Description

Technical Field

[0001] This utility model relates to reaction vessels, specifically a steam ejector for reaction vessels. Background Technology

[0002] Currently, silica reaction vessels and heating vessels are generally becoming larger and taller (typically with a volume of 50-80 cubic meters and a height of >6 meters). Most reaction vessels use steam heating, with a simple heating pipe design. The steam pipe is directly introduced into the bottom of the reaction vessel through a bottom-entry method. After the steam valve is opened, the saturated steam directly exchanges heat with the liquid inside the vessel.

[0003] Current steam heating methods have the following drawbacks:

[0004] Heating causes high gas pressure, which can easily lead to gas explosions, damage to the tank, and weld cracks that can cause liquid leaks.

[0005] When the medium inside the tank undergoes physical changes (concentration, composition), the liquefaction thermal conductivity changes, and heating occurs through heat conduction and diffusion between liquids, resulting in a slow heating rate.

[0006] The exchange of heat between steam and liquid medium inside the tank takes time, resulting in a large temperature difference between the upper and lower liquid layers inside the tank, making temperature control difficult. Utility Model Content

[0007] To address the shortcomings of the prior art, this invention provides a steam ejector for a reaction vessel. This invention combines a steam injection point with a baffle plate, which is designed as a long, hollow column. Multiple nozzles are installed on the baffle plate, allowing steam to be injected into the vessel from multiple angles and heights for heating. This makes it easy to control the temperature, provides a fast heat exchange rate, and reduces the risk of gas explosions.

[0008] To achieve the above technical objectives, the present invention adopts the following technical solution: a steam ejector for a reaction vessel, comprising at least two baffles disposed on the inner wall of the reaction vessel, the baffles being hollow, and multiple nozzles being installed on the baffles, the multiple nozzles being of different heights, the steam pipes of the nozzles passing through the inside of the baffles and extending through the reaction vessel to the outside of the reaction vessel; the at least two baffles being of the same height, and the multiple nozzles located on different baffles being staggered in height.

[0009] The baffle plate is welded from six stainless steel plates, and one side is welded to the inner wall of the reaction vessel.

[0010] The at least two baffles are arranged symmetrically.

[0011] The plurality of nozzles are installed in the holes of the baffle plate, the nozzles are facing the center of the reaction vessel, and an outer baffle and an inner baffle are fixed on the nozzles. The outer baffle is fixed to the outer wall of the baffle plate, and the inner baffle is fixed to the inner wall of the baffle plate.

[0012] The baffle plate is equipped with a mounting bracket to support the steam pipe.

[0013] The mounting bracket includes a fixing plate and a fixing arc plate. Both ends of the fixing plate are fixed with welding plates. The welding plates are welded to the inner top and inner bottom of the baffle plate. The fixing arc plate is provided with multiple C-grooves for supporting the steam pipe. Connecting plates are provided between adjacent C-grooves and at the outer end of the outermost C-grooves. Bolts are provided on the connecting plates. The fixing plate has multiple bolt holes, and the bolts are fastened to the bolt holes.

[0014] The steam pipe is also fixed with a side baffle ring, which is fixed to the outer wall of the reaction vessel.

[0015] In summary, this utility model achieves the following technical effects:

[0016] This utility model combines a steam injection point with a baffle plate. The baffle plate is designed as a long, hollow column and is equipped with multiple nozzles, so that steam can be injected into the tank from multiple angles and heights for heating.

[0017] The steam injection points on the multiple baffles of this invention are staggered at different heights, so that the medium at each level inside the tank can exchange heat, and prevent liquid tumbling caused by nozzles on two baffles being at the same height. Attached Figure Description

[0027] Example:

[0028] Figure 1It is a steam ejector for a reaction vessel, comprising at least two baffles 2 disposed on the inner wall of a reaction vessel 1. The baffles 2 are hollow and are equipped with a plurality of nozzles 3 at different heights. The steam pipes 4 of the nozzles 3 pass through the interior of the baffles 2 and extend through the reaction vessel 1 to the exterior of the reaction vessel 1. The at least two baffles 2 are at the same height, and the plurality of nozzles 3 located on different baffles 2 are arranged at staggered heights.

[0029] This invention combines steam injection points with baffles. The baffles are designed as long, hollow columns with multiple nozzles, allowing steam to be injected into the tank from multiple angles and heights for heating. The steam injection points on the multiple baffles are staggered in height, ensuring heat exchange between all layers of the medium within the tank and preventing liquid turbulence caused by nozzles at the same height on two baffles.

[0030] The baffle plate 2 is welded from six stainless steel plates, with one side welded to the inner wall of the reaction vessel 1. In this embodiment, the baffle plate is a hollow column of 10cm*5cm, with the hollow interior used to install nozzles and steam pipes.

[0031] At least two baffles 2 are symmetrically arranged. In another embodiment, there can be three baffles, symmetrically arranged, with a 120° angle between them, so that the three sets of nozzles spray at three angles, thereby accelerating heat exchange.

[0032] Figure 2 This is a schematic diagram of the internal cross-section of the baffle plate. The plurality of nozzles 3 are installed in the holes opened in the baffle plate 2. The nozzles 3 face the center of the reaction vessel 1. An outer baffle 6 and an inner baffle 7 are fixed on the nozzles 3. The outer baffle 6 is fixed to the outer wall of the baffle plate 2, and the inner baffle 7 is fixed to the inner wall of the baffle plate 2.

[0033] The invention's outer baffle 6 and inner baffle 7 ensure stable nozzle installation, preventing swaying as the liquid flows and resulting in more stable jet spraying.

[0034] The baffle plate 2 is equipped with a mounting bracket 5 for supporting the steam pipe 4.

[0035] Figure 3 This is a schematic diagram of the mounting bracket. Specifically, the mounting bracket 5 includes a fixing plate 51 and a fixing arc plate 52. Both ends of the fixing plate 51 are fixed with welding plates 55. The welding plates 55 are welded to the inner top and inner bottom of the baffle plate 2. The fixing arc plate 52 is provided with multiple C-grooves for supporting the steam pipe 4. Connecting plates 53 are provided between adjacent C-grooves and at the outer end of the outermost C-grooves. Bolts are provided on the connecting plates 53. The fixing plate 51 has multiple bolt holes 54, and the bolts are fastened to the bolt holes 54.

[0036] This invention features an installation bracket 5 inside the baffle plate to support the steam pipe and prevent it from sag due to gravity, which could cause it to break off from the nozzle. The support part is an arc-shaped C-groove, which allows the steam pipe to sag slightly. The sag is supported by the C-groove, which prevents the steam pipe from breaking and allows the steam pipe inside the baffle plate to be longer, providing space for thermal expansion and contraction.

[0037] The steam pipe 4 is also fixed with a side baffle ring 8, which is fixed to the outer wall of the reaction vessel 1 to prevent the steam pipe 4 from shrinking inward.

[0038] The steam pipe is also equipped with a check valve 9 to prevent liquid backflow, and the steam pipe is connected to the main pipe 10.

[0039] Nozzle 3 is a stainless steel high-pressure steam nozzle.

[0040] Since the medium inside the tank needs to be stirred at medium / high speed, this utility model has 2-3 baffles inside the tank. The baffles are modified to be used as steam heating ejectors. The baffles are installed in the tank body, covering 70% of the height of the cylindrical liquid surface. The designed steam ejector can spray steam within 70% of the height of the cylindrical liquid surface in the tank.

[0041] Steam is injected through multiple injection points at different heights within the baffle plate to heat the medium, which can reduce the gas explosion phenomenon caused by excessive airflow.

[0042] Steam is injected into the medium through multiple high-altitude injection points to heat it, which can accelerate heat exchange between the media and improve heating efficiency.

[0043] Steam is injected through multiple injection points at various heights within the baffle plate to heat the medium, which can reduce the temperature difference between different heights within the tank, facilitating reaction control and heating control, and effectively saving energy.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
