technical field

The invention relates to the technical field of industrial remote deflagration ignition, in particular to a novel remote deflagration ignition device and a method thereof.

Background technique

In the production of metallurgical industry, there are many scenes of using flames, such as ladle baking, cutting equipment, cleaning machines, etc. The common feature of fire in these places is intermittent use, usually using a long-open flame, which wastes a lot of energy.

Chinese patent ZL03128380.2 gas remote ignition method and its device, the ignition device is set at a distance of more than one meter from the burner outlet, and the ignition operation is controlled by a computer controller; , send the fire to the remote burner outlet to ignite the mixed gas. The ignition device is a sealed long cylindrical cavity, the front end of which is connected to the gas pipe. The gas inlet, ignition air pipe and high-pressure ignition head are arranged in the cavity along the advancing direction of the fire. Ignite the mixed gas to avoid the high temperature burning damage of the ignition device and the unsafe hidden danger caused by it. The design and structure of the gas remote ignition device is simple and the service life is long; because it is far away from the burner, the replacement is convenient, and the replacement does not affect the overall work of the burner.

The existing technology fails to solve the problem of intermittent fire, and it needs to be turned off when not in use, and a long-open fire or artificial on-site lighting is required when re-igniting. However, in some places at long distances or high altitudes, artificial ignition is more difficult. Therefore, it is necessary to provide a new remote deflagration ignition technology to solve the problem of intermittent use of flame in the metallurgical industry.

Further, the gas restricting chamber and the air restricting chamber restrict the flow, the restricting chamber is connected with the air/gas mixing chamber, and the spark plug is installed in the deflagration chamber to ignite the mixture of gas and air.

Further, a flameproof sheet is set between the mixing chamber and the deflagration chamber to separate the deflagration flame from the mixing chamber. At the same time, the flameproof sheet has a ventilation function to transport the mixed gas into the detonation chamber, so that the flame will not be in the deflagration chamber. The combustion of the mixing chamber effectively protects the equipment above the mixing chamber and prolongs the service life of the equipment.

Further, the aperture sizes of the gas restricting cavity and the air restricting cavity are designed and processed according to the flow rate of the detonation of the gas and the air.

Further, one side of the gas check valve is connected to the gas pipeline, the other side is connected to the gas restrictor chamber, one side of the air one-way valve is connected to the air pipeline, and the other side is connected to the air restrictor chamber. The valve is used to block the pressure generated by the deflagration in the device and will not be transmitted to the gas source pipeline, thereby protecting other instruments and equipment including the gas source pipeline.

Described a kind of novel long-distance deflagration ignition method, comprises the following steps:

S1 command is issued: ignition command is issued;

S2 gas mixing: pipeline air flows through the air restrictor cavity, and pipeline gas flows into the mixing cavity through the gas restrictor cavity for mixing and storage;

S3 ignition and deflagration: the mixture enters the deflagration chamber through the flameproof sheet, and after a certain time delay, the spark plug is energized and ignited, and the mixture in the deflagration chamber explodes and burns;

S4 flame export: deflagration produces a certain gas pressure, and the flame is exported through the inner flame guide barrel;

S5 burner ignition: a flame is generated outside the nozzle of the inner flame gun barrel, and the burner that needs to be ignited is ignited;

S6 cycle ignition: After the ignition is completed, the gas valve is completely closed, the spark plug stops igniting, and the device stops working until the next cycle ignition.

Further, the air and gas are connected to the air/gas mixing chamber through their respective flow restricting chambers, the lower part of the mixing chamber is a flameproof plate, and the lower part is a deflagration chamber, and the inner flame gun barrel transmits the flame to the outside of the gun barrel, thereby The flame is generated outside the barrel, and the spark plug is installed in the deflagration chamber and is responsible for igniting the mixture.

Further, after the detonation chamber is ignited, high-pressure gas is generated. Due to the protection of the gas check valve and the air check valve, the high-pressure gas will not be returned to the gas source pipeline, and the blockage in the inner flame guide barrel will be removed in the reverse direction.

Further, when the detonation chamber is explosively burned, the explosion-proof sheet prevents the explosion and combustion in the mixing chamber to form high-pressure gas, which damages the equipment.

Compared with the prior art, the beneficial effects of the present invention are:

One side of the gas check valve 8 is connected with the gas pipeline, and the other side is connected with the gas restricting chamber 6 .

Example 2

Referring to FIG. 2, a novel remote detonation ignition method of the present invention, when the ignition command is issued, the pipeline air flows into the mixing chamber 5 through the one-way valve 9 and the air restricting cavity 7, while the pipeline gas passes through the one-way valve 8, the gas The restricting chamber 6 flows into the mixing chamber 5, and the mixed gas enters the deflagration chamber 3 through the explosion-proof sheet 4. After a certain delay, the spark plug 2 is electrically ignited, and the mixture in the detonation chamber 3 explodes and burns, producing a certain amount of gas. Pressure, the flame is sent out through the inner flame guiding barrel 1, and the gas in the inner flame guiding barrel 1 will also be exported and burned, so that a flame is generated outside the inner flame guiding barrel mouth, and the burner that needs to be ignited is ignited. After the ignition is completed, the gas is completely turned off, the spark plug 2 stops firing, and the device stops working.

Specifically include the following steps:

S1 command is issued: ignition command is issued;

S2 gas mixing: pipeline air flows through the air restrictor cavity, and pipeline gas flows into the mixing cavity through the gas restrictor cavity for mixing and storage;

S3 ignition and deflagration: the mixture enters the deflagration chamber through the flameproof sheet, and after a certain time delay, the spark plug is energized and ignited, and the mixture in the deflagration chamber explodes and burns;

After a certain time delay, the spark plug 2 is electrically ignited, and the mixture in the deflagration chamber 3 explodes and burns. An explosion-proof sheet 4 is arranged between them, so that explosion and combustion in the mixing chamber 5 will not occur to form high-pressure gas and damage the equipment. The deflagration generates a certain gas pressure, and the flame is sent out through the inner flame guiding barrel 1. At the same time, the gas in the inner flame guiding barrel 1 will also be exported and burned, so that a flame is generated outside the inner flame guiding barrel mouth, which will need to be ignited. Burner lit. In extreme cases, when the deflagration chamber 3 generates high gas pressure and the inner flame guide barrel 1 is blocked, due to the protection of the one-way valve, the high-pressure gas will not be returned to the gas source pipe, and the high-pressure gas generated by the detonation chamber will be removed. The blocking effect of the flame barrel. The inner flame guide barrel 1 isolates the external high temperature environment from the ignition equipment at a long distance, so that the ignition equipment is far away from the working flame, so that the ignition equipment is operated in the low temperature area, and there is no equipment in the flame area, which greatly prolongs the working life of the device. After the final ignition is completed, the gas is completely turned off, the spark plug 2 stops igniting, and the device stops working until the next cycle of ignition.
