Problems solved by technology

At present, there are the following deficiencies in the treatment process of plant waste oil. First, there is a lack of pretreatment of waste oil. Plant waste oil contains more impurities and pigments. Direct processing and use will affect the normal operation of the equipment and cause great damage to the equipment.
Second, the purification methods of oleic acid include freezing pressing method, surfactant method, etc. The freezing pressing method has low equipment requirements, but has high labor intensity, low efficiency, and cannot be operated continuously; the surfactant method is also called the emulsification method. More waste water, lower separation purity

Abstract

The present invention relates to the field of production devices, in particular to a process equipment for producing oleic acid from plant waste oil, including a pretreatment device, a cracking device and a purification device; the pretreatment device includes a pickling tank and a settling reactor, and the acid The top of the washing tank is provided with a first feed port, and the side is provided with a waste outlet; the settling reactor includes a reactor body and a liquid storage tank, and a second feed port is provided at the upper end of the reactor body. The invention solves the problems that the existing process equipment for producing oleic acid lacks pretreatment of waste oil, high labor intensity, low efficiency and cannot be continuously operated. The invention discloses a whole set of equipment for producing oleic acid by using plant waste oil and a production process for oleic acid by using the equipment. The equipment mainly includes a pretreatment device, a cracking device and a purification device. So that waste oil can be purified to the greatest extent.

Description

technical field [0001] The invention relates to the field of production devices, in particular to a process equipment for producing oleic acid from plant waste oil. Background technique [0002] Waste vegetable oil refers to a series of oil waste that loses edible value produced by human beings in the process of eating natural vegetable oil and oil deep processing. The waste oil produced in the catering process is also called catering waste oil. The fatty acid composition of waste catering oil and fresh edible oil is basically the same, mainly containing oleic acid and linoleic acid. Oily soapstock produced during food processing is a by-product produced when refining various vegetable oils. The amount produced is 2% to 3% of the total oil production. Its composition and properties are determined by the fatty acids in the raw materials. [0003] At present, my country's waste edible oils and fats have not been rationally utilized. On the contrary, waste cooking oil has be...
