[0041] The present invention provides the following embodiments

[0042] Example 1

[0043] The embodiment of the present invention provides a steam ejector and an ejection method, such as Figure 1-4 As shown, it comprises: a negative suction pipe 1, a steam injection pipe 2 is installed on the flange above the negative suction pipe 1, a steam generating assembly 4 is installed at one end of the steam injection pipe 2, and a silencer and speed reduction assembly 6 is installed at the other end of the steam injection pipe 2;

[0044] A steam regulating component is also included, and the steam regulating component is used to regulate the steam injected into the steam injection pipe 2.

[0045] The working principle and beneficial effects of the above technical solution are as follows: after adjusting the parameters of the steam injection pipe 2 to the required values, sufficient high-pressure steam is generated by the steam generating component 4 and then input into the steam injection pipe 2. The high-pressure steam is sucked into the steam injection pipe 2 from the gas in the negative suction pipe 1 under the action of the Bernoulli principle and mixed. Then the mixed gas enters the silencer and speed reduction component 6 to cool the gas, reduce the speed, and discharge it after the silencer effect. The steam regulating component ensures the working stability of the steam injection pipe 2 by adjusting the steam generation rate of the steam injection pipe 2.

[0046] The present invention utilizes the steam injection pipe 2 to suck the gas in the negative suction pipe 1, thereby realizing the vacuum at the input end of the negative suction pipe 1. The design utilizes the pressure and kinetic energy of steam to create the vacuum, and does not require external energy such as electrical energy and mechanical energy, thereby greatly reducing energy consumption. No additional heat or noise is generated during operation, and the structure is simple, and the operation is stable and reliable. Its efficacy can be adjusted by adjusting the structure 3, and the design of the steam generating component 4 ensures the stable supply of high-pressure steam to the steam injection pipe 2. At the same time, the design of the silencer and speed reduction component 6 can avoid the danger and noise caused by the high-speed, high-pressure, and high-temperature mixed gas being discharged from the steam injection pipe 2, thereby ensuring the safe operation of the steam injection pipe 2. The design of the steam regulating component ensures the steam injection of the steam conveying pipe 2, thereby avoiding the instability of the operation of the steam conveying pipe 2 caused by the lack of steam.

[0047] Example 2

[0048] On the basis of Example 1, the steam injection pipe 2 includes a suction chamber tube 21, the bottom flange of the suction chamber tube 21 is connected to the negative suction pipe 1, the right side of the suction chamber tube 21 is fixedly connected to the mixing tube 22, the output end of the mixing tube 22 is threadedly installed with a silencer and speed reduction component 6, the left side of the suction chamber tube 21 is bolted to the jet tube 23, the output end of the jet tube 23 is threadedly connected to the diffusion nozzle 24, the diffusion nozzle 24 and the mixing tube 22 correspond to each other, the bottom of the jet tube 23 is provided with a flange connected to the steam generating component 4, the left side of the jet tube 23 is penetrated and fixed with an adjustment structure 3, and the adjustment structure 3 slides relatively in the jet tube 23, the diffusion nozzle 24 and the mixing tube 22.

[0049] The adjustment structure 3 includes an adjustment core 31, the right end of the adjustment core 31 is threadedly connected to the end adjustment head 32, the right end of the adjustment core 31 is connected to the extension rod 33, the other end of the extension rod 33 is fixedly connected to the electric telescopic rod 34, the electric telescopic rod 34 is bolted to the side wall of the jet tube 23, and a sealing slide ring 35 is fixedly installed on the extension rod 33. The sealing slide ring 35 is slidably connected in the sealing tube 36, and the sealing tube 36 passes through and is fixed on the wall of the jet tube 23.

[0050] The working principle and beneficial effects of the above technical solution are as follows: before injecting high-pressure steam, the electric telescopic rod 34 is started to drive the extension rod 33 and the sealing sliding ring 35 to move, so that the adjustment core 31 and the terminal adjustment head 32 move relative to the diffusion nozzle 24 and the mixing tube 22 to achieve proportional adjustment of the opening of the diffusion nozzle 24 and the mixing tube 22, so that the efficacy of the steam injection tube 2 changes. After that, the steam generating component 4 injects high-pressure steam from the jet tube 23, and the high-pressure steam passes through the diffusion nozzle 24, so that the flow rate of the high-pressure steam is accelerated and the pressure is reduced, forming a low-pressure area in the suction cavity 21. The gas in the negative suction pipe 1 is sucked into the suction cavity 21 due to the pressure difference. Then, the high-pressure steam and the gas in the negative suction pipe 1 are mixed in the mixing tube 22, diffused and discharged, and enter the silencer and speed reduction component 6;

[0051] The present invention utilizes a diffusion nozzle 24 to increase the speed and reduce the pressure of high-pressure steam. This design can utilize the Bernoulli principle to relatively convert flow rate and pressure, has a relatively efficient vacuum suction efficiency, does not require external energy, is environmentally friendly and pollution-free, and cooperates with the design of the mixing tube 22 to evenly mix the high-pressure steam and the gas in the negative suction pipe 1. At the same time, the design of the adjustment core 31 and the end adjustment head 32 can adjust the efficacy of the steam injection tube 2. This design enables the steam injection tube 2 to achieve different effects as required, has high flexibility and adaptability, and by adjusting the efficacy, can improve energy utilization and avoid energy waste.

[0052] Example 3

[0053] On the basis of Example 1, the steam generating component 4 includes an air compressor 41, the output end of the air compressor 41 is flange-connected to the jet tube 23, the input end of the air compressor 41 is connected to a steam pipe 42, the other end of the steam pipe 42 is connected to a steam outlet 44 on a separation shell 43, a steam-water inlet 45 is provided on the other side of the separation shell 43, the steam-water inlet 45 is connected to the steam heat exchanger 5, a spiral flow channel 46 is fixed in the separation shell 43, a low-suction pipe 47 is provided in the center of the spiral flow channel 46, the low-suction pipe 47 is fixedly connected to the steam outlet 44, and a concentrated water outlet 48 is provided at the bottom of the separation shell 43.

[0054] The steam heat exchanger 5 includes a heat exchange shell 51, a water supply pipe 52 passes through and is fixed on the top of the heat exchange shell 51, a steam-water discharge pipe 53 passes through and is fixed on the side wall of the heat exchange shell 51, and the steam-water discharge pipe 53 is flange-connected to the steam-water inlet 45, a uniform distribution plate 54 is fixedly connected to the top of the heat exchange shell 51, a plurality of heating tubes 55 are arranged below the uniform distribution plate 54, both ends of the plurality of heating tubes 55 are fixedly connected to sealing tube clamps 56, and the sealing tube clamps 56 are fixedly connected to the heat exchange shell 51, an evaporation chamber 57 is arranged below the plurality of heating tubes 55, and a concentrated water outlet 58 is arranged at the bottom of the heat exchange shell 51.

[0055] The beneficial effects of the above technical solution are as follows: when producing high-pressure steam, water is injected into the water supply pipe 52 of the steam heat exchanger 5, and the water is evenly dispersed into a plurality of heating tubes 55 through the function of the uniform distribution plate 54. The water is heated when flowing through the heating tubes 55, and after the water falls into the evaporation chamber 57, the concentrated water accumulates at the bottom of the evaporation chamber 57, and the steam-water mixture enters the separation shell 43 from the steam-water discharge pipe 53. After the steam heat exchanger 5 has been working for a period of time, the air compressor 41 is started for extraction, and the low-intake pipe 47 in the separation shell 43 is discharged. Negative pressure suction is generated. Under the action of negative pressure, the steam-water mixture moves downward along the spiral flow channel 46 and enters the low-suction pipe 47. The water carried in the steam-water mixture adheres to the spiral flow channel 46 and falls into the bottom of the separation shell 43. The high-pressure steam then flows into the air compressor 41 through the steam pipe 42 and is pressurized. Then, it enters the steam injection pipe 2 from the jet pipe 23. The sealing pipe clamp 56 ensures that the middle part of the heating pipe 55 is isolated from the high-pressure steam. The concentrated water outlet 1 48 and the concentrated water outlet 2 58 are used to discharge the concentrated water.

[0056] The present invention utilizes a uniform distribution plate 54 to evenly distribute the water. This design enables the water to form a uniform liquid film along the heating tube 55, thereby improving the heating efficiency of the heating tube 55 on the water and preventing the water from being completely heated due to a fast falling speed when passing through the heating tube 55. The design of the spiral flow channel 46 enables the liquid in the steam-water mixture to be thrown out and adsorbed on the spiral flow channel 46 under the action of gravity and centrifugal force when the steam-water mixture descends under the action of negative pressure, thereby ensuring that the diameter of the water molecules in the high-pressure steam is small.

[0057] Example 4

[0058] On the basis of Example 1, the silencer and speed reduction component 6 includes a silencer shell 61, in which a partition 1 62 and a partition 2 63 are fixed in sequence, a first-level silencer pipe 64 is provided in the center of the silencer shell 61, and the first-level silencer pipe 64 is flange-connected to the mixing tube 22 through a front speed reduction cooling structure 7, the first-level silencer pipe 64 passes through and is fixed on the left side of the silencer shell 61, the partition 1 62 and the partition 2 63, a second-level silencer pipe 65 and a third-level silencer pipe 66 are respectively provided on the upper and lower sides of the first-level silencer pipe 64, the second-level silencer pipe 65 passes through and is fixed between the partition 1 62 and the partition 2 63, the third-level silencer pipe 66 passes through and is fixed on the right side of the silencer shell 61, the partition 1 62 and the partition 2 63, and a plurality of silencer holes 67 are provided on the first-level silencer pipe 64 between the partition 1 62 and the partition 2 63.

[0059] The front speed reduction cooling structure 7 includes a cooling pipe 71, and the two sides of the cooling pipe 71 are flange-connected to the mixing pipe 22 and the first-level silencer pipe 64 respectively. A cooling pipe 72 is arranged in the cooling pipe 71, and both ends of the cooling pipe 72 pass through and are fixed on the side wall of the cooling pipe 71. A condensate drain pipe 73 is fixed to the bottom of the cooling pipe 71, and a solenoid valve 74 is installed on the condensate drain pipe 73.

[0060] The beneficial effects of the above technical solution are as follows: after the mixed gas flowing out of the steam injection pipe 2 enters the cooling pipe 71, under the action of the cooling pipe 72, the temperature of the mixed gas undergoes heat exchange, thereby causing the water molecules in the mixed gas to condense to form condensed water and deposited in the cooling pipe 71, and then the mixed gas continues to advance into the first-level silencer pipe 64, and the gas enters the right chamber of the partition two 63 through the first-level silencer pipe 64, and then the mixed gas enters the left chamber of the partition one 62 from the second-level silencer pipe 65, and finally the mixed gas is discharged from the third-level silencer pipe 66, and when passing through the first-level silencer pipe 64, sound waves are discharged from the silencer hole 67, and the sound waves collide and offset each other in the chamber in the silencer shell 61. After the gas is reduced layer by layer in the chamber of the silencer shell 61, the sound waves and pressure are gradually reduced, and when it is finally discharged, the noise and pressure of the mixed gas are reduced to a controllable range;

[0061] The present invention utilizes a cooling pipe 71 to pre-treat the mixed gas. This design can reduce the temperature and water content in the mixed gas, and block the mixed gas to a certain extent, thereby preventing the mixed gas from carrying moisture into the silencer shell 61, causing the accumulation of condensed water and being unable to be discharged. At the same time, the design of the first-level silencer pipe 64, the second-level silencer pipe 65 and the third-level silencer pipe 66 enables the pressure and sound waves to pass through the three chambers and be reduced step by step, thereby ensuring the stable reduction of sound waves and pressure, and avoiding the impact of high pressure and noise on production and life. The design of the overall structure can avoid the high temperature, high pressure, and noise of the mixed gas from causing certain harm to the operators.

[0068] Pressure sensor 1: used to detect the pressure of steam in the jet tube 23, and disposed in the jet tube 23;

[0069] Pressure sensor 2: used to detect the pressure in the negative suction pipe 1, and arranged in the negative suction pipe 1;

[0070] The detection module is electrically connected to the data processing module, the control module is electrically connected to the data processing module and the execution module, and the control module controls the execution module to work based on the data results of the data processing module.

[0071] The control module controls the execution module based on the data results of the data processing module, including the following steps:

[0072] Step 1: Calculate the action coefficient F of the steam injection pipe 2 based on the detection values ​​of the flow sensor, heating power sensor, displacement sensor, temperature sensor, pressure sensor 1 and pressure sensor 2 c :

[0073] Among them, F c is the action coefficient of the steam injection pipe 2, k is the steam loss coefficient, μ is the heat conversion loss coefficient, P H is the detection value of the heating power sensor, c is the specific heat coefficient of water, T is the detection value of the temperature sensor, ρ is the density of water, P 2 is the detection value of pressure sensor 2, P 1 is the detection value of pressure sensor 1, R 1 is the inlet diameter of the diffusion nozzle 24, R 2 is the reduced diameter of the diffusion nozzle 24, X is the total displacement length of the electric telescopic rod 34, and L is the detection value of the displacement sensor;

[0074] Step 2: Data processing module comparison F c and F c0 , when F c ≤F c0 When the power variation coefficient P of the heating tube 55 is calculated, c , when F c >F c0 No processing is done when:

[0075] Where P c is the power variation coefficient of the heating tube 55, F c0 is the standard action coefficient of the steam injection pipe 2;

[0076] Step 3: The control module controls the execution module according to the power change coefficient P cThe power of the heating tube 55 is adjusted.

[0077] The beneficial effects of the above technical solution are as follows: when the steam injection pipe 2 is working, the generation and supply of steam have a significant effect on its effect. When the steam supply is insufficient, the working state of the steam injection pipe 2 will not meet the standard. Therefore, the working state of the steam injection pipe 2 is dynamically adjusted by monitoring the working state of the steam injection pipe 2 and the steam generation process.

[0078] The present invention utilizes a control module, a data processing module, a detection module and an execution module to monitor the steam injection pipe. This design can ensure the working state of the steam injection pipe 2 by adjusting the generation of steam, thereby ensuring the stable operation of the steam injector.
