Abstract

The utility model relates to a baffle type device for separating dispersed particles from gases or vapour, mainly composed of a box body and baffles. The box body is composed of a cover, a defogging box, an air inlet, an air outlet and a liquid storage box. The baffles are curved plates vertically arranged in the defogging box and curved along a vertical direction. The baffle type device for separating dispersed particles from gases or vapour makes use of curved channels containing gas or vapour flows and formed between the baffles to make liquid fog stick on the walls of the baffles through the actions of inertial force and centrifugal force so as to separate liquid drop from the gas and achieve the function for purifying the gas or vapour flows. The baffle type device for separating dispersed particles from gases or vapour has compact structure, small size, low cost and simple production and operation, particularly being suitable for purifying medium and small sized acid fog harming places.

Description

Baffle plate type mist clarifier

The utility model belongs to a kind of fog separator, particularly a kind of baffle plate type mist clarifier.

In order to improve worker's working condition, eliminate or reduce the acid mist harm healthy of generation in the production to the worker, must solve the purification treatment of acid mist in the production process.At present, all there is corresponding separately shortcoming in some main method of domestic improvement acid mist.Wherein, use more tower defogging equipment, as equipment such as packed tower, bubble-cap formula tower, rotating stream tray scrubbers, adopt alkali lye or water spray with in and acid mist, it is better that it removes fog effect, but it is big to handle air quantity, investment is many, and floor space is bigger, and is not too suitable to operation on a small scale; The electricity defogging equipment, the cost height, energy consumption is also high; Grid type mist treating apparatus, its cost is lower, and floor space is also little, but the net grid easily stop up, break, equipment cleans and the difficulty safeguarded is bigger; In addition, on electroplating industry, the defogging method that adopts acid fog inhibitor is arranged also, this method is easier, and cost is also lower.But the foam that inhibitor produces is bonded on the workpiece easily, makes surface of the work coarse, burnt hair, influences workpiece quality.

The purpose of this utility model is the shortcoming that overcomes above-mentioned mist clarifier, and provide a kind of baffle plate type mist clarifier, it has compact conformation, advantage that working resistance is little, is convenient to be attached in the device that produces mist, can the liquid burn-off be removed at the setting that produces fog as far as possible.

The purpose of this utility model is realized by following mode:

The utility model deflection plate mist clarifier mainly is made up of casing and deflection plate, and casing is formed by covering, remove fog chamber, air inlet, gas outlet and fluid storage tank, and deflection plate is the vertically crooked curved slab that vertically is placed on except that in the fog chamber.

The demist mechanism of this baffle plate type mist clarifier is to change airflow direction, by inertia force and high mental power function drop is separated from contain fog stream.Constituted passage between the crooked deflection plate, during through the corner, inertia force and centrifugal force impel droplet collision to the baffling wooden partition to the drop that contains fog stream with gas, and accumulation shape or liquid film flow down.Remaining drop through after channel cross-section redistributes, passes through for the second time, for the third time again ... baffling is built up, and contains drop in the fog stream and comes to this progressively separated from the gasly, makes the fog stream that contains through the mist clarifier no longer have drop.

The utility model has the advantages that: volume is little, compact conformation, and cost is low, and energy consumption is low, and manufacturing operation is simple, and working stability is reliable, and maintenance load is few, and good purification is particularly suitable for the purification work that middle-size and small-size acid mist endangers the place.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is that the utility model side is cutd open and shown structural representation.

Fig. 2 is the utility model plan structure cut-away view.

As shown in Figure 1 and Figure 2, this baffle plate type mist clarifier is made up of casing and deflection plate.Casing by lid 1, remove fog chamber 4, air inlet 3, gas outlet 10, fluid storage tank 7 and form.Lid 1 is placed on top except that fog chamber by clasp 2.Remove and vertically to place deflection plate 9 in the fog chamber 4, about respectively with air inlet 3, gas outlet 10 links to each other.The bottom of removing fog chamber 4 is a liquid reservoir 7.Except that interconnecting between fog chamber 4 and the liquid reservoir 7, firm for structure, remove between fog chamber 4 and the liquid reservoir 7 and be provided with supporting plate 5 and strutbeam 6.The bottom of liquid reservoir 7 is provided with leakage fluid dram 8.

Deflection plate 9 is the vertically crooked curved slabs that vertically are placed on except that in the fog chamber 4, and its shape also can be other curve form as shown in Figure 2.Being provided with storage 10 in deflection plate 9 curved surface knees, is for obtaining better separating effect.For air-flow is entered except that placing a latticed air-flow distributor 12 between air inlet 3 and deflection plate 9 more equably by whole baffle groups behind the fog chamber 4 from inlet air flow gas port 3.

Containing fog stream enters except that behind the fog chamber 4, by the bending channel that constitutes between the deflection plate from air inlet 3.Adhere on storage 10 and the baffling wooden partition at drop under inertia force and the action of centrifugal force, build up the formation liquid film and flow down.The deflection plate 9 that removes in the fog chamber 4 can be provided with some groups, and like this, containing fog stream can make drop more thoroughly separate with gas through repeatedly purifying.Drop accumulates in the liquid reservoir 7 after the baffling wooden partition flows down, by leakage fluid dram 8 with its discharge.
