Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building of an oil plant that collects oil by converting plastic into oil.
[0002]
[Prior Art and Problems to be Solved by the Invention]
At present, there are about three large-scale oil refinery plants in Japan that convert waste plastics into oil, and small-scale oil refinery plants are currently being developed. In these oil production plants, when vinyl chloride is treated, toxic gases such as hydrogen chloride gas and dioxin are generated, and measures for these are necessary, but at present these measures are insufficient. It was.
[0003]
[Means for Solving the Problems]
Therefore, the present invention is characterized in that the building that houses the small oil plant has been photocatalyzed.
[0004]
For this photocatalyst treatment, use a vent plug with a photocatalyst attached, a hanging film with a photocatalyst attached from the ceiling, a photocatalyst tube at the tip of the chimney, a photocatalyst tile on the floor surface, A photocatalyst box is provided.
This deodorizes the air in the building and decomposes harmful gases such as dioxins.
[0005]
Embodiment
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0006]
In FIG. 1, a small oil refinery plant body 1 is housed in a building 2, and this oil refinery plant 1 is for collecting plastic such as waste plastic as the original oil. The building 2, which has a small size of about 5 m and a height of about 5 m, includes a roof 2 a, side walls 2 b, and a floor surface 2 c. At the apex of the roof 2a, a plurality of ventilation plugs 3 are provided in the vertical direction of the building at predetermined intervals, and a photocatalyst box 4 is provided on the side wall 2b of the building.
[0007]
As shown in FIG. 2, the oil purification plant main body 1 has a hopper 5, and plastic crushed to 1 to 2 m square by a crusher 7 is supplied to the hopper 5 via a conveyor C, and the crusher 6 The raw material plastic is put in by the conveyor C2.
In the vicinity of the crusher 6, there is provided a mounting place 10 on which raw material plastic carried from the inlet 8 is placed. The placement site 10 may emit a bad odor when processing waste plastic, but a photocatalytic tile 11 is laid at least on the floor surface near the placement site 10 in order to deodorize the bad odor. This photocatalyst tile 11 is formed by forming a photocatalyst layer made of fine particles such as titanium oxide and aluminum oxide on the top surface of the tile by thermal spraying, and has a great deodorizing effect. A photocatalytic tile may be laid on the entire floor surface.
[0008]
From the roof 2a of the building 2, as shown in FIG. 1, sagging films 12,... 12 hang down at a predetermined interval, and the sagging film 12 is formed of a nonwoven fabric made of plastic fibers. A photocatalyst is attached. The banner 12 may be a metal plate or a wood plate as long as the photocatalyst can be attached thereto, regardless of its material.
When processing vinyl chloride containing chlorine in an oil production plant, hydrogen chloride gas and dioxin may be generated, so countermeasures are essential. Since hydrogen chloride gas is likely to be generated and leaked in the vicinity of the dechlorination apparatus provided in the vicinity of the hopper 5 in FIG. 2, exhaust fans 13,... In case of a leak. Since hydrogen chloride gas is heavier than air, it stays near the floor surface, and the exhaust fan 13 is provided near the floor surface to discharge the hydrogen chloride gas.
[0009]
As shown in FIG. 3, the ventilation plug 3 includes a rotating fan 21 in a cylinder 20, and the upper surface of the cylinder 20 is covered with a roof plate 22. The rotary fan 21 includes blades 23 and 22, which are attached to a shaft 24. The shaft 24 is rotated by a motor 25, and the upper and lower ends of the shaft 24 are supported by radial support frames 26. It is supported. The air in the building flows in the direction of arrow A in the case of the exhaust vent plug, and in the reverse direction in the case of the suction vent plug. A plurality of ventilation plugs 3 may be provided, a part of which is a discharge ventilation plug, and the rest may be configured as an intake ventilation plug.
[0010]
Note that the photocatalyst is attached to the entire inner surface of the vent plug 3 by thermal spraying. In particular, if the photocatalyst is attached to the blade 23 of the rotary fan 21, the blade 23 rotates to increase the contact area with the air. This significantly increases the effect of the photocatalyst. In addition, a high voltage generator (transformer) 27 is connected to the cylinder 20, and the ventilation plug 3 is electrically insulated and installed on the roof, so that the entire ventilation plug 3 becomes an electric field atmosphere. As a result, the photocatalyst is excited, and the effect of the photocatalyst is further remarkably increased.
[0011]
As shown in FIG. 4, a dioxin decomposition cylinder 30 is provided at the tip of the chimney 28 extending from a hot air generator that supplies a heat source for the oil plant, and the decomposition cylinder 30 is supported on the upper side wall of the building 2. 31 and baffle plates 32, 32... 32 arranged in a staggered manner in the main body casing 31, and the combustion gas entering from the inlet 33 is discharged from the outlet 34 into the atmosphere while hitting the baffle plate 32. A photocatalyst layer is formed by thermal spraying on the inner wall of the main body casing 31 and the baffle plate 32, and a high voltage generator 35 is connected to the main body casing 31, whereby the inside of the dioxin decomposition cylinder 30 is made an electric field atmosphere. The dioxin decomposition ability of the photocatalyst is improved. The disassembly cylinder 30 is electrically insulated by being connected to the chimney 28 via an insulator 36 and supported on the side wall 26 of the building 2 via an insulator 37.
[0012]
The photocatalyst box 4 attached to an appropriate position on the side wall 2b of the building has a box 40 as shown in FIG. 5, and an air inlet 41 is formed on the lower surface of the box 40, and a fan 42 is formed on the upper surface thereof. Is provided. Guide plates 43, 43 are erected inside the box body 40, and the back surface of the box body 40 faces a ventilation port 44 provided on the side wall 2b of the building. The outer wall and inner wall of the box 40, as well as the photocatalyst layer formed by thermal spraying or paint, may be formed on the guide plate 41 and the fan 42, and an electric field atmosphere may be formed by installing a high voltage generator if necessary. In the photocatalyst box 4, the air in the building sucked from the lower surface of the photocatalyst box 4 is deodorized by the photocatalyst and a part of the dioxin is also decomposed.
