Problems solved by technology

[0004] In recent years, due to the rapid development of the catering industry, waste oil produced by fast food restaurants and restaurants enters rivers, lakes and seas through sewage channels, causing serious domestic waste pollution to the natural environment; if waste oil flows into fast food restaurants and hotels through illegal channels , will seriously affect people's dietary safety, and has become a prominent problem that endangers society

Embodiment 1

[0019] Embodiment 1. 850 kilograms of waste oils are added into the enamel reactor of 2000L, then 510 kilograms of tetraethylenepentamine and 25 kilograms of 20% (mass percentage concentration) caustic soda aqueous solution are added, and the jacket of the enamel reactor is heated by steam and started Stir. During the heating process, a condensing reflux water separation device is used to separate the moisture generated by the reaction (this part of the moisture does not return to the reactor). When the temperature rises to 180°C, the reaction solution begins to boil, and a large amount of water vapor is generated at this time, and all fractions thereof are recovered (cannot be returned to the reactor) as raw materials for other products. When no water vapor is precipitated after 40 minutes of reaction, the temperature begins to continue to rise; keep the temperature at 230°C, heat the reaction for 30 minutes, then stop heating, and after cooling the jacket to room temperature...

Embodiment 2

[0021] Embodiment 2. 855 kilograms of waste oil are added to the enamel reactor of 2000L, and then 515 kilograms of tetraethylenepentamine and 28 kilograms of 20% (mass percentage concentration) caustic soda aqueous solution are added, and the jacket of the enamel reactor is heated by steam and started Stir. During the heating process, a condensing reflux water separation device is used to separate the moisture generated by the reaction (this part of the moisture does not return to the reactor). When the temperature rises to 180°C, the reaction solution begins to boil, and a large amount of water vapor is generated at this time, and all fractions thereof are recovered (cannot be returned to the reactor) as raw materials for other products. When no water vapor precipitates after 45 minutes of reaction, the temperature begins to continue to rise; keep the temperature at 230°C, heat the reaction for 30 minutes, then stop heating, and after cooling the jacket to room temperature w...

Embodiment 3

[0023] Embodiment 3. 860 kilograms of waste oils are added into the enamel reaction kettle of 2000L, then add 520 kilograms of tetraethylenepentamine and 30 kilograms of 20% (mass percentage concentration) caustic soda aqueous solution, the jacket of the enamel reaction kettle is heated by steam and started Stir. During the temperature rise process, the condensation reflux water separation device is used to recover the moisture generated by the reaction (this part of the moisture does not return to the reactor). When the temperature rises to 180°C, the reaction solution begins to boil, and a large amount of water vapor is generated at this time, and all fractions thereof are recovered (cannot be returned to the reactor) as raw materials for other products.

Abstract

The invention discloses a high temperature resistant oil-in-water emulsifier with high performance. The oil-in-water emulsifier is prepared through the following steps: adding 850-860kg of illegal cooking oil into a 2000L enamel reactor, then adding 510-520kg of tetraethylenepentamine and 25-30kg of 20% sodium hydroxide aqueous solution, introducing steam by a jacket for heating and starting up stirring; in the process of raising the temperature, recovering water generated by reaction by a condensing reflux water division device, and beginning to boil a reaction material when the temperature is raised to 180-190 DEG C, continuously raising the temperature, keeping the temperature at 230-250 DEG C to heat for 40min, then stopping heating, and reducing the temperature by introducing coolingwater through the jacket; and cooling the reaction material to the room temperature, and then discharging and barreling. The reasonable utilization of wastes is realized, the illegal cooking oil harmful to human bodies is prevented from entering fast-food restaurants and wineshops, and an environment-friendly, healthy and safe solution is provided for solving the illegal cooking oil problem.

Description

technical field [0001] The invention relates to the technical field of drilling and oil production, in particular to a preparation method and application method of a high-temperature-resistant high-performance oil-in-water emulsifier. Background technique [0002] The oil-in-water emulsified drilling fluid system is mainly used to solve some drilling reservoir protection problems with low porosity, low permeability, well-developed fractures and cavities, low formation pressure coefficient and technical problems of underbalanced drilling in deep wells. It consists of water phase, oil phase, emulsifier and other treatment agents, in which the water phase is the external phase and the oil phase is the internal phase. Its advantages are as follows: stable system performance, strong temperature resistance, good fluidity, low fluid loss, and strong ability to stabilize the wellbore wall; its density is lower than that of ordinary drilling fluid systems, and the damage to the reser...
