Description
Technical field
The utility model relates to a kind of emission-control equipment, particularly relates to a kind of flue gas of containing harmful components of making and mixes with vaporific absorption liquid, thereby improve harmful components to remove efficient be the gas-liquid mixed absorption tower of purpose by improving reaction efficiency.
Background technology
The gas-liquid mixed absorption tower is to remove the harmful components such as dust, sulfur dioxide and nitrogen oxide that contain in the flue gas and be arranged on equipment in the discharge duct for reaching.It mixes with vaporific absorption liquid by making harmful components, chemical reaction takes place and reaches the purpose of removing harmful components.Original gas-liquid mixed absorption tower causes removal efficient lower because the reaction efficiency of flue gas and absorption liquid is lower, in order to improve removal efficient, the manufacturing volume ratio on general gas-liquid mixed absorption tower is bigger, and this becomes a major defect of original technology.
In order to overcome the deficiency of prior art equipment, spiral helicine baffle plate is set in inside, absorption tower.Nozzle is atomized spray to inside, absorption tower with absorption liquid, and flue gas that utilizes the helical form baffle plate allow to contain pernicious gas and vaporific absorption liquid rotate in cylindrical shell, make it fully mix contact, reaches the effect of removing pernicious gas by chemical reaction.But atomizer sprays into absorption liquid with vaporific form, in the process that flows downward along the helical form baffle plate, progressively accumulates into water droplet, makes the contact area of absorption liquid and flue gas reduce, and causes reaction efficiency lower.
Another method is in the inside on absorption tower cyclone to be set, but the hydrocyclone structure complexity, fouling easily, and desulfuration efficiency reduces with the tower diameter increase; Some device needs to adopt the mode of tangential admission, and the center forms the poor efficiency district easily; In addition, cyclone is set, has improved equipment cost inevitably.
Summary of the invention
Technology art problem to be solved in the utility model provides a kind of high gas speed emission-control equipment, overcome the problem that existing equipment exists, the abundant contact that makes the gas-liquid of inside, gas-liquid mixed absorption tower not have the dead angle mixes, prevent reducing of absorption liquid and flue gas contact area, improve flue gas and vaporific absorption liquid contact probability, thereby reach the efficient purpose of handling in than short contacting time, improved gas speed, reduced gas-liquid mixed absorption tower volume.
The utility model adopts following technical scheme to realize:
This device includes gas-liquid mixed absorption tower, atomizer, baffle plate, absorption liquid circulatory pool, absorption liquid circulating pump and demister, the gas-liquid mixed absorption tower is vertically disposed cylindrical tube, adopt the mode of following current, smoke inlet is positioned at the cylindrical shell upper end, exhanst gas outlet is positioned at the cylindrical shell lower end, and smoke inlet and exhanst gas outlet are connected in the flue.Atomizer is arranged on the top of cylindrical shell, and central interior is goed deep into from the side of cylindrical shell in the below of smoke inlet, and its front end is crooked setting downwards.Baffle plate is arranged on the inwall of cylindrical shell, and it is made by sieve tray.The baffle plate layering is laid, and the baffle plate on every layer along the circumferential direction evenly distributes, layer with layer between baffle plate be staggered.Baffle plate is along the circumferential direction downward-sloping, to central interior certain angle of inclination is arranged also simultaneously.
Atomizer has the ability that vaporific absorption liquid can be sprayed onto equably the All Ranges of cylindrical shell.Atomizer is connected with the absorption liquid circulatory pool, and the absorption liquid circulating pump is transported to atomizer with absorption liquid from the absorption liquid circulatory pool, by atomizer absorption liquid is vaporific again and sprays in the cylindrical shell.
Baffle plate is to 0.3～1.0 of cylindrical shell central length from barrel to the center direction extension elongation.The segmentation rate of the circumferencial direction of a slice baffle plate accounts for 1/4～1/8 of full girth, promptly from the cylindrical shell top, can see 4～8 main wings, and whole baffle plates constitutes a full circle from overlooking.Relative circumferencial direction inclination 20～60 degree of baffle plate.Simultaneously, flow to central interior again in order to make under centrifugal action the vaporific absorption liquid to the inwall diffusion of cylindrical shell, reach and prevent that vaporific absorption liquid is condensed into the purpose of water droplet in the cylinder inboard wall process of flowing, each baffle plate is central authorities' 0～30 degree that tilts relatively.Baffle plate is made by sieve tray, on open the sieve aperture of diameter 5～20mm, the sieve aperture gross area accounts for 20～50% of baffle plate area.Because the downward rotational flow of vaporific absorption liquid is subjected to stopping of baffle plate, the vaporific absorption liquid in flowing can become water droplet at the surface aggregation of main wing, and the effect of sieve aperture is to prevent to form the generation that water droplet reduces gas-liquid mixed efficient situation.
Effect of the present utility model and benefit are:
Because the inner baffle plate that is provided with in the utility model gas-liquid mixed absorption tower makes gas that turbulent flow take place, improve flue gas and vaporific absorption liquid contact probability, can in than short contacting time, reach the purpose of efficient processing, thereby improve gas speed, reduce gas-liquid mixed absorption tower volume; This gas-liquid mixed absorption tower gas scooter is to 10m/s.
Baffle plate has certain gradient to central interior, and the vaporific absorption liquid to the diffusion of absorption tower inwall is flowed to central interior again, reaches to prevent that vaporific absorption liquid is along the purpose that is condensed into water droplet in the cylinder inboard wall process of flowing.
The baffle plate of being made by sieve tray has prevented that effectively vaporific absorption liquid is rotated down in the flow process in baffle surface gathering formation water droplet, the efficient of maintenance gas-liquid mixed.
