Detailed description of the invention
Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be elaborated.
As shown in Figure 1, for the erect type multi-parallel flat plate type washing tower 10 that the present invention's the first preferred embodiment provides, it includes a tower body 20, multiple dull and stereotyped 30, water supply part 40, a demister 50, a cleaning solution supply line 56, a medicament storage tank 58, detecting pipeline 60 and a scavenger fan 62.
The inner hollow of tower body 20 is formed with a reaction chamber 22, an air inlet 23, an exhaust outlet 24 and a cleaning solution storage tank 25, air inlet 23 and exhaust outlet 24 are all communicated with reaction chamber 22, cleaning solution storage tank 25 is positioned at reaction chamber 22 belows, be used for storing cleaning solution 251, tower body bottom side also has an osculum 26, to unnecessary cleaning solution 251 is discharged.
As shown in Figure 1 to Figure 3, each dull and stereotyped 30 is uprightly and to be in parallel to each other located in the reaction chamber 22 of tower body 20, the interior sidewall surface of tower body 20 is formed with multiple caulking grooves 29, is embedded at wherein for each edge of dull and stereotyped 30, between any two adjacent many parallel flats 30, is all formed with a gap 32.In the present embodiment, each dull and stereotyped 30 is the plastic plate (as polypropylene board) through sandblast roughening, and matching surface pickling processes, the processing of electricity slurry and titanium dioxide (TiO 2) or silica (SiO 2) coating of nanogel, make its both side surface all can form Superhydrophilic surface, make cleaning solution form uniform water film in its surface easily.Each dull and stereotyped 30 also can replace with the glass plate through surface sand-blasting processing.
Water supply part 40 is arranged in the reaction chamber 22 of tower body 20, and is positioned at each dull and stereotyped 30 tops, and includes a body 42 and three sprayers 44, and each sprayer 44 is located at body 42, and can spray cleaning solution towards each dull and stereotyped 30.
As shown in Fig. 1 and Fig. 4, demister 50 is located at tower body 20 inside, and between exhaust outlet 24 and each dull and stereotyped 30, demister 50 includes multiple wavy fins 52, and each fin 52 both sides are provided with the horizontal portion 54 of stretching that multiple cross sections are L font, for tackling water smoke.
Again as shown in Figure 1, cleaning solution supply line 56 is to connect respectively the body 42 of water supply part 40 and the cleaning solution storage tank 25 of tower body 20 with its two ends, by the action of pump 561, the cleaning solution 251 in storage tank 25 can be transported to sprayer 44 through cleaning solution supply line 56 and body 42 and spray.
Medicament storage tank 58 is connected with cleaning solution supply line 56 through a dosing pipe 581, in the time that the contained concentration of absorbing of cleaning solution in cleaning solution storage tank 25 is too low, by the action of pump 583, the medicament of medicament storage tank 58 inside just can be added among cleaning solution through dosing pipe 581.
Detecting pipeline 60 is the cleaning solution storage tanks 25 that connect respectively cleaning solution supply line 56 and tower body 20 with its two ends, thus, a part of cleaning solution in cleaning solution supply line 56 can flow back to cleaning solution storage tank 25 through detecting pipeline 60, on detecting pipeline 60, a pH meter 601 and a conductoscope 603 are also set, operator can grasp the opportunity of adding medicament by both monitoring numerical value.
Scavenger fan 62 connects the exhaust outlet 24 of tower body 20, and can be to tower body 20 internal air exhaustings.
Via said structure, the sprayer 44 of water supply part 40 can spray cleaning solutions towards each dull and stereotyped 30, and cleaning solution can be flowed downward via the gap of each dull and stereotyped 30 and to form the mode of moisture film, flows back to subsequently cleaning solution storage tank 25 and is recycled.Under the effect of scavenger fan 62, pending waste gas can enter reaction chamber 22 via the air inlet of tower body 20 23, and upwards flow by the gap 32 of each dull and stereotyped 30, now, the uniform water film that cleaning solution forms just can effectively absorb the vaporous and particulate contaminant in waste gas, reach the object of purification, purified gas is follow-up will tackle unnecessary cleaning solution by demister 50, then is disposed to the external world via exhaust outlet 24.
Utilize surface treatment method to improve its hydrophily due to each dull and stereotyped 30, therefore cleaning solution all can form uniform water film in its both side surface, contributes to promote contaminant removal efficiency.In addition, all be tabular due to each dull and stereotyped 30, the flow path of waste gas in reaction chamber 22 is simple, the holdup time of waste gas can be grasped more easily, therefore, operator can be controlled at an optimum range by the holdup time that waste gas is trapped in to each dull and stereotyped 30, for example, be controlled between 0.25 to 1.0 second, improves the removal efficiency of pollutant; Moreover designer also can adjust according to the air quantity of pending waste gas the width in the gap 32 of dull and stereotyped 30, and the holdup time of gas pollutant is controlled in above-mentioned optimum range.
According to creation spirit of the present invention, erect type multi-parallel flat plate type washing tower structurally also has multiple variation, again as shown in Figure 5, the erect type multi-parallel flat plate type washing tower 70 providing for the present invention's the second preferred embodiment, the structure of itself and previous embodiment is roughly the same, its difference is, erect type multi-parallel flat plate type washing tower 70 has two water supply parts 73 and two cleaning solution supply lines 75, two water supply parts 73 are arranged at respectively tower body 71 both sides, it is respectively an overflow launder, and be respectively connected with cleaning solution storage tank 714 by a cleaning solution supply line 75, the washings of the flat scrubbing tower 70 of this embodiment are to utilize the mode of overflow to enter reaction chamber 712.
The above; be only detailed description and the diagram of preferred embodiment of the present invention; the embodiment of all spirit variations similar with it that meets the claims in the present invention; in this area any be familiar with that this skill person can think easily and variation or modification, all can be encompassed in scope of patent protection of the present invention.
