Abstract
A hot air sealing venturi dustproof cover for an electric dust collector insulating piece comprises a dustproof cover. The dustproof cover is connected to the lower portion of an insulating cone sleeve of a discharging electrode hanging system. Blowback hot air enters the dustproof cover from the top of the insulating cone sleeve from top to bottom. The dustproof cover is of a venturi structure. The diameter of the upper portion of the dustproof cover is large, and a large-diameter segment is formed. The diameter of the lower portion, close to electric field smoke, of the dustproof cover is fast decreased, and a venturi annular structure is formed. Due to the fact that the dustproof cover is of the venturi structure, the situation that smoke in an electric dust collector electric field is sealed through the flowing speed of air flow does not need to be considered; hot air staying time is prolonged, and heating of the insulating piece is facilitated; meanwhile, the situation that the smoke in the electric dust collector electric field flows into the insulating cone sleeve through the dustproof cover is effectively prevented; the dustproof effect of the dustproof cover is greatly improved on the premise that the blowback hot air amount is not increased; and meanwhile, time consumed when the insulating piece is heated through hot air is prolonged.
Description
Technical field
The invention belongs to environmental project electric cleaner technical field, be specifically related to a kind of electric cleaner insulating part hot blast sealing Wen dust cover.
Background technology
Electric cleaner system utilizes electrion, electrostatic dust collection to reach the environmental protection equipment of dedusting object.Under discharge electrode is operated in high-voltage state, the suspension strut of discharge electrode relies on the insulating part such as electroceramics or quartz.Suspension strut part is made up of two insulation columns or insulation tapered sleeve cylinder suspension strut discharge electrode, supported and suspended section lower and Electric Field in ESP adjacent part, and the general dust cover that adopts prevents flue gas from " scurrying into " insulating part inside.The diameter of dust cover should be moderate, and flue gas cannot be stoped time excessive " to scurry into ", and too small cover body and the suspension rod of causing again discharges and affect voltage of electric field.
Hot blast sealing purging technology is that the cleaned air after utilizing heating heats insulating part in incubator, purges, pressure-fired sealing is formed in incubator, prevent the flue gas in electric cleaner from " altering " and enter incubator " pollution " insulating part, this technology is used widely.Hot blast enters cone sleeve inner from tapered sleeve cylinder top drilling, is mixed into electric cleaner flue gas by dust cover.
The meeting of too much hot blast air quantity increases the air leak rate of air curtain of deduster greatly.Hot blast deficiency in draught, the flue gas of Electric Field in ESP inside can pass through dust cover, and " to scurry into " insulation tapered sleeve inner, causes insulating part dust, creepage, thus cause electric cleaner operational efficiency to decline.
Therefore, under the prerequisite do not increased or reduce hot blast air quantity in right amount, prevent flue gas from entering insulation cone sleeve inner by optimal design dust cover form, both can reduce hot air heat exchange energy consumption, and deduster air leak rate of air curtain can be reduced again.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, a kind of electric cleaner insulating part hot blast is the object of the present invention is to provide to seal Wen's dust cover, flue gas in effective prevention Electric Field in ESP " scurries into " insulation cone sleeve inner by dust cover, extend the hot blast time of staying, be beneficial to insulating part heating.
To achieve these goals, the present invention adopts following scheme:
A kind of electric cleaner insulating part hot blast sealing Wen dust cover, comprise dust cover 1, dust cover 1 is connected to insulation tapered sleeve cylinder 2 bottom of discharge electrode suspension 3, blowback hot blast enters dust cover 1 from top to bottom by tapered sleeve cylinder 2 top of insulating, dust cover 1 adopts Venturi tube structure, and its upper diameter is large, forms enlarged diameter section 1-1, bottom contiguous electric field flue gas partial dust cover diameter reduces rapidly, forms venturi loop configuration 1-2.
The internal diameter of described venturi loop configuration 1-2 is greater than the minimum arcing distance of electric cleaner.
Advantage of the present invention is:
Because dust cover 1 adopts Venturi tube structure, utilizing air-flow velocity to seal flue gas in Electric Field in ESP without the need to considering, extending the hot blast time of staying, be beneficial to insulating part heating; Effectively stop the flue gas in Electric Field in ESP " to scurry into " insulation cone sleeve inner by dust cover simultaneously.Under the prerequisite not increasing blowback hot blast air quantity, substantially increase the dust-proof effect of dust cover 1, extend the heat time of hot blast to insulating part simultaneously.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
With reference to accompanying drawing, a kind of electric cleaner insulating part hot blast sealing Wen dust cover, comprise dust cover 1, dust cover 1 is connected to insulation tapered sleeve cylinder 2 bottom of discharge electrode suspension 3, blowback hot blast enters dust cover 1 from top to bottom by tapered sleeve cylinder 2 top of insulating, dust cover 1 adopts Venturi tube structure, its upper diameter is large, form enlarged diameter section 1-1, bottom contiguous electric field flue gas partial dust cover diameter reduces rapidly, form venturi loop configuration 1-2, hot-air flow is in venturi loop configuration 1-2 place restricted flow, when the flow section by reducing, there is the phenomenon that flow velocity and flow increase in fluid, its flow velocity and flow section amass and are inversely proportional to.
The internal diameter of described venturi loop configuration 1-2 is greater than the minimum arcing distance of electric cleaner.
Operation principle of the present invention is:
Hot blast is when by dust cover 1 top enlarged diameter section 1-1, and flow velocity is lower, and the hot blast time of staying is long, is beneficial to insulating part heating; Hot blast is when by dust cover 1 bottom venturi loop configuration 1-2, and local forms high velocity air rapidly, effectively stops the flue gas in Electric Field in ESP inner by dust cover 1 " scurrying into " insulation tapered sleeve cylinder 2.
