Description of drawings
Fig. 1 is the structural representation that high temperature gas cleaning reclaims the closed ash-discharging device;
Fig. 2 is the structural representation of bimetallic rotary valve.
The specific embodiment
As shown in Figure 1, high temperature gas cleaning provided by the utility model reclaims the closed ash-discharging device, it is ash bucket 1 below that is connected the high-temperature gas retracting device, comprise bimetallic rotary valve 2, ash unloading bin 3, star-shaped ash unloading valve 4, ash-unloading tube 5 and controller 6, described bimetallic rotary valve 2 is connected described ash bucket 1 lower opening place, described ash unloading bin 3 upper ends are connected with described bimetallic rotary valve 2, described ash unloading bin 3 lower ends are connected with described star-shaped ash unloading valve 4, described star-shaped ash unloading valve 4 lower ends link to each other with described ash-unloading tube 5, described controller 6 links to each other with described bimetallic rotary valve 2 and described star-shaped ash unloading valve 4 simultaneously, and carry out interlocked control, promptly, control is wherein any valve opening the time, control another one valve closing.
See also shown in Figure 2, it is the structural representation of bimetallic rotary valve 2 provided by the utility model, comprise the rotary valve plate 21 of metal material and the fixedly valve plate 22 of metal material, fixedly offer valve port 221 on the valve plate 22, described rotary valve plate 21 is fitted in fixedly valve plate 22 belows, and link to each other with the end of a pivoted arm 23, the head end of described pivoted arm 23 is fixedlyed connected with a rotating shaft 24, described rotating shaft 24 is perpendicular to fixedly valve plate 22 settings, drive described pivoted arm 23 rotations, to control described rotary valve plate 21 with described valve port 221 airtight or unlatchings.
Wherein, in order to reach better sealing effectiveness:
(1) in described rotating shaft 24, also be provided with a preloading spring 25, and described preloading spring 25 and described pivoted arm 23 butts, thereby by described pivoted arm 23 is upwards pushed, described rotary valve plate 21 is connected airtight with described fixedly valve plate 22.
(2) described rotary valve plate 21 and fixedly valve plate 22, again through sticking mill, to guarantee the driving fit zero-clearance, during two plate relative motions, any grit therebetween can both be removed after grinding.
(3) on the valve port 221 of fixing valve plate 22, be embedded a circle carbide ring 26, can increase anti-wear performance, further guarantee sealing effectiveness.
Adopt said structure, in case the ash discharge amount in the ash bucket 1 runs up to a certain degree, just close described star-shaped ash unloading valve 4 by described controller 6, in order to avoid air enters in the ash bucket 1, controller 6 (perhaps after a while) control bimetallic rotary valve 2 is simultaneously opened, and allows ash bucket 1 interior dust stratification fall into described ash unloading bin 3; Then, the described bimetallic unloading valve of controller 6 orders is closed, and (perhaps after a while) order bimetallic rotary valve 2 is opened simultaneously, the dust stratification in the ash unloading bin 3 can be discharged in the ash-unloading tube 5.
And the valve of described bimetallic rotary valve 2 and valve body all adopt the metal manufacturing, just can adapt to the high temperature of high-temperature gas, can seal below 400 ℃, and air pressure reaches the following high-temperature gas of 1MPa; Because valve and valve body employing rotary-cut driving fit even have dust stratification between valve and valve body, also can be removed dust stratification by the rotary-cut of valve plate, make the tight involution of valve plate and valve body again, it is unreal and cause gas permeation can not produce valve closing.
As seen, the utility model is by interlocked control, can effectively control air and enter amount in the ash bucket 1, thereby avoid the generation of exploding, to such an extent as to and effectively avoided valve seal the situation of tight gas leakage occur, improved job security, guaranteed the security of the lives and property.
Control the mode of bimetallic rotary valve 2 and star-shaped ash unloading valve 4 as for controller 6, can adopt the mechanical type control mode, for example, adopt sprocket wheel interlocked control structure, cam interlocked control structure, connecting rod interlocked control structure or gear type interlocked control structure, can also adopt electronic control mode, for example, controller 6 is electrically connected with the control circuit of the dynamic structure (as: motor) of bimetallic rotary valve 2 and star-shaped ash unloading valve 4 respectively, these control modes all are easier to realize, will not have given unnecessary details in this application.
What need to replenish is, the size of described ash unloading bin 3 can and be unloaded grey frequency and determine according to the ash discharge amount, if the ash discharge amount is big or to unload grey frequency low, just needs to strengthen the volume of ash unloading bin 3; If the ash discharge amount is little or unload grey frequency height, just can correspondingly dwindle the volume of ash unloading bin 3.
In addition, between described ash bucket 1, bimetallic rotary valve 2, ash unloading bin 3, star-shaped ash unloading valve 4 and the ash-unloading tube 5, preferably adopt flange to connect, not only structure is firm, sealing is reliable, and with low cost, convenient disassembly.
At last, it is as follows to sum up advantage of the present utility model:
1. the utility model is to guarantee in the high temperature coal gas purification process, reliable and secure the drawing off of ash bucket 1 dust stratification, and it is mixed in unloading grey process air and coal gas to be oozed, and has an accident.
2. the high-temperature metal rotary valve is in normally off, when ash bucket 1 need unload ash, the metal rotary valve is opened, the tail ash is discharged into ash unloading bin 3 through valve, through certain hour, the metal rotary valve cuts out, and computer control star is unloaded opening of valves, and the tail ash in the ash unloading bin 3 promptly flows out by ash pipe by star valve and enters the grey storehouse of storage.Whole unloading do not have flowing of air in the grey process, two valves, and one opens one closes, and one closes one opens the implementation interlocking.The isolation of high temperature CO gas and air is guaranteed in the heatproof of high-temperature metal unloading valve, wear-resisting, anti-blocking design, and this is a reliable and secure novel ash-discharging device.
More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
