Description

The invention relates to the treatment and disinfection of drinking and wastewater by electrical methods and can be used in various sectors of the economy, in particular at enterprises of domestic and special purposes, as well as in various technological processes that use the energy of electric discharges.

The purpose of the invention is the reduction of 10 energy costs for disinfection of water.

In FIG. 1 shows an installation for disinfecting water; in Fig. · 2 · timing diagrams of the device; in FIG. 3 is an equivalent circuit.

Installation for disinfecting water (Fig. 1) consists of a constant high voltage source, in series with which are connected Inductive elements 2, generators 3 of high-voltage pulses. In series with the generators 3, forming arrester 4 and process chambers 5 are connected, in which high-voltage 6 and grounded-25 polarity of the applied pulse 7 electrodes are installed. High-voltage electrodes 6 of the technological chambers 5 are interconnected by capacitors 8.

Installation for disinfecting water by electric discharges works as follows.

From the high-voltage source 1 of constant voltage, all generators of 3 pulses are simultaneously charged through inductive elements 2. When the voltage on the pulse generators is sufficient to breakdown the forming arresters 4, they are almost simultaneously broken down and the voltage is applied to the electrode systems of technological chambers 5, in which by the action of energy released in the interelectrode spaces along the channel

INSTALLATION FOR WATER DISINFECTION BY ELECTRIC DISCHARGE, containing a power source connected through inductive elements to pulse generators connected to technological chambers for water treatment by means of a block of forming arresters with electrodes, which is necessary in order to reduce specific energy consumption for disinfection of water, it is equipped with capacitors installed in the connection line of the electrodes of the forming arresters from the side of the technological chambers of the discharge discharges, water is disinfected . Almost simultaneous breakdown of all arresters 4 occurs as a result of the fact that the arresters are tuned to one operating voltage, and the first operation of any spark gap is of a statistical nature (the occurrence of an effective electron ”), so the first breakdown is observed in any of. arresters. As a result of this, a voltage pulse is applied to the capacitance 8 connecting the high-voltage electrodes 6 of the process chambers 5 (Fig. 2). In the equivalent circuit shown in FIG. 3, C ₈ corresponds to a capacitance 8 (Fig. 1), R is the resistance of the water column in the process chamber 5. After applying the voltage, it will be redistributed in the serial circuit and R and, as a result, on the resistance R at time t (Fig. 2) there will be a peak voltage of the same polarity as I. After the breakdown of the interelectrode gap in the process chamber in which the first spark gap was triggered, the voltage Ts _g (Fig. 2) corresponds to the time tg, and there is a peak of reverse polarity voltage on the resistance R. This voltage is added to the voltage on the spark gap 4 and the breakdown of the latter occurs under the action of overvoltage on it, and since all the spark gap 4 are interconnected by capacitors 8 (Fig. 1), they work simultaneously. In this case, the variation in the operation of all arresters 4 relative to the operation of the first of them is determined by the time the discharge forms in the technological device, which usually ranges from fractions of a microsecond to several microseconds.
