Technical background

  In general, a deodorizing filter effective for deodorizing exhaust gas containing oil generated from kitchens and food processing plants in restaurants and restaurants is made of ceramic powder material and titanium oxide, manganese oxide, copper oxide or Powder material consisting of a honeycomb-type deodorizing unit or ceramics that has a plurality of through-holes kneaded with a binder and water in a catalyst having an adsorption / decomposition function such as a zinc compound and divided by porous partition walls in an injection molding machine A honeycomb structure having a plurality of through-holes that are kneaded by adding a binder and water to each other and partitioned by a porous partition wall by an injection molding machine, titanium oxide, manganese oxide, copper oxide, zinc compound and binder component Honeycomb type deodorizing unit with a catalyst layer with adsorption function consisting of It is known.

  These honeycomb-type deodorizing units use a necessary number of deodorizing units in accordance with the amount of processing air of the kitchen exhaust gas in order to achieve sufficient catalytic decomposition of the kitchen exhaust gas and the deodorizing unit. For example, W150mm × H150mm × L200mm size honeycomb type deodorizing unit is packed in 2 blocks, 2 columns, 2 columns, 3 columns, 3 columns, 2 columns, 3 columns, 3 blocks, and attached to the deodorizing filter casing. There is known a deodorizing filter which is set in a frame and exhaust gas generated from a kitchen or food processing plant is passed through the deodorizing unit to remove odorous components in the exhaust gas and exhaust it as clean air.

  Then, as a method of collecting the honeycomb type deodorizing unit into a block body in two rows, two rows, two rows, three rows, three rows, two rows, and three rows, three rows, the deodorizing unit is placed in the recessed portion of the zinc iron plate, and the zinc iron plate is The cover is covered with a block body.

  For this reason, the block fixing of the filter is weak and may be displaced by vibration, and the dent-like zinc iron plate and lid used for the block body are costly, resulting in an increase in the cost of the deodorizing filter. There was concern. Furthermore, there is a problem that the work for assembling the block body takes time, and when the block body is pushed into the filter frame, the corners of the block body are caught and the weight increases, so that the work is troublesome.

Problems to be solved by the invention

  Accordingly, the present invention is intended to solve the above-mentioned problems, and a first object of the present invention is to reduce the cost of a block body in which deodorizing units are combined.

  The second object of the present invention is that the block body in which the deodorizing unit is assembled is compact and increases the unity of the block body, and it is lightweight and can be easily and smoothly set on the filter frame in the casing. It is a thing.

Means for Solving the Invention

  The first solving means of the present invention is characterized in that an appropriate number of deodorizing units are wound with a single PVC adhesive sheet to form a block body.

  Here, as a single adhesive sheet, a flame retardant nonwoven fabric, an aluminum adhesive tape, a polyester resin sheet, a polyethylene resin sheet, a vinyl chloride resin sheet, or other appropriate material is used.

  The operation of the problem solving means is as follows. In other words, on a single adhesive sheet, the required number of deodorizing units are combined and placed in a substantially square shape, and are stacked and fixed with a sheet adhesive to form a block body. In comparison, the degree of adhesion fixation is increased, the workability is improved, the cost is further reduced, and the cost of the deodorizing filter is reduced.

  Furthermore, since the deodorizing unit is blocked by a single lightweight adhesive sheet, it is compact and can be easily and smoothly attached to the filter frame in the casing.

The invention's effect

As described above, the deodorizing filter of the present invention has the following effects.
(1) High deodorization and oil decomposition effects can be obtained by the action of both odor gas, oil adsorption and catalytic decomposition.
(2) Not only adsorbs and captures odorous substances such as activated carbon, but also oxidizes and decomposes them by catalysis to release them into the atmosphere as odorless and low odor components, enabling continuous use over a long period of time. In addition, the deodorizing performance does not drop sharply.
(3) Since the honeycomb structure is used, efficient contact with the kitchen exhaust necessary for adsorption / decomposition and low pressure loss are possible.
(4) Since the deodorizing unit is blocked with a single adhesive sheet that is inexpensive and easy to handle, the cost of the deodorizing filter can be reduced.
(5) Since the deodorizing unit is made into a block with a single lightweight and weather-resistant adhesive sheet, the contact solids are made more compact and can be easily and smoothly attached to the casing frame.
