Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, specifically to a combined structure of an ammonia-containing exhaust gas absorption tower for high-efficiency purification. Background Technology

[0002] Chemical reactions produce various wastes; solid, liquid, and gaseous wastes can all be generated. Among the gaseous wastes, common ones are toxic and harmful gases such as ammonia and hydrogen sulfide, which seriously pollute the environment.

[0003] Ammonia can also be used as an important chemical raw material. If it is recovered, it can save resources. Therefore, special equipment is needed to treat ammonia generated in industrial production or laboratory chemical research. Such equipment is called ammonia tail gas treatment equipment.

[0004] Conventional ammonia tail gas treatment towers suffer from irregular packing layers, resulting in insufficient contact between the ammonia tail gas and the absorbent liquid, leading to low absorption efficiency. Furthermore, the overall size and footprint of the treatment tower are relatively large. To address this issue, we propose a combined structure for a highly efficient ammonia tail gas absorption tower. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a combined structure of a highly efficient ammonia-containing tail gas absorption tower. The packing layer and the demister layer are optimized and combined. The packing layer adopts special structured packing with the characteristics of large specific surface area and high mass transfer efficiency, which can enable the ammonia-containing tail gas to fully contact the absorbent liquid and achieve efficient absorption, thus effectively solving the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined structure for a highly efficient ammonia-containing tail gas absorption tower, comprising an outer shell, with supporting legs fixedly connected in a circular array at the lower end of the outer shell, an air inlet channel in the middle of the lower surface of the outer shell, a honeycomb frame snapped into the middle of the inner part of the outer shell, and a packing frame snapped into the internal channel of the honeycomb frame, a connecting frame fixedly connected to the upper end of the inner part of the outer shell, a fixing groove in the upper surface of the connecting frame, and a demister snapped into the inside of the fixing groove, the middle part of the packing frame having a hexagonal structure, and a slot in the outer side of the packing frame, the demister being a folded plate type demister, and a limiting block fixedly connected to the outer ring side of the upper surface of the demister.

[0007] Furthermore, it also includes a reinforcing bracket, which is an arc-shaped connecting rod and is fixedly connected between the support legs. The reinforcing bracket can strengthen the structural strength between the support legs and prevent the support legs from deforming or bending, thus affecting the safety of the absorption tower during use.

[0008] Furthermore, it also includes a limiting ring, which is fixedly connected to the lower end of the inner surface of the outer shell, and the upper surface of the limiting ring is in contact with the lower surface of the honeycomb frame; the limiting ring can provide auxiliary support for the honeycomb frame and prevent the honeycomb frame from falling and affecting the normal use of the absorption tower.

[0009] Furthermore, it also includes a water collection trough, which is fixedly connected to the upper part of the inner surface of the outer shell, and the inner side of the water collection trough is inclined. The upper end of the water collection trough corresponds to the demister on the outer ring side. The water collection trough can collect the water condensed by the demister, preventing water from dripping onto the packing and affecting the absorption efficiency of the absorption tower, thus making the absorption tower more convenient to use.

[0010] Furthermore, it also includes a guide plate, which is fixedly connected to the inner bottom surface of the shell, and the upper end of the guide plate has an inward inclined structure; the guide plate can prevent the collected condensate and absorbent from flowing out of the absorption tower and affecting the surrounding environment, thereby making the use of the absorption tower safer.

[0011] Furthermore, it also includes a reflux plate, which is fixedly connected to the inner bottom surface of the outer shell by a connecting column, and the reflux plate covers the upper end of the guide plate; the reflux plate can effectively prevent dripping condensate from flowing out of the absorption tower.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This highly efficient ammonia-containing tail gas absorption tower combination structure has the following advantages:

[0013] 1. The packing layer and the demister layer have been optimized and combined. The packing layer uses special structured packing, which has the characteristics of large specific surface area and high mass transfer efficiency, enabling the ammonia-containing tail gas to fully contact the absorbent liquid and achieve efficient absorption.

[0014] 2. The demister layer uses high-performance demister materials to effectively remove mist droplets from the exhaust gas, reducing secondary pollution. The synergistic work of the packing layer and the demister layer significantly improves the purification efficiency of the absorption tower.

[0015] 3. The absorption tower has a reasonable tower structure design, which facilitates installation and maintenance. Attached Figure Description
