Device for recycling organic entrained spent acid extracted through wet process and recycling method by using recycling device

Abstract

The invention relates to a device for recycling organic entrained spent acid extracted through a wet process and a recycling method by using the device. A clarifying chamber, a mixing chamber, a blank organic transfer barrel and a main body tank which are at the last level are communicated with each other through siphons. Spent acid in the blank organic transfer barrel and the mixing chamber is guided into the clarifying chamber through the siphons and enters into the main body tank through a water-phase overflowing port of the clarifying chamber, and the height of liquid level at every position is the same. A water-phase overflowing port of the main body tank at the last level is connected with a spiral lead screw, and the height of the water-phase overflowing port of the main body tank can be adjusted by rotating the spiral lead screw so as to control the height of the spent acid allowed to be reserved at every position. A regeneration total valve is connected with a tap water inletpipe and is closed after the tap water inlet pipe is opened to enable water to be filled in all the siphons, and then three regeneration branch valves are opened so that siphon can be activated and started. By means of the device for recycling the organic entrained spent acid extracted through the wet process and the recycling method by using the device, the entrained spent acid can be recycled immediately, cleanly, safely, stably and timely in an unpowered mode, acid ammonia consumption in a wet smelting process is reduced, product quality is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the recovery and utilization of a wet extraction separation smelting process, in particular to a wet extraction organic entrainment residual acid recovery device and a recovery method thereof. Background technique [0002] In wet smelting, due to environmental conditions, process conditions, flow ratio, clarification time during stripping, and insufficient tank capacity, etc., the final blank organics are seriously entrained with stripped residual acid, and these residual acids are not easy to be recycled uniformly. Direct discharge is wasteful. If it is not properly handled, it will lead to increased acid ammonia consumption and affect product quality. It has always been an intractable problem in the production of extraction process. Some technicians solve this problem by infinitely expanding the ratio of the clarification chamber to the mixing chamber of the tank body, but this will lead to an increase in the initial investm...

Problems solved by technology

[0002] In wet smelting, due to environmental conditions, process conditions, flow ratio, clarification time during stripping, and insufficient tank capacity, etc., the final blank organics are seriously entrained with stripped residual acid, and these residual acids are not easy to be recycled uniformly. Direct discharge and waste, if not handled properly, it will lead to increased acid ammonia consumption and affect product quality

It has always been an intractable problem in the production of extraction process

Some technicians solve this problem by infinitely expanding the ratio of the clarification chamber to the mixing chamber of the tank body, but this will lead to an increase in the initial investment cost, and there are disadvantages such as excessively large valuable raw materials in the tank volume.
