Description

[Detailed explanation of the idea]

[Industrial Application Field] The present invention relates to a deodorizing device, and particularly to a deodorizing device for deodorizing odorous gas such as ammonia-containing gas. [Prior Art] Some conventional deodorizing machines use a base or liquid deodorizing agent or a deodorizing agent to deodorize or eliminate odors. For example, in some devices that use solid activated carbon, the activated carbon is placed in a cartridge, and odor gas is passed through the cartridge to deodorize by adsorption. In addition, in some cases, a liquid is used, in which a deodorizing agent or an aqueous solution containing a deodorizing agent is brought into contact with a odorous gas, and deodorization is carried out by adsorption or reaction. [Problems to be solved by the invention] Among the conventional deodorizing machines mentioned above, when activated carbon is used, the deodorizing ability depends on the particle size (or surface area) of the activated carbon and the amount used (the shape of the cartridge, i.e., the odor gas residence time). However, if the particle size is too small, 1mm
If the particle size is smaller than that, the expected flow will be poor, and the duration of adsorption capacity will be shortened if the particle size is small. There is. Furthermore, due to the physical strength of activated carbon, if it is packed too tightly, the particles may be destroyed. In the case of activated carbon, the adsorption mechanism is essentially the activated carbon surface, but in reality the cartridge must be replaced before the adsorption capacity of the surface reaches saturation.
In addition, when containing low molecular weight polar substances such as ammonia-containing gas, the adsorption power is weak, and although it is common to impregnate reactive components into the pore spaces of activated carbon, it has disadvantages such as not being immediately effective. It is something. On the other hand, when deodorizing and deodorizing using liquid,
There is an explosion method that simply passes odor gas into the liquid, but this method sprays a liquid such as deodorant into a partitioned room from a shower or spray nozzle. Odor gas is introduced and brought into contact, and deodorization occurs through adsorption or reaction.
In this case, in order to increase the throughput, the basic method is to reduce the spray particle diameter and increase the spray amount. However, if this condition is to be met, for example in the case of a spray nozzle, it can be solved by reducing the diameter of the nozzle, but as the diameter is reduced, the pump used must have a higher output. As the device itself has become larger, the amount of deodorant used has also increased, and it has been a hassle to replace the deodorant. Therefore, the above-mentioned method not only has a high running cost, but also has to deal with accompanying disturbances such as noise, and has the disadvantage that the apparatus becomes larger and the cost increases further. [Means for Solving the Problems] The present invention was devised to solve the above-mentioned problems with the conventional technology. The odorless gas is sprayed indoors, and the odorless gas is brought into contact with the deodorizing spray particles while passing through the deodorization chamber, and then the odorless gas is exhausted from the exhaust port of the blower via a filter and a gas exhaust pipe. In order to adjust the number of deodorizer or deodorant spray particles per unit volume according to the concentration of odor components of odorous gas, the number of generated deodorant or deodorant spray particles can be adjusted. It is characterized by being configured so that it can be adjusted using an ultrasonic generator. [Example] Hereinafter, the configuration of the present invention will be explained based on the drawings.
In the drawings, FIG. 1 is a partially cutaway side view of the deodorizing device of the present invention, FIG. 2 is a partially cutaway rear view, and FIG. 3 is a front view. A blower 12 is disposed on the base 1, and a particle generation chamber 16 and a deodorizing chamber 3 are disposed above the blower 12. In the particle generation chamber 16, the deodorant or deodorizer is turned into particles by the ultrasonic generator 5, and the particle delivery pipe 1
4 and is sprayed into the deodorizing chamber 3. A odorous gas such as ammonia-containing gas is sucked into the deodorizing chamber 3 through the gas inlet 2, is deodorized by contacting with the deodorizer or the spray particles 6 of the deodorizer, and is passed through the filter 7 to the outside of the spray particles 6. The odorless gas is discharged from the exhaust port 10 of the blower 12 via the gas discharge pipe 9. In the figure, 8 is a damper for adjusting the flow rate, and the damper 8 is used as a motor drive to control the control panel 14.
It is also possible to configure a control circuit (not shown) that automatically adjusts the flow rate by the operation of . Further, the heater 13 is for dehumidification,
It can be used depending on the indoor situation where odorless gas is to be discharged, and this is also done by operating the control panel 15. In the figure, reference numeral 11 is a drain for removing the used deodorizing liquid in which the spray particles 6 have been stopped by the filter 7. A control circuit that adjusts the number of deodorizer or deodorizer spray particles per unit volume according to the odor component concentration of the odorous gas using the ultrasonic generator 5, and controls the flow rate adjustment in conjunction with the damper 8 ( (not shown), and the used deodorizing liquid is discharged from the drain 11 just before saturation. By the way, if the service tank 19 is used as shown in Fig. 3, the amount of deodorizing agent or deodorizing agent consumed can be replenished by adjusting the valve 20 via the pipe 19, and by keeping the liquid level constant, ultrasonic waves can be applied. This makes it possible to stabilize the particle size and amount of particles generated. The following are specific examples. A deodorization test was carried out on the ammonia-containing gas discharged from the ammonia developing machine for diazo photosensitive paper using the above-mentioned apparatus, and the results are as follows. Ammonia developing machine: Ammonia-containing gas discharged from an ammonia dry developer model KD1000 manufactured by Seiwa Sakaguchi Co., Ltd. was introduced into the gas inlet 2 using a duct at a flow rate of 3.2 m ³ /min. At this time, the concentration at the gas inlet and the concentration at the exhaust port 10 are
The results of measurement according to JIS-K-0099 (indophenol method) were as shown in the table below.

[Action and effect]

Since the deodorizing device of the present invention has the configuration described above, it has many advantages such as better deodorizing efficiency than conventional devices, the device can be configured more compactly, and running costs can be lowered, so it has practical value. This is a very clever idea.
