Claims (5)

1. A venturi scrubber comprising a confuser, a neck, a diffuser, an irrigation system, a drip trap, and an irrigation device is placed in the confuser, consisting of a water supply pipe made in the form of two mutually perpendicular sections, one of which is placed axisymmetrically to the confuser, and at its end facing towards the neck, fastened irrigation nozzle, wherein the inlet diameter d converger ₁ and the outlet diameter of the diffuser ₃ d connected respectively to the inlet and outlet trubop gadgets, and the diffuser outlet connected to the discharge pipe is tangentially connected to the lower part of the cylindrical body of the direct-flow cyclone acting as a droplet eliminator, while the axes of the diffuser and the cyclone body are mutually perpendicular, the lower part of the cyclone body being connected to a conical hopper for draining the sludge, and the upper the part is connected to a conical chamber for the removal of purified gas, while the following aspect ratios of a circular Venturi pipe are aerodynamically optimal: neck length

,

,

, where d ₂ is the diameter of the neck; α ₁ is the narrowing angle of the confuser, α ₁ = 15–28 °, α ₂ is the expansion angle of the diffuser, α ₂ = 6–8 °; moreover, at low gas velocities and fine dust, venturi pipes with an elongated neck should be used

, the nozzle of the irrigation system contains a housing with a fitting rigidly connected to the housing, coaxially located in the upper part of the housing and having a cylindrical hole for supplying fluid connected to the diffuser, an axisymmetric housing and the fitting, and to the housing, in its lower part, by at least at least three spokes connected to a spray located perpendicular to the axis of the housing and made in the form of a perforated disk, the spray disk of the nozzle is formed by two surfaces, one of which is facing the diffuser, cr a curved surface, and the line forming this surface is an nth-order curved line, and the second is a plane, the spokes through which the nozzle atomizer disk is attached to the housing are located radially with respect to the axis of the housing and can be made straight in shape and curved, the perforation holes in the nozzle disk have axes intersecting at a point lying on the end surface of the housing and being the center of the largest circumference of the diffuser, the nozzle atomizer is made of solid materials, for example, bid'a tungsten, characterized in that the spokes through which nozzle atomizer disk attached to the body, there are elements of propeller type. 2. The venturi scrubber according to claim 1, characterized in that the nozzle spokes, by means of which the nozzle atomizer disk is attached to the body, are arranged with a bend towards the nozzle axis, while there are also propeller-type elements on the bend section, the direction of rotation of which is opposite to the direction of rotation propeller-type elements located in the part of the spokes before they bend.
