Of course, this does not mean that the present invention is limited thereto, and even if a scheme is adopted in which the central axes of the steam injection cone 2, the noise reduction cone 3, the outer conical ring 13, the inner conical ring 14, the outer circular ring 15, and the inner circular ring 16 are not collinear with the central axis of the liquid passing cylinder 1 (for example, slightly deviated from the central axis of the liquid passing cylinder 1), it will fall within the scope of the present invention, which preferentially protects the collinear scheme, but also appropriately widens the scope of protection to protect some modifications.
When the jet steam jet heater is used for heating, for example, water flow enters the liquid passing cylinder 1 from the liquid inlet 4 and is reasonably distributed in the first annular liquid passing channel 10 through the fluid diversion distribution device 18. Since it is clear that there is a blocking of the steam inlet pipe 12 in the direction of flow, a fluid diversion distribution device 5 is needed to distribute the flow reasonably, ensuring that the flow around the intermediate transition flow channel 17 is uniformly distributed.
The water flow continues to advance, and is sprayed in an accelerating way on the whole in the middle transition flow passage 17 through the first annular liquid passing channel 3, and the middle transition flow passage 17 is actually a circular nozzle, is narrow at the same time, has extremely high water flow speed, is particularly favorable for eliminating vibration and is also helpful for controlling noise.
Emphasis and repetition are:
the annular water nozzle realizes the annular jet flow of water. The invention relates to a domestic and foreign steam direct heating device, which initially designs a circular water nozzle.
This high-speed injected water flow passes slowly with a deceleration inside the second annular flow channel 11, in the course of which it is directly heated by the steam injected at high speed from inside the steam injection cone 2. The water flowing out of the second annular liquid passage 11 is driven by the high-speed steam jet of the steam jet outlet 7 to flow forwards out of the device from the liquid outlet 5.
The steam connecting pipe 12, the steam injection conical cylinder 2, the outer conical ring 13 and the injection circular plate 8 which are in the shape of the elbow form together form a steam inner cavity with a brand new structure, and compared with other structures, the steam inner cavity has the smallest volume and is particularly favorable for eliminating water hammer and vibration. Because the inner cavity of the steam is extremely small, the system sloshing caused by steam fluctuation can be reduced, and further water hammer and vibration in the direct heating process of the steam are reduced.
Although the diameter of the steam jet outlet 7 is a little larger, the steam flow jetted from the steam jet outlet 7 is extremely small, and the influence on the system noise is extremely small and has no influence.
The main body of the present invention is located at the center of the water flow, and the diameter of the steam jet outlet 7 is relatively large, so that the present invention does not cause blockage. Since the steam pressure is higher than the liquid pressure, there is a pressure difference, and when the device is in operation, the material cannot enter the inside of the steam injection cone 2, including the inside of the steam cavity, and at this time, there is no clogging problem. Before the steam is not added into the device, the steam enters the interior of the steam jet conical cylinder 2 and comprises materials entering the interior of a steam inner cavity, after the steam is added, the steam pressure is higher than the pressure of liquid, and meanwhile, a specially designed steam jet outlet 7 is arranged, and the materials can be jetted out from the steam jet outlet 7 under the pressure of the steam because the diameter ratio of a hole is larger, so that the blockage can be avoided.
The invention originally adopts the basic structure for the first time, can directly heat the steam of various liquids (including water, sewage, viscous fluid, liquid containing suspended matters or precipitated particles), and can also eliminate vibration, blockage and noise, which is a great breakthrough in the field of direct steam heating.
The steam injection cone includes the special case of a cone angle of 0 degrees.
It is clear that the completely new foundation structure is above, because its main part is located in the center of the water flow, which flows from its periphery, and the suspended matter can pass through the upper part of the foundation structure. The precipitable particles can also pass through the lower part of this completely new infrastructure. The first one achieves direct heating of the steam containing the suspended matter, or containing the precipitable particles.
It is clear that even viscous fluids, for example; kitchen waste, ore pulp, syrup, papermaking black water, paper pulp and the like can smoothly pass through the periphery of the main body part of the basic structure. Because the steam injection through holes can be different in diameter as required, the problem of clogging is solved. And because the steam jet outlet is relatively large, large particles entering the steam jet conical cylinder 2 can be washed away by the force of steam.
The novel basic structure can comprehensively realize the direct heating of the steam of various liquids.
Most of the steam passes through the steam jet through holes 6 with smaller diameter and is obliquely jetted to the liquid flowing around at high speed, so the noise is low. The steam injection conical barrel adopts a conical barrel shape, which is beneficial to controlling noise.
In addition, the basic structure, especially the steam access pipe 12 in the shape of an elbow, the steam injection conical cylinder 2, the outer conical ring 13 and the injection circular plate 8 form a steam inner cavity together. Because the steam cavity has the smallest volume compared with other structures, the steam cavity is particularly beneficial to eliminating water hammer and vibration. Because the steam inner cavity is small, the system sloshing caused by steam fluctuation can be reduced, and further water hammer and vibration in the direct heating process of steam are reduced.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations fall within the scope defined by the appended claims.
