Abstract

1. INSTALLATION FOR CLEANING OIL-CONTAINING WATER, including a filter with a granular load, a pipeline for supplying raw water connected to it, a pipeline with an automatic valve for draining flushed water, a pipeline for supplying washing water with a non-return valve and a pipe connecting the latter pipeline and an automatic the valve, distinguished by the fact that, in order to improve the quality of the filter penetration, it is equipped with a sealed chamber located on the pipeline section for the supply of flush water between the non return valve pan and pipe, while the chamber has a nozzle with a non-return valve for supplying air and is connected to the pipeline by means of a feed nozzle with a locking element installed in the lower part of the chamber and an outlet nozzle located in its upper part. 2. Installation according to claim 1, which means that the locking element is designed in the form of a float.

Description

00 Izofethenia refers to the structures. for the treatment of industrial or domestic wastewater, for example, for the treatment of oily water that accumulates under the slabs of machine-boiler vessels. A known device for treating oil-containing water, including a filter with a granular charge, with supply and discharge pipes, the pipe for supplying flush water having a non-eelectric valve connected to the filter pipeline for supplying the original Water, a pipeline with an automatic valve. “For draining flushing water, a flush water supply line and a pipe, soy: The last last pipe and automatic valve. In this setup, the filter is automatically rinsed each time the cleaning system is turned on and each time the oil products from the vacuum separator are drained. Washing is carried out with a stream of washing water, loosening and re-stretching the loading layers and washing out of it. The main drawback of this installation is the impossibility of ensuring intensive mixing of the loading layers when washing the filter, which reduces the quality of washing of the filter loading. The aim of the invention is to improve the quality of filter flushing. The goal is achieved by the fact that a plant for oily-containing water sludge, including a filter with a granular load, a pipeline for supplying raw water connected to it, a pipeline with an automatic valve for draining the wash water, a pipeline for supplying flush water with a non-return valve and a pipe, connecting the last pipeline and automatic valve, is equipped with a pressure chamber located on the pipeline section for supplying the flowing water between the non-return valve and the pipe, while the chamber has logging with a non-return valve for feeding voeduha and connected to the supply conduit through the nozzle with a locking element mounted in the bottom of the chamber and discharging pipe disposed in the upper portion thereof. It is advisable to perform the locking element in the form of a float. The drawing shows the scheme of the proposed installation. The installation contains a pumping body 1 with a receiving pipe 2, lo e, a filter 3 with a granular load, equipped with a pipeline for draining water 4 with an automatic valve 5,. . the flush water supply pipe e with a non-return valve 7 and a solenoid valve, connected by a pipe 8 with a receiving pipeline 2 and an automatic valve 5. The pipeline for supplying flush water 6 in the section between the pipe 8 and the non-return valve 7 is equipped with a chamber 9 equipped with an inlet connection Yus in the lower part an automatic shut-off element made in the form of a float 11, for example, a float, an air inlet nozzle 12 with a non-return valve 13, and in the upper part - an outlet nozzle 14. Transfer body 1 tube 15 co A filter with filter 3, filter 3 is equipped with a pipe 16 for discharging purified water. The installation works as follows. The oil holding water through the pipeline 2 and the pipe 15 is transferred by the pumping body 1 to the filter 3. The water in the chamber 9, due to the vacuum created by the pumping body 1, flows through the pipe 8 also into the receiving pipe 2. At the same time, non-return valve 13 and the nozzle 12 of the air inlet to the chamber 9 enters the air from the atmosphere. Non-return valve 7 prevents water from filter 3 from entering chamber 9. After chamber 9 is emptied, float 11 closes the inlet 10, excluding the flow of air into the receiving pipe 2. Purified water drains overboard through pipe 16. system operation and at specified intervals. This opens the solenoid valve 17, the flushing water from the pipeline 6 enters the chamber 9 and forces the air out of it into the filter 3, which extracts bubbling, intensive loosening and mixing of the loading layers, as a result of which the contaminants are separated. After filling the chamber 9, water enters the filter and washes the already loosened load, which increases the effectiveness of the washing. After the end of the rinsing of the filter 3 (after 3-4 minutes), the pumping valve 1 is turned on, the solenoid valve
