Description

A kind of test spontaneous combustion period of coal small simulation device
Technical field
The present invention relates to the small simulation device of a kind of comprehensive coal face goaf and tunnel loose coal spontaneous combustion, realizes the experimental simulation of spontaneous combustion of coal overall process, has solved judgement and the forecasting problem of spontaneous combustion of coal condition, place and the time under physical condition.
Background technology
In the prior art, there is the analogue means of two kinds of test spontaneous combustion of coal phases, its principle is basic identical: the air supply system forming with air compressor and air supply pipe is to coal sample reaction vessel air feed, make coal and airborne oxygen generation coal oxygen recombination reaction, emit heat and then heat up gradually, finally reaching spontaneous combustion.In experimentation, the temperature of coal reaction is carried out to overall process collection, to the CH discharging in overall process 4, CO 2, the gas such as CO analyzes.Prior art key is to adopt temperature protection system to heat up and carry out temperature protection spontaneous combustion of coal; adopt temperature control equipment to follow the tracks of the temperature in coal reaction container; and accordingly temperature protection medium is heated, medium is equated with coal reaction vessel temp, thereby realize temperature protection.Current technology has two kinds of temperature protection systems: bath temperature protection system and temperature programme case temperature protection system.Bath temperature protection system water is as temperature protection medium, and the disadvantage of this medium is that medium maximum temperature (100 ℃) is too low, can not meet the required more than 300 ℃ temperature of spontaneous combustion of coal; Temperature programme case temperature protection system adopts air as temperature protection medium, and the shortcoming of this medium is can produce heat flow while being heated, causes conducting heat inhomogeneous.

Wherein, described inner furnace is nested in described outside stove, described outside stove is placed in described ray sand bath device, described Air compressing bottle is connected with described inner furnace air inlet valve and outside stove air inlet valve respectively with inner furnace draft tube by described outside stove draft tube, the described outside stove valve of giving vent to anger is connected with described chromatograph by outside furnace outlet duct, and the described inner furnace valve of giving vent to anger passes through inner furnace escape pipe and is connected with described chromatograph; Described inner furnace temperature sensor is placed in described inner furnace inside and is connected with described temperature data acquisition device by wire, described outside furnace temperature sensor is placed in described outside furnace interior by wire and described temperature controller control linkage, described chromatograph is connected with described PC data with described temperature data acquisition device, and described sand-bath temperature sensor is placed in described ray sand bath device inside by wire and described temperature controller control linkage; Described chromatograph is connected with described PC data with described temperature data acquisition device.
Further, described outside stove draft tube and inner furnace draft tube are provided with the gas meter for measuring.
The invention has the beneficial effects as follows:
1, electricity consumption sand-bath is protected the temperature of outside stove.Sand-bath temperature is regulated by automatic temp controller, and automatic temp controller can be followed the tracks of outside stove coal sample temperature, and sand-bath temperature and outside furnace temperature are consistent, and then realizes the temperature protection to outside body of heater.
2, the temperature of the double-layer nested unit protection inner furnace of coal sample reacting furnace.The double-layer nested device of so-called reacting furnace is with coal sample reacting furnace (inner furnace) less build being placed on to the reacting furnace that build is larger (outside stove) the inside.Two reacting furnaces are all put into the fresh coal sample of same size, the place of production, granularity, and make them start to pass into air simultaneously, allow them start reaction simultaneously.Like this, outside stove is identical with the coal sample reaction process in inner furnace, and the temperature of inner furnace and outside stove keeps identical in real time, and the temperature protection of inner body of heater, without temperature difference, has so just been realized in inner furnace inside and outside so.So the measure of the first temperature protection has realized the temperature protection of sand-bath to outside stove, the measure of the second temperature protection has realized the temperature protection of outside stove for inner furnace.These two kinds of temperature protection measures have just formed the temperature protection dual fail-safe to inner body of heater.Because we only measure the coal reaction in inner furnace, therefore, through these two kinds of temperature protection, the temperature protection effect of this device inner furnace is very good.Air-flow buffer layer is all arranged at top, bottom at two-layer body of heater, makes air-flow even coal body by experiment from bottom to top, and experimental gas is through the preheating of coal sample in battle field in sand-bath and outside stove, and temperature is identical with the coal temperature of inner body of heater, then sends into from bottom of furnace body.
