A plurality of evaporation plates are designed inside the evaporation chamber, and a plurality of evaporation holes are evenly distributed on these evaporation plates to ensure uniform evaporation of formaldehyde. The heating device is cleverly placed on the inner wall of the evaporation chamber to provide the required heat. The condensing device is located above the evaporation chamber and is used to condense the evaporated formaldehyde gas into liquid. The control system is the core of the entire evaporator. It includes a temperature sensor, a controller and an actuator, which can accurately control the heating temperature of the heating device and the condensing temperature of the condensing device to ensure the safety and efficiency of the entire production process.
[0006] Specifically, the evaporation plate is designed in a disc shape with multiple evaporation holes evenly arranged on it to ensure that the formaldehyde can be evenly distributed and evaporated during the evaporation process. This design helps to improve the efficiency and uniformity of formaldehyde evaporation, thereby improving production efficiency.
[0007] The heating device uses electric heating tubes as the main heating element. These electric heating tubes are arranged around the inner wall of the evaporation chamber. This design not only provides uniform heat, but also ensures the stability and controllability of the heating process, thereby ensuring the safety of the formaldehyde evaporation process.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] See also Figure 1The utility model provides a technical solution: a formaldehyde evaporator for the safe production of formaldehyde, which is mainly composed of an evaporation chamber 1, a heating device 2, a condensing device 3 and a control system. A plurality of evaporation trays 5 are designed inside the evaporation chamber 1, and a plurality of evaporation holes 6 are evenly distributed on these evaporation trays 5 to ensure uniform evaporation of formaldehyde. The heating device 2 is cleverly placed on the inner wall of the evaporation chamber 1 to provide the required heat. The condensing device 3 is located above the evaporation chamber 1 and is used to condense the evaporated formaldehyde gas into liquid. The control system is the core of the entire evaporator. It includes a temperature sensor 4, a controller 7 and an actuator, which can accurately control the heating temperature of the heating device 2 and the condensing temperature of the condensing device 3 to ensure the safety and efficiency of the entire production process.
[0017] Specifically, the evaporation plate 5 is designed in a disc shape with multiple evaporation holes 6 evenly arranged on it to ensure that the formaldehyde can be evenly distributed and evaporated during the evaporation process. This design helps to improve the efficiency and uniformity of formaldehyde evaporation, thereby improving production efficiency.
[0018] The heating device 2 uses electric heating tubes as the main heating element, which are arranged around the inner wall of the evaporation chamber 1. This design not only provides uniform heat, but also ensures the stability and controllability of the heating process, thereby ensuring the safety of the formaldehyde evaporation process.
[0019] The condensing device 3 consists of a condensation pan 3-1 and a condensation tube 3-2. The condensation pan 3-1 is located above the evaporation chamber 1, while the condensation tube 3-2 is located above the condensation pan 3-1. This design makes the condensation process more efficient, quickly condensing the evaporated formaldehyde gas into liquid, thereby improving the efficiency and safety of the entire production process.
[0020] Controller 7 in the control system controls the operation of the actuators based on the detection results of temperature sensor 44. The actuators are responsible for adjusting the heating temperature of heating device 2 and the condensing temperature of condensing device 3, ensuring that the entire formaldehyde evaporation process proceeds under optimal conditions, thereby improving production efficiency and safety. This precise control effectively avoids safety accidents caused by temperature runaway and ensures smooth formaldehyde production.
[0021] Working principle: Formaldehyde solution is introduced into the evaporation plate 5 in the evaporation chamber 1. There are multiple evaporation holes 6 distributed on the evaporation plate 5. These holes allow the formaldehyde solution to pass through and form a thin layer to increase the surface area in contact with the heat source, thereby promoting evaporation.
[0022] The heating device 2, specifically an electric heating tube, is arranged around the inner wall of the evaporation chamber 1 to provide uniform heat to the evaporation chamber. The heat of the heating device 2 is transferred to the formaldehyde solution in the evaporation plate 5 and the evaporation holes 6, causing it to evaporate.
[0023] Temperature sensor 4 in the control system monitors the temperature within evaporation chamber 1. Controller 7 controls the actuator based on feedback from temperature sensor 4. The actuator adjusts the heating temperature of heating device 2 to ensure that the formaldehyde solution evaporates at an appropriate temperature, avoiding decomposition or other side reactions caused by overheating.
[0024] The formaldehyde vapor generated by evaporation rises above the evaporation chamber 1 and is condensed by the condensation pan 3-1 and condensation tube 3-2 in the condensation device 3. The condensation device 3 condenses the formaldehyde vapor into liquid formaldehyde through the condensation pan 3-1 and condensation tube 3-2 and collects it in a container below the condensation device.
[0025] The control system also controls the condensation temperature of the condensing device 3 to ensure effective condensation of formaldehyde vapor while avoiding energy waste caused by too low a condensation temperature or formaldehyde loss caused by too high a condensation temperature.
[0026] The entire formaldehyde evaporator ensures efficient and safe production of formaldehyde by precisely controlling the temperature during evaporation and condensation.
