Above-mentioned Chinese patent, the content that it has described dioxide peroxide in a kind of gas of producing pure chlorine dioxide producer, production can reach 95%, its purity reaches chlorine and dioxide peroxide mixed gas reoxidation by oxygenant at pure gas chamber, and the reaction of Potcrate and hydrochloric acid is also not thorough, also insufficient, also not rapid in its secondary reactor; After explosion-proof equipment used, the mixed gas of dioxide peroxide and chlorine directly entered atmosphere, can produce ill effect even cause serious personal injury accident environment, operator, and simultaneously, rupture disk can't use repeatedly, essential replacing in time.

Technology contents:

Technical barrier to be solved in the utility model is: make the reaction of hydrochloric acid and Potcrate more thorough, more abundant, rapider, and the explosion-proof equipment of this device can use no chlorine discharging, safety and environmental protection repeatedly.

Technical solution of the present utility model is achieved in that

Explosion-proof environment-friendly type chlorine dioxide generator, comprise: head tank, throttling valve, A reactor, second reactor, the A reactor well heater, water sprayer, inlet pipe, the reactor connecting pipe, water shoot, water inlet pipe, escape pipe, pipe connecting, and: head tank passes through pipe connecting, throttling valve and A reactor on the pipe connecting communicate, A reactor links to each other with second reactor by the reactor connecting pipe, inlet pipe respectively with A reactor, second reactor links to each other, and the bottom of close respectively A reactor in the air outlet of inlet pipe and second reactor, outside A reactor, also be socketed with an A reactor well heater, A reactor has escape pipe to link to each other with two water sprayers respectively with the second reactor internal upper part, be provided with water inlet pipe on A reactor heating container top, water shoot is arranged at the bottom, simultaneously, second reactor also is socketed with a second reactor well heater outward, second reactor well heater top is provided with water inlet pipe, water shoot is arranged at the bottom, at A reactor, second reactor top has pipe connecting and explosion-proof check valve to communicate respectively, and explosion-proof check valve links to each other with absorption unit by pipe connecting.

In the above-mentioned explosion-proof check valve dividing plate is arranged, and central authorities are porose, and a mass is arranged on the dividing plate, the external diameter of this mass is less than the internal diameter of explosion-proof check valve.

Sulfothiorine is housed in the absorption unit.

In technical solution of the present utility model, outside second reactor, be socketed with a second reactor well heater, second reactor is heated, the temperature of heating is 80 ℃, the Heating temperature that is higher than A reactor, make hydrochloric acid and Potcrate reaction in the second reactor more thorough, more abundant, rapider, the weight of the mass in the explosion-proof check valve is according to one, the safe pressure that second reactor and all pipelines can bear sets, and the weight of mass is less than one far away, the safe pressure value that second reactor and pipeline bore, when one, pressure in the second reactor is during greater than the weight of mass, gas backs down mass, enter absorption unit, chlorine is wherein absorbed rapidly by Sulfothiorine, and the eliminating of safety, and environmental-protecting performance is high, one, reactant in the second reactor is through thorough, fully, the eliminating of reaction rapidly and energy safety has no adverse effects to environment.
