Description

The invention relates to equipment for the preparation of modified bitumen (organic binders) and can be used, in particular, in the road industry.

The development of installations for the preparation of modified organic binders solves a number of technical problems, one of which is to reduce the preparation time of the product while maintaining its quality, as well as the creation of compact installations that are convenient for transporting and storing the product with further supply to the system of asphalt concrete plants.

The following settings are known from the prior art.

In the description of the patent document ES 2063606 (published 01/01/1995) disclosed installation for the modification of bitumen, characterized by the possibility of transportation due to the placement of appropriate equipment on the platform. The installation is a technologically related means, in particular, two reactors, each of which is equipped with two mixers for uniform mixing of the modifier and bitumen feed stream, also a heat exchanger, a pump system, a polymer dispenser with a mixer.

The known installation is characterized by high material consumption due to the need to use a wide range of equipment, as well as the complexity of installation and, as a result, low operational reliability.

The patents of the same copyright holder RU 2152474 (published on 07/10/2000) and RU 37727 (published on 05/10/2004) describe modifications of the same plant for the production of modified bitumen, which includes two reactors (each of the mentioned reactors is equipped with a screw and frame mixers, associated with the planetary carrier), as well as pumps for pumping the finished product, made in the form of dispersers - rotary devices - with modulation of the flow, which are installed on the pumping line of the finished product of each of the mixers and are connected to these mixers by recirculation pipelines. In addition, the installation includes dosing devices, a plasticizer storage hopper connected to a dosing screw, which, in turn, is connected to a device for feeding and dosing material into the reactor vessels.

The device known from the above two patents, solving the problem of increasing productivity, as well as the previous installation (ES 2063606), is characterized by a high material consumption of the equipment, the complexity of design and installation, and low operational reliability.

In the description to the patent RU 114324 (published on 20.03.2012) a plant for bitumen modification is disclosed, including a mixing reactor for bitumen modification, equipped with mechanical agitators and having a loading hatch, in addition, a circulation circuit for a liquid mixture of bitumen and an additive in the form of rubber crumb using bitumen pump, heating system. In this case, the mixer reactor is made in the form of a horizontally oriented container. The known plant also contains a mixing hopper for ozonating rubber crumb, equipped with a loading device and an unloading-reloading device, also connected to the mentioned mixing reactor for modifying bitumen. The unit is connected to the heating system. All units of the installation are connected to the process control and management system, which is introduced into the control cabinet. The mobility of the plant is ensured by placing all the equipment in a standard shipping container.

Known installation solves the problem of reducing the size and increasing mobility. However, this device is not without some limitations.

In view of the fact that rubber crumb is used for the preparation of modified bitumen, a hopper-mixer for ozonizing the specified material was introduced into the plant, which is technologically connected with the corresponding equipment. Consequently, the analyzed installation is characterized by limited use in terms of the material used, increased material consumption due to the presence of a wide range of equipment, installation complexity, and low operational reliability.

From the description of the patent RU 131737 (published on 27.08.2013) a plant for the preparation of modified rubber-bitumen mastics is known, including a reactor equipped with agitators for producing a mixture of bitumen and rubber crumb, associated with the first heater. In this case, the reactor is connected via a pipeline to an intermediate tank designed for mixing tar and additives, for example, polymers, rubber. The process mixture in the intermediate vessel is subject to heating using the second heater, and after reaching the specified temperature in the second vessel, the pipeline valves are opened and the pump returns the mixture obtained in the intermediate vessel to the reactor. The installation also includes pipelines for the circulation of the process mixture. The equipment is mounted on the vehicle trailer frame; the plant is made with a process control device.

The presence of an intermediate vessel associated with the reactor gives rise to the problem of increasing the time of the technological cycle of product preparation. In addition, for the same reasons as the above analogues, this installation is characterized by increased material consumption, installation complexity, and low operational reliability.

As the closest analogue, the installation from the description to the patent RU 2525487 (published on August 20, 2014) was chosen, which is a modification of the installation according to the patent RU 131737 (both patents issued to the same copyright holder) with the difference that only polyethylene is loaded into the additional container, and bitumen and rubber crumb enter the specified container from the reactor by gravity, and to prepare the product due to the presence of the pump, the resulting mixture is recirculated through the reactor for 1.5-2 hours.

The installation according to patents RU 131737 and RU 2525487 is not intended to use other raw materials than rubber crumb due to the limitation of the functionality of the mixers installed in the reactor and additional capacity. This factor indicates the lack of universality of the installation in relation to the raw materials used.

Thus, the installation according to patent RU 2525487 is characterized by:

- the duration of the technological process preceding recirculation for 1.5-2 hours, due to the need to heat the reactor, mix bitumen and rubber crumb in the reactor, in addition, an additional tank is heated, and then a mixture of bitumen and rubber crumb is transferred into this tank by gravity;

- high power consumption in the presence of two heaters;

- material consumption due to the use of a wide range of equipment;

- the complexity of installation and low operational reliability.

So, the proposed invention is aimed at solving the technical problem, which consists in creating a plant for modifying bitumen, which implements a compact layout of equipment, as well as a technology for preparing a product with any kind of modifiers and raw materials while reducing the duration of the process and reducing energy costs.

The technical problem is resolved by the fact that the installation for modifying bitumen includes a horizontally oriented reactor with a modifier loading unit, equipped with mixers, a heat heater, process pipes with shutoff valves, connected through a piping system with a pump unit endowed with a flow recirculation function. The agitators are installed with a vertical arrangement of shafts, spaced apart in the longitudinal direction of the reactor and are screw and milling mixers, the shaft and the working body of the screw mixer, enclosed in the shell of the screw mixer open from below, is located above the heater, the shaft and the working body of the milling mixer, enclosed in an open bottom casing of the milling mixer, made with windows, is located in the container introduced into the cavity of the reactor and representing the container of the milling mixer, made with walls that have through holes. The reactor is equipped with an inlet channel for supplying said bituminous feed stream into the milling mixer tank, and the end of the inlet channel separated from this tank is installed in a window made in the casing wall of the helical mixer. The capacity of the milling mixer is installed so that through the modifier loading unit the loading of the modifier is carried out directly into this capacity when the bituminous raw mixture is heated to a predetermined temperature of 150-180 degrees.

According to preferred embodiments of the invention:

- each agitator is equipped with an engine with a power of 7.5 kW, 1500 rpm, while the blades of the helical agitator as a working body are installed in an amount of at least 4 with an angle of attack equal to 32-46 degrees;

- the reactor is equipped with a device for removing vapors and gases;

- the unit is equipped with a control cabinet with an instrumentation system, designed to control the temperature of the product in the reactor, equipped with bitumen mixture temperature sensors.

The essence of the invention is explained as follows.

The presence of mixers of various types, enclosed in an appropriate casing and installed spaced apart in the longitudinal direction relative to the horizontally oriented reactor, predetermines the possibility of the most uniform distribution of modifying additives in the organic binder with the exclusion of stagnation zones in the reactor cavity during the movement of the bitumen feed stream with a given temperature not exceeding 180 ° C

The mutual arrangement of the stirrers is dictated by the presence of heating elements in the lower part of the reactor, introduced from its end. Therefore, it is expedient to install a helical agitator above the area where the heater is located.

Equipping a screw mixer (MV) with a corresponding casing (hereinafter referred to as the casing MV), made in the form of a pipe section, leads to the capture of the bituminous feed stream from below into the cavity of the casing (pipe section). Therefore, by placing a screw mixer above the heater, during the operation of such a mixer, conditions are created for creating a raw material flow rising from the heater location zone.

Taking into account the mutual remoteness of the agitators and based on one of the functions of the milling agitator - raw material grinding - such an agitator and a loading device can be located as close as possible. This constructive technique makes it possible to immerse the working body of the milling mixer (MF), enclosed in a tubular casing (hereinafter referred to as the casing MF), into the cavity of the container, terminologically designated as the capacity of the milling mixer (hereinafter referred to as the capacity MF).

The presence of an inlet channel connecting the cavity of the MF casing and the cavity of the MF tank creates the prerequisites for the continuous exchange of the feed stream both in the MF tank and in the rest of the reactor cavity due to the presence of slots in the MF tank, which excludes the appearance of dead zones that adversely affect the process of modifying bituminous raw materials .

Equipping the MF with a casing made with two windows of maximum height, firstly, allows the input of the raw material flow coming from the channel into one window and the exit of the flow from the other (second) window into the MF tank, and secondly, it creates the possibility of grinding the modifier near the working body MF. So, two zones are created in the MF tank: the first "high-speed" zone corresponds to the cavity of the MF casing around the working body of the MF in the area of the casing windows, and the second "low-speed zone" corresponds to the cavity of the MF tank.

The execution of windows of the MF casing of maximum height based on the height of such a casing is a constructive necessity associated with ensuring the flow from the supply channel directly to the working body of the MF (into the "high-speed" zone), as well as ensuring the supply of the untwisted flow from the action of the MF into the "low-speed" a zone with further distribution of the flow through the slots in the walls of the MF tank.

The slits made in the walls of the MF vessel prevent the general untwisting of the feed stream (as it could be in the absence of such slits) from the action of the MF in this vessel and provides intensive mixing due to the formation of a plurality of flows exiting the reactor cavity from the corresponding slots, creating a constant pulsation.

So, the container and the MF, together with the loading device, are a pre-mixing unit of the raw material flow, in which the following processes take place:

- swelling of the polymer (for example, rubber crumb), which came from the boot device;

- grinding of the polymer from the action of MF;

- mixing of the feed stream from the action of the MF, which comes from the supply channel, with the involvement of crushed polymer particles in this stream;

- pulsation of the flow in the area of the slits of the MF container, which creates the effect of dispersion.

Moreover, the above processes occur in the reactor continuously and in interconnection without the ability to distinguish the boundaries of the beginning and end of each of these processes.

In the proposed installation, it is possible to use any modifier, since the pre-mixing unit ensures the swelling of the polymer, its grinding (cutting) and uniform dissolution in the volume of the raw mass (in the volume of the raw material flow).

It should be noted that the presence of the inlet channel contributes not only to the continuous exchange of the feed stream in the reactor vessel, as mentioned above, but also leads to an improvement in the heat transfer of the feed stream due to the transfer of the flow itself from the action of the MW, which rises along the SM casing from below from the heating zone upwards and is supplied through the channel directly into the MF tank, designed to grind the modifier in the bituminous feed stream, which has the maximum allowable temperature. So, in order to avoid deterioration of the bitumen properties and to keep the modifier in an unmelted state, the set temperature is limited to 180°C.

The horizontally oriented reactor vessel provides a more uniform distribution of flows when bitumen is mixed with components, reduces the load on the mixing means, thereby ensuring a longer life of the mixers, their maintenance and repair, and also reduces the weight load on the mixing devices, ensuring ease of maintenance of the mixers when their conservation, maintenance or repair.

The use of the flow recirculation circuit makes it possible to obtain the finished product by repeatedly moving the mixture through the reactor cavity while increasing the productivity of the finished product production due to the integration of the mixing processes occurring in one reactor vessel from the action of agitators and the renewal of flows due to the presence of a supply channel and slots in the MF vessel.

Thus, the presence of structural elements and connections between them determines the most uniform distribution of modifying additives due to the continuous mixing of the flows in the reactor cavity, namely: , in turn, several pulsating flows are fed into the reactor vessel. The pumping unit and the piping system of the plant also predetermine the continuity of the mixing process of the flows interacting in the cavity of one reactor.

Based on the foregoing, in the proposed installation for bitumen modification there is no need to use tanks external to the reactor that require additional heaters, and there is also no need to use pipelines that combine process tanks and complicate the flow system. Consequently, the creation of this installation is characterized by a decrease in material consumption along the way of reducing power consumption, releasing functional (technological) means and constructive connections between them. At the same time, the quality of the modifying mixture remains at a high level and corresponds to the specified characteristics and GOST R 52056-2003.

Focusing on the work of the MF, the moment of bringing it into action is the achievement of the temperature of the bituminous mixture, not exceeding 180°C, while the acceptable temperature range is 150-180°C.

The use of an oil cooler or a tubular electric heater as a heater is determined by the alternative connection of the unit to the appropriate heating systems.

The filter and ultrasonic mixer introduced into the recirculation circuit bring additional benefits when using the proposed installation. The presence of an ultrasonic mixer reduces the segregation of the polymeric bituminous binder, therefore, provides the possibility of its further transportation without mixing every 2 hours and storage for a long time of at least 30 days.

These and other features of the installation are explained with the help of drawings:

- figure 1 shows a General view of the installation for the modification of bitumen;

- figure 2 shows the installation reactor, top view.

The installation contains a horizontally oriented reactor 1 with a piping system 2 with technological nozzles, including those for supplying a plasticizer, and a pumping unit 3.

Reactor 1 is equipped with agitators:

- screw mixer 4 (MV 4), the shaft and the working body of which is placed in a casing 5 open from below, made in the form of a pipe segment;

- milling mixer 6 (MF 6), the shaft and the working body of which are also placed in an open casing 7, made in the form of a pipe section, in the walls of the casing 7 there are two windows 8 located opposite each other.

The installation uses two means for heating the bitumen feed stream: an oil reslate (not shown in the drawing) and a tubular electric heater 9. This constructive technique is associated with various options for connecting the proposed installation to the corresponding systems of enterprises for the production of asphalt concrete mixtures and bitumen farms.

Oil resifer and tubular electric heater 9 installed at the end of the reactor 1 using a flange connection (not indicated by position) and flange leads (not shown in the drawing).

MF 4 and MF 6 are removed from each other, while MF 4 in casing 5 is installed above the area of heaters, and MF 6 in casing 7 is immersed in container 11, made with walls having vertical slots 12.

The container 11, called the capacity of the milling mixer, and the casing 7 MB are connected by a horizontally oriented inlet channel 13. The entrance of the channel 13 through a window (not marked with a position) made in the wall of the casing 5 MB 4 communicates with the cavity of this casing 5; the outlet of the channel 13 also communicates with its cavity through the corresponding window (not indicated by the position) made in the wall of the container 11.

In the horizontal projection plane, the channel 13 is set at an angle relative to the longitudinal axis of the reactor 1, which is due to the swirling of the feed stream in the casing 5 MV 4 and, as a result, the entry of this stream into the tank 11 is characterized as tangential. Based on this circumstance, the inlet channel 13 is installed to the tank 11 at an angle, providing a tangential flow to maintain speed and heat transfer.

The reactor is equipped with a loading device 14 for supplying bulk materials and modifier. Boot device 14 with a gate valve (not shown in the drawing) is installed using a flange connection (not indicated by the position) and is located above the tank 11.

The power of agitators is calculated according to the methods set out in public reference books and textbooks, for example, in the Guiding regulatory document RD 26-01-90-85: Mechanical agitators, calculation method. - Input. from 01.01.1986. - L.: RTP LenNIIkhimmash, 1985. - 257 p.

The working body of the MW consists of blades (not marked with a position) mounted on the shaft at an angle of 32-46 degrees, selected based on ensuring the capture of the flow of the raw mixture coming from the bottom of the casing 5 and lifting the fluid flow along the casing. This constructive technique is not disclosed in detail in the description, since it is known from the prior art that the calculation of the angle of attack of the agitator blades to solve the set technical problems is carried out using publicly available sources of information, for example, the following publications:

- Ioffe I.L. Design of processes and devices of chemical technology. - L.: Chemistry, 1991;

- Kasatkin A.G. Basic processes and apparatuses of chemical technology. - 9th ed., Rev. - M.: Chemistry, 1973.

The proposed installation introduced an ultrasonic mixer 15 (UZS) 15 as an additional tool to the fixed assets that provide the process of grinding and mixing modifying additives in the reactor 1.

USS 15 is designed to further reduce the modifier particles coming from the reactor 1 to an identical size, which completely coincides with the dissolved mass, which contributes to the uniform distribution of such particles in the raw material (bitumen) and the homogeneity of the bitumen-based mass.

Thus, the use of a bitumen modification plant in a configuration with an ultrasonic mixer, due to sequential processes for the production of polymer-bitumen binder, leads to homogenization (reduction in the degree of heterogeneity) and dispersion of the raw material flow, which is a prerequisite for creating a product capable of long-term storage.

The ultrasonic mixer disclosed in the utility model patent RU 25427 (published on 10.10.2002) is known from the prior art. The specified mixer, intended for obtaining emulsions, includes a system of resonant plates, each of which has its own resonant frequency.

In order to avoid clogging of the USS 15, the proposed installation uses a centrifugal filter 16 with a filter element and a grate.

The installation also contains a device for removing vapors and gases (not shown) when the modifier is supplied to the reactor through the loading device 14.

The proposed installation is equipped with a control cabinet 17 with an instrumentation system, including a temperature control system in the reactor.

The equipment included in the installation is installed on a frame structure 18 with the possibility of transportation, subject to the required dimensions and installation on the site of the enterprise.

The operation of the installation is carried out as follows.

Heated bitumen is poured into the reactor 1 to a temperature of 120 degrees, then the electric heater 9 is turned on and at the same time a plasticizer is introduced through the corresponding pipe through the pump unit 3, designed to improve the connection of rubber (modifier) with bitumen, as well as its dissolution and swelling in the bitumen medium.

Turns on MB 4; when bitumen is mixed with a plasticizer in the reactor 1, it forms a stream of bituminous raw materials, which rises along the casing 5 and is poured (fed) through the channel 13 into the container 11.

At the same time, the temperature of the bituminous raw material in the reactor 1 increases and, upon reaching 150-180 degrees, MF 6 is turned on.

After turning on the MF 6 through the device 14, the SBS (styrene-butadiene-styrene) modifier is supplied to the container 11. When the temperature of the raw mixture reaches 180 degrees, the device for removing vapors and gases is turned on to remove hot and harmful vapors when this modifier is added.

Simultaneously with the start of operation of the MF 6, the flow of raw mixture from the area above the heater 9 is drawn into the casing 5 by means of the rotating blades of the MF 4 and is fed through the supply channel 13 simultaneously into the cavity of the tank 11 and into the cavity of the casing 7 of the MF 6 through the window 8, while the second window 8 serves as an outlet for the flow created by the work of the MF 6.

Thus, the supply channel 13 creates an overflow of the modified bituminous liquid inside the reactor 1 for a more complete solubility of the modifier, mixing and increasing the feed stream created by the MW 4.

In addition, the operation of the pump unit 3 and the piping system creates a circulation flow of bituminous raw materials, continuously mixed directly in the reactor vessel 1, as described above. Further along the pipeline connecting the reactor 1 with the pumping station 3, the flow again enters the reactor.

The process of modifying bitumen to obtain a product in the form of a polymer-bitumen binder begins from the moment MF 6 is put into operation. Thus, being continuously updated during circulation and mixing, the bitumen stream becomes a product within 4 hours.

It should be noted that the SBS modifier is fed into the loading device 14 almost continuously (one portion follows the other) for 3 hours.

With a reactor capacity of 15 m ³ it is possible to prepare a product with a SBS content of 1.5% to 21%.

If UZS 15 is included in the installation, it is possible to obtain a polymer-bitumen binder with a high degree of dispersion.This circumstance leads to the ability to store the finished product without mixing for up to 30 days, which is a significant factor when it is necessary to transport the product over long distances.

With the help of control cabinet 17, the stages of a single technological process for creating a polymer-bitumen binder are controlled, including the following processes:

- control of bulk products loading, including SBS modifier;

- inclusion of a screw stirrer;

- heating to a temperature not exceeding 180 degrees;

- inclusion of the device of an output of vapors and gases;

- turning on the milling mixer;

- inclusion of circulation within 2 hours.

The readiness of the product is evaluated on the basis of the analysis of the samples taken: when the product is ready, the polymer-bitumen binder is drained, otherwise the circulation process continues for an hour.

Based on the foregoing, it follows that the proposed installation is characterized by:

- reducing the preparation time of the product to 4 hours with an increase in the maximum degree of dissolution of the modifier and the homogeneity of the finished product;

- the possibility of transportation and storage of the product for a long time;

- the possibility of producing a highly concentrated product with subsequent mixing in the working capacity of the plant;

- versatility in terms of the use of various types of raw materials in the form of modifiers due to the presence of a pre-mixing unit;

- reduction of material consumption along the way of reducing the equipment included in the installation, including the one requiring heating costs;

- simplification of the design when introducing new tools with a simple design (supply channel, slotted container, tubular casing of each mixer);

- reduction of energy intensity due to the use of a single reactor heater while ensuring improved heat transfer between flows in the reactor cavity.
