Problems solved by technology
But for the tuyere with divergent louvers, it is impossible to accurately measure the air volume of the tuyere
Some nuclear power plants use air ducts to drill holes, and then use anemometers to measure. Although the measurement requirements can be met, it will cause irreversible damage to the equipment, and there is a risk of incomplete sealing

Embodiment Construction
[0020] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as figure 1 As shown, the embodiment of the present disclosure relates to an auxiliary air volume hood 100 for a high temperature reactor ventilation system. The inlet 120 and the air duct 140 of the outlet 130. The inlet 120 is used for sealing communication with a divergent tuyere (not shown in the figure) of the high temperature stack ventilation system, so as to introduce divergent air from the divergent tuyere into the air duct 140 . The air duct 140 can change the streamline of the divergent wind, so that the streamline of the divergent wind tends to be stable.
[0022] Specifically, when measuring the air volume of the high-temperature stack ventilation system, the inlet 120 on the air cover housing ...

The invention provides a high-temperature reactor ventilation system auxiliary air volume cover and an air volume measuring device. The auxiliary air volume cover comprises a fan cover shell, and the fan cover shell is provided with an inlet, an outlet and an air duct communicating with the inlet and the outlet. The inlet is used for being communicated with a divergent air opening of a high-temperature reactor ventilation system in a sealed mode so that divergent air of the divergent air opening can be led into the air channel. The air duct can change the streamline of the divergent air, so that the streamline of the divergent air tends to be stable. The auxiliary air volume cover disclosed by the invention solves the air volume measurement problem of a high-temperature reactor divergent air port, is simple and easy to implement, improves the measurement accuracy, and avoids irreversible damage to equipment caused by air pipe punching. The air quantity measurement deviation of the air ports can be greatly reduced, and the air quantity measurement efficiency and precision of the high-temperature reactor ventilation system are greatly improved.
Description
technical field [0001] The disclosure belongs to the technical field of air volume measurement of a ventilation system, and in particular relates to an auxiliary air volume cover and an air volume measurement device of a high temperature reactor ventilation system. Background technique [0002] At present, the air volume measurement of nuclear power plants in China generally uses the air volume hood method or anemometer method for measurement. [0003] However, the anemometer method is not only expensive, the probe is not sensitive enough to the airflow direction, and the hot wire is fragile and easy to break, but also requires calculation to obtain the average wind speed and air volume, which increases the workload of measurement. The advantage of the air volume hood is that the air volume can be read directly, the operation is convenient, and a lot of calculation troubles are reduced. This method is also called the direct air volume measurement method. However, according ...
