[0003] Authorization announcement number CN212731453U discloses a laboratory fresh air circulation dust removal system. This patented technology incorporates a pre-filter, activated carbon filter, medium-efficiency filter, and HEPA filter in the dust removal device. The pre-filter filters large outdoor particles, the activated carbon filter filters toxic gases, the medium-efficiency filter filters airborne dust, and the HEPA filter filters other airborne particles. A groove is provided in the inner cavity of the base, with a baffle and a dust collection box inside. A spring is installed on the upper wall of the baffle and the inner cavity of the base, and the spring is movably connected to the pre-filter. When the pre-filter moves under the influence of wind, large particles on the pre-filter fall into the dust collection box. However, this solution fails to consider the humidity of the outside air when exchanging air between the laboratory and the outside. If the humidity of the outside air is too high, it can easily cause rust and damage to the equipment inside the laboratory. Therefore, a fresh air system for dust removal in large laboratory instrument rooms is needed to address this problem. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example: Please refer to Figures 1-4 The large instrument room dust removal fresh air system shown includes a main body 1, and a ventilation and dust removal component 2 is fixedly connected to the top of the main body 1; In this embodiment, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the ventilation and dust removal assembly 2 includes a first carrier box 201, a second carrier box 202 fixedly connected to the side of the first carrier box 201, a control box 203 fixedly connected inside the first carrier box 201, a suction dust removal box 204 fixedly connected to the side of the control box 203, a connecting hopper 205 fixedly connected to the side of the suction dust removal box 204, a conveying pipe 206 fixedly connected to the side of the connecting hopper 205, a bracket 207 fixedly connected to the top of the second carrier box 202, a drying pipe 208 installed inside the bracket 207, and a [missing information - likely a conduit or component] fixedly connected to the top of the drying pipe 208. Heat exchanger 209 dries the gas transported by PE round pipe 211 using drying pipe 208 and heat exchanger 209. Its drying intensity is high. Due to the high airflow velocity, the particles are well dispersed in the gas phase. The entire surface area of ​​the particles can be used as the effective drying area to dry the fresh air of instrument chamber 101. This means that ventilation and protective equipment can be eliminated during equipment production and maintenance. During production or use, the metal particles generated have less harm to the switch equipment that is insulated by dry air, thereby reducing the damage of humid air to the internal components of instrument chamber 101.

[0019] The conveying pipe 206 extends into the drying pipe 208. Two supports 207 are provided. A fan 210 is installed on the top of the drying pipe 208, and a PE round pipe 211 is fixedly connected to the top of the fan 210. A terminal 212 is fixedly connected to the side of the drying pipe 208. A perforated frame 213 is fixedly connected inside the second carrier box 202, and a fan 214 is fixedly connected inside the perforated frame 213. Several fans 214 are provided. The fans 214 deliver the air inside the instrument chamber 101 to its top. The suction dust removal box 204 delivers the gas inside the instrument chamber 101 to the conveying pipe 206, and then the conveying pipe 206 delivers it to the drying pipe 208. The fan 210 then draws the gas inside the drying pipe 208 through the PE round pipe 211. When exhausting air and introducing fresh air, the fan 210 can be controlled to transport air from the PE round pipe 211 to the drying pipe 208. The air is dehumidified through the drying pipe 208 and the heat exchanger 209, and then transported to the delivery pipe 206. After being filtered and adsorbed by the suction dust removal box 204, the air enters the instrument chamber 101. The fan 214 sends the air inside the instrument chamber 101 to its top. This not only has the advantages of low air loss and fast air exchange, but also the smooth interior of the PE round pipe 211 and the continuous pipe leading to the instrument chamber 101 result in a higher air yield, lower air loss, and faster air exchange. Furthermore, the installation and construction are convenient. Since the top air supply method does not interfere with underfloor heating, etc., and there are fewer connecting parts, the installation and construction method is simple.

[0020] In this embodiment, reference is made to Figure 1 and Figure 2 As shown, the main body 1 includes an instrument compartment 101. The side walls of the instrument compartment 101 are made of PVC panels. A temperature sensor 102, model TMP36, is fixedly connected inside the instrument compartment 101. A humidity sensor 103, model SHT20, is also fixedly connected inside the instrument compartment 101. The PVC panels used in the instrument compartment 101 are an improvement on the second-generation ceiling material PVC, also known as UPVC. It has basically overcome the problems of PVC being easy to age, easy to fade, and not flame retardant. It has made great progress in terms of strength and toughness, and is relatively easy to install and disassemble. It has a high cost performance and is a common material in construction.

[0021] In this solution, the dust removal and fresh air system for the large instrument room in the laboratory uses a fan 214 to send the air inside the instrument chamber 101 to its top. The suction dust removal box 204 then transports the gas inside the instrument chamber 101 to the delivery pipe 206, and then from the delivery pipe 206 to the drying pipe 208. The fan 210 then discharges the gas inside the drying pipe 208 through the PE round pipe 211. When fresh air is introduced, the fan 210 can be controlled to transport the air from the PE round pipe 211 to the drying pipe 208. The air is dehumidified through the drying pipe 208 and the heat exchanger 209, and then transported back to the delivery pipe 206. After being filtered and adsorbed by the suction dust removal box 204, the air enters the instrument chamber 101.
