Intermittent reaction constant dosing chlorine dioxide preparation device and method

Abstract

The invention discloses an intermittent reaction constant dosing chlorine dioxide preparation device which comprises a shell and a controller, wherein the shell is internally provided with a hydrochloric acid tank, a sodium chlorite tank, a raw material feeding measuring pump, a disinfectant measuring pump and a reactor; the hydrochloric acid tank and the sodium chlorite tank are respectively connected with the raw material feeding measuring pump; the reactor is respectively connected with the raw material feeding measuring pump and the disinfectant measuring pump; a hydrochloric acid low liquid level switch is arranged at the bottom of the hydrochloric acid tank; a sodium chlorite low liquid level switch is arranged at the bottom of the sodium chlorite tank; a travel switch is arranged on the reactor; and the hydrochloric acid low liquid level switch, the sodium chlorite low liquid level switch, the travel switch, the raw material feeding measuring pump and the disinfectant liquid measuring pump are connected with the controller. The intermittent reaction continuous feeding chlorine dioxide preparation device can realize constant operation, and is simple in process and convenient in installation operation; by utilizing a micro positive pressure full liquid phase flexible soft reactor, the method and the device for producing the chlorine dioxide disinfectant in an intermittent reaction constant dosing mode can realize dosing point high positive pressure dosing.

Description

technical field [0001] The invention relates to the technical field of chlorine dioxide preparation, in particular to a chlorine dioxide preparation device and method for continuous dosing in intermittent reaction. Add to realize the high positive pressure dosing of chlorine dioxide disinfectant at the dosing point. Background technique [0002] At present, the internal space of the chlorine dioxide equipment reactor is fixed, and there is a certain gas phase space in the equipment. The equipment operates under negative pressure, and the generated chlorine dioxide is mixed with the power water through the water ejector and transported to the dosing point. Due to the characteristics of the water ejector itself The pressure at the dosing point is generally less than 0.1Mpa, and the equipment is large and each system is scattered. It is mainly used in large water plants or sites with low pressure at the dosing point. The disadvantage of this method is: 1. The concentration of ...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: 1. The concentration of disinfectant is low and the flow rate is large

2. For positive pressure dosing, a separate corrosion-resistant power pump, corresponding intermediate tank, gas-liquid separator and linkage control are required. 3. The scattered installation of equipment is complicated

It is especially suitable for disinfection of water supply and pressurized places in small towns and rural areas. It solves the problem that the reaction of chlorine dioxide in the current market is not easy to control, and the use of water injectors can not be used for high-pressure dosing points, and the dosage is difficult to control.
