Abstract

The invention relates to a pressurized type liquid ammonia filtration system connection device for nitric acid production. The device comprises a filtration pipe, the upper end of the filtration pipeis provided with a pressurizing branch chain, the lower end of the filtration pipe is provided with a filtration branch chain, and the front end of the filtration pipe is provided with a connection branch chain. The device can solve the following problems of liquid ammonia filtration in a current nitric acid process: a, manual work is required for enabling liquid ammonia to be conveyed into a filtration machine with the help of current equipment, the operation is complex, the liquid ammonia needs to be sealed during conveying operation to prevent the liquid ammonia from volatilizing into air to cause environmental pollution, the labor intensity is great, and potential safety hazards exist, and b, a current filtration machine is slow in filtration rate, consumes long time and influences theefficiency of nitric acid manufacture and production, and the current filtration machine is troublesome in disassembly and high in maintenance cost, and increases the cost of nitric acid production.

Description

technical field [0001] The invention relates to the technical field of liquid ammonia filtering equipment, in particular to a connection device for a pressurized liquid ammonia filtering system for nitric acid production. Background technique [0002] Liquid ammonia is one of the main raw materials for making nitric acid. Liquid ammonia needs to be filtered in the process of making nitric acid. The liquid ammonia filtration process directly affects the cost and quality of nitric acid. [0003] However, the following problems exist in the filtration of liquid ammonia in the existing nitric acid process. a. It is necessary to manually transfer the liquid ammonia to the filter machine with the help of existing equipment, which is complicated to operate. The air causes environmental pollution, labor intensity is high, and there are potential safety hazards. b. The existing filtration machine has a slow filtration speed and takes a long time, which affects the efficiency of nitri...
