Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
As shown in fig. 1, the multi-air source steam pressurizing device according to the embodiment of the invention comprises a low-pressure steam pipe 1 and a plurality of pressurizing pipes 2.
Specifically, as shown in fig. 1, the low-pressure steam pipe 1 may be filled with low-pressure steam, a plurality of through holes 111 are arranged on the peripheral wall of the low-pressure steam pipe 1 at intervals along the length direction thereof, a plurality of booster pipes 2 correspond to the plurality of through holes 111, one ends of the booster pipes 2 extend into the low-pressure steam pipe 1 through the corresponding through holes 111, and the other ends of the booster pipes 2 are communicated with a high-pressure steam source.
It can be appreciated that the pressurizing pipes 2 introduce high-pressure steam into the low-pressure steam pipe 1 to be mixed and pressurized with the low-pressure steam therein, and the pressurizing pipes 2 can realize multi-stage pressurizing, so that the pressurizing effect is good.
Further, in the actual use condition, the high pressure steam sources connected by the plurality of booster pipes 2 are different, two adjacent booster pipes 2 are communicated through a one-way flow pipe 3, and in the gas transmission direction of the low pressure steam pipe 1, the one-way flow pipe 3 allows the high pressure steam in the upper booster pipe 2 to flow to the lower booster pipe 2. Here, the upper stage booster pipe 2 and the lower stage booster pipe 2 are not specifically defined as the specific booster pipe 2, but are defined in terms of the boosting sequence, that is, in the flow direction of the low pressure steam, the upper stage booster pipe 2 is defined as the upstream booster pipe 2 and the lower stage booster pipe 2 is defined as the downstream booster pipe 2, taking two adjacent booster pipes 2 as examples.
It can be understood that, because the high-pressure steam sources communicated by the plurality of booster pipes 2 are different, the steam pressures in the different booster pipes are also different, and by communicating the unidirectional flow pipe 3 between the adjacent booster pipes 2, when redundant high-pressure steam exists in the upper booster pipe 2, the high-pressure steam can be introduced into the lower booster pipe 2 through the unidirectional flow pipe 3, so as to improve the steam pressure of the lower booster pipe 2, and avoid the waste of the high-pressure steam while being beneficial to improving the boosting effect. Preferably, the cross section area of the unidirectional flow pipe 3 along the flow passage in the gas transmission direction is gradually reduced, so that the flow velocity of the gas in the unidirectional flow pipe 3 is improved, and the impact force of the unidirectional flow pipe on the gas in the next stage of pressurizing pipe 2 is enhanced.
According to the multi-air source steam pressurizing device provided by the embodiment of the invention, the low-pressure steam pipe is externally connected with the plurality of pressurizing pipes which are arranged at intervals along the length direction of the low-pressure steam pipe, the plurality of pressurizing pipes are correspondingly communicated with different high-pressure steam sources, the unidirectional flow pipe is communicated between the two adjacent pressurizing pipes, and the unidirectional flow pipe allows high-pressure steam in the upper pressurizing pipe to flow into the lower pressurizing pipe, so that the plurality of pressurizing pipes can introduce high-pressure steam into the low-pressure steam pipe to realize multi-stage pressurizing, multi-gradient pressurizing of the low-pressure steam is realized, the pressurizing effect is ensured, and the arrangement of the unidirectional flow pipe can introduce redundant high-pressure steam in the upper pressurizing pipe into the lower pressurizing pipe so as to increase the steam pressure of the lower pressurizing pipe, and avoid high-pressure steam waste while improving the pressurizing effect.
Further, as shown in fig. 1, the low pressure steam pipe 1 includes a plurality of pressurizing sections including an outer air chamber 11 and a diffusion chamber 12, and in the gas transmission direction of the low pressure steam pipe 1, the front end of the diffusion chamber 12 communicates with the outer air chamber 11 and the cross-sectional area of the front end of the diffusion chamber 12 is smaller than that of the outer air chamber 11, and the diffusion chamber 12 of the upper pressurizing section of the adjacent pressurizing sections communicates with the outer air chamber 11 of the lower pressurizing section. Therefore, the outer air chamber 11 and the diffusion chamber 12 can be used as a conveying channel of low-pressure steam, and can be used for mixing high-pressure steam which is introduced from a pressurizing pipe, and the sectional area of the front end of the diffusion chamber 12 is smaller than that of the outer air chamber 11, so that the joint of the diffusion chamber 12 and the outer air chamber 11 can be throttled and pressurized, the steam flow speed and the impact force are improved, and the low-pressure steam and the high-pressure steam can be conveniently and efficiently mixed.
Further, as shown in fig. 1, the diffusion chamber 12 includes a connection pipe section 121 and a diffusion pipe section 122, the front end of the connection pipe section 121 is connected to the outer air chamber 11, the diffusion pipe section 122 is connected to the rear end of the connection pipe section 121, and the sectional area of the diffusion pipe section 122 gradually increases in a direction away from the connection pipe section. Thus, the progressively larger diffuser section 122 facilitates a slowing of the airflow rate so that the high pressure steam and the low pressure steam can be thoroughly mixed before flowing into the next booster section, improving the booster effect.
Further, as shown in fig. 1, through holes 111 are provided on the outer wall of the outer air chamber 11, and one end of the pressurizing pipe 2 extends into the outer air chamber 11 through the corresponding through hole 111 and communicates with the diffusion chamber 12. It will be appreciated that the high pressure steam introduced into the booster tube 2 forms a negative pressure during injection, and this negative pressure produces a suction effect on the low pressure steam of the external air chamber 11, resulting in an accelerated inflow of the low pressure steam, which is then mixed with the low pressure steam in the diffusion chamber 12, increasing the pressure of the low pressure steam.
Further, as shown in fig. 1, the booster pipe 2 includes an intake pipe section 21 and an injection pipe section 23, the intake pipe section 21 communicates with a high-pressure steam source, the injection pipe section 23 communicates with the low-pressure steam pipe 1, and the sectional area of the injection pipe section 23 is smaller than the sectional area of the intake pipe section 21. Therefore, when high-pressure steam flows into the jet pipe section 23 from the air inlet pipe section 21, a throttling and pressurizing process exists, the high-pressure steam can be ejected from the jet pipe section 23 at a high speed, and the formed negative pressure can generate stronger suction force on the low-pressure steam, so that the flow and mixing of the steam in the low-pressure steam pipe 1 are facilitated.
Preferably, as shown in fig. 1, the end of the air inlet pipe section 21 facing the injection pipe section 23 is provided with a conical section 22, and the cross-sectional area of the conical section 22 gradually decreases along the direction approaching the injection pipe section 23, so that the conical section can guide the air in the air inlet pipe section 21 to flow towards the inlet of the injection pipe section 23, improve the smoothness of the steam flowing between the air inlet pipe section 21 and the injection pipe section 23, and reduce the impact of the air flow on the pipe wall.
Further, as shown in fig. 1, a first throttle section is formed between the outer peripheral wall of the intake pipe section 21 and the inner peripheral wall of the low-pressure steam pipe 1, a second throttle section is formed between the outer peripheral wall of the injection pipe section 23 and the inner peripheral wall of the low-pressure steam pipe 1, a third throttle section is formed between the outer peripheral wall of the tapered section 22 and the inner peripheral wall of the low-pressure steam pipe 1, the third throttle section is located between the first throttle section and the second throttle section, and the sectional area of the third throttle section is smaller than the sectional area of the first throttle section, and the sectional area of the third throttle section is larger than the sectional area of the second throttle section.
It can be understood that when the low-pressure steam is continuously injected under the action of the negative pressure formed by the high-pressure steam sprayed out of the spray pipe section 23, the low-pressure steam sequentially flows through the first throttling section, the third throttling section and the second throttling section, the sectional area of the flow channel is continuously reduced, the flow speed of the gas is continuously accelerated, the high-speed low-pressure steam is more beneficial to improving the mixing efficiency of the high-pressure steam, and the utilization rate of the high-pressure steam is further improved.
Further, as shown in fig. 1, the end of the injection pipe section 23 far from the air inlet pipe section 21 is provided with an open section, and the sectional area of the open section is gradually increased along the direction far from the air inlet pipe section 21, so that the high-speed high-pressure steam injected by the injection pipe section 23 has a larger contact area with the low-pressure steam through the diffusion of the open section, and the mixing efficiency is improved.
