Description

Maintenance-free delivery system driven by high-pressure fluid

technical field

The invention relates to a maintenance-free conveying system driven by high-pressure fluid, which can be used for energy recovery of high-pressure and high-temperature fluid in the process of emptying industrial high-pressure fluid.

Background technique

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.

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).

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. 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).

Maintenance-free Compact Retrieval System for Hazardous Environments and Its Working Method (201110284199.1) The structure is too simple and compact, so the efficiency is low and it can only be used for small-scale liquid transfer.

In short, 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 .

The system includes an energy storage tank 1 for storing fluid, a waste liquid pool 11, a target pool 8, a control cabinet 12, a drive transduction tank 4 containing a drive piston 3, and an air contained below the drive transduction tank 4. The gas-liquid conversion tank 7 of the liquid piston 6, and a connecting rod 5 connected to the driving piston 3 and the gas-liquid piston 6, the waste liquid pool 11 is connected to the axial tube bundle Q of a chrysanthemum vortex valve J, and the chrysanthemum vortex valve The tangential tube bundle P of J is communicated with the chamber below the piston of the gas-liquid transduction tank 7 via a tee 15; the target pool 8 is connected to the tangential tube bundle P of another chrysanthemum swirl valve J, which The axial tube bundle Q is communicated with the chamber below the piston of the gas-liquid transducing tank 7 via the above-mentioned tee 15;

The energy storage tank 1 is respectively communicated with the upper and lower chambers of the drive transduction tank 4 through the two-way switching valve 2 controlled by the control cabinet 12; Controlled by the control cabinet 12;

The axial tube Z of the above-mentioned vortex valve W includes a spinal canal section i, the large end of which is connected to the disc structure X, and the small end is connected to a transition tube b, and the other end of the transition tube b is connected to the straight tube section a, and the diameter of the small head end of the spinal canal segment i is smaller than the diameter of the straight tube segment a.

The disk structure X of the above-mentioned vortex valve W is composed of the front cavity plate e, the rear cavity plate h and the annular arc plate g connecting the front and rear cavity plates, and the curvature of the annular arc plate g is the same as that of the tangential tube Y same curvature.

The inner surfaces of the front and rear cavity plates e and h of the vortex valve W are also provided with arc-shaped guide fins.

The above-mentioned guide fins include short guide fins c and long guide fins d, and the short guide fins c and long guide fins d are alternately arranged at the front and rear with the axis of the disc structure X as the center The inner side of cavity plate e, h.

The specific structure of the above-mentioned tangential tube Y connected to the tangential tube bundle P is as follows: the tangential tube Y is first connected to a 90-degree elbow, and the axis direction of the other port of the 90-degree elbow is parallel to the axial direction of the disc structure ; The other port of the 90-degree elbow is connected to the second 90-degree elbow through a straight line; and the axis direction of the other port of the second 90-degree elbow is perpendicular to the axial direction of the tangential tube bundle P, and the Another port is connected to the side of the tangential tube bundle P.

The vortex valve W of the present invention is shown in Figure 3-7,

Straight pipe section a and vertebral canal section i are connected by gradient pipe b, 4 pieces of short guide fins c and 4 pieces of long guide fins d are installed on the front cavity plate e and the rear cavity plate h, and the short guide fins c and the long guide fins d are placed at intervals of 45° around the central tube axis, and there is a gap between the long guide fins d on the front and rear cavity plates, and the length of the gap is not less than 50% of the distance between the front and rear cavity plates; The end of the tangential tube Y is the nozzle f of the tangential tube.

When the fluid flows in from the tangential tube Y, a swirl flow is formed in the vortex cavity, and a forced vortex and a free vortex are formed radially from the center. The reverse resistance is mainly determined by the strength of the forced vortex. Generally, the radius of the forced vortex is not larger than that of the vortex. 30% of the radius of the cavity. In order to enhance the strength and range of the forced vortex in the vortex cavity, the structure of short guide fins c and long guide fins d is added. Swirl flow is formed. When the swirl flow passes through the short guide fin c and the long guide fin d, a segmental swirl flow is formed, which causes the fluid to be affected by the space between the short guide fin c and the long guide fin d during the rotation process. Driven by the fluid between the channels, the strength of the swirling flow is continuously enhanced, and the group six of the reverse flow is increased;

After the fluid flows through the central tube and enters the vortex cavity, the fluid is divided into eight branches under the diversion action of the short guide fin c and the long guide fin d, and flows radially to the arc plate g, then flows out through the tangential tube , the fluid resistance is small.

As shown in Figure 2, the two-way switching valve 2 of the present invention includes a main pipe 13-a, and the main pipe 13-a is respectively connected to the side branch pipe 13-c and the main branch pipe 13-d through the valve core 13-b; by rotating the valve core 13- b for commutation.

The working principle of the present invention is as follows:

In order to make full use of the residual pressure energy of the high-pressure exhaust gas, the high-pressure gas energy storage tank 1 is used to store the high-pressure gas, and the high-pressure gas is controlled to enter the drive transduction tank 4 through the two-way switching valve 2;

When the punching process is in progress, the two-way switching valve 2 turns to the upper chamber of the drive transduction tank 4, high-pressure gas enters, and at the same time the exhaust valve 14 is opened, and the driving piston 3 drives the gas-liquid transduction tank 7 under the drive of the connecting rod 5 The middle gas-liquid piston 6 moves downward;

The front chrysanthemum-type vortex group 9 and the rear chrysanthemum-type vortex group 10 include at least one chrysanthemum-type vortex valve, and the chrysanthemum-type vortex valve J has two inlets and outlets, which are respectively a tangential tube bundle P and an axial tube bundle Q, as shown in Figure 3 Show. In Figure 3a, when the liquid flows from A to B, the liquid is divided into six streams at the tangential inlet of each vortex valve, enters the vortex chamber, flows out through the central tube, and converges to the outlet pipeline. After the fluid enters tangentially, a strong rotating flow is formed in the chamber, and the fluid resistance is relatively large; in Figure 3b, when the liquid flows from A to B, the liquid is divided into six streams at the entrance of the center tube of each vortex valve, and enters the vortex chamber through The tangential tubes flow out, converging into the outlet line. After the fluid central tube enters, a distributed flow is formed in the chamber, and the fluid is relatively small. The flow resistance formed by the two inlets and outlets of each chrysanthemum vortex valve of the front and rear chrysanthemum vortex groups 9 and 10 is quite different;

The axial tube bundle Q of the chrysanthemum-type vortex valve W in the front chrysanthemum-type vortex group 9 is connected to the waste liquid pool 11, and the tangential tube bundle P is connected to the tee 15;

The axial tangential tube bundle Q of the chrysanthemum vortex valve W in the rear chrysanthemum vortex group 10 is connected to the tee 15 , and the tangential tube bundle P is connected to the target pool 8 .

When the liquid is pushed downward by the gas-liquid piston 6 in the gas-liquid transducing tank 7, the liquid forms a split flow at the outlet of the tee 15. Since the flow direction of the front chrysanthemum vortex valve group 9 is tangential to the center at this time, it presents high resistance characteristics; then the chrysanthemum-type vortex valve group 10 now flows from the center to the tangential direction, so it presents low resistance characteristics; the fluid flow tends to flow with low resistance, so when the gas-liquid piston 6 presses down, the gas-liquid transduction tank 7 The waste liquid flows to the target pool 8 through the rear chrysanthemum vortex valve group;

When the liquid suction process is in progress, the two-way switching valve 2 turns to drive the lower chamber of the transduction tank 4, high-pressure gas enters, and at the same time, the exhaust valve 13 is opened, and the driving piston 3 is driven by the lower high-pressure gas to drive the connecting rod 5 to move upward. At the same time, the gas-liquid piston 6 in the gas-liquid transduction tank 7 moves upward, a certain vacuum is formed in the lower layer of the gas-liquid transduction tank 7, and the liquid is sucked into the gas-liquid transduction tank 7. , because the flow direction of the front chrysanthemum-type vortex valve group 9 is from the center to the tangential direction at this time, so it presents low resistance characteristics; while the flow direction of the rear chrysanthemum-type vortex valve group 10 is tangential to the center at this time, so it presents high resistance characteristics; the fluid flow tends to be low Resistance flow, so when the gas-liquid piston 6 absorbs liquid upward, the waste liquid in the waste liquid pool 11 flows through the front chrysanthemum type vortex valve group 9 as in the gas-liquid transducing tank 7; the whole process can be controlled by the control cabinet 12 according to the two liquid levels The signal of the meter is used to precisely control each valve.

The above process is reciprocated to realize the transportation of liquid. There are no moving parts in the transportation core device, and the transportation efficiency is high, the stability is good, and it can work continuously for a long time without maintenance. It can be used to transport dangerous and radioactive waste liquid.
