Description
Technical field
The invention belongs to thermal power plant environmental technology fields, are related to a kind of wet electric high frequency electric source insulator chamber pressurize sealing
Structure.
Background technology
As country carries forward vigorously the continuous improvement and coal unit minimum discharge of environmental requirement with transforming, wet type electricity removes
Dirt is used widely in minimum discharge transformation project, and achieves preferable dust removing effects.Currently on the market, Horizontal wet
There are mainly two types of electric high frequency electric source insulator chamber seal forms：One kind is that conventional hermetic and logical sealing air side are done to insulator chamber
Case；Another kind is by improving insulator chamber seal to completely enclosed state without setting sealing air.Two kinds of form situations are as follows：
1) sealing air form is led to
Due to not fully being sealed inside wet electrical isolation seed cell and air and wet electricity, if not doing measure, during wet electricity operation
Inside is positive pressure, and wet flue gas will leak to insulator chamber and where it in box beam at gap, and cause dewing corrosion.To avoid
It is such to happen, sealing air is passed through in insulator chamber, inside forms positive pressure, allows its pressure higher than wet electric inside smoke pressure
Power, it is internal that sealing air will be pressed into wet electricity so that wet flue gas can not leak, and play the role of smoke impervious.
It is completely closed to the advantage is that insulator chamber need not be accomplished, simple structure, construction are easy.But its energy consumption compared with
Height, wind turbine need regular maintenance.
Since logical sealing air form needs the seal fan that continuously puts into operation, and at least ensure that the fortune one of wind turbine one is standby, avoid because of wind
Machine failure is stopped transport so that smoke spillage, causes related facility corrosion and damage；It to be asked since wind turbine belongs to rotating machinery there are lifetimes
The damage being likely to occur during topic and operation, therefore the form needs periodically to carry out the facilities such as seal fan repair and maintenance, increases
Add human input.
2) form is fully sealed
Insulator chamber is designed to be fully sealed, reaches its inside of isolation and is contacted with extraneous.Inside and outside insulator chamber
Isolation, is not required seal fan, compared to sealing air scheme, does not have wind turbine power consumption in operational process.But difficulty is fully sealed
Larger and durability is not high.It is feasible in the sealing theory of this kind of form, it can actually be influenced because of processing, installation accuracy or mounting process
Its seal causes insulator chamber poorly sealed, and wet flue gas is caused to leak and corrodes carbon steel component or even influences Electrical Safety.
The content of the invention
It it is an object of the invention to overcome the shortage of prior art, provides a kind of rational in infrastructure, takes into account energy saving and reliable
Property wet electric high frequency electric source insulator chamber pressurize sealing structure.
To achieve the above object, present invention employs following technical schemes：
Wet electricity high frequency electric source insulator chamber pressurize sealing structure includes compressed air line, automatic valve, pressure transmitter, pressure
Contracting air interface and wet electric high frequency electric source insulator chamber, the wet electric high frequency electric source insulator chamber is totally-enclosed structure, in Qi Ding
Portion sets compressed air interface；The compressed air line is connected to compressed air interface；The compressed air hose road is provided with
Automatic valve and pressure transmitter.
The control method of wet electricity high frequency electric source insulator chamber pressurize sealing structure, includes the following steps：
First, compressed air line introduces compressed air into wet electric high frequency electric source insulator chamber and forms positive pressure higher than flue gas
Pressure is used to seal；
Secondly, when pressure transmitter feedback pressure is less than 50kPa, automatic valve is opened, compressed air line passes through compression
Air interface tonifying Qi；When pressure transmitter feedback pressure is higher than 100kPa, closes automatic valve and stop tonifying Qi.
The beneficial effects of the invention are as follows：Wet electricity high frequency electric source insulator chamber pressurize encapsulating method passes through wet electric high frequency electric source
The full-closed structure design of insulator chamber, and it is aided with compressed air pressurize, simple system is energy saving.

Fig. 1 is schematic structural view of the invention；
Reference sign：Compressed air line 1, automatic valve 2, pressure transmitter 3, compressed air interface 4, high frequency electric source
Insulator chamber 5.
Specific embodiment
The present invention is described further with reference to embodiment.The explanation of following embodiments is only intended to help to understand this
Invention.It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, also
Can to the present invention some improvement and modification can also be carried out, these improvement and modification also fall into the protection domain of the claims in the present invention
It is interior.
As shown in Figure 1, the wet electric high frequency electric source insulator chamber pressurize encapsulating method of the present embodiment, including compressed air line
1st, automatic valve 2, pressure transmitter 3, compressed air interface 4, wet electric high frequency electric source insulator chamber 5.Wet electricity high frequency electric source insulator
Room 5 is designed as totally-enclosed structure, compressed air interface 4 is set at the top of it, compressed air is by solenoid valve and wet electric high-frequency electrical
The compressed air interface 4 at 5 top of source insulator chamber keeps wet electric high frequency electric source insulation into wet electric high frequency electric source insulator chamber 5
Pressure is higher than its external pressure in seed cell 5, forms positive pressure higher than flue gas pressures, avoids smoke spillage exhausted into wet electric high frequency electric source
Edge seed cell 5, so as to achieve the purpose that sealing.The system effectively prevents wet electric high frequency electric source insulator chamber 5 and condenses, and cancels simultaneously
Conventional enclosed air system, reaches energy-saving effect.
Automatic valve 2 and pressure transmitter 3 are provided on the compressed air line 1, when 3 feedback pressure of pressure transmitter is low
When low report value, 2 tonifying Qi of automatic valve is opened；When 3 feedback pressure of pressure transmitter is higher than high report value, automatic valve 2 is closed, is stopped
Tonifying Qi.The low report value of pressure and high report value are respectively 50kPa and 100kPa.
The control method of wet electricity high frequency electric source insulator chamber pressurize sealing structure, includes the following steps：
