At present, common foul waste gas processing method has absorption process, absorption method, bioanalysis, heat accumulating type oxidizing process, plasma cracking method, UV photodestruciton method, chemical oxidization method, plants essential oil encapsulation method etc.Absorption process utilizes stripping liquid process waste gas, with one or more mixtures reclaimed or remove out in waste gas, the material of high concentration can be recycled, but its adsorption effect has selective, and the large usage quantity of adsorbent, floor space is also comparatively large, and absorbent and the insufficient feature of exhaust gas contact, in use applicability is limited.Absorption method utilizes the poisonous and harmful element in solid absorbent absorption waste gas, and minimizing technology is simple, Be very effective, but its adsorbent capacity is limited, is applicable to the process of low-concentration organic exhaust gas, need consider the regeneration issues of adsorbent during use.Bioanalysis adopts specific micropopulation to odorant pollutant of degrading, and energy consumption is low, but the condition of culture of microorganism is more difficult.Heat accumulating type oxidizing process is that foul waste gas is preheating to uniform temperature, then adopts the mode of burning to be decomposed by odorant, non-secondary pollution, but its investment and operating cost relatively high.Plasma cracking method adopts high voltage electric field electric discharge, and clearance is high, but affects by exhaust gas concentration etc., and its danger is high, there is potential safety hazard.UV photodestruciton method adopts high energy UV photon cracking organic molecule, but affects by waste gas humidity etc., and its removal effect is unstable.Chemical oxidization method adopts strong oxidizer oxidation odorant pollutant, easy control of reaction conditions, easy to operate, but there is expensive, selective strong, oxidant the mixes inequality difficult problem with waste gas of oxidant, in the urgent need to reliable treating apparatus conbined usage.Although plants essential oil encapsulation method can cover up stench peculiar smell at short notice, can not malodor molecule be removed, the control overflow of atmosphere pollution can not be met.
Summary of the invention
The purpose of this utility model is to overcome that the removal efficiency that existing feed manufacturing exhaust gas treatment technology exists is low, cost is high, oxidant mixes with waste gas in inequality, waste gas pollution control and treatment and produces the excessive difficult problem of secondary pollution, purifier volume, provide a kind of structure simple, removal efficiency is high, cost is low and the deodorizing purifier of a kind of feed manufacturing waste gas of non-secondary pollution.
Implementation of the present utility model is, a kind of deodorizing purifier of feed manufacturing waste gas, it is characterized in that: comprise cyclone dust collectors, pipeline flow mixing device, gaseous oxidation agent generator, oxidation reaction apparatus, absorption secure device, blower fan, feed manufacturing waste gas input port is provided with bottom described cyclone dust collectors, cyclone dust collectors top is provided with feed manufacturing waste gas delivery outlet, feed manufacturing waste gas delivery outlet is connected to pipeline flow mixing device air inlet, pipeline flow mixing device air outlet is connected to oxidation reaction apparatus air inlet, gaseous oxidizer generator exports is connected to pipeline flow mixing device air inlet, oxidation reaction apparatus air outlet is connected to absorption secure device air inlet, absorption secure device air outlet is connected to blower fan.
Preferably, the described oxidant of gaseous oxidizer generator exports tentatively mixes in pipeline flow mixing device with the foul gas of cyclone entrance;
Preferably, in described oxidation reaction apparatus, be provided with spiral-flow type reactor, feed manufacturing waste gas and oxidant are mixed fully in oxidation reaction apparatus.
Preferably, adsorbent device is provided with in described absorption secure device;
A deodorizing purifier for feed manufacturing waste gas, its implementation comprises the steps:
(1) feed manufacturing waste gas is passed into cyclone dust collectors, remove dust, particle etc. in feed manufacturing waste gas;
(2) oxidant that the waste gas of cyclone entrance and gaseous oxidation agent generator produce tentatively is mixed in pipeline flow mixing device, be then delivered to oxidation reaction apparatus together;
(3) waste gas fully mixes in oxidation reaction apparatus with oxidant, because oxidant has extremely strong oxidability, and can by the most of odorant oxidation in waste gas, degraded;
(4) gas after oxidative degradation is passed into absorption secure device, the regeneration of adsorbent organic substance and adsorbent hockets;
(5) arranged by the clean gas after absorption secure device outward by blower fan.
Preferably, above-mentioned steps (4) be by step (3) be oxidized, degraded after gas be input to absorption secure device in, when in mist, odorant is greater than gaseous oxidizer, unnecessary odorant is fallen by by adsorbent, when in mist, gaseous oxidizer is greater than odorant, gaseous oxidizer is by adsorbent, because gaseous oxidizer has the ability of oxidation odorant, be oxidized the odorant of absorption in early stage by the gaseous oxidizer adsorbed, adsorbent is regenerated, and solves the difficult problem that the adsorbent replacement cycle is frequent, change difficulty.
Principle of the present utility model passes into gaseous oxidizer in oxidation reaction apparatus, and they are the extremely strong active particles of oxidisability, and the malodor molecule that can be oxidized, degrade in feed manufacturing waste gas, reaches the object of odorless non-secondary pollution mass emissions.Not by the foul waste gas molecule of gaseous oxidizer oxidation Decomposition, it can thoroughly remove by the adsorbent in absorption secure device, makes purification feed manufacturing waste gas reach clean emission object.
The beneficial effects of the utility model are: one, have employed spiral-flow type reactor in oxidation reaction apparatus, gaseous oxidizer is fully contacted with feed manufacturing waste gas, substantially reduce the volume of oxidation reaction apparatus, the oxidant solving the existence of existing treating apparatus mixes inequality, causes the difficult problem that oxidant is wasted and toxic emission is not up to standard with waste gas; The design of two, adsorbing secure device solves on the one hand poor selectivity, the halfway difficult problem of process waste gas that gaseous oxidizer process odorant exists, and also solves a difficult problem for short, regeneration difficulty in adsorbent service life on the other hand.
