The working principle of the two-stage filtering double-valve type heat supply intelligent sewage and flushing device is as follows:
and (3) clear water operation: when normal hot water is clean and clean water, the hot water flows into the intelligent heat supply blowdown and flushing device through the water inlet 1, flows through the sewage detection device 2, the sewage detection device 2 returns detection data to the control panel 4, the control panel 4 opens the water inlet electric valve 15, closes the blowdown electric valve 16, the hot water flows into the front-end filter 3, is filtered through the front-end filter screen 13, flows through the water inlet electric valve 15, flows into the secondary filter 5 for filtering, flows into the circulating pump 6 after filtering, flows out through the water outlet 8, enters the geothermal pipe network 9 for circular heat supply, and flows out of the geothermal pipe network water outlet pipe 10 to the heating water return pipe 12; the above processes are circularly operated until the water quality is turbid, and the process jumps to the lower part to execute turbid water operation.
Automatic pressurization and heating: in the above-mentioned operating condition, the temperature detection device 7 detects the indoor temperature, send the measured data to the control panel 4, the constant temperature value is set as 20 degrees, when the measured temperature is lower than the constant temperature value 20 degrees, the control panel 4 opens the circulating pump 6, increase the hot water circulation of the pipe network, increase the indoor temperature; if the sewage enters the middle of pressurization, the circulating pump 6 is closed, and the operation is carried out by jumping to the lower part. The constant temperature value of 20 degrees is a reference value, and a user can modify the constant temperature value according to needs.
Automatic flushing: when a user starts the automatic flushing function of the control panel 4 and the time reaches the set flushing time, the device control panel 4 starts the circulating pump 6 to flush the geothermal pipe network to descale the geothermal pipe network; when the running time reaches, the operation is finished, and the circulating pump 6 is closed; and if the sewage enters the middle of the flushing, jumping out the current instruction, closing the circulating pump 6, and jumping to the lower part to execute the turbid water running.
Operation of turbid water: when the heat supply pipeline enters sewage, the sewage flows into the device through the water inlet 1, the sewage detection device 2 sends detection data to the control panel 4, the control panel 4 opens the sewage discharge electric valve 16, the water inlet electric valve 15 is closed, hot water enters the sewage discharge electric valve 16 through the front-end filter 3, the sewage discharge port 11 flows back to the heat supply water return pipe 12, and sewage is discharged. And circulating the processes until the clear water enters, and returning to the clear water operation instruction.
Low-temperature protection: when muddy water runs, the temperature detection device 7 detects the indoor temperature and sends detection data to the control panel 4, if the room temperature is lower than the heat preservation value by 10 degrees at the moment, the control panel 4 opens the water inlet electric valve 15, hot water flows into the water inlet electric valve 15 after being filtered by the front end filter screen 13, flows into the secondary filter 5 for filtering, and flows into the circulating pump 6 after being filtered, at the moment, because the circulating pump 6 does not work under the pollution discharge mode, hot water flows out from the water outlet 8, enters the geothermal pipe network 9 for circulating heat supply, and flows out to the heating water return pipe 12 through the geothermal pipe network water outlet pipe 10; thereby ensuring that the room temperature is not too low. When the room temperature exceeds the heat preservation value by 10 ℃, the control panel 4 closes the water inlet electric valve 15, stops filtering and supplying water, and the sewage discharge electric valve 16 is always in an open state in the state, waits until clear water enters, and returns to the above 'clear water running' instruction. The heat preservation value of 10 degrees is a reference value, and a user can modify the heat preservation value according to needs.
