Description
Technical field
The utility model is mainly concerned with coal sample checkout equipment field, refers in particular to a kind of coal sample spontaneous combustion testing apparatus that adopts the heat-insulating design.
Background technology
When the speed of coal generation heat surpassed the speed of heat radiation, the phenomenon of spontaneous combustion may appear in colliery or storage.For fear of the spontaneous combustion of coal, should reduce in the dump as far as possible coal heat generation and strengthen heat dissipation capacity as far as possible, this principle should be applied to all collieries, process, pile up in the transportation with coal.Therefore, need to carry out the spontaneous combustion test to coal sample.Generally coal sample is placed on and carries out adiabatic spontaneous combustion test in the reactor, when reactor temperature rose to T2 by T1, gas its temperature before entering reactor also should rise to T2 by T1, and its reaction time is controlled in the tolerance band.Therefore the existing a kind of air shooter of design that needs is realized above function by this device.

Embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
As shown in Figure 1, gas path device for heat-insulating spontaneous combustion testing apparatus of the present utility model, comprise gas circuit assembly 1 and preheating assembly 2, gas circuit assembly 1 comprises draft tube 11 and air induction conduit 12, draft tube 11 is connected with outside air supply part through air intake opening 13, draft tube 11 is the outside that spiral is arranged in reactor 3, and the gas outlet 14 of draft tube 11 is connected with air induction conduit 12, and air induction conduit 12 is inserted in the cup of reactor 3.Draft tube 11 can adopt the splendid copper tube of thermal conductivity, to strengthen environment temperature to the heat conduction of draft tube 11 interior gases.Preheating assembly 2 comprises preheating water pipe 21, import heat source water from preheating water inlet 22 on the preheating water pipe 21, this heat source water can derive from the heat source water container 23, have the Small Holes that distributes according to certain rules on the preheating water pipe 21, this hole forms the spray orifice towards draft tube 11, hot water in the preheating water pipe 21 is ejected on the draft tube 11 from these Small Holes, simultaneously also with the water temp. heating around the draft tube 11.
In the present embodiment, draft tube 11 is wrapped in the outside of reactor 3 in the shape of a spiral, and comparatively uniformly environment temperature can be provided.
In the present embodiment, as shown in Figure 2, the bottom of air induction conduit 12 is coniform, and the end that air induction conduit 12 inserts reactors 3 one ends is closed, offers gas port on the sidewall, has solved tracheae and should not insert coal sample and easy blockage problem.Gas port can be designed to follow certain rule, makes gas more evenly be transported to reactor 3 inner chamber each point places by these holes.
Principle of work: coal sample is positioned in the reactor 3, and reactor 3 is positioned in the water-bath assembly.The coefficient of heat conductivity of reactor 3 is extremely low, and by heating component the temperature of water in the water-bath assembly and the temperature difference of reactor 3 interior coal sample temperature are remained in the very low range, the oxygen that enters reactor 3 is preheated assembly 2 and is preheating to the temperature identical with coal sample before entering reactor 3, by these measures coal sample is in the adiabatic environment at the trial.The coal sample temperature was risen to 40 degree by room temperature before, the temperature rise that makes coal sample by gas circuit assembly 1, preheating assembly 2 was by due to the external heat, and the oxidation accumulated heat does not occur for self.Make whole experimentation realize full automation by control system.
Below only be preferred implementation of the present utility model, protection domain of the present utility model also not only is confined to above-described embodiment, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art, the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection domain of the present utility model.
