Embodiment 1

[0055] Such as figure 1 As shown, a special ventilation equipment for an environment-friendly and corrosion-resistant laboratory includes a kiln body, including a fume hood, an experimental box is set on the top of the fume hood, an experimental cavity is set in the experimental box, and a resistant The corrosion-resistant coating or embedded layer is made of polytetrafluoroethylene.

[0056] Ventilation equipment is arranged on the upper part of the experimental box; the ventilation equipment includes a suction pipe, a self-filtering device and a non-contact wind pressure control device, one end of the suction pipe is connected to the experimental cavity, and the other end of the suction pipe is connected to Self-filtering device and non-contact air pressure control device.

[0057] Such as figure 2 As shown, the self-filtering device can suck the gas in the experimental cavity through the suction pipe; the self-filtering device includes a functional shell, and the air inl...

Embodiment 2

[0072] In this embodiment, the ventilation equipment communicates with the experimental cavity and the storage space of the experimental equipment respectively through the suction pipe, and the first suction valve is set on the suction pipe connected with the experimental cavity, and is connected with the storage space of the experimental equipment. A second suction valve is arranged on the suction pipe connected in space. The upper part of the experimental cavity is hemispherical, which can prevent experimental gas from accumulating at the upper corner of the experimental cavity. Such as Figure 6 As shown, the lower part of the fume hood is provided with an experimental equipment storage space, and several grid bars are respectively arranged on the upper top surface and the lower bottom surface of the experimental equipment storage space, and there is a clamping space between adjacent grid bars. ; A space partition can be inserted into the clamping space.

Abstract

The invention discloses an environment-friendly and corrosion-resistant type ventilating device special for a laboratory and belongs to the field of devices special for laboratories. The device is characterized in that the device comprises a ventilating cabinet; an experiment box is arranged on the upper portion of the ventilating cabinet and internally provided with an experiment cavity; and a corrosion-resistant coating or embedded layer is arranged in the experiment cavity and is of a teflon material. By adoption of the environment-friendly and corrosion-resistant type ventilating device, experiment conditions which are more convenient and faster can be provided; since the corrosion-resistant coating or embedded layer is arranged in the experiment cavity, experimental facilities can be prevented from being corroded or damaged, and the device is more durable; the experiment cavity can be used for further treating smoke more scientifically and more reasonably, harmless treatment is achieved during sucking, the experiment process is safer and more controllable, and the personal safety and health conditions of experimental personnel are practically protected; in addition, since a condensate guiding and colleting device is arranged, condensate can be prevented from flowing back into the experiment cavity; and the device is further provided with an air exhausting and pressure maintaining-regulating device, and pressure in the laboratory can be guaranteed to be precisely adjustable.

Description

technical field [0001] The invention belongs to the field of special laboratory equipment, and in particular relates to an environment-friendly and corrosion-resistant laboratory special ventilation equipment. Background technique [0002] The structure of the traditional laboratory fume hood is relatively simple, simply equipped with experimental space, exhaust fan and related auxiliary equipment for air supply and power supply. However, when the old-style fume hood is actually used, there are often problems such as exhaust gas escaping, pollution or toxic gas collection is not timely and sufficient, causing environmental pollution and even endangering the health and safety of experimenters. Especially the specific experiments that must be carried out in the fume hood often involve the combustion process. While generating a large amount of smoke, the temperature of the smoke is high, and a large amount of condensed water will be generated in the pipeline during the discharg...
