Description

Technological complex for the processing of liquid solutions.

The utility model relates to autonomous physical and chemical equipment for housing and communal and industrial purposes and can be used in chemical, metallurgical, food, wood, oil, meat and fish processing, and other industries for physicochemical processing of liquid media with the purpose of their cleaning, disinfection, neutralization, conversion and isolation of substances from liquid solutions. Substances can be both polluting and useful / valuable; accordingly, this useful model provides both the cleaning of solutions from pollutants and the separation of substances that are useful / valuable from liquid solutions. The volumetric productivity of processing liquid solutions by this complex varies from 0.0001 cubic meters per hour to 2000 cubic meters per hour and above.

Of the currently available and currently known devices and technical solutions, there is no complete analogue or prototype of the proposed technical solution, however, there are devices that use some types of effects on liquid solutions separately, which are given later in the text.

A known installation for the production of active organic fertilizer from waste products (RU 144133 U1, C05F 3/06, publ. 08/10/2014), using the principle of electromagnetic effects on the treated solution.

The disadvantages of this device are: the absence of chemical reagents in the processes and, as a consequence, the lack of data on the results and nature of the process of processing a liquid solution using reagents, without which the processing of certain types of liquid solutions is impossible; low productivity (8 cubic meters per hour), which cannot meet the requirements of housing and communal services facilities, the volumes of which are estimated at tens to hundreds of cubic meters per hour, and not suitable for industrial applications with volumes of hundreds to thousands of cubic meters per hour hour; also the scope of this installation is a highly specialized segment of the production of organic fertilizers.

The closest analogue to the used principle of exposure to a liquid solution is the installation of activation of processes (RU 50876 U1, 1/03, 03.03.2006). The process activation unit (UAP) contains a non-magnetic metal pipe surrounded by an external electromagnetic inductor. In the pipe, ferromagnetic needles are located as a working fluid. Under the action of a rotating magnetic field, the needles rotate with great speed around their transverse axis and move in circular orbits. Based on the description, when the processed liquid or powder media are passed through the UAE working area, the chemical, physical, mechanical, and electromagnetic processes are intensified in them. In particular, the processes of oxidation, emulsification, coagulation are accelerated.

The disadvantages of this device in the case of the treatment of liquids, including dissolved metal compounds, hydrogen sulfide and organic compounds, are: the lack of preliminary aeration of the liquid necessary to convert the dissolved compounds contained in it into an insoluble form during their oxidation; too large a gap between the teeth of the core of the inductor and ferromagnetic needles, low induction in the air gap and, as a result, a decrease in the efficiency of exposure to the medium to be treated in the specified installation; the presence of a screw, which is prone to sticking of the feed medium to its blades; the specified frequency range of the stator from 50 to 1000 Hz according to experimental data does not provide the full processing of some liquid solutions; the described possibility of using several work units having a common control unit and controller, in practice showed low efficiency.

As a prototype of the proposed technological complex for the processing of liquid solutions, an experimental setup was made, with the help of which field tests were conducted at existing enterprises in various industries. Based on the data obtained as a result of lengthy tests of the prototype, it can be argued that this utility model allows to obtain the following technical result:

1. Continuous processing of various types (types) of sewage and sludge from sewage treatment plants into highly efficient soil-forming material and water that complies with the standards for fishery water bodies (for example, SanPiN 2.1.5.980-00, GN 2.1.5.1315-03).

This technical result can be achieved only with the use of the totality of the technical means of the utility model.

In addition, trial operation has shown that positive results can also be achieved by performing the following tasks:

1. Purification of industrial, agricultural and domestic wastewater from organic and inorganic compounds.

2. The neutralization of pollution of soils, soils, sand, ponds in the aftermath of environmental accidents and disasters.

3. Purification of industrial oily effluents.

4. Purification of drains from the roadbed, storm drains, car washes, gas stations, food industry enterprises, edible fats and oils.

5. Production of compound feeds of the premix series, fertilizers, extraction of active substances and oils, processing, neutralization and disinfection of any agricultural waste.

6. Complete destruction of pathogenic flora where necessary.

7. Desalination of sea water to the specified parameters.

8. Isolation from liquid solutions of metals and metal compounds.

9. Processing liquid solutions in order to obtain substances with characteristics different from those of the components of the initial liquid solution.

The technical result is achieved by the fact that, in contrast to the well-known technical solutions, in this utility model, the principle of complex (aggregate) simultaneous and high-intensity physical and chemical effects on the medium being processed is applied. The result is achieved by a combination of influences such as electromagnetic, electrolytic, chemical, cavitation and acoustic, as a result of which the conversion of soluble substances into insoluble is carried out, which are then released from the solution by sedimentation and filtration. The technical means by which these effects are achieved are described below.

A schematic diagram of a technological complex for processing liquid solutions is illustrated in FIG. one.

The technological complex for the processing of liquid solutions is a structurally connected series-parallel technological line of blocks, systems, units and assemblies structurally interconnected by pipelines with shut-off and control valves, electric power cables and signal cables. At the entrance of the complex: the pipeline for supplying the initial liquid solution, at the exit - processed, converted, purified, disinfected, neutralized liquid and insoluble substances. The liquid and insoluble substances at the outlet are in separate containers, ready for further use.

A utility model is structurally either a modular-block structure or a structure placed inside buildings and structures. Overall dimensions of the complex (W × H × D), m: from 4 × 2 × 1 or more, depending on the type of destination and the requirements. The technological complex consists of the capacity of the initial liquid solution (1), a liquid solution supply system (2), a complex physicochemical processing unit for liquid solutions (hereinafter, KOZHR block) (3), a storage and supply system for reagents (4), a hydrodynamic separation unit (6), a fine-purification unit (5), an insoluble particle decontamination unit (7), an insoluble particle dehumidification unit (8), a unified automatic control system for shut-off and control valves and control and measuring devices (hereinafter ACS) (11), capacity the searched fluid (9) and the capacity of the processed masses (10).

The fluid solution supply system may consist of one or more pumps, a particle grinding unit, shut-off and control valves, a level meter, a flow meter, a thermometer, and other instrumentation.

This system is designed to supply the initial or with crushed particles of the liquid solution from the tank 1 to the KOZHR unit, in which under the influence of an electromagnetic field of variable frequency using ferromagnetic filling elements introduced into the solution, the physicochemical processes of cleaning, decontamination and disinfection or conversion and allocation of substances from the initial liquid solution, depending on the initial requirements. The described effect is achieved due to the fact that the ferromagnetic filling elements, being under the influence of an electromagnetic field of variable frequency, move in a plane perpendicular to the pipe axis, along trajectories that are close in shape to circles, and also in transverse directions to the specified section with a rapidly changing direction movement. These movements cause the processes of grinding particles of the solution, increasing the temperature in the liquid, accelerating the course of chemical reactions, including reactions with reagents, the formation of cavitation processes, including acoustic cavitation, in the processed medium, which change the interatomic bonds and cause chemical transformations of the substances of the processed medium. Also, between the ferromagnetic elements, electrolysis processes occur, which also cause chemical transformations of the substances of the processed medium. The intensity of the processes and the result of processing liquid solutions depends on the frequency of operation of the induction core

The KOZHR block can consist of one or several structurally combined pipelines with shut-off and control valves devices that provide excitation of the electromagnetic field, which, in turn, through the ferromagnetic filling elements of simple and complex compound forms introduced into the solution, provides a complex simultaneous high-intensity physicochemical ( electromagnetic, electrolytic, chemical, cavitation and acoustic) effects on the liquid solution flowing in them, as a result of which soluble substances are converted to insoluble and neutralization occurs, and the source of the liquid decontamination solution.

In the KOZHR block, these results are achieved due to the fact that the electromagnetic field excitation device consists of an inductor core and a working pipe made of non-magnetic material filled with ferromagnetic filling elements of simple and complex forms, through which a liquid solution flows. In addition, unlike known analogues, the core has a device for smoothly adjusting the frequency in the range from 12 to 1800 Hz. The dimensions of the core and the working tube are selected in such a way as to reduce the thickness of the air gap between them to a minimum to obtain the maximum value of induction. It was experimentally established that, compared with UAP, the current strength in the inductor winding increased by 10%, the induction in the gap increased by 10% (up to 0.75 T), and the rate of precipitation of substances in solutions increased by 30%. With the same input parameters, the device power increased by 10%.

The final composition and design of the KOZHR block is determined by the requirements for the processing parameters of the initial liquid solution.

In order to ensure that the initial requirements are met, various reagents can be supplied in the liquid solution at a given dosage, this process is provided by the reagent storage and supply system, which, in turn, can consist of a homogenization tank, reagent storage tanks, pumps, shut-off and control valves, and control -measurement devices. The completeness of this system is determined by the requirements for the processing parameters of the liquid solution in the KOZHR block.

After processing in the KOZHR block, the liquid solution is fed to the hydrodynamic fraction separation unit, in which, under the influence of the Earth's gravitational field and due to the difference in the densities of the dissolved substances compared to the solution liquid, a continuous process of separation of the treated liquid solution into sludges, sediment and suspension (suspension) takes place. Structurally, the fraction separation unit is made in the form of one or several containers independent from each other, the shape of the container can be either parallelepipedal, or conical, or cylindrical, or a combination thereof. After separation, the sludge and sediment can enter the block of decontamination of insoluble particles and / or the block of drying insoluble particles or into the tank of processed masses, depending on the initial requirements for the processing parameters of the initial liquid solution, and the suspension enters the fine block.

The fine block can consist of one or more filter elements with a given degree of filtration (500, 300, 200, 100, 50, 30, 10 microns or others). The filter element may be mesh, fibrous, porous, bulk or other type, depending on the requirements of the destination. The design and composition of this unit depends on the requirements for the degree of purification of the solution. After the block of fine cleaning, the purified liquid enters the container of the purified liquid (9).

In the block of decontamination of insoluble particles, sludge and sludge go through the stages of the processes of neutralization and disinfection, and enter the block of drainage of insoluble particles. Structurally, the decontamination unit is similar to the KOZHR block.

In the block for drying insoluble particles, sludge and sediment are separated from the liquid, and then they enter the tank of the processed masses (10). Structurally, the drainage unit can be performed either by the principle of decanter centrifuges using a system of rotating profiled drums and auger extruding the dried masses through the outlet device, or by the principle of pressing machines, where water is separated from the dried masses by the action of a piston, which then flows through the base of the mesh structure . Drained masses are removed from the working area with either a screw or a pusher. The final design of the drainage unit depends on the requirements of the purpose of the complex. The separated liquid, depending on the degree of purity of the liquid, either enters the capacity of the original liquid solution, or into a fine-purification unit.

If it is necessary to isolate useful / valuable substances from liquid solutions, the capacity of the processed masses will contain the indicated useful substances.

The described processing cycle, which takes place in the technological complex for processing liquid solutions, allows us to fulfill the tasks of both cleaning, neutralizing and disinfecting solutions from pollutants, and separating substances that are useful / valuable from liquid solutions.
