Title:
PRIMARY COOLING PROCESS AND DEVICE UTILIZING CIRCULATING AMMONIA WATER REFRIGERATION
Document Type and Number:
WIPO Patent Application WO/2021/128901
Kind Code:
A1
Abstract:
The present invention relates to a primary cooling process and device utilizing circulating ammonia water refrigeration, comprising a gas-liquid separator, a tar residue collecting device, a primary cooler, a lower condensate tank, a circulating ammonia water refrigeration unit, a tar residue pump, an emulsion spraying pump, a residual ammonia pump, a primary cooler condensate pump, a distilled ammonia removal unit pipeline, a tar delivery pipeline, a valve, a first-stage circulating ammonia tank, a second-stage circulating ammonia tank, a valve 1, a circulating ammonia pump, and a second-stage tar residue collecting device. The present invention has the following beneficial effects: by configuring the circulating ammonia water tanks in stages, an overly low temperature of circulating ammonia water entering the refrigeration unit can be avoided, while ensuring that the recycling temperature of the circulating ammonia water meets process requirements, thereby avoiding tar siltation in a gas collector, and so reducing the chance of blockage of a spray nozzle.
