Description

A stirring ultraviolet sterilization device for geothermal refilling water

technical field

The utility model relates to a sterilization device, in particular to a stirring ultraviolet sterilization device for geothermal refilling water.

Background technique

After the geothermal water is produced and passed through the secondary heat exchanger, a large amount of geothermal wastewater is generated. Because geothermal wastewater contains high salinity and contains toxic and harmful chemical components, if the geothermal wastewater is discharged in large quantities, it will cause very serious environmental pollution problems. Thermal capacity is reduced. If the geothermal wastewater is recharged to the thermal storage, it can not only avoid environmental pollution, but also maintain the heat generation capacity of the thermal storage. After the geothermal water is mined from the ground, changes in temperature, pressure and other conditions cause the chemical reaction and precipitation of the geothermal water, as well as the suspended particles and microorganisms entrained by the geothermal water, which will directly cause the blockage of the geothermal wastewater recharge process. Among them, microbial reproduction will not only block the thermal reservoir, but also the iron bacteria contained in the geothermal wastewater will aggravate the corrosion of the pipeline and affect the normal recharge process.

At present, the sterilization method in the process of recharging geothermal tail water is to add sterilization agents to the water, or to use ultrafiltration membrane to filter out bacteria. However, both methods have shortcomings. On the one hand, the use of fungicides may contaminate groundwater, and on the other hand, it may cause problems such as drug resistance of bacteria; and the use of ultrafiltration methods requires large matching ultrafiltration equipment. Large investment and large area.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. For example, based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in the accompanying drawings, a stirring ultraviolet sterilization device for geothermal refilling water of the present invention includes a casing 1 with an open top, and a top cover 11 is fixed at the opening of the casing 1. There is a water inlet 2 in the center of the top cover 11, the top wall of a cylindrical filter screen 9 is fixed on the bottom wall of the top cover 11, and the inlet of the cylindrical filter screen 9 is communicated with the water inlet 2. . The cylindrical filter 9 is used to filter large particles of impurities in the water to prevent the impurities from adhering to the ultraviolet lamp tube and reduce the ultraviolet transmittance. At the same time, the filter 9 can be taken out from the housing to clean the inside of the filter.

A motor 5 is installed in the center of the bottom of the housing 1, and the transmission shaft 6 of the motor 5 is arranged in the housing through the bottom wall of the housing 1 in the vertical direction. The drive shaft 6 is connected with a stirring blade 7.

A water outlet 3 is opened on the upper part of the right side of the casing 1 , and a liquid level gauge 4 is connected to the side wall of the lower casing 1 located at the water outlet 3 along the vertical direction.

A ring-shaped metal plate 10 is arranged in the horizontal direction above the interior of the housing 1 , and the upper parts of the plurality of ultraviolet lamps 8 arranged in the vertical direction are inserted into the openings on the metal plate 10 .
