ANG transport cart

Abstract

The invention discloses an ANG transport cart, and relates to the field of natural gas storage and transport devices. The ANG transport cart comprises a transport cart body and an ANG tank body which is fixed to the transport cart body and filled with adsorbent. The key is that an inflation and deflation pipeline is arranged in the 1/6-1/3 height position, inside the ANG tank body, of the ANG tank body, and extends to end sockets on two sides of the ANG tank body in the axial direction of the ANG tank body. A heat exchange pipeline is wound outside the inflation and deflation pipeline and connected with a heat exchange system of the transport cart body. The ANG transport cart has the beneficial effects that the stability of heat in the adsorption and desorption process of the natural gas is guaranteed through a heat exchange mode, the whole transport cart forms a relatively independent system, and other external equipment is not needed; even in the adsorption process, the water in the heat exchange pipeline is cold water, and the heat exchange pipeline wound on the inflation and deflation pipeline cools the inflated natural gas and the adsorbent; and in the deflation process, the water in the heat exchange pipeline is warm water, and the adsorption and desorption efficiency of the adsorbent is guaranteed.

Description

technical field [0001] The invention relates to the field of natural gas storage and transportation devices, in particular to an ANG transport vehicle for storing and transporting natural gas. Background technique [0002] At present, natural gas storage and transportation methods mainly include compressed natural gas (CNG), liquefied natural gas (LNG) and adsorbed natural gas (ANG). Among them, compressed natural gas is mostly transported in tube-bundle containers under relatively high pressure (20MPa); liquefied natural gas is transported in the form of low-temperature tank cars. The above two storage and transportation methods have been used in large-scale industrial applications, and ANG is a special adsorbent for natural gas with a high specific surface in the storage tank. Using its huge specific surface area and rich microporous structure, it can be used at room temperature and medium pressure (3 ~6MPa) to achieve a storage capacity close to that of CNG, and has the ...

AI Technical Summary

Problems solved by technology

Cooling water and circulating water are introduced into the natural gas charging and degassing process to alleviate the thermal effect of adsorption, but it needs to set up circulating water supply equipment at the natural gas adsorption site and desorption site, which increases the cost and the difficulty of popularization and use. Conducive to the development of ANG transportation
