Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
The purpose of the utility model is to provide a kind of wet-desulfurizing dust remover, to solve above-mentioned of the existing technology ask Topic, solves that existing flue gas desulfurization technique long flow path, control is complicated, plant area is big, investment is high, generates secondary pollution, needs The problems such as drain processing unit of special configuration.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have Body embodiment is described in further detail the utility model.
Wet-desulfurizing dust remover provided by the utility model as shown in Figure 1, main equipment by desulfurization washing tower 1 and first Circulating pump 2,3 composition of second circulation pump.Desulfurization washing tower 1 includes chill zone 4, uptake zone 5, filtering module dedusting area 6, mist eliminating zone 7 etc..
The middle lower end for the desulfurization washing tower 1 that chill zone 4 is horizontally mounted.Exhaust containing pollutant is in a horizontal manner from air inlet Mouth 17 passes through chill zone 4.The G400 spray head 8 for being mounted on chill zone 4 sprays circulation fluid, forms highdensity curtain of liquid, cigarette Air cooling reaches water saturation state.The direction and gas that liquid injection goes out flow to angled and extend to desulfurization washing tower 1 inner wall can rinse the inner wall of desulfurization washing tower 1 simultaneously.Spray liquid runs down into tower bottom along the inner wall of desulfurization washing tower 1, and desulfurization is washed The tower bottom for washing tower 1 is provided with taper liquid storage tank, realizes circulated sprinkling by first circulation pump 2.It is some while cooling gas Sulfur trioxide, sulfur dioxide and the biggish particle of partial size (being greater than 3 microns) are also removed.The pH-value of the loop slurry of spray is close It is neutral.
Uptake zone 5 is located at 1 middle section of desulfurization washing tower, and vertical direction equidistantly installs a row G400 spray head 8.G400 spray head 8 The loop slurry of ejection is used for sulfur dioxide absorption.When water saturated wet flue gas flows up through uptake zone 5 in tower, remaining two Sulfur oxide and biggish particulate matter are removed.Spray liquid runs down into the liquid storage tank of tower bottom along tower wall, is realized by first circulation pump 2 Circulated sprinkling.
Filtering module dedusting area 6 is mounted on the top of uptake zone 5.By one group of Venturi tube, 9, one groups of F130 spray heads 10 and one The slurry pool 11 of a taper forms.When flue gas passes through the Venturi tube 9 of filtering module dedusting area 6, flue gas first accelerates (compression) simultaneously After deceleration, 1~3 μm of dust particles and more tiny dust particles are contacted with the water in spray liquid, particle surface forms one layer Thin moisture film, entire partial size increase, it is easier to which the cascade sprayed by top F130 spray head 10 captures, and realizes flue gas ash removal, captures In the slurry pool 11 for falling on taper to the liquid of dust particles, circulated sprinkling is realized by second circulation pump 3.
The top of F130 spray head 10 is equipped with droplet separator 12, is in charge of by one group of hollow rotation and is formed, what each rotation was in charge of Static rotation fragment of the middle and upper part installation with angle.Flue gas is in charge of centre after desulfurization, dedusting, along desulfurization washing tower 1 and rotation Part, which is up to rotation, to be in charge of behind top 180 ° of directions of adjustment and is in charge of downlink from rotation, and flue gas passes through the work of centrifugal force through overwinding fragment With drop rotates and flows to tube wall.Collected water ceaselessly rinses the inner wall that rotation is in charge of, and flows in the weir of bottom end, then flows into Second circulation pumps 3 circulated sprinklings.
Chimney 13 is installed on 12 top of droplet separator of desulfurization washing tower 1, chimney 13 is arranged in the top of desulfurization washing tower 1 Portion acts on to guide and being discharged in atmosphere by flue gas.13 the top of chimney, gas keep low velocity in chimney 13, therefore, The water of condensation can flow back into tower without being brought in atmosphere.Before flue gas is discharged by the chimney 13 of desulfurization washing tower 1, cigarette Gas reinforces the collection of condensed water by a set of 13 tornadotron of chimney, reduces the white cigarette of 13 periphery of chimney of desulfurization washing tower 1 A possibility that plumage.
The utility model supplements water by water supplement port, realizes water balance by liquid outlet drain.High-temperature flue gas is made in spray Reaching water saturation state with the cooling of lower Quench, a part of liquid gasification is into flue gas, as purified flue gas is discharged into atmosphere, one Partial moisture loss;Loop slurry is added sodium hydroxide solution and is neutralized due to absorbing sulfur dioxide, forms sulfurous acid Sodium and sodium sulphate, salt content are constantly accumulated, and are needed to be discharged a part of loop slurry and are filled into fresh water, and salinity balance is maintained, Otherwise the excessively high precipitation of salinity causes pipeline and equipment scaling, blocking.
When the utility model wet-desulfurizing dust remover works, flue gas enters the chill zone 4 of desulfurization washing tower 1, hot fume It being come into full contact in the circulation fluid containing lye that chill zone 4 and G400 spray head 8 sprays, flue-gas temperature is down to saturation temperature, this The large-sized catalyst granules of process and a part of SO2Be absorbed, saturated flue gas after chill zone 4 on be advanced into SO2Absorption Area 5, this region arrange G400 spray head 8, and the circulation fluid that saturated flue gas is sprayed with spray head comes into full contact with, most SO2It is inhaling It receives area 5 to remove, saturated flue gas enters the removing of filtering module dedusting area 6 fine particle, the flue gas of saturation state after leaving uptake zone 5 Through herein filtering module effect first accelerate afterwards slow down, hypersaturated state is reached by adiabatic expansion, the water in flue gas is wrapped in On fine particle, the size of fine particle be increased dramatically, and the water sprayed by F130 spray head 10 captures, and be flushed to the leakage of filtering module In bucket.To guarantee that flue gas is free of drop into signs of human habitation chimney 13, into being provided with droplet separator 12 before chimney 13 for further By the water droplet removing in flue gas, saturated flue gas enters droplet separator 12, flue gas flow deflector in droplet separator 12 from above Under the action of change direction, the drop in flue gas is got rid of to wall under the action of the centrifugal force, is separated with gas.After separating drop Clean flue gas passes through the chimney 13 on top, is provided with chimney droplet separator at chimney 13 and further removes the drop in flue gas.
The circulation fluid PH in first circulation pump and second circulation pump in the utility model is controlled in 6.8-7 to SO2It inhales Fruit of producing effects is best, carries out supplement lye adjustment PH, therefore the utility model first circulation pump 2 is connected with liquid outlet 14 and inhales Agent adding mouth 15 is received, offers water supplement port 16 on 1 side wall of desulfurization washing tower.
Specific case is applied in the utility model to be expounded the principles of the present invention and embodiment, it is above The explanation of embodiment is merely used to help understand the method and its core concept of the utility model;Meanwhile for the one of this field As technical staff, based on the idea of the present invention, there will be changes in the specific implementation manner and application range.To sum up Described, the content of the present specification should not be construed as a limitation of the present invention.
