The invention provides a reactor internal and external pressure and pressure difference measuring device with a water wall internal part. The device includes a water wall section, the water wall section comprises a shell and a water wall, the water wall is located in the shell, an overhaul interlayer is arranged between the water wall and the shell, the shell is in flange connection with an interlayer pressure tapping pipeline and a water wall internal pressure tapping pipeline, the water wall internal pressure tapping pipeline penetrates through the shell, is close to the water wall and is bent downwards, and the water wall internal pressure tapping pipeline is provided with an expansion bend in the overhaul interlayer; a first pressure transmitter and a second pressure transmitter are respectively connected to the interlayer pressure tapping pipeline and the water wall internal pressure tapping pipeline, and a pressure difference transmitter is connected between the interlayer pressure tapping pipeline and the water wall internal pressure tapping pipeline through a connecting pipeline; and a pressure tapping pipeline in the water wall is provided with high-pressure gas purge. Thedevice is precise in measurement and long in service life, the risk that the water wall internal pressure tapping pipeline in the overhaul interlayer is deformed and damaged due to heating is reduced, and the problem of fly ash entry or slag blockage is solved.
Description
technical field [0001] The invention relates to a device for measuring internal and external pressure and pressure difference of a reactor with water-cooled wall internals, and belongs to the technical field of measuring the internal and external pressure and differential pressure of a reactor with water-cooled wall internals for high-temperature reactors. Background technique [0002] In chemical production, for high-temperature reactors with water-cooled wall sections, due to the high temperature inside the water-cooled wall section, and the high-temperature gas contains ash or slag, the measurement environment is harsh, so there is a certain difficulty in pressure measurement, or measurement accuracy Not enough, or easy to block and damage, but the internal pressure of the reactor with water-cooled wall internals, the external pressure of the water-cooled wall and the pressure difference between them have important guiding significance for the operation.
