Description

 The invention relates to devices containing self-cleaning filters for filtering or filtering with degassing liquids, with the separation of emulsions such as water in oil, as well as for cleaning liquid mixtures with the distillation of certain components, for cleaning gaseous and gas-liquid media. The primary field of application is the filtration of oils and fuels for engines, as well as partial or complete regeneration of used cutting fluids.

 A known installation for gas purification (SU 356833, class B 01 D 35/12, 1968), in which to reduce the pressure pulsations of the filtrate when turning on self-cleaning filters in the regeneration mode, a part of the filtrate is discharged from the pressure section of the system. The disadvantage of this installation is that the medium used to stabilize the filtrate pressure is not used for self-cleaning the filter.

 Also known installation for filtering liquid (FR 2502970, CL B 01 D 25/08, 1981 or patent SU 1232126 A3, CL B 01 D 27/00, 1982 -analog), containing a self-cleaning filter with washing the filter surface with countercurrent filtrate, in which, in order to damp the pulsations of the counterflow itself and to stabilize its flow rate, a shock absorber is built into the channel for removing contaminants, made in the form of an alternating throttle that is in communication with the air cavity under pressure. The disadvantage of this installation is the lack of feedback in the flow rate regulator on the pressure of the filtered medium in the filtration system or on the flow of the filtrate, which can destabilize the supply of the consumer filtrate and can lead to pressure overloads of the system. Practical application of the installation requires the use of an autonomous regulator of the filtrate parameters, the operation of which will require an additional amount of liquid.

 In addition, there is known a method of washing the filter with reverse current of the filtrate, and a filter operating in this way (DE OS 3934947, CL B 01 D 29/62). In this filter, a filtrate flow rate stabilization device is integrated to suppress disturbances caused by the operation of the self-cleaning mechanism by synchronously replenishing the amount of liquid spent on washing the filter surface. The disadvantage of the filter is the narrow specialization of the regulator, which excludes the possibility of damping disturbances in the control system from the consumer or from the discharge pump. This disadvantage necessitates the use of an additional device for controlling the parameters of the filtrate for these purposes and the expenditure of an additional amount of liquid without first using it to self-clean the filter.

 Closest to the present invention is a vibrocomplex (SU 1736047 A3, class B 04 C 9/00), which provides for controlling the flow of filtrate through an adjustable throttle connected to the filter drive cavity by changing the amount of liquid discharged from this cavity. The disadvantage of this vibrocomplex is that the liquid spent on regulating the flow rate of the filtrate in the system is used only to drive the filter, and an additional amount of the filtered medium is used to remove the washed away contaminants.

 The fluid flow rate for the removal of contaminants is the main share of its losses from the pressure sections of the filtration system, inevitable when using self-cleaning filters. At the same time, when controlling the parameters of the filtrate, for example, the flow rate of the filtrate or pressure, the expenses of the liquid discharged into the pressureless zone of the system are also inevitable. In order to intensify the self-cleaning of the filter, it would be advisable to solve both of these problems, spending mainly the same amount of pumped agent. It begs to be called such a principle of self-cleaning by shock washing the filter.

 The aim of the invention is to improve the self-cleaning of the filter by using at least part of the discharged medium from the pressure sections of the filtration system to control the filtrate for the removal of contaminants.

 This goal is achieved by the fact that in a system module containing at least one injection pump with a drive, an output and an input in communication with the output of the first connecting device having at least one input for supplying a filtered medium from system elements, also containing a self-cleaning filter with the slurry cavity and the cavity of the filtered medium communicated through the second connecting device with the outlet of the injection pump, and made with at least one outlet of the filtrate in communication with the device continuous or intermittent supply of the filtrate, which has at least one outlet for communication with at least one consumer, a device for removing contaminants from at least one self-cleaning filter, having at least one inlet connected to the sludge cavity, and at least one an output for communication through elements of the system with the input of the first connecting device, containing at least one adjustable choke, the input of which is in communication with the sludge cavity, and the output with the output of the pollution removal device, according to the invention, the device for removing contaminants is configured to control the parameters of the filtrate.

In addition, according to the invention, the self-cleaning filter can be made with the possibility of predominantly transverse washing of at least part of the tubular elements by the flow of the filtered medium or at least once they cross the filtered medium in the transverse direction. Then, according to the invention, the concentrate discharge cavity can be made with the cavity of the filtered medium, and the self-cleaning filter can be configured to realize filtration with at least two different directions relative to the filter surface of the tangential velocity component of the filtered medium. In addition, according to the invention, the system module may be arranged to clean the filter surface of the self-cleaning filter with reverse current of the filtrate.

In particular, according to the invention, the module is designed for an internal combustion engine used to operate under stochastic modes of changing the crankshaft rotational speed, moreover, the rotational speed of the crankshaft of the engine, above which the discharge pump capacity is greater than the filtrate flow rate required for the engine, does not exceed a frequency value that differs to a smaller side from the average operating value at least by the value of the standard deviation.

 Further, according to the invention, the device of a constant or intermittent supply of the filtrate can be made in the form of a shut-off valve, the input of which is communicated through a function-converting device with a control input of the pressure valve. Moreover, according to the invention, the shut-off valves for at least a portion of consumers can be configured to be in open or closed states. In addition, according to the invention, the discharge pump is designed with a capacity exceeding the total flow rate of the filtrate through all consumers. Moreover, according to the invention, the pressure valve can be made with a maximum throughput, not less than the maximum capacity of the discharge pump.

 Then, according to the invention, the pollution removal device may comprise at least one auxiliary filter, the inlet of which is communicated through the elements of the hydraulic and / or pneumatic networks, and / or pipeline elements and / or connecting channels with a pressure source, and the output with the output of the pollution removal device. In particular, according to the invention, the pressure source can be made in the form of an auxiliary pump with a drive. Moreover, according to the invention, the input of the auxiliary pump through the elements of the hydraulic and / or pneumatic networks, and / or the elements of the pipelines and / or connecting channels can be communicated with the output of the adjustable throttle, or with a slurry cavity. In addition, according to the invention, the pressure source can be made in the form of a slurry cavity.

 Further, according to the invention, the contaminant removal device may include at least one pressure pulsation damper in the system module, which can be connected to the input of the adjustable throttle, or communicated with the input of the auxiliary pump or with the input of the auxiliary filter. In the latter case, if the auxiliary filter is made in the form of a centrifuge with a jet drive of the rotor, then, according to the invention, the centrifuge can also be made with a vertical axis of rotation of the rotor containing in its upper part a dead-end air cavity, the input of which is connected to the input of the centrifuge.

 Then, according to the invention, the pollution removal device can be configured to at least partially separate the dissolved and / or undissolved gas phase from the dispersion medium. In addition, according to the invention, the dispersion medium of the filtered suspension can be a mixture of several liquids with different boiling points, and the device for removing contaminants can be made with the possibility of at least partial distillation of some of them. In particular, according to the invention, the centrifuge can be made with a cavity outside the rotor in communication with the outlet of the centrate, in addition, the cavity outside the rotor on the side of the centrifuge opposite the outlet of the centrate can be communicated through pneumatic network elements and / or piping elements and / or connecting channels with the atmosphere.

In addition, according to the invention, the centrifuge can be arranged to defoam the centrate.

 Further, according to the invention, a self-cleaning filter can be made with a hydrophobic filter surface.

 It is also possible according to the invention when the filtered medium is a suspension, the self-cleaning filter and the contaminant removal device are made in the form of a full-flow centrifuge with a jet rotor drive and a filter surface that extends along the axis of rotation of this rotor and separates the cavity of the filtered medium from the pressure outlet of the filtrate, s the cavity of the filtered medium and the slurry cavity, made at the same time in the form of an internal rotor cavity, located on the supply side of the filtered medium to the fixing surface, the input of the pollution removal device is combined with the indicated intracavity cavity, and the pollution removal device is made in the form of a rotor, the reactive drive of which is in communication with the cavity of the medium to be filtered, with the output made in the form of a pressure-free outlet of the centrifuge centrifuge, and the indicated rotor cavity is communicated through connecting channels in the rotor and in the centrifuge elements with an adjustable choke input, the control input of which is communicated through a function-converting device with the device constant or intermittent filtrate supply to the consumer under pressure.

 Then, according to the invention, it is possible when the filtered medium is a suspension, and the self-cleaning filter is made in the form of at least full-flow centrifuges with a jet rotor drive and with the possibility of alternately disconnecting them from the outlet of the discharge pump, the pressure outputs of the filtrate of which are interconnected, the filtering surface of the self-cleaning filter made inside the rotor of a full-flow centrifuge with a length along the axis of rotation of this rotor, a cavity of the filtered medium and a slurry cavity l are made at the same time in the form of a rotor cavity located on the supply side of the filter surface, and the pollution removal device contains an input combined with the specified rotor cavity, and is made in the form of a rotor, the reactive drive of which is in communication with the cavity of the filtered medium having an outlet, made in the form of pressureless centrifuge centrifuge exit, and, the specified rotor cavity is communicated through connecting channels in the rotor and in the centrifuge elements with an adjustable choke input, the control input of which It is communicated through a function-converting device with a constant device or with interruptions in the filtrate supply to the consumer under pressure.

 The system module 1 (Fig. 1) contains a pressure pump 2 with a drive 3, output 4 and input 5 connected to output 6 of the first connecting device 7 having an input 8 for supplying a filtered medium from the system elements, a self-cleaning filter 9 with a filter surface 10, sludge cavity 11 and cavity 12 of the filtered medium communicated through the second connecting device 13 with the outlet 4 of the injection pump, made with the outlet 14 (14 ') of the filtrate, connected with the device 15 (15') constant or with interruptions in the supply of the filtrate, which has od 16 (16 ') for communication with the consumer, the device 17 of the removal of contaminants having an input 18 in communication with the sludge cavity 11, and an output 19 for communication through system elements with input 8 of the first connecting device 7, containing an adjustable choke 20, the input 21 of which communicated with the slurry cavity 11, and the output 22 with the output 19 of the device 17 removal of pollution. The device 17 for removing contaminants is configured to control the parameters of the filtrate, in this case the filtrate flow, by programmatically changing the pressure at the outlet 4 of pump 2. This change is carried out by a function-converting device 23 containing an adder 24 for determining the error signal 25 as the difference between the driving signal 26 and the actual pressure level at the outlet 4 of the pump 2, supplied through the channel 27 to the second input of the adder 24, and also containing the device 28 for generating a signal 29 of the executive air acting on the adjustable throttle 20. In general, the function-converting device 23 may provide any desired control of the adjustable throttle depending on what software change in pressure at any point of the module or filtrate flow rate at the output 16 (16 ') is required. For the simplest task, when the control of the filtrate parameters is reduced to stabilization, for example, the constant pressure set by the signal 26 at the output 4 of the pump 2, the actuating signal 29 is simply proportional to the control error 25. In this case, the filtrate flow is controlled by static pressure control at the pump 2 output , which is a typical solution, for example, for lubricating oil filtration systems of internal combustion engines (ICE).

 In FIG. Figure 2 shows an example of the use of a system module as part of an engine oil filtration system. The output 19 of the contaminant removal device 17 is communicated with the input 8 of the first connecting device 7 through system elements such as a pipe 30, a filtered oil tank 31 and a pipe 32, and the output 16 of the filtrate supply device 15 is communicated with the filtrate consumer 33, in this case, the elements ICE internal lubrication system.

 The system module operates as follows.

 The medium to be filtered comes from the system elements to the input 8 of the first connecting device 7 and is pumped 2 through the second connecting device 13 into the cavity of the filtered medium 12 of the self-cleaning filter 9, passing through the filtering surface 10, it is fed from the outlet 14 through the filtrate feed device 15 to the output 16, communicated with the consumer 33. The device for the removal of contaminants 17 controls the parameters of the filtrate, in particular the flow rate, for example, by stabilizing at a given pressure level at the output 4 of the pump 2, reset sucking from the sludge cavity 11 an excessive amount of pressure medium. Since the flow of discharged medium is added to the standard flow rate of the medium spent on the removal of contaminants from the filter 9, this improves the self-cleaning of the specified filter, for example, in the case of washing the filter by countercurrent.

 In the simplest embodiment, the adjustable throttle 20 can be made in the form of a pressure valve with its own control (direct acting valve, Fig. 3). In this case, the filtrate parameters are controlled by, for example, stabilizing the pressure in the slurry cavity 11 of the filter 9.

 The valve 20 may have a control input 29 communicated through a function-converting device 23 with any pressure section of the module, in particular, with the output 4 of the pump 2 (Fig. 4) or with the filtrate feed device 15, for example, with the output 16 (Fig. 5) . The latter case reflects the process of controlling such a filtrate parameter as the pressure at the outlet of the filtrate supply device.

 If there are several consumers and one of them is farthest from the filtrate outlet 14, then it is advisable to change the flow area of the controlled valve 20 depending on the pressure at the outlet of the filtrate supply device to this most distant consumer. An example is the internal ICE lubrication system, some of which are represented by crankshaft bearings. Oil is supplied to these bearings from the filtrate supply device, made in the form of a distributing manifold, the front entrance of which is connected to the output of the filtrate 14 from the filter 9. The most distant is the bearing, to which the filtrate is supplied from the outlet 16, located on the opposite end of the manifold . In this case, it is advisable to control the filtrate pressure at the most distant outlet 16.

 Leachate consumers can be ranked by importance. In this case, it is advisable to control the filtrate parameters for the most significant consumer.

 If the filtrate parameters are controlled by programmatically controlling the pressure in any pressure section of the module (a special case is pressure stabilization), then it is advisable to use a channel 34 (Fig. 6) of constant cross section, the value of which is selected from the provision proper quality of transients in the pressure regulation system. In this case, the functional transformation is reduced to the conversion with a transmission coefficient equal to one of the pressure feedback signal, and the choice of the channel cross-section ensures the necessary damping of the feedback, which increases the stability of the control system and makes transient processes aperiodic under pulsed disturbances (E. Shutkov Development of methods for hydraulic calculation of external lubrication systems and oil filters of forced diesel engines: Abstract of thesis for the degree of candidate of technical sciences, M. 1984, p. 228) .

 The simplest case of controlling the parameters of the filtrate using a controlled valve 20 is the use of a valve with constant adjustment of the pressure at which it starts to operate.

 The self-cleaning filter 9 is usually made with a slurry cavity 11 communicated continuously or intermittently with at least part of the cavity of the filtered medium 12. Figures 7 and 8 show a filter in which the slurry cavity 11 is periodically communicated using a distributor 35 driven by a drive 39 through the channels 37 and 38 with that part of the cavity 12, which is located inside the sector 39, included in the backwash of the filtrate. The remaining seven sectors 40 operate at this time in the mode of filtering the medium supplied to the remaining part of the cavity 12. In FIG. 9 shows a self-cleaning filter with a slurry cavity 11, which is in constant communication with the cavity of the medium to be filtered 12. This design of the filter improves the process of controlling the parameters of the filtrate, eliminating the throttling effect from the side of the distributor 35 in FIG. 7, since the sludge cavity of the filtered medium constitutes in this case one common cavity.

 Shown in FIG. 9, the filter is configured to tangentially filter part of the filtered medium adjacent to the boundary layer on the filtering surface 10. The remaining part of the filtered medium is used to carry out the washed away contaminants into the sludge cavity 11, which in this case is the drainage cavity of the concentrate. Activation of the transit flow of the filtered medium when used to control the filtrate parameters improves the self-cleaning of the filter by increasing the tangential component of the medium velocity on the filter surface.

 An even greater effect can be achieved by using a tangential filter (Fig. 10) with a surface formed by tubular filter elements, for example, hollow fibers, the space between which is communicated with the cavity 12 of the filtered medium. The tubular filtering surface enhances the turbulization of the medium in the annulus, especially during transverse washing of the fibers, and thereby improves the washing of the surface with a transit stream. The use of this stream with multiple intersection of fibers in different directions (Fig. 11) eliminates stagnant zones in the cavity 12 and improves self-cleaning when forcing a transit stream during the process of controlling the filtrate parameters.

 In FIG. 12 shows the use of a module with a self-cleaning filter, configured to implement filtering with two different directions of the tangential component of the velocity of the filtered medium relative to the filter surface. In this filter, the cavity of the filtered medium 12, combined with the slurry cavity 11, is in communication with the second connecting device 13 through the channel 41 and channel 42. The interaction of the two flows of the filtered medium improves the cleaning of the filtering surface 10 by increasing the turbulization of the boundary layer.

 The best method of self-cleaning the filter is a method of washing with reverse flow of the filtrate. In FIG. 13 shows a module with the possibility of such regeneration of a self-cleaning filter. An even greater effect can be achieved by using a tangential filter with the possibility of washing it with reverse current of the filtrate. The self-cleaning filter is made in the form of two filters 9 and 9 ', the filter medium cavity of which 12 and 12' is connected alternately by the second connecting device 13 to the output 4 of the pump 2. In this case, the device 13 is made in the form of a three-way valve 43 with a drive 44. Each of the filters has sludge cavity 11 (11 '), in communication with the corresponding device 17 (17') removal of contaminants. When the filters 9 and 9 'are in any of the modes, the indicated devices for removing contaminants control the filtrate pressure at the outlet 16 of the filtrate supply device 15 to the consumer 33.

 The first 7 and second 13 connecting devices, as well as a device with a constant or intermittent feed of the filtrate 15, can be made in the form of hydraulic and / or pneumatic networks and / or pipe elements and / or connecting channels, contain pipe fittings or at least one discharge pump. Figures 14 and 15 show examples of such versions of the module. In FIG. 14, the first connecting device 7 is made in the form of a filter 45, connected to the input 8 of the connecting device by a pipe 46 and to the input 5 of the pump 2 by a pipe 47. The second connecting device 13 is made in the form of a pipe 48. The filtrate feed device 15 is made in the form of interconnected one of known methods of the temperature controller 49 and heat exchanger 50, communicated through a protective filter 51 with the output 16 of the device 15. In FIG. 15, the first connecting device 7 is made in the form of a suction filter 45, a pressure pump 52, a heat exchanger 50 and a temperature controller 49 connected by a pipe 47 with an input 5 of a pressure pump 2 and a pipe 46 with an input 8 of a connecting device 7. The second connecting device 13 is made in in the form of a pipeline 48. The filtrate feed device 15 is made in the form of a protective filter 51 in communication with the output 16 of the device 15.

 If the filtered medium is diesel fuel, the filtrate of which is designed to be supplied to the elements of the diesel fuel injection equipment, and the injection pump is driven by this diesel, then the system module can be made as shown in FIG. 16. In this figure, the self-cleaning filter is made in the form of several tangential filters, moreover, the cavity of the filtered medium 12 of the filter 9 is communicated through the second connecting device 13 with the outlet 4 of the pump 2, and the sludge cavity 11 through the pipe 53 of the pollution removal device 17 with the cavity 12 'being filtered of the filter medium 9 ', the slurry cavity 11' of the filter 9 'is communicated through the conduit 54 of the contaminant discharge device 17 with the cavity of the filtered medium 12' 'of the filter 9' ', while the slurry cavity 11' 'of the filter 9' 'is in communication with the inlet 21 of the pressure head valve 20 , in this case, a valve with its own control (direct action). The concentrate stream of the previous filter is a stream of suspension to be filtered for the subsequent one. In FIG. 17 and 18 explain in detail the principle of operation of the system module with the serial connection of two filters in the flow of concentrate.

 In FIG. 17, the system module in addition to the discharge pump 2 contains a first connecting device 7, made in the form of a safety filter 45, connected to the input 8 of the connecting device 7 and to the input 5 of the pump 2, the second connecting device 13, made in the form of a fine filter 55, which communicates the cavity the filtered medium 12 of the tangential filter 9 with the output 4 of the pump 2, the tangential filter 9, made at the same time with the device for the pulsed supply of the filtrate 15 to the consumer - elements of the fuel injection device diesel engine, moreover, the sludge cavity 11 of the filter 9 is communicated by the channel 53 of the pollution control device 17 with the cavity of the filtered medium 12 'of the same filter 9', and the slurry cavity 11 'of the filter 9' is communicated through the channel 57 of the pollution control device 17 and the ripple damper 58 with an input 21 of the pressure valve 20, the output of which 22 is in communication with the output 19 of the contaminant removal device 17. The output 19 is communicated through a system pipe 30, a fuel tank 31 and a pipe 32 with an input 8 of the first connecting device 7. The impulse filtrate device 15 (FIG. 18) is made in the form of a high pressure fuel pump (TNVD), the housing of which is combined with the housing of the tangential filter 9. The latter is made in the form of the filter shown in FIG. 9. The outlet of the filtrate 14 is combined with the cavity 59 of the injection pump, from which the filtrate enters the plunger sleeve 60 through the holes in the sleeve 61 and 62. Inside the sleeve 60 is a movable plunger 63, which provides a pulsed fuel supply to the outlet 16 of the injection pump. Output 16 is in communication with the fuel injector.

 The system unit operates as follows.

 The medium to be filtered is sequentially cleaned in filter 45 with a screening fineness of 80-100 microns, in filter 55 with a screening fineness of 30-40 microns and in filters 9 and 9 'with a screening fineness of 1-2 microns. The tangential filters 9 and 9 'are washed with a transit stream of filtered fuel, and the device for removing contaminants 17 through the outlet 19 discharges washable contaminants into the fuel tank 31. The device controls the filtrate parameter, such as the filtrate pressure in the injection pump chamber 59, using the pressure valve 20. So that the contaminations of the filtering surface of the self-cleaning filter 10 (10 ') have the least influence on the process of controlling the filtrate parameters, the system module is configured to flush the tangential filters 9 and 9' with a reverse current of the filtered liquid. The flushing is carried out in the fuel cutoff mode by the plunger 63, when the high pressure cavity 64 in the high-pressure fuel pump 15 communicates with the cavity 59 (Fig. 18). At this time, a pressure pulse arises in the cavity 59, exceeding the pressure in the cavity 11 (11 ') of the self-cleaning filter, as a result of which the filtrate flows back through the filtering surface 10 (10'), washing away the contaminants. The pressure pulsation damper 58 senses an excess of the medium that entered the cavity 11 (11 ') in a pulsed mode, which, together with the pulsation damping, improves the dirt removal. The delivery of the injection pump usually exceeds the filtrate consumption, therefore, adding to the reverse self-cleaning stream an intensive transit stream through all the tangential filters used to control the filtrate pressure improves their self-cleaning.

 An even greater effect is achieved when the module of FIG. 19. The module contains, along with the injection pump 2, a first connecting device 7, made in the form of a series-connected protective filter 45 and a heater 65, connected with the input 8 of the connecting device and with the input 5 of the pump 2, the second connecting device 13, made in the form of a fine filter 55, communicating the output 4 of the pump 2 with a cavity 12 and 12 'of tangential filters 9 and 9', made integral with the corresponding high-pressure fuel pumps 15 and 15 ', moreover, the cavities 12 and 12' of the filters 9 and 9 'are interconnected via a pipeline 56, and tap cavity the concentrate 11 and 11 'are interconnected via a contaminant discharge device 17 pressure pulsation dampers 58 and 58' and a pipe 66 and are also connected to the inlet 21 of the pressure valve 20. The output 19 of the pollution control device 17 through the elements of the system (pipeline 30, tank 31 and pipeline 32) with the input 8 of the first connecting device 7. In this version of the module, the self-cleaning of the filters 9 and 9 'is improved due to the fact that the filters operate under the same pollution conditions.

 If the medium to be filtered is lubricating oil, the filtrate of which is intended to be supplied to the internal combustion engine internal lubrication system and the injection pump is driven by this engine, then the system module can be used as a component of the internal combustion engine lubrication system. Examples of such application of the module are shown in figures 14 and 15. In FIG. 14 depicts a variant of a lubrication system with a single discharge pump, in which the contaminant discharge device 17 controls the filtrate pressure at the outlet 16 of the filtrate supply device 15 to the internal engine lubrication system 33. In this case, the control stabilizes the pressure at a predetermined level regardless of the influence of such factors, as a change in the performance of pump 2 with a change in the frequency of rotation of the crankshaft of the engine, a change in the viscosity of the oil with temperature variations, and also the degree of contamination of the filter surface and 10 of the filter 9. In this case, the medium discharged from the system when controlling the pressure of the filtrate is used to force self-cleaning of the filter 9, which improves its regeneration. In FIG. 15 shows another embodiment of the module, in which, for unloading the injection pump 2, some of the components of the lubrication system (thermostat 49 and heat exchanger 50) are brought into the circuit of another pump 52. The advantage of this scheme is a lower pressure level at the outlet of the pump 2 and, as a result, improved Conditions for controlling the filtrate parameters with oil pressure in front of the engine 33.

 With the wear of the internal combustion engine during its operation, the resistance of the internal engine lubrication system decreases due to an increase in the gaps in the friction pairs. Therefore, to ensure the desired pressure at the inlet of the filtrate into the engine for the entire life of the engine, the injection pump 2 is always designed for greater productivity than the filtrate consumption required by the engine 33. As a rule, the discharge from the pressure circuit of the lubrication system of the excess medium begins with a certain value of the crankshaft speed and above. From this value of the rotational speed, the process of controlling such filtrate parameters in the system module begins, such as, for example, the pressure at the outlet 16 of the filtrate supply device 15. The indicated frequency is always higher than the starting crankshaft rotation frequency and most often closer to the nominal. The engine can be made to work under stochastic modes of changing the crankshaft speed, which in most cases takes place in practice. For such an engine, it is advisable that the rotational speed of the crankshaft, above which the discharge pump capacity is greater than the filtrate consumption required for the engine, does not exceed a frequency value that differs to a lesser extent from the average operating value by at least the mean square deviation. Fulfillment of this condition in the case of the normal law of distribution of loading modes guarantees the use of the capabilities in the system module for at least 84% of all loading modes.

 The device is constant or with interruptions in the supply of the filtrate 15 (Fig. 20) can be made in the form of a shut-off valve 67 (valves), for example, for the case of using the module as part of a cleaning system of cutting fluid (coolant) with one or more consumers of the filtrate 33. Moreover, part (or even all) of the consumers can be simultaneously shut down from work with the complete closure of the corresponding valves. If the control input of the pressure valve 20 is in communication with the input of each of the valves 67, then, as consumers turn off or turn on the pollution removal device 17, it will control the filtrate parameters so that the filtrate pressure at the entrance to each valve 67 is equal to the set value. The injection pump 2 must be performed with a capacity exceeding the flow rate of the filtrate by all consumers 33, in order to provide the ability to control the parameters of the filtrate when all consumers are switched on at the same time. In the case of simultaneous shutdown of all consumers, the device for removing contaminants 17 will create the greatest flow rate through the pressure valve 20, thereby providing the most forced self-cleaning mode of the filter 9 with simultaneous control of pressure (stabilization) at the inlet of the shut-off valve 67. At the same time, the discharge valve 20 should be made with maximum throughput in excess of the maximum capacity of the discharge pump 2, to avoid overloading the pump 2 in pressure.

 The module can be made with a device for removing contaminants, containing at least one auxiliary filter, the input of which is communicated through elements of hydraulic and / or pneumatic networks, and / or elements of pipelines, and / or connecting channels with a pressure source, and the output with the output of the exhaust device pollution. In particular, the pressure source (Fig. 21) can be represented by an auxiliary pump 68 with an actuator 69. The inlet 70 of the pump 68 is connected through the pipe 71 to the output 22 of the pressure valve 20, and the output 72 through the pipe 73 is connected to the input 74 of the auxiliary filter 75, , the output 76 of the auxiliary filter 75 is communicated with the output 77 of the pollution removal device 17. The use of the module in the embodiment of FIG. 21 makes it possible to utilize the contaminants discharged from the sludge cavity 11 of the self-cleaning filter 9, thereby reducing the filtration load on the filter 9, improving its self-cleaning and facilitating control of the filtrate parameters.

 The inlet 70 of the auxiliary pump 68 can be communicated, for example, through a pressure pulsation damper 58 with a slurry cavity 11 of the filter 9 (Fig. 22). Such a solution is advisable when the system module most of the time works with a closed pressure valve 20.

 The pressure source for supplying the auxiliary filter 75 (Fig. 23) can be made in the form of a slurry cavity 11 of the filter 9. In this case, the inlet 74 of the filter 75 can be in communication with the cavity 11, for example, through a pressure pulsation damper 58. The advantages of this solution compared with the previous - the lack of energy costs for the drive of the auxiliary pump 68.

 The best design solution for the disposal of discharged contaminants is to use a centrifugal cleaner as an auxiliary filter 75, which does not require replacing the used filter elements. If the filtered medium is a suspension, then the centrifugal cleaner can be made in the form of a centrifuge with a jet rotor drive, the input of which can be connected to the input of an adjustable inductor 20, or it can be made with a rotating rotor driven by an electric motor. In the latter case, the drive of said rotor and the drive of the auxiliary pump can be combined, as shown in FIG. 24. In FIG. 24 shows a typical external lubrication system for a marine diesel engine power plant, in which the inventive system module is used as a component of the system. The features of the specified module execution are as follows. The filtrate supply device 15 contains, in addition to the hydraulic network elements and pipeline elements described above, a dispensing manifold 78, an end inlet 79 of which is communicated through a protective filter 51, a heat exchanger 50 and a temperature regulator 49 with an outlet 14 of a self-cleaning filter 9. The opposite end 80 of the collector 78 is communicated through a channel 34 s the control input of the pressure valve 20. The device 15 has several outputs 16, made in the form of the outputs of the collector 78, for communication with the elements 33 of the internal lubrication system of the diesel 81. The device 17 for retraction the filter contains an auxiliary filter 75, made in the form of a centrifugal cleaner with a rotating rotor, the drive 69 of which is combined with the drive of the auxiliary pump 68, the input 74 communicated through the heater 65 with the output 72 of the auxiliary pump 68, and the output 76 communicated with the output 77 of the pollution removal device 17, and the inlet 70 of the pump 68 is communicated through a safety filter 45 ', a pipe 82, a container 31 and a pipe 30 with the output 19 of the pollution removal device 17. The advantage of this module is the possibility of organization of better utilization of contaminants and better oil cleaning using a centrifugal cleaner and, accordingly, the possibility of improving the self-cleaning of filter 9 in the process of controlling the filtrate parameters.

 If during the filtration of the suspension the contaminant removal device contains a pressure pulsation damper 58 of the pumped medium (figures 17, 19, 22 and 23), this stabilizes the adjustable filtrate parameters, facilitates not only their control, but also determines the self-cleaning process of the filter 9. In this case, the indicated the process can be forced in accordance with the law adopted to control the parameters of the filtrate without the influence of stochastic pressure pulsations. Damping of pulsations by means of an oscillation damper also has a positive effect on the operation of, for example, a centrifuge with a jet rotor drive used as an auxiliary filter 75, on the operation of the pressure valve 20 or auxiliary pump 68, especially when the damper is in communication with the inputs of these units. The simplest version of a pressure pulsation dampener is shown in FIG. 25, where the auxiliary filter 75 is made in the form of a centrifuge with a jet drive 83 of the rotor 84. The rotor 84 is mounted on a vertical axis 85, which is made with a dead-end air cavity 86. The inlet 87 of this cavity is in communication with the inlet 74 of the centrifuge 75. With sudden changes in fluid pressure in The cavity 86 receives from the system excess fluid or makes up for its deficiency, thereby reducing the amplitude of the pulsations and facilitating the operation of the pressure valve 20, which in this case is integral with the centrifuge 75.

 The self-cleaning of the filter 9 also improves with the degassing of the dispersion medium or with at least partial gas separation, since a decrease in the gas content in the liquid medium increases its density and increases the shear stresses in the boundary layer of the tangential filter 9, or increases the velocity pressure on the particles of contaminants when washing the filter surface reverse current filtrate. In addition, the degassing of a liquid reduces its compressibility, which facilitates the process of controlling the dynamic parameters of the filtrate, and therefore, as indicated above, improves the self-cleaning of the filter 9. The presence of easily boiling liquid components in the filtered liquid also destabilizes the self-cleaning process, since it saturates the main dispersion medium released from such components in pairs. Distillation during operation of the boiling components will improve self-cleaning as well as liquid degassing.

 In FIG. 25 shows a centrifuge with a jet rotor drive, which can be used to control a filtrate parameter such as steam or gas content. The centrifuge 75 is made with a cavity 88 outside the rotor 84, communicated with the exit 76 of the centrate. The specified cavity on the side 89, opposite the outlet 76 of the centrate, is also communicated through the pipe 90, the filter-moisture separator 91 and the pipe 92 with the atmosphere. In addition, a screw thread 93 is made on the cylindrical surface of the rotor 84, and an antifoam mesh 94 is installed between the jet drive 83 and the output of the centrate 76. The rotor 84 is rotatably mounted on two plain bearings 95 and 96 together with a column 97 which is stationary relative to the rotor. The axis 84 is made with holes 98 (98 ') for the passage of the liquid being scanned into the cavity 99, and then through the holes 100 (100') in the column 97 into the cavity 101 of the rotor 84.

 The centrifuge 75 operates as follows.

 The suspension containing the dissolved and / or undissolved gas phase, under pressure, enters the inlet 74, its excess is discharged by the pressure valve 20 in accordance with the magnitude of the control signal through the channel 34, and the rest of the liquid enters through the openings 98 (98 ') in the axis 85, cavity 99 and holes 100 (100 ') in column 97 into cavity 101 of the rotor. On this way, a part of the bubbles of undissolved gas is separated by the fluid inlet 98 (98 ') and enters the air cavity 86, the other part, which leaked through the gap in the bearings 95 and 96, into the extra rotor cavity 88. The main part of the bubbles is fugged in the cavity 101 during rotation the rotor 84, pushing toward the column 97, and is carried out by the flow of the suspension into the nozzles of the jet drive 83. Bubbles, having entered the cavity 88 with reduced pressure, increase in volume and are retained by the defoamer net 94. At the same time, part of the liquid leaked through the hny bearing 95, the rotor is thrown onto the inner surface 102 of the cap 103 through which flows down as a thin film. When the rotor 84 is rotated due to the screw thread 93, a vapor-gas medium is created in the cavity 88 with a direction along the axis 85, depending on the direction of the screw of this thread. In this case, the vapor-gas mixture is displaced towards the filter-moisture separator 91, after which it enters the atmosphere. The countercurrent movement of this mixture with respect to the direction of movement of the centrate creates favorable conditions for defoaming on the net 94 and degassing the liquid film on the surface 102 of the cap 103. In contrast, the direct flow movement better stabilizes the film on the surface 102.

 The suspension can be fumigated by heating it or by heating the cap 103 of the centrifuge 75 (not shown), which not only facilitates the degassing of the dispersion medium, but also allows for the distillation of easily boiling liquid components having a lower boiling point than the base dispersion medium. In particular, if the filtered medium is flooded diesel oil or fuel, then the centrifuge of FIG. 25 allows the purification of such a medium with water separation. Obviously, the control of such a filtrate parameter as water content with the help of this centrifuge is facilitated if the self-cleaning filter 9 is made with a hydrophobic filter surface.

 When the medium to be filtered is a suspension, the module may comprise a self-cleaning filter 9 made with a contaminant removal device 17, as shown in figures 26 and 27, in the form of a full-flow centrifuge 9 with a jet drive 83 of the rotor 84 and a filter surface 10 of a type, for example, mesh the cylinder surrounding the column 97. The surface 10 separates the cavity 12 of the filtered medium from the pressure outlet 14 of the filtrate. The cavity of the filtered medium 12, the slurry cavity 11 and the input 18 of the pollution removal device are integral at the same time in the form of an inner-rotor cavity 101 located on the supply side of the filtered medium to the filter surface 10. The pollution removal device 17 is made in the form of a pressure valve 20 and a rotor 84, a jet drive 83 which is communicated with the cavity 101 (12, 11, 18) of the filtered medium. The specified cavity 101 (12, 11, 18) is communicated through holes 100 (100 ') in column 97, cavity 99, holes 98 and 98' in the fixed axis 85 and channels 104 and 105 with the inlet 21 of the pressure valve 20. The control input of the valve 20 communicated through channel 34 to the outlet 16 of the filtrate supply device 15 to the consumer 33 under pressure. The exit of the centrate from the rotor 84 is communicated through channel 106 with the outlet 19 of the contaminant removal device and with the outlet 22 of the pressure valve 20. The filtrate outlet 14 is communicated through the channel 107, openings 108 in axis 85, cavity 109, openings 110 and 110 'in the same axis and holes 111 and 111 'in a column 97 with a cavity 112 on the filtrate side of the filter surface 10. The output 19 of the pollution removal device is communicated through a pipe 30, a container 31 and a pipe 32 with an input 8 of the first connecting device 7.

 The module depicted in FIG. 28, operates as follows.

 Filtered medium from the tank 31 through the pipe 32 is supplied to the input 8 of the first connecting device 7 and then to the input 5 of the pump 2, from where it is pumped under pressure through the second connecting device 13, channels 105 and 109, openings 98 and 98 ', cavity 99 and openings 100 and 100 'into the cavity 101 (12, 11, 18) of the rotor 84. Part of this suspension enters the jet drive 83, rotating the rotor 84, and the other part passes through the filtering surface 10 into the cavity 112 and then through the holes 111 and 111', 110 and 110 ', cavity 109, hole 108, channel 107, filter feeder rata 15 to the output 16 of this device. As the filter surface 10 becomes dirty and the pressure drop on it increases, the pressure at the outlet 16 of the filtrate supply device 15 will decrease, since the increase in pressure in the cavity 101 (12, 11, 18) increases the fluid flow through the jet drive 83. The pressure drop of the filtrate relative to a given value which pressure valve 20 is tuned to causes a decrease in pressure along the channel 34 of the control input of the valve and, accordingly, a decrease in the flow area of this valve along the executive input 21. This leads to a decrease in discharge excess medium from the centrifuge channel 105 and to increase the flow rate of liquid through this filter, which further increases the pressure in the cavity 101 (12, 11, 18). Accordingly, the flow rate of the liquid through the jet drive 83 increases, which leads to an increase in the rotational speed of the rotor 84 and an increase in the separation factor in the centrifugal field. The filter surface 10 is cleaned of impurities, followed by the restoration of the filtrate pressure at the outlet 16. Thus, the contaminant removal device, consisting of a rotor 84 and a pressure valve 20 with remote control, controls the filtrate pressure, improving the self-cleaning of the filter 9 by using it to remove impurities ( joint) parts of the discharged medium from the pressure circuit of the filtration system in the process of controlling the pressure of the filtrate.

 The effect of improving self-cleaning of the indicated full-flow centrifuge can be enhanced by adding the possibility of washing the filter surface 10 with reverse current of the filtrate. The module implements this idea according to the circuit depicted in FIG. 28. The module contains a self-cleaning filter made in the form of two filters 9 and 9 ', the design of each of which is shown in FIG. 26 and 27. The cavities 101 and 101 'of the filtered medium of these filters are alternately communicated by means of a second connecting device 13 with the output 4 of the pump 2. The device 13 is made in the form of a three-way valve 43 with a drive 44 and the corresponding pipelines. The outputs 14 and 14 'of both filters are interconnected via pipelines 113 and 113'.

 The module works as follows.

 When the filter 9 'is disconnected from the output 4 and the filter 9 is connected to this output, the latter works as described above for FIG. 26. A part of the filtrate is discharged from the outlet 14 of the filter 9 operating for full-flow cleaning to the outlet 16, and the other part through the pipe 113 'enters the filter 9', rinses the filtering surface 10 'with reverse current and enters the jet drive 83', providing rotation of the rotor 84 '. Washed impurities settle inside the rotor 84 ', and the centrate ejected by the jet drive 83' is discharged through the pipeline 106 'to the exit 19'. Moreover, some of the backwash flow from the inner cavity 101 '(Fig. 26) through the holes 100 and 100', the cavity 99, the holes 98 and 98 'and the channels 104 and 105 enters the inlet 21' (Fig. 28) of the valve 20 ' whose opening value is controlled by channel 34 '. Adding this part of the medium to the part that goes to the jet drive 83 'improves the cleaning of the surface 10'.

 When the tap 43 is switched, the operation of the filters 9 and 9 'changes to the opposite: the filter 9 is switched on in the reverse filtrate washing mode, and the filter 9' is switched on in the full-flow filtration mode.

 Thus, the part of the liquid spent to control the parameters of the filtrate (in this case, the pressure at the outlet 16) is used to remove impurities from the self-cleaning filter, improving the regeneration of its filter surface 10.

 The patented system module, which implements the principle of shock flushing of a self-cleaning filter, opens up new possibilities for creating coolant regeneration systems using only automated filters. An example of such a filtering system is shown in FIG. 29. The diagram shows a bench system for precision liquid filtration, including the patented module. In addition to the components already described, the module contains a self-cleaning filter made in the form of two tangential filters 9 and 9 'with hydrophobic filtering surfaces of precision cleaning 10 and 10', respectively. Their slurry cavities 11 and 11 'are in communication with the contaminant removal device 17, which contains an auxiliary filter 9' 'made in the form of two full-flow centrifuges placed in a common housing 9' 'with a common pressureless outlet of the centrate on the pipeline 106. The design of the centrifuges is similar to that shown on FIG. 26. Their 10 '' and 10 '' 'filter surfaces are made of woven metal mesh and are designed for coarse filtration of the medium. The pressure outputs 14 '' and 14 '' 'of the filtrate of these centrifuges are connected through valves 113 and 113' to each other and through output 114, pipe 116 and valve 117 with output 16 '. The output 114 of the contaminant removal device 17 is also communicated through a valve 115 with a capacity 31 of the filtered liquid, an exit 16 with a capacity 32 of the liquid that has passed the precision cleaning, an output 16 'with the capacity of the 33' fluid that has passed the rough cleaning.

 The module works as follows.

 With closed valves 15 and 117 and open valves 113, 113 'and 115, we obtain a module according to the scheme described above and shown in FIG. 20, and with closed valves 15 and 115 and open valves 113, 113 'and 117, the module according to the circuit shown in FIG. 28. Both of these cases correspond to a rough cleaning of the liquid from solid particles and, possibly, from water, as well as from the gas contained in the liquid (not shown).

 With open valve 15 and closed valves 113, 113 ', we obtain a module according to the circuit shown in FIG. 13, with a device 17 for removing contaminants containing auxiliary filters in the form of these centrifuges. This case corresponds to the precision cleaning of the liquid with hydrophobic tangential filters 9 and 9 '.

 The most effective mode of operation of the module corresponds to the case when the valves 15, 113 and 113 'are open and the valves 115 and 117 are closed. This mode allows the regeneration of not only filters 9 and 9 ', but also reactive centrifuges with rotors 84 and 84'.

 Self-cleaning filter 9 can be made in a common housing with a discharge pump 2, in which the second connecting device 13 is made in the form of a channel (not shown). If the first connecting device 7 is made in the form of a suction pipe of the pump 2 with an input 8, and the output 22 of the adjustable inductor 20 is communicated with this input through a system element made in the form of a channel (not shown), then this solution reduces the load on the pump bearings 2 due to the lower pressure loss at the output of the specified pump.

 In the course of patent research, no analogues were found that coincided in their features with the distinguishing features of the present alleged invention, in view of which it meets the criterion of "novelty."
