SU1354054A1 - Device for sampling liquid from pipeline - Google Patents

Abstract

The device relates to the technique of sampling fluid from vertical pipelines with a falling stream and can be used in the chemical and petrochemical industry. The aim of the invention is to increase the reliability of samples and speed up the sampling process. A positive effect is achieved by creating a favorable hydrodynamic environment in the sampling zone, which is provided by organizing the ejection of air from the sampling tank 7, and using the kinetic energy of the analyzed medium to create the required vacuum. To this end, the device is equipped with an additional tube 5 connected through a seal 3 with a hole 6 in the rear part of the intake tube I. 1 sludge. cl

Description

t

The invention relates to engineering. sampling fluid and can be used in the chemical, petrochemical and other industries of the industry, mainly for sampling from vertical pipelines with a falling stream.

The purpose of the invention is to increase the reliability of the sample and speed up the selection process.

The drawing shows the proposed device, a longitudinal section with

The device contains a suction tube 1 with a gap 2 in its side surface. The intake tube 1 is installed in the pipeline so that the gap in its side surface is directed towards the flow of the analyzed liquid. The free end of the intake pipe 1S, which is outside the pipeline, is provided with a seal 3. Inside the intake pipe 1, a drain 4 and an additional 5 pipe are placed. In the aft part of the intake pipe there is a through hole 5 connected through an additional pipe 5 with a capacity of 7 to collect. hermetically mounted on the pipeline with a flange of 8 "

The device works as follows.

In the working position, the flange 8 of the sampler is attracted to a corresponding device for sampling fluid from the pipeline, which contains a downhole tube with a slit on the side, placed in the pipeline with a slit facing the flow, a drain tube placed inside the intake and a sampling container, In order to increase the reliability of the sample and the effectiveness of the sampling process, the intake line is made with a hole in the stern of its side surface, provided with a seal at its free end and a flange. Supplementary tube, place

to the existing flange of the pipeline mounting pipe under the action of an existing in the intake pipe, one end in the vacuum flow, thereby ensuring the required tightness. Through the opening 6 and the tube 5, the vacuum is transferred to the container 7 for collection. samples. Sample fluid from flow through

which, through a seal at its biased end, is connected to a container for collecting samples, and the other with a hole in the stern of the lateral surface of the sampling tube.

the slot 2 in the intake tube 1 and the drain tube 4 enters the receiving tank 7, which is under vacuum.

 After filling capacity 7 with required

 is removed from the pipeline and the nozzle is plugged.

The proposed device is simple and

10 reliable in operation. The presence of an aperture in the aft part of the intake tube associated with the receiving tank makes it possible to increase the sampling rate. This reduces the effect of hydrodynamic inhomogeneities in the sampling zone, which contributes to an increase in the reliability of the sample.
