Description

[0002] Steam quality testing includes several aspects, such as: condensing steam, collecting a certain amount of steam and non-condensable gases, measuring, and obtaining the non-condensable gas content; mixing steam with cold water and heating it, recording the initial and final temperatures and mass changes, and calculating the saturated steam dryness; testing steam superheat, that is, testing the difference between the temperature of the steam after the pressure is released and the temperature inside the pipeline.

[0003] Current steam detection methods generally use cold water as a cooling source to assist steam condensation. The entire device is complex to assemble and the container is large.

[0015] A steam quality detection method, using a steam quality detector as described above, comprises the following steps: S1: In the continuous detection stage of steam samples, the controller sends signals to the No. 1 solenoid valve, the No. 2 solenoid valve, the No. 3 solenoid valve, the No. 4 solenoid valve and the No. 5 solenoid valve, so that the No. 1 solenoid valve opens the liquid inlet pipeline, the No. 2 solenoid valve closes the channel between the gas cylinder body and the external environment, the No. 3 solenoid valve closes the liquid discharge pipeline, the No. 4 solenoid valve closes the return pipeline, and the No. 5 solenoid valve closes the reverse flow pipeline. At the same time, the controller also sends signals to the control unit of the cooling fan and the dual differential pressure transmitter to start them both; S2: The first group of steam samples flows through the liquid inlet pipeline in sequence through the steam pressure sensor to be tested, the throttling device, the steam pressure sensor after expansion, the steam temperature sensor after expansion, the superheating device and the steam temperature sensor after superheating. The above monitoring components and the steam temperature sensor after superheating respectively obtain the temperature and pressure parameters of each state point, and measure the heating parameters of the superheating device, and send them to the industrial computer for statistical calculation; S3: The steam sample after superheating treatment flows into the condenser, and the fins on the condenser tube of the condenser and the cooling fan are used to dissipate heat, accelerate the condensation of the steam sample, and produce condensate and non-condensable gas. During the start-up of the cooling fan, the power is transmitted to the cleaning component and the eddy current component through the transmission component, and the cleaning component is controlled to rotate around the condenser to wipe and clean the fins on the condenser tube. The eddy current component rotates in the condenser tube to accelerate the flow of condensate and non-condensable gas. S4: Condensate and non-condensable gas flow into the liquid cylinder body and the gas cylinder body through the liquid collecting pipeline. During the process, the condensate temperature sensor detects the temperature values ​​of the condensate and the non-condensable gas and sends the data to the industrial computer. The dual differential pressure transmitter measures the pressure difference between the non-condensable gas and the condensate through the liquid outlet pipe and the liquid cylinder liquid level measuring hose and the gas cylinder liquid level measuring hose. The above parameters are sent to the industrial computer for statistical calculation to obtain the expansion superheat, dryness, non-condensable gas content and other parameters of the steam sample; S5: After the detection is completed, the controller sends a signal to the No. 2 solenoid valve and the No. 5 solenoid valve. The No. 2 solenoid valve opens the channel between the gas cylinder body and the external environment, and the No. 5 solenoid valve opens the backflow pipeline. The non-condensable gas flows out to the outside of the detector, and the condensate flows into the circulation pipe through the backflow pipeline. At this time, the second group of steam samples flows into the condenser synchronously according to the steps of S2-S3. The condensate generated by the first group of steam samples takes away the heat of the second group of steam samples during the flow of the circulation pipe and is discharged through the drain pipeline.

[0016] Beneficial effects of the present invention: 1. The condensate generated during the steam sample detection process is used to assist the cooling fan to condense multiple groups of steam samples that are subsequently tested continuously. In the case of continuous detection of multiple samples, the condensation efficiency can be improved and the workload of the cooling fan can be reduced; 2. The power output by the cooling fan, in cooperation with the transmission component, can control the movement of the cleaning component to wipe and clean the fins on the condenser to prevent dust from affecting the efficient heat dissipation of the condenser; 3. The power of the cooling fan is used to drive the cleaning component to work, so that dust can be cleaned simultaneously during the detection process, so that it can be cleaned immediately after use. There is no need to clean when the detection system is shut down, which is more energy-efficient than the system with independent control of cleaning. 4. The brush heads on the external cleaning module and the internal cleaning module are both movable structures. When the condenser fins do not need to be cleaned, the brush heads can be folded up to prevent the brush heads from affecting the air circulation in the condenser; 5. The power output by the cooling fan, in cooperation with the transmission component, can control the movement of the vortex component in the condenser, accelerate the flow of condensate and non-condensable gas, avoid the accumulation of non-condensable gas in the dead corner of the condenser tube, and facilitate the efficient discharge of condensate and non-condensable gas into the gas-liquid collection and measurement device; 6. The dual differential pressure transmitter is used to calculate the volume of condensate and non-condensable gas, and the volume of NCG measurement results is automatically calculated, with compact structure and fast response.

The dual differential pressure transmitter (14) measures the pressure difference between the non-condensable gas and the condensate through the liquid outlet pipe (1203) and the liquid cylinder liquid level measuring hose (1204) and the gas cylinder liquid level measuring hose (1205). The above parameters are sent to the industrial computer for statistical calculation to obtain the expansion superheat, dryness, non-condensable gas content and other parameters of the steam sample; S5: After the detection is completed, the controller (18) sends a signal to the second solenoid valve (13) and the fifth solenoid valve (17), and the second solenoid valve (13) opens the channel between the gas cylinder body (1202) and the external environment, and the fifth solenoid valve (17) opens the backflow pipeline (2101), and the non-condensable gas flows out to the outside of the detector, and the condensate flows into the circulation pipe (1002) through the backflow pipeline (2101). At this time, the second group of steam samples flows into the condenser (1001) synchronously according to the steps of S2-S3. The condensate generated by the first steam sample takes away the heat of the second group of steam samples during the flow in the circulation pipe (1002) and is discharged through the drain pipeline (1902).
