A method of liquid transfer using a vortex valve

Abstract

A liquid transferring method through vortex valves comprises the following steps that the vortex valves are assembled to form chrysanthemum-type vortex valves, particularly, axial pipes of the vortex valves are communicated with the outer lateral surface of an axial pipe bundle, tangential pipes are communicated with the outer lateral surface of a tangential pipe bundle, and then one chrysanthemum-type vortex valve is obtained; a waste liquid pool is connected with the axial pipe bundle of one chrysanthemum-type vortex valve, and the tangential pipe bundle of the chrysanthemum-type vortex valve is connected with a three-way joint; a target pool is connected with the tangential pipe bundle of the other chrysanthemum-type vortex valve, and the axial pipe bundle of the chrysanthemum-type vortex valve is connected with the three-way joint; the three-way joint is connected with a cavity under a piston of an air-liquid transduction tank; high-pressure fluid is used for driving the piston to move back and forth and then waste liquid is transferred to the target pool. The liquid transferring method through the vortex valves can achieve the liquid transferring process driven through high-pressure air and liquid, the process does not need a rotary device, operation for a long time is achieved, maintenance is not needed, long-distance conveying of liquid can be carried out, conveying fluid amount within the unit time is stable, and radioactive industrial waste water or industrial waste water harmful to the human body can be conveyed. Non-Newtonian fluid with solid particles such as mud and coal slurry can be conveyed.

Description

technical field [0001] The invention relates to a liquid transfer method, in particular to a liquid transfer method using a vortex valve, and belongs to the technical field of high-pressure high-temperature fluid energy recovery and utilization. Background technique [0002] In large-scale industrial production activities, there is usually a need to discharge high-temperature and high-pressure liquids or gases, and these high-temperature and high-pressure fluids contain huge energy. If they are directly discharged, not only will waste gas and liquid be produced to pollute the environment, but also cause resource pollution. Waste does not meet the requirements of low-carbon environmental protection and the trend of energy saving and emission reduction.

Problems solved by technology

[0002] In large-scale industrial production activities, there is usually a need to discharge high-temperature and high-pressure liquids or gases, and these high-temperature and high-pressure fluids contain huge energy. If they are directly discharged, not only will waste gas and liquid be produced to pollute the environment, but also resources will be polluted. Waste, does not meet the requirements of low-carbon environmental protection and the trend of energy saving and emission reduction

[0003] Traditionally, high-pressure exhaust gas drives the turbine to rotate and convert the residual pressure energy of the exhaust gas into rotating mechanical energy. This gas residual pressure energy recovery technology has low energy recovery efficiency due to multiple conversions of energy (a kind of energy recovery for blast furnace exhaust gas) Turbocharger set CN102373305A)

[0004] The liquid residual pressure energy recovery device uses the drive motor to drive the rotor to realize the energy exchange of high and low pressure fluids. Its energy recovery efficiency is high, but the recovery system often needs to be driven by a motor, and the control of the whole system is relatively complicated. The core device in the recovery process has strict requirements on sealing. High, in actual use, once the sealing structure design is unreasonable or the use process fails, it will directly lead to a significant reduction in recovery efficiency (a liquid residual pressure energy recovery device CN101865191A)

[0005] In short, the traditional residual pressure energy recovery is often only for a single medium fluid, such as gas or liquid residual pressure energy recovery, and there are rotating parts in the system, the failure rate is high, and because the energy is converted twice, the recovery efficiency is low
