Description

Technical Field

[0001] This utility model belongs to the field of washing tower technology, specifically relating to a methanol washing tower for environmental engineering. Background Technology

[0002] A gas scrubbing tower is a new type of gas purification equipment. It is an improvement upon the floating packing layer gas purifier and is widely used in pretreatment for industrial waste gas purification and dust removal, achieving excellent purification results. For coal gasification processes, gas scrubbing is unavoidable; this unit operation is used regardless of the coal gasification technology. Because its working principle is similar to a washing process, it is named a gas scrubbing tower.

[0003] Existing methanol scrubbing towers used in environmental protection projects still have some shortcomings. Most of them are not thorough enough in removing methanol, which leads to safety hazards when gas is emitted. Moreover, cleaning the scrubbing tower is quite troublesome. Therefore, we propose a methanol scrubbing tower for environmental protection projects. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: a methanol scrubbing tower for environmental protection engineering, including a scrubbing tower body 1 and an air inlet pipe 2. The air inlet pipe 2 is provided on one side of the bottom of the scrubbing tower body 1. A gas distributor 3 is provided inside the scrubbing tower body 1. The gas distributor 3 is fixedly connected to the scrubbing tower body 1. A first packing layer 4 is provided inside the scrubbing tower body 1. A first branch pipe 5 is also provided inside the scrubbing tower body 1. A first spray 6 is provided on one side of the first branch pipe 5. Multiple first sprays 6 are provided. A second packing layer 7 is provided in the middle of the scrubbing tower body 1. A second branch pipe 8 is provided inside the scrubbing tower body 1.

A third spray 11 is provided on one side of the flushing pipe 10.

[0020] In this embodiment, when using the methanol scrubbing tower for environmental engineering, coal gas enters through the inlet pipe 2. The gas distributor 3 disperses the coal gas, allowing it to diffuse evenly upwards, thus making the scrubbing more thorough. The first packing layer 4 and the second packing layer 7 absorb harmful substances in the coal gas. The first spray 6 and the second spray 9 wash the coal gas, removing methanol. Due to the even diffusion of the coal gas, after absorption by the two packing layers and washing by the two sprays, the methanol is removed more thoroughly. The flushing pipe 10 and the third spray 11 facilitate the cleaning of the scrubbing tower.

[0021] Specifically, a liquid distributor 12 is provided on the top inner side of the washing tower body 1. The liquid distributor 12 is detachably connected to the washing tower body 1. A water tank 13 is provided on one side of the washing tower body 1. The water tank 13 contains washing liquid. A water pipe 14 is provided on one side of the water tank 13. A water pump 15 is provided at one end of the water pipe 14. The water pump 15 and the water tank 13 are fixed by screws. A funnel 16 is provided on the bottom inner side of the washing tower body 1. A drain pipe 17 is provided at the bottom of the funnel 16. The drain pipe 17 extends to the outside of the washing tower body 1. A third packing layer 18 is provided inside the washing tower body 1. The third packing layer 18 is fixedly connected to the washing tower body 1. An air outlet pipe 19 is provided on the top of the washing tower body 1. The air outlet pipe 19 is interconnected with the washing tower body 1.

[0022] In this embodiment, the cleaning liquid enters from the rinsing pipe 10 and is then sprayed out by the third spray 11 during the cleaning of the washing tower via the liquid distributor 12. The liquid distributor 12 can distribute the cleaning liquid so that it falls into the interior of the washing tower for a more thorough cleaning. The washing function of the device is realized through the water tank 13, water pipe 14 and water pump 15. The water pump 15 is started to draw out the washing liquid inside the water tank 13, which is transported into the interior of the branch pipe by the water pipe 14 and then sprayed out by the spray to achieve the purpose of washing. The treated gas is discharged through the air outlet pipe 19.
