AI Technical Summary

⚠Technical Problem

Existing high-purity titanium production workshops suffer from problems such as low air exchange efficiency, difficulty in ensuring cleanliness, and high energy consumption. Traditional air conditioning systems are costly and have limited cooling effects, making it difficult to achieve green and low-carbon production.

⚗Method used

The system combines a fresh air filtration device and a rooftop ventilation fan with an electrical control device. A PLC controller enables the fan unit to start and stop in stages and adjust the zones, creating a bottom-up hot air exhaust path. Multiple layers of filter cotton ensure air cleanliness.

🎯Benefits of technology

Significantly improves ventilation efficiency, ensures air cleanliness, reduces energy consumption, improves the working environment, increases production efficiency and worker comfort, and enables intelligent control.

Abstract

This utility model discloses a cooling and ventilation structure for a high-purity titanium production workshop, aiming to solve the technical problems of high ambient temperature, low ventilation efficiency, and high energy consumption in high-purity titanium workshops. The structure includes a fresh air filtration device installed on the exterior windows of the first floor of the workshop to filter incoming fresh air; multiple ventilation fans evenly distributed along the length of the roof on both sides of the roof sunshade to accelerate the exhaust of hot air; and an electrical control device for controlling the operation of the fans. The electrical control device includes a PLC controller and a terminal box. The PLC controller controls the power supply circuit of each fan group through the terminal box, realizing graded start-stop control of the fan groups. This structure achieves efficient ventilation and cooling with large air volume and low energy consumption, while ensuring the cleanliness of the incoming air, effectively improving the thermal environment and working conditions in the high-purity titanium production workshop. It has the advantages of reasonable structure, flexible control, and high energy efficiency.
