A method for recovering overflow water from a jet pool

Abstract

The invention discloses an overflow recovery method for a water jet pond. The overflow recovery method is characterized in that a first water replenishing device pumps a first liquid in a first liquid storage pond to a second liquid storage pond, a first water return device pumps a second liquid in the second liquid storage pond to the first liquid storage pond, the first water replenishing device exchanges heat of the first liquid to a heat consuming device, and the second liquid in the second liquid storage pond is conveyed to the first liquid storage pond by the first water return device under the action of pressure difference. According to the application, the pressure difference between the second liquid storage pond and the first liquid storage pond is utilized for overflow recovery, and the overflow recovery method has the advantages of cost reduction, low energy consumption and excellent heat energy utilization effect.

Description

technical field

[0001] The invention relates to the field of recovery and treatment of overflow water in jet pools, in particular to a method for recovering overflow water in jet pools. Background technique

[0002] In thermal power plants, the air extraction system is an important system to maintain the vacuum of the condenser and pipelines and improve the thermal economy. The water jet air extraction system is widely used in generating units because of its simple structure and large suction gas capacity. middle.

[0003] In order to meet the requirements of the production process, the gas generator set needs to continuously replenish new water to the jet pool, and the supplementary water volume is 20-30 cubic meters per hour to ensure that the water temperature of the jet pool is ≤40°C. If the circulating water enters, the temperature of the circulating water will rise, reducing the actual effect of the circulation system, and the jet pool is under a normal atmospheric pr...
