SU130492A1 - Device for sampling enriched condensate samples - Google Patents

Description

A device is known for sampling a saturated steam condensate sample enriched with salts using a multistage droplet connected with a magnetral tube, a concentrator with a senator and a heat exchanger connected with a tube.

The described device, in contrast to the current, makes it possible to automate the multiplicity of the enrichment of a sample of condensate with a stable multislung choke, depending only on the initial pressure of the test steam.

For this purpose, the heat exchanger is installed in an inertly multi-choked choke, and the reduced pressure vapor produced in the concentrator after the separator is supplied to the heat exchanger for cooling and partial condensation of the test bunch.

The drawing shows a diagram of the device.

The device consists of a serially installed x on the pipe; a tube from the main pipe: a heat exchanger; multiple throttle 2; linear separator 3, enclosed in close the casing 4 (casing 4, and the senator / i form together a hub). In the lower part of the casing 4 there are tubes 5 with a developed heating surface and an outlet choke 6 for draining condensate into the atmosphere, leaving the separator 3 in series with the separator once. Additional single-stage choke 7 for draining condensate to salimeter sensor 8. Multi-stage choke 2 is designed so that it reduces the pressure of the ram from the main line to sky pressure sufficient only to overcome the further separator and heat sink

High-pressure saturated steam taken out of the line, falling into a multi-stage throttle 2, reduces its pressure, increases and self-irrigates, providing an accumulation of salts into the co-condensate, which is then separated in the separator 3 and through the throttle 7 is discharged to the salt gauge 8. The vapor after pressure of the multistage droplets 2, leaves the separator 3 in the pitch of the closed casing 4. is released in the lower part of the condensate residue and is directed through the pipe 9 to the heat exchanger 1, partially condensing high pressure steam passing through the sampling tube; The reduced pressure steam is superheated and removed from the heat exchanger through the outlet 10 to the atmosphere.

With such a device, the multiplicity of enrichment of a sample of condensate with salt depends only on the initial pressure of the steam withdrawn from the line, regardless of the amount of condensate sampled, since the heat content of steam under reduced pressure after a stable multi-stage droplet 2 depends only on the initial heat content of the extracted high pressure steam.

Partial condensation of the sample creates favorable conditions for removing the majority of the gases present in the vapor, and therefore their relative effect on the specific conductivity of the enrichment salt of the condensate MP will be negligible.

Automatic equilibrium AC bridges with electronic amplifiers can be used as measuring instruments.

The described device can be applied, for example, in thermal power plants.
