Description

The invention relates to techniques for wet dust collection and can be used in chemical, textile, food, light and other industries for the purification of dusty gases.

Known element nozzle apparatus for wet cleaning of dusty air according to the patent of the Russian Federation No. 2490053, class. B01D 47/06, comprising a housing with nozzles for dusty and purified gas, an irrigation device, support grids between which the nozzle is located, and a device for removing sludge, and the nozzle is made in the form of cylindrical rings, on the side surface of which there are two cuts in the direction parallel to the generatrices of the cylindrical surface, and the slot in the direction perpendicular to the axis of the ring, and the slots, closing, form a U-shaped slot, the resulting petals are bent in the direction of the axis of the ring, while on the left the petals perform bends in the form of shelves in the direction perpendicular to the axis of the ring, and similar petals are spaced 90 ° apart from the previous ones, while the nozzle elements are perforated (prototype).

The disadvantage of the prototype is the relatively low efficiency of the dust collection process due to the underdeveloped surface of the nozzle.

The technical result is an increase in the efficiency and reliability of the dust collection process due to a more developed nozzle surface.

This is achieved by the fact that the nozzle element for the scrubber, comprising a housing with nozzles for dusty and purified gas, an irrigation device, support grids between which the nozzle is located, and a device for removing sludge, are made in the form of at least three hemispherical coaxially located surfaces connected between themselves with a gap by means of a fastening element through axisymmetrically arranged spacing elements in the form of rings, and between hemispherical surfaces are fixed to spacing elements Hm corrugated elements shaped forming surface, equidistant hemispherical surfaces.

Figure 1 shows a nozzle scrubber with transverse irrigation, figure 2 shows a countercurrent nozzle scrubber, figure 3 is a diagram of a nozzle element.

A nozzle for a scrubber comprising a housing 1 (FIG. 1 and FIG. 2) with nozzles 2 and 3 for dusty and purified gas, an irrigation device 6, support grids 4, between which a nozzle 5 is located, and a device for removing sludge is shown in FIG. .3.

To increase the degree of purification of the gas stream from dust or the target component by increasing the contact area of the dusty stream with the nozzle 5 (Fig. 3), the nozzle element is made in the form of at least three hemispherical coaxially located surfaces 7, 8, 9, interconnected with the gap by means of a fastening element, for example in the form of a bolt 10 with a nut 11, through axisymmetrically arranged spacing elements 12 and 13, for example in the form of rings. Between the hemispherical surfaces 7, 8, 9 corrugated elements 14 and 15 are fixed on the mounting elements, having the form of a forming surface that is equidistant to hemispherical surfaces. Corrugated elements 14 and 15 can be made perforated (not shown in the drawings).

The mounting elements 12 and 13 can be made in the form of coil springs (not shown in the drawings).

Hemispherical surfaces of the nozzle element may be perforated.

The nozzle 5 can be made of porous polymeric materials, glass, porous rubber, composite materials, wood, stainless steel, titanium alloys, precious metals.

The nozzle for the scrubber works as follows.

The dusty gas stream enters the housing 1, through the inlet of the dusty gas stream 1, and meets a curtain from the nozzle 5, which is wetted with water or other absorbent from the irrigation device 6. The flow rate of the irrigation fluid in countercurrent nozzle scrubbers is accepted in the range of 1.3 up to 2.6 l / m 3 . In nozzle scrubbers with transverse irrigation for better wetting of the nozzle surface 5, the nozzle layer is inclined by 1 ... 10 ° in the direction of the gas flow. The flow rate of irrigation fluid in them is taken in the range from 0.15 to 0.5 l / m 3 . The dust collection process proceeds in the optimal hydrodynamic mode, since the hydraulic resistance of the nozzle 5 is 20% less than the hydraulic resistance of the outlet pipe 3 of the purified gas. To reduce the vibro-acoustic activity of the apparatus and its metal consumption, as well as increase its reliability, the proposed device provides the following measures: a layer of soft vibration-damping material, for example, VD-17 mastic, is applied to the surface of the parts, and the ratio between the thickness of the metal and the vibration-damping coating is in the optimal range of values: 1 / (2-5 ... 4). To remove sludge, a device is used to remove sludge in the form of a channel in the bottom of the housing or a separate mechanism.

The nozzle scrubber can be used to clean fine dust and humidify air in ventilation units and air conditioning units, as well as in trapping mists, readily soluble dust, as well as in the process of dust collection, gas cooling and absorption of nozzle scrubbers. The effectiveness of the proposed design of the nozzle scrubber increases due to the larger interaction surface of the nozzle in the above processes and when collecting dust particles larger than 2 microns in size is about 95%.
