Description

The invention relates to the technique of wet gas cleaning from fine aerosols and substances in the vapor-gas state and can be used in any branch of the national economy.

A device for wet gas cleaning is known, comprising a housing with gas inlet and outlet nozzles and a washing liquid, inside of which is placed a dynamic atomizer in the form of a rotor made of two disks with a washing liquid distributor between them. At the surface of the distributor, made perforated, rods are mounted inclined to the axis of rotation, on which til threads are attached. A disadvantage of the known device is the low efficiency of gas purification from fine aerosols and substances in the vapor-gas state. This is caused by the fact that the gas to be cleaned and the washing liquid interact with each other in the working area of the apparatus with large volumes, which does not allow to create high-quality contact between them.

The closest to the described invention on the technical essence and the achieved result is

a device for wet gas cleaning comprising a housing with gas inlet and outlet nozzles, a perforated cylinder is installed inside the body with the possibility of rotation, equipped with a liquid supply nozzle, while the contact elements t2 1 are installed on the cylinder surface.

The disadvantage of the prototype is

10 low efficiency of gas purification from fine aerosols and substances in the vapor-gas state due to the interaction of gas with the washing liquid of large volumes in the working area of the apparatus.

The aim of the invention is to increase the efficiency of gas cleaning.

The goal is achieved by the fact that in the device for wet

2b of gas cleaning, including a housing with inlet and outlet pipes for the pelvis, a perforated cylinder is rotatably installed inside the housing, equipped with an inlet pipe

25 liquids, with contact elements installed on the cylinder surface, the latter made in the form of flexible capillaries.

Claims (1)

The proposed implementation of the device for wet gas cleaning in comp. with the known device provides for the following functions: divider of gas flow to small streams by means of communication of the cavity of the perforated pipeline with the cavity of the gas inlet / high-quality gas contact with liquid and low-flow gas in the flooding mode, as well as the ultrathin atomizer liquids due to shock interaction with the gas — all this by placing flexible capillaries on the perforated pipeline and aligning the openings of their channels with the openings of the perforation. . FIG. 1 shows a schematic of the proposed device; in fig. 2, section A-A of FIG. 1. The proposed device for wet gas cleaning includes a cylindrical housing 1. with a 2 inlet pipe and a pelvic outlet 3, a discharge 4 for sludge. Inside the housing 1, a perforated / 5th perforated cylinder 5 is installed, provided with a connection b for supplying liquid. The cylinder has strong and contact elements in the form of flexible capillaries 7, the channels of which are aligned with the perforations of the cylinder 5. The cavity of the gas inlet nozzle 2 communicates with the cavity of the perforated cylinder 5. The proposed device works as follows. When the cylinder 5 rotates and the fluid flows through the nozzle b into it, it is evenly distributed over the entire inner surface of the cylinder 5. Under the influence of centrifugal forces caused by the rotation of the cylinder 5, the liquid flows through the perforation holes into the capillary channels 7, where the velocity moves along the channel of the capillary 7 to its end. The dusty gas through pipe 2 also enters the cylinder 5 and, evenly distributed, is directed to the channels of the capillaries 7. In the channels of the capillaries 7, the gas to be cleaned and the washing liquid actively interact with each other, and the intensity of interaction increases sharply from the beginning to the end of the capillaries This is due to the fact that the circumferential speed of movement of the capillaries 7 increases toward their ends. At the beginning of the capillaries 7, the relative speed of movement of gas and liquid will have high values, since the density of the liquid is three times higher than the density of the gas for now. Therefore, the gas will be turbulized in kangshe and will intensify the mass flow processes between the liquid and the gas. High-quality contact will be provided by small gas flow in the capillaries 7. At the exit from the channels of the capillaries 7, the dust-gas-liquid flow is compressed, and then expands according to the laws of motion of the free gas jet. In this case, the liquid leaves the capillaries 7 at high speed. motion and collides with the gas (which is located in the annular space between the housing 1 and the cylinder 5). This causes the fluid to be crushed into ultrafine-sized particles, which then move at high speed in an expanding gas stream exiting the capillary channels 7. Consequently, the movement of the gas to be purified and the washing liquid in the channels of the capillaries 7 occurs in the choking mode, and at the exit of the channels the gas is filtered through a very dense curtain of liquid particles of superfine size. In the annular space of the apparatus formed by the cylinder 5 and the housing 1, the gas carried by the rotating capillaries 7 is also in rotational motion. Therefore, the sprayed liquid, subjected to centrifugal forces, coagulates with dust particles and deposits on the inner wall of the housing 1 and as a slurry flows into the lower part of the housing 1, where it is removed through the nozzle 4. Increase the degree of gas cleaning and reduce the size of the boundary grain (t the particle diameter of the aerosols captured in the apparatus at 100%) as follows; changing the internal diameter of the capillary channel and its wall thickness; changing the circumferential skbrost of rotation of the capillaries; change the density of the gas reflux in the capillary channels. The proposed device can independently transport the gas to be cleaned, since the beginning and end of the capillaries 7 have different peripheral velocities, which induces the movement of gas in the channels of the capillaries 7, the cream of this, the movement of the liquid in the channels and its release into the cavity of the housing 1 causes an ejection effect. The effect of using the claimed invention is to create highly efficient and cost-effective devices for ecological systems.
