Description

Net disk cutting bubble film absorbing and dust removing equipment

Technical Field

The utility model relates to a dust collecting equipment technical field, concretely relates to net dish cutting bubble membrane absorbs, dust collecting equipment.

Background

With the increasing atmospheric pollution and the increasingly severe environmental protection forms, countries and various provinces and cities have successively stricter exhaust emission standards, and the pollutant content in the exhaust gas is gradually reduced, so that more efficient pollution treatment equipment is needed. Among them, absorption of soluble but volatile components and deep fine dust removal are relatively difficult fields.

When components soluble in water or solvent are absorbed by a conventional spray tower and a packed tower, the conditions of back mixing and secondary steam stripping are easy to exist, so that the exhaust concentration cannot be reduced, the emission standard requirement cannot be met, and only other technical equipment can be matched, so that the process chain is long. The problem of exhaust and liquid carrying also exists in deep fine dust removal, the exhaust index is high due to salt and particles in liquid drops, the deep fine dust removal device can only be matched with complex dust removal equipment such as wet electricity, and the operation cost is high.

In the technical scheme, the device is in a tower-type structure (square or round), a plurality of layers of net disks are arranged in the device, absorption liquid is stored in the tower, and tail gas is fed in and discharged out through a pump with smaller power and overflow circulation.

The air flow enters the equipment through the guide elbow, impacts the guide cone downwards and then forms a gas-liquid mixed fluid with the absorption liquid and changes direction upwards.

3-5 layers of net discs are arranged above the diversion cone, gas-liquid mixed fluid upwards passes through the net discs step by step at a high gas speed, the gas is cut and extruded for many times in the process, the gas is cut into smaller units, the contact area of the gas and the liquid is increased, and the extrusion and impact effects accelerate the mixing of the gas and the liquid.

Each layer of net plate is provided with an independent circulating cavity, one part of circulating liquid which absorbs and traps pollutants is drained from the circulating cavity to the overflow port, and the other part of circulating liquid passes through the upper layer of net plate along with air flow.

The top of the tower is provided with a simple dewatering structure to ensure that the exhaust does not carry liquid.

The washing nozzle is arranged above the net disk, and the net disk is washed on line to prevent the structure from blocking the net holes.

The overflow adopts adjustable mechanical structure, and the liquid level height in the adjustable tower of control through the overflow position obtains different purifying effect.

The net disks are made of thin metal or nonmetal strips, holes are triangular or square, the hole diameters of all layers of net disks are different and are gradually reduced from bottom to top, the net penetrating gas speed is increased, and gas-liquid mixing is enhanced.

The utility model provides a net dish cutting bubble membrane absorbs, dust collecting equipment. According to the technical scheme, a larger gas-liquid contact interface is obtained through the principles of impact, cutting and extrusion, a large-area moving bubble film is formed between gas and liquid fluid, and a larger driving force is provided for components in gas to enter a liquid phase. Soluble components can easily enter the absorption liquid, particles are more easily wetted and captured by a water film, the whole tower efficiency is high, and the purification efficiency can reach more than 90%. Because a spraying structure is not adopted, the gas and liquid are less carried, and the effect of exhausting without carrying liquid can be achieved by simple demisting. Has excellent purifying effect on soluble components and fine particles. The utility model discloses can be used to water purifying agent types soluble particulate matter such as polyaluminium chloride, calcium chloride and purify, VOCs component solvent absorbs, and volatile inorganic substance is like hydrogen chloride, hydrogen fluoride absorb, contains the ultralow emission of particulate matter flue gas etc..
