Abstract

The utility model relates to a desulfurizing dust remover which separates dust from smoke gas and eliminates the harmful gas of SO<2>, etc. The upper part is provided with an air inlet pipe whose transition section is bent for 90 DEG. A hollow throat and a water spraying device are arranged on the air inlet pipe. The lower part of the air inlet pipe is provided with an adsorption chamber, and a fine dust separating chamber is arranged side by side with the adsorption chamber. The upper part of the fine dust separating chamber is provided with a desulfurizer, and a plurality of blocks of Z-shaped folded plates are arranged in the desulfurizer. The desulfurizing dust remover of the utility model is designed and formed by the utilization of a plurality of dust removing principles. Besides the efficacy of dust removing, desulfurization, denitrogenation, etc., the utility model also has the characteristics of compact structure, easy operation and adaptability.

Description

Novel desulfurizing dust-collector

The utility model belongs to dedusting, isolation technics, mainly proposes a kind of novel desulfurizing dust-collector.

At present, the deduster kind that is used for environment-friendly engineering is a lot, and common deduster has following several: 1, decanter type deduster, it is bulky, only the dirt powder of grit greater than 50 μ m is just produced effect.2, cyclone dust collectors, its efficient is lower, and is easy to wear.3, gravel bed filter, resistance is big, and the energy consumption height is unsuitable for the big gas of water capacity.4, filter bag type deduster, its cost height, filter bag is fragile.5, water film type duster, it is bulky, and efficiency of dust collection is about 90%.6, electric cleaner, its cost height, Operation and Maintenance requires high.

The purpose of this utility model promptly is the efficiency of dust collection height is provided, and volume is little, can remove the SO in the flue gas again ₂, NO ₂Novel desulfurizing dust-collector Deng pernicious gas.

The utility model is finished the technical scheme that its invention task taked: the top is provided with blast pipe, and its changeover portion is 90 ° and is bent downwardly, and the reclinate pipeline section of blast pipe is provided with further the fully trunnion of mixed flue gas and atomization flow; Between reclinate pipeline section of air inlet pipe and trunnion, water injector is housed.

The blast pipe bottom is provided with adsorption chamber, in the S shape bent plate that polylith equates at interval is housed; Be arranged side by side the fine dust separation chamber with adsorption chamber, polylith S shape bent plate is housed in it, adsorption chamber and bottom, fine dust separation chamber communicate with storage tank.

Top, fine dust separation chamber is provided with moisture eliminator, and the Z-shaped flap of polylith is housed in it.

Desulfurizing dust-collector of the present utility model utilizes multiple dust-cleaning principle to design, and also has compact conformation except that having effects such as dedusting, desulfurization removing nitric, implements easily, and characteristics such as wide adaptability have tangible environmental benefit.

The embodiment that provides is in conjunction with the accompanying drawings further specified its structure:

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A cross section view among Fig. 1.

Fig. 3 is the front view of S shape bent plate.

Fig. 4 is the side view of S shape bent plate.

Fig. 5 is the front view of the inner water fender of moisture eliminator.

Fig. 6 is the inner water fender side view of moisture eliminator.

As shown in drawings: mainly include blast pipe 1, sparge pipe 2, trunnion part 3, adsorption chamber 4, storage tank 5, fine dust separation chamber 7, moisture eliminator 8, discharge pipe 9.Top of the present utility model is provided with a blast pipe 1, its inducer is in level substantially, its changeover portion is 90 ° and is bent downwardly, the flue gas level is introduced, then vertically downward, when flue gas is flowed through this pipeline section under gravity, inertia force, action of centrifugal force big dust particle from flue gas, separate, drop down along tube wall, stainless steel tube and eight water injectors 2 that the stainless steel nozzle is formed of internal diameter 25mm are housed between blast pipe 1 reclinate pipeline section and trunnion part 3, make 2～4Kgf/cm of ejection ²Press water atomizing, the aditus laryngis of trunnion part is major axis 400mm, the ellipse of minor axis 150mm.The flue gas flow at high speed further atomizes water, thereby makes the fine dust in the flue gas moistening, and running foul of each other is condensed into the dust of larger particles, separates from flue gas at an easy rate.Flue gas enters adsorption chamber 4 with water, 5 block length 600mm are housed in the adsorption chamber, wide 800mm, the S shape bent plate of thick 5mm, interval 100mm between every block of plate, the water of atomizing form multiple tracks moisture film on its surface is adhered under the capture dust, flue gas enters storage tank 5 downward vertically, the sewage pipe 6 of diameter 100mm is housed on the storage tank 5, and sewage is constantly discharged outside the deduster through this pipe, flows to sedimentation basin.Flue gas through after turning to 180 ° behind the storage tank 5 from newly upwards entering fine dust separation chamber 7, fine dust separation chamber 7 its sectional area ratio adsorption chambers 4 are much bigger, the inside is equipped with many interval 200mm, long 800mm, wide 800mm, the S shape bent plate of thick 5mm, flow velocity reduced greatly when flue gas was flowed through S shape bent plate, fine dusts and water droplet in the flue gas further condense, and under the effect of power such as centrifugal force and surface tension, fine dusts and the cohesion of little water droplet are adsorbed on the S shape bent plate.Along with drop increases, last gravity slides along S shape plate during greater than its adhesive force and enters 5 li of storage tanks.The flue gas moisture eliminator 8 of then flowing through, moisture eliminator is the square box of long 800mm, wide 500mm, high 500mm, many long 800mm are equipped with in the inside, and the Z-shaped flap of thick 5mm is further removed the little water droplet in the flue gas, little dust through effects such as collision, absorption when flue gas flows through.Flue gas is arranged to chimney under the effect of discharge pipe 9 at air-introduced machine, and then enters in the atmosphere.When needs remove SO ₂, NO ₂When the pernicious gas, can in sedimentation basin, add alkaline matter to neutralize, make liquid show alkalescence and spray in the deduster by water circulating pump (water injector), so just make flue gas obtain purification, protected environment.

The utility model the experiment proved that its efficiency of dust collection is up to 99.5%, and desulfurization degree is more than 85%.
