Description

1. Technical field

[0002] The utility model belongs to the technical field of hazardous waste disposal, and particularly relates to a desalting device at the bottom of a wet deacidification washing tower. (II) Background technology

[0004] Wet deacidification is to perform multi-stage spray washing of flue gas in a wet scrubber, so that SO2 and HCl in the flue gas are neutralized with alkaline circulating water, and a certain excess of alkaline solution is sprayed to ensure that the pH value of the circulating liquid is within a certain range to achieve the best deacidification effect. After the spray water is recycled, the acid gas is washed and neutralized to become salt dissolved in the water, which will tend to be saturated and the salt concentration in the spray water is getting higher and higher, requiring drainage and replacement, but a large amount of salt is still deposited at the bottom of the wet tower and cannot be discharged. After too much salt accumulation, the circulating pump filter is frequently blocked, and the wet tower circulation pipeline and spray gun are blocked, affecting the deacidification efficiency and the normal operation of the incinerator. At present, the full salt inside the wet deacidification tower is discharged from the bottom, but because the salt is deposited at the bottom of the tower and cannot be stirred, it is impossible to discharge all the salt deposited at the bottom in a static state. (III) Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, the utility model provides a desalting device at the bottom of a wet deacidification washing tower.

[0007] The utility model is realized through the following technical solutions:

[0008] A desalination device at the bottom of a wet deacidification washing tower comprises a tower body, and is characterized in that: a plurality of water inlet flange distributors are evenly arranged along the tangent direction at the bottom of the tower body, the water inlet flange distributors are respectively connected to water inlet pipes, a slope is arranged at the bottom of the tower body, and a sewage pipe connected to the tower body is arranged at the lowest point of the slope.

[0009] There are four water inlet flange distributors, which are respectively connected to 30︒, 120︒, 210︒, and 300︒ of the tower body.

[0010] The water inlet pipe is installed on the water inlet main pipe, and the water inlet main pipe is provided with a water inlet.

[0011] A spare port is installed on the water inlet main pipe.

[0012] The utility model has the beneficial effects of making the sediment and salt accumulation in the tower bottom circulate and rotate, and discharge them through the sewage pipe, thereby ensuring that the tower is discharged cleanly, greatly extending the normal production time of the incineration line, and keeping the deacidification efficiency in the best state.

[0020] The accompanying drawings are a specific embodiment of the utility model. This embodiment includes a tower body 1, and a plurality of water inlet flange distributors 2 are evenly arranged along the tangent direction at the bottom of the tower body 1. The water inlet flange distributors 2 are respectively connected to the water inlet pipes 3. A slope 4 is arranged at the bottom of the tower body 1, and a sewage pipe 5 connected to the tower body 1 is arranged at the lowest point of the slope 4. There are four water inlet flange distributors 2, and the four water inlet flange distributors 2 are respectively connected to 30︒, 120︒, 210︒, and 300︒ of the tower body 1. The water inlet pipe 3 is installed on the water inlet main pipe 6, and the water inlet main pipe 6 is provided with a water inlet port 7. The water inlet main pipe 6 is provided with a spare port 8.

[0021] The desalination device at the bottom of the wet deacidification washing tower of the utility model is adopted, and process water is introduced into the water inlet main pipe 6 through the water inlet 7, and the process water enters the water inlet flange distributor 2 through each water inlet pipe 3, and then is injected into the bottom of the tower body 1 at a high speed along the tangent direction of the inner wall of the tower body 1, so that the sediment and salt accumulation in the bottom of the tower are circulated and rotated, and discharged through the sewage pipe 5. The slope 4 is set in the tower to ensure that the discharge in the tower is cleaner and more thorough. By continuously jetting pressurized water to impact the salt accumulation at the bottom of the wet tower, the salt accumulation can be completely discharged from the tower through sewage discharge, and there will be no excessive accumulation of salt.
