Description

Anti-fouling elevated drain sumps

technical field

The utility model belongs to the field of converter gas wet dust removal, in particular to an elevated sewage tank for preventing fouling.

Background technique

The converter gas wet dedusting process is as follows: the temperature of the primary flue gas of the converter drops to about 900°C after passing through the vaporization cooling flue, and then enters the spray scrubber. After the flue gas passes through the spray scrubber, the large dust particles in the flue gas are basically eliminated. Attached to the water mist, under the action of gravity, the dirty washing water is integrated, settles at the lowest point at the bottom of the tower, flows to the elevated drainage tank through the pipeline and water sealer, and then flows to the dirty circulating water treatment station.

The long-term drainage of turbid water in the elevated drainage tank has accumulated over time, resulting in serious scale accumulation on the bottom and lower side walls of the tank, greatly reducing the water flow space in the tank, and it is necessary to manually clean up the scale in the tank in time, otherwise the normal drainage will be affected.

Utility model content

The purpose of the utility model is to provide an elevated drainage tank for anti-fouling, which can stir the muddy water in the tank, thereby preventing scaling in the tank, eliminating the need for workers to clean the dirt in the tank, and reducing the load.

The technical scheme adopted in the utility model is:

An elevated drainage tank for anti-fouling, the bottom of the elevated drainage tank is distributed with high-pressure air branch pipelines, the outlet of the high-pressure air branch pipeline is located inside the elevated drainage tank, and the inlet is connected to the high-pressure air main pipeline, the high-pressure air main pipeline and the compressed air source connect.

Further, a movable tank cover is provided above the elevated drainage tank.

Further, the distance between adjacent high-pressure air branch pipelines is 1m.

The beneficial effects of the utility model are:

1. Compressed air enters the elevated drainage tank through the high-pressure air main pipeline and high-pressure air branch pipeline, and stirs the turbid water in the tank, thereby preventing scaling in the tank, eliminating the need for workers to clean up the mud in the tank, and reducing the load and optimizing the design. Reduce investment.

2. The tank cover can prevent the turbid water from splashing out of the elevated drainage tank after the high-pressure air enters.

Fig. 1 is the schematic diagram of the utility model embodiment.

In the figure: 1-tank cover; 2-drainage tank; 3-turbid water; 4-compressed air branch pipeline; 5-compressed air main pipeline.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1, a kind of anti-fouling elevated sewage tank, the bottom of the elevated sewage tank 2 is distributed with a high-pressure air branch pipeline 4, and the outlet of the high-pressure air branch pipeline 4 is located inside the elevated sewage tank 2 (the high-pressure air branch pipeline 4 The outlet is either an airtight micropore or a one-way valve), the inlet is connected to the high-pressure air main pipeline 5, and the high-pressure air main pipeline 5 is connected to the compressed air source. The compressed air enters the elevated drainage tank 2 through the high-pressure air main pipeline 5 and the high-pressure air branch pipeline 4, and stirs the turbid water 3 in the tank, thereby preventing scaling in the tank, eliminating the need for workers to clean the mud in the tank, and reducing the load and optimizing Design, reduce investment.

As shown in FIG. 1 , in this embodiment, a movable tank cover 1 is provided above the elevated drainage tank 2 . The tank cover 1 can prevent the muddy water 3 from splashing out of the elevated drainage tank 2 after the high-pressure air enters.

In this embodiment, the distance between adjacent high-pressure air branch pipelines 4 is 1m.

It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should belong to the protection scope of the appended claims of the present utility model.
