Technical background
Dioxide peroxide is a kind of strong oxidizer, and stable dioxide peroxide is thought effective sterilant and excellent property, the good disinfection sanitizer of effect by the World Health Organization, is widely used in the bleachery of pulp mill.Current China has realized the production domesticization of small-sized sterilization chlorine dioxide production equipment, but, for the large-scale chlorine dioxide preparation system that in situ preparation and onsite application digest, domesticly also be in the starting stage, the large-scale chlorine dioxide production system that newly-built papermaking enterprise adopts starts to adopt domestic suite of equipment technology.
The main application of dioxide peroxide is association with pulp bleaching and drinking water disinfection, and dioxide peroxide has high whiteness for association with pulp bleaching, whiteness is stablized, keep intensity and the hypotoxic feature of the low color of draining, and its advantage is that other chemical any is incomparable so far.In view of the high toxicity of ClO 2 bleaching superiority and bleaching by chlorine gas, National Development and Reform Committee has recommended dioxide peroxide to be one of chemical of association with pulp bleaching, and progressively eliminates bleaching by chlorine gas technique.
Synthetic method process of preparing chlorine dioxide comprises sodium chlorate and mixed in hydrochloric acid, and wherein hydrochloric acid is not only as reductive agent but also as the acidic medium of reaction, reaction formula is:
NaClO
3+2HCl→ClO
2+1/2Cl
2+H
2O+NaCl
In production process, from the strong sodium chlorate solution (sodium chlorate 520g/L, sodium-chlor are 108g/L) of sodium chlorate reactor and the hydrochloric acid of concentration 32% pass into by a certain percentage dioxide peroxide vacuum generator carry out sending out should, produce the mixed gas of dioxide peroxide and chlorine.The concentration of hydrochloric acid added is higher, even if be also easily corroded with titanium pipe.Therefore, manufacture a kind of hydrochloric acid being applicable to synthetic method chlorine dioxide preparation system production environment to add pipe and become common recognition.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hydrochloric acid being applied to synthetic method chlorine dioxide preparation system and adds compound tube, to improve the work-ing life that hydrochloric acid adds pipeline.
The utility model solves the problems of the technologies described above with following technical scheme:
The hydrochloric acid that the utility model is used for synthetic method chlorine dioxide preparation system adds compound tube, this compound tube by be responsible for 3 and hydrochloric acid injection tube 4 form, hydrochloric acid injection tube 4 is connected communicates with supervisor 3, the axis of hydrochloric acid injection tube 4 is mutually vertical with the axis of supervisor 3, supervisor's tube wall of 3 and the tube wall of hydrochloric acid injection tube 4 are made by 3 layers of different material, wherein internal layer is PTFE material layer, and middle layer is enamel material layer, and pipe outer wall is carbon steel material layer.
The hydrochloric acid that the utility model is used for synthetic method chlorine dioxide preparation system adds compound tube, and described hydrochloric acid injection tube 4 has 2, and position is near the reaction solution entrance end of supervisor 3, and 2 hydrochloric acid injection tubes 4 distribute relative to the axisymmetrical of supervisor 3.
The utility model, according to the characteristic of the reaction solution in reactive system and hydrochloric acid, is selected 3 kinds of different materials to constitute the hydrochloric acid being applicable to synthetic method chlorine dioxide preparation system and is added compound tube, preferably resolve the etching problem that concentrated hydrochloric acid adds pipe.
Accompanying drawing explanation
Fig. 1 is that the utility model hydrochloric acid adds the installation site of compound tube in reactive system.
Fig. 2 is the enlarged diagram that the utility model synthetic method chlorine dioxide preparation system hydrochloric acid adds compound tube.
Fig. 3 is I portion enlarged diagram in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the reactive system that prepared by synthetic method dioxide peroxide is added compound tube 3, upper circular tube 5, producer 8 and lower circulation tube 9 be composed in series by recycle pump 1, reboiler 2, hydrochloric acid.Hydrochloric acid adds compound tube 3 and is provided with 2 hydrochloric acid injection tubes 4; Producer 8 is provided with Explosion-proof cap 6 and dioxide peroxide venting port 7; Lower circulation tube 9 is provided with sodium chlorate solution and adds entrance 10.
Described hydrochloric acid adds the structure of compound tube 3 as shown in Figures 2 and 3, it by be responsible for 3 and hydrochloric acid injection tube 4 form.Hydrochloric acid injection tube 4 has 2, and position is near the reaction solution entrance end of supervisor 3, and the axis of hydrochloric acid injection tube 4 and the axes normal of supervisor 3,2 hydrochloric acid injection tubes 4 distribute relative to the axisymmetrical of supervisor 3.
The tube wall of described supervisor 3 is made up of 3 layers of different combination of materials, and be that the material of the internal layer 13 contacted with reaction solution is PTFE material respectively, middle layer 12 material is enamel material, and the material of pipe outer wall 11 is carbon steel materials.
The tube wall of described hydrochloric acid injection tube 4 is also formed by 3 layers of different combination of materials, be the material of the internal layer 16 contacted with hydrochloric acid are respectively PTFE material, the material in middle layer 15 is enamel materials, and the material of pipe outer wall 14 is carbon steel materials, and the material stretching into the nozzle 17 in supervisor 3 is Ti.
During work, raw material sodium chlorate charging pump is extracted out from feeding trough, after supercooler, strainer, add entrance 10 from the sodium chlorate of lower circulation tube 9 enter into generator system; The hydrochloric acid of 32% is also delivered to hydrochloric acid injection tube 4 with charging pump and is added producer; Start recycle pump 1, under the effect of recycle pump 1, raw material NaClO
3enter reboiler 2, and enter in generator main body 8 after mixed in hydrochloric acid, the ClO of generation
2discharge.The remaining liquid of reaction sinks to bottom producer, and become producer reaction solution, reaction solution constantly circulates under the effect of recycle pump 1 between reboiler 2 and producer 8, and with the NaClO constantly added
3solution, mixed in hydrochloric acid, reaction, constantly generate ClO
2gas.The ClO generated in producer
2gas by the steam dilution be evaporated in a large number, becomes mixed gas in producer, and mixed gas enters inter cooler cooling, then enters absorption tower refrigerated water and absorb, become ClO after flowing out from the venting port 7 at producer top
2the aqueous solution.
In working process, the supervisor 3 that hydrochloric acid adds compound tube is PTFE with the material of reaction solution contact part, resistance to reaction solution corrosion; 2 hydrochloric acid injection tubes 4 are also Ti and PTFE with the material of concentration 32% hydrochloric acid contact part, the corrosion of resistance to concentration 32% hydrochloric acid, thus preferably resolve the etching problem that concentrated hydrochloric acid adds pipe.
