Abstract
The invention discloses a device for adsorbing noxious gas. The device mainly comprises an absorbing pool, a tee joint and a rotating valve plug. The absorbing pool is cylindrical, and the upper end of the absorbing pool is open; two sides of the head of the tee joint are provided with a spigotjoint respectively, and the tail end of the tee joint is sealed and matched with the upper end of the absorbing pool; an inner cavity of the tee joint is provided with a built-in pipe; the lower end of the built-in pipe is provided with a bubbler which extends into the absorbing pool; the rotating valve plug is matched with a transverse through hole of the tee joint through a conical surface ground; the valve plug is provided with a corresponding through hole, and a cavity between the built-in pipe and an outer pipe is communicated with one of the spigotjoints. The device is used for chemical experiments and is connected with a reaction tank and a gas pump; when the reaction is complete and signals need not to be acquired, the reacted noxious ga enters absorbing solution from the built-in pipe, is repeatedly circularly until the noxious gas is completely absorbed and is treated intensively so as to avoid polluting the environment. The device has simple structure, convenient operation, reliable seal and good using effect.
Description
Technical field
The present invention relates to a kind of be used for the chemical experiment chemical reaction complete after, utilize micro air pump and absorbent solution, the device that toxic gas is absorbed.
Background technology
In our daily many chemical experiments of carrying out, can produce many poisonous and hazardous materials, for example, mercury (Hg) and compound thereof belong to extremely toxic substance, can accumulate in human body.Many people are being subjected to the harm of mercury unconsciously, and the destruction result of generation is extremely serious, sometimes even the life security that is threatening people.The inorganic mercury ion that enters water body can change the bigger organic mercury of toxicity into, enters human body by food chain, can cause the whole body poisoning.
How these toxic gases that produce in the experimentation are effectively absorbed with focusing on and just become problem of being concerned about very much of people.Now, although ventilation negative pressure cabinet has all been installed in the laboratory,, the result who does so directly is discharged into a large amount of undressed toxic gases in the outdoor environment to go, environment has been caused very big injury, in the long term, the healthy of people remained extremely harmful.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provides a kind of simple in structure, easy to operate, and result of use is good, is applicable to the noxious gas absorbing apparatus of pollution abatement in the chemical experiment.
Technical scheme of the present invention is: noxious gas absorbing apparatus is mainly by absorption cell, three-way connection, rotational valve core constitutes, described absorption cell is the tubular glass container, upper end open, described three-way connection is the tubular glass member that has many passages, the both sides that its head is relative respectively have one to connect mouth, the afterbody mouth of pipe becomes gap-free sealed cooperation with the upper end of above-mentioned absorption cell, inner chamber is provided with built-in pipe, this built-in pipe upper end links to each other with the head of three-way connection, the lower end extend in the absorption cell, the lower end is provided with bubbler, this built-in pipe connects mouth and all is connected with the cross through hole of three-way connection head with above-mentioned two, described rotational valve core is located in the above-mentioned cross through hole, become no gap to be rotatably assorted, the respective through hole that constitutes triple valve is arranged on the rotational valve core, the cavity between the built-in pipe of described three-way connection and the outer tube with above-mentioned one of them connect mouth and be connected.
The upper end of described absorption cell becomes conical surface ground to cooperate with the three-way connection afterbody mouth of pipe; Described rotational valve core becomes conical surface ground to cooperate with the cross through hole of three-way connection, O type rubber ring is housed in the groove of the cone small end of rotational valve core; The bubbler flare of described built-in pipe lower end has the through hole of a plurality of φ 1～1.5mm on the horn mouth end face; The described three-way connection outside is provided with paired upper and lower claw with the absorption cell outside, adorns rubber band on the upper and lower claw; On the described absorption cell graduation mark is arranged.
When this device uses, the mouth that connects of three-way connection both sides is connected with annular seal space, the micro air pump of chemical reaction pond respectively, when chemical experiment is in the demarcation or the state of measurement, regulate rotational valve core, two passages that connect mouth are directly communicated, measured matter is without absorbent solution, and by the signal detection system acquisition testing, experiment is normally carried out; After chemical reaction is complete, when need not to gather signal, regulate rotational valve core, the mouth that connects that connects chemical reaction pond is communicated with the built-in pipe of three-way connection, reacted toxic gas enters absorbent solution through built-in pipe, toxic component is absorbed, and the bubbler of built-in pipe lower end can strengthen assimilation effect, and absorbent solution is prepared according to different toxic gases.The gas that overflows from absorbent solution connects mouth through another and is carried by air pump, constantly circulation absorbs fully until toxic component in airtight pipeline, absorbent solution is focused on again, purified gas can enter atmosphere, thereby effectively avoids the pollution of toxic gas to environment.This apparatus structure is simple, and is easy to operate, and each connecting portion sealing is reliable, and result of use is good.

Fig. 3 is an outline drawing of the present invention.
The specific embodiment
Referring to accompanying drawing, the afterbody mouth of pipe (lower port) of three-way connection 2 becomes no gap to cooperate with the upper port of absorption cell 4, for conical surface ground cooperates, the head both sides of three-way connection are provided with and connect mouth 3 and 8, the inner chamber of three-way connection is provided with built-in pipe 6, built-in pipe extend into the bottom of absorbent solution 7, the built-in pipe lower end is provided with bubbler 5, the horn mouth end face of bubbler 5 has the through hole of 5 φ 1.2mm, rotational valve core 1 is located in the cross through hole of three-way connection head, both become conical surface ground to cooperate, O type rubber ring 9 is housed in the groove of the cone small end of spool, the respective through hole that constitutes triple valve is arranged on the cone of spool, the built-in pipe of three-way connection and the cavity between the outer tube, promptly the cavity on the liquid level top of absorbent solution 7 with connect mouth 3 and be connected.Above-mentioned absorption cell, three-way connection and rotational valve core are all glass workpiece, and the absorption cell and the three-way connection outside are provided with three pairs of corresponding claws 10, adorn rubber band on the claw 10, and there is graduation mark 11 in the absorption cell outside.
When the present invention uses, connect mouth 3 and link to each other, connect mouth 8 and link to each other, gather signal (sample) the input signal detection C of system from chemical reaction pond B with chemical reaction pond B with micro air pump A.After chemical reaction was complete, rotational valve core made to connect mouth 8 and built-in pipe 6 connections, and as shown in Figure 1, reacted toxic gas enters absorbent solution 7, extracts through air pump, gets back to chemical reaction pond by connecing mouth 3 again, and so circulation absorbs fully until toxic component.Demarcate or during the state of measurement when chemical experiment is in, rotational valve core makes to connect mouth 3 and 8 and directly communicate, and as shown in Figure 2, measured matter is without absorbent solution, circulation in pipeline, gathers signal and detects.
