Embodiment Construction

[0034] Attached below Figure 1~3 A preferred embodiment of the multi-stage evaporation and gas-vapor mixing system of the present invention will be described in detail.

[0035] see figure 1 , A multi-stage evaporation and gas-vapor mixing system of the present invention consists of a multi-stage evaporation tower 30, a cascade adjustment system 36 for feeding liquid raw materials, a heater 34 and three nozzles 31, 32, 33.

[0036] see figure 2 , The multi-stage evaporation tower 30 is composed of a tower base 1 and a tower body 10 . The tower body 10 is a tower body 10 divided into three sections by two broken tower plates 6, 9, and the downcomers 3, 22 connecting the upper and lower two sections of the tower body are arranged on the broken tower plates 6, 9. The tower base 1 and the tower body 10 are connected by welding, and all liquid evaporation and gas-liquid mixing steps are performed in the tower body 10 .

[0037] Inside the tower body, the broken tower plates 6...

Abstract

The invention relates to a multi-stage evaporation and air-vapour hybrid system and method thereof, comprising a multi-stage evaporation tower, a cascade control system for feeding a liquid charging stock, a heater and three nozzles. The multi-stage evaporation tower comprises a tower body and a tower base divided into three segments with two dividing tower plates. The tower body is provided with an air-vapour outlet, a feeding inlet, an air-vapour inlet, a liquid outlet and a leakage fluid drain. The method provided by the invention comprises the following steps: the liquid charging stock is shunted and regulated through the cascade control system, and then fed into an upper tower body of the multi-stage evaporation tower and the heater, and a liquid mixture is heated in the heater. The air is loaded into the nozzle, the liquid mixture is mixed and evaporated in the heater, then air-vapour mixture is fed into the multi-stage evaporation tower. The air-vapour mixture product is discharged from the top and a residual liquid is further discharged. The invention realizes multi-stage evaporation and condensation of the mixture liquid through a plurality of nozzles and multi-stage evaporation tower system, and control is simple.

Description

technical field [0001] The invention belongs to the field of liquid evaporation and gas-liquid mixing, in particular to a liquid evaporation and gas-vapor mixing system and method composed of multiple nozzles and multi-section evaporation towers. Background technique [0002] Liquid evaporation and gas-liquid mixing are widely used in petroleum, chemical, metallurgy, pharmaceutical and other industries. For the evaporation of the liquid mixture and its mixing with the gas, most of the equipment in the prior art uses multiple evaporations in different evaporators, and then introduces the gas to mix with the steam. The disadvantage of adopting this method is that the number of required equipment is large, the floor area is large, and its control is complicated. [0003] The method of the prior art is: the liquid is evaporated first, and then the gas is introduced. There are two disadvantages in this way. One is that the liquid must be heated above its boiling point temperatu...
