Embodiment 1

[0029]Embodiment 1: In this embodiment, the water source heat pump system adopts a different well recharge system, and a water intake well and three recharge wells are set up. Both the water intake well and the reinjection well have a depth of 50 meters, a diameter of 600 meters, and a well spacing of 20 to 25 meters. The water intake pipe and the refilling water pipe are all made of steel pipes, and the diameter of the pipe is DN159mm. The water intake is equipped with a water pump (4) and a backup pump, and the design water intake is 85m 3 / h, the design flow rate of a single pump is 95m 3 / h.

[0030] The closing and opening of the electric valve on the pipeline is automatically controlled by a timing device, and the operation time of a single water intake well is set to 2 hours each time. The operation steps are as follows:

[0031] 1. When the system is running, water intake / refilling 1 # Well (26) is used as water intake well, other water intake / recharge 2 # Well (2...

Embodiment 2

[0036] The water-source heat pump system in this embodiment adopts a different-well recharge type water system, and is provided with one water intake well and three recharge wells. The closing and opening of the electric valve on the pipeline is automatically controlled by a quantitative device. After the system has been running for a period of time, if the water level of a certain reinjection well reaches the set height, the system will automatically adjust and replace the water supply well and the return water well. The implementation steps are as follows:

[0037] 1. When the system is running, water intake / refilling 1 # Well (26) is used as water intake well, other water intake / recharge 2 # Well (27), Water Intake / Recharge 3 # Well (28), water intake / recharge 4 # Well (29) operates as a recharge well; now the automatic control system automatically opens the water intake 1 # Pipe valve (10), automatically shuts off water intake 2 # Pipe valve (11), water intake 3 # Pi...

Abstract

The invention discloses a water taking well and recharge well quick-replaced pipeline system and an operation process. Aiming at the defects of high cost, complicated operation and weak heat supply effect in a traditional process, a brand new water taking well and recharge well quick-replaced device system is designed. The device system consists of a water source heat pump unit, a water pump and water source heat pump unit communicating pipe, a water pump, a water taking main pipe, a recharge main pipe and a water taking / recharge well pipe; and the water taking / recharge well pipe is connectedwith a water taking / recharge well. Under the condition of not increasing the water pump number and the pipeline number, turnoff of a pipeline bypass and a valve is used for realization.

Description

technical field [0001] The invention relates to the technical field of water source heat pumps in heating systems of construction engineering, in particular to a pipeline system and an operating process for rapid replacement of water intake wells and recharge wells. Background technique [0002] The clogging of groundwater recharge of water source heat pump is a common problem in its development. Two methods are usually used for treatment, one is to increase the number of reinjection wells, and the other is to pressurize the reinjection wells. According to the layout of the recharge well, it can be divided into the same well recharge type ground water source heat pump and the different well recharge type ground water source heat pump. The same well recharge type is suitable for use in places with limited space, and the different well recharge type groundwater source heat pump has a water intake well and a recharge well at a certain distance. This type of recharge is the mos...
