The technical solution of the utility model is: a kind of ramp type chlorine dioxide reaction device, it is by housing, the opening for feed pipe, pre-mixing nozzle, gaseous phase outlet, the raffinate outlet, swash plate, circuitous runner, heating tube and aeration tube constitute, the opening for feed of Textone and hydrochloric acid is positioned on the housing upper wall, the opening for feed pipe front end of Textone and hydrochloric acid is separately installed with reverse checkvalve, end is connected with two input apertures that are positioned at the intravital pre-mixing nozzle front end of shell respectively, 5 interlaced swash plates are positioned at the housing middle part, every swash plate is fixed on the inner walls horizontal by 30 ° of oblique angles, be staggeredly equipped with overflow port and the drainage trough that is connected with overflow port in the outer of swash plate, circuitous runner is positioned at the housing bottom, interlaced by 4, uprightly, the baffle plate that is fixed on the inner walls constitutes, heating tube and aeration tube are circuitous shape and are arranged in the circuitous runner, aeration tube is positioned under the heating tube, the raffinate outlet is arranged on circuitous runner end, on the upper shell wall, water shoot passes the inner water shoot of raffinate outlet opening housing and extends the housing inner bottom part, aeration tube and heating tube below, raffinate outlet opening housing outer end is connected with the backwash inhalent siphon by T-valve, gaseous phase outlet is arranged on case top, the same temperature-sensing probe that is horizontally installed with of raffinate outlet is provided with thermal insulation layer in the outside of housing in circuitous runner.
During operation, by Electromagnetic diaphragm metering pump saturated sodium chlorite solution and 31% concentrated hydrochloric acid are sent into reactor shell according to 1: 1.3 ratio, carry out penetrating after impact is mixed through pre-mixing nozzle, overflow and fully reaction step by step on every swash plate, enter at last in the circuitous runner, through 40 ℃ of heat treated, and an amount of and uniform aeration agitation, end reaction is complete, the salts solution that is generated is from flowing into the raffinate outlet, enter the blow-off line that is positioned at the reactor below, chlorine dioxide enters the dosing pipeline by the upper gaseous phase outlet under air thrust.The liquid level pressure that produces during full of liquid in circuitous runner should be less than the blast vapour pressure of chlorine dioxide.
The advantage applies that ramp type chlorine dioxide reaction device of the present utility model is compared with prior art had exists:
1, raw material availability height does not produce acid waste water.Reaction mass heats up and aeration agitation in the circuitous runner below entering again by after being detained reaction on every grade of swash plate, and all materials are fully reacted, and finally only remaining sodium chloride aqueous solution is discharged from water shoot.
2, output height.The swash plate and the circuitous flow passage structure of ramp type chlorine dioxide reaction device inside, sufficiently and reasonably utilized the institute of inside reactor to have living space, competent reaction times and smooth gas dissipation passage are provided, even under the bigger situation of reaction mass input, by an amount of elevated temperature and increase aeration rate, reaction mass is reacted completely, guaranteed the dioxide peroxide generating capacity can be between 300～9000g/h regulated at will.
3, do not produce harmful side products such as chlorine, gas purity height.Because adopting Textone and hydrochloric acid is raw material, does not have chlorine in the resultant, and because Heating temperature is lower, the concentration of hydrochloric acid that raw material uses is lower, can not cause hydrochloric acid to volatilize in a large number, has guaranteed that the purity of available gas is higher.
4, drug feeding pipeline is difficult for stopping up.Waste liquid is directly discharged through water port, does not enter drug feeding pipeline, does not exist because of the dosing pipeline is long, temperature reduces, and the sodium-chlor crystallization is constantly separated out and stops up the phenomenon of drug feeding pipeline.
5, can automatic backwash.The T-valve that is provided with in the raffinate outlet connects the backwash water inlet, when inside reactor needs backwash, can be under the prerequisite of stopped reaction, by the control T-valve, make backwash water enter inside reactor, utilize heating tube to make water temperature rise to 70 degree, cooperate violent aeration agitation simultaneously, can realize automatic backwash.
6, safe and reliable.By bubbling air, can play diluting effect to chlorine dioxide; If situations such as unexpected obstruction appear in the dosing pipeline, gaseous tension raises in the reactor, during greater than the liquid level pressure that produces during full of liquid in the circuitous runner, the liquid in the circuitous runner is forced out water shoot, and the gas in the reactor can be expelled to safe place from water shoot; Can multiple functions such as lacking material warning shutdown, chlorine dioxide concentration on-line monitoring be set in Controlling System simultaneously, guarantee security of system in all directions.
