Kettle type heat exchange separator

Abstract

The invention discloses a kettle type heat exchange separator which comprises a kettle body (1), wherein a U-shaped shell-and-tube heat exchanger (2) is arranged in the kettle body (1); wherein the top of the kettle body (1) is provided with a feeding hole (3) and a silk screen filtering condenser (4); the feeding pipe (3) is connected with a feeding distributor (6) positioned at the bottom of theU-shaped shell-and-tube heat exchanger (2) through a pipeline (5); an air outlet (7) is formed in the top of the silk screen filtering condenser (4); and a dissolved matter discharge port (8) is formed at the bottom of the kettle body (1). According to the kettle type heat exchange separator, in the separation process, carbon dioxide and methyl alcohol are thoroughly separated, the loss of carbondioxide is reduced, the product quality is improved, and the production cost is reduced.

Description

Technical field[0001]The invention relates to a kettle-type heat exchange separator, which belongs to the technical field of separators.Background technique[0002]In the supercritical carbon dioxide drying device, the complete separation of the dissolved matter and carbon dioxide is particularly important, which is directly related to product quality and raw material costs. The separation method adopted in the prior art is still the isothermal and pressure-reducing separation method. The separation method usually consists of a separation heater, a vertical separation kettle and auxiliary pipeline valves. In the separation method of the prior art, the dissolved matter carried by carbon dioxide does not have enough space for gas-liquid separation, which causes the dissolved matter to circulate into the system along the top carbon dioxide outlet, which affects product quality and a large amount of carbon dioxide escapes with the bottom methanol. This leads to poor product quality stabil...
