Description

Technical Field

[0001] This utility model relates to the field of scrubbing tower technology, specifically to a high-efficiency gas scrubbing tower. Background Technology

[0002] In coal gasification technology, raw coal and oxygen react to produce syngas through a gasification reaction. Syngas contains a large amount of dust particles, which need to be gradually removed by washing equipment. Then, the syngas with lower dust content is transported to the next stage for processing and application. If the syngas washing and dust removal effect is poor, a large amount of ash particles will enter the washing tower with the syngas. If a hooded tray is used, the high-temperature ash water from the washing and the condensation of the syngas will generate a large amount of dust, which makes the hooded tray prone to blockage or jamming, resulting in serious water carryover in the syngas and affecting the stable operation of the system.

[0003] Therefore, improvements should be made to address the aforementioned issues. Utility Model Content

[0004] This invention proposes a high-efficiency gas scrubbing tower, which solves the problem in related technologies where, if a hooded tray is used, the high-temperature ash water from the scrubbing process condenses with the syngas, generating a large amount of dust, which easily causes the hooded tray to become clogged or jammed, resulting in severe water carryover in the syngas and affecting the stable operation of the system.

[0039] In this embodiment, to achieve a recyclable washing and dispersing effect, a washing and dispersing component 6 is designed. An inner shell 6-1 is fixed inside the main tower body 1, and a circulation pump 5 is installed in the inner shell 6-1. A central pipe 6-2 connected to the output end of the circulation pump 5 is provided on the top of the inner shell 6-1. A dispersing cover 6-3 is provided on the upper end of the central pipe 6-2 for concentrated upward spraying. A top cover 6-4 is provided on the top of the main tower body 1, and a protrusion 6-5 is provided on the surface to disperse the sprayed washing water and make it fall, improving the coverage effect. A rotating sleeve is provided on the central pipe 6-2. A rotating sleeve 6-6 is connected to the main tower body 1. Multiple trays 6-7 and baffles 6-8 are fixed to the outside of the rotating sleeve 6-6 to disperse the washing water and promote the effect. Multiple extension rods 6-9 are also fixed to the main tower body 1. External gears 6-10 are provided at the outer ends of the extension rods 6-9. An outer cover 6-11 is provided on the outer wall of the main tower body 1. A drive motor 6-12 is provided at the bottom of the outer cover 6-11 and a drive gear 6-13 is provided at the output end. The drive gear 6-13 meshes with the external gear 6-10 and the rotation of the trays 6-7 can be controlled by the drive motor 6-12.

[0040] Furthermore, the filter assembly 7 includes an isolation cylinder 7-1, which is fixed to the bottom of the air intake sub-tower 2. An adsorption layer 7-2 is provided at the bottom of the air intake sub-tower 2 and is attached to the outer wall of the isolation cylinder 7-1. An extension pipe 7-3 is provided at the water inlet end of the circulation pump 5. A sleeve 7-4 is provided on the surface of the extension pipe 7-3.

A filter hole 7-6 is opened on the bottom surface of the central cover 7-5.

[0041] In this embodiment, a filter assembly 7 is designed to achieve the effect of filtering washing ash water. An isolation cylinder 7-1 is set at the bottom inside the air inlet sub-tower 2, and an adsorption layer 7-2 is filled on the outside to adsorb washing ash water. An extension pipe 7-3 and a sleeve 7-4 are set at the water inlet end of the circulation pump 5. A central cover 7-5 is fitted at the lower end of the extension pipe 7-3 and has filter holes 7-6 at the bottom to filter the washing water pumped by the circulation pump 5 and avoid clogging. The central cover 7-5 is inserted into the sleeve 7-4 and can be separated and pulled out.

[0042] Furthermore, the top cover 6-4 has an arc-shaped transition structure in cross-section, and the convex layer 6-5 has a spiral structure.

[0045] In this embodiment, by bending the bottom inward, the washing water can be concentrated and flow into the tray 6-7 of the next layer.

[0046] Furthermore, the dispersion hood 6-3 has an overall spherical structure.

[0047] In this embodiment, the spherical structure combined with the opening allows the washing water to be sprayed fully onto the top cover 6-4, improving the diffusion washing effect.

[0048] When coal gas needs to be processed, the mixed gas enters at the inlet 4 and flows upward. Washing water is stored in the main tower body 1 in advance. The circulating pump 5 draws the washing water and sprays it through the dispersion hood 6-3 to the top hood 6-4. After diffusion, it falls down, covering the coal gas and absorbing ash. It then falls down and absorbs coal ash through the adsorption layer 7-2. After being filtered through the filter holes 7-6, it is continuously circulated by suction. The washing water falls on the surface of the tower tray 6-7 and the drive motor 6-12 is started. The drive gear 6-13 and the external gear 6-10 work together to control the rotation of multiple tower trays 6-7, keeping them in a rotating state, reducing ash accumulation, and discharging waste at the bottom. The intake auxiliary tower body 2 can be disassembled to replace the adsorption layer 7-2 and clean the filter holes 7-6 on the bottom surface of the concentration hood 7-5.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
