Abstract

The invention discloses a rectification device for ultra-pure ammonia with low energy consumption, which includes a raw material tank and a total condenser, a centrifugal pump is connected to the right end of the raw material tank, and an electric heating device is installed in the equidistant engagement connection inside the preheater plate, the left end of the preheater is connected with a tower body, the inner lower end of the tower body is provided with a blanking plate, the lower end of the left end surface of the tower body is connected with a first connecting pipe, and the inner left side of the tower kettle A reboiler is provided throughout, the upper surface of the tower kettle is connected with a second connecting pipe, the upper end of the tower body is connected with gas outlet pipes at equal intervals, the total condenser is connected to the upper end of the gas collection chamber, the A cold water pipe is arranged inside the refrigeration cavity. The ultra-pure ammonia low-energy rectification equipment has high mass transfer efficiency, which makes the rectification effect better. The flow detection and temperature detection devices are convenient to understand the situation and degree of distillation. There is a surplus recovery treatment device, temperature control device and The effect of the condensing device is faster, and the ammonia gas is accurately separated and purified.

Description

technical field [0001] The invention relates to the technical field related to rectification equipment, in particular to an ultra-pure ammonia low-energy rectification equipment. Background technique [0002] With the rapid development of my country's solar photovoltaic industry and semiconductor light-emitting devices, the demand for ultra-pure ammonia will increase significantly, but the domestic production level of ultra-pure ammonia is still relatively backward, requiring a lot of calculations and experimental research , the developed energy-saving refining process technology, so that not only can obtain qualified high-purity ammonia gas, but also have a great energy-saving effect, such as the development of science and technology and the increasing social demand for electronic products, new energy-saving lighting devices, and clean energy. The demand for high-purity ammonia is also increasing. [0003] For example, in the production of high-brightness LED devices, due to...

Problems solved by technology

[0004] The object of the present invention is to provide a rectification equipment with low energy consumption for ultra-pure ammonia, to solve the problem that the contact area between the liquid phase and the countercurrent gas phase under the action of the gravity field is small, and the efficiency of mass transfer is low, which makes the rectification process difficult. The effect of distillation is poor, and the water content is high; there is no flow detection and temperature detection device, it is inconvenient to know the situation and degree of distillation; there is no recovery and treatment device for surplus, which makes the utilization rate of ammonia gas low, and the temperature control device And the effect of the condensing device is slow, and the fixed temperature cannot be reached in time and accurately, so that the problem of accurate separation and purification of ammonia gas
