Description

[Technical field]

[0001] The present invention relates to a combustible incineration facility and an incineration method for placing and incinerating combustible materials such as grass and trees. [Background technology]

[0002] In the conventional maintenance and management of rivers and roads, weeds on the slopes of embankments and roadsides were cut, dried on the spot, and then raked into strips on the ground at the top of the slopes, where they were incinerated. However, this method of incinerating weeds and other materials was difficult to completely burn because it was done on the ground. As a result, there were cases where a lot of smoke was generated, obstructing the visibility of drivers of vehicles traveling on the roads on the embankments or on general roads, and smoke was blown to nearby houses, causing ashes to splash on laundry, resulting in complaints. In order to prevent such complaints from third parties, a method has been adopted in which the grass clippings are transported to a place where they are less likely to affect third parties, piled up, and then incinerated. However, because the grass clippings are piled up on the ground and incinerated, there are problems in that the combustion temperature is difficult to increase due to the influence of the dampness of the ground and the difficulty in supplying oxygen to the burning area, so a lot of smoke is still generated and a long burning time is required.

[0003] In order to solve these problems, the inventor proposed a "Combustible Incineration Equipment and Incineration Method" that has a combustible incineration rack with a space at the bottom and an air injection member in the space at the bottom of the combustible incineration rack. However, although the combustion temperature exceeded 900 degrees by forcibly injecting compressed air from the bottom of the incineration rack into the combustion part, and the efficiency of the incineration work improved, the air injection member at the bottom of the combustible incineration rack melted or bent due to the high temperature, and it had to be replaced many times.

[0004] [Patent Document 1] JP 2016-138673 A Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above problems, the present invention aims to provide a combustible incineration facility and incineration method that uses an air injection device that can be placed at any position around the combustible incineration rack instead of the air injection device provided at the bottom of the combustible incineration rack to inject compressed air into the burning part of the combustible, in order to eliminate the need to repeatedly replace the air injection member that melts or bends due to high temperatures, and to continue to reduce smoke generation and enable incineration work to be completed in a short time.Furthermore, the air injection device is a device that can be operated by remote control, and is mounted on a self-propelled vehicle that can be operated by a remote control device, so that the operator who operates the backhoe can work on it from the driver's seat. [Means for solving the problem]

[0006] The combustible incineration equipment according to the present invention is provided with a combustible incineration rack having a combustible incineration rack surface formed on a flat surface with a space provided between the combustible incineration rack surface and a plurality of rod-shaped members made of steel or heat-resistant members arranged in parallel and fixed thereto, and a left and right inclined rack portion arranged in a V shape so that both sides of the combustible incineration rack surface are expanded upward. The rod-shaped members of the left and right inclined rack parts are at least one of sliding, folding and detachable, or any combination of these, so that the protruding length can be adjusted. Also, the incineration rack is characterized by the use of an air injection device that can be placed at any position around the incineration rack and forcibly injects air or heated air toward the combustible part to incinerate the combustible material at high temperature and high speed.

[0007] By adopting such a configuration, it is possible to prevent the air injection device from melting or bending due to high temperatures. In addition, a bright heater capable of injecting hot air or a direct-fire jet heater that directly blows the heat of a burner with a fan can also be used as the air injection device in this case. By blowing such hot air, it is possible to promote drying of the grass clippings and improve combustion efficiency.

[0008] In addition, the combustible incineration equipment according to the present invention may be characterized in that one or more air direction control plates are provided in the space below the combustible incineration rack to change the direction of the air injected from the air injection device toward the combustion section above. By efficiently directing the air toward combustible materials such as grass clippings, the combustion efficiency can be improved.

[0009] Furthermore, in the combustible material incineration equipment of the present invention, a wind direction control plate may be provided around the space below the combustible material incineration stand, except for the air inlet from the air injection device, in order to change the direction of the air flow injected from the air injection device toward the upper combustion section.

[0010] Furthermore, in the combustible material incineration equipment of the present invention, one or more wind direction control plates are provided in the space below the combustible material incineration stand for changing the direction of the air flow sprayed from the air injection device toward the combustion section above, and the equipment may be characterized by having an ashtray section capable of collecting ashes that fall from the combustible material and a wind direction control device having a handle section that can be freely inserted and removed from the space.

[0011] Furthermore, in the combustible incineration equipment according to the present invention, a combustible drying rack for drying wet combustibles is provided above or to the side of the combustible incineration rack, or both. The combustible material drying apparatus may further include an air injection device disposed around the combustible material drying rack for forcibly injecting heated air toward the moist combustible material.

[0012] Furthermore, in the combustible incineration facility according to the present invention, the air injection device may be operable by a remote control device. In addition, in the combustible incineration facility according to the present invention, the air injection device may be mounted on a self-propelled vehicle that can be operated by a remote control device. In this way, when the air injection device and the self-propelled transport vehicle are remotely operable, it becomes possible to approach places with relatively high temperatures. For example, a backhoe operator can operate the air injection device and the transport vehicle equipped with it while remaining on the backhoe.

[0013] Furthermore, the present invention provides a method for incinerating combustible materials, which is characterized by using the above-mentioned combustible material incineration facility. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the embodiment and drawings described below are intended to exemplify a part of the embodiment of the present invention, and are not intended to be used for the purpose of limiting the configuration of the embodiment. In addition, the same or similar reference numerals are used to designate corresponding components in each drawing.

[0016] (First embodiment) As shown in FIG. 1, the combustible material incineration equipment 100 according to the first embodiment mainly comprises a combustible material incineration stand 30 consisting of a flat combustible material incineration stand surface 10, left and right inclined stand sections 20 arranged in a roughly V-shape so as to extend upward on both sides of the combustible material incineration stand surface 10 in a side view, and an air injection device 40 for injecting air.

[0017] The combustible incineration rack surface 10 is formed on a horizontal surface with multiple gaps formed in which multiple steel materials 12 are arranged in parallel or in a lattice pattern at intervals. The intervals between the steel materials 12 are preferably 20 cm to 50 cm. If the intervals are too narrow, the combustible incineration equipment becomes too heavy, and if the gaps are too wide, grass clippings cannot be held on the upper surface. There is no limitation on the steel materials 12 used, and any form of steel material 12 may be used. The combustible incineration rack surface 10 is preferably supported at a height of about 50 cm to 100 cm from the ground.

[0018] As shown in FIG. 2, the left and right inclined frame parts 20 are arranged on both sides of the combustible incineration frame surface 10 so that the upper interval is wider and the lower interval is narrower in side view. The left and right inclined frame parts 20 are composed of a lower side rod-shaped member 23b having a hollow insertion hole 23a and an upper side rod-shaped member 23c that can be inserted into the insertion hole 23a of the lower side rod-shaped member 23b. By configuring in this way, the upper side rod-shaped members 23c can be attached and detached one by one to the insertion hole 23a of the lower side rod-shaped member 23b, and the protruding length of the rod-shaped member 23 of the left and right inclined frame parts 20 can be adjusted by attaching and detaching them. Since one of the upper side rod-shaped members 23c is lightweight, it can be freely attached and detached by human power. Therefore, after the combustible incineration frame surface 10 is installed in a predetermined position by a crane, the left and right inclined frame parts 20 can be attached only by human power, and the combustible incineration equipment 100 can be completed.

[0019] As another embodiment of the method for adjusting the length of the rod-shaped member 23 of the left and right inclined stand section 20, as shown in Fig. 3, the upper rod-shaped member 23c is formed to be slidable relative to the lower rod-shaped member 23b having a hollow insertion hole 23a, and the slide fixing pin 24 is inserted into the fixing hole 24a formed in the lower rod-shaped member 23b and the upper rod-shaped member 23c to fix it to a predetermined protruding amount. In this way, by providing the upper rod-shaped member 23c to be slidable downward, the protruding amount of the upper rod-shaped member 23c can be reduced. As a result, the width of the combustible incineration equipment 100 is narrowed, so that the loading area on the transport vehicle can be narrowed.

[0020] Furthermore, as shown in Fig. 4, a hinge 25 may be provided between the lower rod-shaped member 23b and the upper rod-shaped member 23c, so that the upper rod-shaped member 23c can be formed to be foldable relative to the lower rod-shaped member 23b. By folding it in this way, the amount of protrusion of the upper rod-shaped member 23c can be reduced. This narrows the width of the combustible waste incineration equipment 100, so that a smaller loading area is required on a transport vehicle.

[0021] It is also possible to use any combination of the removable rod-shaped member 23, the slidable rod-shaped member 23, and the foldable rod-shaped member 23. For example, the rod-shaped member 23 may be formed to be foldable, and the upper rod-shaped member 23c may be provided to be removable.

[0022] As shown in Fig. 1, the air injection device 40 has one or more air injection ports 45, and injects air from a compressor (not shown) from the air injection ports 45. At this time, it is advisable to use a bright heater capable of injecting hot air or a direct-fire jet heater that directly blows the heat of a burner with a fan. The air injection device 40 is arranged around the combustible material incineration rack 30, and forcibly injects air or heated air toward the combustible material burning portion of the combustible material incineration rack surface 10.

[0023] As shown in Fig. 5, in order to effectively direct the airflow of the air or heated air injected from the air injection device 40 toward the combustible materials, one or more wind direction control plates 43 may be provided in the space α below the combustible incineration rack 30 to change the wind direction toward the upper combustion section (above the combustible incineration rack surface 10 on which the combustible materials are placed). The wind direction control plate 43 should be designed so that the area on which the wind collides gradually increases from the air injection device 40 side toward the rear side. By providing the wind in this way, it is possible to blow the wind with an average strength against the combustible incineration rack surface 10.

[0024] As shown in Fig. 6, a wind direction control plate 43 may be provided around the space α under the combustible incineration rack 30, except for the air inlet 46 from the air injector 40, as a method of changing the wind direction of the air flow injected from the air injector 40 toward the combustible burning part above. By covering the periphery with the wind direction control plate 43 in this way, heat is less likely to escape to the surroundings, and heated air can be effectively applied to the combustibles. The air inlet 46 may be provided by using the short side as shown in Fig. 6, or by cutting out a part of the long side as shown in Fig. 7.

[0025] Furthermore, as shown in Fig. 8, as a method of changing the wind direction of the airflow injected from the air injection device 40 around the space α under the combustible incineration rack 30 toward the combustible burning part above, a tall wind direction control plate 43 may be used to surround not only the space α but also the combustible burning part above it. By covering the combustion part with the wind direction control plate 43 in this way, heat is less likely to escape to the surroundings, and heated air can be effectively applied to the combustibles. Furthermore, scattering of ashes from the combustion material can be prevented.

[0026] Furthermore, as shown in Fig. 9, in order to prevent the hot air from the air injection device 40 from scattering to areas other than the space α under the combustible incineration rack 30, a pipe member 48 that communicates from the air injection device 40 to the space α may be used to seal everything except the air inflow member 46 and prevent air from leaking from the air injection device 40 to the space α. By adopting such a configuration, it is possible to prevent heat from escaping before the air flows into the air inflow section 46, and to effectively apply the heated air to the combustibles. Furthermore, it is possible to prevent the ashes of the combustion material from scattering.

[0027] Furthermore, as shown in FIG. 10, a wind direction control device 50 may be placed in the space α below the combustible incineration rack 30. The wind direction control device 50 is generally box-shaped and functions as an ashtray that can receive ashes from combustion materials burned above. Furthermore, one or more wind direction control plates 53 are provided to change the wind direction of the air flow injected from the air injection device 40 toward the combustion part above. The wind direction control device 50 is provided with a gripping part 56 that can be freely inserted and removed from the space α. Therefore, if there is a combustible incineration facility 100 that is formed so as to be freely inserted and removed from the space α and has the space α below, the wind direction of the air can be easily controlled.

[0028] Furthermore, as shown in FIG. 11, a combustible drying rack 70 for drying wet combustible materials may be provided above or to the side of the combustible incineration rack 30, or both. If the combustible drying rack 70 is provided above the combustible incineration rack 30, the wet combustible materials can be dried by the heat during combustion. If the combustible drying rack 70 is provided on the side, an air injection device 40 for forcibly injecting heated air toward the wet combustible materials may be provided around the combustible drying rack 70. By adopting such a configuration, the combustible materials can be dried before the main combustion is performed by the combustible incineration rack 30, so that the combustible materials can be effectively burned. The air injection device 40 in this case may be shared between the combustible drying rack 70 and the combustible incineration rack 30, or may be provided separately.

[0029] Furthermore, the air injection device 40 may be provided so that it can be started / stopped, and its wind direction and wind power can be adjusted and moved by a remote control device. The air injection device 40 may also be mounted on a self-propelled vehicle that can be operated by a remote control device. By making it operable by such a remote control device, the air injection device 40 can be placed closer to the combustible material incineration rack 30, and the backhoe operator can operate the combustible material, thereby reducing the number of people required.

[0030] The combustible incineration equipment 100 constructed as described above is used as follows. First, the combustible incineration rack surface 10 is installed at the place where incineration is to be performed by heavy machinery or a crane. Then, the upper rod-shaped members 23c are manually inserted one by one into the insertion holes 13a of the lower rod-shaped members 23b constituting the left and right inclined rack parts 20 formed by bending so as to communicate with the parallel rod-shaped members 23 that form the combustible incineration rack surface 10, thereby fabricating the left and right inclined rack parts 20, and the combustible incineration equipment 100 is completed. Combustible materials such as grass clippings are placed on the combustible incineration rack surface 10 and the left and right inclined rack parts 20 of the assembled combustible incineration equipment 100 using heavy machinery or the like. Then, at the same time as the combustible materials are ignited, air or heated air is forcibly injected from the air injection port 45 of the air injection device 40 toward the combustion part of the combustible materials. By injecting air into the combustion part, oxygen is supplied to the combustion part, and the combustion effect is greatly improved.

[0031] According to the combustible material incineration equipment 100 of the present invention, an air injection device 40 is provided for the purpose of forcibly supplying air or heated air (oxygen) from the combustible material incineration platform surface 10 to the combustible material burning section by an injection method. This further promotes combustion in the burning section and increases the combustion temperature, thereby achieving complete combustion and greatly reducing the generation of smoke, and also greatly accelerating the incineration speed.

[0032] The present invention is not limited to the above-described embodiments, and may be embodied in various forms within the technical scope of the present invention.

[0033] As shown in the above-mentioned embodiment, the present invention can be used as an incineration facility. [Explanation of symbols]
