Adsorption flow adjusting and pressure relieving device of adsorption tower

Technical Field

The utility model belongs to the technical field of the gold refines equipment, concretely relates to adsorption tower adsorbs flow control and pressure relief device.

Background

In the heap leaching gold extraction process, gold-containing precious liquid obtained by spraying and leaching ores flows back to a workshop precious liquid pool through a pipeline, and is pumped into an adsorption tower filled with activated carbon by a pump for adsorption, so that a gold-loaded carbon product is finally obtained. The water inlet pipe port of the adsorption tower used at present is arranged in the tower, water flows into the tower from the lower part through the water inlet pipe in the tower, and flows out from the upper part of the tower after being adsorbed by active carbon, and the adsorption process flow is shown in figure 1. (1) The centrifugal pump pumps water according to rated power to carry out adsorption operation, and the flow absorbed by the tower cannot be flexibly adjusted according to actual conditions. When the water flow is too large, the adsorption tower can be damaged, and water leakage of the tower is caused; when the water flow is too small, the activated carbon can be hardened, and the adsorption efficiency of the activated carbon is influenced. (2) When the pump is stopped, carbon in the adsorption tower can enter into the water inlet pipe under the action of the pressure of the return water, so that the water inlet pipe is blocked, and if the pump is restarted, the pump, the motor and the adsorption tower can be damaged under high pressure (mainly shown in that the edge of the upper part of the tower body is broken by washing, so that water leakage is caused). (3) When the water inlet or the water outlet of the adsorption tower is adjusted, the water inlet pipe of the adsorption tower is blocked by carbon. (4) 500-800 kg of carbon is filled in each adsorption tower, when the adsorption tower is blocked, the carbon in the adsorption tower needs to be discharged, and the adsorption operation can be continued after the carbon in the water inlet pipe is removed, so that the labor intensity is greatly increased. (5) The inlet tube is installed inside the tower, and is very inconvenient when clearing up, installing, changing it, need to enter the tower interior operation, and the noble liquid aquatic all contains the sodium cyanide of certain concentration, has the potential safety hazard in the operation process. (6) If the adsorption tower blocks carbon in rainy season, great difficulty is brought to flood control work.
