Abstract

CLEANING SYSTEM FOR OIL-CONTAINING WATERS, including oil-containing water collectors, a pumping body, a separator, a suction pipe connected to it with a pressure switch installed on it and receiving processes located in oily water collections that, in order to simplify the operation of the system, it is equipped with a shell open on top of the receiving processes, the bottom of which is located at the level of the holes made in the walls of the receiving processes.

The invention relates to systems for purifying oily water, mainly ship water, and can also be used in other facilities where it is necessary to purify oily water.

Closest to the invention is an oily water purification system comprising oily water collectors, a pumping body, a separator, a suction pipe connected to it with a pressure switch installed on it and receiving processes 1.

This system is characterized by complexity due to the presence of a float device, which requires maintenance costs, and lack of reliability due to the possibility of the “freeze-up of the float and suction of practically” pure oil in case of its loose fit to the seat.

The purpose of the invention is to simplify the operation of the system.

The goal is achieved by the fact that the cleaning system of non-petroleum-containing waters, including oily water collectors, a pumping body, a separator, a suction pipe connected to it with a pressure switch installed on it and receiving processes located in oily water collectors, is open from above shell, the bottom of which is located at the level of the holes made in the walls of the receiving processes.

FIG. 1 shows the proposed system of purification of oily water; in fig. 2 - receiving process with shell; in fig. 3 - the same, if the supply of oily water is cut off.

The purification system for oily hair consists of a pipeline 1 for discharging purified water, a pumping body 2, a separator 3, a pressure switch 4 installed on the suction pipe 5, receiving processes 6 located in collectors 7 of oily water, shell 8 with an open upper end and bottom 9 and holes 10, located in the walls of the reception processes.

The operation of the proposed system is as follows.

By the pumping body 2, the oily water from the collections 7 through the shell 8 and the processes b through pipeline 5 is sucked into the separator 3, where it is cleaned and discharged through pipeline 1.

When the level of oily water in collections 7 of the upper end of both gulls 8 is reached, the oily water below the level of the bottom 9 of the shell 8 is prevented from leaking air through the holes 10 and changing the pressure.1 in the pipeline 5. As a result, the pressure switch 4 generates a signal for switching off 5 of the pumper organ 2. This eliminates the possibility of the ingress of 3 layers of practically “pure oil” resulting from the sludge of oil-containing water in collections 7 into the separator

The application of the present invention simplifies the cleaning system, reduces the cost of its maintenance and increases the reliability of the system.
