Description

TECHNICAL FIELD

[0001] The utility model belongs to waste gas treatment technical field, specifically relates to a mobile ammonia gas absorption device. BACKGROUND

[0002] In the existing limited space scale of sulfur oil and gas reservoir fluid processing process, the generation of ammonia-containing waste gas becomes a problem to be solved. Sulfur oil and gas reservoir fluid in the experimental processing link, due to specific chemical reaction or physical change, will inevitably release ammonia-containing waste gas.

[0003] Under normal circumstances, limited space will choose to discharge these waste gases into the atmosphere through fume hood, ventilation hood or ventilating fan. However, this treatment method has many drawbacks. The untreated ammonia gas waste gas is directly discharged, which will first cause serious threat to the health of the limited space workers, and secondly, ammonia has a pungent smell, long-term contact may cause respiratory discomfort, eye irritation and other symptoms. Moreover, in the high concentration of ammonia environment, it may even cause poisoning and other serious consequences. These untreated ammonia gas waste gas discharged into the external environment will also cause pollution problems that cannot be ignored. Ammonia can react with other substances in the air, which may form secondary pollutants and have a negative impact on air quality. While the ammonia treatment device used in other industries has a certain effect on ammonia treatment, it has the problems of high price and large floor area. These devices are usually designed for large-scale industrial production, and their complex structure and large volume make them difficult to apply in limited space environment. On the one hand, the limited space has limited budget and cannot afford expensive ammonia treatment devices. On the other hand, the limited space is usually limited, and the device with large floor area will seriously occupy the experimental space, affecting the convenience and efficiency of experimental operation. In summary, the existing ammonia treatment method cannot meet the needs of limited space, and there is an urgent need for an ammonia treatment device specially designed for limited space, which can effectively treat ammonia waste gas and has the characteristics of reasonable price, small floor area and easy to move. CONTENT OF THE UTILITY MODEL

[0004] The utility model discloses a mobile ammonia gas absorption device to solve the problem of ammonia absorption and treatment difficulty in the limited space such as laboratory.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] A mobile ammonia gas absorption device includes a mobile trolley and an absorption tank. The mobile trolley includes a base plate, a push handle, and wheels. The wheels are fixed to the four corners of the bottom of the base plate by bolts. The push handle is installed on one side of the upper surface of the base plate and is fixedly connected to the base plate by a connecting mechanism. A mounting bracket that mates with the absorption tank is also welded to the surface of the base plate. The absorption tank is fixed to the mobile trolley by the mounting bracket. A liquid inlet is opened at the top of the absorption tank and a liquid outlet is opened at the bottom. An air pump is installed next to the liquid inlet and is connected to a gas distribution ring set inside the absorption tank by a pipeline.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. It solves the problem of difficult absorption and treatment of ammonia gas in confined spaces such as laboratories, preventing ammonia-containing gas from spreading and polluting the atmosphere; it protects the lives of personnel in confined spaces, improves the utilization rate of on-site space, and reduces the operation and maintenance costs of laboratories.

[0009] 2. The use of a mobile trolley and absorption tank makes the whole process convenient and improves the ammonia removal efficiency. The absorption tank is filled with absorbent liquid, which can chemically absorb the purged ammonia gas. The neutralized waste liquid is then discharged into the wastewater treatment pond, thus avoiding environmental pollution. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further explained below with reference to the accompanying drawings.

[0015] like Figures 1-3As shown, a mobile ammonia gas absorption device includes a mobile trolley 1 and an absorption tank 2. The mobile trolley 1 includes a base plate 101, a push handle 102, and wheels 103. The wheels 103 are fixed to the four corners of the bottom of the base plate 101 by bolts. The push handle 102 is installed on one side of the upper surface of the base plate 101 and is fixedly connected to the base plate 101 by a connecting mechanism. A mounting bracket that mates with the absorption tank 2 is also welded to the upper surface of the base plate 101. The absorption tank 2 is fixed to the mobile trolley 1 by the mounting bracket. The top of the absorption tank 2 has a liquid inlet 6 and the bottom has a liquid outlet 7. An air pump 3 is installed next to the liquid inlet 6 and is connected to a gas distribution ring 4 inside the absorption tank 2 by a pipe.

The outer gas distribution port 9 and the inner gas distribution port 8 are evenly arranged on the gas distribution ring in an alternating manner.

[0017] The inner gas outlet 8 is arranged inwards, causing the gas entering the inner gas outlet 8 to be ejected inwards in a concentrated manner; the outer gas outlet 9 is arranged outwards, causing the oxygen entering the outer gas outlet 9 to be ejected outwards in a radial manner; the opposing air currents formed by the inner gas outlet 8 and the outer gas outlet 9 are used to stir the liquid in the absorption tank, ensuring uniform gas-liquid mixing and improving the absorption effect.

[0018] Specifically, the absorption tank 2 can be a square tank or a cylindrical tank; in this embodiment, a square tank is used. To reduce overall weight, the absorption tank 2 can be made of plastic. Valves can be installed on the inlet and outlet of the absorption tank 2 to control the flow of absorbent liquid. The wheels 103 at the bottom of the trolley 1 can be wheels with foot brakes for easy fixing.

[0019] Specifically, the push handle 102 can be folded 90° relative to the base plate 101 via a connecting mechanism. The connecting mechanism can be a bolt and a connecting seat, or a pin and a connecting seat, to ensure that the push handle 102 can be folded relative to the base plate 101. When in use, the push handle 102 is opened; when not in use, the push handle 102 is laid down, saving space and making it convenient to use.
