Description
Technical field
The utility model is related to a kind of emission control system of fume emission technical field, more particularly to a kind of to open pressure
The adjustable chimney venting of dust explosion diffusion valve of power.
Background technology
Secondary combustion chamber is generally provided with the hazardous waste handling process device such as municipal refuse, medical waste, to kiln
The poison gas of middle generation carry out second-time burning, and air is entered by main chimney after harmless treatment.In view of kiln and secondary
Combustion chamber periodically can carry out overhauling etc. the situation of non-normal emission, and secondary combustion chamber generally carries diffusing chimney.Due to secondary combustion
Indoor generally negative pressure is burnt, so being needed on diffusing chimney with valve.To prevent air from entering secondary combustion chamber, valve is usually
Close and only open when needed.In addition, situation about being exploded in second-time burning room happens occasionally, in order to avoid in second-time burning
Secondary combustion chamber is not caused damage, it is necessary to the pressure that explosion time is produced is discharged from chimney during indoor generation explosion accident
Go.At present, existing diffusion valve normally only has switching function, and the function of blast pressure is not drained, so, design is a kind of
Simultaneously there is the diffusion valve that switch diffused and drained blast pressure function to seem particularly necessary.
The content of the invention
To overcome the shortcomings of the existing technology, the utility model provides a kind of adjustable chimney venting of dust explosion diffusion valve of Opening pressure,
Simple structure, it is easy to use, can be needed to provide diffusion function according to production, while having excretion burning detonation inside pressure again
Function, eliminates influence of the secondary combustion chamber blast to main equipment, protects main equipment, and venting of dust explosion Opening pressure can basis
Need regulation.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of adjustable chimney venting of dust explosion diffusion valve of Opening pressure, including cigarette cap, base, support, assembly pulley, steel wire rope, match somebody with somebody
Weight and drive device, it is characterised in that the base is fixed on chimney port, and support is fixed on chimney, and cigarette cap falls in base
In, and be connected with steel wire rope, the rack-mount assembly pulley of steel wire penetrating is sequentially connected with counterweight, drive device.
Coordinated by circular conical surface between the cigarette cap and base.
The inside dimension of support 1-3mm bigger than the outside dimension of cigarette cap.
The counterweight is made up of sinker and balancing weight, and wherein sinker one end is connected with steel wire rope, the other end with drive
Device is connected；Balancing weight is N number of, and the balancing weight that multiple varies in weight is placed on sinker, and the quantity of balancing weight can be as needed
Increase and decrease.
The weight of the counterweight by adjusting the quantity of balancing weight, that is, adjusts counterweight and cigarette less than or equal to the weight of cigarette cap
Weight difference between cap, it becomes possible to realize the Opening pressure of adjustment cigarette cap.
Compared with prior art, the beneficial effects of the utility model are：
Simple structure, it is easy to use, can be needed to provide diffusion function according to production, while having excretion combustion chamber implosion again
The function of fried pressure, eliminates influence of the secondary combustion chamber blast to main equipment, protects main equipment, and venting of dust explosion opens pressure
Power can be adjusted as needed.

Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1-Figure 3, a kind of adjustable chimney venting of dust explosion diffusion valve of Opening pressure described in the utility model, including cigarette
Cap 2, base 3, support 4, assembly pulley 5, steel wire rope 6, counterweight 7 and drive device 8, the base 3 are fixed on the port of chimney 1,
Support 4 is fixed on chimney 1, and cigarette cap 2 falls in base 3, and is connected with steel wire rope 6, and steel wire rope 6 is passed through on support 4
Assembly pulley 5 be sequentially connected with counterweight 7, drive device 8.
Coordinated (see Fig. 2) by circular conical surface between the cigarette cap 2 and base 3, it is ensured that sealing, prevent air from entering secondary combustion
Burn room.
The inside dimension of the support 4 1-3mm bigger than the outside dimension of cigarette cap 2, facilitates cigarette cap 2 to be hung down along the inside of support 4
Directly move up and down.
The counterweight 7 is made up of sinker 9 and balancing weight 10, and wherein the one end of sinker 9 is connected with steel wire rope 6, the other end
It is connected with drive device 8；Balancing weight 10 is N number of, and the balancing weight 10 that multiple varies in weight is placed on composition counterweight 7 on sinker 9, matches somebody with somebody
The quantity of pouring weight 9 can increase and decrease as needed.
The weight of the counterweight 7 had both ensured to be sealed between cigarette cap 2 and base 3 less than or equal to the weight of cigarette cap 2, meanwhile, when
There is explosion time in secondary combustion chamber, the pressure of generation can rapidly jack-up cigarette cap 2 draining blast pressure.By adjusting balancing weight 10
Quantity, that is, adjust the weight difference between counterweight 7 and cigarette cap 2, it becomes possible to realize the purpose of the Opening pressure of adjustment cigarette cap 2.
Operation principle：
1) generally, cigarette cap 2 falls in base 3, between by circular conical surface coordinate (see Fig. 2), it is ensured that sealing, prevent
Air enters secondary combustion chamber.
2) when needing to diffuse, operation drive device 8 pulls steel wire rope 6 to lift cigarette cap 2 by assembly pulley 5, you can realize
Diffusion function.
3) during working, once blast occurs in secondary combustion chamber or stove produces pressure, i.e., when the gas in chimney 1 is made
During the difference of the weight for exceeding the weight and counterweight 7 of cigarette cap 2 with the pressure on cigarette cap 2, cigarette cap 2 will realize excretion by jack-up
Blast pressure (venting of dust explosion) simultaneously protects whole process system to act on.Obviously, by adjusting the quantity of balancing weight 10, that is, counterweight 7 is adjusted
With the weight difference between cigarette cap 2, it becomes possible to realize the Opening pressure of adjustment cigarette cap 2.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any one skilled in the art in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its inventive concept is subject to equivalent or change, should all cover protection domain of the present utility model it
It is interior.
