SU46386A1 - A device to control the quality of saturated steam boilers - Google Patents

Description

The proposed device is intended to detect contamination of saturated steam boilers with boiler water containing alkaline salts.

The main part of the instrument is the U-shaped tube A, in which the condensate obtained from the controlled vapor is chemically tested.

In FIG. 1 shows schematically the main part of the device; FIG. 2-the same device with devices for automatic signaling about the presence of harmful impurities in the pair.

Inside the box there is a U-shaped tube L clamped on a loop with a two outlet tubes g and h; A rubber tube is attached to the end of the tube g, which serves to drain water that passes through the device; A glass square is attached to the tube h, to the upper end of which a rubber tube K is attached, diverting the suction through the tube / air into the second bend of the U-shaped tube and then through the tube g to the outside.

To the other end of the glass square t there is a tap / regulating the rate of water passing through the device, to which a glass square d is attached by a rubber tube, designed to pass condensate flowing from the cooler through the tube e partially into the device, and also to remove excess condensate along tube / drainage.

A glass tube C is inserted into the second leg of the U-shaped tube by means of a rubber stopper, into which, in turn, a split tube is inserted. The funnel D the end of which is strongly retracted to facilitate the flow of small droplets. The funnel B is filled with an alcohol solution of phenolphthalein.

Saturated steam from the boilers is passed through a refrigerator, from which condensate flows through pipes 6, d and g and enters the right knee of the appliance; ; Partially condensate together with air 5 is carried along tube k to the left knee, while excess condensate that is not passed by the tap into the device is discharged through tube.

In the right knee of the instrument, the water is shifted with the indicator fepolphthalein coming from the funnel B; The drip flow rate is adjusted with a funnel tap from 1 to 3 drops per minute.

In case of steam contamination with alkaline salts. always contained in the boiler water, the solution in the U-shaped tube is colored pink or red and drains from the appliance into the drain.

An alcoholic solution of phenolphthalein is prepared using raw alcohol or distilled denatured alcohol.

An electric lamp is mounted in the box to illuminate the device; The inner surface of the box is painted white or covered with white paper.

With the described device it is possible to arrange an electrical sound or light alarm (Fig. 2).

For this purpose, in the device one of the knees of the U-tube has an extension, with two opposite sides of this expansion forming bulging glasses; instead of blowing up the tube itself, you can cut off a part of the knee below the outlet tube and put on a metal extension / with two convex watch glasses on the remaining knee (Fig. 2).

An electric lamp L is installed on one side of these glasses, and on the other side there is a photocell placed in a box with a tube directed towards the rays passing through the convex glasses.

The photocell is assembled as shown in FIG. 2, and connected to the appropriate alarm.

In order to be able to simultaneously observe and automatically signal the presence of alkali salts in steam, the author suggests connecting in series two instruments, one of which is provided with an alarm and the second is used to directly observe the thickness of the color of the liquid obtained in the instrument.

The subject matter of the invention.

Claims (2)

1. A device for monitoring the quality of saturated steam of boilers by detecting the presence of alkaline salts of boiler water in a pair in a transparent U-shaped vessel for condensate obtained from the steam under investigation, characterized in that the U-shaped vessel is equipped with a funnel B with a solution of phenolphthalein designed for staining alkaline condensate in a red color. 2. In the device of claim 1, use a photocell connected electrically with a sound or light alarm to detect the presence of alkali salts in a pair. Fig /.
