Claims

The invention relates to a technique for purifying technological, ventilating gas containing fine dust and can be used for wet gas cleaning in the metallurgical, chemical, mining and other industries. It is known to a gas purifier consisting of a confuser, a neck, a diffuor, a rosette. devices and a drop of saddle camera. A disadvantage of the known device is the relatively low efficiency of gas cleaning from fine dust and relatively large dimensions of the device. A device for gas purification comprising a successively installed confuser, throat and diffuser, irrigator 2, is known. A disadvantage of the known device is the relatively low efficiency of gas cleaning from fine Dust and relatively large capital and operating costs. The purpose of the invention is to increase the gas purification efficiency, reduce capital and operating costs and reduce the size of the installation. The goal is achieved due to the fact that in the proposed device the neck is made in the form of a spiral turn 1215 neck diameters and a radius of curvature equal to 1.5-2.5 neck diameters, the device is equipped with a helix-shaped collector on the outside. It is advisable to place the sludge collector on the neck section in the same horizontal plane with its axis, and on the diffuser section install it obliquely and provide its bottom end with a hydraulic lock. Fig, 1 is given the proposed device, top view; in fig. 2 — node 1 of FIG. Ij in FIG. 3 shows section A-A in FIG. Ij in FIG. 4 is a view B in FIG. 1. A device for gas cleaning includes a collector of 1 gaseous gas, inside of which in the upper part there is a perforated tube 2 for supplying liquid with groups of slit-like holes 3 over each mm. The collector 1 is connected through a confuser 4 with a spiral-shaped neck 5, which terminates with the diffuser 6. A slit-shaped slime collector 7 is located on the outer side along the entire length of the neck 5 and the diffuser 6. are in the same horizontal plane, and in the section of the diffuser 6 the sludge collector smoothly goes down and ends with a hydraulic lock 8. Inside the neck 5 there is a perforated pipe 9 on the inner side of the spiral with slit-like openings cut 100-150 mm. The perforated pipe goes along the length of the neck section, which is enclosed within 180 of the angle of the solution of the spiral of the neck 5. At the end of the collector 1 of gas, there is also a sludge line with a hydraulic lock 1O, which is located below the collector. The device works as follows. Dust-laden gas in a sloping co1 gas polluter is intensively irrigated with water. Frequently, the dust, wetted with water, is precipitated and carried with a stream of water into the sludge line with a water trap. Y. To achieve these goals, the gas velocity is maintained within 4-6 m / s. The length of the wet section of the gas collector depends on the initial dust content and the gas temperature. The gas in it is about 70g-8O% and is cooled. After the collector of the dirty gas, the gas enters the confuser 4 and further into the spiral neck. 0 throat 5, the gas is intensively irrigated with water from a perforated pipe 9 and acquires a high speed of movement (60-80 m / s), as a result of which the dust is coagulated efficiently, and under the action of centrifugal forces, not 5, coarse particles enlarged are thrown against the walls, captured by a film of water and removed through a slit-like sludge collector 7 and a hydraulic lock 8. At the throat 5, simultaneously with the cleaning of dust, the gas is cooled and separate gas components are absorbed In water or in other irrigation liquids. The final removal of sludge and dropping liquid from the gas stream takes place in the non-wetted part of the neck 5. The gas, cleared of dust and water droplets, passed through the diffuser 6, enters the clean gas collector. Dust collection efficiency is 98-99%. Claims 1. Gas purification device comprising successively installed confuser, throat and diffuser, sprinkler, characterized in that, in order to increase the cleaning efficiency of hectares, reduce capital and operating costs, the throat is made in the form of a 12-15 coil the diameters of the neck and the radius of curvature equal to 1.5-2.5 diameters of the mountains “halves”, the device is equipped with the installed c. the outer side of the slit-like sludge bore 2. The device according to claim 1, characterized in that the sludge collector at the neck section is located in the same horizontal plane with its axis, and at the diffuser section it is installed obliquely and its lower end is provided with a hydraulic lock.
