Problems solved by technology

[0005] 2. At present, the temperature of the tail water (the geothermal water after utilization) after geothermal heating is about 30°C, the discharge temperature is relatively high, and it is directly discharged, which seriously wastes water and heat resources
[0007] The above-mentioned heating and bathing utilization has problems such as single form of geothermal utilization, high tail water discharge temperature, low heat utilization rate, waste of resources, high maintenance costs, and short service life of equipment.

Embodiment 1

[0030] Example 1, such as figure 1 , a comprehensive cascade utilization mode for heating and bathing of medium and low temperature geothermal resources, including a geothermal water closed circulation pipeline and a softened water closed circulation pipeline;

[0031] In the geothermal water closed circulation pipeline, the production well 1 is connected to the primary heat exchanger 6 through the desander 2, and the primary heat exchanger 6 is connected to the water separator 5, and the water separator 5 is divided into two branches. The first branch is connected with the bath water storage tank 10 through the aeration device 4, and the second branch directly enters the floor radiant heating water supply pipeline 11 and the floor radiant heating return water pipeline 12, and then passes through the secondary heat exchanger 17 and then pours into the ground heat. In the recharge well 14;

[0032] The softening closed circulation pipeline is divided into two closed pipelines....

Embodiment 2

[0039] Example 2, such as figure 1 The difference between this embodiment and Embodiment 1 is that it also includes a softened circulating water replenishment pipeline, and the softened circulating water replenishment pipeline: the softened water tank 16 communicated with the tap water supply pipeline 15 is respectively connected to the primary heat exchanger 6, The water inlet pipes of the secondary heat exchanger 17 and the condenser 19 of the heat pump unit are connected.

Abstract

The invention relates to a heating and bathing comprehensive gradient utilization mode of medium and low temperature geothermal resources. The heating and bathing comprehensive gradient utilization mode comprises a geothermal water closed circulation pipeline, a softened water closed circulation pipeline and a softened and circulating water supplementing pipeline. A technology system of the heating and bathing comprehensive gradient utilization mode has the advantages that various utilization modes are combined, gradient utilization, high efficiency and energy saving are achieved, the thermal utilization rate of the geothermal resources is increased, the service life of a radiator is prolonged, the geothermal resources are protected, and resource cyclic utilization is achieved.

Description

technical field [0001] The invention belongs to the technical field of utilization of geothermal resources, and in particular relates to a comprehensive cascade utilization mode for heating and bathing of medium and low temperature geothermal resources. Background technique [0002] At present, geothermal resources, as a green and clean energy, are widely used in power generation, heating, bathing, planting and breeding and other fields. my country's geothermal resources are mainly medium and low temperature geothermal resources, and geothermal utilization is mainly for heating and bathing. The heating method can also be Divided into two types of floor radiant heating and radiator (radiator) heating. Therefore, for residential areas that combine multiple heating methods and have bathing needs, geothermal heating-bathing needs to be analyzed and designed for the process. [0003] At present, geothermal heating and bathing have been widely used, but the utilization method is r...
