Description
Technical field
The utility model relates to a kind of laboratory instrument, especially a kind of laboratory chlorine dioxide generator.
Background technology
Because in the tradition sterilization, the organism reaction in chlorine and the water generates disinfection byproduct (DBP) (as haloform, halogen acetic acid etc.), the health of human body is worked the mischief, people are seeking a kind of alternative sterilizing agent always in recent years, with the assurance safety of drinking water.Dioxide peroxide is the A that The World Health Organization (WHO) and the World Food Programme (FAO) are recommended to the whole world
1Level wide spectrum, efficient and safe sterilizing agent; Be considered to best one of the sterilizing agent that substitutes.But the dioxide peroxide purifying drinking water also has its limitation, at first is that cost is higher, and its cost is 2～4 times of chlorine disinfectant cost; Next is perfect not enough to the detection means of lower concentration dioxide peroxide and relevant composition thereof; Also produce some by products in the dioxide peroxide scavenging process besides, the toxicity of its main by product chlorite and oxymuriate is also required further study.Therefore, be necessary that Depth Study is carried out in the sterilization to dioxide peroxide in the laboratory.Generally there is the working cost height in the chlorine dioxide generator of experiment usefulness, the not enough problem of perhaps made dioxide peroxide system purity now.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, result of use good, easy to operate easy laboratory chlorine dioxide generator.This device has simple and feasible, and working cost is low, and the characteristics of high safety can prepare highly purified dioxide peroxide.
The utility model is achieved through the following technical solutions:
A kind of laboratory chlorine dioxide generator, this producer mainly is made of reactor, feed system, buffering system, gathering system, and said system connects by pipeline.
And, described reactor is a four-hole boiling flask, feed system is two ground constant voltage cylindrical separatory funnels, buffering system is made up of a buffering wide-necked bottle and a buffering Erlenmeyer flask, gathering system is made up of placed in-line three receiving flasks and an absorption bottle, its order of connection is to be connected with buffering wide-necked bottle, two ground constant voltage cylindrical separatory funnels on the four-hole boiling flask respectively, and connects buffering Erlenmeyer flask and placed in-line three receiving flasks by triplate line, and receiving flask connects absorption bottle.
And the opening part of described buffering wide-necked bottle, four-hole boiling flask, receiving flask is embedded with the stopper of punching, and pipeline is tightly connected by stopper and above-mentioned instrument.
And, two valves are housed on the described triplate line.
Advantage of the present utility model and positively effect are:
The utility model is reasonable in design, easy for installation, have simple structure, economical and practical, safe and reliable, advantage that efficient is high, the purity of chlorine dioxide that generates with this producer can reach more than 95%, so the utility model can be applicable to the prepared in laboratory high-pure chlorinedioxide, experimental study carries out disinfection.
Description of drawings
Fig. 1 is a setting drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but is not limited to the concrete structure that present embodiment is narrated.
A kind of laboratory chlorine dioxide generator, as shown in Figure 1, this producer mainly is made of reactor, feed system, buffering system, gathering system, and said system connects by pipeline.
Above-mentioned reactor is a four-hole boiling flask 11, feed system is two ground constant voltage cylindrical separatory funnels 4 and 6, buffering system is made up of a buffering wide-necked bottle 3 and a buffering Erlenmeyer flask 14, gathering system is made up of placed in-line three receiving flasks 16 and 17 and 18 and absorption bottles 20, its order of connection is that 8 mouthfuls of four-hole boiling flask are connected with the buffering wide-necked bottle, 7 mouthfuls of four-hole boiling flask connect ground constant voltage cylindrical separatory funnel 4,9 mouthfuls of four-hole boiling flask connect ground constant voltage cylindrical separatory funnel 6,10 mouthfuls of four-hole boiling flask connect buffering Erlenmeyer flask and placed in-line three receiving flasks by triplate line, and receiving flask connects absorption bottle.Two valves 13 and 15 are housed on the above-mentioned triplate line.
The opening part of above-mentioned buffering wide-necked bottle, four-hole boiling flask, receiving flask is embedded with the stopper of punching, and pipeline is tightly connected by stopper and above-mentioned instrument.
This device is provided with nitrogengas cylinder 1 before reactor, guarantee that complete assembly is in slight positive pressure state, helps the absorption of chlorine dioxide and the security of assurance device.Be provided with buffering wide-necked bottle and spinner-type flowmeter 2 before the four-hole boiling flask, for the adjustments of gas flow to guarantee a whole set of reaction unit air pressure balance.Adopt ground constant voltage cylindrical separatory funnel as feeder, can regulate controls reaction speed, strengthened the security of device.Admission passage partly extends drag in the reactor, and is designed to the microbend shape in the bottom, can play stirring action, and reaction solution is mixed.The air outlet is divided into two-way by Y-tube, and one the tunnel feeds in the open buffering Erlenmeyer flask, and one the tunnel feeds in the receiving flask.
Using method of the present utility model:
The utility model when operation, open thermostat water bath 12 earlier, regulate water temperature to 70 ℃, connect device by above-mentioned mode of connection, simultaneously placed in-line three receiving flasks are put into ice-water bath 19.A thermostat water bath is established in reactor four-hole boiling flask bottom, and four-hole boiling flask is fixing by iron clamp platform 5, and its bottom is immersed in the thermostat water bath fully.
Put into certain density sodium chlorate solution in the four-hole boiling flask, put into the vitriol oil of certain volume in the ground constant voltage cylindrical separatory funnel 4, put into certain volume and certain density hydrogen peroxide in the ground constant voltage cylindrical separatory funnel 6, add certain amount of urea (urea is as the stablizer of hydrogen peroxide) in the hydrogen peroxide.After the reaction solution preheated one-section time, feed nitrogen, drip the vitriol oil earlier, drip hydrogen peroxide again, drip the hydrogen peroxide afterreaction and pick up counting.During the reaction beginning, the purity of chlorine dioxide of generation is not enough, opens valve 13 valve-offs 15, and the gas of generation feeds buffering Erlenmeyer flask 14; Reaction beginning back 5-10min, stable reaction is opened valve 15 valve-offs 13, collects chlorine dioxide, with the purity of chlorine dioxide that guarantees to absorb.About reaction 1h, after the interior gas color of four-hole boiling flask is thin out, take out three air collectors immediately, put into refrigerator and keep in Dark Place.Open valve 13 valve-offs 15, allow reaction solution continue reaction, after reacting completely, turn off nitrogen, termination reaction.
