In-situ uranium extraction is a continuous process that targets production and treatment of uranium-containing leachate. In the in-situ leaching process, two main production links are well sites and hydrometallurgy plants. Wherein the hydrometallurgical plant is used for treating uranium-bearing leachate.
In the technological process of treating uranium-bearing leaching solution in a hydrometallurgy plant, facilities such as pipeline laying, house shielding and the like inevitably have gaps. Radon is used as a radioactive gas with longer diffusion length, has strong propagation capability in air and strong adhesiveness, and has certain harm to human health and environment. Therefore, in order to meet the sustainable development requirement of uranium mining industry in China, the design of radon protection in the hydrometallurgy process is very necessary to be optimized.
The liquid collecting tank is a place for temporarily storing uranium-containing leaching liquid leached by a well site, is designed to be semi-submerged, and is covered by a common color steel plate at the top. The coverage of the mode is poor in self-sealing performance, and meanwhile, gaps left by a window, an access passage and a pipeline penetrating through the wall of the side wall lead to release of radon from the liquid collecting tank to the environment.
The sealing radon-proof material is prepared by smearing or spraying a plurality of polymer film materials with low radon diffusion coefficient on the wall surface, and the radon-proof material cuts off radon escape channels and has good air tightness, so that the radon exhalation rate is reduced. However, due to the fact that various sealing radon-proof materials are high in viscosity and poor in fluidity, sealing of large gaps of the liquid collecting tank is not facilitated. It is desirable to provide a new method of sealing the in-situ leaching uranium mining sump.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention aims to provide a sealing structure and a sealing method for radon leakage of an in-situ leaching uranium collection liquid pool, which are used for solving the problems in the prior art, and the radon leakage of the liquid collection pool is achieved by adopting a plurality of sealing materials with different properties for multilayer coating.
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
As shown in fig. 1-2, the invention provides a sealing structure for radon leakage of an in-situ leaching uranium collecting pool, which takes foamed polyurethane as main aggregate for filling gaps of the collecting pool, polysulfide sealant as a radon-proof sealing main material, polypropylene paint as a two-layer radon-proof sealing material, gives consideration to the effect of beautifying the appearance, and finally realizes radon-proof sealing effect of the collecting pool.
The invention is realized by the following technical scheme: the method of the invention requires the use of the following tools and materials: the paint spraying device comprises a scraper, a graver, a paint spraying tank, an air pump, a glue gun, single-component foaming polyurethane 1, single-component polysulfide sealant 2, acrylic ester paint 3, a spray head 4 and a guide pipe. The pores are filled by the single-component foaming polyurethane 1, and a compact radon-proof layer is formed by the single-component polysulfide sealant 2 with low radon diffusion coefficient. Finally, the acrylic paint 3 with better radon-proof performance and the same environmental color is used as a second radon-proof layer and plays an attractive role.
The working principle of the invention is as follows: in order to prevent radon from damaging human bodies and the environment during uranium mining, the most important method is to prevent radon and daughter from overflowing from gaps between pipelines and houses. The invention has the function of blocking the gaps as much as possible and limiting radon in a fixed space. The single-component foaming polyurethane 1 can expand and solidify in the gaps due to the characteristics of the single-component foaming polyurethane, and can fill the gaps, but the polyurethane foam is a porous material and has poor radon shielding effect. The single-component polysulfide sealant 2 has good air tightness and small diffusion coefficient of radon, can form a compact film after solidification, has good shielding effect on radon, but the single-component polysulfide sealant 2 is difficult to form a film on the surface with larger gaps, so the single-component polysulfide sealant 2 and the single-component foaming polyurethane 1 are considered to form the composite radon-proof material. When a large gap is blocked, the single-component foaming polyurethane 1 is taken as aggregate, and the single-component foaming polyurethane 1 is filled in the gap in advance, so that the gap is fully foamed and expanded and rapidly hardened. The one-component polyurethane foam fills up all gaps and adheres tightly to them. And (3) after the polyurethane surface forms a dry plane, smearing main radon sealing material polysulfide sealant on the surface by using a scraper to achieve the sealing effect. Finally, the acrylic paint 3 is sprayed on the surface of the single-component polysulfide sealant 2 by using a paint spraying tank and an air pump to achieve the functions of resealing and beautifying the appearance.
The sealing method for radon leakage of the in-situ leaching uranium collection liquid pool comprises the following steps:
firstly, cleaning the periphery of a pore, removing sundries around the pore, then opening a single-component foaming polyurethane 1 sealing cover, rotating a spray head 4 and a guide pipe onto a polyurethane bottle body 5, shaking the bottle body, shaking the polyurethane uniformly, and facilitating polyurethane spraying. The guide pipe is inserted into the hole for 5 cm to 8cm, and pressure is slowly applied to the spray head, so that the pressure to the spray head is kept after the polyurethane is sprayed, and the polyurethane is sprayed at a constant speed. The one-component foaming polyurethane 1 is filled between gaps of houses, pipelines and doors and windows, and can expand and solidify in the gaps and even protrude out of the gaps due to the characteristics of the one-component foaming polyurethane 1.
And then removing the excessive foaming polyurethane protruding out of the surface of the building by using a graver after the single-component polyurethane 1 is solidified, so that a smooth and flat plane convenient for construction is formed. Extruding the single-component polysulfide sealant 2 on the surface of flat foaming polyurethane and the building by using a glue gunThe amount of the connecting part is 1g/cm 2 . And then the scraper uniformly coats the single-component polysulfide sealant 2 on the surface of the foaming polyurethane to ensure that the surface of the colloid is uniform and smooth and has no pore, and no gap exists between the polyurethane and the building.
After the single-component polysulfide sealant 2 is solidified, the acrylic paint 3 is arranged in a paint spraying tank, and water can be added to dilute the acrylic paint appropriately according to the viscosity of the acrylic paint 3. The paint spraying tank is connected with an air pump, the pressure of the air pump is regulated to 0.3MPa, the acrylic paint 3 is uniformly sprayed on the surface of the single-component polysulfide sealant 2, and the spraying is repeated for 3 times after the single-component polysulfide sealant is dried, so that the surface is smooth and free of pores.
It should be noted that it will be apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, but may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
