Acid mist exhaust gas spray purification tower Maojing

Acid mist exhaust gas spray purification tower MaojingSuitable for the treatment of continuous and intermittent exhaust gas emissions, the acid mist exhaust gas spray purification tower has a low pressure drop. The acid mist exhaust gas spray purification tower consists of packing, spray device, defogging device, spray liquid circulation pump, and absorption tower.
(1) Packing material
The filling material is mainly used as a ventilation device, arranged at the lower part of the spray area of the acid mist exhaust gas spray purification tower. After passing through the tray, the flue gas is evenly distributed throughout the cross-section of the absorption tower. This air distribution device is necessary to improve absorption efficiency. In addition to evenly distributing the flue gas in the main spray area, the acid mist exhaust gas spray purification tower tray also allows the flue gas to fully contact the liquid film area of the absorption liquid or washing liquid on the tray. The tray structure is a porous plate with a partition cofferdam, which is divided into plates for easy access from the absorption tower manhole and horizontally placed on the tray support structure.
(2) Spray device
The internal spray system of the acid mist exhaust gas spray purification tower is a mesh system composed of a distribution main pipe and nozzles. The recirculation pump of the acid mist exhaust gas spray purification tower corresponds to a spray layer, and a hollow cone nozzle is installed on the spray layer to atomize the spray liquid. The spray liquid is transported by the acid mist exhaust gas spray purification tower recirculation pump to the nozzle and sprayed into the exhaust gas. The spray system can evenly distribute the slurry in the absorption tower, and the flow rate through each spray layer is equal.
(3) Mist removal device
Used for separating liquid droplets carried by flue gas. The acid mist exhaust gas spray purification tower demister is arranged on the upper part of a spray component behind the top of the absorption tower. After passing through the circulating slurry spray layer, the smoke continuously flows through the demister, and the droplets remain on the baffle due to inertia. Due to the presence of solid substances in the retained droplets, there is a risk of scaling on the baffle, and regular cleaning is necessary to remove any slurry droplets.
(4) Spray liquid circulation pump
The acid mist exhaust gas spray purification tower recirculation pump is installed next to the absorption tower for the recirculation of the spray liquid inside the absorption tower. Adopting single flow and single-stage horizontal centrifugal pumps, including pump casing, impeller, shaft, guide bearing, outlet elbow, bottom plate, inlet, sealing box, shaft seal, foundation frame, anchor bolts, mechanical seal, and all pipelines, valves, local instruments and motors.
(5) Acid mist exhaust gas spray purification tower
The body of the acid mist exhaust gas spray purification tower adopts a fiberglass structure.

Acid mist exhaust gas spray purification tower MaojingUsing alkaline or acidic solution as an absorbent, the absorbent is added to the circulating water tank of the acid mist exhaust gas spray purification tower, and then sprayed out through the high-pressure nozzle of the spray tower, so that the absorbent can reach an atomized state, thereby increasing the contact surface area between the absorbent and the acid reducing exhaust gas, and slowly flowing through the filled packing layer. Then, it comes into contact with the incoming acidic and alkaline exhaust gas to undergo neutralization reaction, so that the exhaust gas can be purified and discharged in compliance with standards.
