Abstract
Description
Technical Field
[0001] This invention relates to the field of demulsification of rolling oil, and in particular to a method for preparing pure natural demulsifying particles and its application. Background Technology
[0002] The basic components of rolling oil are: base lubricating oil, lubricating additives, emulsifiers, carbon removal additives, and corrosion inhibitors / pH corrosion inhibitors. The volume ratio of the oil phase to the water phase in the rolling oil emulsion used in this paper is 2:98. After mixing, the emulsion is uniformly mixed in an ultrasonic water bath to form a stable emulsion. This type of emulsion can be formed by directly adding the rolling oil to water at room temperature, with a stability index (ESI) above 0.6. The particle size of the prepared emulsion is between 1 and 1.5 micrometers, with a small portion reaching 5 micrometers. The stable emulsion has good annealing and cleaning properties and can be annealed directly without washing. Currently, the domestic methods for treating rolling oil emulsions after use are basically chemical methods and physical filtration to separate the oil phase and water phase for further processing.
[0003] Since the stability of rolling oil emulsion is affected by a large number of surfactants, and based on previous experiments, it has been known that the surfactants in the rolling oil are nonionic surfactants. In order to demulsify the rolling oil emulsion, the existing technology usually adopts the method of purchasing chemical reagents. However, chemical reagents often need to be purchased in large quantities, which is costly. In order to reduce costs and increase efficiency, a new type of demulsifying agent is needed to reduce the procurement costs of enterprises.
[0004] To address these issues, we propose a method for preparing and applying purely natural demulsifying granules. Summary of the Invention
[0005] The purpose of this invention is to provide a method for preparing pure natural demulsifying particles and its application method, in order to solve the problem mentioned in the background art that the chemical reagents used for demulsification are one of the products that need to be purchased in the demulsification environment, which leads to an increase in the demulsification cost for enterprises. The technical solution of this invention provides a solution that is significantly different from the existing technology, which addresses the problem that the existing technical solutions are too simplistic.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A method for preparing pure natural demulsifying granules includes the following steps: selecting dried lotus pods, dividing the lotus pods into sections, feeding the divided lotus pods into a pulverizer and crushing them into powder, screening the final powder through a sieve, taking the raw material of the powder that passes through the sieve to obtain lotus pod powder, and finally placing the lotus pod powder in an oven to dry it to obtain dried lotus pod powder, which is the demulsifying granules.
[0008] In a further embodiment, the pulverizer rotates at 25,000 r / min and uses a 200-mesh sieve.
[0009] In a further embodiment, the oven temperature is 45°C.
[0010] In a further embodiment, the lotus seedpod is a lotus seedpod top.
[0011] The present invention also provides a method for applying pure natural demulsifying particles, comprising the following steps: adding pure natural demulsifying particles to an oil-in-water type rolled oil emulsion, then mixing it in an ultrasonic water bath, and finally placing it in a dry and sealed environment to complete the demulsification.
[0012] In a further embodiment, the ultrasonic water bath is mixed for 10 minutes and placed in a dry, sealed environment for 12 hours.
[0013] In a further embodiment, the concentration of pure natural demulsifying particles in the oil-in-water rolling oil emulsion is 7 wt.%-10 wt.%.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. This method utilizes the amphiphilic composition and structure of pure natural dried lotus seed powder. Amphiphilicity means that pure natural dried lotus seed powder has both water-wetting ability (hydrophilic) and oil-wetting ability (hydrophobic). The hydrophobic structural part can interact with the lipophilic groups in nonionic surfactants and with the stable surfactants in the rolled oil emulsion, thereby disrupting the balance between the oil and water phases in the emulsion and achieving the demulsification effect. After demulsification, the properties of plant particles are not easily changed, and even with shaking, it is not easy to re-emulsify. Furthermore, the entire demulsification process is relatively short and the solution is stable.
[0016] After demulsification is complete, the aqueous phase can be filtered through a filter membrane to remove particles and obtain clean water. Compared with the demulsification schemes using strong acids and alkalis in factories, this scheme only requires filtration and does not require further treatment of strong acids and alkalis. The treatment process is also simpler and the environmental pollution is greatly reduced.
[0017] 2. Secondly, the demulsifier uses pure natural lotus pods as its material. After people consume the lotus seeds, the remaining lotus pods, which would otherwise be discarded, can be used as demulsifier materials, thus achieving the effect of recycling and turning waste into treasure. Moreover, it does not generate other industrial waste. Furthermore, the processing method of this solution is mainly crushing, which is simpler to prepare than traditional chemical reagent synthesis. It is one of the best demulsifiers currently available, demonstrating the effect of energy conservation and emission reduction.
[0018] 3. The solution uses dried lotus seed pods powder. The powder state can increase the contact area, and the dried lotus seed pods powder is more lipophilic than hydrophilic, which can interact with the lipophilic groups in the surfactant, change the tension between the surfactant and the water and oil phases, and thus achieve a better demulsification effect.
[0019] 4. Lotus pods, as a common agricultural waste, are often incinerated as agricultural waste or scrap, resulting in low manufacturing costs. This process transforms waste into valuable resources, contributing to carbon reduction. They also offer good food safety and high biocompatibility. Furthermore, when used in rolling oil emulsions, lotus pod granules maintain long-term oil-water phase separation after demulsification, demonstrating strong stability. As a pure, natural granule, lotus pod granules cause virtually no environmental damage and can be widely applied. In contrast, current factory demulsification methods using large amounts of strong acids and alkalis cause more environmental harm, further highlighting the energy-saving and emission-reduction goals of this solution.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1
[0026] Please see Figure 1 In this embodiment of the invention, a method for preparing pure natural demulsifying granules and its application method are described.
[0027] A method for preparing demulsifying granules involves selecting dried lotus seedpod pith, dividing the pith into sections, feeding the divided pith into a pulverizer, and crushing it into powder at a speed of 25,000 r / min. The final powder is then sieved through a 200-mesh sieve, and the raw material containing the powder passing through the sieve is collected to obtain lotus seedpod powder. Finally, the lotus seedpod powder is placed in an oven for drying to obtain dried lotus seedpod powder, which is the lotus seedpod pith granules.
[0028] A method for applying demulsifying particles includes the following steps: taking rolling oil and adding it to a test tube, stirring and dissolving it completely to obtain an emulsion, and then adding water to obtain an oil-in-water rolling oil emulsion;
[0029] The dried lotus seed pod inner pulp particles were added to the oil-in-water rolling oil emulsion to prepare five mixed solutions with lotus seed pod inner pulp particle concentrations of 0wt.%, 6wt.%, 7wt.%, 8wt.%, and 10wt.%. The solutions were then mixed in an ultrasonic water bath for 10 minutes and finally placed in a dry, sealed environment to stand for 12 hours and stored at room temperature to complete the demulsification.
[0030] Reference Figure 1The sample AF mass fractions were 0 wt.%, 6 wt.%, 7 wt.%, 8 wt.%, and 10 wt.%. Observation showed that the 0 wt.% and 6 wt.% lotus seed pod granule mixture prepared in Example 1 did not show demulsification, while the 7 wt% lotus seed pod granule mixture showed incomplete demulsification, and the supernatant was easily re-emulsified after slight shaking. The lotus seed pod granule mixture with mass fractions of 8 wt.% and 10 wt.% completely demulsified, and the supernatant was stable and did not emulsify after slight shaking. Example 2
[0031] Please see Figure 2 The difference from Example 1 is that the inner pulp of the lotus seedpod was replaced with the whole lotus seedpod, and all the lotus seedpod particles were obtained and made into five mixed solutions with concentrations of 0wt.%, 6wt.%, 7wt.%, 8wt.%, and 10wt.%.
[0032] Reference Figure 2 The sample AF mass fraction was 0 wt.%, 6 wt.%, 7 wt.%, 8 wt.%, and 10 wt.%. The lotus seed pods mixture with a mass fraction of 0 wt.% and 6 wt.% prepared in Example 2 did not show demulsification. The lotus seed pods mixture with a mass fraction of 7 wt.%, 8 wt.%, and 10 wt.% showed complete demulsification after 12 hours, and the supernatant was stable and not easily re-emulsified. Example 3
[0033] Please see Figure 3 The difference from Example 1 is that the inner pulp of the lotus seedpod is replaced with the top of the lotus seedpod to obtain lotus seedpod top particles, which are then prepared into five mixed solutions with concentrations of 0wt.%, 6wt.%, 7wt.%, 8wt.%, and 10wt.%.
[0034] Reference Figure 3 The sample AF mass fraction was 0wt.%, 6wt.%, 7wt.%, 8wt.%, and 10wt.%. The 0wt.% and 6wt.% lotus seed pod top granule mixture obtained in Example 3 did not show demulsification. The 7wt.%, 8wt.%, and 10wt.% lotus seed pod top granule mixtures all completed demulsification after standing for 12 hours, and the supernatant was stable.
[0035] Conclusion: When the concentration of the three types of lotus seed pods reached 8 wt%, the mixture of the three types of lotus seed pods was completely demulsified and the demulsification effect was stable. This is because dried lotus seed pod powder is amphiphilic, while the rolling oil emulsion stabilizer is the nonionic surfactant. The amphiphilic nature of dried lotus seed pod powder allows it to interact with the lipophilic groups in the nonionic surfactant and the surfactant in the rolling oil emulsion stabilizer, thereby disrupting the balance between the oil and water phases in the emulsion.
