Description

Technical Field

[0001] The utility model relates to the field of high-efficiency formaldehyde evaporators, and particularly to a high-efficiency formaldehyde evaporator. Background Technique

[0002] Industrial formaldehyde evaporators are key equipment used in industrial production to convert formaldehyde liquid into formaldehyde gas. Utilizing the heat provided by the heating system, the formaldehyde liquid rapidly heats up and evaporates into gas in the evaporation chamber. During the evaporation process, appropriate working conditions are maintained through the temperature and pressure control systems, and the formaldehyde gas generated by evaporation is transported to subsequent production links after passing through the gas-liquid separation device.

[0003] Existing evaporators use stirring of formaldehyde liquid to increase the evaporation effect, but this method is relatively single, and it is difficult for heat to enter the interior of the formaldehyde liquid, which may cause the heat not to be transferred to the formaldehyde liquid quickly and evenly, thus prolonging the evaporation time and reducing production efficiency; the existing evaporators have poor heat insulation effect, so a large amount of heat will be dissipated to the surrounding environment through the surface of the evaporator during use, resulting in the need to consume more energy to maintain the temperature required for evaporation and increasing the energy cost.

[0004] Therefore, those skilled in the art have provided a high-efficiency formaldehyde evaporator to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a high-efficiency formaldehyde evaporator is proposed. The air pump drives the rubber plug to move downward, so that it extracts the formaldehyde liquid through the first delivery pipe. When the rubber plug moves upward, part of the extracted formaldehyde liquid is discharged through the slots opened on the outer side of the second delivery pipe to play a stirring role, and the other part is sprayed in the form of atomization through the atomizing nozzle, thereby accelerating heat transfer and enabling the formaldehyde liquid to be converted into gas faster, significantly shortening the evaporation time and thus improving production efficiency; the fixedly arranged rock wool layer has a low thermal conductivity and can effectively prevent heat transfer. The fiber structure of the glass wool layer gives it excellent heat insulation effect and can effectively block heat transfer, thereby effectively preventing the heat inside the evaporator from diffusing to the external environment and significantly reducing energy consumption and saving production costs.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high-efficiency formaldehyde evaporator, including a main body, a stirring mechanism is fixedly arranged at the lower end of the main body, a heating mechanism is fixedly arranged below the inner surface of the main body, a heat exchanger is fixedly arranged above the inner surface of the main body, and a demister is fixedly arranged above the heat exchanger on the upper inner surface of the main body;

The rock wool layer has a low thermal conductivity and can effectively prevent the transfer of heat.

[0013] Further, hinge blocks are fixedly arranged on the inner surfaces above the two first delivery pipes. A first fixing block is fixedly arranged on one side of the inner surfaces above the two first delivery pipes and located at the hinge block. A second fixing block is fixedly arranged on the other side of the inner surfaces above the two first delivery pipes and located at the hinge block;

[0014] Through the above technical solution, the hinge block facilitates sealing and opening the first delivery pipe by rotating. The first fixing block holds the hinge block in place, so that when the rubber plug moves upward, the formaldehyde liquid can quickly push the hinge block to one end. The second fixing block facilitates limiting the hinge block, and they cooperate to play a sealing role.

[0015] Further, second delivery pipes are fixedly arranged on the inner sides of both sides in the middle of the second outer shell. A plurality of slots are formed on both sides of the two second delivery pipes, and two adjacent slots among the plurality of slots are arranged at equal intervals;

[0016] Through the above technical solution, the second delivery pipes facilitate the delivery of the formaldehyde liquid. The formaldehyde liquid is discharged through the plurality of formed slots to play a stirring role, and the evaporation effect is enhanced through stirring.

[0017] Further, a first outer shell is fixedly arranged outside the air pump, and the output end of the air pump is fixedly arranged with the lower side of the rubber plug;

[0018] Through the above technical solution, the first outer shell facilitates the installation and protection of the air pump. The air pump is fixedly arranged with the lower side of the rubber plug through the output end, so that it can drive the rubber plug to move.

[0019] Further, an air inlet pipe is fixedly arranged on one side of the main body, a pipeline is fixedly arranged on the other side of the main body, and an air outlet pipe is fixedly arranged on the upper side of the main body;

[0031] Refer to Figures 1-4 , an embodiment provided by the present invention: A high-efficiency formaldehyde evaporator, including a main body 3, a stirring mechanism 4 is fixedly arranged at the lower end of the main body 3, a heating mechanism 7 is fixedly arranged below the inner surface of the main body 3, a heat exchanger 6 is fixedly arranged above the inner surface of the main body 3, a demister 5 is fixedly arranged above the heat exchanger 6 on the upper side of the inner surface of the main body 3, a glass wool layer 9 is fixedly arranged on one side of the inner side of the main body 3, a rock wool layer 8 is fixedly arranged on the other side of the inner side of the main body 3, an inlet pipe 2 is fixedly arranged on one side of the main body 3, a pipe 10 is fixedly arranged on the other side of the main body 3, and an outlet pipe 1 is fixedly arranged on the upper side of the main body 3.

[0032] The main body 3 facilitates the installation of more mechanisms of the device and at the same time plays a sealing role. The stirring mechanism 4 stirs and sprays formaldehyde liquid, thereby enhancing the evaporation effect, significantly shortening the evaporation time, and thus improving the production efficiency. The heat exchanger 6 facilitates heating the vaporized formaldehyde. The demister 5 removes the liquid droplets or mist entrained in the gas. The fiber structure of the glass wool layer 9 gives it excellent heat insulation effect, which can effectively block the transfer of heat and reduce energy consumption.

The inlet pipe 2 facilitates the delivery of air into the mechanism, the pipe 10 facilitates the delivery of formaldehyde liquid, and the outlet pipe 1 discharges the formaldehyde gas for subsequent use.

[0033] Refer to Figures 1-4, the stirring mechanism 4 includes a second outer shell 404. Above both sides of the second outer shell 404, a first delivery pipe 408 is fixedly arranged. Above the upper side of the second outer shell 404, an atomizing nozzle 403 is fixedly arranged. On the inner surface of the second outer shell 404, a rubber plug 411 is slidably arranged. At the lower end of the rubber plug 411, an air pump 401 is fixedly arranged. On the inner surface above the two first delivery pipes 408, a hinge block 405 is fixedly arranged. On one side of the hinge block 405 on the inner surface above the two first delivery pipes 408, a first fixing block 406 is fixedly arranged. On the other side of the hinge block 405 on the inner surface above the two first delivery pipes 408, a second fixing block 407 is fixedly arranged.

The air pump 401 drives the rubber plug 411 to move upward, so that the hinge block 405 abuts against the second fixing block 407 for sealing. The extracted formaldehyde liquid is discharged through the plurality of slots 410 opened in the second delivery pipe 409 to stir the formaldehyde liquid placed in the main body 3. The remaining extracted formaldehyde liquid is sprayed through the atomizing nozzle 403, thereby improving the evaporation effect of the formaldehyde liquid. The evaporated formaldehyde gas is heated through the heat exchanger 6, and then the liquid droplets or mist entrained in the gas is removed through the demister 5, and finally discharged through the air outlet pipe 1.
