Description

High-efficient aqueous ammonia, alkali lye mixing arrangement

Technical Field

The utility model relates to a mixing apparatus, specifically speaking are high-efficient aqueous ammonia, alkali lye mixing arrangement belongs to the liquid mixing arrangement field.

Background

The alkali liquor pipeline of the ammonia still designed in the prior art is directly merged with the residual ammonia water in the daily operation, and the blockage in the residual ammonia water pipeline is serious. The blockage in the tower is serious because the alkali liquor in the residual ammonia water pipe is not uniformly mixed with the ammonia water; during the operation, the tower body has a pressure building condition, so the operation temperature cannot meet the process requirement, and meanwhile, a great potential safety hazard exists during the operation. Blockage maintenance of an ammonia still relates to special operations such as high-altitude operation and limited space, and the tower is filled with highly toxic and corrosive media such as ammonia gas, tar, liquid caustic soda and partial volatile organic compounds, so that the maintenance safety risk is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to design a high-efficiency ammonia water and alkali liquor mixing device, wherein the liquid alkali and the ammonia water are fully and uniformly mixed before entering an ammonia still, thereby effectively avoiding the blockage of a tower body and a pipeline caused by the nonuniform mixing of the liquid; reduce tower body, pipeline maintenance frequency, effectively reduce the safe risk during the maintenance simultaneously, alkali lye, aqueous ammonia misce bene are favorable to the ammonium salt of chemical combination state to be resolved, improve ammonia distillation efficiency greatly.

The technical scheme of the utility model is that:

a high-efficiency ammonia water and alkali liquor mixing device comprises an ammonia still, wherein the inlet end of the ammonia still is connected with a liquid mixer, the inlet end of the liquid mixer is respectively communicated with an alkali liquor conveying pipeline and a residual ammonia water conveying pipeline, a liquid mixer is additionally arranged on a pipeline of the original residual ammonia water into the ammonia still, the liquid alkali and the ammonia water are fully and uniformly mixed before entering the ammonia still, and the blockage of a tower body and a pipeline caused by the nonuniform liquid mixing is effectively avoided; the maintenance frequency of the tower body and the pipeline is reduced, and meanwhile, the safety risk in the maintenance period is effectively reduced; the alkali liquor and the ammonia water are uniformly mixed, so that the ammonium salt in a chemical compound state can be resolved, and the ammonia distillation efficiency is greatly improved.

The two ammonia stills are arranged, and the outlet ends of the liquid mixer are respectively communicated with the inlets of the two ammonia stills through pipelines.

The utility model has the advantages that:

(1) the ammonia distillation effect is obviously improved, the ammonia nitrogen in the wastewater is reduced, the biochemical treatment load is effectively reduced, the consumption of auxiliary materials is reduced, and the production cost is reduced;

(2) the content of ammonia volatilized from the desulfurization solution is increased, the PH of the desulfurization solution is ensured, and the desulfurization efficiency is improved.

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a schematic structural diagram of a high-efficiency ammonia water and alkali liquor mixing device according to an embodiment of the present invention.

Detailed Description

The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.

Example 1

As shown in fig. 1, a high-efficiency ammonia water and alkali liquor mixing device comprises an ammonia still 4, wherein the ammonia still comprises a No. 1 ammonia still and a No. 2 ammonia still, the inlet ends of the No. 1 ammonia still and the No. 2 ammonia still are connected with a liquid mixer 1, the inlet end of the liquid mixer 1 is respectively communicated with an alkali liquor conveying pipeline 2 and a residual ammonia water conveying pipeline 3, a liquid mixer is additionally arranged on a pipeline of the original residual ammonia water entering the ammonia still, the liquid alkali and the ammonia water are fully and uniformly mixed before entering the ammonia still, and the blockage of a tower body and a pipeline caused by the non-uniform liquid mixing is effectively avoided; the maintenance frequency of the tower body and the pipeline is reduced, and meanwhile, the safety risk in the maintenance period is effectively reduced; the alkali liquor and the ammonia water are uniformly mixed, so that the ammonium salt in a chemical compound state can be resolved, and the ammonia distillation efficiency is greatly improved.

The liquid mixer is internally provided with a W-shaped baffle plate which is arranged perpendicular to the horizontal plane, the distance between the plates is 100mm, alkali liquor vertically enters the mixer along the horizontal direction, and the alkali liquor enters the mixer to be rapidly mixed with ammonia water because the conveying pressure of the alkali liquor is greater than that of the ammonia water.
