Description

[Detailed description of the invention] The present invention relates to improvements in deodorizing devices.

Conventionally, this type of deodorizing device has various structures,
For example, a rotary shaft equipped with brushes is installed in a cylindrical deodorizing chamber with an inlet tube for malodorous gas at one end and an outlet tube at the other end, and a chemical solution injection tube is installed in parallel in the deodorizing chamber to spray the chemical solution onto the top of the brush. This structure deodorizes the foul-smelling gas introduced into the deodorizing chamber by spraying the attached chemical liquid into a mist by the rotational force of the brush (Japanese Patent Laid-Open No. 1983-1999).
34179).

However, in the case of the above structure, since the chemical liquid poured from the top of the brush is scattered by the brush rotating at high speed, the chemical liquid is mainly scattered in the direction of rotation of the brush, and the concentration of the atomized chemical liquid between the upper and lower parts of the deodorizing chamber is significant. This has the disadvantage of causing changes and reducing deodorizing efficiency.
On the other hand, there are disadvantages and inconveniences, such as the need to inject a large amount of a chemical solution in order to maintain a constant concentration of the atomized chemical solution indoors.

For this reason, there has been a long-standing desire in the industry for a deodorizing device that uses less chemical solution and can fill the entire room with a mist of chemical solution without any concentration difference, but such a device does not currently exist. do not.

The present invention is a novel deodorizing method that satisfies the above requirements by injecting a chemical solution from the injection hole of a hollow rotating shaft equipped with a stirring brush, and aims to downsize the deodorizing chamber, improve deodorizing efficiency, and reduce the amount of chemical solution used. It provides equipment.

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

The deodorizing device according to the present invention includes a deodorizing chamber main body 1, a motor storage chamber 3 for driving a hollow rotating shaft 12 of the main body 1, and a chemical solution storage tank 2 for delivering a chemical solution to the rotating shaft 12.

The motor storage chamber 3 and the chemical storage tank 2 are partitioned and housed in the base at the bottom of the deodorizing chamber main body 1, and the motor 31 in the motor storage chamber 3 is connected to the rotating shaft 12 by a pulley 33 and a drive belt 32, and the storage tank 2 communicates with the rotating shaft 12 via a connecting pipe 21, a pump 22 is provided in the connecting pipe 21, and a circulation pipe 23 is formed between the deodorizing chamber main body 1 and the storage tank 2 to supply the chemical solution. is designed to circulate between the tank 2 and the main body 1.

The deodorizing chamber main body 1, which is a feature of the present invention, has a hollow rotating shaft 12 supported in the longitudinal direction in a cylindrical chamber body 11, and chemical injection holes 13 are bored in the rotating shaft 12 at regular intervals in the axial direction. A stirring brush 14 is provided between each injection hole 13, 13, and a multiple net 15 made of, for example, three layers of fine mesh made of stainless steel or other material is provided around the inner wall of the chamber body 11. 1 An intake pipe 16 for introducing malodorous gas 4 is formed at one end of the outer periphery, and an exhaust pipe 17 is formed at the other end, and the intake pipe 16 is offset toward the front side in the rotational direction of the hollow rotating shaft 12 with respect to the chamber body 11. A secondary deodorizing chamber 18 is provided in the exhaust path of the exhaust pipe 17 so that the introduced malodorous gas 4 is attracted to the rotating airflow caused by stirring by the brush 14.

In addition, in the embodiment, a deodorizing device having one deodorizing chamber main body 1 was shown, but in implementation, a plurality of deodorizing chamber main bodies 1 may be arranged in parallel or in series. In this case,
Each body is connected with a communication pipe, and the first body is connected to the malodorous gas 4.
By forming the intake pipe 16 and the exhaust pipe 17 in the final body, the deodorizing effect becomes even higher.

Therefore, the malodorous gas 4 is transferred from the intake pipe 16 to the chamber body 1.
1. At this time, a rotating airflow is generated within the chamber body 11 due to the rotation of the stirring brush 14.
On the other hand, the rotating shaft 12 injects the chemical liquid sent from the tank 2 from the injection hole 13 toward the entire circumference inside the chamber body 11, and at the same time, the stirring brush 14 diffuses the injected chemical liquid to form a mist, and spreads the injected chemical liquid all over the inside of the chamber body 11. Fill it with no difference in concentration. In this state, the malodorous gas 4 drawn by the rotating airflow and flowing through the chamber body 11 mixes with the mist-formed chemical solution and is deodorized. Furthermore, since the chemical liquid forms a thin film between the fine meshes of the multiple net 15, the malodorous gas 4 also comes into contact with this film and is deodorized. The deodorized gas is then sent to the exhaust pipe 1.
7 and passes through the exhaust pipe 17, it is secondarily deodorized by the secondary deodorizing chamber 18 and can be discharged outside the deodorizing chamber main body 1 as an odorless gas.

As described above, the present invention provides an injection hole 13 in a cylindrical chamber body 11 having an intake pipe 16 at one end and an exhaust pipe 17 at the other end.
A hollow rotating shaft 12 equipped with a stirrer brush 14 and a stirring brush 14 is provided, and the rotating shaft 12 and the chemical storage tank 2 are communicated through a connecting pipe 21, and a net 15 is installed on the inner wall of the cylindrical chamber body 11. Because it is placed around the chamber, the foul-smelling gas that has flowed into the chamber mixes with the atomized chemical solution and is deodorized. Moreover, since the chemical liquid is injected from a hollow rotating shaft, there is no need for a chemical injection pipe as in the past, and a small amount of chemical liquid effectively turns into a mist, filling the entire room with no concentration difference and causing a foul-smelling gas. can achieve efficient deodorization. In addition, the net provided around the inner wall of the chamber can supplement the deodorization of malodorous gases, achieving the remarkable effects of achieving the object of the invention.
