Enter the ClO of chlorine dioxide absorption tower
2in mist, contain ClO
2, Cl
2, H
2the multiple gases such as O, can dodge quick-fried accident while reaching finite concentration in tower.Therefore,, by the transformation of chlorine dioxide absorption plant and optimization, guarantee that production system safe operation has become common recognition.
Utility model content
Technical problem to be solved in the utility model is to provide the chlorine dioxide absorption plant with maltilevel security safeguard measure that a kind of applicable synthesis chlorine dioxide preparation system is used.
The utility model solves the problems of the technologies described above with following technical scheme:
The utlity model has the chlorine dioxide absorption plant of multi-level safety safeguard measure, comprise absorption tower, tower body middle part, absorption tower is provided with packing area, tower body top is provided with the liquid distributor being connected with shower, tower body bottom connects chlorine dioxide mist input pipe, tower body top is provided with gas outlet tube, tower body bottom is provided with chlorine dioxide pump groove, the external chilled water house steward of shower, chilled water transfer pump, chilled water head tank and emergent fire extinguisher canvas hose access chilled water house steward after pipeline formation is connected in parallel; Tower body bottom arranges the venting that explosion-proof diaphragm is housed; On the pipeline of connection chilled water head tank outlet and emergent fire extinguisher canvas hose, be respectively equipped with controller.
The utlity model has the chlorine dioxide absorption plant of multi-level safety safeguard measure, described gas outlet tube connecting fan, delivers to HCl synthesis unit by blower fan by the weak chlorine mist of major part, and the weak chlorine mist of part is delivered to hypo tower and processed.
The utlity model has the chlorine dioxide absorption plant of multi-level safety safeguard measure, described chlorine dioxide pump groove is connected with chlorine dioxide delivery pump through pipeline, the output of chlorine dioxide delivery pump divides two-way, and a road connects chlorine dioxide storage tank through pipeline, and another road is in pipeline is connected to tower body; The pipeline that connects chlorine dioxide storage tank is provided with controller.
The utility model device can better guarantee the safe operation of chlorine dioxide preparation system under normality and unregulated power supply condition, compared with prior art, has following beneficial effect:
1. the venting of explosion-proof diaphragm is equipped with in the setting of the utility model chlorine dioxide absorption plant, can prevent that the aqueous solution of chlorine dioxide decomposition in tower from causing the too high generation blast of tower internal pressure;
2. the chilled water that tower top is carried by chilled water transfer pump, the chilled water of head tank and emergent fire water converge into a pipe after by pipeline parallel connection and enter spray head, in tower, spray liquid.In process of production, if power-off suddenly, the reactant liquor in generator is also continuing to produce chlorine dioxide mist, and chilled water pump is because carrying chilled water without electricity supply.Now, the chilled water of chilled water head tank is just carried in absorption tower, forms ground floor safeguard protection; If the freezing water yield in chilled water head tank is also not enough to guarantee to keep the safety in production, fire extinguisher canvas hose will supply water in tower, has formed second layer safety precautions.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utlity model has the chlorine dioxide absorption plant of maltilevel security safeguard measure.
The specific embodiment
As shown in Figure 1, the utility model chlorine dioxide absorption plant, mainly fills Packed chlorine dioxide absorption tower tower body 20, chlorine dioxide pump groove 2, chilled water head tank 12, chlorine dioxide delivery pump 4, blower fan 17 and related process pipeline by middle part and forms.The top of chlorine dioxide absorption tower tower body 20 is provided with liquid shower 18 and liquid distributor 19, and the outlet of liquid shower 18 connects liquid distributor 19, the external chilled water house steward 15 of entrance; Tower body middle part is to fill Packed gas-liquid mixed uptake zone; Tower body bottom is provided with chlorine dioxide mist input pipe 1 and the venting 8 that explosion-proof diaphragm is housed is set; Tower body bottom connects chlorine dioxide pump groove 2, chlorine dioxide pump groove 2 is connected with chlorine dioxide delivery pump 4 through pipeline 3, the output of chlorine dioxide delivery pump 4 divides two-way, one tunnel output connects storage tank through pipeline 5, and controller 6 is installed on pipeline 5, another road output is connected to the top of tower body chlorine dioxide pump groove 2 through pipeline 7, most of aqueous solution of chlorine dioxide is delivered to chlorine dioxide storage tank feed flow through pipeline 5, and small part aqueous solution of chlorine dioxide is back in tower body through pipeline 7; Gas outlet tube 16 is arranged at tower body top, gas outlet tube 16 is connected with blower fan 17, and blower fan 17 is delivered to HCl synthesis unit by the weak chlorine mist of major part, and the weak chlorine gaseous mixture of part is delivered to hypo tower and processed, keep negative pressure in tower simultaneously, be beneficial to chlorine dioxide gaseous mixture and rise smoothly; The chilled water of being carried by chilled water transfer pump 11, chilled water head tank 12 converge to chilled water house steward 15 again to shower 18 feed flows through pipeline through the chilled water of pipeline 14 outputs and the water of being carried by emergent fire extinguisher canvas hose 10.
