Description

[Detailed Description of the Invention] The present invention relates to an incinerator for incinerating the fish and shellfish residue produced from the process of treating fish and shellfish residues.

The remains of raw fish or seafood are subjected to a steaming process called kutukar, then pressed and separated into solids and broth.

The solid content is further dried and used as a raw material for fishmeal, and the broth is centrifuged to further separate oil and broth, and the latter broth is concentrated to make fish soripu.

Sulfuric acid is further added to this fish sori pull to extract oil, chemicals, and protein from the fish sori pull,
The remainder is a viscous, miso-like non-liquid substance called futu.

The ash content of this foots is 40.58% moisture and 4.5% ash.
70%, carbohydrates 23.54%, crude protein 2.88%, and crude fat 28.30%.

Although this ingredient ratio is an average value, almost half of the ingredients in foots are carbohydrates and crude fat.

And these foots emit what is called a foul odor.

As described above, the foods containing the above-mentioned components generated in the process of processing fish and shellfish residues have conventionally been mixed with asphalt tar, dumped at sea, or buried in the ground.

However, the method of mixing foots into asphalt cool is not suitable for treating large amounts of foots, and dumping them at sea or burying them in the ground causes pollution.

Businesses that dispose of such foods have attempted to incinerate the foods, but since the foods are extremely difficult to burn, they have failed to completely burn them, resulting in soot and odor caused by incomplete combustion. Due to outbreaks, this method could also cause pollution.

Therefore, an object of the present invention is to provide an incinerator for efficiently and completely burning viscous, non-liquid food produced in the process of processing fish and shellfish residues.

The Hoots incinerator of the present invention will become more apparent from the following description with reference to the accompanying drawings showing preferred embodiments.

As shown in FIGS. 1 and 2, the trays are rectangular tray portions 34 and 36 that are stacked in three tiers at intervals in the vertical or vertical direction by means of support legs 32.
．． 38, the bottom area of the lower tray portion 38 is larger than the bottom area of the middle tray portion 36, and the bottom area of the middle tray portion 36 is larger than the bottom area of the upper tray portion 34. has been done.

That is, the dimensions of the dish portion are uniformly increased as a whole from the top to the bottom.

In addition, the upper tray portion 34 and the middle tray portion 36, excluding the lower tray portion 38, each have a large number of openings 40 in their bottom portions over the entire surface of the bottom portions.

The first combustion chamber 20 within the housing 12 further includes:
In the receiver, a primary burner device 42 that injects a flame toward the pan 30 is attached to the front wall 44 of the housing 12 and arranged.

Also, in the second combustion chamber 22, a secondary burner device 46 that injects flame into the combustion chamber is connected to the housing 12.
It is mounted and arranged on the rear wall 48 of the.

These primary and secondary burner devices 42, 46 are ignited and turned off by a controller (not shown) in response to the internal temperatures of the first combustion chamber 20 and the second combustion chamber 22, respectively. Controlled outage.

The foot 50 to be supplied to the tray 30 disposed in the first combustion chamber 20 is stored in a boot tank 52 installed near the housing 12.

The inside of this foots tank 52 is connected to one end of a feed pipe 56 constituting a foots supply means via a pump 54 for feeding foots, and the other end 58 of the feed pipe is connected to the housing 1.
2, the receiver is arranged so as to open above the plate 30.

A foots feed adjustment valve 60 is installed in the middle of the feed pipe 56 for adjusting the amount of foots to be fed onto the upper tray portion 34 of the tray 30.

An opening (not shown) for supplying air for combustion into the first combustion chamber 20 is provided at a suitable location in the wall portion of the housing 12 surrounding the first combustion chamber 20; 2
The rear wall of the housing 12 surrounding the combustion chamber 22 has a second
A smoke conduit 62 communicating with the combustion chamber 22 is attached, and the smoke conduit is connected to a chimney 64.

The foots splash prevention device 66 includes a head, a slope connected to the head and sloped outward, an open bottom, and openings provided at equal intervals in the circumferential direction on the slope in the vicinity of the bottom. 68 and an open lower cone 0 provided at the head, and is attached to the center of the upper surface of the upper plate portion 34.

The foots splash prevention device 66 is not limited to this shape.

For example, a shape as shown in FIG. 3 is also preferable.

The footslash prevention device 72 shown in FIG. 3 has a hollow, substantially truncated hexagonal pyramid shape, each slope being recessed like a valley, and in particular, every other slope has a distinct groove shape. 74 is formed.

An opening is formed in the center of the truncated hexagonal pyramidal head.

Next, the operation of the Fouts incinerator 10 will be explained.

First, the primary burner device 42 is ignited with no foots being supplied onto the tray 30, and the flame ejected from the burner of the device causes the tray 30 and the foots disposed thereon to fly. The anti-splash device 66 becomes red hot.

The tray 30 may be made of any material as long as it is fire-resistant, but metal is preferred for ease of separation when removing the embers of the foots burned on the tray. .

When the saucer 30 and the foot splash prevention device 66 are heated to red hot and the temperature inside the first combustion chamber 20 is raised, the foot supply pump 54 is activated, and then the foot supply regulating valve 60 is activated. Open for a time, a fixed amount of foots is fed through the feed tube 56 from its feed outlet end 58 towards the foots splash prevention device 66 of the tray 30.

The foots discharged from the supply outlet end 58 and falling onto the head of the truncated cone of the foot splash prevention device 66 fall through the opening lower 0 onto the upper dish portion 34 and the surrounding area of the head. The foots that have fallen from the truncated conical slope and the foots that have fallen onto the slope of the truncated cone fall along the slope and reach the dish portion 3.
Reach the top of 4.

As a result, the foots discharged from the supply outlet end 58 are
The foots are not concentrated in one place on the dish portion 34, but are divided into small portions and dispersed directly below the opening lower 0 of the foots splash prevention device 66 and around the foots splash prevention device 66, and also fall on the slope. While falling, it becomes hot enough to easily ignite or burn.

A certain amount of foots 50 supplied to the upper pan portion 34 of the receiver pan 30 is heated to approximately 750-800 degrees by the continuously injected flame of the primary burner device 42.

In this manner, a certain amount of foots 50 is generally and uniformly raised to its temperature, reaching 750 to 800 degrees Celsius, before being ignited.

In other words, the amount of foots that can be ignited by heating to about 750 to 800 degrees is supplied.

In this way, when a certain amount of the foots 50 ignites and starts combustion, the combustion temperature rapidly rises to the complete combustion temperature.

The primary burner device 42 has a temperature in the first combustion chamber 20 of approximately 80°C, as preset in the control device.
When the temperature reaches 0 degrees or higher, the flame injection from the burner is automatically stopped.

During combustion of the quantity of foods 50, the foods expand and become liquid, overflowing the peripheral edge of the upper tray portion 34 and falling onto the middle tray portion 36.

Meanwhile, the foots also fall through the opening 40 of the upper tray portion 34 onto the middle tray portion 36, and similarly, the foots fall onto the middle tray portion 36.
It also falls onto the lower pan 38, where it is completely burned.

However, even during this time, the receiver continuously or intermittently supplies an amount of foods onto the tray 30 in accordance with the temperature inside the first combustion chamber 20, which rises due to combustion of the certain amount of foods 50.

In this way, the foods being burned fall through the openings 40 in the upper and middle pans 34, 36 onto the lower pan 38, thereby inhibiting the complete combustion of the foods in the upper pan. 34 and middle pan portion 36 are prevented from accumulating foots embers.

To explain this state in more detail, the miso-like foods (supplied foods) are fed to the foots flying prevention device 6.
This prevents the hoop (combustion hoop) from falling onto the pan 34 and becoming liquid on the pan 34 during combustion (combustion hoop) from scattering.

That is, the combustion hoop is connected to the foot splash prevention device 66.
Even if the hoop flies off due to a collision with the supply hoop that has fallen onto the pan portion 34 through the open lower 0 of the hoop, if the hoop is so large that it attempts to scatter beyond the area of the pan portion 34, the foot splash prevention device 66 Collision with the inner wall and violent scattering is prevented.

On the other hand, the feed hoop falling on the slope of the anti-foot splash device 66 reaches the dish portion 34 avoiding a violent collision with the combustion hoop, thereby preventing the combustion hoop from flying off.

Also, a foots splash prevention device 6 located on the dish portion 34 is provided.
The flame of the combustion hoop in the area surrounded by the slope 6 is guided in the vertical direction through the opening lower 0 provided at the head of the foots splash prevention device 66.

This increases the momentum of the flame and prevents incomplete combustion of the combustion hoop below the anti-splash device 66 in the area surrounded by the anti-splash device and above the pan portion 34. As well as the combustion hoop around this location, it burns and the footslip prevention device 66 is heated to a high temperature.

A predetermined amount of additional feed hoops thus added to the pan portion 34 is exposed to the hot flame of the hoops already burning in the upper, middle, and lower pan portions and is immediately ignited;
This further increases the temperature within the first combustion chamber 20.

The receiver measures the temperature in the first combustion chamber 20 so that the amount of hoop fed continuously or intermittently onto the pan 30 does not thereby increase the temperature beyond the withstand temperature limit of the refractory housing. while being controlled by hoop supply adjustment valve 60.

By the way, the certain amount of hoop 50 initially supplied onto the upper pan portion 34 is still in a state of incomplete combustion immediately after being ignited.

Therefore, immediately after the certain amount of the hoop is ignited, the secondary burner device 46 in the second combustion chamber 22 is activated, and thereby the incomplete combustion gas generated due to incomplete combustion of the hoop is transferred to the second combustion chamber 22. The combustion gas is completely combusted by the burner device in the combustion chamber, and odorless combustion gas is discharged from the chimney 64 without soot or smoke.

When the combustion temperature in the first combustion chamber 20 reaches such a state that it always maintains a complete combustion temperature for the amount of feed hoop, the operation of the secondary burner device 46 in the second combustion chamber 22 is activated as described above. It is automatically stopped by the control device based on the temperature inside the combustion chamber 22.

However, the combustion flame of the hoop in the first combustion chamber 20 reaches into the second combustion chamber 22 through a large number of holes in the refractory brick group 18, so that the red-hot refractory brick group 18 is slightly This contributes to complete combustion of the incompletely combusted gases generated as they pass through the numerous holes in the brick group.

In addition, in the hoop incinerator of the present invention, the receiving plate 30 has three
It can be made into multiple stages of more than one stage.

According to the present invention, the hoop receiver is provided on the dish with a head, a slope connected to the head and inclined outward, an open bottom, an opening provided in the head, and a slope connected to the slope in the vicinity of the bottom. A hoop anti-splatter device is disposed, the hoop being cut from a hollow truncated cone having an opening provided therein;
Since the hoop is supplied to the hoop splash prevention device in such a manner that it falls, the hoop for incineration can be dropped on the slope of the hoop splash prevention device and reach the tray. As a result, the hoop that is in a liquid state and is being burned is placed in the receiver, and the receiver guides the burning hoop onto the dish without scattering it outside the container. be able to.

If the hoop during combustion scatters and the receiver adheres to something other than the plate, the hoop attached will cause incomplete combustion, but according to the present invention, such incomplete combustion can be reliably prevented.

Further, according to the present invention, since the opening is provided in the head of the foots splash prevention device, the receiver prevents the hoops burning at a portion surrounded by the slope of the foots splash prevention device of the dish. Incomplete combustion can be prevented by guiding the flame vertically upward and increasing its intensity.

Therefore, the hoop at the above location can be completely combusted in the same way as the hoop at other locations.

Further, according to the present invention, since the hoop receiver is provided with a large number of openings at the bottom of the upper tray portion excluding the lowermost tray portion, the hoop during combustion is heated through the openings. It goes through the steps and falls to the bottom plate part.

Therefore, it is possible to prevent the embers of the hoop from accumulating on the upper pan portion, thereby avoiding a decrease in the combustion efficiency of the hoop due to the accumulation of the embers, thereby achieving a good combustion state. .
