Abstract
Description
[Technical field]
[0001] The present invention relates to an incineration apparatus for waste oils and fats such as waste oil, waste solvents, and waste resins. [Background technology]
[0002] Used waste oils, waste solvents, waste resins, and other waste oils and fats are sometimes stored in can containers such as drums and round cans. In such cases, a can tipping device has been used to hold and tip the can container so that the contents of the can container flow out or fall into the incinerator through the opening at the top of the can container.
[0003] For example, the applicant has proposed a technology to promote combustion by tipping a drum downward into the incinerator, thereby stirring the contents on the hearth as they are dumped onto the hearth (Patent Document 1).
[0004] However, many types of waste oils and fats have a high calorific value when burned. In such a case, if a large amount of material was put into the incinerator at once, explosive combustion could occur, causing the temperature inside the incinerator to become abnormally high. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Patent No. 5480019 Summary of the Invention [Problem to be solved by the invention]
[0006] An object of the present invention is to provide an incineration apparatus for waste oils and fats that can safely incinerate even highly combustible waste oils and fats. [Means for solving the problem]
[0007] The incineration apparatus for waste oils and fats of the present invention is characterized in that the waste oils and fats are stored in can containers, the apparatus has a tipping device that holds the can containers and tips them toward the incinerator, the tipping device has a means for controlling the tipping angle, and has a temperature measuring means for measuring the temperature inside the incinerator, and the tipping angle is controlled in accordance with the temperature inside the incinerator measured by the temperature measuring means.
[0008] Here, "tilting" refers to the process in which the can container is held upright and then the top of the can container gradually tilts toward the inside of the incinerator, causing the contents to flow out or fall into the incinerator through the opening at the top of the can container, and then the can container is tilted again to a horizontal position so that the top opening faces downward. The tilt angle is the angle at which the can container is tilted.
[0009] Therefore, the purpose of controlling the tilt angle of the can container is to control the amount of contents that flows out or falls from the top of the can container into the incinerator. For example, the speed at which the falling angle reaches angle θ1, the speed at which the falling angle reaches the next angle θ2, etc. are preset, and when the temperature inside the incinerator becomes too high, the falling is stopped or the falling speed is slowed down, etc.
[0010] When the can container has a lid, an opening is provided at the top by removing the lid. Some drums and round cans have removable tops, while others cannot be opened unless the top is cut off. Regardless of the type of can container, it is sufficient as long as an opening can be formed at the top. Effect of the Invention
[0011] In the waste oil and fat incineration device of the present invention, the amount of material fed into the incinerator can be controlled to match the temperature inside the incinerator by controlling the angle at which the can container is tilted, thereby preventing the temperature inside the furnace from becoming abnormally high and allowing the amount of material fed in to be increased when the temperature is low, thereby enabling stable incineration processing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] An example of the configuration of an incineration apparatus for waste oils and fats according to the present invention will be described below with reference to the drawings, but the present invention is not limited to this embodiment.
[0014] FIG. 1 shows an example of an incineration apparatus 10. The incineration apparatus according to the present invention may be a standalone incinerator for waste oils and fats, but may also be configured to have an inlet for can containers provided through the side wall of a large incinerator for general waste, industrial waste, etc. FIG. 1 shows a schematic representation of an incinerator 11 so that these various incinerators may be included.
[0015] An inner door 13 whose opening and closing is controlled and an outer door 14 whose opening and closing is controlled are provided on the side wall of the incinerator 11, thereby forming an input chamber 15 for the can containers 1 between them, and a tipping device 16 is provided for holding the can containers 1 in this input chamber 15 and performing the tipping operation. In this embodiment, the inner door 13 and the outer door 14 have opening and closing devices 13a and 14a for vertical movement, respectively. The can container 1 is a can container such as a drum can or a round can made of steel or stainless steel. The can may be an open-type can also called a pail can, or a tight-head type can. When loading into loading chamber 15, there are no restrictions on the type of can container, as long as it has an opening at the top. The tipping device 16 has a holding section 16a for the can containers 1 and a shower section 16b for extinguishing the fire. The lowering device 16 also has a control means for controlling the lowering angle.
[0016] When the can container 1 is inserted into the insertion chamber 15, a carry-in device 2 for transporting the can container 1 is provided, but is shown diagrammatically in FIG. Although not shown, a sensor for measuring the temperature inside the furnace 12 is attached thereto.
[0017] Next, the flow of the incineration treatment of waste oils and fats contained in a can container will be described with reference to Figs. As shown in FIG. 2( a ), an outer door 14 of a charging chamber 15 provided on a side wall of an incinerator 11 is opened, and a can container 1 is carried into the charging chamber 15 by a carrying-in device 2 . Next, the outer door 14 is closed as shown in FIG. 2(b), the inner door 13 is opened, and the tipping device 16 is operated as shown in FIG. 2(c) to tilt the can container 1 toward the inside of the incinerator 11. This inclination is expressed as the tilt angle θ. The can container 1 shown in FIG. 2 is an example of an open-type drum can, and in the case of liquid waste oil or the like, it flows out into the furnace 2 along the lower side of the circular opening 1a at the top. Waste oils and fats fed into furnace 2 are burned on the hearth. During this process, the heat of combustion causes the temperature inside the furnace to become very high, and this temperature change can be detected by sensors. In the case of highly combustible waste such as waste oil, if too much is put into the furnace 2, there is a risk of explosive combustion, so it is advisable to gradually increase the tilting angle from θ1 to θ2 slowly, as shown in Figures 2(c) and 3(a). When the contents of the can container 1 become low, the tilt angle θ3 is set to 90° as shown in FIG. 3(b), and the tilt angle θ4 is increased so that the opening 1a of the can container 1 faces downward as shown in FIG. 3(c). At this time, the waste oils and fats remaining in the can container 1 may also ignite. In that case, water or the like is sprayed from the shower section 16b to extinguish the fire, as shown in FIG. 4(b). Thereafter, the outer door is opened as shown in FIG. 4(c), and the can container 1 is carried out of the furnace.
[0018] In the present invention, the combustion state inside the furnace is detected by sensors, and the angle at which the can containers are tilted can be controlled while preventing the inside of the furnace from becoming abnormally hot. [Explanation of symbols]
