Detailed Description
Referring to fig. 1, the invention discloses a geothermal water scale preventing device, which comprises a tubular metal shell, a catalyst alloy scale preventing body arranged in the shell, and a pipeline joint arranged at the end of the shell and used for connecting a water conveying pipeline. Wherein, pipeline joint adopts welding or flange connection with the casing optionally. In the embodiment, the materials of the shell and the pipeline joint are TP110T steel grade petroleum pipe sleeve steel, and the shell and the pipeline joint have good heat corrosion resistance. The catalyst alloy scale inhibitor is made of catalyst alloy, and the scale inhibition performance of the catalyst alloy scale inhibitor can be normally exerted at high temperature and high pressure, and the key point of the catalyst alloy scale inhibition is that water molecules are effectively contacted with the catalyst alloy. The bottom of the shell is contacted with geothermal water, the top of the shell is connected with a water delivery pipeline, and the geothermal water is pumped under the action of the pump body, so that water molecules pass through the shell in a fluid form and fully contact with the catalyst alloy, and the anti-scaling function is realized.
The catalyst alloy material is prepared by high-temperature combination of 7 metal elements with different electronegativity. By strictly controlling the feeding proportion and the feeding sequence of elements and adopting a special temperature-controlled smelting process, a developed dendrite structure is obtained in the material, and a structure with regularly staggered copper-rich phases and tin-rich phases is formed. When the fluid medium flushes the surface of the catalyst material at a certain flow speed, the catalyst material can present the unique functions of stably and continuously releasing electrons to the fluid system and enabling the fluid medium to generate polarization effect, thereby neutralizing the charges of scale forming metal ions, leading anions and cations in the fluid not to be easily combined to form scale, and simultaneously leading the hardened scale to be gradually dissolved and shed, thus achieving the functions of scale prevention and scale removal.
Referring to fig. 1, a coarse-hole filter screen is arranged at the bottom end of the shell to prevent sundries from entering, and meanwhile, the coarse-hole filter screen is made of TP110T steel grade petroleum pipe sleeve steel materials which are the same as those of the shell. A plurality of water inlet holes are formed in the side wall of the bottom end of the shell, and the water inlet holes are distributed gradually densely along the direction of the shell, which is close to the bottom wall, so that more water can flow in from the bottom. In this embodiment, the distribution range of the water inlet holes is about 200mm near the bottom end of the housing and occupies about 1/4 of the overall length of the housing.
Referring to fig. 2, the catalyst alloy scale inhibitor includes a chipset composed of a plurality of single chips, the single chips are of polygonal or polygonal plate-shaped structure and uniformly distributed in the shell along the length direction of the shell, and the single chips are parallel to each other and deflect with an acute angle between adjacent single chips by taking the central axis of the shell as an axis. In this embodiment, in order to make the area of catalyst alloy big enough, make the maximum diameter of single chip the same with the internal diameter of casing, in order to ensure simultaneously that rivers can normally pass through, through deflecting certain contained angle adjacent single chip for form certain gap between the single chip, the water supply stream passes through smoothly, thereby has reached better water treatment effect.
As a preferred solution, as shown in fig. 2, the single chips may be regular hexagons and the adjacent single chips are deflected by 30 ° about the central axis of the housing.
The middle part of the single chip is provided with perforations, so that water flow can flow into the space between the single chips through the perforations, and therefore contact areas as much as possible are provided, and the scale prevention effect is ensured.
Screw rods are connected between the adjacent single chips, and two ends of each screw rod penetrate through the corresponding single chip respectively and are provided with locking nuts for fixing the single chips in a screwing mode. In this embodiment, two lock nuts corresponding to a single chip may be provided, and the two lock nuts are respectively located at two sides of the single chip to clamp the single chip. The screw rods between two adjacent single chips are provided with at least three and are uniformly distributed along the circumference of the single chip, namely, the screw rods are arranged around the perforation, so that the structural stability of the catalyst alloy scale inhibitor is improved.
The water treatment capacity of the invention is generally far higher than the geothermal water pumping capacity, the main index of the antiscaling effect, namely the activation current is stabilized at about 50 microamperes, and the antiscaling effect for geothermal water is very obvious.
The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
