Embodiment 4

[0050] This embodiment provides a method for decalcifying grease. The decalcifying agent in Example 1 is selected, and the waste grease from kitchen waste is used as the grease sample to be decalcified, including the following steps:

[0051] (1) Preheat the oil sample and decalcifying agent to 120°C respectively;

[0052] (2) according to the mol ratio of calcium in the decalcifying agent and the grease sample is 2:1, and the weight of the water in the decalcifying agent is the ratio of 10% of the weight of the grease sample, preheated decalcifying agent and grease The sample is put into the first-level electric desalting tank and mixed at a speed of 3500r / min, and the electric field strength in the first-level electric desalting tank is adjusted to 3000V / cm, and the electric field residence time is 60min so that the calcium complex in the decalcifying agent and the oil sample Combined to form water-soluble substances; after that, the oil-water mixture obtained from the first...

Abstract

The invention relates to the technical field of grease decalcification, and provides a decalcification agent and a grease decalcification method. The decalcification agent provided by the invention isprepared from the following components in percentage by weight: 30%-60% of organic acid, 0.1%-1% of oleyl imidazoline quaternary ammonium salt, 0.1%-0.5% of a polyoxyethylene type nonionic surfactantand the balance of water. Through the synergistic effect of the components, the decalcification agent is endowed with good decalcification efficiency, and the corrosivity of the decalcification agentto a decalcification device is effectively reduced. The grease decalcification method provided by the invention comprises the following steps of: providing a grease sample to be decalcified and the decalcification agent; and mixing the grease sample with the decalcification agent, and then carrying out electric desalting treatment. The method realizes the purpose of effectively removing calcium in the grease, has good decalcification efficiency, is simple and convenient, is simple and flexible to operate, and can realize large-scale grease decalcification and reduce the grease decalcificationcost.

Description

technical field [0001] The application belongs to the technical field of decalcification of grease, and in particular relates to a decalcification agent and a method for decalcification of grease. Background technique [0002] With the rapid development of my country's social economy, people's quality of life has been greatly improved, and the amount of kitchen waste is also gradually increasing. At present, most kitchen waste has not been effectively recycled and utilized, causing serious adverse effects on the environment. At the same time, it has also caused serious resource waste and food safety hazards. The most serious problem is the recycling of waste oil in kitchen waste. Food waste contains a large amount of edible oil, which is commonly referred to as swill, and its main components are grain, vegetables, animal and vegetable oils, and animal spurs. Therefore, the harmless and resourceful treatment of food waste, especially the oil in food waste, has become the focu...
