Problems solved by technology

[0003] At present, the existing degassing, impurity removal and oil removal treatment methods and devices for sandstone geothermal recharge tail water are all independent equipment through system integration, so as to realize the functions of degassing, impurity removal and oil removal, but the existing technology has the following Disadvantages: usually separate degassing equipment, filter and degreasing equipment and filter degreasing equipment are used comprehensively for system integration, and the functions of degassing, impurity removal and oil removal are realized through multi-level treatment, and the system configuration and equipment investment are high. The process is complicated, the operation is complicated, and the floor space is large; the filtration and impurity removal usually adopts the combined filtration form of sand filter, scraper filter and core filter, and high-precision filtration can be achieved by gradually improving the filtration accuracy. It can realize coarse filtration, easy diafiltration, long backwash regeneration time, and large water demand; scraping filter and some core filters can realize online backwash regeneration, but the filtration flux is low in high-precision filtration, and it can handle large flow Liquid requires a large filtration area to meet the demand, and there are disadvantages that it is difficult to completely strip solids during backwashing operation, and the backwashing regeneration effect is poor; some core filter elements cannot be regenerated, and when the particles are fine and the solid content is high, use After a period of time, the filter screen or filter element will produce non-renewable clogging, and the filter element must be replaced frequently, resulting in increased costs

[0004] Geothermal resources have a wide range of uses. The difference between them and fossil fuels is that they do not need to be burned. They have the special advantages of saving fossil fuels and not causing urban air pollution. They can be used repeatedly and are renewable resources. Deep groundwater has its own circulation system. After part of the hot water is pumped up, it will be continuously replenished from afar. In this sense, geothermal resources are inexhaustible and inexhaustible. As an alternative new energy source, its development and utilization are being Attention has been paid to it; however, the following problems generally exist in geothermal water equipment used in China at present: 1. Reinjection rate: Due to the serious overexploitation of geothermal heat in various places in recent years, geological subsidence in some areas has been caused

2. Anti-corrosion problems: The problem of geothermal water corrosion on metals is common and very serious; the most common corrosion components in geothermal water are chloride ions and dissolved oxygen.

3. Heat energy loss: The transportability of geothermal water is relatively low, the limit distance for transporting high temperature geothermal water is about 100km, and the transportation distance for natural steam is only about 10km; the utilization rate of geothermal water heating depends on the temperature of geothermal water and its heating The higher the temperature of the discharged water, the higher the temperature of the geothermal water and the lower the temperature of the drainage after heating, the higher the utilization rate of its heating; in view of the problems encountered in the use of geothermal water, this design provides a mobile integrated filter Separation system, processing capacity: 150m3 / h~500m3 / h, filtration precision: 1~100μm
