A temperature non-uniformity measuring device for a marine steam heat accumulator

Abstract

The invention discloses a temperature non-uniformity measuring device for a marine steam heat accumulator, which comprises a cylindrical horizontally placed marine steam heat accumulator cylinder, a water space discharge steam header installed at the bottom of the interior, and a water space discharge steam The header is connected to the external bypass pipeline through the steam charging pipeline. There are three sensors and a steam discharge pipeline on the outer surface of the marine steam heat accumulator cylinder, and one end of two multi-point thermocouples is placed in the marine steam heat accumulator cylinder. Inside the body, the other end protrudes from the cylinder of the marine steam heat accumulator and connects to the external data acquisition instrument through the signal line respectively. One of the thermocouples is placed next to the steam discharge header in the water space, and the other is far away from the steam discharge header in the water space. The cylinder body of the steam accumulator is also provided with a water level gauge, the bottom of the cylinder body of the steam accumulator is provided with a drainage pipeline and a sewage pipeline, and the cylinder body of the steam accumulator is also connected with a water supply pipeline. The beneficial effect of the invention is that the device is simple, and the temperature distribution in the heat accumulator can be presented more conveniently and truly through the device.

Description

technical field [0001] The invention belongs to the technical field of steam heat accumulators, and relates to a temperature non-uniformity measuring device for marine steam heat accumulators. Background technique [0002] The marine steam accumulator is one of the important components of the steam catapult system on the aircraft carrier. It has the characteristics of short charging and discharging time and large instantaneous steam output. It is the key equipment to realize the transformation from large steam supply capacity to maximum steam supply capacity , its application not only optimizes the capacity of the boiler, but also alleviates the impact of load disturbance on the boiler and improves the maneuverability of the ship. [0003] The steam charging process of the marine steam accumulator is a thermodynamic process in which the heated steam mixes with the low-temperature saturated water in the accumulator and performs forced convective heat exchange. Whether the mix...
