Chemical rectification equipment

Abstract

The invention provides chemical rectification equipment which comprises a reaction kettle and a rectification cavity arranged on the upper side of an outlet of the reaction kettle; the rectification cavity comprises a filler section arranged on the upper side of the outlet of the reaction kettle and a cooling section arranged on the upper side of the filler section, and a first returned material collector is arranged between the cooling section and the filler section; the first returned material collector comprises more than one first collecting tank horizontally and uniformly distributed above a filler pressing plate, a first buffer tank communicated with the first collecting tank, and a first collecting pipe communicated with the first buffer tank; the first collecting pipe is communicated with a discharging port through a discharging pipe, the discharging pipe is provided with a first valve and a sampling port, the first collecting tank is provided with more than one first overflowport. The chemical rectification equipment has the beneficial effects that the reflux ratio can be accurately controlled in real time, then the product quality can be stabilized, and production energyconsumption is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a chemical distillation equipment. Background technique [0002] Rectification is an important step in chemical production. Controlling the reflux ratio in the rectification process is an important factor that determines product quality. In the prior art, the condenser and the rectification column are separately installed. The reflux ratio controller is used to realize the shunt flow and control the reflux ratio. It uses the chip to control the opening and closing time of the solenoid valve to control the amount of reflux. However, the reflux ratio controller can only realize the reflux flow control, but cannot realize the reflux distribution of the reflux liquid. It needs to add an additional distributor, the structure is complicated, and the original reflux ratio controller can only control the reflux liquid after passing through the condenser. The reflux of the pro...

[0002] Rectification is an important step in chemical production. Controlling the reflux ratio in the rectification process is an important factor that determines product quality. In the prior art, the condenser and the rectification column are separately installed. The reflux ratio controller is used to realize the shunt flow and control the reflux ratio. It uses the chip to control the opening and closing time of the solenoid valve to control the amount of reflux. However, the reflux ratio controller can only realize the reflux flow control, but cannot realize the reflux distribution of the reflux liquid. It needs to add an additional distributor, the structure is complicated, and the original reflux ratio controller can only control the reflux liquid after passing through the condenser. The reflux of the product is controlled. On the one hand, it is impossible to realize reflux control or recycling processing of high-boiling point materials, which virtually increases the production cost and installation cost. On the other hand, the original reflux ratio controller cannot realize real-time reflux, resulting in the hidden danger of unstable production quality

[0003] The rear section of the condenser of the original distillation equipment is connected to a reflux ratio controller to control the return and discharge of the material. It is necessary to vacuum the collection tank to discharge the material smoothly, which increases the energy consumption of the equipment and the production cost.
