Three-inflection point U-shaped tube realizes gas volume expansion self-triggered time-delayed isobaric migration device

Abstract

The invention relates to a gas volume expansion self-triggering time-delay isobaric migration technology realized by a three-inflection-point U-type tube, in a temporary gas storage storehouse in a container filled with water, liquid level is decreased due to compressed air expansion or gas volume expansion when a gas is filled into the temporary gas storage storehouse, where in the temporary gas storage storehouse is semi-enclosed and is provided with an inverted opening, by use of the theory of communicating vessels of the U-type tube, when the liquid level in the temporary gas storage storehouse is lower than the lowest point of the U-type tube, a device is triggered, the gas in the temporary gas storage storehouse quickly passes through one time the U-type tube to enter a pressure vessel. The device can be used to realize the gas migration in the compressed air expansion process, controls a gas moving path, and can also be used for gas guiding, seabed natural gas collection and the like before heat and mass exchange of a chemical tower.

Description

Technical field [0001] The invention relates to a gas delay migration technology, in particular to a gas volume expansion self-triggering delay isobaric migration device realized by using a three-inflection point U-shaped tube. The U-shaped tube connector principle is used to automatically expand the gas volume to the level of the trigger position. Migrate to other places through the U-tube at one time. Background technique [0002] The current power load has a large peak and trough difference, and the power generation output and load demand of the power system are matched from time to time. If there is no energy storage equipment, conventional thermal power plants must be backed up, and the efficiency is reduced; wind farms need to abandon wind to achieve output adjustment. Waste wind resources. [0003] Energy storage technology plays an important role in the operation of the power grid. The introduction of energy storage can effectively realize demand-side management and elimin...

Problems solved by technology

[0004] Existing energy storage technologies include pumped storage technology, compressed air energy storage technology, flywheel energy storage technology, supercapacitor energy storage technology, battery energy storage technology, etc. Among them, compressed air energy storage is low in cost, large in capacity, and capable The characteristics of large-scale application have broad development prospects, but its limitation is that it needs to consume a lot of gas, generate carbon emissions, and have low efficiency, which limits its application and promotion

[0005] There is now adiabatic compressed air energy storage technology, which is characterized by no heat exchange between the gas and the outside world, that is, when the air is compressed with high density, the temperature of the gas storage chamber will rise sharply, and when the compressed air expands to do work, the temperature of the gas storage chamber will rise sharply again. Its advantage is that it will not cause energy loss, but its disadvantage is that the temperature in the gas storage chamber rises and falls frequently, which will have an adverse effect on the stability of the energy storage and deflation power generation process and the safe operation of the gas storage chamber
