Description
Technical field
The utility model relates to a kind of gas combustion bleeding device.
Background technology
In fields such as oil, chemical industry, metallurgy, light industrys, be extensive use of the burning bleeding device, be used for processing plant and produce poisonous, the pernicious gas of discharging.At the difference of plant produced technology, need the thermal value range of emission gases to change very greatly, generally speaking, calorific value is greater than 200BTU/ft
31780kcal/m
3The time, discharging gas can finely burn; Be lower than 200BTU/ft
3Waste gas, the gas that must mix high heating value improves the calorific value of waste gas, this burner claims " heat absorbing type torch " (seeing accompanying drawing 1), mixed gas is in wind-collecting cover 9 internal combustion.When discharging gas calorific value is lower than 100BTU/ft
3890 kcal/m
3The time, also available torch burning, but the exotic fuels amount that will add is a lot.Therefore, when discharging the gas calorific value less than 100BTU/ft
3, be not suitable for as torch burning.And in engineering practice, existing much needs the processing calorific value to be lower than 100BTU/ft
3Situation, such as: metallurgy industry, the calorific value of blast furnace gas is generally 85BTU/ft
3744kcal/m
3～103BTU/ft
3920kcal/m
3, and discharge capacity is very big.At present, a lot of steel mills of China, there is following problem in the blast furnace gas diffusion system:
(1) consumes a large amount of valuable exotic fuels gas and diffuse gas with low heat value and mix, guarantee
The good combustion of blast furnace dispersing gas;
(2) igniter is caught fire, and emission gases can't be burnt.
Summary of the invention
The purpose of this utility model is to provide a kind of can make that low-BTU gas fully burns, energy-conservation burning bleeding device.
For achieving the above object, the technical solution of the utility model is: comprise main combustion barrel, igniter; Comprise that also flow deflector, companion burn endless tube, gas pipeline; Said flow deflector is arranged in the main combustion barrel, diffuses gas with guiding and enters in the flame of accompanying burning endless tube and main combustion barrel composition; Said companion burns endless tube and is arranged at main combustion barrel nozzle outer ring, and this gas pipeline burns endless tube circumferential array setting and burns endless tube with the companion along the companion and is connected, and burns endless tube by the gas pipeline companion and is connected with source of the gas, realizes the companion is burnt the endless tube air feed; Said igniter is arranged at the companion and burns the endless tube outside, is fixedly connected on the support.
Further, said igniter comprises the little burner of igniting, spark plug, is used for lighting the companion and burns the higher gas of calorific value that endless tube sprays.
Said flow deflector is the oar shape in the shape of a spiral.
Also be provided with hurricane globe, bearing support again; This hurricane globe is arranged at the outside, main combustion barrel upper end by bearing support, makes mist stay for some time in the combustion chamber that hurricane globe is formed, and plays the thermal incineration and the retention flame, makes it not be subjected to the influence of external environment condition.
Also be provided with thermocouple, this thermocouple is arranged at the outside, hurricane globe upper end, and probe inserts in the hurricane globe, is used for the combustion position of flame detection.
Advantage of the present utility model is: 1, abandoned traditional additional high heat value gas, be used to improve the calorific value of discharging gas, made the calorific value of mist reach certain level, thereby make the conventional method of mist good combustion in burner torch head.2, this burner apparatus adopts and diffuses the method that gas imports the retention flame that has fired with low-calorie, accompanies a small amount of high heat value gas that burns the endless tube retention flame as long as consume to keep, and just can make a large amount of low-calorie gas that diffuses be able to abundant burning.
