Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, low-temperature boiling chlorination furnace continuous deslagging device disclosed by the invention, comprises walkthrough slag ladle 2, residual cake valve 3, chlorination furnace residue outlet 5, walkthrough slag ladle residue outlet 6 and scum pipe 7; Described chlorination furnace residue outlet 5 two ends are respectively side a and b, and described A end is connected with boiling chloridizing furnace 1, and described B end is connected with walkthrough slag ladle 2, and A end is held higher than B; Described walkthrough slag ladle residue outlet 6 two ends are respectively C end and D end, and described C end is connected with walkthrough slag ladle 2, and described D end is connected with residual cake valve 3, and C end is held higher than D; Be provided with washing gas entrance 21 bottom described walkthrough slag ladle 2, described walkthrough slag ladle 2 top is provided with waste gas escape pipe 22, is provided with deslagging gas inlet pipe bottom described residual cake valve 3, and described scum pipe 7 is connected with residual cake valve 3.
For the benefit of expect that slag is in the conveying to material slag of chlorination furnace residue outlet 5 and walkthrough slag ladle residue outlet 6, chlorination furnace residue outlet 5A holds higher than B end, is preferably 10 ° ~ 80 °, equally with the angle of horizontal plane, the C end of walkthrough slag ladle residue outlet 6 is held higher than D, same with the angle of horizontal plane preferably 10 ° ~ 80 °.After boiling chloridizing furnace 1 normally starts, washing gas is passed into walkthrough slag ladle 2 by the washing gas entrance 21 bottom walkthrough slag ladle 2, and in residual cake valve 3, pass into deslagging gas by the deslagging gas inlet pipe arranged bottom residual cake valve 3, washing gas is preferably nitrogen, certainly also can adopt if the gases such as pressurized air are as washing gas, and deslagging gas adopts pressurized air usually.Along with chlorination furnace runs continuously, material slag in chlorination furnace enters walkthrough slag ladle 2 by chlorination furnace residue outlet 5, when charge level height in walkthrough slag ladle 2 arrives after C end height, material slag enters residual cake valve 3 by walkthrough slag ladle residue outlet 6, and after residual cake valve 3 is full of material slag, scum pipe 7 starts outside deslagging, during chlorination furnace blowing out, scum pipe 7 is slagged tap and is stopped thereupon, and stop washing gas air feed and deslagging gas air feed, boiling chloridizing furnace 1 continuous deslagging device quits work.Washing gas entrance 22 is connected with flare system, containing Cl
2, TiCl
4, the gas such as HCl waste gas; under the effect of washing gas; enter flare system from washing gas entrance 22 to be focused on; thus available protecting atmospheric environment; boiling chloridizing furnace 1 bed height kept stable in production process; fluidized state is stablized, and is of value to low temperature chlorination stove continuous and steady operation.
For ease of centralized collection material slag, as optimal way, this low-temperature boiling chlorination furnace continuous deslagging device is provided with dreg-accepting hopper 4, and described residual cake valve 3 is connected with dreg-accepting hopper 4 by scum pipe 7.Described scum pipe 7 is connected to residual cake valve 3 top, and described scum pipe 7 is bend pipe, and the middle part of bend pipe is higher than bend pipe two ends.Residual cake valve 3 arranges deslagging gas inlet pipe, and top arranges scum pipe 7, and scum pipe 7 adopts bend pipe to arrange, and the size be conducive to by controlling deslagging gas controls the speed of deslagging, and material slag can be imported in dreg-accepting hopper 4 smoothly while formation material envelope.And the angle of bend of bend pipe is preferably 90 ° ~ 120 °, the elbow of 90 ° or 120 ° and straight pipeline usually can be adopted to splice and to carry out bend pipe.
For the highest point making material slag can be smoothly through bend pipe after entering residual cake valve 3 enters dreg-accepting hopper 4, described scum pipe 7 highest point midway is E point, and described C end is higher than E point.C end higher than D end can make material slag enter smoothly residual cake valve 3, C end then make the material slag height in the walkthrough slag ladle residue outlet 6 before residual cake valve 3 higher than the material slag height of the scum pipe 7 after residual cake valve 3 higher than E point, thus be conducive to expect slag discharged by scum pipe 7.And, as optimal way, described C end is higher than A end, make walkthrough slag ladle 2 at interior material slag height higher than side a and b, when stablizing deslagging, in chlorination furnace residue outlet 5, be full of material slag, ensure that the chlorine in chlorination furnace not easily leaks on the one hand, can effectively prevent washing gas from entering chlorination furnace on the other hand, affect the normal operation of chlorination furnace.
In residual cake valve 3, deslagging gas will bear the effect of two aspects, the fluidisation keeping material slag on the one hand, and make material slag from the slag input end motion of residual cake valve 3 to slag output end, be exactly impel material slag to enter scum pipe 7 to discharge on the other hand, and independent one deslagging gas actual be the effect that cannot realize above-mentioned two aspects satisfactorily, therefore, as optimal way, described deslagging gas inlet pipe comprises No. 1 inlet pipe 31 and No. 2 inlet pipe 32, middle part in described residual cake valve 3 is provided with dividing plate 33, described dividing plate 33 is highly 1/2 ~ 2/3 times of residual cake valve 3 cavity heights, described No. 1 inlet pipe 31 and No. 2 inlet pipe 32 are arranged at dividing plate 33 both sides respectively, described walkthrough slag ladle 2 residue outlet and No. 1 inlet pipe 31 are positioned at dividing plate 33 homonymy, described scum pipe 7 and No. 2 inlet pipe 32 are positioned at dividing plate 33 homonymy.And for ease of regulating and controlling the air input of No. 1 inlet pipe 31 and No. 2 inlet pipe 32, described No. 1 inlet pipe 31 and No. 2 inlet pipe 32 are provided with air intake control valve.The Main Function of No. 1 inlet pipe 31 air inlet makes it be in fluidized state at once after material slag enters residual cake valve 3, and promote that material slag crosses dividing plate 33 to the flowing of scum pipe 7 direction, and the Main Function of No. 2 inlet pipe 32 impels material slag to be discharged by scum pipe 7.No. 1 inlet pipe 31 and No. 2 inlet pipe 32 regulate and control respectively by air intake control valve, be easy to realize automatic control, No. 1 inlet pipe 31 air inlet requires under ensureing that material slag comparatively successfully can cross the prerequisite that dividing plate 33 flows to scum pipe 7 direction, reduce the impact for the charging of walkthrough slag ladle residue outlet 6, the air inlet situation of No. 2 inlet pipe 32 then directly can have influence on the speed of the deslagging of residual cake valve 3 as far as possible.Dividing plate 33 1 aspect can isolate No. 1 inlet pipe 31 and the air inlet of No. 2 inlet pipe 32, avoids both to influence each other, and on the other hand when deslagging gas inlet pipe stops air inlet, can stop rapidly that the flowing of material slag is slagged tap.
