The reactor comprises a reactor body, the reactor cover and the thermocouple sleeve, wherein air inlets are formed in the bottom of the reactor body, and an air outlet is formed in the reactor cover. The reactor is characterized in that the thermocouple sleeve is fixed at the center of the bottom of the reactor body, penetrates through the bottom of the reactor body and is communicated with the outside. According to the reactor for testing the reactivity and the post-reaction strength of the coke, the thermocouple sleeve is directly fixed at the bottom of the reactor and has no need of being plugged again after the coke is loaded, so that the coke cannot be damaged; and the thermocouple sleeve is fixed at the bottom of the reactor body, and the phenomenon of poor air tightness and air leakage arising from the damage to the tip of the thermocouple sleeve due to frequent dismounting cannot occur, so that the accuracy of experiments and the simplicity and convenience in operation are guaranteed.
Description
Technical field
The utility model relates to a kind of coke reactivity and the post-reaction strength test-reactor in coking experimental facilities field.
Background technology
At present domestic main big section steel works, coal chemical enterprise all detect index with reactivity and post-reaction strength as an important quality of coke.Coke reactivity is meant that coke and carbon dioxide, oxygen and water vapor etc. carry out the ability of chemical reaction.Post reaction strength of coke be meant reacted coke under mechanical force and thermal stress effect, resist cracked with wearing and tearing abilities.CNS GB/T4000-2008 has stipulated coke reactivity and post-reaction strength test method.Its method is the coke specimen that takes by weighing certain mass, places reactor, in the time of 1000 ± 5 ℃ and carbon dioxide reaction after 2 hours, characterizes coke reactivity with the percentage of coke quality loss.Reacted coke accounts for the mass percent that reacts the back coke greater than 10 millimeters grade coke after I type drum test, the expression post-reaction strength.
Reactor is main testing equipment, and general use is resistant to elevated temperatures alloy steel reactor at present.The high-temperature alloy steel DESIGN OF REACTOR directly influences accuracy of experimental results.During test, spread one deck corundum ball at reactor bottom, keep flat sieve plate above, the ready coke specimen of packing into is then noted adjusting corundum ball height the interior coke layer of reactor is in the electric furnace flat-temperature zone before the dress appearance.The thermocouple sheath that will link to each other with loam cake inserts bed of material center, with screw loam cake and reactor shell is fixed, and then reactor is put into electric furnace and begins to detect.
At present the GB regulation the high-temperature alloy steel reactor in design, have some problems, 1, behind the coke of packing into, the thermocouple sheath that links to each other with loam cake always is not easy to be inserted into the coke centre; If operate unskilled; Be easy to cause the mechanical damage of coke, crack or coke powder, changed granularity and reaction area after the coke damage; The detection data will be directly influenced, and many detection times can be taken; 2, because thermocouple sheath is installed in and covers, take off the lid back and under hot state, be given a shock, cause the damaged easily gas leakage in the top position of sleeve pipe, thereby cause impermeability bad; 3, air admission hole only has one at the reactor bottom center, and a vent port causes when airshed is little the air inlet skewness then in a side at top.
The utility model content
The purpose of the utility model is to overcome the prior art defective, and a kind of coke reactivity and post-reaction strength test-reactor are provided.
The technical scheme of the utility model is achieved in that a kind of coke reactivity and post-reaction strength test-reactor; Comprise reactor body, reactor cap, thermocouple sheath; Have air admission hole in the reactor body bottom; On reactor cap, have vent port, it is that said thermocouple sheath is fixed on the reactor body bottom and communicates with the external world.
Further, said thermocouple sheath is fixed on reactor body bottom centre, passes bottom the reactor body and with the external world to communicate.
Further, said air admission hole respectively is provided with one on reactor body bottom centre both sides, and vent port is in the reactor cap center.
The utility model thermocouple sheath directly is fixed on reactor bottom, after coke is packed into, does not need to insert thermocouple sheath again; Therefore can not damage coke; And thermocouple sheath is fixed on the reactor body bottom, can often not dismantle, and causes overlapping the bad problem of impermeability that the point damage brings; Simultaneously, thermocouple sheath position, former reactor cap center is made as vent port, respectively is provided with an air admission hole, guaranteed the homogeneity of air inlet, make the experiment sufficient reacting, guaranteed the accuracy of experiment and the simplicity of operation on reactor body bottom centre both sides.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Among the figure: 1-reactor cap, 2-vent port, 3-reactor body, 4-thermocouple sheath, 5-air admission hole.
Embodiment
Further describe below in conjunction with accompanying drawing.
As shown in Figure 1; A kind of coke reactivity and post-reaction strength test-reactor comprise reactor body 3, reactor cap 1, thermocouple sheath 4, have air admission hole 5 in reactor body 3 bottoms; On reactor cap 1, have vent port 2; Thermocouple sheath 4 is fixed on reactor body 3 bottom centre, pass reactor body 3 bottoms and communicate with the external world, and air admission hole 5 respectively is provided with one on reactor body 3 bottom centre both sides, and vent port 2 is positioned at reactor cap 1 center.
The utility model has guaranteed the integrality of reactant; Thermocouple sheath 4 after the improvement is fixed on reactor body 3 bottoms; After coke is packed into, do not need to insert thermocouple sheath 4 again the reactor before comparing; In operation, coke be can not damage, the accuracy of experiment and the simplicity of operation guaranteed.
Because thermopair is the flat-temperature zone of assaying reaction device accurately, but also will guarantee coke in the flat-temperature zone, so through detailed calculating, it is better that thermocouple sheath 4 is welded on reactor body 3 bottom centre positions, length is about 180mm.Because thermocouple sheath 4 is fixed on reactor body 3 bottoms, can often not dismantle so that overlap point damage, bad, the gas leakage of impermeability.
In order to guarantee the homogeneity of air inflow, air admission hole 5 is designed to respectively be provided with one on both sides, reactor bottom center, and vent port 2 has guaranteed the homogeneity of air inlet in reactor cap 1 center, makes sufficient reacting.
During operation, corundum ball, patch, coke are encased in the reactor body 3 in order, cover reactor cap 1.During reaction, gas distributes through corundum ball, patch after entering into reactor body 3 through air admission hole 5 again, and the vent port 2 that passes through reactor cap 1 center after fully reacting with coke again enters into exhaust gas processing device.Thermopair is inserted by reactor body 3 bottom thermopair covers 4 and fixes with clip.
