InUS2003178048 is disclosed a cleaning equipment for cleaning a moving surface particularly in a paper machine includes a washing head with a chamber in it opening onto the surface to be cleaned and nozzle elements arranged inside the chamber. The cleaning equipment also includes vacuum means and removal means. - In
WO9513422 - In
US 6227460 B1 , which is considered as the closest state of the art is disclosed a system in accordance with the preamble of claim 1. - However, the present development offers a series of advantages of an economic, technical and operational nature, and also makes it possible to have greater performance from the equipment for the proposed purpose.
- The aforementioned problems are solved by a system in accordance with claim 1.
- The matter will become perfectly understood in the following description:
-
FIGURE 1 - schematic view of the water feed system of the system, and its circulation; -
FIGURE 2 - schematic view of the water and steam feed lines, with the other intermediate devices; -
FIGURE 3 - schematic view of the water and steam lines and their interconnection with the chemical product containers, connected to the dosage pump, to the thermal injector pump or heat exchanger with, high-pressure pump, and to the showers or injector devices for feeding the final solution into the system; -
FIGURE 4 - schematic view of the water, steam and chemical product lines, going through the thermal injector pumps or heat exchangers with high-pressure pumps, with interconnection with the protection chambers for the structure, with an external command panel and external showers with internal telescopic fit guides, or other injector devices; -
FIGURE 5 - schematic view of the internal layout of the showers with internal telescopic fit guides which allow unblocking of the injector nozzles with halting the operation of the system; -
FIGURE 6 - schematic view of the combination, with detailing of the distribution network and lead lines for water, steam and chemical products or enzymes; -
FIGURE 7 - schematic view of the system in accordance with the invention -
FIGURE 8 - schematic view of an embodiment of the invention, with the provision (by way of example) of three showers and an injector and spraying device, showing all the equipment that it is composed of, which can be utilized in parts or with more branches, connected in parallel, according to the needs. - As can be seen from the said illustrations, the system consists of a principal water feed pipe (1) from which a lead line (2) for fresh water goes out to the set, passing through filters (3) and stored in the tank (4), and is taken through the pressure-raising and pressure maintenance pump (5). There is also provision for a principal pipe (6) for steam feed, which is led through the line (T) to the system, passing through a device for extracting condensate (8) and then through the steam filter (9). From the containers for continuous chemical product or enzymes (10) and shock containers (11), the feed pipes (12) for these go out to the system. In this, the first line goes through the dosing pump (13) and flow measuring device (14), and the two pipes (12) are led to the protection chamber, with a support structure and external indicator panel (16). Inside this, the thermal injector pumps or heat exchangers with a high-pressure pump (15) are housed, with outputs in pipelines leading the pressurized chemical solution (17) to the showers with internal telescopic fit guides (18), ejector devices (22) or spraying devices (23), for spraying out the cleaning product. There is provision for a mixing tank and lowering of pressure and temperature (19), and the tubular showers (18) are provided with sliding internal cylinders (20), in which the spraying nozzles are attached (21).
- Thus, the system has provision for optional use of adaptations of ejector devices (22) or spraying devices (23), together with the showers (18), which are all destined for the outlet from the pipelines (17) that lead the pressurized chemical solution. These may be destined, respectively, for cleaning the felts and screens in paper and cellulose machines, other parts of these machines or, additionally, other equipment.
- It can thus be observed, as listed in the following, that the modifications introduced enable the existence of a series of advantages and improvements in relation to the previous system, which ;can be identified through the following characteristics:
- In the water feed part, the fresh water filters (3), the tank for storing the fresh water (4) and the pump for raising and maintaining the pressure of the fresh water (5) have been incorporated.
- These devices have the purpose of reducing the quantity of water utilized in the system, improving the water quality and stabilizing the pressure of the water admitted into the thermal pumps or heat exchangers with high-pressure pumps.
- The quantity of water utilized in the system can be reduced as the quality of the water is improved, since this provides a reduction in the quantity of contaminant and also reduces the size of these elements, and thus the ejector nozzles for the chemical solution in the showers can have smaller diameters and consequently this gives rise to lower consumption of the sprayed chemical solution, and therefore lower water consumption.
- In the steam feed, a steam filter (9) and a device (8) for condensate extraction (for example, a purger or other manual device) have been coupled to the previously known equipment. Meanwhile, in the part for feeding chemical products and/ or enzymes, the following have been incorporated into the existing system:
- The storage container for chemical products (11), which has become present in greater numbers, for each high-pressure thermal injector pump or heat exchanger with high-pressure pump, and a storage container is utilized for the continuous chemical product and/or enzymes (10) and another for the shock product (11).
- The dosing pump (13), which has become utilized only for continuously dosing the solution. It can, in certain cases, be replaced by a device for measuring the chemical products, which are directly sucked in by the thermal pump. The device (14) provided for in the following may be a measuring glass, rotameter or any type of flow measuring device (electromagnetic or other).
- In the dosing of chemical product for shock, the utilization of the dosing pump can be done away with when the thermal injector pump is utilized, since this sucks in the chemical product directly. However, when a heat exchanger and high-pressure pump is utilized, the dosing pump (13) needs to be used for the chemical product.
- In the part of the system responsible for raising the temperature, raising the pressure and preparing the chemical solution and/ or enzymes (15), the following devices have been incorporated:
- Protection chamber (16) for the thermal injector pump(s), which have a safety purpose regarding thermal protection for the set, and also the incorporation of an external indicator panel for water, steam and chemical solution pressure and also for the temperature of the mixture.
- Two or more thermal injector pumps (15) or heat exchangers, together with the high-pressure pumps, work in parallel, thereby allowing the fabrics of the paper or cellulose machines to be treated individually and in a personalized manner. "
- With this latter innovation, the system can start to attend to several fabrics simultaneously, thus allowing the control conditions for temperature, pressure, outflow of the solution and dosing of chemical products and/ or enzymes to be done differently for each of them.
- The original system did not allow different fabrics for the same application to have individualized treatment, since a single piece of equipment would attend to all of them simultaneously.
- With the incorporation of these items, users of the system will have a large number of benefits in addition to those cited earlier, such as:
- Reduction in the consumption of fresh water; Reduction in steam consumption;
- Reduction in the consumption of chemical products, since the fabrics are treated individually, with the utilization of only what is necessary for each one and not all together;
- Better performance from the paper and cellulose machines, since each fabric starts to have its own treatment, as a function of its characteristics and lifespan
- The chamber (16) offers a structure inside it for assembling the thermal injector pumps or heat exchangers, together with high-pressure pumps, which ensures protection of the equipment and. users.
- In the showers of telescopic type for the application of chemical solutions in the paper and cellulose machines.
- When the paper or cellulose machines are working, it may happen that one or more shower nozzles become blocked. Such blockages can occur from inside to outside, or from outside to inside, according to the particular environmental conditions of each section if each paper and cellulose machine.
- When blockages occur in any of the ejector nozzles, which may harm the quality of the product obtained, either the operation of the paper or cellulose machine is halted for cleaning the nozzles, or the operation is allowed to continue until it is possible to stop the machine for preventive or corrective maintenance.
- In both cases, the operation is impaired, such that in the first case there is the consequence of lost production and in the second case the treatment of the fabrics in the machines is prejudiced, with consequent problems and alterations in the moisture profile and the vacuum in the suction boxes, thereby leading to greater energy consumption, etc, with obvious losses of quality in the paper or cellulose produced.
- To resolve this type of problem, the shower devices with internal telescopic fit guides have been incorporated into the present development. These showers are constructed with a double body, i.e. an external one that is attached to the structure of the machine that will be treated and an independent internal one in which the spray nozzles and respective guides for removal and insertion are located.
- When necessary, the internal part of the shower is removed for corrective maintenance (for example cleaning of the nozzles, joints, etc) by the personnel in charge of the paper or cellulose machines while in operation, so that their production is not interrupted, and such maintenance can be carried out by this personnel, without the need for specialized labor.
- Devices have been, incorporated for reducing the temperature and pressure of the solution utilized and for simultaneous utilization of other chemical products and/or enzymes (with or without mixing), for application to certain parts of the paper and cellulose machines, which will be treated in different manners. These devices (kits) are placed in strategic intermediate positions in the system, and each of them is composed of parts shown in the diagram of the set, and the temperatures are reduced from the range of 75°to 90°Cto 40°to 60°C and the pressures from 7 to 25 bar to 1 to 6 bar.
- The system based on the equipment now developed aims to eliminate a series of technical problems at present faced by paper manufacturers, with the objective of increasing the productivity of the machines and improving the quality of the final product, without any harm to the environment.
- The integrated and optimized application of the three components (fresh water, chemical products and pressure and heat) result in better performance for the system, for continuous treatment of the fabrics of paper and cellulose machines, thereby ensuring the operational benefits of: stability in the operation of the machine and a notable reduction in the number of breakages in the processed sheets; reduction in the time lost through interruptions in paper production for cleaning the fabrics, rollers, boxes, etc; better quality of the sheets obtained, with regard to their formation, uniformity and resistance.
