Description

The invention relates to the field of water disinfection, in particular, can be used to supply chlorine gas to the treated water.

A known chlorinator (see, for example, passport for chlorinator LONII-100K, serial number 1951, chl. 00.000. PS. Repair experimental plant for public utilities. - Kremenchug, 1979), containing a filter, a membrane chamber, a pressure reducing valve, high and low pressure, rotameter, mixer, flow valve, ejector, inlet pipe and shut-off valve for supplying chlorine gas to the mixer, as well as a metering tank with a float valve and overflow pipe.

A disadvantage of the known chlorinator is that the ejector absorbs gaseous chlorine from the mixer together with the water in it, which, due to the high concentration of chlorine, leads to the formation of hypochlorous acid, which destructively affects the materials of construction that come into contact with it and thereby shorten the life of the product.

The closest in technical essence and the achieved result is a device for dosing chlorine gas (RF patent 1692627, 01 P 3/04), containing a filter, control and shut-off valves, rotameter, ejector, water line connected to the gas supply line of the mixer, which contains a reflector in the form of a hollow cylinder located above the chlorine outlet pipe coaxially with the latter, an overflow pipe and a water inlet check valve.

A disadvantage of the known device is the inadmissibility of setting the water level in the mixer below the upper end of the chlorine outlet pipe, which corresponds to the supply of dry chlorine to the ejector, due to significant losses of water technologically prepared for chlorination due to the need for its constant discharge from the mixer into the sewer, since the output tube into the ejector along with chlorine is not possible.

The purpose of the invention is to increase reliability, increase the operational life of the chlorinator and the exclusion of technological losses prepared for chlorination of water during ejection of dry chlorine.

The problem is solved in that in a chlorinator containing a filter, a shut-off valve, a control valve, lower and upper chlorine pipelines for supplying chlorine gas to a rotameter and mixer, respectively, with an overflow pipe for discharging water and an outlet pipe for supplying chlorine gas to the ejector, mains and water supply lines, a collector is installed on the water drainage line from the mixer, containing a drainage ejector located on the water supply line, the outlet of which is connected to the output line to the water supply system to the mixer, while the ejection input the drain ejector is connected in series with the water drain control valve and the blocking check valve, the input of which, as well as the input of the shutoff check valve installed on the water outlet line to the discharge chute, is connected to the water drain line from the mixer.

Figure 1 shows a chlorinator, a General view;

figure 2 - collector design, General view.

The chlorinator consists of a filter 1, a pressure gauge 2, a control valve 3, a rotameter 4, a mixer 5, in which an output pipe 6 for chlorine is placed, as well as an overflow pipe 7, placed under a glass cap 8, which are mounted in the mixer 5 on the bottom cover 9. The output pipe 6 for chlorine is connected to the supply line of chlorine 10 to the ejector 11, a shut-off valve 12 is installed in front of the filter 1 on the supply line of chlorine gas 12. The device is also equipped with a line 13 of the water chlorination system and a line 14 of the water supply system to the mixer, a water supply line for chlorine 15 through the control valve 16 to the chlorination ejector 11, which is connected to the outlet of the chlorinated water 17 at the outlet, the water supply line 18 through the control valve 19 to the mixer 5, the lower chlorine pipe 20, the upper chlorine pipe 21, the outlet of which is connected to the upper cover 22. A collector 24 is installed on the water drainage line from mixer 23, having a water supply line 25 through a control valve 26 from line 14, an output line 27 to the water supply system to the mixer, and also a water output line 28 to the discharge tray. On the water supply line 25 in the collector 24, an outlet ejector 29 is installed, the output of which is connected to the output line 27, and its ejection input is connected in series with the control valve for the drainage 30 and the non-return valve blocking the water flow 31 in the absence of an ejection, the input of which is the same as and a check valve 32 for shutting off the water flow from the discharge chute installed on line 28 is connected to a line 23 for discharging water from the mixer 5.

Chlorinator works as follows.

When the shut-off valve 12 is open, gaseous chlorine, passing through the filter 1, control valve 3, the lower chlorine line 20, the flowmeter 4, the upper chlorine line 21, enters the mixer 5 through the hole in the upper cover 22. At the same time, from the water line 14 through the water supply line 18 and a hole in the bottom cover 9, water is supplied to the mixer 5, the surface layer of which is set below the level of the upper end of the outlet pipe 6 due to its discharge into the collector 24 along the water drainage line from the mixer 23, and along the supply line 15, water is supplied to the ejector 11 to ensure ejection. In this case, dry chlorine gas is sucked into the ejector 11 from the mixer 5 through the outlet pipe 6 and the chlorine supply line 10, where it is mixed with water from the line 13. As a result of these processes, chlorinated water enters the discharge line 17.

The water is discharged from the mixer 5 to the collector 24 by its suction from the overflow pipe 7 along the drain line 23 through the open blocking check valve 31 and the water drain control valve 30 to the drain ejector 29 due to the presence of ejection created by the flow of water flowing into the drain ejector 29 from the line 25 and flowing from it to the output line 27.

If there is no ejection in the chlorination ejector 11 and outlet ejector 29 (emergency), the water entering the mixer 5 through the supply line 18 will be squeezed out of it and the chlorine backpressure generated in the mixer 5 into the overflow pipe 7, the drain line 23 through the opening in this situation check valve 32 overlap in the discharge tray and further into the sewer. In this situation, the non-return check valve 31 will be closed by the back pressure of water in the ejector of the outlet 29.

Thus, during chlorination, the absorption of dry chlorine into the chlorination ejector 11 is ensured without technological losses of water prepared for the chlorination process, and in an emergency situation, it is possible to drain the water squeezed out from the mixer 5 into the discharge chute.
