Description
Technical field
The utility model relates to chlorine dioxide washing technology field, is specifically related to the wash mill of residual chlorine dioxide in a kind of pulp production.
Background technology
Chlorine dioxide is known as safety, nontoxic green disinfectant in the world, for bleaching in pulp production, but use the enterprise of chlorine dioxide to throw in roughly chlorine dioxide according to knowhow, there is no scientific algorithm, cause and often have chlorine dioxide residue in the middle of drift slurry process, thus cause the corrosion of subsequent processing, if carry out anticorrosion transformation to the equipment of subsequent processing simultaneously, its investment is huge, enterprise is difficult to bear, and this situation also causes chlorine dioxide to be difficult to promote in paper pulp papermaking industry.
Summary of the invention
The purpose of this utility model is that providing one can realize chlorine dioxide washing throws in detection integrated full-automatic process, and the chlorine dioxide wash mill that the use cost that works is low.
For achieving the above object, the utility model provides following technical scheme:
The wash mill of residual chlorine dioxide in a kind of pulp production, comprise reservoir, precision metering pump, control instrument, blender, reaction tube and sensor, reservoir is built with sodium thiosulfate, reservoir connects precision metering pump input port, precision metering pump is provided with external control data wire, external control data wire connection control instrument, precision metering pump delivery outlet connects blender, the pulp solution of blender input port input containing chlorine dioxide residue, blender delivery outlet is connected to reaction tube input port, reaction tube rear end connecting sensor, sensor connection control instrument, reaction tube delivery outlet connects wash engine.
As the further improvement of above-mentioned technology, oxidation-reduction potential sensor selected by described sensor.
As the further improvement of above-mentioned technology, described reaction tube rear portion has opening.
As the further improvement of above-mentioned technology, described reaction tube is by opening connecting sensor.
Compared with prior art, the beneficial effects of the utility model are: the chlorine dioxide residual effectively can removing ClO 2 bleaching workshop section, and realize throwing in and detect integrated full-automatic process, operating efficiency is high, use cost is low, efficiently solves chlorine dioxide residual in pulp production to the etching problem of subsequent processing equipment under the prerequisite ensureing paper quality.

Fig. 1 is structural representation of the present utility model.
In figure: 1, reservoir; 2, precision metering pump; 3, control instrument; 4, oxidation-reduction potential sensor; 5, blender; 6, reaction tube.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
The wash mill of residual chlorine dioxide in a kind of pulp production, comprise reservoir 1, precision metering pump 2, control instrument 3, blender 5, reaction tube 6 and oxidation-reduction potential sensor 4, in reservoir 1, sodium thiosulfate is housed, reservoir 1 connects precision metering pump 2 input port, precision metering pump 2 pairs of medicines accurately add, and be provided with external control data wire, external control data wire is connected with control instrument 3, control instrument 3 detects data according to set parameter and oxidation-reduction potential sensor 4, control precision metering pump 2 and drop into sodium thiosulfate amount, precision metering pump 3 delivery outlet is connected to blender 5, the pulp solution of blender 5 input port input containing chlorine dioxide residue, blender 5 delivery outlet coupled reaction pipe 6 input port, reaction tube 6 delivery outlet connects wash engine, reaction tube 6 makes sodium thiosulfate and chlorine dioxide carry out abundant hybrid reaction, reaction tube 6 rear portion is provided with opening, reaction tube 6 connects oxidation-reduction potential sensor 4 by opening, oxidation-reduction potential sensor 4 connection control instrument 3, oxidation-reduction potential sensor 4 can use in paper pulp papermaking environment, measure oxidation-reduction potential in raffinate, and data are transferred to control instrument 3, control instrument 3 is again according to the injected volume of Data Control precision metering pump 2.
During utility model works, sodium thiosulfate is accurately rendered in blender by precision metering pump 2, what sodium thiosulfate and bleaching tower flowed out contains chlorine dioxide pulp solution, mix in a mixer, flow in the reaction tube 6 of blender 5 rear end again, make sodium thiosulfate and the abundant hybrid reaction of chlorine dioxide, sodium thiosulfate and chlorine dioxide reaction equation are 5Na2S2O3+8CLO2+9H2O=10NaHSO4+8HCL, the method generating sulfate and hydrochloric acid with sodium thiosulfate and chlorine dioxide reaction removes chlorine dioxide, reaction tube 6 rear end is by the oxidation-reduction potential sensor 4 put, transfer data to control instrument 3, control instrument 3 is according to the parameter of setting, this parameter sets according to former Water oxidize reduction potential value, commander's precision metering pump 2 drops into the amount of sodium thiosulfate, remove the sodium thiosulfate throwing amount of residual chlorine dioxide according to reaction equation 5Na2S2O3+8CLO2+9H2O=10NaHSO4+8HCL, can obtain sodium thiosulfate throwing amount is 1.6 times of chlorine dioxide residual amounts, thus reach the Automatic Control of dispensing detection, after general chlorine dioxide drift, remnants should control at below 0.01g/L, be 10% as pulp is dense, the residual water that then absolute dried paper pulp per ton produces is about 9000L, namely containing chlorine dioxide is 0.01 × 9000=90 gram, sodium thiosulfate throwing amount is 1.6 × 90 grams=144 grams, the technical grade sodium thiosulfate price at factory is 1200 yuan/T, to process needed for absolute dried paper pulp theory per ton 0.144 × 1.2 yuan=0.1728 yuan, visible hypo-elimination chlorine dioxide has stronger economy, and prove through experiment, use hypo-elimination chlorine dioxide, pulp quality is had no effect, and the chlorine dioxide residual efficiently solved in pulp production is to the etching problem of subsequent processing equipment.
The foregoing is only the utility model preferred embodiment; not thereby embodiment of the present utility model and protection domain is limited; to those skilled in the art; the equivalent replacement that all utilization the utility model descriptions and diagramatic content are made and the scheme that apparent change obtains should be recognized, all should be included in protection domain of the present utility model.
