Burn device.
Background technology
Gas is methane as the main pernicious gas of underground coal mine and danger source, main component.In order to rationally solve
Gas body is produced and is used by mine safety problem, has not only been solved the safety problem of coal mine but also has been improved economic benefit,
Reduce carbon discharge capacity.But the gas density for having 70% in the gas total amount that extraction goes out is less than 8%, the combustion of this part gas routine
Burning mode is difficult to be stablized burning, and gas of the usual concentration less than 6% is all directly discharged into atmospheric environment, and resource is caused
Greatly waste, while also polluted environment.
Intermittent combustion is burnt different from conventional stationarity, it is the burned of the periodically pulsing under certain acoustic condition control
Journey.The result of high sound intensity pulsation can greatly strengthen mixing, heat transfer and mass transport process, come from the angle of energy conversion efficiency
It sees, the certain form of rough burning under controlled condition, which can become, improves efficiency, saves a kind of effective way of fuel.Cause
This, occur some using combustion instability and certain acoustic condition control under specialized work under thermoacoustic pulse state
Pulsating combusting device, present pulsating combusting device is 5% to the lower limit requirement of gas density, but the concentration of gas is produced in actual production
Constantly changing, when extraction gas density is slightly below 5%, pulsating combusting device can fail, and the utility model passes through change
Tail pipe length adjusts combustion chamber ripple frequency, so as to meet the requirement that continuous service is stablized in various concentration gas intermittent combustion,
Solve the problems, such as combustion instability caused by variation ofgas density in traditional intermittent combustion mode.
The content of the invention
The purpose of the utility model is to overcome above-mentioned deficiencies, provide a kind of tail pipe adjustable pulse combustion device, by certainly
The dynamic acoustic and thermal effect for adjusting tail pipe length and carrying out synchronous intermittent combustion, it is steady in wider concentration range so as to fulfill low concentration gas
Fixed burning.
Technical solution is used by the utility model solves its technical problem：A kind of adjustable intermittent combustion dress of tail pipe
It puts, including gas inlet 1, combustion chamber 2, basic tail pipe 3, actuator 4, telescopic rod 5 and mobile tail pipe 6, it is characterized in that, tail pipe
It is divided into 6 two parts of basic tail pipe 3 and mobile tail pipe, basic tail pipe 3 is fixed on the lower section of combustion chamber 2, and mobile tail pipe 6 is connected to base
Scalable on plinth tail pipe 3, actuator 4 is mounted on basic tail pipe 3, motor or hydraulic-driven can be used, telescopic rod 5 is with performing
Device 4 is connected with mobile tail pipe 6, and gas inlet 1 is connected with combustion chamber 2.
The beneficial effects of the utility model：While tail pipe length is changed, entire pulse combustion device is not significantly changed
Overall structure, have the advantage that simultaneously.
1. the arrangement achieves flexible, the fuel factor in synchronousing combustion room of automation control tail pipe, strengthen burning is indoor
Acoustic and thermal effect efficiently solves the problems, such as that the intermittent combustion under the conditions of variation ofgas density is continual and steady.
2. the device realizes quick response combustion chamber internal heat effect, energy consumption is smaller.
3. the device changed on original pulsating combusting device architecture basics it is smaller, it is easy to spread to needing to widen intermittent combustion
The occasion of the use scope of device.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Description of the drawings
Fig. 1 is a kind of adjustable pulse combustion device structure diagram of tail pipe of the utility model.
In figure：1- gas inlets, 2- combustion chambers, 3- bases tail pipe, 4- actuators, 5- telescopic rods, 6- movement tail pipes.
Specific embodiment
Referring to Fig. 1, the utility model proposes a kind of adjustable pulse combustion device of tail pipe, including gas inlet 1, combustion
Room 2, basic tail pipe 3, actuator 4, telescopic rod 5 and mobile tail pipe 6 are burnt, it is characterized in that, tail pipe is divided into basic tail pipe 3 and mobile tail
6 two parts of pipe, basic tail pipe 3 are fixed on the lower section of combustion chamber 2, and mobile tail pipe 6 is connected on basic tail pipe 3, scalable, is performed
Device 4 is mounted on basic tail pipe 3, and motor or hydraulic-driven can be used, and telescopic rod 5 is connected with actuator 4 and mobile tail pipe 6,
Gas inlet 1 is connected with combustion chamber 2.It is exported by actuator 4 and telescopic rod 5 is promoted to shorten or extend so as to fulfill entire tail pipe
The change of length.The utility model is by changing tail pipe length come change burning room ripple frequency, so as to meet various concentration watt
The requirement of this body steady pulsation burning solves combustion instability caused by the variation of gas bulk concentration in traditional intermittent combustion mode and asks
Topic.
Using the adjustable pulse combustion device of the tail pipe of the utility model, realize that segmentation is passed through 6% and 4% concentration gas
Stablize burning example.
Using 20min as time step, alternating is passed through 6% and 4% concentration gas, and telescopic rod 5 is controlled by setting actuator 4
Control program, while detect the indoor temperature variation curve of burning, obtain following graph：
Pass through the curve, it is known that in 2h, though temperature mechanical periodicity amplitude of variation is little in combustion chamber 2, illustrate to burn
Without de- fiery phenomenon in room 2, it is known that 2 combustion process of combustion chamber is relatively stable, realizes the gas body pulsation of 6% and 4% concentration
Burning, the device can stable operation, very considerable gas utilization rate can be reached, reduce the discharge of low concentration gas, reduce
Environmental pollution.
