Abstract
The invention discloses a coal heating value determinator which comprises a constant temperature bucket and an oxygen bomb. The constant temperature bucket comprises an inner bucket body and an outer bucket body, a stirring device and a heater for adjusting water temperature are arranged at the bottom of the inner bucket body, and a temperature measurement device is arranged on the upper portion of the upper bucket body. The inner bucket body is connected with a first water tank through a water inlet pipeline and a water outlet pipeline. A first valve is arranged on the water inlet pipeline, and a second valve is arranged on the water outlet pipeline. A cavity for containing water is formed in the wall of the outer bucket body. The coal heating value can be determined continuously, fast and accurately, and testing efficiency is improved.
Description
Technical field
The invention belongs to detection field, particularly relate to a kind of heating value of coal analyzer.
Background technology
The thermal value of coal is not only the important indicator evaluating steam coal quality, also be the necessary means of Study on Coal qualitative change law, grade of coal, in addition the thermal value measuring coal can design for Industrial Boiler, combustion apparatus type selecting and steam coal valuation etc. provide theoretical foundation, has great directive significance to the production and selling of coal.
The instrument that the mensuration of heating value of coal is conventional is heat measurement instrument.By bucket water temperature volume change in heat measurement instrument, measure the thermal value of coal.But the thermal capacity of heat measurement instrument may change along with the change of temperature, this will make heat measurement instrument initial temperature different, and the result recorded is inconsistent, affects the accuracy of heat measurement instrument measurement data.
In addition, generally, test sample is generally multiple, and therefore experiment must be carried out in continuous continual situation.But after experiment is finished, the heat that test sample substance combustion produces raises before interior inner bucket water temperature can be caused to compare experiment, and the current recovery tank in interior bucket, will inevitably cause the water temperature in water tank to raise.If bucket water inlet is tested again now, before causing twice experiment in front and back, water temperature is inconsistent, and experiment accumulation is more continuously, and the temperature difference is larger, and this has larger impact to the degree of accuracy of experiment.Therefore, after generally taking often to finish an experiment, need to wait for that certain hour carries out experiment next time after reducing by the water temperature in water tank again.So, experimenter need wait for that the long period can carry out test next time, greatly have impact on testing efficiency.
Again, the stirring apparatus of existing heat measurement instrument is contained in the side of interior bucket oxygen bomb, and the time of the needs that therefore water temperature stirred is also longer, have impact on testing efficiency.
Summary of the invention
The invention provides a kind of heating value of coal analyzer for solving the problem, can measure the thermal value of coal continuously, fast and accurately, improve testing efficiency.
For reaching above-mentioned technique effect, technical scheme of the present invention is:
A kind of heating value of coal analyzer, comprise constant temperature bucket and oxygen bomb, described constant temperature bucket comprises inner barrel and outer barrel, and described bottom of the barrel is provided with stirring apparatus and regulates the well heater of water temperature, and interior bucket top is provided with temperature measuring equipment; Interior bucket is connected with the first water tank with outlet conduit by inlet channel; Described inlet channel is provided with the first valve, described outlet conduit is provided with the second valve; The bucket wall of described outer barrel is the cavity be filled with water.
Further improvement, described outlet conduit is linked with the second water tank, is provided with the 3rd valve below the second water tank.
Further improvement, described second water tank inside is provided with heat sink.
Further improvement, described first valve, the second valve and the 3rd valve are solenoid valve.
Further improvement, described temperature measuring equipment is electropsychrometer.
The present invention is by arranging well heater within the inner barrel, and when making to measure heating value of coal, the initial water temperature in interior bucket is in a temperature higher compared with room temperature.Often survey a sample, after the water in replacing in bucket, again started well heater, by water temp. heating that higher initial temperature to setting.Faster than scattering cooling rate owing to heating up, so can determination efficiency be submitted to.Stirring apparatus is arranged on bottom of the barrel, the water in interior bucket can be made to stir faster.The setting of the second water tank, can make the water after measurement first be stored in the second water tank, in order to avoid have influence on the water temperature in the first water tank.The setting of heat sink in second water tank, when can make to measure huge amount sample, timely by the water for cooling in the second water tank, enables water recycle in time.
Accompanying drawing explanation
Fig. 1 is embodiment schematic diagram.
