The separation of solid and liquid of the industries such as chemical industry, chemical and medicine industry, coal mine separation, technics of metallurgy mineral dressing, Aluminum, sewage disposal.
Two, background technology：
The rotating machinery for being related to being separated by solid-liquid separation has very much, industrially has rotary vaccum filter using more at present
Group, belt vacuum filter group, centrifugal separator, various filter-presses etc., but these widely applied mechanical equipments, respectively
There is following defects：
1. vacuum filter unit is complicated huge, power consumption is big.
It is single to cover such as 200,000 tons/year of methanol device coal water slurry gasification ash water process major event vacuum band-type filter machine group
The Typical Disposition of unit is in addition to driving power is the vacuum filter of 5.5KW, it is necessary to which configuration driven power is the pendular ring of 55KW
The butt mortar production capacity of formula vacuum pump group, this single set vacuum band-type filter machine group only has 61.53kg/ (M2H), energy consumption ratio is but
Up to 0.0605KWh/kg.
2. filter cake water capacity after centrifugal separator low yield, separation is big, power consumption is big.
It is the decanting centrifuge applied in 150,000 tons/year of ethylene process PVC devices such as scale, separate unit centrifuge
Maximum PVC butts production capacity only has 15000kg/h, and the PVC filter cake water capacities after separation are up to 22~25%, single machine driving power
Up to 250KW, energy consumption ratio is 0.0133KWh/kg.
For another example scale is the domestic decanting centrifuge applied in 400,000 tons/year of calcium carbide process PVC device, separate unit from
The maximum PVC butts production capacity of scheming only has 7500kg/h, the PVC filter cakes water capacity after separation up to 22~25%, single machine drives work(
Rate reaches 132KW, and energy consumption ratio is 0.01408KWh/kg.
3. rotary drum filter-press gas consumption is big in, filter cake cannot be expelled directly out from filter cake outlet, it is necessary to be arranged in filter cake
Exit adds discharging sealing device, and filter cake could intermittently or serially be discharged.
Such as the rotary drum filter-press for continuously detaching PTA slurries that BIRD YOUNG companies develop, turn because filtering
Drum is internal and gas-liquid two-phase discharge pipe is all-pass, and in operation, some is immersed in filter pocket rotary drum, and other parts are because of place
The channel in these gas flows external world is formed in pressure filtration gas, this makes pressure filtration gas consumption at tens of multiplications
Add.It is 11052kg/ (M with butt production capacity2H) for rotary drum filter-press, the processes such as gas phase pressure filtration are consumed
Gas gross is up to 38760NM3/ h, gas consumption ratio may be up to 0.7751NM3/kg.And rotation must be added in filter cake outlet
Valve just can make filter cake be delivered continuously to next drying process.
4. rotating disc type filter-press productivity per unit is low, gas consumption is big and must add discharge sealing at outlet
Device, control filter cake interval discharge or continuous discharge.
The GPJ-120 rotating disc type continuous pressure filters that raw coal fine purifiation or tail coal recycle such as are used for, because of the filtering of its turntable
Section is vertical direction, and filter cake is suspended on turntable under differential pressure action, and filter cake is too thick easy to fall off；Although gas-liquid two-phase is logical
Road is subregion, but is immersed in filter pocket because each turntable only has fraction filtering surface, and most of filtering surface, which is but in, to pressurize
In air filtration body, these filtering surfaces constitute the shortcut channel outside pressure filtration gas discharge filter, make pressure filtration gas
Consumption be multiplied so that gas consumption is big, gas consumption ratio greatly reach 0.08NM3/ kg, the low yield of unit area, butt production capacity are only
333.3kg/(M2·h)。
5. the filter-press standalone architecture of the external independent filter pocket formula filter element of rotary drum is complicated in, both ends shaft seal structure
Bulky dimensions, sealing size are 1600mm, are easily leaked, and the packing seal service life is extremely short, and longest also only there are three the moon, is safeguarded and protected
Support frequently, cost it is high.
Such as the pressure for the external independent filter pocket formula filter element of interior rotary drum for detaching PTA slurries that German BHS companies develop
Power filter, sealing easily leak, and generally often run and begin within 8 hours leak therefore need to maintain airtight and watertight padding for every eight hours
Once, the sealing service life is generally 1~2 month, and longest service life also only has March.Need to change within average 2 months a batch from Germany into
The expensive filler of mouth, maintenance cost are high.
Chinese patent CN85105930A describes a kind of continuous pressure filter, it is a kind of outer drum formula pressure filtration
Machine, the interior setting sieve plate of rotary drum and filter cloth constitute filter element, using the positive pressure operation principle of plate and frame type filter-press, using rotary drum
The flows such as the subregion filtering of vacuum filter, drying, blowback discharging pass through and convey raw coal or tail coal suspension into cylinder, compression
Air makes filtrate pass through filter cloth, sieve plate, through conduit, dispensing head discharge, and the cleaned coal filter cake of fine particle is attached to sieve plate filter cloth
Surface on.Its sieve plate is evenly distributed along cylinder inner wall, respectively independent, and every piece of sieve plate is corresponded with cylinder outer catheter, each piece
When sieve plate rotates to upper end, conduit is connected with dispensing head blowback air, and the filter cake being attached on sieve plate filter cloth is blown off by blowback air, falls
It falls in the receiving hopper vertically stood in cylinder, send to discharging hermatic door and be discharged through spiral conveyer, but its presence is following apparent
Disadvantage：(1), it because its filter element is the filter cloth being arranged on sieve plate, therefore is formed by filter cake thickness and is restricted, cellar area
On intensity filter is low, low yield；(2), it is pressurized the chief motivation as filtering using gas phase, comes from the liquid phase pressure of material
Power is not utilized and is wasted, therefore its gas consumption is big, and energy consumption is big；(3), discharge zone and gas phase pressurizing filter area are laid in identical
It in the pressure chamber of pressure rating, is unloaded to smoothly blow filter cake, it is necessary to make the pressure of blowback air at least than filtering supercharging gas
The big 0.5kg/cm of body pressure2, this not only needs the work air source of two kinds of pressure ratings, but also after leading to gas phase pressurizing filter
Pressed gas cannot directly be recycled for discharging, caused the energy to waste, increased units consumption；(4), after feeding screw
The inhomogeneities for the filter cake that the intermittent take-off Men Yin of used cylinder piston control is sent can lead to pressure filtration gas outward
Leakage, therefore its gas consumption amount is big；(5), without flusher in filtration barrel body, the chemical industry dress for having rinsing requirement to filter cake cannot be applicable in
It sets, decontamination processing cannot be carried out to filter cake.
