Embodiment 1

[0020] Such as figure 1 Shown is a schematic flow chart of a steam condensed water efficient recovery device of the present invention.

[0021] Below by specific embodiment, in conjunction with its accompanying drawing, this scheme is elaborated:

[0022] A high-efficiency recovery device for steam condensed water, in which the steam generated by boiler 1 is sent to No. 1 heating equipment 2, No. 1 steam trap group 3, No. The condensed water produced by No. 6 thermal equipment, No. 2 thermal equipment 4, No. 2 drain valve group 5, and No. 3 thermal equipment 6 is pressurized by the pressure regulating pump 7, and drained with No. 1 thermal equipment 2 and No. 1. The condensed water produced by the valve group 3 is sent to the buffer tank 8, and then sent to the boiler 1 through the high-temperature condensed water pump 10; 8.

[0023] The No. 1 steam trap group 3 is composed of two shut-off valves, a steam trap and a bypass valve.

[0024] The No. 2 steam trap group 5 is c...

Abstract

The invention relates to a steam condensation water efficient recovering device. According to the steam condensation water efficient recovering device, double-pump pressure balance, energy gradient utilization and super cooling technologies are adopted, the pressure head loss during condensation water convergence is effectively reduced, the service life of equipment is prolonged, and the purpose that the operation efficiency of the steam condensation water recovering device is improved is achieved.

Description

technical field [0001] The invention relates to a high-efficiency recovery device for steam condensed water, which belongs to the technical field of steam condensed water energy saving. Background technique [0002] Steam is a secondary energy source in many industrial fields. The condensed water produced after steam use still has a lot of heat. If it is recycled, it will receive high energy-saving benefits. At present, the recycling rate of steam condensed water in developed countries is as high as 80%, while the recycling rate in my country is relatively low, only about 40%. Therefore, it is extremely urgent to strengthen the technical research on condensed water recycling. [0003] There are certain problems in the recovery of high-temperature condensed water, that is, the condensed water after passing through multiple sets of heat-using equipment uses throttling or jet suction to balance the pressure, which will cause pressure loss, and high-temperature condensed water p...
