[0002] In modern industrial production, especially in the electronics, pharmaceutical, food and other industries with high precision requirements, the environmental quality of the cleanroom is directly related to product quality and production efficiency. A cleanroom refers to a working environment that meets specific standards for indoor environmental parameters such as dust concentration, temperature, humidity and pressure through specific design and control. In order to maintain a high cleanliness environment in a cleanroom, an efficient air purification and circulation system is required.

[0003] Traditional air purification systems usually use centralized air treatment devices, such as the air handling unit (AHU) in the central air-conditioning system. Although these systems can purify the air and adjust the temperature and humidity to a certain extent, they have the following problems: centralized air treatment systems often occupy a large area and have complex pipeline layouts, which increases investment costs and difficulty in operation and maintenance; the air circulation speed is limited by the system design, which may lead to untimely air renewal in some areas of the dust-free workshop, affecting the cleanliness; large-scale centralized systems are difficult to achieve rapid purification and temperature and humidity control of local spaces, and cannot provide customized services for areas with special requirements; the noise generated by the system operation may interfere with the working environment in the dust-free workshop; the energy consumption is high, which is not conducive to energy conservation, emission reduction and sustainable development.

[0004] In view of the above problems, the industry is in urgent need of a new type of internal circulation dust removal device, which should have the ability to quickly and efficiently replace the air in the dust-free workshop, while taking into account the convenience of installation, stability of operation and simplicity of maintenance to meet the needs of different areas and different cleanliness levels.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0032] See also Figure 1-7 As shown, the utility model is an internal circulation dust removal device, including an air filter 1, a return air guide box 2, an outlet air guide box 3, an air guide main pipe 4 and an air guide assembly 5. The air filter 1 includes an air guide box body, an axial flow fan and a high-efficiency filter installed in the air guide box body. The return air guide box 2 is installed on one side wall in the dust-free workshop, the air filter 1 is installed on the same side wall outside the dust-free workshop, and the return air guide box 2 is connected to the air filter 1. Several outlet air guide boxes 3 are installed on the other side wall opposite to the dust-free workshop, and several outlet air guide boxes 3 are connected to the air guide main pipe 4.
