve 002 is opened, the main passage valve 001 is closed, and the second bypass valve 003 is closed; at this time, the first bypass 4 is connected, and the main passage 3 and the second bypass 5 are closed. When the fuel train engine is just started, the exhaust gas with high concentration of particulate matter (PM) directly passes through the first bypass 4, and under the action of the diesel particulate filter (DPF) 40, the particulate matter (PM) in the exhaust gas is filtered and captured, which can signi...

Abstract

The invention relates to the field of fuel trains, in particular to a tail gas treatment system for a fuel train and a control method of the tail gas treatment system. The tail gas treatment system comprises an engine ignition switch, an engine rotating speed detector, a tail gas treatment device and a man-machine interaction system. The tail gas treatment device is provided with a main passage, a first bypass and a second bypass which are connected in parallel. The main passage is provided with a diesel catalytic oxidizer and a particulate matter oxidizer. The first bypass is provided with a diesel particulate filter. The second bypass is a straight-through bypass. Valves are arranged at the inlet end of the main passage, the inlet end of the first bypass and the inlet end of the second bypass. The man-machine interaction system comprises a display unit and a control unit. The engine ignition switch, the engine rotating speed detector, the main passage valve, the first bypass valve, the second bypass valve and the display unit are all electrically connected with the control unit. According to the tail gas treatment system for the fuel train and the control method of the tail gas treatment system, the operation condition of an engine is recognized through the man-machine interaction system on the basis of the state parameters of the engine ignition switch and the engine rotating speed detector, and the tail gas processor is adjusted according to the operation condition.

Description

technical field [0001] The invention relates to the technical field of fuel trains, in particular to an exhaust gas treatment system for fuel trains and a control method thereof. Background technique [0002] Fuel trains are usually driven by diesel engines with large exhaust emissions. Especially when the engine of the fuel train is just started, because the combustion conditions are not optimal, the fuel combustion is not sufficient, and the concentration of particulate matter (PM) in the exhaust gas is relatively high. [0003] Exhaust gas treatment systems for fuel trains in the prior art are usually single-channel, and a purification unit for purifying exhaust gas is arranged in the channel. The purification channel of the exhaust gas treatment system for fuel trains with this structure is extremely easy to be blocked by particles in the exhaust gas, and The treatment effect on the soot in the exhaust gas is poor, and the maintenance cycle of the exhaust gas treatment s...
