Technical field
The utility model is related to coal gas dust removal of converter technical field, more particularly to a kind of annular gap scrubber.
Background technology
In pneumatic steelmaking dust pelletizing system, annular gap scrubber is the core equipment of wet dedusting.Converter gas is sprayed through supersaturation
Drench tower by after mild rough dedusting, annular gap scrubber refined dedusting is entered with the speed of 100m/s or so.Since flue gas enters aditus laryngis
Speed is larger, and forms certain corner cut with taper regulating valve, and taper regulating valve is highly prone to the erosive wear of flue dust and damages,
Dust removing effects are influenced, or even regulating valve is worn out, makes its loss of pressure regulatory function.
Although annular gap scrubber has done meticulous consideration in design, keep its interior flow field more uniform, non-dedusting resistance damage
Lose smaller, but the inlet air flow at its aditus laryngis is with inner cone wall surface that there are still the higher regions of the angle of shock.Due to entrance coal gas dust content
Amount is high, and particle diameter and kinetic energy are big, and the shock zone rate of wear is made to be exceedingly fast.The technique of steel-making dedusting is determined to use as a servant in stove and be examined
Taper regulating valve is handled and replaced when repairing, so the continuous abrasion of some specific region, accelerates the speed of crack propagation
Degree.
In actual production, most incident to be exactly that overground phenomenon is locally occurring for annular gap scrubber, once occur small
Crackle will drastically expand as hole.During each overhaul is replaced, an often annular gap scrubber, other parts or complete
Alright, but has there is broken hole in part, it has to replace spare part, cause great cost loss.

Regulating valve is arranged in the annular gap scrubber shell；It is adjusted by rotation device, is connect with the regulating valve；Up and down adjustment fills
It sets, is connect with the regulating valve across the device that is adjusted by rotation.
Further, the regulating valve is tapered regulating valve.
Further, the device that is adjusted by rotation includes：Axle sleeve is connect with the regulating valve.
Further, the up and down adjustment device includes：Adjusting rod is adjusted by rotation device and the adjusting across described
Valve connects.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages：
Since regulating valve is arranged in annular gap scrubber shell, it is adjusted by rotation device and is connect with regulating valve, so, it adjusts
Valve can be rotated by being adjusted by rotation device, the vertical axial rotation of annular gap scrubber be realized, to avoid circular seam washing
General ability portion and converter gas there is a phenomenon where friction ensure setting in the time between overhauls(TBO) to improve the service life of regulating valve
Standby normal operation is adjusted by rotation device and is connect with regulating valve since up and down adjustment device passes through, so, upper downward can be passed through
Regulating device drives regulating valve to move up and down, and can control the flow velocity of converter gas, while can change converter gas shock zone,
It avoids part overground, improves the service life of regulating valve.
Description of the drawings
Fig. 1 is the structural schematic diagram for the annular gap scrubber that the utility model embodiment provides；
Fig. 2 is the connection diagram for being adjusted by rotation device and the regulating valve that the utility model embodiment provides.
Specific implementation mode
Referring to Fig. 1-2, the utility model embodiment provides a kind of annular gap scrubber and includes：Annular gap scrubber shell 1 is adjusted
Section valve 2 is adjusted by rotation device 3 and up and down adjustment device 4.
The regulating valve 2 is arranged in the annular gap scrubber shell 1.
The device 3 that is adjusted by rotation is connect with the regulating valve 2.
The up and down adjustment device 4 is adjusted by rotation device 3 described in and is connect with the regulating valve 2.
The application specific implementation mode is adjusted by rotation device and adjusts since regulating valve is arranged in annular gap scrubber shell
Valve connection is saved, so, regulating valve can be rotated by being adjusted by rotation device, realize the vertical axial rotation of annular gap scrubber
Turn, to avoid annular gap scrubber part with converter gas there is a phenomenon where friction, to improve the service life of regulating valve, protect
The equipment normal operation in the time between overhauls(TBO) is demonstrate,proved, device is adjusted by rotation since up and down adjustment device passes through and is connect with regulating valve, institute
Regulating valve can be driven to move up and down by up and down adjustment device, the flow velocity of converter gas can be controlled, while can change
Converter gas shock zone avoids part overground, improves the service life of regulating valve.
The structure of regulating valve is discussed in detail.
The regulating valve 2 is tapered regulating valve.
The structure for being adjusted by rotation device is discussed in detail.
The device that is adjusted by rotation includes：Axle sleeve 3-1.
The axle sleeve 3-1 is fixedly connected with the regulating valve 2.Specifically, in the present embodiment, the axle sleeve 3-1 is logical
It crosses bolt to be fixedly connected with the regulating valve 2, in other embodiments, the axle sleeve 3-1 can be otherwise such as pivot pin
It is fixedly connected Deng with the regulating valve 2.The regulating valve 2 can be rotated by the axle sleeve 3-1, realize annular gap scrubber
Vertical axial rotation, to avoid annular gap scrubber part with flue dust straight hair gave birth to friction the phenomenon that, to improve regulating valve
Service life ensures the equipment normal operation in the time between overhauls(TBO).
The structure of up and down adjustment device is discussed in detail.
The up and down adjustment device includes：Adjusting rod 4-1.
The adjusting rod 4-1 is adjusted by rotation device 3 described in and is fixedly connected with the regulating valve 2.Specifically, at this
In embodiment, the adjusting rod 4-1 is adjusted by rotation device 3 described in by bolt and is fixedly connected with the regulating valve 2,
In other embodiments, the adjusting rod 4-1 pass through it is described be adjusted by rotation device 3 can otherwise such as pivot pin with
The regulating valve 2 is fixedly connected.
When the adjusting rod 4-1 drives the regulating valve 2 to move upwards, make the valve body of the regulating valve 2 and the ring
The gap stitched between washer shell 1 reduces, and the speed of converter gas is made to increase, and accelerates the progress of work, has changed simultaneously converter
The shock zone of flue gas avoids part overground, improves the service life of regulating valve.
When the adjusting rod 4-1 drives the regulating valve 2 to move downward, make the valve body of the regulating valve 2 and the ring
