Description
Technical field
The present invention relates to a kind of drainage arrangement, be specifically related to a kind of converter gas wet dedusting drainage arrangement.
Background technology
Converter gas wet dust collecting process can produce substantial amounts of dust-laden sewage, for preventing coal gas in sewage discharge process from passing through
Drainage pipeline leaks, it is necessary to arrange it can be avoided that the most identical drainage arrangement of dust collecting process drain pipe and ambient atmosphere.Typically
Way be bottom drainage arrangement, to remain certain water, dust collecting process drain pipe is inserted certain depth in water, is formed
Water seal, dedusting sewage is discharged by overflow.Bulky grain dirt mud in converter gas wet dedusting sewage can be bottom drainage arrangement
Deposition, needs to discharge in time bottom dirt mud after work a period of time, the dirt mud being otherwise gradually increased can by process drain pipe choking,
Sewage cannot be discharged from dust collecting process, causes security incident.
Due to more containing sand in converter gas wet dedusting sewage, the frequently operation of dirt dirt water bottom discharge,
Easily wear and tear blowoff valve valve plate sealing gasket containing husky sewage, after the blowoff valve that blow-off line is arranged uses a period of time, hold
Easily occur being not closed completely, leaking infiltration phenomenon；And once occur that blowoff valve is not closed completely, valve plate seeps water phenomenon,
Bottom dirt mud is assembled inside blowoff valve in a large number by valve plate infiltration filtering effect, until inside completely plugged blowoff valve
Sewage draining exit, causes simple top portion hydraulic pressure effect cannot discharge base sludge, needs to stop producing, is manually entered drainage arrangement clear
Reason mud, expends a large amount of manpower and materials, increases production cost.

By such scheme, described case body is arranged on bracing frame.
By such scheme, motor is driven to be arranged in frame.
The spiral conveyor rod the invention have the benefit that 1, being arranged on bottom serves bottom agitation during blowdown
Dirt mud, the effect of clear drains, even in the case of drainage pipeline is completely plugged, by the agitation of spiral conveyor rod,
Mud produces space in blow-off line, promotes sewage and mixes with mud, the final drive smooth and easy discharge of dirt mud；Prior
It is that spiral conveyor rod provides the power that mud is discharged, and is pushed the most forward by mud, accelerates the discharge of mud, fully keep away
Exempt from bowl sewage draining pipeline blockage, it is ensured that the stable operation of whole drainage arrangement；2, lower part box is installed in the bottom in water seal district,
During blowdown, upper box body can apply certain pressure to mud, can accelerate the discharge of mud；3, this equipment safety is reliable, daily dimension
Protecting simple, operating cost is low.

Detailed description of the invention
In order to be more fully understood that the present invention, with specific embodiment, the present invention is further described below in conjunction with the accompanying drawings.
A kind of converter gas wet dedusting drainage arrangement as shown in Fig. 1 ~ 3, mainly includes case body, spiral conveyor rod
12, driving motor 11 and automatic control system, described case body is arranged on bracing frame 14, and case body includes upper box body 2 He
Lower part box 3, the upper end of upper box body 2 is provided with top cover 1, and top cover 1 offers discharge duct 5 and inlet channel 4；Upper box body
2 is contraminated zone, and the lower end of described inlet channel 4 is stretched in upper box body 2, and the bottom of upper box body 2 is installed on drainage pipeline 7；
Lower part box 3 is mud district, and a side bottom of lower part box 3 is provided with blow-off line 9, and the porch of blow-off line 9 is installed on row
Dirty valve 10；Described spiral conveyor rod 12 is installed in the bottom of lower part box 3, and the length direction of spiral conveyor rod 12 is parallel to blowdown
The axis of pipeline 9, and to stretch into blow-off line 9 internal, under the other end of spiral conveyor rod 12 stretches out in one end of spiral conveyor rod 12
Portion's casing 3, is connected with the drive end driving motor 11；Motor 11 is driven to drive spiral conveyor rod 12 to rotate；Motor 11 is driven to pacify
It is contained in frame 13；Described blowoff valve 10 is electrodynamic valve or pneumatic operated valve, and blowoff valve 10, driving motor 11 with automatically controlling are respectively
System electrical connection.
Being installed on dividing plate 8 in upper box body 2, upper box body 2 is divided into water seal district 16 and overflow area 17, institute by dividing plate 8
Water seal district 16 is stretched in the lower end stating inlet channel 4, and water seal district 16 has certain water seal height for inlet channel 4, plays close
Envelope effect, prevents coal gas of converter from directly communicating (the coal gas of the internal remaining of drainage arrangement with ambient atmosphere environment by inlet channel 4
The safety zone specified is drained into) through exhaustor 5；Described drainage pipeline 7 is installed in overflow area 17.Upper box body in water seal district 16
2 sidewalls are provided with inspection hole 6 and water level detecting meter 15, and water level detecting meter 15 electrically connects with automatic control system；Automatically control and be
The lowest water level to water seal district 16 of uniting is provided with a setting value, and the height of described dividing plate 8 is not less than this setting value.Described lower tank
One sidewall of body 3 is in tilted layout to blow-off line 9, is installed in the bottom in upper box body 2 water seal district 16, connects with water seal district 16,
When blowdown, upper box body 2 can apply certain pressure to mud, accelerates the discharge of mud.
The foreign material such as dust-laden sewage enters the water seal district 16 of upper box body 2 through inlet channel 4, the solid particle in sewage are by water
Envelope district 16 is precipitated to mud district；Part supernatant warp when the liquid level in water seal district 16 exceedes the height of dividing plate 8, in water seal district 16
