Cold-air-resistant haze removal door hopper system based on check valve principle

Abstract

The invention discloses a cold-air-resistant haze removal door hopper system based on the check valve principle. The cold-air-resistant haze removal door hopper system comprises a space parameter type selection module, a windproof component type selection module and a video recognition control module. The space parameter type selection module is used for averaging drawing and actually-measured door bucket space parameters in a range of average value +/-standard deviation of respective dimensions, and selecting data serving as a space parameter adjustment step length and a threshold value; performing simulation of a plurality of wind environment working conditions on a gate bucket sample generated by an exhaustion method through CFD simulation software to obtain a preferred database; the windproof component type selection module comprises an air guide plate component and check valve components, the air guide plate component is arranged on the side wall face of the door bucket, the check valve components of multiple stages are fixed to the top of the door bucket through mounting grooves, and openings of the check valve components are arranged in the windward direction; and the video identification control module controls the opening and closing size and the opening and closing speed of the automatic door in real time by exciting a preset program.

Description

technical field [0001] The invention relates to the field of door bucket systems, in particular to a door bucket system for anti-cold air and haze removal based on the principle of a check valve. Background technique [0002] Tall space building is a type of building space with high space height and large single-storey area. For example, due to the high flow of people, the entrances and exits of high-speed railway station buildings are frequently opened during operation, resulting in cold air intrusion and indoor air pollution problems at the entrances in winter, which are more serious than other tall buildings. Existing research shows that the impact of infiltration wind on building load accounts for 66% to 85% of the building load in tall spaces, which is significantly higher than that in ordinary office and residential buildings. [0003] The existing patents and papers closest to the present application are as follows: [0004] 1) A passive solar house with a vertical ...

AI Technical Summary

Problems solved by technology

It effectively solves the problem that the windproof potential of the door bucket cannot be fully tapped at present, and can effectively improve the role of the door bucket as a buffer space to weaken the wind speed and purify the air
