Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, and more specifically, to evaporation equipment for chemical industry. Background Art

[0002] During the concentration process, some chemical solutions require evaporation of a suitable amount of water to obtain a concentrated solution. Traditional reactors often use negative pressure pumping to extract the evaporated water vapor, directly removing the water vapor. However, the temperature at the pipe edge is lower than that inside the reactor, causing water droplets to liquefy there. These droplets, under their own weight, drip back into the solution, affecting evaporation efficiency and resulting in poor overall results. Accordingly, this utility model proposes evaporation equipment for chemical applications. Utility Model Content

[0014] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See also Figure 1 and Figure 2 As shown, the chemical evaporation equipment involved in this embodiment includes a reactor 1, a maintenance port 2 is provided on the top of the reactor 1, a concentrated liquid discharge port 3 is provided on the bottom, a raw liquid inlet 4 near the bottom is provided on the side of the reactor 1, an electric heating component 5 near the bottom and a condensation component 6 near the top are provided in the reactor 1, the condensation component 6 includes a plurality of condensing pipes 61 extending along a straight line, and two adjacent condensing pipes 61 are connected end to end by a series elbow 62, one end of the outermost condensing pipe 61 has a condensate input port 63, and one end of the other condensing pipe 61 has a condensate output port 64, all condensing pipes 61 pass through the reactor 1 laterally, and the condensing pipes 61 are arranged at an angle, and a water collecting tank 7 is provided below the condensation component 6. The water collecting tank 7 is in a closed ring shape, and the outer tank wall of the water collecting tank 7 is provided on the inner wall of the reactor 1, and the side of the reactor 1 is provided with a drain outlet 8 connected to the water collecting tank 7.

[0018] Furthermore, the distances between two adjacent condensation tubes 61 are equal.

[0019] Furthermore, the inclination angle of the condenser tube 61 is 15° with the horizontal plane.

[0020] Furthermore, the condenser tube 61 is a stainless steel tube.

[0021] In this embodiment, the solution to be evaporated and purified is first injected into the reactor 1, and then the electric heating component 5 is powered on to boil it. The water vapor rises and comes into contact with the condensation component 6 into which condensed water is passed. The water vapor is cooled and liquefied, forming a liquid film on the surface of the condenser tube 61. The liquid film gradually grows into droplets and seeps along the inclined wall of the condenser tube 61, and finally seeps from the inner wall of the reactor 1 into the water collecting tank 7 and is discharged from the drain outlet 8.

[0022] Example 2

[0023] See also Figures 1 to 3 As shown, the chemical evaporation equipment involved in this embodiment is further configured on the basis of Example 1, in which a fluoroplastic sleeve 9 is provided on the condenser tube 61 .

[0024] In this embodiment, by providing a fluoroplastic sleeve 9 on the stainless steel condenser 6, not only the good rigidity of the stainless steel condenser 6 is retained, but also the fluoroplastic sleeve 9 prevents the acidic solution formed by the acidic gas in the steam from corroding the condenser 6.

[0025] Example 3

[0026] See also Figures 1 to 3 As shown, the chemical evaporation equipment involved in this embodiment is further configured on the basis of Example 2, in which the cross section of the fluoroplastic sleeve 9 is in the shape of an inverted water droplet.

[0027] In this embodiment, by setting the cross section of the fluoroplastic sleeve 9 to an inverted water drop shape, the rapid discharge of the condensate can be promoted, and the growth of the liquid film on the tube wall can be inhibited, thereby reducing the thermal resistance and improving the heat exchange performance of the condenser.

[0028] The chemical evaporation equipment involved in the utility model heats the solution to evaporate water, and the evaporated water is liquefied into water again on the condenser in the form of water vapor, and finally flows into the water collecting tank along the inclined condenser and the inner wall of the reactor, and is automatically discharged from the drain port without water vapor output, with high concentration efficiency, complete overall functions and strong practicality.
