Solid ammonia replenishment system and vehicle with same

Abstract

The invention discloses a solid ammonia replenishment system which comprises an ammonia storage tank used for containing solid ammonia. The system further comprises a replenishment tank connected with the ammonia storage tank, a pressure sensor device and a control device. The replenishment tank is provided with a heating device. A connection pipeline for the replenishment tank and the ammonia storage tank is provided with a one-way valve allowing the replenishment tank to supply ammonia to the ammonia storage tank. The pressure sensor device is used for measuring gas pressure in the ammonia storage tank. The control device is connected with the pressure sensor device and used for controlling the heating device to work and open the one-way valve when the gas pressure in the ammonia storage tank is lower than a preset value. According to the system, ammonia compensation can be carried out on the ammonia storage tank by heating the ammonia replenishment tank, the ammonia replenishment tank can assist the ammonia storage tank in building pressure together, normal supply of ammonia is maintained within a certain period of time, normal work of a vehicle system is ensured, an ammonia device meets emission standards, and tail gas treatment quality is ensured. It is ensured that a vehicle can normally drive to a specified ammonia storage tank replacement service station for replacement. The invention further discloses a vehicle comprising the solid ammonia replenishment system.

Description

technical field [0001] The invention relates to the technical field of vehicle tail gas treatment, and more specifically relates to a solid ammonia ammonia supply system. In addition, the present invention also relates to a vehicle comprising the above-mentioned solid ammonia ammonia supply system. Background technique [0002] With the progress of the economy and society, the rapid development of the automobile industry, along with the sharp increase in the number of vehicles, the environmental pollution caused by vehicle exhaust is also becoming more and more serious. Therefore the purification problem of automobile tail gas, is subjected to people's attention day by day. [0003] The automobile exhaust gas treatment system stores ammonia gas in solid particles and releases it when needed, and removes NOx hazards after reacting with the catalyst to achieve the purpose of purifying the exhaust gas. The method is safe, reliable and low in cost. [0004] However, when the ...

Problems solved by technology

[0004] However, when the solid ammonia system is in the later stage of use, because the user does not replace the ammonia storage tank in time, the ammonia storage tank will have insufficient gas pressure, or the pressure will soon meet the exhaust gas treatment pressure value, so a compensating tank is required to supplement the reducing agent to support the solid ammonia. The system maintains standard exhaust gas treatment, so that the vehicle can run normally, and the ammonia storage tank can be replaced at the designated replacement service station
