Description
Technical field
The utility model relates to a kind of seal, relates in particular to a kind of insulator arrangement that the electrical tar precipitator of tar is used in the coal gas that purifies.
Background technology
At present, in each family's purification coal gas, be extensive use of in the tar content field and arrived a kind of electrical tar precipitator, when purifying tar, guaranteeing user's usefulness gas quality, also alleviate the coking situation in all kinds of valves, pipeline and the heating furnace burner on gas-pipe line, in the burnt cylindrical shell of the electric fishing of the electrical tar precipitator under the prior art by hexagonal cellular precipitation utmost point, polar curve, weight, parts such as suspension bracket are formed up and down, cylinder top is distributed with three insulators and high voltage source introducing device, and its operation principle is as described below:
Electrical tar precipitator is being introduced external power supply behind silicon-controlled voltage regulation, again by rectification rises transformer boost reach operating voltage after, by cable access electric fishing Jiao, between plain conductor and metal pipe-wall, produce electric field, make and form the corona zone between the anode and cathode.Press electric field theory, cation is adsorbed in electronegative corona discharge electrode, and anion is adsorbed in the receiving electrode of positively charged; All negative ions that are ionized all are full of the whole space between corona discharge electrode and the receiving electrode.When the coal gas that contains impurity such as tar droplet during by this electric field, adsorbed the impurity of anion and electronics under the effect of electric field Coulomb force, move to that to discharge institute behind the receiving electrode electrically charged, and be adsorbed on the receiving electrode, thereby reach the purpose of Purge gas.And the impurity level on being adsorbed in receiving electrode can be discharged from the electrical tar precipitator bottom automatically to dirty time when being increased to greater than its adhesive force, mixes with blast furnace gas, coal gas of converter through the coke-stove gas of decoking, uses for the user.
And the main effect of the burnt insulator of the electric fishing of one of key components and parts of electrical tar precipitator is divided into two aspects, the one, high voltage direct current is introduced electric fishing Jiao, the 2nd, polar curve and the weight of inside played a supportive role, because the burnt electric pressure of using of electric fishing is generally all than higher, reach several ten thousand volts, therefore keeping the good insulation performance performance is to guarantee the key of electric fishing coke installation operate as normal, in order to guarantee the insulating properties of porcelain insulator, use electric heater that insulator inside is heated, when temperature-sensing probe detects the insulator internal temperature and is lower than 95 ℃, control heater gets and electric the inner space is heated, when temperature is higher than 110 ℃, stop heating, the insulation processing has all been carried out in insulator staving outside simultaneously, make the insulator temperature be higher than 95 ℃ all the time, to guarantee best insulation effect.
Yet, through practical for a long time, though the execute-in-place workman finds that the burnt insulator of electric fishing is closed structure (as shown in Figure 1), the external humidification air is difficult to enter, and inside is equipped with electric heater and assists heating simultaneously, guarantee that the insulator temperature is higher than 95 ℃ all the time, guaranteeing best insulation effect, but in actual use, the situation that the insulator dielectric performance descends often appears, cause equipment normally to move, main cause has following two aspects:
1) though the burnt staving housing contacts of the porcelain insulator under the prior art and electric fishing position is equipped with seal washer, but because seal washer only depends on the deadweight of porcelain insulator itself to compress, adding upper sealing washer begins to wear out in use for some time, there is small leakage inevitably, and coke-stove gas pressure is higher than the insulator internal air pressure in the burnt staving of electric fishing, coke-stove gas can be sneaked into insulator inside gradually, tar in the coal gas can condense upon on the porcelain insulator surface and form conductive layer, finally can destroy the insulating properties of insulator, cause the equipment can't operate as normal;
2) the burnt insulator of the electric fishing under the prior art is closed structure, though the external humidification air is difficult to enter, but because insulator is outdoor equipment, when disintegrating maintenance, if weather is relatively moister, humid air just is difficult to discharge after entering insulator inside again, and humid air is easy to cause electrion in the cohesion of porcelain insulator surface;
3) in addition, because coke-stove gas may be sneaked into insulator inside, coal gas is imflammable gas, so insulator uses the auxiliary electrical heating to have certain danger.
In sum, the burnt insulator of the electric fishing of the electrical tar precipitator under the prior art can't satisfy the needs of safety in production, so now need a kind of novel electrical tar precipitator burnt insulator of electric fishing, can eliminate the variety of problems of using electric heater under the prior art, and can stop coal tar and pollute internal unit and fuel gas and enter and bring potential safety hazard, and need be simple in structure, be convenient to popularize and use.
