Self-heating-type solid ammonia filling device

Abstract

The invention discloses a self-heating-type solid ammonia filling device, which comprises an ammonia buffer tank, a heat exchanger and a solid ammonia filling tank. The ammonia buffer tank is connected with the connecting end of the heat exchanger, a filter is arranged at the output end of the ammonia buffer tank, the output end of the filter is connected with the input end of the solid ammonia filling tank, a cooling water sink is arranged at the connecting end of the heat exchanger, the output end of the solid ammonia filling tank is connected with the input end of the cooling water sink, and a liquid ammonia storage tank is arranged at the connection end of the ammonia buffer tank. In the solid ammonia filling process, when liquid ammonia is gasified, gasifying of the liquid ammonia needs a large amount of heat, and meanwhile, a large amount of heat is released in the process that solid ammonia adsorbs ammonia gas, the whole filling device is reasonably designed through a technology, equipment and energy consumption of gasifying the liquid ammonia are omitted, and meanwhile, the equipment and energy consumption of cooling of cooling water are omitted.

Description

technical field [0001] The invention relates to the field of ammonia filling devices, in particular to a self-heating solid ammonia filling device. Background technique [0002] In the post-treatment process of automobile exhaust, ammonia gas needs to be used for treatment. The ammonia gas needs to be adsorbed in the solid ammonia storage tank. During the solid ammonia filling process, the liquid ammonia needs to be gasified, separated, filtered, and pressure-regulated. The solid ammonia storage tank emits a large amount of heat during filling, and the tank body needs to be cooled. However, the heat emitted by the existing solid ammonia filling cannot be recycled, resulting in energy loss. Therefore, it is necessary to invent a self-heating type solid ammonia filling device to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a self-heating solid ammonia filling device to solve the problems raised in the above-m...

Problems solved by technology

[0002] In the post-treatment process of automobile exhaust, ammonia gas needs to be used for treatment. The ammonia gas needs to be adsorbed in the solid ammonia storage tank. During the solid ammonia filling process, the liquid ammonia needs to be gasified, separated, filtered, and pressure-regulated. The solid ammonia storage tank emits a large amount of heat during filling, and the tank body needs to be cooled down. However, the heat released by the existing solid ammonia filling cannot be recycled, resulting in energy loss.
