Description

Chlorine dioxide generator {APPARATUS FOR GENERATING CHLORINE DIOXIDE}

The present invention relates to a chlorine dioxide generating device, and more specifically, using a calcium hydroxychlorite with no change over time and high chlorine concentration to improve the yield and concentration, a reaction tank in which chlorine generation and chlorine dioxide generation The present invention relates to a chlorine dioxide generating device capable of controlling toxic chlorine gas by using and separating the chlorine gas and suppressing the generation of crorate as a side reaction.

In general, chlorine dioxide has a strong sterilizing power, oxidizing power, deodorizing power and is known to be about 2.5 times stronger than other chlorine disinfectants. In addition, chlorine dioxide does not react with organic compounds to produce organic halogen-based compounds such as carcinogenic trihalomethane (THMs), haloacetic acid (HAAs), and haloacetonitrile (HANs). It is widely used as a disinfectant and deodorant. It is rapidly decomposed in nature by sunlight or temperature, and is widely known as an environmentally friendly disinfectant because it has no residual.

Looking at the method for producing a conventional chlorine dioxide as follows.

Using the paper that requires large amounts of chlorine dioxide industry and the fiber industry reducing agent for chlorate (NaClO ₃₎ to produce the salt to decompose the high temperature electrical no diaphragm sulfur dioxide, hydrochloric acid, methanol, hydrogen peroxide, formaldehyde, such as chlorine dioxide (ClO ₂₎ To manufacture.

The scheme is shown in Scheme 1 below.

[Reaction Scheme 1]

2NaClO ₃ + H ₂ O + SO ₂ → 2ClO ₂ + Na ₂ SO ₄ + H ₂ O

2NaClO ₃ + 4HCl → 2ClO ₂ + 2NaCl + Cl ₂ + 2H ₂ O

The above-mentioned method is actually a device industrial manufacturing method that requires a large investment and large facilities such as a salt refining facility, a salt electrolysis facility, and a sulfurous acid gas generating facility.

Therefore, when dozens of kilograms of chlorine dioxide is required per day, chlorine dioxide is prepared using a relatively low cost and simple chlorite as a starting compound.

At this time, chlorine, hydrochloric acid, sodium hypochlorite is used as the oxidizing agent.

The production method of such chlorine dioxide can be classified as follows.

1) Method using sodium chlorite and chlorine (Scheme 2)

[Reaction Scheme 2]

2NaClO ₂ + Cl ₂ → 2ClO ₂ + 2NaCl

2) Method using sodium chlorite, sodium hypochlorite and inorganic acid (Scheme 3)

Scheme 3

_{2NaClO 2 + NaClO + 2HCl → 2ClO} 2 + 3NaCl + H 2 O

2NaClO ₂ + NaClO + H ₂ SO ₄ → 2ClO ₂ + Na ₂ SO ₄ + NaCl + H ₂ O

3) using sodium chlorite and hydrochloric acid or sulfuric acid (Scheme 4)

[Reaction Scheme 4]

_{5NaClO 2 + 4HCl → 4ClO 2 +} 5NaCl + 2H 2 O

5NaClO ₂ + 2H ₂ SO ₄ → 4ClO ₂ + 2Na ₂ SO ₄ + NaCl + 2H ₂ O

In the application of the above three chlorine dioxide production methods on site, the first method (Scheme 2) requires careful attention and skilled knowledge in handling because chlorine, which is actually a high pressure gas, is highly toxic. It is difficult to produce low concentration and small amount of chlorine dioxide solution because safety facilities and professional handling personnel are essential.

In case of the second method (Scheme 3), sodium hypochlorite should be distributed in an aqueous solution at a concentration of 10 to 13%, and severely changed with temperature and storage conditions, and thus requires a separate refrigeration storage facility. There is this. In addition, when sodium hypochlorite is used, sodium hypochlorite enters a lot, chlorate is generated a lot, and if the hypochlorite enters less, there is a problem that less chlorine dioxide is generated.

Finally, in the third method (Scheme 4), chlorite and inorganic acid (hydrochloric acid or sulfuric acid) must be above a certain concentration so that chlorine acid disproportionately reacts to produce hypochlorite and chloric acid and generate chlorine dioxide (Scheme 5). Reference).

[Reaction Scheme 5]

2NaClO ₂ + 2HCl → 2HClO ₂ + 2NaCl

2HClO ₂ → HClO ₃ + HClO

Under these reaction conditions, which are well controlled quickly, high purity and high yield of chlorine dioxide can be obtained, but in practice, it is very difficult to satisfy the reaction conditions and the reaction is not fully progressed, resulting in high purity and high yield chlorine dioxide solution. It's hard to get.

In general, ClO ₂ ^- is that by-products such that there is effect a large impact on yield and purity, depending on how much remains in the solution out of the reaction conditions to minimize such by-product ^{_{-, ClO 3 -, Cl 2}} , ClO -, Cl Very important.

In addition, a low concentration and a small amount of chlorine dioxide, as well as a high concentration can be produced a large amount of chlorine dioxide, and also aims to be able to gasify the chlorine dioxide generated in the reaction tank to obtain pure chlorine dioxide.

In addition, by absorbing the generated chlorine dioxide gas in the zeolite or silica gel particles, it is intended to be able to transport and store in a state with little change over time in the concentration of chlorine dioxide.

In addition, it is an object to be able to precisely control the reaction amount and control the production amount by quantitatively adding the starting compounds using a solenoid valve.

It is preferred to be provided as a single Y solenoid valve. Thus, by mixing the calcium hypochlorite solution and the acid in advance before the reaction tank injection, it is possible to increase the reaction rate of the chlorine air mixed gas generation reaction in the chlorine generating reaction tank (111).

Thus, the chlorine generation reaction tank 111 is injected with a predetermined amount of calcium hypochromite solution and inorganic acid or organic acid supplied from the 1-1 storage unit 112 and 1-2 storage unit 113 through the solenoid valve 112a. Will be. At this time, the air control valve 114 is operated to inject air into the chlorine generating reactor 111.

Accordingly, in the first filter 116 provided at the end of the air inlet pipe coming into the chlorine generating reaction tank 111, fine air bubbles are generated, and the chlorine gas is generated by reacting the calcium hypochlorite solution with an acid. The chlorine gas is mixed with the fine air bubbles to rise to the top of the chlorine generating reaction tank 111.

The internal pressure of the reactor 211 can be lowered. By adjusting the pressure on the chlorine dioxide reaction tank 211, the user can control the formation of air bubbles by the filter installed in the chlorine dioxide reaction tank 211 to control the generation of chlorine dioxide in high concentration and high yield.
