Problems solved by technology
Because there is no stirring device, the gypsum mixed water will accumulate more and more at the bottom of the gas-liquid separator, eventually resulting in the impeller of the flushing water pump being often blocked by gypsum, and the flushing water nozzle is often blocked, which increases the maintenance workers and operators. The amount of labor has greatly reduced the driving rate of phosphoric acid (clearing the pan water at least twice per shift) and the washing rate of gypsum. The gypsum of the gas-liquid separator is finally discharged to the sewage tank of phosphoric acid, up to 2-3 clean up every day

Embodiment Construction
[0013] Such as figure 1 As shown, the improved method for recycling gypsum applied to the flushing water cloth includes the following improvements: a flushing water tank is added to the east side of the original wet funnel, and a flushing water pump is installed on one side of the flushing water tank, in which the cloth water enters The flush pan water tank, the hot water pump replenishes hot water to the flush pan water tank. The flush pan water tank is connected with a steam pipe to ensure the temperature of the gypsum water. An overflow is opened below the surface of the flush pan water tank. There is a sewage valve at the bottom of the flush pan, which can drain the gypsum water in the flush pan during long-term parking. The flush pan is equipped with high and low alarms;
[0014] The punching tank is 2000×2000mm in diameter and 7m in volume 3 , And with a stirring paddle;
[0015] The parameter of the flushing water pump is Q=50-60m 3 / h, P=75KW;
[0016] The water flow rate o...

The invention discloses an improved circulating utilization method applied to gypsum by distributed water of flushing disk water. The improved circulating utilization method is characterized in that a flushing disk water pump is arranged on one side of a flushing disk water tank, wherein the distributed water enters the flushing disk water tank, a hot water pump is used for supplementing hot water into the flushing disk water, a steam pipe is connected in the flushing disk water tank, an overflow port is formed the surface of the flushing disk water tank, a blowdown valve is arranged at the bottom of the flushing disk water tank, and a high-level alarm device and a low-level alarm device are arranged in the flushing disk water tank. The improved circulating utilization method has the following advantages: (1) the blockage situation of an impeller of the flushing disk water pump, which is caused by original gypsum water precipitation is overcome, and the maintenance labor capacity is greatly alleviated; (2) the quality of the flushing disk water is obviously improved, the blockage phenomenon of a flushing disk water spray nozzle is obviously reduced, the driving rate and the washing rate of phosphoric acid are greatly increased, and the overall labor intensity of workers is obviously alleviated; (3) the distributed water of the flushing disk water can be recycled in the flushing disk water tank, the gypsum is digested during the production, and a field environment is greatly improved.
Description
Technical field [0001] The invention relates to an improved process for a gypsum water recycling system, in particular to a method for improving the recycling use of gypsum water applied to a flushing water cloth. Background technique [0002] Before the improvement of the method, the flushing water cloth designed by Sichuan University was used to enter the gas-liquid separator and the fluorine absorption water was mixed together as filtered flushing water. Because there is no stirring device, the gypsum mixed water deposits more and more at the bottom of the gas-liquid separator, and eventually the impeller of the flushing pump is often blocked by gypsum, and the flushing nozzle is often blocked, which increases the maintenance and operation The amount of labor has greatly reduced the phosphoric acid drive rate (at least two flushes per shift) and the washing rate of gypsum. The gypsum of the gas-liquid separator is finally discharged to the phosphoric acid sewage tank, up to 2-...
