Abstract
The invention relates to an insulating method of an insulator of an electric precipitator. The method comprises the following steps: on a basis of introducing out-coming steam into an insulator box, further introducing steam generated in a gas generating furnace in a region into the insulator box, wherein two steam introduction pipelines are provided with control switch valves; when the quantity of steam generated by the gas generating furnace is enough to maintain the temperature in the insulator box, closing the pipeline from which out-coming steam is introduced into the insulator box; and when the quantity of steam generated by the gas generating furnace is insufficient to maintain the temperature in the insulator box, opening the pipeline from which out-coming steam is introduced into the insulator box. The insulating method provided by the invention is small in use level of out-coming steam, low in cost and little in discharge.
Description
Technical field
The present invention relates to deduster technical field, specifically a kind of heat preserving method of electric cleaner insulator.
Background technology
Electric cleaner is a kind of gas purifying equipment, its operation principle utilizes high voltage electric field to make to be ionized with the gas of dust granules, electronegative dust granules is pole plate motion on the sunny side under the effect of electric field force, and be attracted on positive plate, the dust granules of positively charged moves to minus plate under the effect of electric field force, and being attracted on minus plate, dust granules is collected in ash bucket by rapping mode by cathode-anode plate, and the gas be purified then is discharged outside deduster.Electric cleaner has the advantage that energy consumption is low, gas treatment amount is large that efficiency of dust collection is high, equipment resistance is little, total, is applicable to high temperature, dust content is large, exhaust gas volumn is large operating mode, is widely used in the industries such as power plant coal-burning boiler, cement, metallurgy, petrochemical industry.
Electric cleaner high voltage supply part is distributed in the top of electric cleaner usually, be connected with corona discharge electrode by the insulator at electric cleaner top, insulator is a vitals of electric cleaner, insulator contacts with the high-temperature gas of electric cleaner interior, outside is then air dielectric, if external temperature is low, the High Temperature Gas of interior insulator is known from experience at condensed on inner walls Cheng Shui, reduce the resistance to pressure of insulator, maybe can produce punch-through and cause insulator surface shattered crack, compressive resistance reduces further, cause electric cleaner forced outage, so the external temperature of insulator must be greater than about internal air temperature 30-40 DEG C, ability is unlikely causes hydrogenesis, current exterior insulator is located in insulator box, pass into steam in insulator box to be incubated, the steam (external steam) that steam adopts thermal power plant boiler to provide, quantity of steam use amount is large, cost is high, and the steam that gas generator produces in region externally discharges when saturated, cause waste.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of external steam use amount little, cost is low, the heat preserving method of the electric cleaner insulator of emissions reduction.
The technical solution adopted in the present invention is: the heat preserving method providing a kind of electric cleaner insulator, cause on the basis in insulator box at external steam, the steam that gas generator in region produces also is guided in insulator box, two steam inlet line roads are equipped with gauge tap valve, when the quantity of steam that gas generator produces enough keeps the temperature in insulator box, close external steam and cause pipeline in insulator box; When the quantity of steam that gas generator produces keeps the temperature in insulator box not, open external steam and cause pipeline in insulator box.
In the steam that gas generator produces, part is used as the gasifying agent of gas generator.
The advantage of the heat preserving method of electric cleaner insulator of the present invention is: the steam redundance that gas generator in region produces can be utilized, when self-produced steam is not enough, changeable external steam uses, save the use amount of external steam, reduce cost, reduce the discharge capacity of excess steam, optimize the environment of Production Regional, the present invention improves front external steam flow reading average out to 2.2 tons/hour, external steam flow reading average out to 0 ton/hour after improvement, namely after improving, external steam 2.2 tons/hour within each hour, can be saved, every day can steam saving about 52.8 tons.In the winter time, because steam production is little, cold weather, still needs external steam to be incubated, and therefore, generally uses in 5-September, 5 totally months; Steam cost is 116.08 yuan/ton, then benefit is 52.8 × 30 × 5 × 116.08 ≈ 91.9 ten thousand yuan year.
Accompanying drawing explanation
Fig. 1 is the structural representation of steam pipework before improving.
Fig. 2 is the structural representation of steam pipework after improving.
In figure, 1, external steam pipework, 2, drum, 3, insulator box, 4, gas generator, 5, self-produced steam pipeline.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As Fig. 1, shown in Fig. 2, the heat preserving method of electric cleaner insulator of the present invention, refer to and cause on the basis in insulator box 3 at external steam, the steam produced by gas generator in region 4 is also guided in insulator box 3, two steam inlet line roads are equipped with gauge tap valve, external steam pipework 1 and self-produced steam pipeline 5 are equipped with steam flowmeter, insulator box 3 is built with thermal detector, the collection of each data, process and gauge tap valve can be controlled by control cabinet, when the quantity of steam that gas generator 4 produces enough keeps the temperature in insulator box 3, close external steam and cause pipeline in insulator box 3, when the quantity of steam that gas generator 4 produces keeps the temperature in insulator box 3 not, open external steam and cause pipeline in insulator box 3.
The present invention in the specific implementation, the steam that gas generator 4 produces converges in drum 2, steam in drum 2 is used as again the gasifying agent of gas generator 4, before improvement, the some vapor in drum 2 then will be discharged when gasifying agent is enough, can cause in insulator box 3 by the steam of this part after improvement, another introducing steam pipework of insulator box 3 is communicated with external steam pipework 1, by the switch of control valve control piper.
