one

The invention relates to a gas cleaning technique and can be used for wet scrubbing of gas (air), as well as an absorber in any industry where cleaning of emissions or gaseous products is required.

A venturi tube with an adjustable throat section is known, including an irrigation system, a drainage vane, and an axially adjustable axially adjustable cone insert with a stem and a guide located in a diffuser. An I-housing is installed outside the guideline coaxially with it.

Disadvantages of this device

are, the lack of turbulence in the process of mixing the gas flow with the irrigating fluid before it enters the throat of the Venturi tube, the ineffective solution to the problem of separation of droplets and in particular the lack of adjusting the cross-section of the swiveling device of the socket type, the unreliability of the displacement unit and greater device height.

The closest to the technical essence of the invention is a cleaning device having a housing, an inlet and outlet nozzles for gas, a cylindrical contact chamber, an irrigation device located in the inlet nozzle, a conical insert mounted on a vertical displacement rod, cent centrifugal drip catcher, clarifier C23.

  The disadvantages of the known device are the absence of turbulence in the process of mixing the gas stream with the irrigating fluid and its large dimensions.

The purpose of the invention is to improve cleaning efficiency and reduce device height.

The goal is achieved by the fact that in a turbulent cleaning device having a housing, an inlet and outlet for gas, a cylindrical contact chamber, an irrigation device located in the inlet nozzle, a coaxially mounted conical insert fixed on a rod moving along the vertical, a centrifugal drift eliminator, a sump the conical insert is provided with a plate with twisting spiral ribs made with blades at the ends. In this case, the conical insert is installed with the expanding part downwards, the inlet connection is made adjacent to the top of the contact chamber.

In addition, the inlet can be made adhering to the bottom of the contact chamber, over which the cone insert is installed, with the expanding part upwards, while the sump is equipped with an overflow tray connected by a diversion channel with irrigation devices. The device is equipped with a divider installed in the inlet branch pipe and dividing it into two canapes, meeting each other adjacent to the contact chamber in involute mode. FIG. 1 shows the proposed cleaning device, a general view in section; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a device with closed fluid circulation, a general view in section; in fig. 5 v section BB in FIG. 4. The device with the annular regulation. The pink gap contains a center housing, a drift catcher 1 with an inlet 2 and an outlet 3 with nozzles. Inside the housing 1 there is a cylindrical contact chamber 4 with an expandable diffuser 5, in which a conical insert with a plate 7 having twisting spiral pe6pia 8 with blades at the ends is coaxially spaced. At the same time, the annular adjustable gap between the cone insert 6 with the plate 7 and the diffuser 5 fweeT is the optimum angle of the taper of the meldu plate 7 and the diffuser 5 of the contact chamber 4 within 0-15. The rod 9 of the conical insert 6 passes through it and is supplied with a guide. 10 with two supports 11 and 12 at the ends located outside the apparatus. The irrigation device consists of two rows of nozzles 13 installed in the splitter 14, which divides the inlet 2 into two channels oppositely connected to the chamber 4 according to the involute. The discharge pipe 15 is located in the lower conical part of the drift catcher I. When the circulation of irrigation fluid is closed (Fig. 4). the cone insert 6 with the plate 7 is installed with an expanding part upwards the contact chamber — the chamber 4 is located under the cone insert 6; They are implemented in the form of a distribution outlet duct 18 mounted on the lid of the inlet nozzle 2 and communicating with it through a series of holes 19. 9 passes through a tapered insert. Lower hour of the rail 10 of the rod 9 1. 4) placed in the pipe 20. The inlet 2 (Fig. 4) is equipped with a drainage pipe 21, the Device operates as follows. The contaminated gas (air) penetrates into the inlet 2, is divided by the divider 14 into two directional flows irrigated by the nozzles 13, and then enters the contact chamber 4. In the latter, intensive turbulent mixing of the gas with the spray liquid and their coagula occurs. qi When gas enters the annular gap formed by the diffuser 5 and the conical insert 6, the flow rate increases significantly with a significant increase in turbulent mixing. The cleaning efficiency is regulated by moving the rod 9 of the conical insert 6 vertically, which gives a change in the cross section of the annular gap. When gas is projected at the turning point formed by the plate 7 and the diffuser 5, the liquid drops move to the lower part of the annular gap in the zone of twisting spiral ribs B. After the turn, the gas velocity decreases and the drops strengthen. The exit from the annular gap is discarded by spiral ribs 8 with blades tangential to the inner surface of the walls of the casing of the centrifugal drip catcher I. Separated; sludge drops flow down the lower part of the housing 1 and release through the drain pipe 15, and very hot air, exits through the outlet pipe 3. When the fluid is circulating (Fig. 4), the contaminated gas (air) enters the inlet pipe 2, in which its irrigation from the distribution outlet 18 goes. Next, the gas enters the bottom of the contact chamber 4, from it into the annular gap between the diffuser and the cone insert 6, and after twisting it is thrown into the drip pan 1. The scoop (spent gas escapes through the nozzle 3. particles are deposited in its bottom parts and outputs through the drain pipe 15. Clarified Room from the upper part of the sump 6 enters the overflow tray 17, and from it through the distribution outlet channel 18 through the holes in the gas.

Due to the proposed design features of mycTpoftctBH, i.e., the execution of an involute countercurrent gas supply to the contact chamber and the irrigation of gases before meeting the flows, the intensity of turbulent mixing is high. Overmolding is increased in the annular gap by increasing the gas velocity and curvature of the flow before leaving the annular gap. Intensive swirling of threads with the help of twisting blades at the exit from the adjustable annular gap provides effective separation of liquid droplets ..
