Description

Technical Field

[0001] The present disclosure relates to the technical field of wastewater heat energy recovery, and in particular to a wastewater heat energy recovery device for a saccharification workshop. Background Art

[0003] The existing saccharification workshop generates a large amount of hot water that needs to be discharged through the filter tank, sedimentation tank, and CIP10, and then discharges it to the sewage treatment workshop through the sewage pipe. However, the temperature of the wastewater is too high, and the high temperature environment can easily destroy the reproduction of sludge bacteria. Direct discharge will undoubtedly increase the difficulty of sewage treatment and energy consumption costs. Utility Model Content

[0007] In the above technical solution, when the liquid in the wastewater tank contacts the high-level tuning fork level gauge, the water pump will be started, so that the hot water in the wastewater tank enters the heat exchanger, and the cold water in the cold water tank enters the heat exchanger to exchange heat with the hot water. Then the liquid in the cold water tank and the hot water tank enter the warm water tank and the sewage treatment workshop respectively. When the low-level tuning fork level gauge in the cold water tank or the wastewater tank is triggered, the water pump will stop, realizing the automation of heat energy recovery.

[0008] In one embodiment, the saccharification workshop is provided with a filter tank, a sedimentation tank and a CIP. The water inlet of the wastewater tank is connected to the filter tank, the sedimentation tank and the CIP. The wastewater tank is installed with an inlet pump, which is connected to a tuning fork device to control the entry of wastewater. In this technical solution, when the high-position tuning fork level gauge of the wastewater tank is triggered, the inlet pump will stop collecting wastewater from the filter tank, the sedimentation tank and the CIP to prevent wastewater leakage.

[0009] In one embodiment, the cold water tank is connected to the warm water tank through a heat exchanger, and the wastewater tank is connected to the sewage treatment workshop through a heat exchanger. In this technical solution, the liquid in the cold water tank enters the warm water tank after heat exchange, and the liquid in the wastewater tank enters the sewage treatment workshop after heat exchange, thereby realizing heat energy exchange and recovery, and preventing high-temperature wastewater from entering the sewage treatment workshop to destroy the reproduction of sludge bacteria.

[0010] In one embodiment, temperature sensors are installed on the wastewater tank and the warm water tank respectively. In this technical solution, the temperature sensor adopts a PT100 temperature sensor, which can check the tank temperature in real time.

[0012] The advantages or beneficial effects of the above technical solution include at least:

[0013] The present invention discloses a wastewater heat energy recovery device for a saccharification workshop. When the liquid in the wastewater tank contacts a high-level tuning fork liquid level gauge, a water pump is activated, so that the hot water in the wastewater tank enters the heat exchanger, and the cold water in the cold water tank enters the heat exchanger for heat exchange with the hot water. Then, the liquids in the cold water tank and the hot water tank enter the warm water tank and the sewage treatment workshop respectively. When the low-level tuning fork liquid level gauge in the cold water tank or the wastewater tank is triggered, the water pump is stopped, thereby realizing the automation of heat energy recovery, reducing the steam consumption in the saccharification workshop, and reducing the difficulty of sewage treatment.

[0014] At the same time, the cold water after heat exchange enters the warm water tank, recovering the heat energy in the wastewater for production and reducing energy consumption costs. BRIEF DESCRIPTION OF THE DRAWINGS
