Description
Technical field
The utility model relates to a kind of feeding device, particularly a kind of feeder of using in the dioxide peroxide preparation process.
Background technology
In the last thirty years, dioxide peroxide has obtained widespread use as a kind of novel sterilization oxygenant in developed country, is a kind of good sterilization oxygenant that replaces liquid chlorine.In the water of chlorine dioxide treatment, can not produce the common carcinogens haloform that forms during with disinfection by chlorine, its security is classified as the AI level by the WHO of the World Health Organization, have wide spectrum, quick-acting, nontoxic, consumption is few, drug effect is long, sterilization effect is not subjected to plurality of advantages such as pH value restriction, can reach 100% to the killing rate of part bacterium; Use some reducing metal ion such as Fe in all right oxidizing water of disinfection by chlorine dioxide
2+, Mn
2+Deng, can remove iron, manganese element in the water.
Present stage, a lot of water factories of China also bring into use dioxide peroxide to replace liquid chlorine to the tap water disinfection.When adopting the R11 legal system to be equipped with dioxide peroxide, its reaction equation is seen Chemical formula 1:
2NaClO
3+H
2O
2+2H
2SO
4＝2ClO
2+O
2+2NaHSO
4+2H
2O 1
In actual applications, the various chlorine dioxide generators of existing employing R11 method all are with the Venturi meter feeder liquid sodium chlorate, liquid sulfuric acid, three kinds of liquid starting materials of liquid hydroperoxide and warm air at first to be carried out gas-liquid mixed, begin chemical reaction this moment and generate chlorine dioxide; Then gas-liquid mixture is sent into gas-liquid separator and carried out gas-liquid separation, the chlorine dioxide of generation is derived through pipeline, and isolated liquid imports reactor further reaction and the more chlorine dioxide of lasting generation through pipeline.Blast easily because of chlorine dioxide gas concentration surpasses at 10% o'clock, this process must be carried out under negative pressure usually, so that in time derive chlorine dioxide by pipeline.
In above process, gas-liquid mixed and gas-liquid separating step all require the efficient that reaches higher, improving the reaction efficiency and the dioxide peroxide transformation efficiency of total system, and guarantee reaction safety.The major defect of this mode is: first, the two itself is the step of mutual contradictory for gas-liquid mixed and gas-liquid separation, constitute from entire system, the efficient of Venturi meter and gas-liquid separator is high more, it is just high more to be used to the merit of cancelling each other in the total system, even use the lower deflector type gas-liquid separator of separation efficiency, also still have the merit loss of considerable part formerly to carry out gas-liquid mixed and carry out again among this process of gas-liquid separation for the consideration of cost and antiseptic property; Second, generally, system's negative pressure is to be provided by the water sprayer that dioxide peroxide is added to the water body place, drive raw material and enter the malleation that various feedstock pump/valve provided of Venturi meter not only not contribution of system pressure, also need water sprayer to provide extra negative pressure to be offseted, system's negative pressure is remained within the nominal scope, increased the demand of total system virtually for energy; The 3rd, on system architecture, this serial system of commissioning pipe/pump → Venturi meter gas liquid mixer → gas-liquid separator → reactor constitutes comparatively complicated, and the working efficiency of each subsystem all can not reach or near separately the best, and can only get the compromise under the entire system balance.

The feeder of using in the dioxide peroxide preparation process of the present utility model is installed on the top of reactor, and connects as one structure with reactor; Comprise the Y type mixing filling tube that is positioned at described feeder, two arms of Y type mixing filling tube one side are communicated with the two-way carrier pipe respectively, opposite side is communicated with reactor, is used to mix the two-way liquid starting material and carries out initial action and mixed liquid starting material is added in the reactor.
Preferably, feeder also comprises the warm air input tube, and the warm air input tube is positioned at the corresponding position of Y type mixing filling tube, is used to keep the initial action desired reaction temperature and derives the chlorine dioxide that initial action forms.
Preferably, Y type mixing filling tube comprises expansion section, contraction section and synthesis stage; At expansion section and contraction section place, liquid starting material atomizes under pressure and forms the gas-liquid mixed state; Two arms combine the formation synthesis stage in contraction section bottom separately, and the liquid starting material after the atomizing is in the synthesis stage mixing and carry out initial action.
Preferably, offer a plurality of breather holes on the tube wall of synthesis stage, breather hole communicates with gas output tube, is used to derive the chlorine dioxide that initial action forms.
Preferably, synthesis stage is the flaring shape along the mixed solution flow direction.
Preferably, feeder is communicated with gas output tube by pressure transmitter and safety valve, is used to control the pressure and the concentration of the chlorine dioxide of generation.
Compared with prior art, the utlity model has following beneficial effect:
1, feeder carries out batch mixing by Y type mixing filling tube, the chlorine dioxide that mixes the generation of liquid initial action is delivered directly in the gas output tube, need not to use Venturi meter of the prior art and gas-liquid separator, reactive system is simplified more, can effectively improve reaction efficiency;
2, the design of Y type mixing filling tube expansion section, contraction section, making liquid starting material atomizing rapidly under the effect of pressure becomes the gas-liquid mixed state; The liquid starting material of two kinds of atomizings mixes the synthesis stage mixing and begins to carry out initial action in the Y type, and the breather hole of offering on the tube wall of the chlorine dioxide that is produced by synthesis stage is derived rapidly, and initial action efficient is higher.
