Description

[Detailed Description of the Invention] This invention reduces and burns old tires, waste plastic products, etc. to generate dry distilled gas, and uses this dry distilled gas as fuel for boilers, other incinerators (hereinafter simply referred to as incinerators), etc. This invention relates to improvements to combustion equipment that operate.

As shown in Figure 1, the above-mentioned device that has been commonly used in the past has a fuel inlet 10 at the top.
and a lid 11 that seals this, and an ignition port 9 below.
It is equipped with a variable air volume blower 3 below it, and the exhaust port of the dry distillation can 1, which has a roistle 2 arranged inside, and the crater 8A of the incinerator 8 are connected by a flue 5, A nozzle 6 that functions as a burner is located at the tip of the flue leading into the crater of the incinerator 8.
A' and an auxiliary burner 7 in front of the nozzle 6A'.

In order to operate an incinerator using this device, first open the lid 11 of the dry distillation can 1, pour fuel such as an old tire into the dry distillation can 1 through the fuel inlet 10, and ignite it through the ignition port 9. Then, the lid 11 was closed, and air was supplied from the variable air volume blower 3' to perform dry distillation to generate dry distilled gas, and the generated dry distilled gas was heated in advance with the auxiliary burner 7 until the dry distilled gas was ignited. The dry distilled gas is sent to the nozzle 6A, and at the same time, the dry distilled gas is ignited and burned as it passes through the nozzle 6A, and a flame is ejected from the nozzle 6A toward the crater 8A of the incinerator 8. It is designed to operate.

Then, after a while, the operation of the auxiliary burner 7 is stopped, or even if the operation of the auxiliary burner 7 is stopped, the nozzle 6A arranged in the burner part is sufficiently heated when the operation is stopped. The dry distilled gas passing through the nozzle 6A of the burner section 6 burns when passing through the nozzle 6A of the burner section 6, thereby continuously operating the incinerator.

However, the disadvantage of the conventional device is that if the temperature of the dry distilled gas flowing in the flue 5 drops during the flow, it may be difficult to ignite when it reaches the burner section 6 and is ejected from the nozzle 6A. In some cases, tar was deposited on the inner surface of the flue 5, which impeded the flow of the dry distilled gas.

The present invention was made in order to eliminate the drawbacks of the conventional technology, and its configuration will be explained with reference to the illustrated embodiment shown in FIG. From an electric resistance heating element that is provided with a terminal for connecting a circuit that receives electricity from a power source 20, on the way to the burner part 6 formed at the tip of the flue 5 that extends into the crater 8A of the incinerator 8. A cylindrical body 12 consisting of A control device 17 is adapted to adjust and operate the variable air volume blower 3 attached to the dry distillation can or the roistle 2 stretched over the dry distillation can.
is installed outside the flue, and the detector and the control device 1 are connected to each other.
7 are connected by a circuit, and the control device 17 is connected to the control device 18 of the variable air volume blower 3 and the swing control device 16 of the rostol by a circuit. Since the present invention is configured as described above,
To operate this, first, the dry distillation can 1 is operated in the conventional manner to generate dry distillation gas, which is sent through the flue 5 toward the incinerator 8.

In order to generate this dry distilled gas, a nozzle 6A placed at the tip of the flue, that is, at the crater 8A of the incinerator 8 and serving as a burner, is heated in advance. This heating is performed to raise the temperature to a temperature sufficient to ignite and burn the dry distilled gas as it passes through the nozzle.

Under this condition, when the dry distillation gas generated in the dry distillation tank 1 reaches the nozzle 6A due to the air blown from the variable air volume blower 3, the nozzle 6A is sufficiently heated. When the dry distilled gas passes through the nozzle 6A, it ignites and burns, becoming a combustion flame and being injected toward the crater 8A of the incinerator 8, allowing the incinerator to perform its function.

After this combustion injection continues for a certain amount of time, the power supply 2
Even if the electricity supply from Nozzle 0 is stopped, the nozzle 6A is sufficiently heated, so that it will not interfere with subsequent combustion injection.

Moreover, according to the present invention, since the cylinder 12 having the above-mentioned structure is disposed in the middle of the flue 5, if the cylinder 12 is energized from the power source 20 via the temperature control device 13, the cylinder 12 can be opened. Since heat is generated due to electrical resistance, the dry distilled gas flowing through the flue 5 is heated by this cylinder 1.
2, it is heated by this cylindrical body 12, and reaches the nozzle in a heated state. Therefore, the heated dry distilled gas that has reached the nozzle is
When ejected from A, it will definitely be ignited. Further, since the above-mentioned dry distillation gas is heated in the flue, tar is not decomposed from the gas components and adheres to the inner surface of the flue, thereby preventing the flow of the dry distillation gas from being obstructed.

Additionally, if the amount of gas sent from the dry distillation tank 1 or the gas concentration decreases during the combustion spout of dry distillation gas, the combustion calories will decrease, causing various problems to combustion in the incinerator. is expected.

This decrease in the flow rate of gas or the decrease in the concentration of flowing gas is due to the fact that reductive combustion within the dry distillation vessel is not performed as ideally. This is because the amount of air blown into the dry distillation can 1 from the variable air volume blower 3 is small, or the embers inside the dry distillation can accumulate on the roaster 2, and as a result, the variable air volume blower 3
This is because the air blown from the dry distillation vessel 1 is blocked by the roistle portion, and sufficient air cannot be sent into the dry distillation vessel 1, so that reductive combustion within the dry distillation vessel 1 is not completely carried out.

However, in the present invention, since the gas flow rate detector 14 and gas component detector 15 are arranged in the flue as described above, in the event that the amount of gas flowing from the dry distillation tank or the gas concentration decreases, It is now possible to detect it immediately.

When these detectors detect the above-mentioned conditions, the detected values are immediately input to the control device 17 connected to these detectors by a circuit, and the control is performed based on the input. The device 17 is activated to activate the control device 18 of the variable air volume blower 3 to increase its rotation speed and increase the amount of air blown, or
The device 16 for shaking the rostle 2 is moved to shake the rostle 2, and the embers accumulated on the rostle 2 are shaken off from the rostle 2, improving the ventilation inside the dry distillation can, and the embers are poured into the dry distillation can. It is possible to improve the combustion of the fuel in the dry distillation tank, and to adjust the flow rate and concentration of the dry distillation gas generated in the dry distillation tank to the desired flow rate and concentration.

Further, when the flow rate or concentration of gas flowing through the flue 5 reaches a desired value due to this operation, the detector detects this again, and the control device 1 detects this.
7, and the control device 17 receives the signal.
is activated to lower the rotational speed of the variable air volume blower 3 or to stop the swinging of the roistle 2.

In this way, according to the present invention, it is possible to always generate and supply dry distilled gas having the desired gas amount and gas concentration.

Regarding the cylinder 12 disposed in the flue, as shown in FIG. A metal plate with high electrical resistance may be incorporated inside the structure in the form of a crosspiece Y or a lattice Z as shown in FIGS. 4 and 5. With this configuration, when a predetermined current is passed through the cylinder 12 from the power source 20, the electricity flowing through the cylinder 12 is transferred to the cylinder body as well as the wire mesh or cylinder stretched over the cylinder nozzle. Electricity is applied to the metal plate incorporated in the main body, which generates heat due to electrical resistance, and the dry distilled gas passing through the cylinder 12 is heated more efficiently.
