Abstract

The utility model relates to an effective dust-removing sweetening apparatus which can be used for the sweetening and dusting removing of the boiler flue gas and also for the sweetening technology construction of the prior granite water membrane dust collector. The middle of a main cylinder is equipped with a rotating-stream plate to strengthen gas-liquid mixing contact, the upper part is equipped with an annular water retaining edge and a water retaining slot, and the top is provided with a sweetening absorption liquid atomizing nozzle; the middle of an auxiliary cylinder is equipped with a demisting dehydration rotating-stream plate, the lower part is provided with a dehydration sleeve for ensuring gas-liquid shunting and a hydration exhaust pipe. The utility model can achieve the functional requirement of effective dust-removing and sweetening using smaller investment and simplified structure, and is in particular applicable to the sweetening technology construction of the prior granite water membrane dust collector.

Description

A kind of pair of plate dust removal with desulfurization by water film device
The utility model belongs to the fire coal boiler fume dust-removing desulfurating apparatus, is applicable to the efficient desulfurizing and dust collecting of Industrial Boiler and station boiler.
At present, in coal-burned industrial boiler and station boiler, quite a few is equipped with the granite water dust scrubber, its operation principle is that the flue gas of the sulfur dioxide that will get rid of in the combustion apparatus is by a Venturi tube, tangentially enter water dust scrubber (claiming " main tube " or " drop catcher " again), main tube top is provided with the spilling water groove, forms the dirty moisture film of inwall thereby recirculated water is introduced water jacket in the inside groove overflow, cleans the dust in flue gas of bottom-up weak tendency rotational flow.Because the gas-liquid contact is insufficient, efficiency of dust collection generally is lower than 90%, and does not have desulfurizing function substantially, can not satisfy the environmental protection requirement of increasingly stringent.Some improvement in recent years is to set up 3~4 grades of eddy flow plates in a main inside, and the discharge opeing of eddy flow plate takes fan type overfall to concentrate distribution again, and this kind mode can be raised the efficiency, but it is many to consume material, and complexity is installed, and resistance also has bigger increase.
The purpose of this utility model is the deficiency that exists at the existing and above-mentioned dust removal with desulfurization by water film device that has improved, a kind of new easy structure is provided, in not bigger change original granite water dust scrubber external structure and do not roll up under the situation of equipment investment, integrate the dust-removal and desulfurizing technology, neither excessively increase SR, can improve dust-removal and desulfurizing efficient greatly again.The technical scheme that the utility model proposes both can be applicable as novel product, also can be as the desulfur technology transformation of traditional granite water dust scrubber.
The technical solution of the utility model is made up of with liquid distributor, secondary tube Venturi tube, main tube.The eddy flow plate is established at main tube middle part, and top is 90 ° of spray water distribution film devices, and one evagination right angled triangle dash edge and three road chamfer triangle indent water-blocking grooves have been done in its top, and the desulfurization atomizer is arranged at a main tube top; Establish demist dehydration eddy flow plate at secondary tube middle part by airflow direction, the bottom is the dehydration sleeve, connects air outlet in the middle of the dehydration sleeve, and the dehydration delivery pipe is established in the bottom.
As shown in the figure, figure one: (1) air intake Venturi tube; (2) main tube; (3) current stabilization post; (4) eddy flow plate; (5) water distribution film ring pipe; (6) cloth moisture film nozzle; (7) dash edge; (8) water-blocking groove; (9) desulfurization atomizer; (10) secondary tube; (11) demist dehydration eddy flow plate; (12) dehydration sleeve; (13) dehydration delivery pipe.
Figure two: (6) 90 ° of spray cloth moisture film nozzles.
Below in conjunction with the description of drawings preferred forms:
The flue gas of discharging from combustion apparatus tangentially enters main tube (2) bottom through air intake Venturi tube (1) and does around current stabilization post (3) and rotate up motion, a plurality of 90 ° of cloth moisture film nozzles (6) that the top of main tube is introduced by water distribution film ring pipe (5) form downward adherent current at internal face, contact with flue gas from bottom to top, the grit of trend barrel in the rotation flue gas is cleaned, if ejection liquid contains alkaline medium, then sulfur in smoke and liquid film also can haptoreactions, generate sulphite and sulfate solid particle.The eddy flow plate (4) of main tube middle part installing has played outstanding invigoration effect just in gas, liquid, solid three-phase mass transport process.Because eddy flow plate cover tube and inwall keep suitable distance, whole moisture film is not destroyed in the circular passage of formation, thereby has formed the reasonable diffluence of gas-liquid when strengthening the gas-liquid contact.The dash on cloth moisture film nozzle (6) top can stop liquid to flow to the rear portion along (7) and water-blocking groove (8) to carry secretly effectively.The atomizer (9) that install at the top can be introduced the higher desulfurization absorption liquid of pH value, further improves desulfuration efficiency.Enter the flue gas of secondary tube (10), be forced to separate at middle part demist dehydration eddy flow plate (11) in lasting gas-liquid mixed reaction back, the water smoke drop that concentrates is thrown to barrel and is formed downward cascading water, the not disturbed bottom that flow to is discharged by the dehydration delivery pipe (13) of sealing state in dehydration sleeve (12) and the slit of internal face.
The utility model compared with prior art collects dust-removal and desulfurizing in a device, All establish spiral board in main tube, secondary tube, strengthen gas, liquid, solid and mix contact, improved and removed Dirt, desulfuration efficiency; Strengthen simultaneously gas-liquid separation, effectively reduce the water capacity of outlet flue gas, Guarantee system operation reliability. For the higher occasion of dust-removal and desulfurizing performance requirement, also can To set up again the one-level spiral board at main tube, secondary tube.
On existing Water film dust remover of granite basis, set up the one-level spiral board at main tube, Install the atomizer of absorption liquid additional; Set up the one-level spiral board at secondary tube, the bottom installs dehydration additional Sleeve and delivery pipe can improve dedusting, desulfuration efficiency significantly, finish desulfur technology Transform.
