Vacuum tail gas safe combustion device for biodiesel raw material vacuum distillation

Abstract

The invention discloses a vacuum tail gas safe combustion device for biodiesel raw material vacuum distillation. The vacuum tail gas safe combustion device comprises a coal ball furnace with a tail gas combustion chamber, an explosion-proof temperature detection sensor PT100 thermal resistor, a flame arrester, a pipeline and a valve. A vacuum tail gas access pipe is divided into three paths after being connected with a ball valve, one path is connected with a condensate discharge ball valve and a discharged liquid collecting pipe, the other path is connected with a left ball valve, an anti-detonation pipeline flame arrester and a right ball valve, and the third path is connected with a bypass ball valve and then combined with the second path; after the explosion-proof temperature detection sensor PT100 thermal resistor is mounted, a large pipe branch and a small pipe branch are divided, the large pipe branch consists of a large pipe branch anti-deflagration pipeline flame arrester and a large pipe branch ball valve, the small pipe branch consists of a small pipe branch anti-deflagration pipeline flame arrester and a small pipe branch ball valve, and the two branches are combined and then connected with a combustion chamber tail gas input pipe led into a tail gas combustion chamber; and a steam conveying pipeline is connected with an outlet pipeline of a tail gas access ball valve after being connected with a stop valve. The vacuum tail gas safe combustion device for biodiesel raw material vacuum distillation is convenient and efficient to operate, safe, stable and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of biodiesel raw material processing devices, in particular to a vacuum tail gas safe combustion device for vacuum distillation of biodiesel raw materials. Background technique [0002] At present, the main raw material for biodiesel production is waste animal and vegetable oils. There are many complex low-carbon alcohols, aldehydes, ketones, esters and other substances in waste animal and vegetable oils. These substances have a specific taste and form a vacuum under vacuum distillation conditions. Tail gas, direct exhaust will affect the surrounding atmospheric environment, therefore, it must be disposed of harmlessly, and alkali washing is generally used at present, but this treatment method can only reduce emissions, but cannot fundamentally eliminate exhaust emissions. Contents of the invention [0003] The purpose of the present invention is to provide a convenient, efficient, safe, stable and environ...

[0002] At present, the main raw material for biodiesel production is waste animal and vegetable oils. There are many complex low-carbon alcohols, aldehydes, ketones, esters and other substances in waste animal and vegetable oils. These substances have a specific taste and form a vacuum under vacuum distillation conditions. Tail gas, direct discharge will affect the surrounding atmospheric environment, therefore, it must be disposed of innocuously, and alkali washing is generally used at present, but this treatment method can only reduce emissions, but cannot fundamentally eliminate exhaust emissions
