Description

(54) DEVICE FOR GAS CLEANING

one

The invention relates to the separation of impurities from gases, air or vapors using a liquid as a secondary agent and can be used in the building materials industry, chemical,

metallurgical and other sectors of the national economy.

A foam scrubber is known, consisting of a casing within which the horizontal working grille (one or more) is interrupted. The grille has round or slit holes with a certain free section. A stabilizer penjj is mounted on the lattice, which is a honeycomb lattice of vertically arranged plates 1.

The closest to the proposed technical essence and the achieved 20 result is a device for cleaning gases, including a housing with inlet and outlet nozzles for

liquid and gas, gazorassfeediteliukg ggaptku, consisting of two installed one above the perfo f1Iirovannyh plates C23 ..

The disadvantage of these piezoelectric gas cleaners is that the level of cleaning in them

: is achieved by reducing the flow area to the gas distribution grids. At the same time, the productivity of the apparatus decreases and the hydraulic resistance sharply increases, which is associated with significant ekshuataoiovn and energy costs.

The purpose of acquisitions is to reduce the cost of the gas cleaning process and increase its efficiency.

Claims (2)

. The supply chain is achieved by the fact that a gas cleaning device, including a housing with inlet and outlet nozzles for liquid n gas, has a gas distribution grid. of the two, perforated plates, which are scarcely yad, are equipped with 1 × 1 (m material, p aaiviement HbiM between the plates, while the plates are made with U-shaped corrugations and partially or completely immersed in the housing. Perforated plates of a wave-like shape of the same profile increase the the capacity of the apparatus, i.e., increase its productivity, reduce the hydraulic resistance, and, accordingly, the power consumption. At the same time, increase the contact surface of the liquid and gaseous phases. Filling the cavity between the yayotin granulated material creates conditions for a continuous change in the direction of the gas flow (when flowing around 1X Granules irregularly deformed), which increases the efficiency of gas cleaning. Partial or complete immersion of the lattice into the absorbing liquid eliminates the need for its intensive irrigation, which reduces the flow rate water on the gas cleaning., Fig. 1 schematically shows a dust collector, a vertical section; in fig. 2 — node I in FIG. 1 enlarged. The device consists of a housing 1, partially filled with a liquid, with an inlet pipe 2 for introducing a contaminated gas and an outlet pipe 3 for a view of the cleaned gas. Inside the casing 1, a gas distribution valve 4 is installed, consisting of two perforated plates 5 of a wave-like shape, mixed vertically relative to each other. The cavity formed between the plates is filled with granulated material 6. The gas diffuser grate 4 is immersed in the absorption liquid, which is fed into the apparatus through the nozzle 7. The waste liquid is discharged through the shutter 8. In the upper clock, the apparatus is installed kappeotdeggel 9. The device works as follows. Ochaschae gas through the inlet pipe 2 dsh enter the contaminated gas, the gas enters the sublattice space, displacing part of the absorption liquid on the grid 4, forms over it a layer of highly turbulized foam. The passage through the holes of the perforated plates 5 and the granulated material b gas stream is crushed into separate jets. Continuously changing direction (the flow around the randomly arranged granules) and in contact with the foam layer, the gas flow is cleaned. The cleaned gas is directed to the droplet separator 9 in which the absorption liquid is separated, carried away in the form of splashes by a gas stream from the foam layer, and is released from the device by you. the inlet pipe 3. The absorption liquid, as it is polluted, is removed from the apparatus by means of the shutter 8. The advantage of the proposed gas purification device as compared to the known ones is that the efficiency of gas cleaning is increased while reducing hydraulic resistance, which leads to a reduction in energy costs. In addition, the capacity of the apparatus for gas to be purified is increased and the consumption of the absorption liquid is reduced. Claims An apparatus for cleaning gases comprising a housing with inlet and outlet nozzles for a liquid and a gas, a gas distribution grid consisting of two perforated plates installed one above the other, with the exception of the chain process of gas cleaning and improving the efficiency of the process, the device is equipped with granular material placed between the plates, and the plastics are filled with U-shaped corrugations and partially or completely immersed in a liquid., i: Information sources, Considered during examination 1.
