Ventilation equipment for preparing chlorine gas in chemical laboratory

Abstract

The invention discloses ventilation equipment for preparing chlorine gas in a chemical laboratory. The ventilation equipment comprises an equipment outer frame, a driving motor, a pressurization chamber and an absorption box, wherein the driving motor is arranged inside the equipment outer frame, the driving motor is in wire connection with a power supply and a switch, the absorption box is arranged on the right side of the driving motor, the upper part of the driving motor is rotationally connected with a crankshaft, the upper end of the crankshaft is in bearing rotary connection d with the upper wall of the equipment outer frame, the bending part of the crankshaft is sleeved with the left end of a connecting rod, the pressurization chamber is arranged on the right side of the crankshaft,the pressurization chamber is fixed at the upper end of the adsorption box, moreover, a through groove is formed in the left side wall of the pressurization chamber, the connecting rod penetrates through the through groove and is rotationally connected to the center of the left side surface of a plunger, a suction pipe connecting port is formed in the center of the right side wall of the pressurization chamber, a gas guide pipe is arranged at the bottom of the right side of the pressurization chamber, the gas guide pipe communicates with the lower part of the interior of the absorption box, and one-way valves are arranged at the end parts of the suction pipe connecting port and the gas guide pipe correspondingly.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a ventilation device for preparing chlorine gas in a chemical laboratory. Background technique [0002] Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances ; Drying and selection of grain; Wind tunnel wind source and inflation and propulsion of hovercraft, etc. The working principle of the fan is basically the same as that of the turbo compressor, but because the gas flow rate is low and the pressure changes little, it is generally not necessary to consider the change of the gas specific volume, that is, the gas is treated as an incompressible fluid. [0003] Experiments in the laboratory often involve some toxic gases. The most common is the experiment of preparin...

Problems solved by technology

[0003] Experiments in the laboratory often involve some toxic gases. The most common is the experiment of preparing chlorine gas in the laboratory. High school chemistry often requires experiments, but the existing laboratory ventilation equipment only has the function of ventilation. , does not have the effect of strongly absorbing and absorbing poisonous gas, and there is a risk of poisonous gas leakage causing casualties
