Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a septic tank, an industrial waste treatment plant exhaust facility, a factory wastewater treatment facility, a kitchen detoxification facility, a sewage treatment plant, a night soil treatment plant, a garbage treatment facility, an in-vehicle dedicated duct, indoor use. The present invention relates to a portable type air purifier equipped with a forest bath breathing function and a deodorizing function which is installed and used in various equipment such as an exhaust duct.

[0002]

2. Description of the Related Art The main deodorizing method using a conventional deodorizer is an adsorption method, and especially sewage mainly containing hydrogen sulfide from various industrial waste equipment such as wastewater treatment equipment, intermediate water equipment, detoxification equipment, and septic tanks. It was the most effective method for odor.
To connect the deodorizer to the piping duct, a nozzle insertion method is used, and this is placed on the negative pressure side in front of the exhaust fan in the piping duct to improve the contact efficiency between the odorous component and the deodorizing fragrance. The distance from the exhaust port and the number of times turbulent flow is generated are taken into consideration so as to increase the number.

[0003]

However, the conventional adsorption method requires at least three layers of adsorbents such as an acidic adsorbent, an alkaline adsorbent, and a neutral adsorbent, and further, an odor component and a deodorizing aroma agent. The contact time had to be set to about 1 second or longer, and a slow ventilation speed was required. further,
It was necessary to secure a space for replacing the adsorbent. For this reason, the deodorizer itself becomes bulky, and it becomes necessary to install an extra branch duct for installing the deodorizer, which complicates the installation work on the piping duct, and also has a high capacity for exhaust. There is a problem that a fan is required and the cost is high.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a portable air purifier of high deodorizing efficiency, easy to attach to a piping duct, and energy saving and low cost type. Is.

[0005]

In order to achieve the above-mentioned object, according to the present invention, an air flow inside a housing which is a box-like air purifier having an air outlet and an air inlet. It is characterized in that a deodorizing fragrance is arranged on the route in a freely attachable and detachable manner.

Further, an electric fan for forcibly discharging the outside air sucked from the air blowing port from the air blowing port is arranged so that the storage space for the deodorizing fragrance in the housing of the air purifier is on the negative pressure side. It is characterized by

Further, the air outlet is of a pipe type nozzle type connected midway in an exhaust system passage such as a duct for piping, and the air outlet is formed by a fan-shaped partition blade rotating. A rotary slit that can freely change the opening area may be used. Alternatively, both the air outlet and the air inlet may be of a tandem type having a rotary slit that allows the opening area to be freely changed by the rotating operation of the fan-shaped partition blade.

Then, a partition wall having a plurality of openings is provided in the box-shaped air purifier housing, one chamber in the air purifier housing partitioned by the partition wall, and the partition wall. A large-diameter air-inlet pipe connected to the other compartment and a deodorant fragrance that is detachably arranged, and a large-diameter air-inlet pipe connected to the one chamber, and coaxially inserted into the air-inlet pipe. A small-diameter air outlet pipe that communicates the opening through the partition wall with the other chamber where the deodorant fragrance is placed is exposed in the exhaust system passage together, and an air volume adjusting valve is provided on the air outlet pipe side. It is characterized by having.

Further, an air blower pipe and an air blower pipe, which are joined in parallel to form a two-piece unit, are arranged in the casing of the air purifier, and an air flow control valve is provided on both pipes. It is characterized by having.

The deodorizing fragrance is composed based on a two-stage deodorizing system of membrane type or cartridge type iodine charcoal and vegetable essential oil. Further, the air outlet side corresponds to various exhaust system passages. Alternatively, a plurality of branch connectors for a duct hose that is branched into a plurality of parts may be arranged.

In the air purifier according to the present invention, an electric fan for forcibly discharging the outside air sucked from the air blowing port of the casing from the air blowing port, and detachable from the negative pressure side of the electric fan. With the deodorant fragrance placed in, the high-humidity high-concentration odor and the low-humidity low-concentration odor are exhausted to the outside together with the exhaust from the exhaust duct, which enables the function to improve the contact efficiency between the odorous component and the deodorant fragrance. . In addition, the deodorizing fragrance composed of a two-stage deodorizing method using membrane type or cartridge type iodine carbon and vegetable essential oil passes through an iodine carbon layer having an adsorption capacity three times or more that of ordinary activated carbon, and almost there. The odor component is chemically adsorbed, and a small amount of residual odor is neutralized and deodorized with plant essential oil. It has a long life, strong corrosion resistance, compact size, and easy maintenance.

A large-diameter air inlet pipe connected to one of the chambers partitioned by a partition in the air purifier housing and the other chamber in which the deodorizing fragrance is placed. And a small-diameter air outlet pipe that is coaxially inserted into the air inlet pipe and has its end opening communicated with the other chamber in which the deodorant fragrance is arranged through the partition wall together in the exhaust system passage. Due to the two-layer pipe structure facing, a pressure difference based on the difference in flow velocity density is generated between the air blowing port pipe and the air blowing port pipe, and the deodorant fragrance is sucked from the air blowing port pipe in the chamber. A turbulent flow that enhances the contact efficiency between the odorous component and the deodorizing fragrance is generated, and clean air is forcibly discharged from the air outlet pipe on the negative pressure side into the pipe system passage.
