Abstract

The invention relates to a connection device of a pressurized liquid ammonia filtration system for nitric acid production, comprising a filter tube, a pressurized branch chain is arranged at the upper end of the filter tube, a filter branch chain is arranged at the lower end of the filter tube, and a connecting branch chain is arranged at the front end of the filter tube. The present invention can solve the following difficult problems existing in the liquid ammonia filtration in the existing nitric acid process. Ammonia volatilizes into the air to cause environmental pollution, labor intensity is high, and there are potential safety hazards. b The existing filtering machine has a slow filtering speed and takes a long time, which affects the efficiency of nitric acid production. Moreover, the existing filtering machine is troublesome to disassemble, and the cost of maintenance and care is high. , Increase the cost of nitric acid production.

Description

Technical field[0001]The present invention relates to the technical field of liquid ammonia filtration equipment, and in particular, nitric acid production pressurized liquid ammonia filtration system connection means.Background technique[0002]Liquide ammonia is one of the main raw materials of nitric acid, and liquid ammonia needs to be filtered during the production of nitric acid, and the liquid ammonia filtration process directly affects the cost and quality of nitric acid.[0003]However, there is a problem in the existing nitric acid process, A, which requires manual use of existing equipment to deliver liquid ammonia to the filter machine, complex operation, and seal for liquid ammonia in delivery, avoid liquid ammonia Environmental pollution, high labor intensity, safety hazard, B existing filter machine filter is slow, time consumption, affecting the efficiency of nitric acid production production, and existing filtration machine disassemble trouble, maintenance and nitric ac...
