Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment and instruments, in particular to a quicklime activity determination device. Background Art

[0002] The activity of quicklime is an important indicator of quicklime quality and an important basis for guiding dry flue gas desulfurization. The activity of quicklime refers to the ratio of the maximum temperature rise to the time required for digestion under specified conditions. The Electric Power Industry Standard Registration No. 31152-2011 of the People's Republic of China discloses an activity measuring device for quicklime used in dry flue gas desulfurization, which includes an iron frame, an insulated container, a rubber insulated cover, a feeding port and an insulated plug, a thermometer, an agitator, and a digital display for agitator speed regulation. The activity measuring device requires the operator to visually read the thermometer data and statistically draw the temperature curve, which is more troublesome to operate.

[0003] To solve this problem, there are some related patent technologies, such as the utility model patent "Activity determination device for quicklime for dry flue gas desulfurization" with the authorization announcement number CN 205139144U, which includes a dynamic lifting mechanism, a stirrer, an insulating cover, a temperature sensor, a water inlet mechanism, and a controller; the insulating cover is fixed on the electric lifting mechanism, and the water inlet mechanism includes a constant temperature water tank, a water pump, and a water inlet pipe, and the constant temperature water tank is connected to the water inlet pipe through the water pump; the above-mentioned stirrer, temperature sensor, and water inlet pipe are fixed on the above-mentioned insulating cover; the electric lifting mechanism, stirrer, temperature sensor, and water pump are all connected to the controller. The above-mentioned measuring device realizes the electronic reading of temperature through the temperature sensor, and realizes the automatic control of water inlet through the linkage between the controller and the water pump, which improves the intelligence and convenience of the experimental operation to a certain extent. However, the above-mentioned measuring device and the activity determination device for quicklime for dry flue gas desulfurization disclosed in the Electric Power Industry Standard Record No. 31152-2011 of the People's Republic of China have the same problem, that is, the top of the container adopts an open structure. In a device for measuring the activity of quicklime for dry flue gas desulfurization disclosed in the Electric Power Industry Standard Record No. 31152-2011 of the People's Republic of China, the top of the container is sealed by a rubber insulation cover, and then the quicklime is added through the feeding port opened on the rubber insulation cover. Due to the limited opening of the feeding port, the quicklime cannot be quickly and immediately added when adding quicklime. The insulation plug can only be sealed on the feeding port after all the quicklime is added. In this process, the heat generated by the reaction of quicklime and water in the container will be discharged in part, causing heat loss and affecting the accuracy of the measurement result. Similarly, in the utility model patent with the authorization announcement number CN 205139144U, the top of the container is also a wide-mouth structure, and the rubber insulation cover is driven by an electric lifting mechanism to close the wide mouth of the top of the container. Since the wide mouth of the container connected to the outside is larger, when the quicklime material is added, the heat is relatively more dissipated through the wide mouth, and there is a large error between the data measurement result and the true value.
