Description

The chlorinator, which is a system of instruments for controlling and measuring the flow rate and capacity of the prod rbrabd at the amo} 50DA, must be careful - (The following condition is the con stant pressure at the outlet of the control section, i.e. the chlorine concentration d the two paths on which the installation: ovden meter1} body, arkhoda hlrr; shortening the flow rate for gas in any form of the control plot; and preserving the constancy of pressure in the loop to the control region.

Of particular importance for the preservation of the second condition is the unchanged value of the orifice of the diaphragm or capillary, which creates pressure in the differential pressure gauge, on which the chlorine flow rate.

To create conditions for the uniformity of gas flow, we usually use check valves of an orb of the device, do not mix chlorine with water and xlr meters, fill 1e sulfur with acid, carbon tetrachloride, water or other liquid M;

The proposed vacuum chlorinator is of the type of chlorinator described in ed. St. , № 51263. A diagram of it is depicted in the drawing.

The instrument consists of a glass tube that has an elbow; a knee: a right-high pressure and a left-low pressure. The pipe has a tube; b nozzles. A connection pipe / on the high pressure knee (n, equal) is connected to a control valve, a pressure reducing valve, or a device that creates the condition for uniform gas flow. Nozzle 2 on the left knee is connected with a water jet ejector. The nozzle 5 on the same left knee passes through the body of the right knee of the tube and is so chambered that it is necessary to attach it to it in the capillary's small jacket, which measures the amount of gas required for a section.

by means of the rubber coupling. The unit device creates the convenience of cleaning and changing the capillary, since access to it is opened by removing only one cap.

The manufacture of a capillary from glass or another anticorrosive material ensures that the gas flow is uniform.

At the top, the tube has a tightly sealed expansion 5, which serves to dampen the pulsations that can occur in the event of very strong fluctuations in the operation of the water jet ejector.

From the bottom, the tube has a pipe 6, by which it is connected to a water tank; A constant level is maintained in the tank by means of a ball float valve connected to the aqueduct. A rubber tube with a clip is attached to nozzle 6 to adjust the amount of water. The end of the nozzle 6 is folded upward and ends with a check valve. The end of this tube (together with the end of the drain tube from the water tank diverted to the sewage system) is covered with a glass cap.

The tank, in which a constant water level is maintained, is strengthened at such a height that the difference between the water level markers in it and the level of the drain valve of the nozzle 2 is mm.

On the right knee of the tube there are divisions, and the zero of the scale coincides with the drain valve of the pipe 2.

When the ejector is put into operation, the water from the water tank with a constant level rises through pipe 6 and, due to vacuum, fills the right and left knees of the tube to the level of the drain valve pipe 2, i.e. to zero. Higher water can rise and a constant vacuum equal to self is established in the device.

When starting the chlorine from the regulating valve, depending on the degree of opening of the crane, the water level in the right knee decreases, and the chlorine, the output from the capillary, acquires a constant vacuum equal to I. The amount of water sucked is adjusted by clamp 7 on the nozzle 6 so that so that the water level in the right knee of the device does not fall below the drain pipe 2. Variations in the work of the ejector can cause a variable inflow of water from a water tank having a constant level, but the vacuum in the right knee of the device remains constant, equal to I 200 mm either due to the difference soprotivleiy be overcome sucks water, have a very small value).

The determination of the chlorine consumption is given by a division reading, at which the chlorine level in the left knee is established.

The scale on the device is in millimeters and the device must be calibrated depending on the size of the capillary channel. The scale readings are constant and independent of the gas pressure, since they are made up for a vacuum that remains unchanged.

Due to the fact that water, although insignificantly, flows from the nozzle 6 to the nozzle 2, it always remains transparent. The device does not require any indicator liquid, since the meter is filled with water and the zero is automatically kept constant.

Subject invention

Vacuum chlorinator, according to ed. St. No. 51263, characterized in that, in order to use the dosing chamber for simultaneous {Tugulation of the flow of liquid and gas, the chamber is designed as a rheometer and provided with a nozzle for supplying chlorinated liquid to it.
