Heavy water recovery device of deuterium gas generator

Abstract

The invention provides a heavy water recovery device of a deuterium gas generator. The heavy water recovery device of the deuterium gas generator comprises a collecting box and a cooling box, the cooling box is fixedly arranged on the collecting box, a condensation pipe is arranged in the cooling box in a penetrating mode, the condensation pipe communicates with the collecting box through a liquid collecting pipe, a circulating pump used for water circulation is arranged on the cooling box, a heat exchanger is installed on the outer side wall of the collecting box, the circulating pump is connected with the heat exchanger, a scraping mechanism used for scraping a water film gathered on the inner wall of the condensation pipe is arranged on the condensation pipe, and a driving mechanism used for promoting water circulation and driving the scraping mechanism is arranged in the cooling box. The heavy water recovery device of the deuterium gas generator is exquisite and reasonable in structural design, high in practicability and capable of guaranteeing circulating flow of water flow, improving the gas condensation effect, improving the gas recovery efficiency and increasing the resource utilization rate.

Description

technical field [0001] The invention belongs to the technical field of deuterium gas preparation, and in particular relates to a heavy water recovery device for a deuterium gas generator. Background technique [0002] Deuterium is a colorless, odorless, non-toxic flammable gas that can be used to produce heavy hydrogen-containing compounds in the fields of chemistry and biochemistry. Deuterium generators are common equipment for preparing deuterium. [0003] The deuterium gas generators in the prior art are usually equipped with single- and double-circulation electrolyzers, and the gas electrolyzed by the device contains a large amount of heavy water vapor, which is condensed into heavy water after passing through the condenser, so as to realize the recovery of heavy water, but in practice In the process of use, when the gas from electrolysis passes through the condenser tube, due to the limited heat transfer area and cooling speed of the condenser tube, the cooling efficien...

Problems solved by technology

[0003] The deuterium gas generators in the prior art are usually equipped with single- and double-circulation electrolyzers, and the gas electrolyzed by the device contains a large amount of heavy water vapor, which is condensed into heavy water after passing through the condenser, so as to realize the recovery of heavy water, but in practice In the process of use, when the gas from electrolysis passes through the condenser tube, due to the limited heat transfer area and cooling speed of the condenser tube, the cooling efficiency of the gas is relatively low, resulting in part of the gas passing through the condenser tube before being liquefied, resulting in Secondly, part of the gas will form a layer of water film on the inner wall of the condenser tube, and adhere to the inner wall of the condenser tube. This layer of water film cannot condense into water droplets and fall under the action of surface tension, which will also cause The waste of gas makes it difficult for the device to fully recover heavy water. Therefore, it is necessary to design a deuterium generator heavy water recovery device to solve the above problems
