Abstract

A flow-guiding condensing deduster features that a guide tube type mixed flow-device composed of flue partition, flow-guiding tube and inner surface through the main body is arranged at lower part of main body so as to omit circulating water pump and sprayer, and a cyclon suction type condensing cleaner composed of settling chamber and cyclon sucker is arranged at upper part of main body to condense the water vapour containing dust into liquid drops which are then centrifugally separated out. Its advantages are high desulfurizing and dedusting effect and low cost.

Description

A kind of flow-guiding condensing duster and technology thereof

The invention belongs to a kind of deduster and technology thereof that the environmental protection aspect is used, particularly a kind of flow-guiding condensing duster and technology thereof belong to processing technique field.

In the prior art purified treatment is carried out in the stove atmosphere pollution, wet type desulfurizing dust collector that is adopted and technology thereof, as products such as granite dusters, owing to aspect mixed flow, can not accomplish even mixed flow and can not accomplish again aspect separating that steam is separated fast with air, so, in the water yield hour, tend to occur dragging the discharging that exceeds standard of floating part sulfur dioxide and oxynitrides, then when the water yield is big, air-introduced machine band water appears again easily, its operation and instability, efficient is low, maintenance cost is high, can not satisfy the use needs.

The purpose of this invention is to provide a kind of flow-guiding condensing duster and technology thereof, mainly below the deduster body, be combined into a catheter type flow mixing device by body by buffler and mozzle and inwall, thereby can realize the mixed flow effect of deduster without water circulating pump and shower nozzle, in addition, above the deduster body, be provided with the whirlwind suction-type condensation purifier of forming by expansion chamber and cyclone type inhalator, therefrom a large amount of cold airs is sucked in the expansion chamber and mix with flue gas by the cyclone type inhalator, making the steam that is inclusive with flue dust obtain forming drop after the condensation separates rapidly with air in centrifugal motion, promptly realize the purpose that it purifies air by condensation cleverly, thereby remedy the deficiencies in the prior art, effectively improve the desulfurization dust-removing efficiency of deduster, reduce operating cost.

A kind of flow-guiding condensing duster provided by the invention and technology thereof, implement by the following technical programs: above the deduster body, be provided with whirlwind suction-type condensation purifier, wherein, on the aperture plate of clarifier bottom near several centrifuge blades that is fixed with of the edge-perpendicular of mesopore, on centrifuge blade, be fixed with flow distribution plate, and near the outward flange of aperture plate vertical be fixed with several louvre blades, on louvre blade, be fixed with intercepter plate, on intercepter plate, face down drain tube is installed, for the purpose that is able to suck surrounding air makes the guiding of centrifuge blade opposite with the guiding of louvre blade, for a side that is gone in aperture plate in separator and emission shunting is shaped on hole draining downwards, promptly by aperture plate, centrifuge blade, louvre blade, intercepter plate, flow distribution plate constitute a cyclone type inhalator mutually.Above inhalator, be combined into an expansion chamber by discharge duct, anticorrosion liner plate, metal angle bead, expansion chamber and inhalator are combined and constitute whirlwind suction-type condensation purifier.Below clarifier, utilize the deduster body of Bolt Connection by flange, flue tube place in its bottom utilizes outer wall to be provided with flue shrouding and buffler, with several in the horizontal direction the mozzle of both-side opening connect with buffler by the waters that exceedes stream pond or control of dust water tank, the inlet end that wherein makes mozzle is by bolt or welding or build by laying bricks or stones and be fixed on the inwall that exceedes stream pond or control of dust water tank, the other end is blocked by shrouding, promptly form a catheter type flow mixing device mutually by buffler and mozzle and inwall by body.In addition, the osculum on the corresponding clarifier is provided with drain tube in body.

In use, the flue tube of deduster body is connected with the supplied flue gases pipeline, an amount of water of input in exceeding stream pond or control of dust water tank.When operation, when decline constitutes the space with buffler after flue gas is walked around buffler upwards to erupt the water surface pressurized that makes its contact by flue impact downwards, mozzle will exceed the water in stream pond or the control of dust water tank, at any time introduce in the body and carry out comparatively fine and smooth mixed flow, thereby do not need to use water circulating pump and shower nozzle just can realize the mixed flow effect of flue gas and current from both-side opening outflow and flue gas; Through the mixed flow water-dust mixture of eruption upwards, be subjected to the effect of flow distribution plate to be subjected to the guide effect of centrifuge blade crack to form centrifugal motion again by aperture plate, and rotation is risen between centrifuge blade and louvre blade, therefrom make separated object and air carry out initial gross separation, because it is opposite with it that the guiding of louvre blade crack is set in the centrifuge blade periphery, the flue gas between rotates the impulsive force that forms that rises at a high speed can't flee from flue gas itself from the crack of louvre blade, opposite because the flue gas that rotation is risen by the louvre blade crack to around the jet action that produces of cold air it is sucked in expansion chamber, being inhaled into a large amount of cold airs mixes with the steam that is inclusive with flue dust, make it to drop on the intercepter plate very soon with the centrifugal motion that rotates ascending air after drop is formed in condensation with air separation, flow on the aperture plate to return through drain tube again and exceed stream pond or control of dust water tank by the body drain tube, and the air behind the process isolation of purified is subjected to the interior pressure effect of deduster body, continues to rise in expansion chamber and is discharged by discharge duct.

Promptly, can fundamentally remedy the deficiencies in the prior art, effectively improve the desulfurization dust-removing efficiency of deduster, reduce operating cost by the said goods structure provided by the invention and technical method.

Below in conjunction with accompanying drawing the present invention is described in further details

Accompanying drawing 1 is looked cutaway view for the master of product structure provided by the invention and its technical method embodiment

Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1
