Description
Technical field
The utility model belongs to environmentally friendly deodorization field, and in particular to a kind of foul waste gas removing system rotation filler dress
It sets.
Background technology
Odor pollution is one of feature pollution of petroleum refining industry, has been recognized by the world today as environmental hazard.
It causes the unhappiness of people by the smell of people first, then by stimulating Sensory nerve's system of people, destroys human body new old generation
It thanks, to cause nerve and menticide.People are lived in for a long time in stench environment, will cause giddy, insomnia, apocleisis, note
Recall the various functions diseases such as power decline and mood agitation, and then influences health.
External advanced country starts to walk early to the Study on treatment technology of odor pollution, and malodorous discharge standard is more demanding.With
The raising of domestic residents living standards and the enhancing of environmental consciousness, the ratio that odor pollution is complained have significant rising.It dislikes in China
In smelly discharge standard, the most important pollutant hydrogen sulfide of petroleum gas chemical industry, methyl mercaptan, methyl sulfide, methyl disulfide etc.
It is listed.
The odor polluting source of petrochemical plant point overhead pollution sources and uncontrollable discharge pollution sources.Overhead pollution sources are mainly
Necessary process gas discharge in process of production, such gas is often through large-scale purifier, such as hydramine method, ammonia process or
Gypsum focused on after by the chimney of certain altitude, the row up to standard under the premise of meeting state environmental emissioning standard
It puts.
In addition it is the main source for refining oil plant area's odor pollution to account for nearly three one-tenth of the uncontrollable discharge source of malodor source sum, these
Malodor source is distributed in most of process units based on sewage farm, product purification retracting device and storage tank zone.With containing
In sulphur crude oil processing, the increase of various medium sulfur content, the type and concentration of the malodorant of these stench source emissions also increase
Add, the run, drip, leak storage tank breathing loss that can't be mainly fully solved on equipment management and manufacturing technology, open-top receptacle
Volatilization.Such gas has overall narrow-minded, stench point dispersion, odour concentration height, contains combustible gas component simultaneously, exists easily
The features such as firing explosive risk.
For this kind of sulphur-containing exhaust gas, currently used Deodor method has combustion method, solution absorption method, solid absorption
Method, biological deodorization method etc., these methods have some limitations and different specific aims.Solid absorption method is in sulphur-containing exhaust gas
Using more in deodorization technique, but that there are adsorbents is hardened, and utilization rate is not high, replaces that risk is high, and local temperature increases after mixing oxygen,
The deficiencies of being easy to happen safety accident；Although sulphur-containing exhaust gas burning can be the sulfur dioxide of free from extraneous odour by combustion method, due to
Waste gas component is complicated, or even contains the hydrocarbonaceous flashed vapour in part, therefore exists and dodge quick-fried equivalent risk；Biological deodorization method mainly utilizes alkali
Property solution or microorganism alkalescence Environmental Chemistry absorb, but there are plant area is larger, biological inoculum stability is poor, mating work
The deficiencies of journey is more.
The mechanism of solvent absorption is related to mass transfer between multiphase flow, heat transfer and reacts, be chemical industry, the energy, environmental protection,
Most basic one of production process in the fields such as material, biochemical industry largely uses packed tower, plate column etc. during these
Mass transfer apparatus, and the liquid phase flowing in equipment often relies on gravity to realize.Since liquid flowing is slow under gravitational field, body
Product mass tranfer coefficient is small, and the production intensity of space availability ratio and equipment is relatively low.Therefore, this kind of equipment is bulky, the throwing of equipment
Money, maintenance cost and energy consumption are higher, are relatively more suitable for large-scale gas purifying technique.
