Description
Technical field
The invention belongs to gas chamber design field, and in particular to a kind of gas chamber emergency diffusion device.
Background technology
Gas chamber is widely used in the recovery storage of iron and steel enterprise's by-product gas, mainly by cabinet side plate, cabinet top, piston, work
The part such as seben, bottom of cabinet plate, cabinet basis forms.Its cardinal principle is the up and down motion by piston, to realize going out for coal gas
Enter.
General gas chamber is designed with emergency diffusion device, and emergency diffusion device prevents that piston from transfiniting the accident of rushing to summit
One of preventive measure, in fact, the probability for gas chamber emergency diffusion occur is very small, but pacify as gas chamber
The last line of defense of row for the national games, is necessary again.
Existing gas chamber emergency diffusion device is broadly divided into two classes.
One kind is the emergency diffusion device of rubber film sealed dry type gas chamber, as shown in figure 1, mainly include diffusion valve 10,
Steel cable 9, steel cable tracting mechanism 8, piston automatic lifting mechanism 4, push rod 5 and manual opening mechanism 7.When piston runs to highest order
When, positioned at piston tip piston automatic lifting mechanism 4 will automatic lifting be located at the push rod 5 of the lower section of cabinet top plate 6, push rod
5 rising has driven steel cable 9 to move, and so as to improve the bonnet for the diffusion valve 10 for being located at the end of steel cable 9, now coal gas just can
Diffuse out from diffusion valve 10.Conversely, when piston position declines, piston automatic lifting mechanism 4 will depart from push rod 5, now put
Dissipating the bonnet of valve 10 can be playbacked under self gravitation effect so that diffusion valve 10 is closed, and is diffused and is no longer carried out.Meanwhile diffuse and be
Steel cable 9 in system be also connected with the manual opening mechanism 7 positioned at ground, it is necessary to when can manually opener 7 on ground
Diffusion valve 10 is opened, is diffused.Problems be present in such device：1) high velocity air can be to diffusion valve when diffusion valve 10 diffuses
10 form strong impact, sometimes result in valve body and more serious vibration and noise occur；2) device will to the accuracy of installation
Ask high, the phenomenon of " getting stuck " is likely to occur in otherwise running；3) grade of diffusion valve 10 key equipment is to be chronically exposed to big compression ring
It is perishable, easy to wear under border；4) sealing effectiveness at the bonnet of diffusion valve 10 is not fully up to expectations, and occur gas leak can
Can, certain potential safety hazard be present；5) device is complicated, and cost is high.
Another kind of is the emergency diffusion device of thin oil seal cabinet, as shown in Fig. 2 cabinet side plate 1 is provided with perforate 14, cabinet side plate
Perforate 14 on 1 connects with the bottom inlet of exhaust stack 2, is provided between cabinet side plate 1, piston ring beam 12 and piston sealing mechanism 11
Seal Oil 13；When piston runs to highest order, piston sealing mechanism 11 has just crossed the perforate 14 of cabinet side plate 1, now
Gas sprays from the perforate 14 of cabinet side plate 1 under the influence of air pressure with part Seal Oil 13 in cabinet, by exhaust stack 2, finally
Into air, realize the function of diffusing, then with cabinet gas diffuse, piston position will decline, piston sealing mechanism
11 fall back to the perforate of cabinet side plate 1 below 14, diffuse stopping, while part Seal Oil 13 is gradually back to the effect of gravity
At piston oil ditch.Problems be present in such device：1) a certain amount of Seal Oil 13 will necessarily be leaked out during emergency diffusion first,
And it is difficult to reclaim, economic loss is both present, and have pollution to site environment；2) system can not carry out manually opened promptly putting
Dissipate, certain hidden danger be present；3) exhaust stack 2 is chronically exposed under atmospheric environment, perishable, and its corrosion product is deposited in cabinet side
At the perforate 14 of plate 1, easily block and diffuse passage；4) need to carry out perforate to cabinet side plate 1, the structural behaviour of cabinet side plate 1 is deposited
Adversely affecting.
The content of the invention
It is an object of the invention to provide a kind of gas chamber emergency diffusion device, the apparatus structure is simple, and cost is low, operation peace
Entirely, diffusion valve is located inside gas chamber, and service life is long, it is good to inhale effect of making an uproar.
In order to solve above-mentioned technical problem, the technical scheme is that：
A kind of gas chamber emergency diffusion device, including steel cable, diffusion valve, the first exhaust stack and safe exhaust stack, diffusion valve
It is made up of valve seat and bonnet, valve seat is the container that top is provided with opening, and bonnet can cover the open top of valve seat simultaneously completely
Sealing, valve seat are fixed on bottom of cabinet plate, and the both ends of steel cable are connected with piston plate and bonnet respectively, and the effective length of steel cable, which is equal to, lives
The stroke of plug, one end of the first exhaust stack connects with valve seat, the other end passes gas chamber and connected with safe exhaust stack.
Further, it is respectively fixed with the magnet to attract each other on bonnet and valve seat.
Further, the contact position of valve seat and bonnet is provided with sealing ring, and sealing ring is fixed on valve seat, and bonnet is by hard material
Material is made.
Further, one end that steel cable is connected with bonnet is fixed and is wrapped on spooler, and spooler is fixed on bonnet.
Further, piston plate is provided with the hanger for being used for connecting steel cable.
Further, the first exhaust stack is provided with water seal cylinder, and water seal cylinder is located at outside gas chamber.
Further, the bottom of safe exhaust stack is nearby provided with nitrogen purging device.
Further, when gas chamber is blast furnace coal gas holder, safe exhaust stack can be put using blast furnace coal gas holder is original
Separate tube.
The beneficial effects of the invention are as follows：
1. generally, the open top of valve seat is covered and sealed completely by bonnet, when piston holder drives piston plate
When running to highest order, piston plate stretches steel cable completely, if piston continues to rise, steel cable will pull bonnet to depart from valve
Seat, such diffusion valve are in opening, and coal gas finally diffuses by the first exhaust stack and safe exhaust stack respectively from diffusion valve
Into air, the function of diffusing is realized.Then, with cabinet gas diffuse, piston Board position will decline until bonnet returns
Fall on valve seat and the open top of valve seat is covered and sealed completely, diffuse and stop.The apparatus structure is simple, and cost is low, from
Dynamic completion is opened and stopping is diffused, and safe operation, diffusion valve is located inside gas chamber, and service life is long, it is good to inhale effect of making an uproar.
2. using the attraction between magnet, it can both increase pressure in bonnet and valve base sealing and strengthen sealing effectiveness,
The stroke of bonnet can be guided and controlled during bonnet falling again, facilitate the cooperation of bonnet and valve seat to position.
3. valve seat and bonnet are sealed by the way of soft, scleroma is closed, sealed reliable.
4. when cabinet position is in lowest order, unnecessary steel cable is stored by spooler, prevents from winding.
5. if steel cable is directly anchored on piston plate not only connect not tightly, and be unfavorable for reclaiming, steel cable passes through hanger
It is connected, is completely embedded with piston plate, is easy to reclaim.
6. water seal cylinder can be cut off in the turnaround of unit of this emergency diffusion.
7. nitrogen purging device can purge in the turnaround of unit of this emergency diffusion to the bottom of safe exhaust stack, prevent
Only block and diffuse passage.
8. because blast furnace coal gas holder can be provided with exhaust stack, therefore original exhaust stack can be regard as this emergency diffusion
The safe exhaust stack of device, now, not only save man-hour and cost but also larger repacking need not be carried out to gas chamber.
