Purpose of the present invention provides a kind of gathering-device for the gas carbon oxidation factor on-line testing of civilian coal seam for existing weak point in the above-mentioned prior art just.
The technical solution adopted in the present invention is: place a not exclusively truncated cone-shaped cover of sealing on original gas range, purpose is for each component of gas behind the gas firing of the civilian coal seam of on-line measurement, on this device, by gas analyzer and opium pipe, effectively volume fraction, temperature, flow and the pressure etc. of each component of gas behind the gas firing of the civilian coal seam of on-line measurement.
Technical scheme of the present invention realizes by following concrete technical measures:
Gathering-device for the gas carbon oxidation factor on-line testing of civilian coal seam of the present invention comprises the device body that is provided with the sandwich wall type cooling chamber that is made of interior external conical-tube; The lower port in the hollow-cone chamber of described device body is the gas access, and upper port is gas vent; Be provided with the cooling water inlet pipe mouth that is communicated with the sandwich wall type cooling chamber in the bottom of the external conical-tube barrel of device body, be provided with the cooling water outlet pipe mouth that is communicated with the sandwich wall type cooling chamber on the top of the external conical-tube barrel of device body.
The bottom of device body of the present invention is provided with form.
Beneficial effect of the present invention is as follows:
The collections such as volume fraction, temperature, flow and pressure of each component of gas after utilizing device of the present invention for the civilian coal seam of on-line measurement gas firing facilitate, on this device basic, by gas analyzer and opium pipe, effectively volume fraction, temperature, flow and the pressure etc. of each component of gas behind the gas firing of the civilian coal seam of on-line measurement are for the calculating of civilian coal seam gas carbon oxidation factor provides accurately data parameters.The present invention obtains to calculate the data parameters of the oxidation of coal factor under different operating modes, then utilize the computing formula of the oxidation of coal factor to calculate.
The present invention not only goes for the measurement of gas behind the gas firing of civilian coal seam, also can be used for similar therewith situation.

Embodiment
The present invention is described in further detail below with reference to embodiment (accompanying drawing).
As shown in Figure 1, 2, the present invention comprises the device body that is provided with sandwich wall type cooling chamber 5 that is made of interior external conical-tube for the gathering-device of civilian coal seam gas carbon oxidation factor on-line testing; The lower port in the hollow-cone chamber of described device body is gas access 1, and upper port is gas vent 2; Be provided with the cooling water inlet pipe mouth 3 that is communicated with the sandwich wall type cooling chamber in the bottom of the external conical-tube barrel of device body, be provided with the cooling water outlet pipe mouth 4 that is communicated with the sandwich wall type cooling chamber on the top of the external conical-tube barrel of device body; The bottom of described device body is provided with form 6.
Fig. 3 is another embodiment of the invention, is that with the difference of structure shown in Fig. 1,2 bottom of described device body does not arrange form.
More specifically: device of the present invention is comprised of the two large divisions, i.e. exhaust collection and tail gas cooling.The shape of exhaust collection part be as a whole a handstand like conical structure, such structure both had been conducive to the abundant burning of gas, was conducive to again the collection of tail gas and discharged without pressurization; The cooling principle of tail gas cooling segment is to carry out exchange heat with inner tail gas by the adverse current of water, reaches the effect of cooling.The cover of this spline structure provides a stably background for the test of civilian coal seam gas carbon oxidation factor, so that the parameter of surveying is more accurate.On this device, by gas analyzer and opium pipe, effectively volume fraction, temperature, flow and the pressure etc. of each component of gas behind the gas firing of the civilian coal seam of on-line measurement.
Fig. 4 has provided total process of the measuring method of civilian coal seam gas carbon oxidation factor, be that whole experimentation entrance and exit gas to civilian coal-seam gas under different operating modes carries out on-line testing, then in the formula shown in the measurement result substitution of putting in order is following, can draw the oxidation of coal factor of civilian coal-seam gas.This method is not only easy but also accurate, and for we have saved a lot of time.
The computing formula of civilian coal seam gas carbon oxidation factor is as follows:
In the computing formula:
-oxidation of coal the factor, dimensionless;
-amount of substance,
C-gas volume percentage, %;
-flow,
-the unit interval,
-pressure,
-temperature,
In sum, the invention solves the problem of the civilian coal seam of on-line testing gas carbon oxidation factor, adopted method of testing and the computing method of civilian coal seam gas carbon oxidation factor under different operating modes.The invention provides the method for the civilian coal seam of short, the online quick test of a kind of little, debug time of taking up room gas carbon oxidation factor, simultaneously also proposed how efficiently to utilize the measure of civilian coal-seam gas, reduced the rough burning of civilian coal-seam gas to the pollution of surrounding environment, so that civilian coal seam is so incensed that to effectively utilize.The most outstanding characteristics of this proving installation be can be online the civilian coal seam gas carbon oxidation factor measured calculate required parameter values, then calculate the oxidation of coal factor of civilian coal-seam gas by computing formula.The computing formula of the oxidation of coal factor derives according to conservation of matter principle, flow accuracy requirement in this computing formula parameter is very high, the present invention has considered this point, and adopt opium pipe to carry out the mensuration of flow in the exit of incomplete seal bootr, calculate exactly the oxidation of coal factor of civilian coal-seam gas, and obtained useful effect.
