Description
Technical field
The utility model relates to a kind of gas filtration deduster single-purpose filtering element deashing device.
Background technology
In mineral heating furnace flue dust pelletizing system running, the high-temperature flue gas that mine heat furnace smelting produces is under blower fan suction, be introduced into gas filtration deduster and carry out gas solid separation, clean gas after gas solid separation enters blower fan subsequently, and under the mechanical energy effect of blower fan, escape and enter follow-up recovery system from blower fan exhaust outlet.Wherein, in the time that high-temperature gas enters gas filtration deduster inner barrel, will directly contact and carry out gas solid separation with filter core, the negative pressure producing by blower fan makes a large amount of flue gases pass filter core, under solid particulate matter being stopped, makes clean gas enter recovery system simultaneously.And in use there is the phenomenon that produces filter cake in filter core, filter area is reduced, air flux reduces, and yield reduces, and can have a significant impact the production of closed mineral hot furnace.Gas filtration deduster employing is at present carried out reverse gas cleaning to back-blowing device to filter core and can not be removed filter cake completely, therefore need to be to the flue gas dust collecting system processing of stopping after operation a period of time, directly enter the manual filter cake that strikes off cartridge surface in gas filtration deduster cylindrical shell from gas filtration deduster downside manhole by workman, have certain potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide after a kind of system shutdown the gas filtration deduster single-purpose filtering element deashing device that enters gas filtration deduster inner barrel and can carry out filter core efficient deashing without workman.
This filter core deashing device comprises the long holding rod of ventilation, the front end of the long holding rod of ventilation is provided with jet thrust, the rear end of the long holding rod of ventilation is connected with air supply hose, jet thrust, ventilation holding rod and air supply hose three are communicated with, the holding part of the long holding rod of ventilation is positioned at the rear end of the long holding rod of this ventilation, on jet thrust, be provided with top spout, while thering is the holding part of holding the long holding rod of ventilation after operator sends this filter core deashing device into gas filtration deduster cylindrical shell from gas filtration deduster downside manhole at described manhole place between the center line of the center line of top spout and the long holding rod of ventilation, make this top spout just to the angle below element kit.
The using method of above-mentioned filter core deashing device is: after system shutdown, open gas filtration deduster downside manhole, then filter core deashing device is sent in gas filtration deduster cylindrical shell, last operation person makes this top spout just to below element kit when (operator is without enter gas filtration deduster cylindrical shell from manhole) holds the holding part of the long holding rod of ventilation at this manhole place, the high pressure deashing gas transmitting through air supply hose enters jet thrust by the long holding rod of ventilating, then spray from top spout, deashing gas is with the direction impact filter cake tangent with cartridge surface, play efficient ash-removal effect.
To partly provide in the following description the utility model is described further, the utility model is additional aspect and advantage below in conjunction with the drawings and specific embodiments, part will become obviously from the following description, or recognize by practice of the present utility model.

Fig. 2 is the structural representation at the utility model gas filtration deduster single-purpose filtering element deashing device jet thrust position.
Fig. 3 is the another kind of structural representation at the utility model gas filtration deduster single-purpose filtering element deashing device jet thrust position.
Detailed description of the invention
As shown in Figure 1, gas filtration deduster 200 comprises gas filtration deduster cylindrical shell, in cylindrical shell, by orifice plate 240, element kit 210 is installed, and the top of element kit 210 is provided with back-blowing device 230, and gas filtration deduster cylindrical shell downside is provided with manhole 220.When the 200 normal work of gas filtration deduster, first gas to be filtered enter the cavity that is arranged in orifice plate 240 bottoms in gas filtration deduster cylindrical shell, then filter by element kit 210, clean gas after filtration enters the cavity that is arranged in orifice plate 240 tops in gas filtration deduster cylindrical shell, discharges subsequently from gas filtration deduster 200; In the time that cartridge surface is adhered to certain filter cake, start back-blowing device 230, by blowback air, element kit 210 is carried out to reverse gas cleaning, after reverse gas cleaning, continue above-mentioned filtration.Above-mentioned gas filter collector 200 moved after a period of time, and then system shutdown opens manhole 220, and a filter core deashing device 100 is sent into manhole 220.
As shown in Figure 1, 2, this filter core deashing device 100 comprises the long holding rod 120 of a ventilation, the front end of long holding rod 120 of ventilating is provided with jet thrust 110, rear end is connected with air supply hose 130, jet thrust 110, ventilation holding rod 120 and air supply hose 130 threes are communicated with, the holding part of long holding rod 120 of ventilating is positioned at the rear end of the long holding rod 120 of this ventilation, is provided with top spout 112 on jet thrust 110, and the center line 111 of top spout 112 is 110-130 ° with the angle of the center line 121 of the long holding rod 120 of ventilation.Above-mentioned filter core deashing device 100 is sent in gas filtration deduster cylindrical shell, last operation person at manhole 220 places (operator is without enter gas filtration deduster cylindrical shell from manhole) hold ventilation long holding rod 120 holding part time make this top spout 112 just to element kit 210 belows, the high pressure deashing gas (preferred nitrogen) transmitting through air supply hose enters jet thrust 110 by the long holding rod 120 of ventilating, then spray from top spout 112, deashing gas, with the direction impact filter cake tangent with cartridge surface, plays efficient ash-removal effect.
