Embodiment 1

[0022] Such as figure 1 As shown, a chlorine dioxide reaction device includes two main reactors 1 and a secondary reactor 2, and is characterized in that: two primary reactors 1 are connected in parallel to form a first-stage reaction, and the secondary reactor 2 is connected in parallel with two The main reactor 1 is connected in series to form the second-stage reaction, and the secondary reactor 2 and the gas-liquid blower 3 are connected in series to form the third-stage reaction; after the outlet pipe 21 of the secondary reactor 2 and the outlet pipe 32 of the gas-liquid blower 3 are connected It is connected to one of the main reactors 1, and the parallel outlet pipes of the two main reactors 1 are connected to the collection tank. The inlet pipes 11 of the two main reactors 1 are connected to each other and then connected to the raw material tank; the drain pipes 15 of the two main reactors are connected to each other and connected to the inlet pipe 21 in the secondary ...

Embodiment 2

[0025] Such as figure 2 and image 3 As shown, the specific implementation is the same as in Example 1, and the difference is that the structure of the main reactor 1 is that the side wall is provided with a liquid inlet pipe 11, and the top of the kettle is provided with an air inlet pipe 12, an air outlet pipe 13 and an explosion-proof device 14; The trachea 12 extends to the lower part of the reactor and is submerged by the solution. The bottom of the inlet pipe 12 is provided with stirring blades 4 , and each stirring blade 4 is provided with an air outlet 41 ; the bottom of the reactor is provided with a drain pipe 15 .

[0026] The raw material enters the main reactor 1 through the liquid inlet pipe 11 of the main reactor 1 for the first-stage reaction, and the two main reactors 1 are connected in parallel with each other. 13 are connected in parallel with each other, and the supply and discharge are carried out uniformly but independent of each other without affecting...

Embodiment 3

[0028] The specific embodiment is the same as Example 2, the difference is that: the inlet pipe 12 of the main reactor 1 is located in the middle of the top of the kettle; the stirring blade 4 is cylindrical, and the stirring blade 4 rotates around the inlet pipe 12; the air outlet 41 is along the evenly distributed around the circumference.

[0029] Stirring blade 4 itself also rotates, cooperates air outlet 41 to cause the double agitation solution of solution, promotes the carrying out of reaction.

Abstract

The invention relates to a chemical reaction device, in particular to a chlorine dioxide reaction device. The problems that the conversion efficiency is low and the structure is complicated at preset are solved. The chlorine dioxide reaction device comprises two primary reaction kettles (1) and a secondary reaction kettle (2) and is characterized in that the two primary reaction kettles (1) are connected in parallel to form first-stage reaction; the secondary reaction kettle (2) and the two primary reaction kettles (1) connected in parallel are connected in series to form second-stage reaction; the secondary reaction kettle (2) and a gas-liquid blower (3) are connected in series to form third-stage reaction; an escape pipe (21) of the secondary reaction kettle (2) and an escape pipe (32) of the gas-liquid blower (3) are connected into one of the two primary reaction kettles (1) after being communicated each other; and the escape pipes connected in parallel of the two primary reaction kettles (1) are connected into a gathering tank. The chlorine dioxide reaction device has the advantages that the structure is more optimized and the chlorine dioxide conversion rate is higher.

Description

technical field [0001] The invention relates to a chemical reaction device, in particular to a chlorine dioxide reaction device. Background technique [0002] In the past thirty years, chlorine dioxide, as a new type of disinfection oxidant, has been widely used in developed countries, and it is an excellent disinfection oxidant to replace liquid chlorine. The water treated with chlorine dioxide will not produce trihalomethane, a carcinogen that is usually formed when disinfected with chlorine gas. Its safety is listed as AI level by the World Health Organization (WHO). It has many advantages, such as long-term effect, and the bactericidal effect is not limited by the pH value. The killing rate of some bacteria can reach 100%. The use of chlorine dioxide disinfection can also oxidize some reducing metal ions in the water, and can remove iron and manganese in the water. . At this stage, many water plants in my country have also begun to use chlorine dioxide instead of liqui...
