After the equilibrium partial pressure is formed on the water surface, only a small amount of sulfur trioxide dissolves in water during cooling, and the absorption rate of sulfur trioxide is low, affecting normal production. It is impossible to use other materials to replace the acid water configuration. Utility Model Content

[0024] In this embodiment, by providing a tee 2, a pipeline full-view mirror 1 and a steel-clad pipe Ⅰ7 connected in sequence, and the steel-clad pipe Ⅰ7 extends into the container 9, and a layer pipe 3 is provided to pass through the upper hole of the tee 2 and extend into the pipeline full-view mirror 1, sulfur trioxide gas can be injected into the water contained in the container 9 through the layer pipe 3 through the pipeline full-view mirror 1 and the steel-clad pipe Ⅰ7 in sequence, and then the third pipe hole 2-1 of the tee 2 is connected to the diaphragm pump 6 and the steel-clad pipe Ⅱ8 in sequence through the pipeline, and the steel-clad pipe Ⅱ8 also extends into the container 9. When working, the diaphragm pump 6 draws water from the container 9 along the steel-clad pipe Ⅱ8, injects it into the tee 2, and then flows out from the lower hole of the tee 2 into the pipeline The pipeline full-view mirror 1 forms a water flow circulation. A grid plate 5 is set in the pipeline full-view mirror 1. The water flows through the grid plate 5 and is divided into a rain-like shape, covering the upper part of the sulfur trioxide gas, thereby increasing the contact area between the sulfur trioxide gas and the water. The sulfur trioxide gas and the rain-like water are fully in contact in the pipeline full-view mirror 1 to dissipate heat. The pipeline full-view mirror 1 can observe the reaction state of water and sulfur trioxide gas. The gaseous and liquid substances in the pipeline full-view mirror 1 flow through the steel pipe II 8 and flow into the container 9 together, where they are absorbed again and cooled at the same time, thereby improving the absorption effect of water on sulfur trioxide gas and improving the absorption rate of the reaction between sulfur trioxide and water.

[0025] Specifically, sulfur trioxide gas can be injected into the layer tube 3 through nitrogen pressure. Nitrogen pressure can make the gaseous and liquid substances in the pipeline full-view mirror 1 flow through the steel pipe II 8 and flow into the container 9 under pressure together, thereby increasing the flow rate; the tee 2 can be an unequal diameter tee, and the diameter of the pipeline connecting the upper hole and the lower hole is larger than the diameter of the third pipe hole 2-1, so that the flow rate of sulfur trioxide gas is greater than the flow rate of water, so that every portion of water can contact with sulfur trioxide gas, thereby increasing the absorption rate; the pipeline full-view mirror 1 can be made of high borosilicate glass material, which has thermal stability and acid resistance and is not affected by the reaction between sulfur trioxide gas and water; the layer tube 3, the grid plate 5, the steel pipe I7, and the steel pipe II8 can all be made of tetrafluoroethylene material, which has strong corrosion resistance and high temperature resistance, and will not be damaged by the reaction between water and sulfur trioxide gas, thereby increasing the service life of the device.

[0026] Optionally, the layer pipe 3 is connected to the upper hole of the tee 2 by using a flange whose flange width is greater than that of the tee 2 .

[0027] In this embodiment, a flange is provided between the layer pipe 3 and the upper hole of the tee 2, and the flange width is greater than the flange flange width of the tee 2, so that the layer pipe 3 and the tee 2 are conveniently connected together in a sealed manner, thereby improving the stability and sealing of the connection structure.

[0028] Optionally, the layer tube 3 includes an inner layer, an intermediate layer and an outer layer arranged in an annular sleeve, the intermediate layer is a seamless steel tube, and the inner layer and the outer layer both have tetrafluoroethylene tubes.

[0030] Optionally, the layer tube 3 extends into the pipeline full-view mirror at a depth of 160% to 80%.

[0031] In this embodiment, by extending the layer tube 3 to 60% to 80% of the depth of the pipeline full-view mirror 1, the absorption rate is better, and the optimal position is two-thirds of the pipeline full-view mirror 1. The fusion effect of sulfur trioxide and water can reach 80% of the absorption rate of sulfur trioxide by water per hour.

[0032] Optionally, the diameter of the pipeline full-view mirror 1 is between 88 mm and 92 mm, and the length is between 195 mm and 205 mm.

[0033] In this embodiment, by setting the pipe full-view mirror 1 to have a diameter between 88 mm and 92 mm and a length between 195 mm and 205 mm, the absorption rate is better, the optimal diameter is 90 mm, and the optimal length is 200 mm. The sulfur trioxide gas can be fully in contact with the rain-like water in the pipe full-view mirror 1, dissipating heat and improving the absorption rate.

[0034] Alternatively, if Figure 1 As shown, the steel-clad pipe I7 and the steel-clad pipe II8 are both pipes with curvature, and both extend downward close to the inner wall of the container 9.

[0035] In this embodiment, by setting the steel-clad pipe I7 and the steel-clad pipe II8 as tubes with curvature extending toward the lower end of the container 9 close to the inner wall of the container 9, and respectively arranging them on both sides of the container 9, the steel-clad pipe II8 absorbs from the bottom of the container 9, and the steel-clad pipe I7 injects the gaseous and liquid substances in the pipeline full-view mirror 1 into the bottom of the container 9, which is convenient for the liquid circulation in the container 9, so that the water in the container 9 is in contact with the sulfur trioxide gas and reacts, thereby improving the absorption rate.

[0036] Optionally, the pipeline includes a tetrafluoroethylene-lined pipeline, and both ends of the tetrafluoroethylene-lined pipeline are respectively connected to the third pipe hole 2-1 and the diaphragm pump 6.

[0038] Optionally, the gap between the layer tube 3 and the upper hole of the tee 2 is sealed by a seal.

[0039] In this embodiment, the layer tube 3 and the tee 2 are sealed and connected by a seal to prevent external gas from entering the device to affect the reaction between water and sulfur trioxide gas, and also to prevent water leakage, thereby improving the overall sealing of the device. The seal can be a sealing ring.

[0040] Alternatively, if Figure 1 As shown, the sulfur trioxide and water absorption and dissolution device also includes a container flange 4, one end of the container flange 4 is connected to the pipeline full-view mirror 1, and the other end is connected to the steel-clad pipe II 8, and the container flange 4 is placed above the container 9.

[0041] In this embodiment, by connecting the pipeline full-view mirror 1 and the steel-clad pipe II 8 through the container flange 4, the stability of the connection between the pipeline full-view mirror 1 and the steel-clad pipe II 8 is improved, and the overall structural strength of the device is improved. The container flange 4 is located above the container 9 and does not contact the water in the container 9, preventing the water from affecting the sealing of the container flange 4.

[0042] Alternatively, if Figure 1 As shown, the pipeline full-view mirror 1 extends in the vertical direction.

[0043] In this embodiment, by setting the pipeline full-view mirror 1 to extend in the vertical direction, the sulfur trioxide gas and the water flow can flow in a straight line in the pipeline full-view mirror 1. The straight-line flow has the fastest flow speed, thereby improving the absorption speed.
