Description

This device belongs to the devices for cleaning wastewater from microbiological contamination of various enterprises for the safe disposal of waste without the need for prior collection, removal and disposal at specialized landfills. The device can also be used to prepare liquids for further cycles of various industries.

Known installation for purification and disinfection of water (RU 2304561 C2), which is a process chain consisting of a hydrocyclone, a receipt reactor, a cyclone, electrodes and a filter.

The disadvantage of such a device is the overall complexity due to the presence of a large number of nodes in the circuit. This installation is calculated for specific productions and is limited in regulation due to the initially specified geometric dependencies.

The objective of the proposed utility model is to create a universal device for cleaning wastewater from microbiological contamination of various enterprises in order to safely dispose of waste without the need for prior collection, removal and disposal at specialized landfills.

The task is solved by a plasma-chemical cleaning device containing a housing in which a transformer is located to ensure the formation of current pulses with a voltage of more than 10 kV, a discharge chamber in the form of a quartz tube with built-in ring electrodes repeating its contours at the edges, a hydrodynamic emitter and connecting elements. The shape of the electrodes provides a more uniform distribution of the discharge in the plane of the section of the discharge chamber compared to a point input, and also has a simpler installation. The hydrodynamic emitter is located in the inlet, and fastening connections are additionally installed on the device body.

Fasteners at the inlet to the reactor (tube) and the outlet from it are made in the form of branch pipes with a radial seal and thread. These connections are located at the inlet and outlet of the housing. Fasteners on the wiring of the high-voltage part are made in the form of a socket with a thread at the inlet and a connector at the outlet with a clamping nut.

The proposed device for plasma-chemical purification from microbiological contaminants is shown schematically in Fig. 1 where:

1 - body

2 - transformer

3-bit chamber in the form of a quartz tube

4 - power socket

5 - hydrodynamic emitter

6 - fastening connection

7 - electrodes in the form of rings

The device works as follows. The treated liquid enters the working cavities of the discharge chamber (3) in the form of a turbulent flow created by a hydrodynamic emitter (5), resulting in a favorable environment for the process. Current pulses are fed through the power socket (4), which are converted into high-voltage pulses by a transformer (1) and transmitted to the ring electrodes at the edges of the discharge chamber (7). Plasma is formed in a liquid flow. During operation, free radicals, ozone and partially hydrogen peroxide are released. Thermal exposure, ultraviolet radiation and exposure to electric fields additionally inhibits microbiological activity.

The device also has the additional ability, if necessary, to expand the working area by increasing the number of processing modules, which allows you to repeatedly increase the time of exposure to destruction mechanisms and clean up effluents with much higher initial concentrations of pollutants. For these purposes, the device is additionally equipped with a fastening connection (6), the hydrodynamic emitter is detached, allowing a similar device to be connected through the released fastening, and current pulses are transmitted through the output on the back of the power socket (on the back of the case).

Blocking allows you to adjust the processing time in accordance with the required tasks and rebuild the scheme in a short time without significant capital and time costs. The operation of the device at different formed lengths is regulated only by the input pressure and the power of the supplied current pulses without the need for geometric changes in the design. The fastening connection at the inlet to the discharge chamber makes it possible to seal the docking point, and the fastening connection at the outlet of the discharge chamber makes it possible to install a liquid flow outlet or dock with subsequent modules. The rigidly fixed high-voltage part inside the housing allows the transmission of high-frequency current pulses without the need for additional cable connections, connecting the overall system to a single power source.

Thus, the proposed utility model has a fairly simple design, but at the same time allows you to clean the effluents of various enterprises for the safe disposal of waste without the need for prior collection, removal and disposal at specialized landfills. The device can also be used to prepare liquids for further production cycles.
