Description

Geothermal well recharging equipment

Technical Field

The utility model belongs to the technical field of geothermal tail water recharge, concretely relates to geothermal well recharge equipment.

Background

A geothermal well refers to a method and a device for generating electricity by using geothermal energy with the well depth of about 3500 meters or hot spring water with the water temperature of more than 30 ℃, and the geothermal energy is divided into three types of high temperature, medium temperature and low temperature. The temperature is higher than 150 ℃, exists in a steam form, and belongs to high-temperature geothermal energy; 90-150 ℃, exists in the form of a mixture of water and steam, and belongs to medium-temperature geothermal energy; the sandstone geothermal deep well is a geothermal well which is higher than 25 ℃ and lower than 90 ℃ and exists in the forms of warm water, hot water and the like, and belongs to low-temperature geothermal.

When sandstone geothermal heat is used, in order to avoid thermal pollution and chemical pollution caused by direct discharge of geothermal waste water, and to maintain heat storage pressure, geothermal tail water needs to be recharged. The existing geothermal tail water recharging device generally utilizes a recharging pipe to guide geothermal tail water into a recharging well so as to achieve the purpose of tail water recharging.

Geothermal water is polluted to different degrees after being extracted with heat energy, can not be directly recharged, and needs to be treated. Suspended matters with different degrees are contained in geothermal tail water and must be removed before recharging, otherwise underground water is polluted to block a recharging channel.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a geothermal well recharge equipment to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: geothermal well recharge equipment, its structural feature lies in: the device comprises a recharge pipeline and a controller, wherein a sedimentation tank, a cyclone sand remover, a filter unit, an exhaust tank, a pressure pump and a wellhead device are sequentially arranged on the recharge pipeline according to the recharge trend of geothermal water, a water inlet is arranged at the lower end of one side of the sedimentation tank, a water outlet is arranged at the upper end of the other side of the sedimentation tank, a plurality of baffles which are alternately arranged are arranged between the water inlet and the water outlet in the sedimentation tank, one end of each baffle is fixedly connected with the inner wall of the sedimentation tank, a flow channel is formed between the other end of each baffle and the inner wall of the sedimentation tank, the filter unit consists of a plurality of self-cleaning filters which are connected in parallel, and each self-cleaning filter is provided.

Preferably, the bottom of the settling tank is provided with a slag discharge door.

Preferably, the baffle is a mesh structure.

Compared with the prior art, the utility model relates to a rationally, simple structure, intelligent operation purifies geothermal water through multistage filtration, avoids equipment to block up, and extension equipment life reduces the maintenance number of times, guarantees equipment even running, has spreading value.
