Description
Technical field
The present invention relates to gas chamber technical field, and in particular to a kind of brush seal installation of gas chamber.
Background technology
As low-carbon economy is increasingly becoming various countries' economy and the target of industrial development, China's environmental policy is also gradually improved,
Low-carbon production, which has become, puts problem very urgent in face of Ferrous Metallurgy equal energy source expendable enterprise.Wherein, gas chamber is made
An important device of comprehensive utilization of energy rate is improved for iron and steel enterprise, it is using more and more extensive.The effect of gas chamber is back
Receipts are handled up transient surplus coal gas caused by unbalanced production, and can obtain pipe network voltage stabilizing and energy-conservation with the cooperation regulation of interruptible customer
Ideal effect.
Gas chamber is divided into wet gas cabinet and dry gas holder two types, due to the quantity of wastewater effluent of wet gas cabinet
Greatly, it is serious to environmental hazard, therefore application is few, generally uses dry gas holder at present.Dry gas holder is according to its sealing side
Formula is different to be divided into sealed and rubber diaphragm sealed three kinds of the formula of thin oil seal formula, drier oil again.Thin oil seal formula and the sealed coal of drier oil
Gas holder is complicated, and maintenance difficulties are big, and disposable investment is higher；Although rubber diaphragm sealed formula gas chamber sealing means letter
Single, good airproof performance, maintenance workload is few, but for exploitation Large Copacity, stability is good, the convenient gas chamber of working service this become
For gesture, bottleneck problem be present, after being increased such as gas chamber capacity, rubber membrane is highly increased, it is necessary to which rubber film strength is higher, so
And this is limited by the manufacturing process of current rubber membrane.As can be seen here, the gas chamber of three of the above conventional seals mode is in coal
Certain drawback be present in gas holder maximization development, hinder the maximization process of gas chamber.
The content of the invention
The technical problem to be solved in the present invention is, for existing gas cabinet sealing above shortcomings, there is provided Yi Zhongmei
The brush seal installation of gas holder, meet gas chamber operation demand, suitable for various amount of capacity, stability is good, easy to maintenance.
The present invention is that technical scheme is used by solving above-mentioned technical problem：
A kind of brush seal installation of gas chamber, between the piston of gas chamber and the inwall of cabinet, it includes hair
Brush holder, hairbrush and wearing layer, woollen brush base are connected with piston, and the multi-layer intercrossed arrangement of hairbrush is arranged on woollen brush base, and wearing layer is painting
The wear-resistant paint being put on cabinet madial wall.
By such scheme, the hairbrush is fine wire warp architecture.
By such scheme, the bristle of the hairbrush is compound bending structure（So that meet piston between hairbrush and woollen brush base
Seal request when moving up and down）.
By such scheme, the woollen brush base uses magnetic brush seat, and piston uses the metal knot coordinated with magnetic brush seat
Structure.
The operation principle of the present invention：Hairbrush is fine wire warp architecture, has low fragility and high tenacity, ensures two-way shifting
It is not easily broken when dynamic, due to forming small gap, and the inhomogeneities in these gaps between the fine wire of hairbrush, makes
Even incoming, which enters in the brush filament of hairbrush, just becomes uneven, ensures the inhomogeneities of flowing because brush wire bundle destroys flowing,
Fluid is set to generate self sealss effect.Wearing layer prevents cabinet from being scratched by the bristle of hairbrush, while reduces the frictional dissipation of bristle.
Beneficial effects of the present invention：The sealing device is applied to the gas chamber of various amount of capacity, and has adaptivity,
Simple in construction, stability is good, easy to maintenance, it is only necessary to regularly replaces hairbrush, cost is cheap；Using the sealing device, gas chamber without
It is small to imitate volume, greatly reduces construction cost.

Embodiment
Technical solution of the present invention is described in detail with reference to the accompanying drawings and examples.
Shown in 1 ~ Fig. 3 of reference picture, gas chamber is mainly made up of 2 two main elements of cabinet 1 and piston, and usual cabinet 1 is
Cylindrical structural（As shown in Figure 1）, piston 2 is disc-shaped structure（As shown in Figure 3）, piston 2 is in the presence of coal gas 3 in cabinet
Moved up and down in 1, realize storage coal gas 3 and stablize the function of the pressure of coal gas 3.Require to live when piston 2 moves up and down in cabinet 1
Good seal between plug 2 and the inwall of cabinet 1.
As shown in figure 4, the brush seal installation of gas chamber of the present invention, installed in the inwall of piston 2 and cabinet 1 it
Between, including woollen brush base 4, hairbrush 5 and wearing layer 6, woollen brush base 4 is connected with piston 2, with piston 2 together in cabinet 1 on move down
Dynamic, to make woollen brush base 4 and piston 2 easy to connect firmly, using magnetic brush seat 4, piston 2 uses to be coordinated with magnetic brush seat 4
Metal structure；The multi-layer intercrossed arrangement of hairbrush 5 is arranged on woollen brush base 4, and hairbrush 5 is fine wire warp architecture, and low fragility is high
Toughness, ensure to be not easily broken during way moving, the bristle that the fine wire of hairbrush 5 is formed is compound bending structure；Wearing layer 6 is
The wear-resistant paint being applied on the madial wall of cabinet 1, prevent cabinet 1 from being scratched by the bristle of hairbrush 4, while reduce the friction damage of bristle
Consumption.
Due to forming small gap, and the inhomogeneities in these gaps between the fine wire of hairbrush 5, make uniform
Incoming, which enters in the brush filament of hairbrush 5, just becomes uneven.Ensure the inhomogeneities of flowing because brush wire bundle destroys flowing, make stream
Body generates self sealss effect.
Gas chamber Light Condition is as shown in figure 1, now piston 2 is in the bottom of gas chamber cabinet 1.When coal gas 3 start into
When entering gas chamber, the low pressure of piston 2 is higher than upper pressure, i.e. coal gas 3 can enter in the bristle of hairbrush 5, because brush wire bundle is broken
It is broken the flow behavior of coal gas 3 and it is flowed uneven, so as to forms sealing effectiveness.
Gas chamber full load condition is as shown in Fig. 2 now piston 2 is in the top of gas chamber cabinet 1.When coal gas 3 start from
When gas chamber is discharged, the upper pressure of piston 2 is higher than low pressure, i.e. air can enter in the bristle of hairbrush 5, because brush wire bundle is broken
It is broken the flow behavior of air and it is flowed uneven, so as to forms sealing effectiveness.
Because the bristle of hairbrush 5 is compound bending structure so that meet that piston 2 moves up and down between hairbrush 5 and woollen brush base 4
When seal request.
The sealing device is a kind of contact, and the sealing that energy is adaptive, the gas chamber available for various capacity.Due to brush
Hair is flexible, adapts to gap uneven between piston 2 and the inwall of cabinet 1.The sealing device structure is simple, and maintenance is small,
Only need to regularly replace hairbrush 5.
Obviously, above-described embodiment is only intended to clearly illustrate example of the present invention, and is not to the present invention
The restriction of embodiment.For those of ordinary skill in the field, spirit under this invention is extended out aobvious and easy
Among the change or variation seen are still in protection scope of the present invention.
