The blowing device provided by the invention can overcome the defect of the blowing device, the overflow loss of sulfide in a blowing process is reduced, the recovery ratio and monitoring quality in the sulfide are improved, the original blowing device is subjected to technological reformation and innovation, and the blowing device is succeeded in the application of monitoring analysis of water quality sulfide.
Description
Technical field
The invention provides the industry sulfides from wastewater such as a kind of iron and steel, chemical industry, petroleum refining and analyze pretreated blowning installation, be used for the pre-service of sulfides from wastewater sample, belong to the environmental monitoring facility.
Background technology
Sulfide is that the waste water of national regulation must be surveyed project.Because of the waste water complicated, the Analysis interference many factors before waste water sulfide sample analysis, must carry out pre-service to sample for this reason.The main method of sample pretreatment at present has zinc acetate precipitation-filtration method, acidifying-air blast, filtration-acidifying-air blowing partition method, and acidifying-air blowing disposal route is used more, and the method need to be used blowing device.The shortcoming such as that existing blowning installation exists is simple and crude, coarse, poor air-tightness, complex structure, air blowing speed are inhomogeneous, make sulfide overflow loss seriously in preprocessing process, measurement result is on the low side, affected the accuracy of data, cover efflux wastewater water quality truth, misled the direction of leader's decision-making and environmental management.The effusion loss of therefore adopting an effective measure and reducing sulfide improves the sulfide recovery and monitoring quality.
Summary of the invention
In order to overcome the defective of original blowning installation, reduce the effusion loss of air blowing process medium sulphide content, improve the sulfide recovery and monitoring quality, the present invention has carried out technological improvement and innovation to former blowning installation, uses and obtained success in the monitoring analysis of water quality sulfide.
the technical solution adopted for the present invention to solve the technical problems is: a kind of sulfides from wastewater is analyzed pretreated blowning installation, comprise source nitrogen, reaction bulb, absorption bottle, glass stopper, silicone tube, glass tube and control folder, the nitrogen tube of source nitrogen is connected with the total glass pipe by silicone tube, install on silicone tube and control folder, draw side by side some glass tubes on the total glass pipe, propping up glass tube is connected in reaction bulb after pressing from both sides with silicone tube and control, glass stopper is set on reaction bulb, vial is provided with small-sized controlled funnel beyond the Great Wall, air intake opening, the gas outlet, the reaction bulb gas outlet causes below absorption liquid in absorption bottle by generating tube, reaction bulb and absorption bottle are put into and are fixed this.
Describedly fix this for double-deck diplopore lazy board.
Use ground glass stopper in described reaction bulb and absorption bottle.
Described absorption bottle is 100 milliliters of color comparison tubes.
The invention has the beneficial effects as follows: because blowning installation of the present invention changes into all-glass, vial is provided with small-sized controlled funnel, air inlet glass tube, the glass tube of giving vent to anger beyond the Great Wall, connect snorkel and change silicone tube into by emulsion tube, and the double-layer porous lazy board of design increase, thereby determined the originally following characteristics of novel blowning installation:
(1) blowning installation is full glass and silicone tube material, makes air blowing process more airtight, has reduced the absorption loss of using rubber plug.
(2) phosphoric acid is added by controlled funnel on bottle stopper, need not uncap, and ground glass stopper is tight, can not cause analysis ingredient H2S to overflow because fall acid in bottle, can reduce the H2S loss of overflowing, and improves the recovery.
(3) connecting pipe changes silicone tube into by emulsion tube, but has reduced the absorption loss of sulfide the serviceable life of extension tube, has improved the accuracy of Monitoring Data.
(4) the wooden fixed support of design, fix reaction bulb and absorption bottle, and is larger because managing interior overbottom pressure when having avoided closing gas cylinder, and the absorption bottle overturning, solution spatters outward and the problem of sulfide loss, makes measurement result more accurate.
(5) this device impermeability is good, has reduced air loss, has improved quality measurement.
The present invention has improved the accuracy of water quality sulfide analysis, has improved the degree of detecting of sample, has realized the accurate monitoring of sulfide, has satisfied the needs of environmental management and scientific research, has filled up the blank of Monitoring Data.
Description of drawings
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is layout.
In figure: 1 reaction bulb, 2 absorption bottles, 3 silicone tubes, 4 glass tubes, 5 control folder, 6 controlled funnels, 7 generating tubes.
Embodiment
As shown in Figure 1 and Figure 2,
a kind of sulfides from wastewater is analyzed pretreated blowning installation, comprise source nitrogen, reaction bulb 1, absorption bottle 2, glass stopper, silicone tube 3, glass tube 4 and control folder 5, the nitrogen tube of source nitrogen is connected with the total glass pipe by silicone tube, install on silicone tube and control folder, draw side by side some glass tubes on the total glass pipe, propping up glass tube is connected in reaction bulb 1 after pressing from both sides with silicone tube and control, on reaction bulb 1, glass stopper is set, vial is provided with small-sized controlled funnel 6 beyond the Great Wall, air intake opening, the gas outlet, reaction bulb 1 gas outlet causes below absorption liquid in absorption bottle by generating tube 7, adjustment fixes the glass stopper frosted mouth of reaction bulb and the glass stopper frosted mouth of absorption bottle.
Totally four groups of above-mentioned reaction bulb and absorption bottles, on two outer three group reaction bottles, the gas outlet connection procedure is same as described above, during use, but another 1 sample of pre-service, and process so continuously a plurality of samples, reaction bulb and absorption bottle are put into and are fixed this.
This sulfides from wastewater is analyzed pretreated blowning installation use procedure: first lead to nitrogen, whether have gas leakage, and adjust and control folder if checking, the pore of each generating tube is given vent to anger unanimously, then closes source of the gas.Add the sulfide sample in small-sized controlled funnel on the reaction bulb, open piston, sample is put into reaction bulb, fasten piston, funnel on reaction bulb adds acid, then opens piston, and reaction bulb is put in acid, fasten again piston, and then connect nitrogen, carry out Pre-treatment of aeration.After pre-service finishes, absorption bottle is covered ground glass stopper, then carry out sample analysis and get final product.
