Description

The invention relates to techniques for the purification of gas from particles in a price field (54) (57) Khoi of tractive forces. The purpose of the invention is to reduce the size and hydraulic resistance of the cyclone. Gas (solid arrow) with dust (dashed arrow) enters the cyclone body I. Passing between the blades of the twist 2, the gas acquires a rotational movement. Due to centrifugal forces, the dust is thrown to the walls of the housing 1, by inertia rushes down and through the intervals between the pipelines of the node 4 is removed from the cyclone through the hole 3. The purified gas from the central part of the cyclone is discharged through the pipelines to the consumer. The location of the axes of the pipelines perpendicular to the axis of the cyclone; their arrangement with tiers with an offset relative to the pipes of adjacent tiers allows for a large exit area for the flow of purified gas and thereby reduce the dimensions and hydraulic resistance. 1 s P. f-ly, 3 ill.

figure 1

The invention relates to techniques for dry cleaning of gases from particles in the field of centrifugal forces and can be used in almost all sectors of the economy. ,

The purpose of the invention is the reduction of dimensions and hydraulic resistance.

In FIG. 1 shows a cyclone, a longitudinal section; in FIG. 2 — section A — A in FIG. 1; in FIG. 3 - section B — B in FIG. 1.

The cyclone contains a housing 1, twisting - 1 body 2, a discharge opening 3, a node 4 for removal of the cleaned stream, made in. in the form of straight pipelines 5, the input ends of which are located between the wall and the longitudinal axis 6 of the housing, while the pipelines can be placed in tiers with ¹ angular offset relative to the pipelines of adjacent tiers.

The cyclone works as follows.

Gas (solid arrow) with dust (dashed arrow) enters the cyclone inlet. Passing between the blades of the twist, it acquires a rotational movement. In a rotating dust and gas flow, Dust particles are thrown onto the inner walls of the housing 1, move under the action of gravity and inertia down to the conical part through the gaps between the pipelines 5 and are discharged from the cyclone through the opening 3. The purified gas is discharged from the central part of the cyclone through pipelines 5 to the consumer. Reduced dimensions and hydraulic resistance allow ^{3 to} install the proposed cyclones indoors and integrate them into various equipment (steam generators of boiler plants, hydrocarbon conversion reactors, etc.). This allows you to save scarce material, energy, reduce capital and operating costs. Due to the ability of the proposed cyclone to capture coarser fractions of the dispersed phase and to miss its small application, for example, for cleaning gases after dryers, it will increase the yield of the target product. When cleaning the generator gas at CCGT-250, due to this property, underburning is captured, which, when returned to the reactor furnace, will provide fuel economy.

The invention relates to a technique for the dry cleaning of gases from particles in a field of centrifugal forces and can be used in almost all sectors of the national economy. The purpose of the invention is to reduce the size and flow resistance. FIG. 1 shows a cyclone, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1. The cyclone includes a housing 1, a twister 2, a discharge opening 3, a node 4 for discharging the cleaned flow, made in. as direct pipelines 5, the input ends of which are located between the wall and the longitudinal axis 6 of the housing, while the pipelines can be placed in Rus with an angular displacement relative to the pipelines of adjacent Rus. The cyclone works as follows. Gas (flat arrow) with dust (dotted arrow) enters the cyclone inlet. The passage between the blades of the spinner, it acquires a rotational motion. In the rotating dust and gas flow, dust particles are thrown onto the inner walls of the housing 1, moving under the action of gravity and inertia down into the conical part through the gaps between the pipelines 5 and removed from the cyclone through the opening 3. The purified gas from the central part of the cyclone through pipelines b is removed to the consumer. The reduced dimensions and hydraulic resistance make it possible to install the proposed cyclones inside the premises and embed them inside various equipment (steam generators of boiler plants, hydrocarbon conversion reactors, etc.). This saves scarce material, energy, and reduces capital and operating costs. Due to the ability of the proposed cyclone to capture the coarser fractions of the dispersed phase and to skip smaller applications, for example, to purify gases after particles will increase the yield of the target product. When cleaning the generator gas at CCGT-250, due to this property, underburning is caught, which, when returned to the reactor furnace, will provide fuel savings. Claim 1. Cyclone, comprising a housing, a curler, a clean flow outlet assembly connected by an outlet to the side surface of the housing, a discharge opening, characterized in that, in order to reduce the size and flow resistance of the cyclone, the discharge assembly is made in the form of straight pipelines, the inlet pipes the ends of which are located between the wall and the longitudinal axis of the housing. 2. A cyclone according to Claim 1, characterized in that the pipelines are installed in Rus with an angular displacement of adjacent Rus.
