Wind-heating two-phase flow device and method

Abstract

The invention discloses a wind-heating two-phase flow device and method. The device employs the high-intensity flow friction effect of a vertical pipe (or inclined pipe) gas-liquid two-phase slug flowunder the condition of a large gas-liquid ratio, converts the mechanical energy of wind power into heat energy, and achieves wind heating; and main body components of the device comprise a wind powerimpeller, a transmission, a movable scroll compressor disc, a fixed scroll compressor disc, a two-phase flow heating pipe and a gas-liquid separator, and auxiliary components comprise a connecting pipe and a valve. The wind power impeller and the transmission are connected with the movable scroll compressor disc and the static scroll compressor disc through shafts, replace a motor of a scroll compressor to drive the movable and static scroll compressor discs, and pressurize gas through wind power. The pressurized gas enters the two-phase flow heating pipe to form gas-liquid two-phase slug flow with a large gas-liquid ratio together with liquid in the two-phase flow heating pipe, wind energy is converted into heat energy through the high-strength friction effect, and a wind heating way isexpanded.

Description

technical field [0001] The invention belongs to the technical field of wind energy utilization, in particular to a two-phase flow device and method for heating by wind. Background technique [0002] Wind energy is a renewable and clean energy, and the effective use of wind energy is a hot spot in energy utilization. my country has huge wind energy reserves. It is estimated that the available wind energy on land is about 250,000 MW, and the available wind energy in sea areas is about 750,000 MW. The monsoon caused by the earth's rotation from west to east, wind energy can last for several months in some areas, and has the characteristics of continuous use during day and night, which has its advantages compared with solar energy that can only be used during the day. Relying on wind turbines to convert wind energy into electrical energy is the most common form of wind energy utilization, and wind heating is another form of wind energy utilization. Wind heating technology conv...

Problems solved by technology

The first wind heating method is to generate wind power first, and then heat the electric energy through the resistance wire. This method belongs to indirect heating, and the efficiency of converting wind energy into heat energy is not high.

The second wind heating method is to use a wind turbine to drive an air compressor to compress the air and then release heat. The principle of this method is to use the expansion of gas to release heat, and the efficiency of converting wind energy into heat energy is not high.

The third wind heating method is to drive the agitator to rotate at a high speed by the wind turbine and stir the liquid to heat. The principle of this method is to use the friction between the agitator and the liquid to generate heat, and the efficiency of converting wind energy into heat energy is relatively high, but The agitator rotates at a high speed in the liquid for a long time, which is easy to cause the wear of the rotating shaft and cause vibration

The fourth wind heating method is to use wind force to rub solid materials to generate heat. This method has a relatively high efficiency of converting wind energy into heat energy, but the friction of solid materials will inevitably cause wear of the materials, and long-term friction will cause the properties of solid materials to attenuate.

The fifth wind heating method is to use the wind to drive the hydraulic pump, so that the hydraulic oil is sprayed from the small hole at high speed. In the process, the heat is generated through friction and impact, and the wind energy is converted into heat energy. Transmission principle, high equipment cost and difficult operation
