Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste gas desulfurization cylinders, in particular to an industrial waste gas desulfurization cylinder. Background Art

[0002] As we all know, industrial waste gas refers to the general term for various pollutant gases discharged into the air during the combustion of fuel and production processes in the factory area of ​​an enterprise. Industrial waste gas may contain carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead and mercury, beryllium, smoke and productive dust. Industrial waste gas is discharged into the atmosphere and will pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have an accumulation effect, which will more seriously endanger human health. Therefore, when industrial waste gas is discharged, using a desulfurization cylinder to desulfurize the industrial waste gas is an important treatment process.

[0003] When the existing desulfurization cylinder is in use, after the industrial waste gas enters the desulfurization cylinder, the alkaline solution sprayed out by atomization is neutralized with the industrial waste gas to achieve desulfurization. Usually, the air inlet pipe is installed in the middle of the desulfurization cylinder and is directly discharged into the desulfurization cylinder. Since the waste gas stays in the desulfurization cylinder for too short a time, the neutralization reaction between the alkaline solution and the sulfide in the waste gas is not complete, resulting in poor desulfurization effect on the industrial waste gas. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides an industrial waste gas desulfurization cylinder, which solves the problem that the waste gas stays in the desulfurization cylinder too short, resulting in incomplete neutralization reaction between the alkaline solution and the sulfide in the waste gas, and thus poor desulfurization effect on the industrial waste gas.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an industrial waste gas desulfurization cylinder, comprising a desulfurization cylinder body, the top of the desulfurization cylinder body is connected to an air outlet pipe, the bottom of the desulfurization cylinder body is installed with a plurality of support rods, the bottom of the desulfurization cylinder body is connected to a liquid inlet pipe, a valve is installed on the liquid inlet pipe, an air inlet pipe is installed in the middle of the desulfurization cylinder body, an elbow is provided at one end of the air inlet pipe, and a fixed pipe is connected to the bottom of the elbow, a rotating pipe is installed on the fixed pipe, an air outlet wheel is connected to the bottom of the rotating pipe, a plurality of baffles are provided on the air outlet wheel, a delivery pipe is installed between the middle and the bottom of the desulfurization cylinder body, a spray device is installed at one end of the delivery pipe, a delivery pump is installed on the delivery pipe, and a spiral belt is provided inside the desulfurization cylinder body.

[0008] Furthermore, a rotation groove is provided on the fixed tube, and the rotation groove is connected to the rotating tube through rotation.

[0009] Furthermore, both sides of each baffle are arc-shaped surfaces, and a certain distance is set between two adjacent baffles.

[0010] Furthermore, the liquid inlet pipe is connected to a liquid supply device.

[0011] Furthermore, the delivery pump is electrically connected to an external power source.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides an industrial waste gas desulfurization cylinder, which has the following beneficial effects:

[0014] The industrial waste gas desulfurization cylinder is achieved by installing a fixed pipe at one end of the inlet pipe, and the fixed pipe is connected to the rotating pipe by rotation, and a plurality of baffles are arranged on the air outlet wheel, and both sides of each baffle are arc-shaped surfaces. When the waste gas passes through the air outlet wheel, the baffles can be pushed to rotate the air outlet wheel and make the waste gas rotate inside the desulfurization cylinder. When the waste gas reaches the spiral belt, it rotates upward, which increases the residence time of the waste gas in the desulfurization cylinder, allows the alkaline solution to be fully mixed with the waste gas, and improves the desulfurization effect.
