Description

 The invention relates to devices for cleaning gases from solid impurities and can be used in chemical, oil and other industries.

 A device for treating gases is known, comprising a housing with gas inlet pipes, an exhaust pipe, a separator, a curler made of flat blades made in the form of a rectangular trapezoid, which are inserted by the upper base into the exhaust pipe along its height and are attached with an inclined side to the inner surface of the latter, the blades being twisters are made with a slit located on the diagonal of the trapezoid [USSR Copyright Certificate 1526773, MKI B 01 D 47/02, 1989. Bull. 45].

 The disadvantage of this device is that with this arrangement of the blades in the exhaust pipe, its throughput is reduced, as well as in the complexity of the technological manufacture of the twist.

 The closest in technical essence and the achieved effect is a device for wet gas purification, comprising a housing with an inlet pipe, nozzles, a grill in the form of pair plates located symmetrically with respect to the axis of the inlet pipe, a fairing located along the axis of the inlet pipe, attached to the central pair of plates, moreover, each plate of the lattice is made of two rectangular parts, while the input parts of the plates are placed in parallel with the offset along the flow from the center with respect to each other and fixed rigidly to the walls of the inlet pipe, and the end parts are rotatable to the axis of the pipe [USSR Author's Certificate 1613143 MKI B 01 D 47/06, 1990. Bull. 46. (prototype)].

 The disadvantages of the known device are the high hydraulic resistance of the device, due to the installation of the lattice in the inlet of the apparatus and the complexity of the technological manufacture and installation of the plates of the lattice.

 The invention is aimed at solving the problem of improving the efficiency of purification of exhaust gases and environmental protection.

 This problem is solved due to the fact that the bubbler-vortex apparatus for wet gas purification in combination with a cyclone contains a cylindrical chamber with an inlet pipe, a curler, nozzles, connecting flanges with a cyclone and a sludge flow pipe into the sludge collector, while a curler is coaxially installed in the cylindrical chamber gas flow, which is a pair of intersecting planes, forming four blades, having a rectangular surface in the input section of the surface, gradually turning into a parabolic, pr why the blades form flow sections and are bent so that the greater part touch the inner surface of the body along their entire length and are rigidly attached to it, in addition, a central nozzle is installed in front of the curler, and peripheral nozzles are located in each flow section after the curler, and the cylindrical chamber itself connected with a slope to the cyclone taking into account the flow of sludge.

 The technical result provided by the bubbler-vortex apparatus is expressed in an increase in the efficiency of dust collection due to the installation of a gas flow swirl in the apparatus, central and peripheral nozzles, and also because the cylindrical chamber is inclined to the cyclone with allowance for sludge runoff, and a decrease in hydraulic the resistance of the device due to the choice of the optimal geometry of the rotor blades forming the flow sections, saving material resources and the area of industrial premises per Thu possibility of installing a bubble-vortex apparatus in dust collection ducts system.

 The increase in dust collection efficiency is due to the installation of a central and peripheral nozzle and a gas flow swirl in the apparatus. The curler forms a swirling gas flow and, under the action of the resulting centrifugal force, the dispersed particles move to the periphery of the cylindrical chamber. The central nozzle, installed in front of the twist, creates a volumetric spray torch of irrigation fluid. When contaminated gas and atomized liquid come into contact, the latter partially evaporates and the gas cools. The resulting gas suspension is separated by centrifugal forces arising from the rotation of the stream. The separated sludge is washed off by the liquid sprayed by the peripheral nozzles installed in each flow section after the curler. In addition, when a gas suspension comes into contact with a cold solution of barium carbon dioxide (UB), further cooling of the flue gases and the enlargement of unseparated dispersed particles occur due to condensation of water vapor on the latter.

 The connection of the cylindrical chamber with an inclination to the cyclone, taking into account the runoff of the sludge, ensures the dispersion of particles into the sludge collector, which also increases the dust collection efficiency of the device.

 The optimal geometry of the gas flow swirl blades forming the flow sections leads to a decrease in the hydraulic resistance of the device. The choice of the optimal geometry of the twist blades is due to the fact that each blade in the input section has a rectangular flat shape, then gradually turning into a parabolic one. The blades are bent so that the greater side touch along the entire length of the inner surface of the housing and are rigidly attached to it, twisting the gas flow.

 In addition, the bubbler-vortex apparatus can be used both as an independent dust collecting device and can be installed in the flues of the dust collecting system in order to save material resources and floor space of production facilities.

 The invention is illustrated by drawings: in Fig.1 is a longitudinal section of a bubble-vortex apparatus; figure 2 - view And in accordance with figure 1; figure 3 is a General view of the twist.

 The bubble-vortex apparatus in accordance with FIGS. 1 and 2 comprises a cylindrical chamber 1 with an inlet pipe 2. In the cylindrical chamber 1 a gas flow swirl 3 is installed, which is, in accordance with FIG. 3, a pair of intersecting planes forming four blades 4. The blades 4 form the flow sections 5. In the bubbler-vortex apparatus, a central nozzle 6 is installed in front of the gas flow swirl 3, and peripheral nozzles 7 are located in each flow section 5 after the swirl 3. the inlet pipe 2 and the cyclone 8, the cylindrical chamber 1 has connecting flanges 9. The dispersed particles are removed from the cylindrical chamber 1 by means of a pipe for the transfer of sludge 10 into the sludge collector 11.

 The bubble-vortex apparatus operates as follows.

 Dusty gas is supplied to the cylindrical chamber 1 through the inlet pipe 2, where the curler 3, using the blades 4 forming the flow sections 5, deflects the flow and gives it a rotational movement. Under the action of the resulting centrifugal force, the dispersed particles move to the walls of the cylindrical chamber 1. To improve the conditions for gas purification, one central 6 and four peripheral 7 nozzles are installed before and after the curler 3, into which the irrigation fluid is supplied. When gases and liquids come into contact, the latter partially evaporates and the gas cools. The resulting suspension is separated by centrifugal force arising from the rotation of the flow. The spray jet of coolant formed by the central nozzle 6 (along with the action of centrifugal forces) contributes to the outflow of dispersed particles from the central zone of the cylindrical chamber 1, which reduces the particle path to the wall and reduces the separation time. The optimal geometry of the blades of the twist 3 is ensured by the fact that at the inlet section the blades 4 have surfaces of a rectangular planar shape, turning to the output section into parabolic. In this case, the blades 4 are bent and, for the most part, touch the inner surface of the cylindrical chamber 1 and are rigidly attached to it along their entire length.

The separated sludge is washed off by the liquid sprayed by four peripheral nozzles 7 installed in each flow section 5 after the curler 3, and by means of the inclination of the cylindrical chamber 1, it is transported through the overflow pipe of the sludge 10 into the sludge collector 11. The inclination angle of the cylindrical chamber 1 is selected experimentally within 5- 8 o , sufficient to drain the sludge. When a gas suspension comes into contact with a cold irrigating liquid, further cooling of the gas to be purified and enlargement of unseparated dispersed particles occurs due to condensation of water vapor on the latter. Subsequent separation of the suspension occurs in cyclone 8 (attached to the cylindrical chamber 1 by means of flanges 9), from where the sludge also enters the sludge collector 11.

Experimental studies were carried out on a bubbler-vortex apparatus with a diameter of 1.1 m, in the cylindrical chamber of which a twist was installed with a ratio of input and output linear dimensions of the blades of 0.73. Flue gases from kiln furnaces of the furnace furnace with a temperature of up to 660 o C and a solids content in the range of 50-75 g / m 3 entered the flue. The size of the dispersed particles is from 0.01 to 0.4 mm. A barium carbonate solution was used as an irrigation liquid, since, along with other properties, barium carbonate reduces corrosion in a bubble-vortex apparatus. The specific flow rate of the irrigating liquid was 0.00075-0.0001 m 3 / m 3 of gas, with 20% of this flow being supplied to the central nozzle.

 It was found that the hydraulic resistance of the apparatus does not exceed 150 Pa, the dust collection efficiency for particles with a size of 0.01 mm is not lower than 95%.

 The proposed bubble-vortex apparatus allows to increase the efficiency of purification of exhaust gases and improve environmental protection.
