Induction gas feeding and discharging system

Abstract

The invention relates to an induction gas feeding and discharging system and airflow pattern automatic control system in factory using jet fan. The induction gas feeding and discharging system includes: a frame (1) provided on the center walls and two side walls of the factory; at least one placing table (2) provided with extending from the center of the frame to the inner of the factory; a jet fan (3) provided on the top of the placing table (2) for rotating and adjusting up and down angle, guiding and supplying fresh air to the inner of the factory easily, by high speed jet pumping drainage, and guiding the circumjacent polluted air to the main airflow area and inflowing together to realize exhausting. Moreover, the invention also provides an airflow pattern automatic control system including a guiding air feed part (A) and a guiding air renewal part (B). The invention can carry out the airflow pattern control for easily changing the main airflow direction based on outside air wind direction, thereby the air renewal efficiency of the factory reaches maximum.

Description

technical field [0001] The invention relates to a guided air supply and exhaust system in a factory using a jet fan and an automatic airflow pattern control system. Background technique [0002] The present invention configures the jet fan in an optimal state in shipyards where welding fumes, dust, gases, etc. are unavoidable, and in single factories with open entrances and exits in other heavy industry fields and in semi-open conjoined factories. The jet fan simply guides and supplies fresh air, and, through the high-speed ejection and exhaust of the jet fan, guides the surrounding polluted air to the main air flow area and makes them flow together, thereby achieving high exhaust efficiency and at the same time , In the factory, the air flow spectrum control that simply changes the direction of the main air flow according to the direction of the external air flow can be carried out, so that the ventilation of the factory can be optimized. [0003] Generally, shipyards and ...

Problems solved by technology

[0004] In the above-mentioned factories, processing materials have the characteristics of generating a large amount of welding fume, dust, gas, etc., which are not conducive to the working environment and harmful to the health of the workers. Some factories simply rely on rotary electric fans to ventilate the inside of the factory. Therefore, instead of improving the ventilation inside the factory, it is in a state of deterioration. Therefore, it is necessary to propose a fundamental method that can always maintain a comfortable state inside the factory. sexual solution
