Embodiment Construction

[0017] Such as figure 1 as shown, figure 1 The control schematic diagram of the fume hood with temperature-proof, smoke-proof and fire-extinguishing function proposed by CIT for the invention.

[0018] refer to figure 1 , a kind of CIT fume hood with anti-temperature, anti-smoke and fire extinguishing function proposed by the present invention, comprising a cabinet body, an air inlet and an air outlet are arranged on the cabinet body, a fan is arranged at the air outlet, and external air can enter through the air inlet Inside the cabinet, the air in the cabinet can be discharged out of the cabinet through the air outlet; specifically, the air inlet is set on the side of the cabinet, and the air outlet is set on the top of the cabinet, which can strengthen the overall air flow inside the cabinet and effectively reduce the The ambient temperature inside the body further enhances the control of smoke emissions.

[0019] There are temperature sensor, smoke sensor, flame detecto...

Abstract

The invention discloses a CIT ventilation cabinet with temperature-proof smoke-proof and fire-extinguishing functions. A temperature sensor and a smoke sensor are arranged at an air outlet part, are respectively used for detecting the real-time temperature value and the real-time smoke quantity inside a cabinet body and are respectively connected to a controller, the controller is used for controlling the rotating speed of a fan according to detection signals of the temperature sensor and the smoke sensor, a flame detector is arranged inside the cabinet body, is used for detecting flame light signals inside the cabinet body and is connected to the controller, a fire extinguishing device is arranged at the side part of the cabinet body and comprises a plurality of spraying mechanisms and a water supply mechanism, the spraying mechanisms are connected with the water supply mechanism through a pipeline, in addition, a control valve is arranged on the pipeline, and the controller is connected with the control valve and is used for controlling the work state of a warning device and the fire extinguishing device according to the detection results of the flame detector. According to the CIT ventilation cabinet, the temperature and the smoke in the ventilation cabinet can be precisely monitored and effectively controlled.

Description

technical field [0001] The invention relates to the technical field of fume hoods, in particular to a CIT fume hood with the functions of preventing temperature, preventing smoke and extinguishing fire. Background technique [0002] At present, the fume hood is a kind of equipment widely used in laboratories, and the use industry is mainly concentrated in scientific research institutions, testing institutions and schools. In order to prevent laboratory workers from inhaling or ingesting some toxic, pathogenic or unknown toxic chemicals and organisms, a good ventilation environment should be maintained in the laboratory. In order to prevent some vapors, gases and particles (including smoke, dust and cyclones) from being absorbed by the human body, the pollutants must be removed by means of fume hoods, fume hoods or local ventilation. And sometimes when the laboratory heats substances in the fume hood or conducts some organic chemical reaction experiments, it is easy to gener...
