Energy-saving and environment-friendly distillation recovery device

Abstract

The invention provides an energy-saving and environment-friendly distillation recovery device which comprises a distillation tank, a middle tank, a material receiving tank, a recovery tank and a filtering tank, a feeding hopper is arranged on one side of the distillation retort, a distillation outlet is formed in the top end of the distillation tank, and a steam inlet pipe is communicated between the distillation outlet and the material receiving tank; a heating device is arranged at the bottom end of the distillation tank, a material containing cavity is fixed to the upper end of the heating device, the bottom end of the material containing cavity is communicated with the recovery tank through a recycling pipe, and the recovery tank is communicated with the filtering tank through a liquid pumping pipe. According to the invention, the water resource is fully utilized, the water is recycled, the middle tank is used for realizing multiple purposes of the water, the residual liquid after distillation is treated and can be reused, and even if the residual liquid finally needs to be discharged to the outside, the residual liquid is filtered, so that the environmental pollution is avoided. The device is energy-saving, environment-friendly and high in practicability.

Description

technical field [0001] The invention belongs to the field of energy saving and environmental protection, and in particular relates to an energy saving and environmental protection distillation recovery device. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire components. There are two types of evaporation and condensation. A union of unit operations. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not need to use other solvents other than the system components, so as to ensure that no new impurities will be introduced. "Distillation equipment" is a separation technology carried out under high vacuum conditions. It has the characteristics of low distillation temperature, high vacuum deg...

Problems solved by technology

[0003] However, the existing distillation equipment tends to waste water resources to a certain extent, because the collection of distillation condensation requires cooling water to condense, and a large amount of water is also required in the later cleaning process of the distillation tank, which is often not treated after use It will be discharged directly, which will easily pollute the environment and cause waste of water resources.
