Description
Technical Field
[0001] The utility model relates to the technical field of humidifying equipment, in particular to a multi-section wet film humidifier. Background Art
[0002] An evaporative wet film humidifier (hereinafter referred to as a wet film humidifier) is a device that humidifies by using the evaporation principle. It evaporates water into water vapor and releases it into the air, thereby increasing the indoor humidity. This humidification method can not only effectively increase the moisture content in the air, but also has the effects of cooling and purifying the air. The evaporative wet film humidifier mainly consists of a wet film component, a housing, a spray pipe, etc. Its core component is the evaporation medium wet film component, which is usually made of plant fiber or glass fiber added with special chemical raw materials and fixed at the front and back and upper and lower ends of the frame. It has good water absorption and evaporation performance. Specifically, when working, water is sprayed from a water distributor (spray pipe) above the wet film component and flows down along the wet film component. On the outer surface of the wet film component, heat and moisture exchange occurs between water and air. After water absorbs heat, it vaporizes and evaporates, thereby achieving the purpose of humidifying and cooling the air. The evaporative wet film humidifier has many advantages. First of all, it is an isenthalpic humidification process, with clean and pollution-free humidification, and has the effects of cooling and purifying the air. Secondly, there are no special requirements for water quality, and general tap water can be used for operation. In addition, it has good hydrophilicity and water distribution performance, high humidification efficiency, energy conservation and environmental protection, a compact structure, and a small floor area, and is suitable for various environmental conditions. Therefore, it has been widely used in production workshops, public places, etc.
[0003] Although the existing evaporative wet film humidifiers meet the usage needs to a certain extent, due to structural limitations, there are still some technical problems to be solved urgently. First: Its wet film component is of an integral structure, with a large outer shape, which will bring certain inconveniences to installation and subsequent maintenance (such as damage or damage to the surface of the wet film cloth that needs to be replaced and maintained. Second: Both the wet film component and the spray pipe component are installed in the housing in a fixed manner. When it is necessary to maintain the wet film component, etc., usually the upper cover of the housing, the spray pipe at the upper end, and the bolts fixing the wet film frame need to be disassembled first before the wet film component can be taken out (the reverse operation is for installing the wet film component). The above operation process is relatively cumbersome, which will bring inconvenience to the staff and is not conducive to improving work efficiency accordingly. Summary of the Utility Model
[0004] In order to overcome the disadvantages of the existing evaporative wet film humidifier due to structural limitations as described in the background art, the utility model provides a multi-section wet film humidifier in which the wet film component is divided into multiple sections and connected by a chute method. When replacing or maintaining the wet film component, only the side cover plate needs to be removed, and then all the wet film components can be pulled out, which brings convenience to the staff and accordingly improves the maintenance and installation work efficiency.
[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows:

The shape of each set of wet film assemblies becomes smaller and the weight becomes lighter. When replacing or maintaining the wet film assemblies, only the side cover plate needs to be removed, and then all the wet film assemblies can be pulled out, which brings convenience to the staff and correspondingly improves the maintenance and installation work efficiency. To sum up, this new type has good application prospects. Description of the Drawings
