Full-automatic energy-saving and pressure-stabilizing device for directly supplementing water from primary side to secondary side in heat exchange station

Abstract

The invention discloses a full-automatic energy-saving and pressure-stabilizing device for directly supplementing water from a primary side to a secondary side in a heat exchange station. The full-automatic energy-saving and pressure-stabilizing device comprises a controller, a heat exchanger, a primary side heating network water return pipe and a secondary side heating network water return pipe, wherein a water charging pipe and a water supplementing pipe are arranged between the primary side heating network water return pipe and the secondary side heating network water return pipe, and are connected with the primary side heating network water return pipe through a water entering main pipe and connected with secondary side heating network water return pipe through a water discharging main pipe; a flow detector and a flange ball valve are arranged on the water discharging main pipe; the flow detector is connected with a flow transducer; two stages of turn-off electromagnetic valves are arranged on the water supplementing pipe; an electric adjustment valve or a variable-frequency water supplementing pump is arranged between the two stages of turn-off electromagnetic valves; the primary side heating network water return pipe is equipped with a first pressure transducer; and the secondary side heating network water return pipe is equipped with a second pressure transducer. According to the full-automatic energy-saving and pressure-stabilizing device for directly supplementing water from the primary side to the secondary side in the heat exchange station, a water treatment device and a water supplementing water tank in the conventional system are canceled, so that the equipment of a constant-pressure water supplementing system is greatly simplified; and the area occupied by a heating station is reduced, and the investment is saved.

Description

technical field [0001] The technology of the present invention belongs to the field of urban hot water heating, and belongs to the technology of automatic water replenishment and constant pressure of heating network, and is specifically a fully automatic energy-saving constant pressure device used in the heat exchange station to directly replenish water from the primary side to the secondary side. Background technique [0002] In the field of urban hot water heating, indirect heat exchange stations are commonly used. Indirect heat exchange stations usually need to be equipped with a complete water supply constant pressure system. The conventional system includes: water treatment device, water supply tank, water supply pump, control Valve groups, power distribution and control cabinets and other equipment have many equipment configurations. This traditional indirect heat exchange station's automatic water replenishment and constant pressure system passes tap water through a w...

Problems solved by technology

For this traditional indirect heat exchange station, since the general tap water pressure is 0.2-0.3MPa, the tap water becomes normal pressure after passing through the water tank. On the one hand, the pressure is not fully utilized, and on the other hand, the water quality requirements of the primary side heating network are higher. , must undergo softening and deaeration treatment, and the water quality is better than that of the secondary side, but the water of the primary side heating network has not been fully utilized; and the heat exchange station occupies a large area, the project investment is large, and the power consumption of the heat exchange station is high. high water consumption
