Description
Technical field
The utility model relates to a kind of emission-control equipment, relates in particular to waste scavenging device in starch production process.
Background technology
Starch Production adopts sulfurous acid to soak corn, by the effect of sulfurous acid and lactic acid, softening corn particle, destroy the somatic protein net of embryo, dissolve the part solable matter in corn particle, improve fragmentation and the effect separating, but also produce gas with foreign flavor simultaneously, mainly sulfur dioxide, methyl mercaptans etc. have the gas of penetrating odor, environmental pollution is larger, the solution adopting in currently available technology is in scrubbing tower, to neutralize to reach the object of removing sulfur dioxide etc. and have the sour gas of penetrating odor with alkali lye, but, because alkali lye produces heat in course of reaction, easily volatilization, removal effect is not thorough, in addition, the methyl mercaptan that alkali lye absorbs is not effectively processed, easily produce secondary pollution.
Utility model content
In view of the above, be necessary to provide one can fully remove waste scavenging device in starch production process.
Waste scavenging device in a kind of starch production process, comprise waste gas collection device, absorption tower, Jia Jian mechanism, add dithionate mechanism, circulating pump and heat exchanger, described waste gas collection device is arranged on absorption tower one side, by pipeline and absorption tower internal communication, described Jia Jian mechanism, add dithionate mechanism and be arranged on absorption tower opposite side, all be communicated with absorption tower, described circulating pump is arranged on absorption tower on one side, at the bottom of going deep into absorbing tower by pipeline one end, the other end gos deep into tower top inside, absorption tower, and described heat exchanger is arranged on circulating pump pipeline.
Further, this device arranges device for discharging, and this device for discharging is arranged on bottom, absorption tower, is communicated with absorption tower by pipeline.
Further, one end that the connecting pipe on described circulating pump and absorption tower is goed deep into tower top inside is provided with shower nozzle.
Further, described shower nozzle is multiple.
Further, described shower nozzle is six.
Further, described waste gas collection device is induced-draught fan.
Compared to prior art, in starch production process of the present utility model, waste scavenging device adds dithionate mechanism and heat exchanger by setting, effectively remove the waste gas such as sulfur dioxide and methyl mercaptan, remove effect better, effectively prevent from removing the secondary exhaust gas thoroughly not causing and pollute.
Brief description of the drawings
Fig. 1 is the structural representation of waste scavenging device in the utility model starch production process.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, waste scavenging device in the utility model starch production process, it comprises waste gas collection device 10, absorption tower 20, Jia Jian mechanism 30, adds dithionate mechanism 40, circulating pump 50 and heat exchanger 60.Described waste gas collection device 10 is arranged on absorption tower 20 1 sides, by pipeline and absorption tower 20 internal communication, for waste gas being sent into absorption tower 20.Described Jia Jian mechanism 30, add dithionate mechanism 40 and be arranged on absorption tower 20 opposite sides, be respectively used to add to absorption tower 20 alkali lye and dithionate solution.Described circulating pump 50 is arranged on absorption tower 20 on one side, and at the bottom of going deep into absorption tower 20 towers by pipeline one end, the other end gos deep into 20 tower top inside, absorption tower, for the liquid of circulating absorption tower 20 inside, gas is carried out to washing absorption.Described heat exchanger 60 is arranged on circulating pump 50 pipelines, for reducing the temperature of circulation fluid, greatly strengthens the effect of liquid absorption gas.
Further, in order to make this device can continuous operations, increase by a device for discharging 70, this device for discharging 70 is arranged on 20 bottoms, absorption tower, passes through pipeline communication.Process after a period of time when absorbing, can introduce a casing by absorbing treatment fluid, the alkali lye more renewing and dithionate solution, ensure better scavenging.
Further, one end that the pipeline that connects described circulating pump 50 and absorption tower 20 gos deep into tower top inside is provided with shower nozzle 22.Described shower nozzle 22 can be multiple multilayer settings.In the present embodiment, shower nozzle 22 is two-layer setting, and every one deck is six.
Further, described waste gas collection device 10 is induced-draught fan, is communicated with in 20 bottoms, absorption tower by pipeline, and the effect of collecting waste gas in order to increase can arrange multiple.
While using in starch production process of the present utility model waste scavenging device, induced-draught fan sucks the waste gas producing in starch production process in 20 bottoms, absorption tower, described Jia Jian mechanism 30, add dithionate mechanism 40 interior alkali lye and the dithionate solution of adding respectively to absorption tower 20 simultaneously, circulate alkali lye and dithionate solution to fall from tower top spray by circulating pump 50, make it to carry out reactive absorption with waste gas, when alkali lye absorbs sour gas, dithionate is oxidized methyl mercaptan.
To sum up, in starch production process of the present utility model, waste scavenging device adds dithionate mechanism 40 and heat exchanger 60 by setting, effectively remove the waste gas such as sulfur dioxide and methyl mercaptan, remove effect better, effectively prevent from removing the secondary exhaust gas thoroughly not causing and pollute.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
