Description

Technical Field

[0001] The utility model relates to the field of acid production from desulfurization waste liquid, in particular to a purge stirring slurry storage tank. Background Art

[0002] Since the operation of the desulfurization waste liquid acid production, the process gas cooler has been unstable. The main reason is that the waste liquid spray gun head is not well atomized, causing the resistance of the process gas cooler to rise, and the production is forced to stop. The suspension of production caused the internal liquid level of the slurry storage tank to be too high and the slurry to be stratified. The original design only relied on the agitator originally designed for the slurry storage tank to stir the internal slurry. After calibration, it was found that after the liquid level of the storage tank exceeded 4m, the agitator lost its original function due to the high liquid level. When the slurry enters the incinerator for combustion, a large amount of olefinic acid is produced, and the concentrated acid output is small, which affects the product yield. If production operation is to be guaranteed, the problem of slurry stratification in the storage tank can only be solved by cleaning the tank. The manpower and material costs involved in cleaning the tank are too high, and there are certain safety risks in cleaning the tank. During the cleaning period, the acid production is in a state of suspension, and the desulfurization sulfur melting system needs to be opened, which increases the processing cost, which is very unfavorable to the stable operation of the acid production and the salt reduction of the desulfurization liquid in the gas purification operation area. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a purging and stirring slurry storage tank to ensure that the materials in the slurry storage tank are continuous, stable and not stratified.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A purged and stirred slurry storage tank, wherein the bottom of the side of the slurry storage tank is respectively connected to a slurry inlet and a slurry outlet, the slurry storage tank is connected to a nitrogen main pipe, and a first nozzle, a second nozzle, a third nozzle and a fourth nozzle are arranged on the bottom surface of the slurry storage tank, the first nozzle, the second nozzle, the third nozzle and the fourth nozzle are all arranged in a circuitous manner, one end is an air inlet end, and the other end is a closed end, the nitrogen main pipe is respectively connected to the first nozzle, the second nozzle, the third nozzle and the fourth nozzle through a nitrogen branch pipe 1, a nitrogen branch pipe 2, a nitrogen branch pipe 3 and a nitrogen branch pipe 4, and the first nozzle, the second nozzle, the third nozzle and the fourth nozzle are all connected to a plurality of nozzles.

[0006] The first nozzle, the second nozzle, the third nozzle and the fourth nozzle are evenly distributed on the circumference of the bottom surface of the slurry storage tank.

[0007] The outlet end of the nozzle is a flat port.

[0008] The nozzle forms an angle of 40°-50° with the pipe bodies of the first nozzle, the second nozzle, the third nozzle and the fourth nozzle.

[0009] The nitrogen main pipe is connected to an external gas source.

[0010] The gas pressures in the nitrogen branch pipe 1, nitrogen branch pipe 2, nitrogen branch pipe 3 and nitrogen branch pipe 4 are all 0.4 MPa to 0.5 MPa.

[0011] Compared with the existing technology, the beneficial effects of the utility model are:

[0012] The utility model ensures that the materials in the slurry storage tank are continuous, stable and non-stratified, greatly reduces the task of tank cleaning, completely solves the huge processing cost caused by the stratification of slurry inside the storage tank, eliminates the adverse effects of frequent shutdown of acid production causing the increase of secondary salt and unqualified desulfurization indicators, and ensures the stable operation of desulfurization waste liquid acid production. The stirring method of the traditional agitator is changed, avoiding the shutdown of the agitator due to failure and reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
