Description

  The present invention relates to a batch-type deodorizing apparatus.

  In recent years, many treatment apparatuses and fermentation apparatuses have been developed for fermenting and decomposing organic wastes such as food waste and livestock manure to make them compost or to reduce their weight. In the process of composting and reducing the amount of organic matter, various unpleasant odors are generated by fermentation and decomposition of the organic waste itself as well as the odor of the organic waste itself. For this reason, a deodorizing material is incorporated in these processing apparatuses or used in connection with the deodorizing apparatus.

For example, in Patent Document 1, a ventilation fan is attached to the upper part of a treatment tank of a garbage disposal machine, and bamboo charcoal powder as a deodorizing material is packed in a small bag at the exhaust port of the ventilation fan and arranged inside a deodorization box. A deodorizing device is described in which is connected to a deodorizing box. However, a large amount of water is generated during fermentation and decomposition of organic waste, especially food waste, and the bad odor containing this water or water vapor also flows into the deodorizing device and reduces the deodorizing function of the deodorizing material. In the treatment of garbage, the efficiency of use of the deodorizing device is such that the deodorizing device has a rapid decline in efficiency, and it is necessary to replace or regenerate degraded deodorizing materials, and during that time it is necessary to stop the deodorizing device. Decreases.

  In the present invention, it is possible to regenerate / replace deteriorated deodorizing material without stopping the deodorizing device, and therefore, to provide a deodorizing device that does not deteriorate the deodorizing function of the deodorizing device and is easy to manage the device. Let it be an issue.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor has come up with a batch-type deodorizing apparatus in which at least two deodorizing cylinders containing deodorizing materials arranged in the deodorizing apparatus are provided in parallel. That is, when the deodorizing function of one deodorizing cylinder deteriorates, the odor passage to the deodorizing cylinder is closed, the odor passage is guided to the other deodorizing cylinder, and the odor passage is closed in the meantime. Eliminates the need to stop the operation of the deodorization device by ventilating the outside air to dry the deodorant or regenerating after removing the cause of deterioration, so that the deodorization device does not deteriorate the deodorization function of the deodorization device The present invention has been found.

  That is, the present invention has a dust collection part, a deodorization cylinder containing a deodorizing material, and an exhaust part, and the introduced odor is deodorized by removing dust from the dust collection part and passing through the deodorization cylinder. After that, in the batch type deodorizing apparatus to be exhausted, at least two of the deodorizing cylinders are provided in parallel, a window is provided on the wall of the odor passage introduced into the deodorizing cylinder, and at the same time the odor passage is switched to the window portion. There is provided a batch type deodorizing device characterized in that a switching means for switching between ventilation and blocking of outside air is provided, and deodorized air that has passed through each deodorizing cylinder and outside air are merged in an exhaust section and then exhausted.

  According to the present invention, at least two deodorizing cylinders are provided in parallel, and by providing a switching means capable of switching the odor path that can be opened and closed for each deodorizing cylinder and changing the odor path to each deodorizing cylinder, The deodorizing operation can be continued by closing the odor passage to the deodorizing cylinder containing the deodorized material and opening the odor passage to the deodorizing cylinder containing the new or recovered deodorizing material. it can. The switching means switches between the ventilation and blocking of the outside air simultaneously with the switching of the odor passage, and the deodorization function is regenerated and recovered by allowing the outside air to pass through the deodorizing cylinder with the odor passage closed and drying the deodorizing material. Can be made. The deodorized air that has been deodorized and has a reduced odor is combined with the outside air that has passed through the other deodorizing cylinder at the exhaust section. it can. In addition, if there is a cause of deterioration other than moisture, the deodorizing material that has been stored in a deodorizing cylinder whose odor passage is closed and has a deodorizing function that has deteriorated can be removed by removing the cause of the deodorizing deterioration while the outside air is vented. Can be played. The deodorizing apparatus of the present invention can be particularly suitably used for deodorizing a garbage disposal machine that generates a large amount of moisture.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 shows an example of a batch type deodorizing apparatus of the present invention connected to a garbage disposal apparatus, and is a cross-sectional conceptual diagram illustrating the structure of the apparatus and the flow of odors. In FIG. 1, 1 is a dust collection box, 2 is a pipe which is an odor passage, 3, 3 'is a deodorizing cylinder, 4 is an exhaust pipe, and 5 is a switching bumper.

  The odor generated in the garbage processing apparatus is introduced into the dust collection box 1, dust and the like mixed while passing through the box are removed, and enters the deodorizing cylinder 3 through the odor passage 2. In the batch type deodorizing apparatus of the present invention, at least two deodorizing cylinders 3 are arranged in parallel, and odor enters one of the deodorizing cylinders 3 and is deodorized there. The deodorized air (deodorized air) exits the deodorizing cylinder and is exhausted through the exhaust unit 4. The odor passage 2 is provided with a switching damper 5 which is a switching means for forming an odor passage leading to one of two or more deodorizing cylinders. Since two or more deodorizing cylinders 3 are arranged in parallel, the odor passage 2 can be switched and continuously operated.

A window is provided in the odor passage so that outside air can be taken in through the window, and the switching damper 5 performs the intake and shut-off of the outside air simultaneously with the switching of the odor passage. The switching means 5 is not limited to a damper, and may be a slide plate as long as it has a structure capable of simultaneously switching the odor passage and venting / blocking outside air. By providing a slide plate in each of the odor passage and the window portion, the switching can be performed simultaneously by interlocking them. A valve that can be switched in a plurality of directions, such as a three-way valve and a four-way valve, can also be used. These switching means 5 can measure the deterioration time of the deodorizing cylinder 3 in advance, and can switch the odor passage and the outside air window at the same time by using a timer set in accordance therewith. Further, by providing forced air circulation means such as a fan at an appropriate position in the downstream portion of the batch-type deodorizing apparatus, it is possible to smoothly distribute the odor and the outside air.

  The operation or operation method of the batch type deodorizing device of the present invention will be described. When the deodorizing cylinder 3 connected to the open odor passage is opened by the switching damper 5 for switching the odor passage 2 being deodorized. In the deodorizing cylinder 3 ′ other than the deodorizing cylinder 3, the odor passage is closed by the damper, the outside air window is opened, and the ventilation state is established. After the outside air passes through the deodorizing cylinder 3 ′, it enters the exhaust section 4 and enters the deodorizing cylinder 3. It is exhausted after merging with deodorized air that has passed through. Accordingly, at any time, any one deodorizing cylinder 3 can be in an operating state, while the other deodorizing cylinder 3 ′ is operated for ventilation or odor in order to dry the moisture and regenerate the deodorizing function. A heater can be provided near the top of the deodorizing cylinder in the passage or in the vicinity of the inlet of the deodorizing cylinder to perform heating air blowing.

  In addition, when the deodorizing material stored in the deodorizing cylinder 3 'has deteriorated for reasons other than moisture, the deodorizing function is regenerated and restored by removing the cause of the deodorizing material deterioration during the ventilation operation. Can be recovered. The regeneration and restoration of the deodorizing function is called maintenance. Examples of the main causes of deterioration of deodorizing materials other than moisture include, for example, oil films such as fats and oils, and adhesion of organic substances. Examples of the method include washing with an alkali, an aqueous solution thereof, or an alcohol or an aqueous solution thereof. Moreover, it may be dissolved with hot air or removed by incineration. Even during these maintenance operations, the deodorizing apparatus does not need to be stopped and can be operated continuously, and the deodorizing function does not deteriorate.

The deodorizing cylinder 3 ′ containing the deodorized material that has been restored to its function by removing the cause of deterioration and accommodated the regenerated deodorizing material is ventilated until the time set by the timer, and waits until the odor passage is opened by the switching damper 5. . Since the outside air exhausted through the deodorizing cylinder 3 'during standby merges with the deodorized air in the exhaust unit 4, if there is a residual odor in the deodorized air, the odor is diluted and the deodorizing device is deodorized. The effect can be improved.

  As the deodorizing material used in the batch-type deodorizing apparatus of the present invention, any type of deodorizing material such as an adsorption type and a decomposition type can be used. . Examples of such a deodorizing material include a filter medium made of nonwoven fabric, paper, ceramic, plastic, etc., which uses a catalyst for decomposing odor components as a deodorizing agent and is coated on the surface with these deodorizing agents.

  In FIG. 1, an example of a batch type deodorizing apparatus having two deodorizing cylinders 3 in parallel is shown. However, in the present invention, the number of deodorizing cylinders 3 is not limited to two, and any number of two or more deodorizing cylinders in parallel can be used. Good. When there are three or more, one deodorization cylinder can be used for deodorization, the other one can be used for maintenance, and the other one is waiting for use, and the other is for maintenance. .

  The batch-type deodorization device of the present invention is a garbage processing device, a processing odor discharged from a food processing factory, an oily odor at a fishery and meat processing factory, an odor generated at a wastewater treatment facility, and an odor generated at an industrial waste treatment facility. It can be used to deodorize all kinds of odors, such as odors generated at machining plants, odors generated from painting work, odors in nursing homes, tobacco odors, and volatile organic compound (VOC) odors. It can be suitably used for deodorization of garbage processing equipment that often generates moisture-containing odors through or fermentation treatment.

It is the conceptual diagram of the cross section explaining the structure of this apparatus and an odor flow which show an example of the batch type deodorizing apparatus of this invention connected with the garbage processing apparatus.
