Liquid Purification Unit

The utility model relates to the field of industrial water treatment. In addition, the installation can be used for clarification (purification) of low-viscosity liquids, for example, such as gasoline, kerosene, solvents.

Known filtering unit Yu.M. Kostrikin and others. Water treatment and water regime of power facilities of low and medium pressure. Directory. M., Energoatomizdat, 1990, p. 19-21, 226-227, Fig. Clause 8., Containing a container with an upper distributor (inlet) connected to the filtered fluid supply pipe and a lower distributor connected to the clarified liquid discharge pipe (filtrate). The filter charge is located at the bottom of the tank. The installation is flushed through the lower distributor, while the slurry flushing fluid is discharged through the upper distributor.

The filtering process in the installation is carried out from top to bottom, and as the layer of sludge on the surface of the filtering load increases and compacts, its throughput (productivity) quickly decreases. In addition, up to 10% of the already filtered liquid is spent on flushing the installation, which further reduces its performance.

The technical challenge facing the utility model is to create a plant with higher performance and not requiring a large flow rate for flushing.

To solve the technical problem in the installation, designed to clean the liquid from suspended solids, containing a container with an inlet for supplying the cleaned liquid and outlets for the output of the purified liquid and filtered sludge and placed in the tank

filter loading, the latter is located in the upper part of the container above the inlet for supplying the cleaned liquid, while the outlet for the purified liquid is located higher than the filter loading, and the outlet for the filtered sludge is located in the lower part of the container.

The drawing shows a diagram of the installation for cleaning liquids from suspended solids.

Installation for cleaning liquid from suspended solids contains a container 1 with input 2 for supplying the cleaned liquid to the middle zone of the tank. In the upper part of the container above the inlet 2 there is a filter load 3, for which, for example, quartz sand can be used for water treatment. In addition, the tank is equipped with an outlet 4 located above the filter load for outputting the purified liquid and outlet 5 for outputting the filtered sludge located in the lower part of the vessel below the load 3 and input 2.

To prevent subsidence and shedding, the load 3 from the bottom is limited by a grid 6, on which a filter cloth is laid, for example, of a non-woven synthetic material.

The cleaned liquid at the inlet 2 enters the tank 1, rises up through the filter load 3 and is discharged through the outlet 4.

As the filtered sludge layer (cake) increases and gets heavier, on the lower surface of the load (on the restrictive mesh 6 and the filter cloth), it spontaneously breaks off and settles in the lower part of the tank into the sludge collection zone. During shutdowns or reduced installation performance, sludge from the liquid located in the middle zone of the tank under the load also settles in the collection zone. The larger this area, the longer the inter-treatment period.

The installation is flushed by briefly opening branch 5 to discharge sludge into the drainage.
