Description
Technical field
The invention belongs to filtration and separation techniques fields, and in particular to a kind of helixseal for supercritical water treatment technique
Continuous pulp discharge filter.
Background technology
At present continuous filter in Chemical Manufacture using very extensive, have simple in structure, filtering accuracy is high, can from
Many advantages, such as dynamic cleaning strainer and PLC intelligent control discharges.Since solenoid valve is quick on the draw, safe to use, price is relatively low,
So the discharge device of conventional continuous filter is all that solenoid valve is used to be switched as drainage line, and solenoid valve is being arranged vertically
Reliability in expects pipe is very poor, and service life is significantly limited, therefore the drainage conduit of conventional continuous filter is all horizontally mounted.Even
Continuing the normal discharging process of filter is：Entered inside filter screen by inlet by filtrate, with from inside to outside by filter screen, after filter
Clear liquid subsequent technique is entered by purified liquor outlet, filter residue works as strainer since the interception function of filter screen is accumulated in strainer inner wall
When inner wall runs up to a certain amount of filter residue, monitoring system monitoring to pressure difference reaches cleaning pressure difference or is sentenced according to user's setting time
Disconnected scavenging period has arrived, then PLC sends out the electronic wiper of instruction startup, and electronic wiper starts to rotate, and cleans strainer inner wall filter residue, filter
Slag runs up to discharge solenoid valve import since gravitational settling acts on, meanwhile, PLC sends out instruction to solenoid valve, opens solenoid valve, profit
Discharge is carried out with the pressure in filter and the pressure difference of electromagnetic valve outlet.But for supercritical water treatment technique waste liquid or
Sludge is generally higher containing doses, still higher containing doses after processing, if strainer inner wall can in a short time accumulate very at this time
More filter residues, the filter residue washed down by electronic wiper can more cause in drainage conduit with the accumulation of discharge solenoid valve input end, formation
Close filter cake layer may reunite blocking, even if at this time opening discharge electromagnetic valve switch, by the pressure difference inside and outside filter also very
Hardly possible realizes smooth discharge, and the filter residue in filter then can be cumulative, influences the normal operation of filter, necessary at this time
It carries out manually dredging drainage line, secondary discharge, this method is time-consuming and laborious, extremely inefficient.In addition, i.e. enabled smoothly row
Material, this intermittent marker method for automatically controlling discharge by pressure difference or time have the shortcomings that a maximum：Filter during discharge
Inside cavity has pressure oscillation, and then influences filter inlet pipeline pressure, causes the pressure oscillation of whole system.Because row
The cavity of filter is by drainage conduit, discharge solenoid valve and atmosphere during material, with the progress of discharging process, the chamber of filter
Body pressure can be gradually reduced, and when discharging process terminates, discharge solenoid valve is closed, and the chamber pressure of filter can be gradually increasing again,
Blow-off valve constantly opens and closes like this, and pressure cannot keep stable always, will necessarily influence system safety.
Invention content
In order to overcome the problems of the above-mentioned prior art, the purpose of the present invention is to provide one kind at supercritical water
The helixseal continuous pulp discharge filter of science and engineering skill, the filtration device structure reasonable design is easy to operate, can realize continuously without blocking
Discharge, and filter cavity internal pressure is stablized during discharge.
The present invention is to be achieved through the following technical solutions：
A kind of helixseal continuous pulp discharge filter for supercritical water treatment technique, including filter cavity and setting
Motor at the top of filter cavity is equipped with feed inlet in filter chamber body wall upper end, was equipped in filter inside cavity
Strainer, filter screen outside are equipped with purified liquor outlet, and vertical drainage conduit is equipped in filter cavity bottom；Filter cavity central axes position
The drive rod that rotation is driven by motor is installed, drive rod is equipped with several electronic wipers, two are additionally provided in drive rod bottom
Grade helical blade.
The two-stage screw blade includes for stirring the stirring blade of filter residue and for sealing and pushing away successively from top to bottom
The helical blade of dynamic filter residue.
Stirring blade for stirring filter residue is arranged in the conical cavity of filter cavity bottom；For sealing and pushing filter
The helical blade of slag is arranged in vertical drainage conduit.
It is 0.15~1mm for sealing and pushing distance of the helical blade of filter residue apart from vertical discharge inside pipe wall.
For stir the diameter of the stirring blade of filter residue be more than for seal and push filter residue helical blade diameter.
It it is 2~8 for stirring the quantity of the stirring blade of filter residue.
It it is 2~10 for sealing and pushing the quantity of the helical blade of filter residue.
Discharge gate is welded in vertical discharge bottom of the tube.
Compared with prior art, the present invention has technique effect beneficial below：
The invention discloses a kind of helixseal continuous pulp discharge filter for supercritical water treatment technique, in filter chamber
Bottom arrange the vertical drainage conduit of vertical direction so that the filter residue in drainage conduit is than the filter residue in horizontally disposed drainage conduit
Because the reason of gravity and pressure is more prone to discharge, the continuous filter discharge for efficiently solving the high body containing feed liquid of filtering is easily stifled
The problem of plug.Meanwhile two-stage screw blade is additionally provided in drive rod bottom, it is to stir and seal, push filter cake layer, two-stage
Helical blade plays the role of corresponding in the different location that discharge falls, and ensures that material can be stablized while effectively discharge
Filter chamber internal pressure.The helixseal continuous pulp discharge filter that the present invention designs eliminates the setting of discharge solenoid valve, can
Ensure more smoothly discharge, and pressure stability, system safety.Therefore, helixseal continuous pulp discharge filter of the invention can
It is widely used in the waste liquid or Treatment of Sludge of supercritical water treatment technique.
Further, two-stage screw blade includes for stirring the stirring blade of filter residue and for sealing successively from top to bottom
And the helical blade of filter residue is pushed, the stirring blade for stirring filter residue is to build up extruding due to filter cake layer in order to prevent
It is caused reunite it is blocking and the problem of be difficult to move down, it is in order to by filter residue to play sealing and push the helical blade of filter residue
Pressure stability and promotion filter residue discharge when being sealed to realize discharging process in filter chamber body.
