The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
Fig. 1 is the structural representation of first kind of embodiment of the utility model.According to the industrial waste gas flow direction, pass through wet method spray column 1, dehydration tube 8 and dry method adsorption tower 10 successively.
Wherein, wet method spray column 1 comprises liquid storage tank 6, circulating pump 4, shower 3 and is positioned at 2 to 4 layers of inner filter course 2 of tower body.The tower body lower end of wet method spray column 1 is communicated with liquid storage tank 6; The bottom of its sidewall is provided with exhaust gas entrance 5; This exhaust gas entrance 5 is positioned at the below of orlop filter course 2, is provided with the absorption liquid that is used for the absorbing waste gas inorganic constituents in the liquid storage tank 6, and circulating pump 4 connects liquid storage tank 6 and shower 3; The front end of shower 3 is positioned at the top of tower body, filter course 2, and its front end is provided with nozzle.Under the effect of circulating pump 4; It is inner that absorption liquid gets into tower body along shower 3; From the ejection of the nozzle of front end, meanwhile industrial waste gas gets into and moves upward from exhaust gas entrance 5, and promptly the direction of motion with absorption liquid is opposite; 2 places are fully mixed at filter course, the inorganic constituents in the waste gas or be dissolved in absorption liquid or with absorption liquid in active ingredient generation chemical reaction and obtain removing.Dissolved that the absorption liquid of inorganic constituents flows in the liquid storage tank 6 again in the waste gas downwards, be recycled pump 4 once more and send in the shower 3, so moved in circles.
The inorganic constituents that receives in the waste gas after the spray Cleaning for High Capacity is eliminated, and remaining organic principle is mixing steam upwards discharges from the outlet of wet method spray column 1 and get into dehydration tube 8, passes through each eddy flow plate 9 downwards.The number of eddy flow plate 9 is 3 to 5, sets gradually along the axis of dehydration tube 8.This moment, each eddy flow plate 9 played the exsiccation that dewaters step by step.Moist waste gas organic principle becomes dry in this link dehydration, from the outlet entering dry method adsorption tower 10 of below.In order can the liquid that produce in the dehydration tube 8 in time to be discharged, be provided with dewatering outlet 7 in the bottom of cylindrical shell.
Waste gas organic principle after the dehydration gets in the dry method adsorption tower 10.Dry method adsorption tower 10 vertically is provided with, and inlet is positioned at the bottom of its sidewall, and outlet is positioned at its top.Waste gas gets into from the inlet of bottom, moves upward through 2 to 4 layers of adsorption layer 11, is added with the organic gas adsorbent in this adsorption layer 11.Owing to removed the moisture in the waste gas, adsorbent can be brought into play suction-operated efficiently.In this link, the organic principle in the waste gas is fully absorbed, and remaining minor constituent is discharged from the outlet of dry method adsorption tower 10.
Also being provided with discharge duct 13 in the present embodiment is used for final remaining little of gas is expelled to atmosphere.The outlet of dry method adsorption tower 10 is connected to the inlet of this discharge duct 13, for increasing flowability, on the pipeline between the inlet of the outlet of dry method adsorption tower 10 and discharge duct 13, also is provided with air-introduced machine 12.
Fig. 2 is the structural representation of second kind of embodiment of the utility model.Among this embodiment, change dry method adsorption tower 10 into horizontally set by vertical setting, inlet is positioned at the bottom of the distolateral wall of one of which, and outlet is positioned at the top of its other end sidewall, and the remainder of equipment and first embodiment are consistent.The user can select different set-up modes like the size of factory building, the difficult complexity of management according to the concrete condition of enterprise.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
