Description

Technical Field

[0001] This utility model relates to the technical field of pickling equipment, and more specifically, to a pickling device for a tubular sodium hypochlorite generating equipment. Background Technology

[0002] Sodium hypochlorite generating equipment utilizes the reverse reaction principle of electrolysis of brine to produce sodium hypochlorite. During the long-term operation of sodium hypochlorite generating equipment, scale easily forms on the inner walls of its pipes, especially calcium and magnesium salt scale and corrosion products deposited in the electrolytic cell and connecting pipes, which seriously affect the operating efficiency and service life of the equipment.

[0003] Traditional pickling methods typically use liquid acid to circulate through pipes. However, due to uneven acid distribution and insufficient flow, the cleaning effect may be unsatisfactory in some areas, and it may even damage the equipment.

[0004] Therefore, in view of this, the existing structure is studied and improved to provide an acid washing device for tubular sodium hypochlorite generation equipment, in order to achieve a more practical purpose. Utility Model Content

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] This solution uses a circulating pump to inject acid solution, which can be used to acid-wash the electrode plates or related pipes inside the electrolytic cell. The acid solution is circulated, effectively ensuring the acid-washing effect. At the same time, microbubbles and fine plastic particles are pumped in during the acid-washing process.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figure 1 - Figure 4 A pickling device for a tubular sodium hypochlorite generating equipment includes an electrolytic cell 1, with several electrode plates 2 fixedly installed inside the electrolytic cell 1. An inlet pipe 3 is fixedly installed on the bottom side of the inlet end of the electrolytic cell 1. The bottom end of the inlet pipe 3 is a three-way interface. The first inlet of the three-way interface is connected to a horizontal injection pipe 301, and a one-way valve 302 is fixedly installed on the horizontal injection pipe 301. The second inlet of the three-way interface is connected to an L-shaped long conduit 303, and the opening of the L-shaped long conduit 303 is vertically upward. A first gas collecting bottle 304 is fixedly installed at the top end of the L-shaped long conduit 303, and an oblique injection pipe 305 is fixedly connected to the side near the top end of the L-shaped long conduit 303. The opening of the oblique injection pipe 305 is inclined upward.

[0034] An outlet pipe 4 is fixedly installed on the top side of the outlet end of the electrolytic cell 1. A second gas collecting bottle 401 is fixedly installed on the top end of the outlet pipe 4, and a drain pipe 402 is fixedly connected to the side near the top end of the outlet pipe 4. The opening of the drain pipe 402 is set at an angle downward.

[0035] This pickling device can pickle the electrode plates 2 or related pipes inside the electrolytic cell 1 by pumping in acid. By pumping in microbubbles and fine plastic particles, the pickling effect is greatly enhanced, thereby achieving effective cleaning of the electrode plates 2 or related pipes inside the electrolytic cell. The cleaning effect is quite ideal, and the cleaning process will not damage the equipment.

[0036] See Figure 4 In this diagram, A is the electrolytic cell, B is the circulating pump, C1 is the protective agent tank, C2 is the saturated brine tank, C3 is the softener tank, D1 and D2 are the corresponding hydrogen discharge pipes, E is the drug storage tank, F is the hydrogen discharge fan, H is the drug dosing pump, I is the softening tank, and J is the tap water.

[0037] See Figure 1 , Figure 4 Specifically, the horizontal injection pipe 301 is connected to a circulation pump 3011 via a flange. The liquid pumped into the circulation pump 3011 includes one of the following: a protective agent, saturated brine, or softened water.

[0038] A four-way pipe can be used to connect the horizontal injection pipe 301 to three circulating pumps 3011 at the same time. The three circulating pumps 3011 are respectively connected to the protective agent tank, the saturated brine tank and the softened water tank, which makes it easy to switch the type of liquid injected into the horizontal injection pipe 301 at any time.

[0039] See Figure 1 , Figure 4 Specifically, the horizontal injection pipe 301 is connected to an air pump via a flange, and the material pumped in by the air pump includes microbubbles or fine plastic particles.

[0040] The physical assistance of microbubbles and plastic particles significantly improves cleaning efficiency, allowing for more thorough contact with the acid solution, which in turn effectively enhances cleaning efficiency.

[0041] Specifically, the plastic granules are made of acid and alkali resistant polyethylene or polypropylene, with a particle size of 0.5 to 2 mm.

[0042] The fine plastic particles of this size flow with the acid and physically scrub the inner wall of the pipe, helping to remove stubborn dirt. Moreover, these fine plastic particles are not easy to accumulate or clog inside the pipe.

[0043] See Figure 1 , Figure 2 Specifically, the height of the inclined injection pipe 305 is higher than the height of the electrolytic cell 1.

[0044] Specifically, a drip irrigation hose 3051 is inserted into the opening of the oblique injection tube 305.

[0045] Because of the good height of the inclined injection tube 305, liquid can be easily injected by gravity dripping.

[0046] See Figure 1 , Figure 2 Specifically, the drain pipe 402 is connected to a filter tank 4021 via a flange, and a filter screen is installed inside the filter tank 4021.

[0047] The filter canister 4021 can collect discharged fine plastic particles, and with the filter screen, it can be easily reused.

[0048] Specifically, the electrolytic cell 1 is set with an inclination angle of 5°. During electrolysis, this is conducive to the emission of hydrogen. During emission, the inclination is conducive to the emission of particles. During pickling, it is adjusted to a horizontal state, which is conducive to the even impact of particles.

[0049] Working principle:

[0050] During electrolysis, one or more of the following are pumped into electrolytic cell 1: protective agent, saturated brine, and softened water. When cleaning electrolytic cell 1, a circulating pump 3011 is used to pump in the cleaning acid solution to complete a simple cleaning. Then, depending on the cleaning effect, an air pump is connected at the same time as pumping in the acid solution to pump in microbubbles or fine plastic particles. The microbubbles flow inside electrolytic cell 1 to agitate the acid solution flow, while the fine plastic particles can physically wash away the deposits attached to the electrode plates 2 and pipes, thereby effectively improving the cleaning effect.

[0051] During the cleaning process, the cleaning acid is discharged through the outlet pipe 4. At this time, the acid passes through the filter tank 4021 of the drain pipe 402, while the fine plastic particles are retained on the filter screen of the filter tank 4021, which is convenient for subsequent recycling and reuse.

[0052] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
