The method of disposal of toxic and radioactive waste in the workings

 

(57) Abstract:

The inventive container of waste placed onboard Autonomous drilling apparatus having an independent energy equipment and automated programmable control unit of his work. Waste disposal is conducted by sinking produce a given diameter to a depth below the impermeable horizon, where the upward flow of fluid expelled hydrogeological conditions. When the depth of the apparatus carried on the container are piling section of this passable production by drilling device by asked him schema development and release of soil. This makes the method is fully Autonomous and highly reliable, T. K., and traversed by the apparatus waterproof horizon is filled and sealed in the same apparatus. The technical result consists in the fact that the method has high efficiency and reliability in the long time dimension of hazardous waste disposal. 2 Il.

The invention relates to the technology of recycling and dumping of toxic and radioactive waste chemical and nuclear technologies in openings formed in geological structures.

Significant and obvious disadvantages of this method are high labor, machinesfree and energy costs associated with cutting of parts of design to separate from the total body parts, contaminated, toxic, or radioactive waste - this leads to dusty work site, necessitates the use of special and unique units for capture and disposal of products, separated when cutting designs. In addition, this method requires premises infected structures in special containers, which further increases the cost of the whole process.

The closest technical and technological essence is a way of dumping of toxic and radioactive waste in an excavation, including the excavation develop in the soil, starting from the surface, lowering it listed waste and disposal by filling the free cavity /2/, /same - the Report of the U.S. Department of conversions, 1993, S. 27-30, p.6, 15, 18/.

A significant disadvantage of this method is the generation is carried out separately from the process of burial (lowering and backfilling) and separately from the localization process and protection of the buried object. This leads to a significant investment of time and money on technology for the disposal of these wastes, which do not exclude loss of toxic or radioactive waste in handling, loading, transportation and storage prior to disposal. I.e., the known method does not meet modern technical culture of handling such dangerous anthropogenic wastes.

The technical result of the present invention lies in the substantial increase of reliability and safety while reducing time and money on the implementation of all processes for the handling, disposal and containment of these wastes.

This result in the invention is achieved due to the fact that the method of disposal of toxic and radioactive waste in an excavation, including the excavation develop in the soil, starting from the surface, lowering it listed wastes and disposal, provides that the container with the specified waste or toxic, or radioactive) place in the case of Autonomous drilling machine. With this apparatus are sinking output, with the deepening of production change the speed of the upward flow from the bottom - on section of production, while Sabirabad soil (rock), then the velocity of this fluid upper layer flow and reduce settling of the soil particles (rocks), blockage of the cross-section of a cross-country production, compacting the soil in the cross-section generation propped up the bottom upward flow of drilling slurry particles which condense and fill the cross-section of a cross-country production destructible on her face soil particles, localize, thus, the container with the waste at the bottom of the production and subjected to the disposal of these wastes.

The described method is illustrated by the disclosure of the device for its implementation, where Fig. 1 shows a General view of the device of Fig. 2 shows a flow chart of use of this device.

The device is an Autonomous drilling machine (design A. I. a Plug containing an elongated housing 1, in which place the container 2, wall 3 which limit is securely enclosed in the container 4 wastes (toxic, or radioactive, or combined, represent a danger to the environment). Through the impenetrable wall 5 with the container connected 6 working part of the housing in the cavity 7 which is placed the generator working agent, in particular a generator 8, raperswilen in use).

The cavity of the generator is connected through a controlled valve 9 with the cavity of the working body 10, which represents a cone-shaped head 11, the walls of which are made working Portorosa nozzle 12 and 13 develop normal and at an angle close to the normal to the working face; nozzle 14, oriented at angles to the side walls of the bottom; and the nozzle 15, oriented in a direction opposite to the working face and at an angle (up) to the body axis.

This design of the working body of the device makes it easy to go well (production) 16 (Fig. 2) in the ground (rocks), including curved sections 17 (if necessary).

The deviation of the trajectory (Fig. 2) from the vertical (or inclined-straight) is achieved by the installation of additional nozzles 18 (Fig. 1) on the housing in its wall; the operation of this nozzle creates a moment of deviation "M" of the working body to the borehole wall that forces the working body to produce curvilinear production 17.

The operation of the device, it describes the construction of the nodes is achieved by placing in the bottom of the casing programmed control device 19, which can be programmed for Autonomous ) production (wells) and to hold during drilling production 16, in which section of its trunk 21 fill destructible on the face of the ground. For complete localization of production equip her mouth 22 and cover waterproof plug 23.

The mobility of the device when moving it in the formulation is achieved by fixing on the housing, longitudinally of its axis, gasolineras stabilizers 24 (Fig. 1), through which around the body and these stabilizers gazolapova mixture extending from the bottom, Orient the working body 10 and the housing 1 for sinking or vertical development of 25 or transfer the vertical development 16 curvilinear 17 and horizontal 26 for more targeted delivery of the container 2 at a certain horizon, for example in an array of Cambrian clay, or nevadomsky the horizon, producing waste disposal.

The method of disposal of toxic and radioactive waste in the workings is as follows. The container 2 with the prisoners in his oral waste is placed in the device (as shown in Fig. 1). The device is an Autonomous drilling machine 1 with its working body 10 is placed on the mouth 22 of development and include the generator 8 working agent (in this case gas), which is under pressure2expires of working nozzles and destroys the ground in the bottom, forming a production 16. With the increase of production speed of the rising cuttings (Fig. 2) reduce to hang particles in the cross section of the barrel 21 and the driving sections develop these particles are destroyed on the face of the ground (rocks), it is enough to set using the programming device 19, the speed of the upward flow gazolapova mixture below the speed of wool soil particles in this thread (this speed is in the range 25-60 m/s). This dirt tube is sealed upward from the bottom stream of sludge and creates an absolutely reliable localization waste disposal, while on the surface, the mouth 22, perform the waterproof tube, for example, sulfate expanding (hardening) of Portland cement.

If the burial container in a certain horizon of geostructures, production 16 is transferred, as described above, in curvilinear 17 due to the work of the stabilizers 24 and nozzle 18 and transferred production in horizontal 26, which more reliably localize the container 2 and dispose of waste.

For more robust horizontal advancement of his body section perform PR is rodolniy axis when drilling the horizontal section 26 of manufacture.

Thus, the proposed method of disposal of toxic and radioactive waste in the workings, with its technological simplicity, high reliability, efficiency and meets the modern culture of handling such dangerous anthropogenic wastes.

If necessary, the applicant may submit more complete information on the technical and technological entity, and the effectiveness of this method (excluding the possibility of providing specific information and technological details of the type of know-how).
