Raw pulp treatment and backfill reuse system and method

Abstract

A raw pulp treatment and backfilling reuse system, comprising: a raw pulp separator, which is provided with a raw pulp inlet, a circulating slurry water outlet, and a circulating mud outlet; The collecting casing set on the well hole in the middle is connected, and the other end is connected with the raw slurry inlet of the raw slurry separator through the discharge pipe; the mud stirring storage cylinder is arranged under the raw slurry separator and connected with the circulating mud outlet; A mud backfill pump, one end of which is connected to the mud stirring storage cylinder through a slurry suction pipe, and the other end is connected to a mud backfill pipe, and the mud backfill pipe is placed in the well hole to be backfilled; one end of the circulating slurry water pump is connected to the circulating slurry The water outlet is connected, and the other end is connected with the drill pipe through the circulating slurry pipe. Drilling mud is processed and backfilled in real time on site, which reduces sludge discharge, saves materials and protects the environment.

Description

technical field [0001] The invention relates to a drilling backfilling grouting technology, in particular to backfilling grouting of ground source heat pump heat exchange wells, especially a raw slurry treatment and backfilling reuse system and method thereof. Background technique [0002] At present, in the construction of heat exchange wells similar to ground source heat pumps, it is necessary to drill deep wells first, then put in heat exchange tubes, and finally backfill and compact them. In the process of drilling and backfilling, it is generally necessary to remove the drilled mud in time, otherwise the slurry will flow around, seriously polluting the work site and the surrounding environment, or causing a large area of ​​silt to be piled up. When backfilling, it is necessary to use backfilling materials such as mortar to backfill the well to achieve effective heat exchange and ensure that the foundation is stable and does not collapse or settle. Therefore, this proces...

In the process of drilling and backfilling, it is generally necessary to remove the drilled mud in time, otherwise the slurry will flow around, seriously polluting the operation site and the surrounding environment, or causing a large area of ​​silt to pile up

When backfilling, it is necessary to use backfilling materials such as mortar to backfill the well to achieve effective heat exchange and ensure that the foundation is stable and does not collapse or settle. Therefore, this process requires a large amount of material consumption.
