SU1009160A1 - Cyclone-cooler for high temperature dusted gases - Google Patents

Description

The invention relates to the field of dust removal and heat recovery of high-temperature gases and can be used in the chemical, petrochemical and other areas of the national economy.

Known cyclone-coolers of high-temperature dusty gases, containing a shielded cylindrical body with tangential nozzles gas supply and led through the cover of the outlet pipe.

The disadvantage of these cyclones is low cooling efficiency and

about

reliability due to small surface

W) heating and out of order of the outlet.

Partially, these drawbacks are set in a cyclone-cooler of high-temperature dusty gases containing

a shielded cylindrical body with tangential nozzles for gas supply and inserted through the housing cover with an outlet nozzle provided with a tubular screen on the inner surface.

The disadvantage of this device is the reduced efficiency of cooling because of the insufficient number of heating surfaces and the passage of a part of gas through leaks in the walls of the outlet nozzle.

The purpose of this invention is to eliminate these drawbacks.

This is achieved by the fact that the cyclone is provided with screens made of tube-shaped pipes and an annular distributing chamber placed outside the housing with supply pipes, the outlet of the housing is made with a gas-tight wall, and its tubular screen is formed by vertical pipes with upper discharge and lower supply ring headers the latter of which is connected to the supply pipelines of the separating chamber, and the said screens are radially mounted in the cavity of the branch pipe, and their shaped pipes are connected to the screen pipes.

In addition, the dispensing chamber may be installed above the screen outlet manifold, and its supply pipelines may be installed in the cavities of the vertical pipes of this screen.

FIG. 1 shows the proposed cyclone-cooler, a longitudinal section, the first option; in fig. 2 shows section A-A in FIG. 1; FIG. 3 — node I in FIG. one; in fig. 4 longitudinal cyclone-cooler, longitudinal pai3pe3, the second option; in fig. 5 is a section BB in FIG. four; in fig. 6 is a sectional view BB in FIG. four; in fig. 7 - node And in FIG. four; in fig. 8 - node P1 in FIG. four.

The cyclone-cooler of high-temperature dusty gases contains a cylindrical body 2 shielded by pipes 1 with tangential pipes 3 supplying gases and introduced through a cover

4 cases 2 with an outlet pipe 5, fitted on the inner surface of tubular pipes, with a screen formed by straight pipes b and 7 with upper discharge and lower inlet ring headers 8 and 9. In cavity 10 of the outlet nozzle

5 radially installed screens 11 and 12, made of shaped pipes, which are connected to the pipes 6. The lower sub collector 9 is connected to the inlet pipe 13 of the ring distributing chamber 14 located outside the housing 2. The outlet 5 is made with a gas-tight wall.

The screen pipes 1 of the housing 2 are connected to the supply and discharge ring collectors 15 and 16. The sections of the supply pipe 13 located in the housing 2 are covered with insulation 17. The distribution chamber 14

equipped with drainage pipes 18. Screens 11 and 12 are made to increase the filling of the cavity 10 of the outlet nozzle 5 with a different transverse size and are set in an alternate p | e.

Distributing chamber 14 can be installed above the outlet manifold 8, and its

supply pipelines 13 are set up in

10 cavity vertical pipes 6. Case 2 is equipped with a pipe 19 for removal of dust. The outlet 5 is made with the possibility of removal.

Cyclone cooler works as follows.

High-temperature dusty gases through the tangential nozzles 3 are fed into the housing 2, moving from top to bottom along a spiral line in the annular gap between 20 DU housing 2 and the outlet nozzle 5, where due to centrifugal forces dust separates to the walls of the housing 2. turn 180 ° and exit from the cyclone through the cavity 10 of the outlet nozzle 5. Separate 25 the dust is removed from the housing 2 through the nozzle 19. As it moves through the housing 2 and the outlet 5, the gases release their heat to the screen pipes 1, 6 and 7 and screens 11 and 12. Heat of gases transmits Water

30 incoming into the screen tubes 1 through the inlet manifold 15, and into the screen tubes 6 and 7 through the dispensing chamber 14, the inlet pipelines 13 and the inlet manifold 9. In the screens 11 and 12, water flows

35 through vertical pipes 6.

When water is heated, steam is generated. which is discharged in the form of a steam-water mixture through the exhaust manifolds B and 16. The cyclone with the screens 11 and 12 installed in the cavity 10 of the outlet nozzle 5 increases the heat exchange surface, which increases the cooling efficiency of the gases. The same contributes to the implementation of the walls of the outlet nozzle 5 gas-tight.

45 which ensures the passage of all the gas through the nozzle 5, its screen in the form of vertical pipes 6 and 7 with ring headers 8 and 9, and screens 11 and 12 in the form of -shaped pipes connected to the pipes 6. maximum number of heating surfaces while ensuring simplicity of construction and reliability.

The reliability is also enhanced by the fact that the cyclone is provided with a dispensing chamber 14 located outside the housing 2, which ensures an even supply of water to the lower supply manifold 9.

The placement of the dispensing chamber 14 under the OVERDOWN of the collector 8, the duct and their pipelines 13 about the cavity of vertical pipes 6 increases the compactness of the cyclone and improves

repair, during which the exhaust pipe 5 is removed from the housing 2.
