Description

The present invention relates to a deodorizing device, and more particularly to a deodorizing device that removes malodorous substances in the air by using a humic deodorant and activated carbon.

Conventionally, combustion technology, chemical cleaning method, activated carbon adsorption method, photocatalyst method, soil deodorization method, aeration method, etc. are known as techniques for removing bad odors, but maintaining deodorization equipment with high deodorization effect and low cost A targeted improvement is desired.

As a typical odor removing technology, there is an activated carbon adsorption method. Activated carbon is used in many deodorization facilities because it can adsorb various substances depending on the material and manufacturing method.

In addition, a humic deodorant containing humic substances (humic acid, fulvic acid, humin, etc.), which are organic substances in soil, as a main component has also been developed. The deodorizing effect of this humic substance deodorant is that the functional groups such as carboxyl group and phenol group of the humic substance serve as a ligand to form a chelate compound, and the humic substance causes soil microorganisms to propagate. Due to the combined function of biological deodorization and some physical deodorization performed, long-term use is possible.

For example, in Patent Document 1, a packing layer of humic deodorant is installed in a plurality of stages, and a malodorous gas is sent in series to these packing layers to deodorize, and when the deodorizing efficiency is lowered, the packing layer of the first stage is renewed. There is disclosed a method of deodorizing a malodorous gas in series from the second packed layer with the updated packed layer as the final stage. By this deodorizing method, the deodorizing ability of the deodorant can be maintained for a long period of time.

The humic deodorant used in the deodorizing device described in Patent Document 1 has an excellent removing ability in removing hydrogen sulfide, which is the main cause of malodor, but the removal performance of hydrogen sulfide and the like deteriorates with use ( The deodorant breaks through), and eventually the deodorant performance is lost and it becomes necessary to replace it.

In order to maintain a continuous effective deodorizing effect in the dry deodorizing device, the deodorizing agent should be filled in an amount sufficient for the amount of malodorous substances generated and replaced before the deodorizing agent filled breaks through. There is a need.

Further, it is desirable that the deodorant is replaced by making full use of the remaining capacity of the deodorant and not putting an environmental load on the surrounding environment due to poor deodorization. In order to replace the deodorant at an appropriate time, the remaining capacity of the deodorant is measured.

However, it is difficult to measure the deodorizing performance remaining in the deodorant during use in a deodorizing device that has started to be used once. Therefore, it is usually estimated by sampling the odor at the outlet of the deodorizing device and measuring the malodorous substance. In the case of this method, replacement of the deodorant will be considered and implemented after the treated substance is detected by the deodorizer, and the malodorous substance may leak to the surroundings, which may impose an environmental burden.

A method of providing a processing gas sampling port in the middle portion of the deodorizing device and collecting the processing gas in the middle portion is also effective as a method for estimating the time to replace the deodorant. However, this method can also be implemented only with a device that has a structure that can collect gas in the middle part, and the operation status of the deodorizing device at the time of collection (type and content of malodorous substances in raw gas, raw gas There is also a problem that it is not always sufficient as an index of the replacement time of the deodorant in the deodorizing device, because it is easily affected by the flow velocity and humidity).

As a method of measuring the residual performance of the deodorant itself, it is also experimentally conducted to take out the deodorant from the deodorizer in use, test the deodorant performance of the collected deodorant in a laboratory, etc., and compare it with a new deodorant. ing.

As a simple method of estimating the residual deodorizing performance of a deodorant, Non-Patent Document 1 discloses that the activated carbon in use is taken out from the deodorizing device and its residual performance is estimated by measuring its pH and the like. ing.

The method of Non-Patent Document 1 is an effective method for measuring the residual performance of the deodorant, but it is necessary to stop the deodorizing device in operation once in order to collect the deodorant. In addition, it is necessary to open the lid of the deodorizing facility that has been stopped and collect the deodorizing agent from a cartridge or the like filled with the deodorizing agent.

When collecting from a cartridge, etc., power such as a chain block and heavy machinery are required to move the heavy cartridge, and the capacity of the cartridge is large, so the deodorant can be stabilized from an appropriate part. Is difficult to collect.

It is a figure explaining the appearance of the collection mouth used for the deodorizing device of the present invention. It is a figure showing an example of an instrument used for taking out a deodorant.

An embodiment of the deodorizing device according to the present invention will be described below with reference to FIGS. 1 and 2.
The present invention provides a packing layer (2, 3) filled with a deodorant, and the air passes through the inside of the packing layer, thereby forming the packing layer in a deodorizing device 1 for removing a malodorous substance in the air. It is characterized in that a collection port (22, 23) that can be opened and closed is provided on the wall surface 20 of the housing to collect the deodorant disposed in the housing.

As the deodorizing agent used in the deodorizing device of the present invention, it is possible to use an existing deodorizing agent such as a humus deodorizing agent or activated carbon. Further, the filling layer (cartridge) for filling the deodorant is not limited to a single cartridge, and a plurality of cartridges can be stacked and used as shown by reference numerals 2 and 3 in FIG.

In FIG. 1, air is introduced (Gin) from the lower side surface of the deodorizing device 1 and discharged (Gout) from the upper side surface. Then, a plurality of stages (two stages in FIG. 1) of cartridges, which are deodorant-filled layers, are arranged in the deodorizing device 1, and the processing air is configured to pass through the cartridges. The arrangement of the cartridge and the position at which the air is introduced into or discharged from the deodorizing device are not particularly limited to those shown in FIG. 1, and various modifications can be made depending on the nature and situation of the air.

A deodorant in the form of pellets, which is solidified to a predetermined size, is arranged in the casing of the filling layer that constitutes the cartridge. An opening that allows air to flow is formed on the bottom surface side of the filling layer, and a support structure that allows the deodorant to be placed in the cartridge is provided. Specifically, the bottom surface of the filling layer is formed by honeycomb-shaped grating, and the mesh sheet is arranged on the bottom surface of the filling layer to mount the deodorant.

As shown in FIG. 1, the deodorizing device 1 has a cartridge (2, 3) serving as a filling layer arranged inside the outer container. FIG. 2 shows a state of the sampling port, in which a cylindrical sampling tube 22 is arranged on the wall surface 20 of the casing of the filling layer (cartridge), and further, an inner cap for closing the outlet of the sampling tube 22. 23.

The sampling pipe 22 is installed at an intermediate portion in the height direction or the width direction of the filling layer in order to collect the deodorizing agent in the intermediate portion of the deodorizing agent in the filling layer (cartridge). The sampling tube 22 extends from the wall surface 20 toward the inside by about 100 mm. As a result, the deodorant in the portion near the center of the cartridge can be collected. The sampling tube 22 is preferably made of a metal such as SUS that is resistant to corrosion. Further, in order to prevent the deodorant from flowing out more than necessary during the deodorant collection operation, it is desirable to have a structure in which the vicinity of the inner tip of the collection tube 22 is opened downward and is obliquely cut.
