The invention discloses a natural gas adsorption storage device for natural gas automobiles, which comprises a degassing heating desorption system and an aeration cooling adsorption system, wherein the degassing heating desorption system comprises a high-temperature evaporator, a natural gas adsorption storage box, a condenser, a liquid storage device and a circulating pump; the aeration cooling adsorption system comprises a refrigeration compressor, the condenser, the liquid storage device, a thermostatic expansion valve and the natural gas adsorption storage box; a temperature sensing bag of the thermostatic expansion valve is arranged in an adsorption layer of the natural gas adsorption storage box; the degassing heating desorption system and the aeration cooling adsorption system share the condenser and the liquid storage device; and the high-temperature evaporator is heated by automobile exhaust in a heat convection mode. By the natural gas adsorption storage device, the problem of the influence of the temperature rise and temperature reduction of bed layers of adsorbents due to heat release and heat absorption in the adsorption-desorption process on adsorption storage capacity and desorption release capacity is solved, so that the adsorption and desorption processes are performed at a constant temperature all the time, and the performance of the adsorbents can be exertedto the maximum degree.
Description
technical field [0001] The invention relates to a gas storage technology for natural gas vehicles, in particular to a natural gas adsorption storage device for natural gas vehicles. Background technique [0002] With the increasing shortage of oil resources in the world, natural gas is becoming more and more popular due to its advantages of high calorific value and low pollution emission. It is a relatively abundant and clean alternative fuel for vehicles. Compared with gasoline, the main problem of natural gas as a vehicle fuel is its low volumetric energy density. How to safely, economically and effectively increase the energy density of natural gas on-board storage is the key to the development of natural gas vehicles. At present, natural gas can be stored in three ways: liquefaction, compression and adsorption. The liquefied natural gas method requires low-temperature cryogenics, which not only consumes high energy, but also is difficult to maintain during the storage ...
