A kind of chrysanthemum type vortex valve and its liquid transfer method

Abstract

Disclosed are a chrysanthemum-type vortex valve and a liquid transfer method thereof. The chrysanthemum-type vortex valve comprises at least three vortex valve bodies, tangential pipe bundles with one ends closed and axial pipe bundles with one ends closed. Axial pipes of the vortex valve bodies are all communicated to the outer side faces of the axial pipe bundles while tangential pipes of the same are all communicated to the outer side faces of the tangential pipe bundles. The method includes that a waste liquid pool is connected with the axial pipe bundle of one chrysanthemum-type vortex valve body, and the tangential pipe bundle of the chrysanthemum-type vortex valve body is connected with a three-way joint; a target pool is connected with the tangential pipe bundle of another chrysanthemum-type vortex valve body, and the axial pipe bundle of the chrysanthemum-type vortex valve body is connected with the three-way joint; the three-way joint is further connected to a cavity below a piston of a gas-liquid energy changing tank; waster liquid is transferred into the target pool by enabling high-pressure fluid to drive the piston to be in reciprocating motion. By the chrysanthemum-type vortex valve and the liquid transfer method thereof, the process of liquid transfer driven by high-pressure gas and liquid can be realized, a rotating device is not needed in the process, long-time running can be realized, maintenance is not needed, remote-distance delivery of liquid can be realized, delivery flow is stable, industrial wastewater which is radioactive or harmful to human body can be delivered, and non-Newtonian fluid, with solid particles, like mud and coal slurry can be delivered.

Description

technical field [0001] The invention relates to a component used for energy recovery of high-pressure and high-temperature fluids, in particular to a chrysanthemum-type vortex valve and a liquid transfer method thereof, belonging to the technical field of 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. [0003] Traditionally, the 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...

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, the 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 recoverer uses the driving 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. Higher, 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
