Description

Technical Field

[0001] This utility model belongs to the technical field of spraying devices, and particularly relates to an organic acid electrolysis spraying device. Background Technology

[0002] With the rapid development of the chemical industry, the demand for organic acids is increasing. Among them, succinic acid (butanoic acid) is an important organic acid with wide applications in food, medicine, agriculture, and chemical industries.

[0003] The electrolytic preparation of succinic acid is typically carried out in a specific electrolytic cell, producing the target product by electrolyzing a substrate solution containing a certain concentration. However, this process is not entirely without side effects—a series of byproduct gases are generated during electrolysis.

[0004] Currently, industrial applications often employ spray systems to purify electrolytic waste gas. The basic principle is to atomize the absorbent liquid through nozzles, allowing it to fully contact the waste gas and thus absorb, neutralize, or condense harmful components. However, because the spray liquid often contains impurities or particulate matter generated during the electrolytic reaction, the ordinary spray heads used in traditional spray systems are prone to clogging. Utility Model Content

[0005] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0006] This utility model provides an organic acid electrolysis spraying device, comprising:

[0007] Processing box;

[0008] A spray assembly is located at the top inside the treatment tank. The spray assembly includes a spray pipe and several spray heads connected to the spray pipe. Each spray head includes a housing with multiple water outlet holes spaced circumferentially through it. A fixing frame is also provided on the outer wall of the housing corresponding to each water outlet hole. A plug is elastically provided on the fixing frame. In its natural state, the plug blocks the corresponding water outlet hole. In the spraying state, the plug is pushed away from the water outlet hole by an external force.

[0009] As a preferred embodiment of the above technical solution, one end of the plug is provided with an insertion rod, the fixing frame is provided with a slot for inserting the insertion rod, and a spring is also provided in the slot to connect the inner wall of the slot and the insertion rod.

[0010] As a preferred embodiment of the above technical solution, it also includes guide plates, wherein multiple guide plates are disposed on the inner wall of the processing box, and the multiple guide plates are staggered along the longitudinal direction.

[0011] As a preferred embodiment of the above technical solution, the plurality of guide plates are at least sequentially arranged as guide plate one, guide plate two, and guide plate three, and each of the guide plate one, guide plate two, and guide plate three is provided with a through hole, wherein the diameter of the through hole on guide plate one is smaller than the diameter of the through hole on guide plate three.

[0012] As a preferred embodiment of the above technical solution, the spray assembly further includes a water tank and a water supply pipe, wherein the water supply pipe connects the water tank and the spray pipe.

[0013] As a preferred embodiment of the above technical solution, an air inlet pipe is connected to the lower end of the processing box, and an exhaust pipe is connected to the upper end of the processing box.

[0014] As a preferred embodiment of the above technical solution, an electrolytic cell is also included, wherein the air inlet pipe of the processing box is connected to the electrolytic cell.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) The present invention has a spray head with a flexible movable plug structure at each water outlet of the housing. The water outlet is automatically closed in the non-spraying state to prevent impurities from entering and causing blockage. The plug is inserted into the slot of the fixed frame through the plug rod and connected by the spring. The water pressure drives it to open and automatically reset after stopping. It has good anti-blocking performance. In addition, the elastic plug structure seals the water outlet in the natural state, which can also reduce the intrusion of external air and reduce the oxidation and rust of metal parts.

[0017] (2) This utility model uses multiple guide plates arranged longitudinally at staggered intervals to make the exhaust gas form a “Z” shaped flow path in the treatment box, which prolongs the residence time of the exhaust gas. In addition, the diameter of the through holes on the guide plates gradually increases from bottom to top, which effectively controls the change of airflow speed and achieves step-by-step deceleration and enhanced disturbance.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example

[0026] like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is a front view of the spray device in the embodiment; Figure 2 The diagram shown is a cross-sectional view of the spray head in the embodiment;

[0027] This device includes:

[0028] The processing box 10 has an air inlet pipe 11 connected to its lower end and an exhaust pipe 12 connected to its upper end.

[0029] Guide plates 20, multiple guide plates 20 are disposed on the inner wall of the processing box 10, and the multiple guide plates 20 are staggered along the longitudinal direction;

[0030] The spray assembly is located at the top of the treatment box 10. The spray assembly includes a spray pipe 31 and several spray heads 32 connected to the spray pipe 31. Each spray head 32 includes a housing 321. Multiple water outlet holes 322 are provided circumferentially through the housing 321. A fixing frame 323 is also provided on the outer wall of the housing 321 corresponding to the position of each water outlet hole 322. A plug 324 is elastically provided on the fixing frame 323. In its natural state, the plug 324 blocks the corresponding water outlet hole 322. In the spraying state, the plug 324 is pushed away from the water outlet hole 322 by external force.

[0031] The treatment box 10 serves as the main container for waste gas treatment. The inlet pipe 11 is used to introduce the waste gas generated by succinic acid electrolysis into the treatment box 10, and the exhaust pipe 12 is used to discharge the purified gas after spray treatment.

[0032] Multiple guide plates 20 can change the flow path of exhaust gas in the treatment box 10, prolong the residence time of exhaust gas in the treatment box 10, increase the contact area and time between exhaust gas and spray liquid, and improve purification efficiency.

[0033] When water flows through the housing 321 of the spray head 32, it sprays water out through the outlet hole 322 to achieve spraying. The plug 324 blocks the outlet hole 322 in its natural state. In the spraying state, it is pushed by the water pressure to automatically open the outlet hole 322 to achieve uniform spraying. The structure of the plug 324 can prevent particles or impurities from entering the housing 321 and causing blockage. In addition, when not in operation, it seals the inside of the spray head 32, which can also slow down the oxidation and corrosion process of metal parts.

[0034] It also includes an electrolytic cell 1, and the air inlet pipe 11 of the processing box 10 is connected to the electrolytic cell 1.

[0035] Electrolytic cell 1 performs succinic acid electrolysis reaction, generating the target product while also producing some waste gas. Inlet pipe 11 guides the waste gas generated during the succinic acid electrolysis process into treatment box 10 for subsequent treatment.

[0036] It also includes a water tank 33 and a water supply pipe 34, with the water supply pipe 34 connecting the water tank 33 and the spray pipe 31.

[0037] Specifically, a pump body is installed inside the water tank 33. The water tank 33 is used to store spray liquid, such as clean water, alkaline solution or other absorbent liquid. The water pipe 34 serves as the transmission channel for the spray liquid from the water tank 33 to the spray pipe 31. The pump body provides the power required for the delivery of the spray liquid, ensuring that the spray head 32 obtains sufficient pressure when working, so that the plug 324 can open smoothly and achieve effective spraying.

[0038] like Figure 3 As shown, Figure 3 The diagram shown is a structural schematic of the fit between the plug and the fixing frame in the embodiment;

[0039] One end of the plug body 324 is provided with a plug rod 3241, and the fixing frame 323 is provided with a slot 3231 for inserting the plug rod 3241. A spring 3232 is also provided in the slot 3231 to connect the inner wall of the slot 3231 and the plug rod 3241.

[0040] The insertion rod 3241 slides into the slot 3231. The spring 3232 provides elastic support for the insertion rod 3241 and plays a role in resetting, so that the plug 324 can move flexibly in the horizontal direction under water pressure.

[0041] like Figure 4 , Figure 5 As shown, Figure 4 The diagram shown is a top view of guide plate one in the embodiment. Figure 5 The diagram shown is a top view of guide plate three in the embodiment;

[0042] Multiple guide plates 20 are arranged in order from bottom to top as guide plate one, guide plate two, and guide plate three. Guide plate one, guide plate two, and guide plate three are all provided with through holes 21. The diameter of the through hole 21 on guide plate one is smaller than that of the through hole 21 on guide plate three.

[0043] The guide plates 20 are arranged at intervals along the longitudinal direction to form a gas flow path similar to a "Z" or a snake. The purpose is to prolong the residence time of the exhaust gas in the treatment box 10 and enhance the gas-liquid contact effect. After the exhaust gas enters the treatment box 10 from the electrolytic cell 1, it first passes through the guide plate 1 with a smaller through hole 21. At this time, the airflow is subject to greater resistance and the speed is initially slowed down. As it rises, the airflow passes through the guide plate 2 and the guide plate 3. The through hole 21 gradually becomes larger and the airflow resistance decreases. The overall trend is "gradual acceleration and release". This design helps to prevent the airflow from rushing out of the exhaust pipe 12 too quickly, while ensuring sufficient gas-liquid contact and improving the absorption / neutralization efficiency.

[0044] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
