Description

This invention relates to devices for the purification of industrial condensates and other industrial waste waters polluted with oils and petroleum products. Closest to the proposed by the technical essence and the achieved result is a plant for cleaning industrial condensates from oils, including a pressure filter with filtering material bukker for receiving contaminated filter material, pressing equipment for extraction and a container for removing the regenerated material connected to the filter hydrotransport piping 1. A known installation is highly efficient and efficient only when cleaning industrial condensates from low-viscosity oils and not products is envisaged. When cleaning condensate or wastewater containing highly viscous petroleum products and suspended solids, the upper layer of the filter charge is quickly clogged. Regeneration of the above material by pressing even when hot water is supplied is practically impracticable. All this significantly reduces the efficiency of the known installation. The purpose of the invention is to increase the efficiency of the installation when cleaning from high-viscosity petroleum products. This goal is achieved by the fact that in a plant for cleaning industrial condensates from oils containing a pressure filter with filter material, a hopper for receiving contaminated filter material, a pressing device and a tank for collecting regenerated material connected to the filter by a hydraulic conveying pipeline, 4 and 1-Tr performed in the form of a horizontal cylinder divided in length into sections, the density of the filtering material in which is increased, and the pore size decreases from section to section When this installation is provided with labor & a steam supply wire connected to a hopper for receiving contaminated material. The proposed constructive implementation of the installation allows to increase the temperature in the zone of regenerating filter material, which increases the fluidity of viscous contaminants and facilitates the subsequent spin of the filter material, ensuring high quality regeneration. In addition, ensuring the variable porosity of the load during the movement of the fluid ensures maximum use of the entire volume of the filter load and, therefore, increases the oil capacity of the filter. The horizontal arrangement of the filter ensures the removal of the filtering material during its hydrotransport without the use of special guide partitions, whose function in this case is the internal cylindrical surface of the filter section. Combining the filter sections with the receiving bin and the tank for collecting the regenerated material by the hydrotransport pipeline allows more often to regenerate the most polluted filter charge located in the first section rather than the entire volume. As a result, the efficiency of the facilities increases substantially. FIG. 1 shows the proposed installation, a general view; in fig. 2 shows section A-A in FIG. , 1 (filter, cross section). The installation includes a pipeline 1 for supplying contaminated condensate, a tank 2 for settling it, a pipeline 3 connecting the tank 2 with a pressure filter 4 made in the form of a horizontally arranged cylinder divided along the length of section 5-7 with perforated partitions filled with polyurethane foam chips with increasing density as the fluid moves, and a regeneration unit associated with sections 5-7 of filter 4 by means of a pneumatic or transport system. The regeneration unit consists of a hopper 8 for receiving contaminated filtering material, squeezing device 9 with metering valves 10 and a tank 11 for receiving the pressed filter loading. The metering valves 10 ensure the tightness of the working area of the squeezing device 9 and connect it to the hopper 8 in the upper part and the tank 11 in the lower part. The installation includes a pipeline 12 for withdrawing the purified liquid, as well as a pipeline 13 for supplying the transport water. The sections of the filter 4 are connected to the receiving bin 8 by the pipeline 14 and with the tank 11 by the pipeline 15. The pipeline 16 serves to supply steam to the hopper 8 and to the pressing device 9 (steam source e is shown) and the pipe 17 to return water from the regeneration unit to the tank 2. Moreover, the installation is equipped with a pump 18. Pipelines 3, 12, 13, 14, 15 are equipped with valves 19-41. The installation works in the following way. A drop containing up to 100 mg / l of non-product having a viscosity of about 000 cSt and a suspension enters through conduit 1 into tank 2, where it is settled for 1.5-2 hours, and then through conduit 3 with open valve 19 is fed into section 5 having a density of filtering material 50 kg / m. Then, through the opening of the valve 30, with the valves 33 and 29 closed, the liquid enters section 6, having a filter material density of 65 kg / m, and then with the valve 35 closed and the open valve 28 closed, section 7 with a filtering material density of 80 kg / m. The purified fluid is removed from filter 4 through conduit 12 with gate valves 37 and 31 open. When the concentration and contamination in the purified fluid is increased or the maximum loss of pressure is reached, the filter charge is subjected to regeneration. To do this, the contaminated filter media under the pressure of water created by the pump 18 supplied through conduit 13 with open valves 22, 32 and 38, for example, section 5, is expelled from the latter and passed through conduit J4 into the hopper 8, after which valves 22 and 38 are closed. In the bunker 8, the filtering material is freed from the water discharged through the conduit 17 to the tank 2. Then to the hopper 8 and to the wringer 9, the steam 17 is supplied to the steam and the temperature in the hopper zone rises to 80 ° C, which reduces the viscosity of the fuel oil to 65 cSt and below, which increases the fluidity of viscous petroleum products that fill the pores of the filter material. The steam supply does not stop until the regeneration is completed. After 5-10 minutes, the shutter 10 opens and the filtering material enters the squeezing device 9. The highly viscous contaminants in the load and the steam treatment in the hopper 8 do not lose their increased fluidity in the squeezing device area. 9. This contributes to the efficient spin and high-quality regeneration of the filtering material. Through the bottom flap 10, the regenerated material enters the tank by the flow of transporting water, the transfer from the tank 2 by the pump 18 through the open valves 41 and 39 on the pipe 15, the regenerated filter material is directed to the section from which it was removed with the corresponding valve open (32, 34 or 36). Thus, the loading density in each section after regeneration is not disturbed. The results of the comparison of the performance of the known and proposed installations are given in the table. As can be seen from the table, the cleaning efficiency of industrial condensate with the same filtering modes and the size of the filter loading on the proposed unit is higher than on the known one. The duration of the filter cycle is more than doubled. In this case, the regeneration of the filtering material contaminated with fuel oil in a known installation is so ineffective that after 1-2 filter cycles, its replacement is required. In the proposed facility, despite the long filter cycle duration and large loading capacity, the filter material is used for practically the entire standard service life of polyurethane, which is 1-1.5 g. The use of the entire filter loading volume (100%), which is achieved with a horizontal arrangement filter, allows you to purify more wastewater (i.e., increase the duration of the filter cycle) than when using a fraction of the volume (80%) fr. Thus, the efficiency of the installation is significantly increased with the horizontal position of the filter. In addition, in the proposed design, the regeneration of the filtering material of each section is performed sequentially, and the material of one section is not mixed with the material of the other section. As a result, the loading density in each section is not affected.
