The pressure regulating system 6 is made up of pressure compensator, first pressure compensating port 5 and second pressure compensating port 7, institute
Stating pressure regulating system 6 respectively has a pressure compensation mouthful above and below the packing plate on the tank inner wall of both sides, i.e. the positioned at upper water box
One pressure compensation mouthful 5 and the second pressure compensating port 7 positioned at lower header, pressure regulating system are insulated by pressure compensation mouthful balance
Air pressure in two water tanks above and below plate.
The control system is connected for data monitoring with pressure monitor system and water level monitoring system, the water level prison
Examining system and pressure monitor system are arranged on device water tank madial wall, and the water level monitoring system refers to be located at packing plate
Two water level monitors of both sides up and down, i.e., close to the He of the first water level monitor 17 of packing Board position on the wall of upper water box side
Close to the second water level monitor 12 of water tank bottom position, the first water level monitor 17 and the second water level on the wall of lower header side
Monitor 12 is both connected to control system 8；The value of two Level monitors is according to liquid pressure formulaP=ρghCalculate
Arrive, i.e., registration is expressed as h1、h2, work as h1＞ 0 and h2During ＞ 0, i.e., grain slag mixing liquid water level is in the first water level monitor 17
On, as shown in figure 3, the control of control system 8 packing plate 16 moves closure along packing plate guide groove 15；Work as h1＞ 0 and h2When=0, i.e.,
Grain slag mixing liquid water level is on the first water level monitor 17 and the second water level monitor 12 monitoring water level is zero, i.e. bottom water tank
Interior grain slag is drained.
The pressure monitor system refers to two pressure monitors for being located at packing plate both sides about 16, i.e., positioned at upper water box
Close to the of packing Board position close to the first pressure monitor 18 of tank top position and on the wall of lower header side on the wall of side
Two pressure monitors 14, first pressure monitor 18 and second pressure monitor 14 are both connected to control system 8, the control system
The air pressure of the upper lower header of 8 control pressure regulating systems 6 of uniting regulation；Led for monitoring the draining deslagging after the packing closure closing of plate 16
Lower header air pressure is different in cause, because the packing upper water box of plate 16 uses negative pressure mash gas extraction, i.e. pnFor extraction negative pressure value, and insulate
The lower header of plate 16 causes vacuum influence draining tapping process due to the draining deslagging of grain slag emptying pump 10, may lead to a certain extent
Packing plate 16 is caused to damage and when later stage packing plate 16 is opened because the excessive packing plate 16 of upper lower header pressure difference can not be opened；The
One pressure monitor 18, the Monitoring Data of second pressure monitor 14 are respectively p1、p2, when device does not start negative pressure extraction work,
p1=p2=p0, p0For atmospheric value；It is p when negative pressure extraction1=pn, pnFor gas pumping negative pressure value, i.e. p1≠p2, control system 8
The upper lower header air pressure of the regulation of control pressure regulating system 6, prevents lower header from being damaged due to air pressure inequality while facilitating the later stage to seal
Dividing plate 16 is opened.
The deslagging drainage system 9 is made up of grain slag emptying pump 10 and pump chamber, the bottom of the pump chamber and device water tank
Connect, and pump chamber is connected by opening up grain slag floss hole 11 with device main box bottom, the grain slag floss hole 11 extends to dress
Put outside main box, because slag body precipitation is gathered in water tank bottom in grain slag mixing liquid, easily pipe is blocked when discharging casing
Road, under packing plate closing state, as shown in figure 4, the slag body and water that stir water tank bottom deposition by grain slag agitator 13 are equal
Even mixing, then through grain slag floss hole 11 discharge casing by grain slag emptying pump 10.
Operation principle of the present utility model is as shown in fig. 7, the utility model is related to after drain slag-discharging unlatching, and pressure is supervised
Examining system, water level monitoring system and condenser system are opened and are operated, and packing plate is in open mode, now pressure monitor system
Monitor that upper water box and lower header pressure are equal, i.e. Monitoring Data p1=p2=p0, p0For atmospheric value, due to there is no water in water tank,
Water level monitoring system is monitored less than water level, i.e. Monitoring Data h1=h2=0；The mixtures such as gas, water, slag body are from gas pumping air inlet
Mouth 1 enters device water tank 21, and gas goes out in device main box 19, gas after condenser system 3 from gas negative pressure extraction mouthful 2
The mixture such as water, slag body by self gravitation effect fall into the vapor in device water tank, gas and pass through in condenser system 3 and erect
The spiral cooler 4 directly disposed condenses into water, enters device water tank 19 through self gravitation effect；With water, slag body in water tank
Deng the accumulation of mixture, the second water level monitor 12 that lower header is set can monitor data, then Monitoring Data h2≠ 0, with
The mixtures such as water, slag body are cumulative, and water level is begun to ramp up, when water level exceedes the first water level monitor 17 set to upper water box
When, then Monitoring Data h1＞ 0, now control system 8 h can be met according to Monitoring Data1＞ 0 and h2≠ 0 condition, so as to control
Packing plate 16 moves closure along packing plate guide groove 15, as shown in fig. 6, control system control simultaneously starts the He of grain slag agitator 13
Grain slag emptying pump 10, carries out drainage, slag discharge；Now because the closure of packing plate, causes the pressure change of upper water box and lower header,
First pressure monitor 18 and the Monitoring Data of second pressure monitor 14 are respectively p1、p2, upper water box carries out negative pressure extraction, then p1=
pn, pnFor extraction negative pressure pressure, therefore p1≠p2, the upper lower header air pressure of the now control pressure regulating system 6 of control system 8 regulation,
Prevent lower header from being opened because air pressure inequality is damaged while facilitating the later stage to insulate plate 16；After the completion of drainage, slag discharge, in lower header
Water level is reduced to close to bottom, the Monitoring Data h of the second level sensor 122=0, and because packing plate has when closing in upper water box
Ponding, therefore the Monitoring Data h of the first level sensor 171＞ 0, now control system 8 h can be met according to Monitoring Data1＞ 0 and
h2=0 condition, control packing plate 16 is again turned on, as shown in figure 5, grain slag agitator 13 and grain slag emptying pump 10 stop simultaneously
Work；The process of the mixtures such as water, slag body accumulation is gone successively to, when meeting h1＞ 0 and h2During ≠ 0 condition, control system control
Packing plate 16 moves closure along packing plate guide groove 15, carries out drainage, slag discharge, so continuously repeatedly so that gas pumping is with discharging water
Tapping process is independent of each other, and each autonomous working is run and extraction process interruption is discontinuous.When completing gas pumping by gas
Extraction import is directly connected to clear water pipe, being capable of automatic flushing device inner bin and equipment, whole-course automation, without manual operation
Interference, continuous uninterrupted, Effec-tive Function.
The protection domain of this utility model is not limited to the content on specification, every identical with above-mentioned implementation structure, or
The technology deformation that person is made according to the utility model technical principle, belongs to the protection domain of the utility model requirement.
