Problems solved by technology

However, in actual use, the flowmeter is easy to be blocked, has a large maintenance workload, is easily damaged, and has a short service life. Moreover, due to the chaotic arrangement of the total pressure pipe and the static pressure pipe, the measurement results still have large errors and low accuracy. question

Embodiment Construction

[0017] Such as Figure 1-Figure 3 As shown, the circular pipeline full-section flow measuring device of the present invention includes four groups of sampling tubes arranged orthogonally along the circumference, each group of sampling tubes includes a total pressure tube 1 and a static pressure tube 2, and the total pressure tube 1 and the static pressure tube 2 adopt Stainless steel pipe, total pressure pipe 1 and static pressure pipe 2 are arranged back to back, total pressure pipe 1 is provided with several total pressure sampling holes 11 in the windward direction, and static pressure pipe 2 is provided with several static pressure sampling holes 21 in the opposite direction. The present invention is mainly applicable to circular pipes with an inner diameter of Φ3001mm-Φ8000mm. The number of sampling holes is determined according to the inner diameter of the circular pipe. The larger the inner diameter, the more the number of settings. There are 4 or 5, and the setting pos...

Abstract

The invention belongs to the technical field of flue gas flow measurement equipment, and aims to provide a whole-section flow measurement device for a circular pipeline, which is unlikely to be blocked, high in measurement accuracy, long in service life, stable and reliable. Four bundles of sampling pipes are circumferentially and orthogonally distributed on the same section in the circular pipeline, and each bundle of sampling pipes comprises a total pressure pipe and a static pressure pipe, wherein the total pressure pipes and the static pressure pipes are arranged back to back, a plurality of total pressure sampling holes are formed in the total pressure pipes in the windward direction, and a plurality of static pressure sampling holes are formed in the static pressure pipes in the opposite direction, so that a measurement result is accurate. A purging device is also arranged to periodically reversely purge the total pressure pipes, the static pressure pipes and each outlet pipe, so that an anti-blocking ash removal function is realized, the device is unlikely to be blocked, low in maintenance amount, stable, reliable and long in service life, the flow velocity (flow) of flue gas in an industrial exhaust pipeline which is complex in arrangement and has a disordered flow field can be continuously and accurately measured on line, and the requirements of the environmental protection department on online exhaust emission monitoring accuracy, continuity and reliability can be met.

Description

technical field [0001] The invention belongs to the technical field of flue gas flow measurement equipment, and in particular relates to a circular pipe full-section flow measurement device. Background technique [0002] At present, the general method of measuring the flow rate (flow rate) of industrial exhaust gas is to use the traditional one sampling point (point measurement) or several measurement points (line measurement) measurement method, which can only be used under the condition of uniform flow field or relatively uniform flow field. Accurately measure the flue gas flow. If the flow field is uneven or turbulent, neither point measurement nor line flow measurement can accurately measure the average flow velocity at the cross-section. However, due to the actual conditions of the industrial waste gas discharge pipelines in the electric power, petroleum and chemical industries, such as process and space constraints, it is difficult for the waste gas pipelines to achiev...
