Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a deodorizing and purifying liquid which dissolves, adsorbs, or decomposes odorous substances, air pollutants, and suspended particulates in a gas, and a method for using the same.

[0002]

2. Description of the Related Art In the conventional deodorizing and purifying treatment, a gas to be treated is basically brought into contact with a predetermined deodorizing and purifying agent to remove odorous substances, air pollutants and suspended particulates in the gas. It is dissolved, adsorbed, or decomposed. At this time, a deodorant purifying agent is generally set according to the type and properties of the odorous substances, air pollutants, suspended particulates and the like in the gas.

[0003]

However, the conventional system has the following problems. The odorous substances, air pollutants and suspended particulates in the gas to be treated are often composed or mixed of various substances, and it is not possible to cover all with a single deodorant and purification agent. In addition, the properties of the substance to be removed can be roughly classified into hydrophilic and hydrophobic properties. However, deodorant purifying agents effective for removing a hydrophilic substance have a small effect on a hydrophobic substance, and conversely. In most cases, the deodorizing and purifying agent effective for removing a hydrophobic substance has little effect on a hydrophilic substance. With the removal treatment, substances dissolved or adsorbed in the deodorizing and purifying agent are accumulated, particularly in the case of odorous substances, etc., when the substance concentration due to accumulation reaches a certain level or more.
Since the odor substance once dissolved or adsorbed exhibits re-evaporation, it is necessary to replace the deodorant purifying agent each time. When the removal treatment is performed by combining a plurality of types of deodorizing and purifying agents, there is a problem that droplets and vapors of each deodorizing and purifying agent move and are mixed into the next deodorizing and purifying agent, thereby greatly impairing its action. For this reason, a separate device for removing the splash and vapor is required, and an independent facility is often required for each deodorizing and purifying agent.

[0004] The present invention provides a deodorizing and purifying agent for effectively dissolving or adsorbing odorous substances, air pollutants and suspended particulates in a gas to be treated, and a deodorizing purifying agent for decomposing substances once dissolved or adsorbed. By devising an odor purifier and devising a method of using the deodorant purifier, the concentration of the substance once dissolved or adsorbed can be increased without impairing the ability to dissolve or adsorb or decompose the substance to be treated. In addition to suppressing the performance degradation of each deodorant purifying agent due to the movement and mixing of each deodorant purifier, the frequency of replacement of the deodorant purifier is reduced, and installation of a device for removing droplets and vapors is also required. Its purpose is to omit it.

[0005]

In order to achieve the above object, first, the following three types of deodorizing and purifying agents have been devised. A liquid preparation in which several kinds of cations and a particulate material serving as a supply source of the ions are dissolved and dispersed in water, mainly for the purpose of dissolving or adsorbing a hydrophilic substance. A liquid preparation in which a particulate material serving as a supply source of several kinds of cations, mainly for dissolving or adsorbing a hydrophobic substance, is dispersed in a vegetable oil, a mineral oil, or a mixed oil of both. A liquid preparation in which a microorganism and several kinds of cations and a particulate material serving as a supply source of the ions are dissolved and dispersed in water, mainly for the purpose of decomposing a substance once dissolved or adsorbed.

Next, a method of using the above deodorizing and purifying agent was devised as follows. A) When the substance in the gas to be removed is both hydrophilic and hydrophobic, first, the gas is brought into contact with the above-mentioned deodorizing and purifying agent to remove mainly the hydrophobic substance in the gas. After being dissolved or adsorbed in the deodorizing / purifying agent of the present invention, secondly, it is brought into contact with the above-mentioned deodorizing / purifying agent, and thereafter, thirdly, it is brought into contact with the above-mentioned deodorizing / purifying agent, and mainly hydrophilic in the gas. Fourth, after dissolving or adsorbing the toxic substance in the deodorizing / purifying agent, fourthly, it is brought into contact with the above-mentioned deodorizing / purifying agent, and then exhausted. B) When the substance in the gas to be removed is hydrophilic, first, the gas is brought into contact with the deodorizing and purifying agent, and the substance in the gas is dissolved in the deodorizing and purifying agent. Alternatively, after being adsorbed, secondly, after being brought into contact with the above-mentioned deodorizing and purifying agent, exhaust is performed.

[0007] By the above deodorant purifying agent and its use method,
The problem of the conventional method is solved as follows.

[0008] By using a liquid agent suitable mainly for dissolving or adsorbing a hydrophilic substance and a liquid agent mainly adhering to dissolving or adsorbing a hydrophobic substance together, an odorous substance in a gas to be treated, an air pollutant, Most of the suspended particulates can be collected.

By using together a liquid agent suitable for decomposing the substance once dissolved or adsorbed, the substance trapped in the deodorizing and purifying liquid agent is continuously decomposed, thereby suppressing or reducing the concentration increase. The replacement period of the deodorizing and purifying agent is extended.

[0010] Sprays and vapors from a liquid agent suitable for dissolving or adsorbing a hydrophilic substance or a liquid agent suitable for dissolving or adsorbing a hydrophobic substance are always deodorant purifying agents having a function of decomposing the collected substances. , And is decomposed together with the collected substances, so that it is hardly impaired in its function or effect when mixed into the next deodorizing and purifying agent. Therefore, it is possible to omit the device for removing the droplets and vapor.
