Description
Technical field
The utility model heat exchange electric cleaner relates to the environmental protection cleaner that a kind of fume afterheat utilizes.
Technical background
The high-voltage electrostatic dust separator that is used at present to administer dust pollution both at home and abroad has only dedusting function, and the flue-gas temperature that has is very high, requires deduster to have high-temperature stability.
Summary of the invention
The purpose of the utility model heat exchange electric cleaner is to propose a kind of electric cleaner with hot-swap feature, and dedusting and heat exchange function are combined together, in dedusting, extracts the heat energy in the flue gas.The heat exchange electric cleaner is by air intake vent, casing, charged negative pole, charged positive pole, tubulation heat exchanger, positive plate, and screening electrode, air outlet, current-limiting resistance and high voltage source are formed.It is characterized in that, multiple tracks tubulation heat exchanger is set in casing, between every twice tubulation heat exchanger, charged negative pole and charged positive pole are set, charged negative pole and charged positive pole are by the alternate setting of row, in the casing posterior transversal screening electrode is set, on screening electrode, be provided with positive plate, each positive plate equidistant parallel is provided with, between per two adjacent positive plates, charged negative electrode is set, charged negative pole directly or by current-limiting resistance links to each other with the negative polarity output of high voltage source, charged plus earth, the tubulation heat exchanger, screening electrode and positive plate all link to each other with casing, casing ground connection, the positive polarity output terminal of high voltage source links to each other with casing and ground connection, has recirculated water to pass through in the tubulation heat exchanger.
The tubulation heat exchanger links to each other with the positive polarity output terminal of high voltage source, so the tubulation heat exchanger both played heat exchange action, is again the anode of electric cleaner, plays dust agglutination.
The dust-laden high temperature gas flow enters casing from air intake vent, and when flowing through the tubulation heat exchanger, air-flow is evenly distributed, and the heat in the air-flow is exchanged simultaneously, and gas flow temperature descends.When air flow stream is crossed electric field between charged negative pole and the charged positive pole, dust in the air-flow by lotus with positive electricity or negative electricity, the dust of positively charged and electronegative dust condense and sedimentation mutually, when air-flow process tubulation heat exchanger, heat in the air-flow is passed to tubulation, tubulation is passed to the interior water of pipe with heat, and water temperature raises, and gas flow temperature reduces.Tubulation links to each other with the positive source output, and tubulation repels the dust of positively charged, attract and pounce on to collect electronegative dust, so the tubulation heat exchanger has the dual-use function of heat exchange and control of dust.
Owing to have water to flow through in the tubulation, no matter therefore how high the temperature of dusty gas have, the temperature of tubulation is in below the 100 all the time, has so just determined tubulation heat exchange electric cleaner to have resistant to elevated temperatures characteristic.
When the flue gas process positive plate of process cooling and the space of charged negative electrode, the dust in the air-flow is by charged, and screening electrode stops the dust of positively charged to pass through, and screening electrode and positive plate are pounced on the electronegative dust of collection.
And traditional electric cleaner does not have hot-swap feature, and deformation at high temperature takes place its positive plate, and when positive plate produced deformation, electric cleaner was with regard to cisco unity malfunction.
Description of drawings
Accompanying drawing is a heat exchange electric cleaner theory structure schematic diagram
In the drawings, 1 is air intake vent, and 2 is casing, and 3 is charged negative pole, and 4 is charged positive pole, and 5 is tubular heat exchanger, and 6 is positive plate, and 7 is screening electrode, and 8 is air outlet, and 9 is high voltage source, and 10 is current-limiting resistance.
The specific embodiment
Tubulation heat exchange electric cleaner as shown in the figure
In the drawings, set into air port 1 at the front end of casing 2, the rear end sets out air port 8, is provided with the multiple tracks tubular heat exchanger at the first half of casing, optional quarter bend of the tubulation of these tubular heat exchangers or pipe, or adopt finned tube, to improve heat exchanger effectiveness.Charged negative pole 3 is set with charged anodal 4 between every twice tubular heat exchanger, charged negative pole 3 is pressed row alternately with charged anodal 4, posterior transversal at casing is provided with screening electrode, positive plate is set on screening electrode, each positive plate parallel equidistant and vertical with screening electrode, between per two positive plates, charged negative pole is set, each charged negative pole is by current-limiting resistance 10 row that link to each other with the negative pole of high voltage source 9, charged positive pole, heat exchange of heat pipe, positive plate and screening electrode all link to each other with casing, casing ground connection, the positive pole of high voltage source links to each other with casing and ground connection, passes to recirculated water in the tubular heat exchanger.
Deduster in use, air intake vent and flue pipeline join, air outlet and air-introduced machine join, tubular heat exchanger links to each other with circulation.
Under the effect of air-introduced machine, flue gas enters housing through air intake vent, at first through being arranged on the tubular heat exchanger that the place, air port is made up of quarter bend, this tubular heat exchanger plays three kinds of effects, the one, when air-flow passes through intensive tubulation, air-flow is evenly distributed, the 2nd, tubular heat exchanger and air-flow carry out heat exchange, and the water temperature in the heat exchanger raises, and gas flow temperature lowers, waste heat in the gas is utilized, the 3rd, when gas was flowed through tubular heat exchanger, the dust that inertia is bigger in the gas impinged upon the surface of tubulation, has changed the direction of motion, with flow separation, the bigger dust of quality is by filtering.
Exist the bigger electric charge field of gradient between charged negative pole and the charged positive pole, under the effect of current-limiting resistance, the corona discharge between charged negative pole and the charged positive pole is stable.
When preliminary charged negative pole of airflow passes of lowering the temperature and the space between the charged positive pole, under effect of electric field, with positive electricity or negative electricity, positively charged and electronegative dust condense and sedimentation mutually the dust in the air-flow by lotus.
When air-flow passed through the tubular heat exchanger of charged negative pole and charged anodal back, the heat energy in the further exchanging gas of tubular heat exchanger descended gas temperature.Because tubular heat exchanger links to each other with the positive pole of power supply, tubular heat exchanger attracts to pounce on the electronegative dust of collection, repel the dust of positively charged, and electroneutral gas can pass from tubular heat exchanger.
Air-flow is during through the electric field between charged negative pole and the positive plate, and the dust in the air-flow is by charged, and screening electrode and positive plate are pounced on the electronegative dust of collection, repel electronegative dust, and though positively charged or electronegative dust is difficult to pass through screening electrode.Therefore say that screening electrode has good shielding buffer action to charged dust.Cleaned gas is got rid of from air outlet.
Heat-exchange electric dust remover organically combines dedusting and heat exchange together, and it is two to have the waste heat of taking full advantage of and a dedusting Heavy function, this deduster has the characteristics such as simple in structure and high temperature resistant.
