Abstract

The invention provides a multi-temperature-range composite halide ammonia storage tank structure with a temperature range self-adaption function. The multi-temperature-range composite halide ammonia storage tank structure comprises an ammonia storage tank and a flue gas channel. The ammonia storage tank comprises a tank body shell (15) and unit pipes, and one or more unit pipes are arranged in theinner space of the tank body shell (15) in a penetrating manner. The flue gas channel comprises a flue gas inlet pipeline (1), a flue gas main pipeline upstream segment (2), flue gas branch pipes (19), a flue gas main pipeline downstream segment (9) and a flue gas outlet pipeline (10) which are connected in sequence. The flue gas branch pipes (19) are arranged in the unit pipes in a penetrating manner and are in one-to-one correspondence to the unit pipes. The space between the unit pipes and the flue gas branch pipes (19) is filled with an adsorption agent (11). According to the multi-temperature-range composite halide ammonia storage tank structure, the solid adsorption agent is adopted for storing ammonia gas, the problems of nozzle blocking, crystallizing and freezing generated by traditional urea solution ammonia storage are avoided, the manner of driving ammonia gas desorption through flue gas waste heat is adopted as the main manner, the problem of energy consumption of electric heating and circulating fluid heating of a traditional ammonia storage tank is avoided, and the complementary energy utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of automobile tail gas treatment and adsorption, in particular to a multi-temperature domain compound halide ammonia storage tank structure with temperature domain self-adaptive function. Background technique [0002] Nitrogen oxide is a poisonous gas that has great harm to the human body. At the same time, it is an environmental pollutant that forms acid rain, photochemical pollution, and destroys the structure of the ozone layer. Heavy-duty diesel engine vehicles are the main source of nitrogen oxide emissions. For the sustainable development of human beings, it is imperative to meet the challenges of energy and the environment and solve the problem of vehicle exhaust emissions. In the automobile exhaust gas treatment system, ammonia gas is used as the reducing agent of nitrogen oxides, and its storage and supply problems have been paid more and more attention by researchers. [0003] At present, ammonia ...
