Description

(54) GAS CLEANING MACHINE

one

The invention relates to the instrumentation of gas cleaning processes by absorption and wet dust removal methods and can be used in the chemical and related industries.

A gas cleaning apparatus is known, which includes a cylindrical body with a tangentially mounted gas inlet, a liquid inlet, a gas outlet, coaxially aligned with the housing, and a gas outlet 1.

The disadvantages of this device is the low phase interaction efficiency and a significant splash of liquid.

The purpose of the invention is to intensify the gas cleaning process by increasing the contact surface of the phases and reducing the splash splash.

The goal is achieved by the fact that a gas cleaning apparatus comprising a cylindrical body with a tangentially installed gas inlet nozzle, a liquid inlet nozzle, a nozzle for exhausting cleaned gas installed coaxially with the body and a nozzle for discharging waste liquid is coaxially mounted outside body.

at the same time, annular slots are made in the housing, and a nozzle for liquid inlet is attached to the shell.

The bottom edge of each annular gap is provided with a plate.

The nozzle for removal of the purified gas is provided with a frusto-conical reflector located coaxially with the nozzle in its lower part, under which there is a separation chamber with a blade swirler and fairing.

Claims (3)

The gas cleaning apparatus includes a cylindrical housing 1 with a nozzle 2 for supplying the gas to be cleaned, installed 15 tangentially to the housing 1. Coaxially with the housing 1. there is a nozzle 3 for exhausting the cleaned gas, and in the lower part the housing 1 is equipped with a nozzle 4 for draining the waste liquid. The housing 1 is equipped with a shell 5 installed outside and coaxially to the core 20 of the I bus, in which the annular slots 6 are made, while the lower edge of each annular gap is provided with an annular plate 7. In the lower part of the nozzle 3, a reflector 8 in the shape of a truncated cone is fixed to under which is placed the separation chamber 9 with the formation of an annular gap 10 between the chamber 9 and the outer surface of the nozzle 3. The separation chamber 9 is equipped with a blade swirl 11 with a fairing 12. The shell 5 is equipped with a nozzle 13 for insertion bones. The device works as follows. The irrigating liquid is introduced into the apparatus through the nozzle 13 into the space between the housing 1 and the shell 5 under pressure, from where it flows through the annular slots 6 into the internal volume of the housing 1 in the form of spatial film curtains overlapping the cross section of the apparatus. The annular plates 7 improve the formation of the film curtains and give them a certain direction of movement. Contaminated (with dust or gaseous components, the gas enters the apparatus through a tangentially installed nozzle 2, which ensures the formation of a swirling gas stream moving in a spiral from top to bottom, meeting liquid film curtains on its way, and disperse them into droplets. Under the action of centrifugal forces of a drop of liquid move to the wall of housing 1, where they are separated to form a downward liquid film, on which dust particles are deposited that are not captured in the zone of intense contact of the phases. the end of the separation chamber 9, the gas rotates 180 ° and the entrance to the separation chamber is twisted with a blade swirler 11 with a fairing 12. The formation of a swirling gas flow in the separation chamber 9 allows to emit uncooled dust particles and liquid droplets from the gas flow which are removed through the annular gap 10 into the working cavity of the apparatus into the dilution zone under the reflector 8. The cleaned gas is discharged from the apparatus through the nozzle 3, and the waste liquid is removed through the nozzle 4. Use mations of the proposed apparatus allows to intensify the gas cleaning process by forming in the inner volume developed phase contact surface of the housing and reduce brazgounos. Claim 1. Gas purification apparatus comprising a cylindrical body with a tangential ° installed gas inlet, a liquid inlet, a gas outlet discharged coaxially with the body, and a waste water dispenser, characterized in that In order to intensify the gas cleaning process by increasing the surface of the contact of the phases and reducing the sprinkling fluid, it is equipped with a shell mounted outside of the housing coaxially, with annular gaps in the housing, and introducing the liquid is attached to the sleeve. 2. An apparatus according to claim 1, characterized in that the lower edge of each annular gap is provided with a plate. 3. The apparatus according to claim 1, characterized in that the nozzle for removal of the purified gas is provided with a reflector in the form of a truncated cone located coaxially with the nozzle in its lower part, under which is installed a separation chamber with a blade swirl and fairing.
