Backflushing type heat exchange system with water pressure and temperature detecting function

Abstract

The invention discloses a backflushing type heat exchange system with a water pressure and temperature detecting function. The backflushing type heat exchange system comprises a cold water inlet pipe (5), a hot water outlet pipe (6), a waste water inlet pipe (7), a waste water outlet pipe (8), a nozzle (15), an upper heat exchange trough (1) and a lower heat exchange trough (2). An upper heat exchange device (3) and a lower heat exchange device (4) are respectively arranged in the upper heat exchange trough (1) and the lower heat exchange trough (2), a detachable filter screen (17) is arranged in the lower heat exchange trough (2), a first pressure sensor (42) and a second pressure sensor (41) are arranged on two sides of the filter screen (17) and respectively connected with a controller (14), and the controller (14) comprises a comparing module (143) respectively connected with a setting module (144), the first pressure sensor (42), the second pressure sensor (41) and a temperature sensor (25). The backflushing type heat exchange system solves the technical problem that dirt is prone to accumulating in the heat exchangers and cannot be automatically cleaned.

Description

technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a recoilable heat exchange system with hydraulic pressure detection and temperature detection. Background technique [0002] With the popularity of water heaters, people are enjoying the comfort and sanitation of showers, but the waste of water resources is also becoming more and more serious. The heated water is discharged directly after the shower. Since the water in the shower contains part of the heat and recyclable water resources, directly discharging the water after the shower not only wastes a lot of water, but also wastes the heat in the hot water. . In the prior art, there is a shower water waste heat recovery device, which can effectively collect the waste heat of shower water, but because the heat exchange device in the water heater needs to exchange heat frequently, the stains in the waste water are easy to accumulate inside, if it cannot be cleane...
