According to the present invention, the special separation solution is adopted to soak the insulators, such that the insulators and the biomass fuel gas are completely separated, the insulator performance reducing caused by attachment of the impurity on the surface can be avoided, the biomass fuel gas high-voltage electrostatic decoking device can have the sufficiently high voltage and the sufficiently high current density, the separation effect of tar and dust is improved, and the efficient and stable system operation is ensured.
Description
Technical field
The present invention relates to a kind of seal, specifically a kind of seal of biological fuel gas high voltage electrostatic detarrer.
Background technology
Biological fuel gas also has higher tar and dust content after comprising other mode process such as spray washing, can not meet the requirement of gas electricity generator.Must adopt high voltage electrostatic detarrer separating tar and dust again, the height of separating effect is that the electrostatic field intensity produced by electric pressure and current density determines.Good tar separation effect just can must reach under having enough current density condition higher than 35kv at voltage, and the higher separating effect of voltage is better.And insulation technology determines electric pressure and the current density of high voltage electrostatic detarrer.
What the insulation of the high voltage electrostatic detarrer of current China adopted is add wall bushing composition with suspension insulator, and all insulators are all exposed in biological fuel gas.Contain the materials such as tar, dust, steam due to biological fuel gas, these matter-poles are easily attached to the surface of insulator, reduce the insulating properties of insulator.On market, the insulator of high voltage withstand class bulky being unfavorable for installs, expensive cost is high, there are surface attachments destruction insulating properties still can not deal with problems because of as easy as rolling off a log at all, the electric pressure required by high voltage electrostatic detarrer and current density cannot be met, affect the separating effect of tar and dust, the electrical breakdown of insulator is caused to damage time serious, the normal operation of influential system.Based on above factor so general voltage is about 30kv, the biomass gas tar oil content after process is 50mg/Nm
3within.Or the operation of gas engine can be affected and cause the blocking of pipeline.
Summary of the invention
The object of the present invention is to provide a kind of seal improving the biological fuel gas high voltage electrostatic detarrer of tar and dust separation effect, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of seal of biological fuel gas high voltage electrostatic detarrer, comprise insulator chamber and insulator, described insulator is arranged in insulator chamber, the insulating liquid of isolation biological fuel gas is filled with in insulator chamber, multiple insulator chamber is evenly arranged on the side of high voltage electrostatic detarrer cylindrical shell and is in same plane, an insulator chamber forms wall bushing through cylindrical shell, and the top of insulator chamber is connected and fixed by support, and pedestal lower end hangs the polar filament dish of high voltage electrostatic detarrer.
As the further scheme of the present invention: described insulator chamber is provided with three.
As the present invention's further scheme: the material of described insulator is polymer composite.
Compared with prior art, the invention has the beneficial effects as follows: soak insulator with special insulating liquid, make insulator and biological fuel gas completely isolated, avoid the performance reducing insulator because of impurity attaching surface, make biological fuel gas high voltage electrostatic detarrer have sufficiently high electric pressure and current density, improve the separating effect of tar and dust, ensure system high efficiency, stable operation, extend the service life of gas engine, reduce the maintenance cost of gas engine.
