Description

  The present invention is a washing tower used for a draft, which is made of polypropylene that does not generate light and beautiful glossy dioxin, and has a mist separator and a demister for protecting activated carbon in the middle of an intrusion passage. The present invention relates to an interposing draft wet and dry combined gas cleaning apparatus.

Conventionally, the cleaning tower body in the gas cleaning device used for this type of draft passes through the filler chamber in a state where it is washed with a shower when passing through the packing material chamber. The effect of filters such as the following activated carbon has been significantly reduced.
In addition, since the constituent materials conventionally used for this type of washing tower mainly use vinyl chloride or the like, there is a problem that dioxins are generated and the environment is remarkably deteriorated.

The present invention has been made in view of the above-mentioned conventional drawbacks, and the main purpose thereof is to form the washing tower body using polypropylene, which is excellent in heat resistance, chemical resistance and corrosion resistance, and Uses a lightweight, glossy and hard synthetic resin with excellent impact resistance and no risk of damage or cracking due to vibration, etc., and has good cutting workability, making it easy to assemble and repair in the field. .
Furthermore, the object of the present invention is to install a mist separator and a demister on the upper part of the shower located in the upper part of the packing material chamber provided inside the main body of the washing tower, thereby drying moisture droplets etc. The activated carbon filter located in is protected from moisture and kept dry.

In order to achieve the above object, in the draft wet and dry combined gas cleaning apparatus of the present invention, the cleaning tower body (1) is formed by molding a hard synthetic resin with an olefin-based resin of polypropylene.
The cleaning tower body (1) is provided with a suction port (2) below the outer peripheral side wall and a discharge port (3) at the upper end.
Further, inside the cleaning tower body (1), a circulation pump (5) is provided from the lower end, and a water tank (6) and a filler material chamber (7) for storing packing are provided on the upper part. A shower (8), a mist separator and a demister (9) are accommodated in the upper part of the filler chamber (7), and a plurality of activated carbon filters (10) (10) are accommodated in the upper part.

Since the present invention is configured as described above, the following effects can be obtained.
Compared to conventional vinyl chloride, the washing tower body uses polypropylene, so the specific gravity is small and light weight, and it has excellent heat resistance, chemical resistance, and corrosion resistance, and cutting workability. In addition to being good, there is an effect that hot jet welding is easy, and since there is no generation of dioxin, there is an effect that is very excellent in the environment.
And since the mist separator and demister provided in the upper part of the shower and the filter packing room provided in the main body of the washing tower are interposed, the water droplets rising from the packing material are removed by drying and the activated carbon is dried. As compared with the conventional one, there is an excellent effect that the effect of the activated carbon can be sufficiently achieved over a long period of time.

  It is the front view which partially disclosed this invention.   It is the vertical side view which similarly disclosed the inside of this invention.   It is the rear view from which a part of the present invention was omitted similarly.   It is a top view of the washing tower body of the present invention.

  In the cleaning tower main body (1), exhaust gas from a draft or the like enters from the suction port (2) (2), and first from the suction port (2) by operating the exhaust air and the switch for circulation pump (14). Exhaust gas containing water droplets entering the filler chamber (7), passing through the interior of the filler chamber (7), filtered and lifted by the internal packing, and intruded into the shower (8) After being drained and dried by a mist separator and a demister (9), it is passed through a plurality of activated carbon filters (10) located above, passed through an upper exhaust fan (11), and discharged from the discharge port (3) into the atmosphere. To be released.

Next, an embodiment of the present invention will be described with reference to the drawings. The cleaning tower body (1) is composed of a hard synthetic resin polypropylene resin, and is formed into a vertical rectangular shape as a whole. The circulation pump (5) and the upper water tank (6) are connected by a drain pipe (16).
Intrusion gas from the suction port (2) passes through the filler chamber (7) and is simultaneously filtered by the upper shower (8).
The exhaust gas cleaned by the shower (8) rises in a state of containing water droplets in the filling, and when it passes through the inside of the mist separator and demister (9) located at the top, the water droplets are removed and dried. Are used simultaneously.
Next, the dried exhaust gas that has passed through the mist separator and demister (9) ascends in the chamber in which the plurality of upper activated carbon filters (10) are arranged in parallel, and the exhaust fan (11) and motor ( It is discharged to the outside through the discharge port (3) installed at the top by the operation of 12).

Reference numeral (14) shown in FIG. 1 and FIG. 3 shows an exhaust fan and a circulation pump switch attached to the side wall of the washing tower main body (1), and reference numeral (15) similarly provided on the side wall shows a valve with a ball tap. It is a thing.
Reference numeral (13) denotes a motor cover of the motor (12).
Next, the code | symbol (17) shown in FIG. 2 shows the water supply and chemical | medical solution inlet provided in the upper part of this water tank (6). Further, an activated carbon for examining the inside of the activated carbon filter (10) and a monitoring observation window (18) are provided, and a shower monitoring window (19) for looking into the room of the shower (8) is installed. Furthermore, it has a structure in which a water level observation window (20) for monitoring the inside of the water supply and chemical solution inlet (17) is installed.
