Abstract

The invention discloses a method for enhancing urea synthesis, wherein the method comprises a base, wherein the left side of the top part of the base is provided with a stripping tower main body; the bottom parts of both sides of the stripping tower main body are fixedly connected with first brackets, and outsides of the bottom parts of the first brackets are fixedly connected with second brackets; the bottom parts of the second brackets are fixedly connected with the base; the top part of the stripping tower main body is interconnected with an outlet, and the bottom part of the stripping tower main body is interconnected with a fluid flow opening; the right side of the top part of the base is fixedly connected with a heating box, and the inner part of the heating box is crossly and fixedly connected with a baffle; the bottom part of the inner wall of the heating box is fixedly connected with two first heating substrates. When the existed stripping tower is compounded, the temperature rise is slow, thus the synthetic efficiency is low; the method for enhancing urea synthesis speeds up the temperature rise, the synthetic efficiency is high, the user's working efficiency is increased; the method can facilitate use, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of urea synthesis, in particular to an enhanced method for urea synthesis. Background technique [0002] Urea, also known as carbonamide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen, also known as urea, and is a white crystal. One of the simplest organic compounds. Diamide of carbonic acid, molecular weight 60. The main nitrogen-containing end product of protein metabolism and decomposition in mammals and some fishes is also the nitrogen fertilizer with the highest nitrogen content. As a neutral fertilizer, urea is suitable for a variety of soils and plants. It is easy to store, easy to use, and has little damage to the soil. It is a chemical nitrogen fertilizer that is currently used in large quantities. In industry, ammonia and carbon dioxide are used to synthesize urea under certain conditions. [0003] In the production process of urea, it is necessary to use a strippin...
