Abstract
The utility model discloses a kind of igniter of ISP smelting processes low value coal gas, belong to pyrometallurgy field, with solve when low value coal gas environment temperature less than less than 500 DEG C and low value coal gas CO contents it is relatively low, it is difficult to ignite low value coal gas the problem of.Device includes producer gas house steward, producer gas branch pipe, producer gas valve, jet for gas, also include the connecting tube being connected with jet for gas, the tail end of connecting tube is provided with low value gas regulator, and the other end of low value gas regulator is connected by low value branch gas tube with the side wall of low value gas-pipe line.The utility model in operation process only can be ignited with 14% producer gas 86% waste coal gas, make low value gas-fired and reach requirement, producer gas needed for producing has been changed to low value coal gas, not only can be with the effectively save energy, improve comprehensive utilization of energy rate, it can also reduce environmental pollution, there is preferable economy and environmental benefit.
Description
Technical field
The utility model belongs to pyrometallurgy field, and in particular to a kind of igniter of ISP smelting processes low value coal gas.
Background technology
During pyrometallurgical smelting, calorific capacity is low in 2591.5~2967.8kJ/m3（Mark）, composition is CO18%~22%,
CO210%~12%, O2＜ 0.4%, H2＜ 1%, N2For 63%~65%, smelting coal gas be referred to as low-heat value gas.Make full use of low-heat
It is worth coal gas, is the main path for reducing the blast furnace energy.The low-heat value gas of output is big in closed blast furnace normal productive process
It is most to be utilized by hot-blast stove and coke heating furnace, still, exist in use when low value coal gas is less than 500 in environment temperature
Below DEG C and when low value coal gas CO compositions are relatively low, it is difficult to which the low value coal gas that ignites, makes the low value coal gas that has more than is needed, thus producing
Cause substantial amounts of low value coal gas to be utilized in journey, cause energy waste, these low value coal gas can only be emptied, caused
Environmental pollution, while the usage amount of producer gas needed for production is also increased, increase production cost, reduce enterprise profit
Space.
Utility model content
The purpose of this utility model is to provide a kind of igniter of ISP smelting processes low value coal gas, to solve to work as low value
Coal gas environment temperature less than less than 500 DEG C and low value coal gas CO contents it is relatively low, it is difficult to ignite low value coal gas the problem of.
In order to solve the above problems, the technical solution adopted in the utility model is：
A kind of igniter of ISP smelting processes low value coal gas, including be connected in the side wall of producer gas house steward
Producer gas branch pipe, producer gas branch pipe are provided with producer gas valve, and the termination of producer gas branch pipe is provided with coal gas
Nozzle, device also include the connecting tube being connected with jet for gas, and the tail end of connecting tube is provided with low value gas regulator, low value coal gas
The other end of regulating valve is connected by low value branch gas tube with the side wall of low value gas-pipe line.
In order to further realize the utility model, connecting tube is flexible pipe.
Beneficial effect of the utility model compared to prior art：The utility model is using low value gas-pipe line, regulating valve
Door, flexible pipe and jet for gas connection structure, in operation process only can be ignited with 14% producer gas 86% waste coal
Gas, make low value gas-fired and reach requirement, will produce needed for producer gas be changed to low value coal gas, not only can be with
The effectively save energy, comprehensive utilization of energy rate is improved, can also reduce environmental pollution, there is preferable economy and environmental benefit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference implication is as follows：1st, producer gas house steward；2nd, producer gas branch pipe；3rd, producer gas valve；4、
Connecting tube；5th, jet for gas；6th, low value gas regulator；7th, low value branch gas tube；8th, low value gas-pipe line.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
A kind of igniter of ISP smelting processes low value coal gas as shown in Figure 1, including it is connected to producer gas house steward 1
Side wall on producer gas branch pipe 2, producer gas branch pipe 2 is provided with producer gas valve 3, producer gas branch pipe 2
Termination be provided with jet for gas 5, device also includes the connecting tube 4 be connected with jet for gas 5, and connecting tube 4 is wired hose, is connected
The tail end of pipe 4 is provided with low value gas regulator 6, and the other end of low value gas regulator 6 passes through low value branch gas tube 7 and low value coal
The side wall connection of gas pipeline 8.
During operation, burning things which may cause a fire disaster of the oilcloth as igniting is first lighted, burning things which may cause a fire disaster is placed on to the lower section of jet for gas 5, slowly opened
Producer gas regulating valve 3, producer gas in flow 50Nm3/ more than h can ignite producer gas, continue to tune up hair
Raw producer gas valve 3, gas flow reaches 200-500Nm3/ h, will after the peripheral temperature of jet for gas 5 is reached more than 150 DEG C
Low value gas regulator 6 is opened, and now low value coal gas is mixed into jet for gas 5 with producer gas, you can ignite low value coal
Gas.
Ignite after low value coal gas, regulation producer gas regulating valve 3 and low value gas regulator 6, shown according to flowmeter
Data, when producer gas flow is the 1/8-1/2 of low value gas flow, utilize the more economical material benefit of low value coal gas；Work as generation
When producer gas flow is the 1/7-1/3 of low value coal gas, can to greatest extent using low value coal gas, reduce producer gas and make
With；When producer gas is the 1/6 of low value coal gas, combustion efficiency is optimal, most economical.
Claims (2)
