At present, there is a need for degassing in the process of preparing fatty alcohol polyoxyethylene ether sulfate products. The fatty alcohol polyoxyethylene ether sulfate product solution prepared by the enterprise will contain 1,4-dioxane components. 1,4-dioxane is a toxic and harmful impurity. If its residual amount is too high, it will affect the quality and usability of the product. Degassing is the operation of removing 1,4-dioxane impurities. How to reduce the content of 1,4-dioxane as much as possible through equipment is an urgent need of the current enterprise, and this case is born from this. Utility Model Content

[0003] The purpose of the utility model is to solve the needs of the above-mentioned prior art and provide a degassing device. The device adopts a swing spraying method to refine the product solution and removes the volatile 1,4-dioxane components by vacuum suction to meet the degassing operation requirements of the product solution.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A degassing device comprises a tank body and a product liquid pipe, wherein the top of the tank body is connected to an exhaust pipe port, the bottom of the tank body is connected to a liquid outlet pipe port, the product liquid pipe is rotatably installed in the tank body, a plurality of spray nozzles are connected to the product liquid pipe, a swing power mechanism is installed outside the tank body, one end of the product liquid pipe is connected to a liquid inlet joint, and the other end of the product liquid pipe is transmission-connected to the swing power mechanism.

[0006] Furthermore, the spray nozzles are all installed upwards, and a plurality of the spray nozzles are arranged in a straight line along the length direction of the product liquid pipe.

[0007] Furthermore, a liquid collecting area is provided at the bottom inner side of the tank body, the liquid outlet is connected to the liquid collecting area, and the product liquid pipe is installed above the liquid collecting area.

[0008] The swing power mechanism includes a power box, a drive disk and a motor. The drive disk is rotatably installed in the power box. An incomplete gear is fixedly connected to the center of the drive disk. The output end of the motor is fixedly connected to the drive disk. A forward toothed belt is connected to the drive disk. A reverse toothed belt is connected to the incomplete gear. One end of the product liquid pipe extends into the power box and is fixedly connected to a gear with a tube.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 A degassing device shown in the figure comprises a tank body 1 and a product liquid pipe 2. The top of the tank body 1 is connected to an exhaust pipe port 11, and the exhaust pipe port 11 is connected to a vacuum suction device, whose function is to take away the gas in the tank body 1. During the degassing operation, 1,4-dioxane components will evaporate in the product solution, which are quickly taken away by the vacuum suction of the exhaust pipe port 11. The bottom of the tank body 1 is connected to a liquid outlet pipe port 12, and the liquid outlet pipe port 12 is used to output the product solution after the degassing operation. The product liquid pipe 2 is rotatably installed in the tank body 1, and a plurality of spray nozzles 21 are connected to the product liquid pipe 2. A swing power mechanism 3 is installed on the outside of the tank body 1. One end of the product liquid pipe 2 is connected to a liquid inlet joint 22, and the other end of the product liquid pipe 2 is transmission-connected to the swing power mechanism 3. The liquid inlet joint 22 The product delivery pipeline is connected to continuously deliver the product solution to the product liquid pipe 2, and then a solution spraying effect is formed through a spray nozzle 21 installed in the product liquid pipe 2. During the solution spraying process, the solution will naturally disperse to form droplets. In the droplet state, the 1,4-dioxane component therein is more easily volatilized, so that a better degassing effect can be formed (degassing refers to the operation of volatilizing the 1,4-dioxane component into gas and then removing it through vacuum suction). The swing power mechanism 3 can drive the product liquid pipe 2 to swing back and forth. When the product liquid pipe 2 swings, the spray liquid will not be fixed and concentrated at a certain position in the tank body 1. This design can make full use of the internal space of the tank body 1, so that the droplets are evenly dispersed, and it is also beneficial to improve the volatilization effect of the 1,4-dioxane component.

[0021] like Figure 1 and Figure 2 As shown, the spray nozzles 21 are all installed upwards, and several spray nozzles 21 are arranged in a straight line along the length direction of the product liquid pipe 2. A liquid collecting area 13 is provided at the bottom inner side of the tank body 1, and the liquid outlet 12 is connected to the liquid collecting area 13. The product liquid pipe 2 is installed above the liquid collecting area 13. If the spray nozzles 21 are installed upwards, an upward spray effect is formed, so that the droplets will first rise and then fall back to the liquid collecting area 13, forming an up-and-down movement process, which can double the movement stroke of the droplets, so that the droplets have sufficient time to evaporate the 1,4-dioxane component, and the degassing effect can be enhanced.

[0022] like Figure 2 and Figure 3 As shown, the swing power mechanism 3 includes a power box 31, a drive disc 32 and a motor 34. The drive disc 32 is rotatably installed in the power box 31. The center of the drive disc 32 is fixedly connected with an incomplete gear 33. The drive disc 32 can rotate together with the incomplete gear 33. The output end of the motor 34 is fixedly connected to the drive disc 32. The motor 34 can drive the drive disc 32 to partially rotate. The drive disc 32 is connected with a forward toothed belt 321, and the incomplete gear 33 is connected with a reverse toothed belt 331. One end of the product liquid pipe 2 extends into the power box 31 and is fixedly connected There is a tube gear 35, and both the forward toothed belt 321 and the reverse toothed belt 331 can mesh with the tube gear 35. The forward toothed belt 321 and the reverse toothed belt 331 need to mesh with the tube gear 35 alternately. When the forward toothed belt 321 meshes with the tube gear 35, the forward rotation of the product liquid pipe 2 can be formed. As the driving disk 32 rotates, it will switch to the reverse toothed belt 331 meshing with the tube gear 35, and the reverse rotation of the product liquid pipe 2 can be formed at this time. As the driving disk 32 continues to rotate, the product liquid pipe 2 can continuously switch between forward and reverse directions alternately to form a swinging spray effect.

[0023] like Figure 1 As shown, a diffuser net 4 is fixedly installed in the tank body 1, and the diffuser net 4 is installed above the product liquid pipe 2, that is to say, the diffuser net 4 blocks the upward path of the spray liquid column formed by the product liquid pipe 2, and the liquid column sprayed from the product liquid pipe 2 will collide with the diffuser net 4 to form more dense droplets. The dense droplets are conducive to the full volatilization of the 1,4-dioxane component and can further improve the degassing quality. The diffuser net 4 is a mesh structure and does not affect the passage of liquid or gas. Two downwardly concave humps 41 are formed on the diffuser net 4. The two humps 41 are symmetrically arranged and drooping. Firstly, when the product liquid pipe 2 rotates at a large angle, its liquid column can still effectively collide with the diffuser net 4 to form a better liquid dispersion effect. Secondly, the concave surface of the hump 41 has a guiding effect, so that the droplets fall to both sides as much as possible (there is the product liquid pipe 2 in the middle to block it, and it is not easy to directly enter the liquid collecting area 13 for collection).

[0024] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
