Water treatment unit is all the processing mode using multistage flash distillation Heisui River.Due to containing a large amount of thick slag and coal ash particle in Heisui River,
It is more serious to washing away for pipe-line equipment.It generally takes at present and adds chevron shaped protection against erosion at the piping inlet of hp flash drum Heisui River
Plate, although this device can effectively prevent from washing away, extending the service life of equipment, existing herringbone to a certain extent
Type washes away plate and selects ordinary carbon steel material, running check is needed to replace chevron shaped arc panel, and since its top is opened wide, decompression is dodged
Heisui River steam mixture after steaming will necessarily splash upwards after entering flash tank at a high speed, and pulp water can enter sudden strain of a muscle with flash steam
Steam washer causes the buck solid content in flash steam washer to be substantially increased, makes water quality deterioration, in turn result in follow-up system
Pipe-line equipment wears or blocks, and seriously affects the stable operation of gasification installation.
Invention content
In order to solve the problems, such as present on, the utility model provides a kind of structure design advantages of simple, can be effective
By gas-liquid separation, ensure the water quality of recycling, and the hp flash drum of anti-stop-band liquid that washes away of the Heisui River to pipeline can be prevented.
To achieve the above object, the utility model provides following technical solution：
A kind of hp flash drum of anti-stop-band liquid including tank body, further includes protection against erosion arc panel, the protection against erosion arc panel
To push up flat semicircular plate, Open Side Down, and the semicircular edge of protection against erosion arc panel is welded in inner tank wall, and protection against erosion arc
The center line of the Heisui River inlet tube of the center face tank body of plate, the height of protection against erosion arc panel not less than tank body Heisui River into
Twice of mouth pipe caliber, and the radius of protection against erosion arc panel is not less than the Heisui River inlet tube caliber of tank body.
During use, Heisui River generates steam by tank body entrance and pulp water, steam and pulp water are entered in tank body together,
And the gas-liquid mixed media of steam and pulp water moved in tank body during collide change after protection against erosion arc panel flow direction to
Lower movement is flowed out from the opening of protection against erosion arc panel, and since liquid motion inertia is larger, pulp water goes out after protection against erosion arc panel can be after
It is continuous to move downward, and steam goes out after protection against erosion arc panel that direction can be rapidly changed and flows up, so as to reach the mesh of gas-liquid separation
, pulp water is prevented in steam enters subsequent flash steam washer, improving water quality.
Preferably, the protection against erosion arc panel inner wall is equipped with protection against erosion protective layer.
Preferably, the protection against erosion protective layer is chromium carbide coating, it can effectively alleviate gas-liquid mixed gas to anti-
The erosion of arc panel is washed away, extends the service life of protection against erosion arc panel.
Preferably, the distance of the Heisui River inlet tube lower edge of the protection against erosion arc panel lower end and tank body is not less than tank body
The half of Heisui River inlet tube caliber can make the tube wall of steam and Heisui River inlet tube of the slag liquid blending agent far from tank body, prevent
To washing away for the tube wall of the Heisui River inlet tube of tank body, the service life of tank body is improved.
Preferably, the protection against erosion arc panel is the flat semicircular plate in top of rounding off.
Compared with prior art, the hp flash drum of the anti-stop-band liquid of the utility model has beneficial effect following prominent
Fruit：
（One）The protection against erosion arc panel of the hp flash drum of the anti-stop-band liquid is welded on the inner wall of tank body, erosion control brush arc
The center line of the Heisui River inlet tube of the center face tank body of shape plate, can will be in tank body by the effect of protection against erosion arc panel
Steam and pulp water separate, achieve the purpose that gas-liquid separation, so as to improve water quality；
（Two）The protection against erosion arc panel inner wall is equipped with chromium carbide coating, can effectively alleviate gas-liquid mixed gas pair
The erosion of protection against erosion arc panel extends the service life of protection against erosion arc panel；
（Three）The distance of the Heisui River inlet tube lower edge of the protection against erosion arc panel lower end and tank body is not less than the Heisui River of tank body
The half of inlet tube caliber can make the tube wall of steam and Heisui River inlet tube of the slag liquid blending agent far from tank body, be bonded erosion control
Brush arc panel moves, and prevents washing away to the tube wall of the Heisui River inlet tube of tank body, improves the service life of tank body, has good
Service life.
