Abstract
The utility model discloses a vertical refrigerating calorimeter. An upper large barrel cover is movably arranged on the top of an upper large barrel; a small barrel is arranged in a middle barrel and at the lower end of the upper large barrel cover; an oxygen bomb is arranged inside the small barrel; the small barrel is connected with a lower large barrel through a small barrel water suction pump; the lower large barrel is connected with the small barrel through a small barrel water charging pump and a small barrel water inlet pipe; a refrigerator unit is arranged at the side part of the lower large barrel, and is connected with the lower large barrel through a refrigerating water suction pump; and the small barrel is connected with the lower large barrel through a water balance pipe and a water balance self-priming pump. The vertical refrigerating calorimeter provided by the utility model can keep a water source in a constant-temperature state by adopting a vertical refrigerator and the water balance self-priming pump, so that the test temperature is not influenced by the outside temperature to avoid temperature drift and to reduce the test error to the minimum value, thereby obtaining an accurate test result, being quick and time-saving to operate, and greatly improving heat measurement accuracy.
Description
Technical field: the utility model relates to a kind of vertical refrigeration calorimeter that keeps constant calorimetric determination combustible thermal value to use with the water temperature at water source.
Background technology: in the prior art field, the instrument and equipment basic structure of measuring the combustible thermal value forms by main frame bucket, temperature-constant bucket, it is larger that the water temperature control of calorimeter is affected by ambient temperature, caused the error of test result to strengthen, thereby affect the measuring accuracy of whole instrument.In keg, water temperature raises because coal sample burning heat release in oxygen bomb makes calorimeter when work in addition, and the water of keg is again under suction in drum, makes the water temperature in experimental water source can not keep constant, therefore the accuracy of impact experiment.
The utility model content: the utility model has overcome the drawback that existing calorimeter exists, provide the vertical refrigeration of a kind of employing to make the water source water temperature keep constant, all the time make wiring board keep temperature constant state, make probe temperature not be subjected to ectocine, the vertical refrigeration calorimeter that test result is more accurately used.The technical scheme that the utility model adopts for achieving the above object is: on it, large bung 14 is movably placed in drum 11 upper tops, keg 13 is placed in bucket 12, and be arranged on large bung 14 lower ends, oxygen bomb 16 is placed in keg 13 inside, keg 13 connects with lower drum 5 by keg suction pump 22, lower drum 5 is connected connection by keg charging pump 4, keg water inlet pipe 15 with keg, refrigerator group 1 is arranged on lower drum 5 sidepieces, and connect with lower drum 5 by taking out refrigeration water pump 2, keg 13 connects by water balance pipe 23, water balance self-priming pump 9 and lower drum 5.
The beneficial effects of the utility model are: owing to adopting vertical refrigeration and water balance self-priming pump, all the time make the water source water temperature keep constant and temperature constant state, make probe temperature not be subjected to extraneous thermal effect and produce temperature drift, test error is dropped to minimum, make test result more accurate, faster and save time, more be close to actual value, thereby greatly improved the calorimetric determination precision.
