Description
Technical field
Patent of the present invention relates to a kind of environmental protecting device and method, is specifically related to a kind of device and method for the foul gas Photolytic deodorization.
Background technology
Along with making constant progress of society, manufacture the industries such as industry, diet service trade day by day flourish, but the toxic harmful rotten gas that each enterprise gives off every day has greatly polluted the airspace that we depend on for existence.Different production facilities and process can produce various foul gas.Can produce the foul smell such as ammonia, amine, sulfide, fatty acid, aromatic series and dimethyl disulfide in the garbage compost process.Good oxidation and sludge air drying process can produce mercaptan, dimethyl disulfide and a small amount of hydrogen sulfide.At present, commercial production, municipal wastewater, Treatment of Sludge and refuse disposal facility etc. are the main sources of these foul gass.
Foul gas is of a great variety, and wide material sources all can cause in various degree murder by poisoning to human body respiration, digestion, cardiovascular, endocrine and nervous system, and wherein aromatic compound such as benzene, toluene, styrene etc. can also make human body produce distortion, canceration.Foul gas generally acknowledged by countries in the world as a kind of typical environmental hazard, and many developed countries are studied it as a kind of single-row public hazards, and control is implemented in special legislation.China is for controlling odorant pollutant to the pollution of atmosphere; protect and improve environment and also put into effect the GB14554-93 standard; stipulated the once maximum emission limit of eight kinds of odorant pollutants, factory's circle concentration limit in the odor concentration limit value of compound odorant and uncontrollable discharge source.
At present, the technical method of international and domestic improvement foul gas has: firing method, catalytic oxidation, ozone removal method, active carbon adsorption, medicinal liquid spray process and biological odor removal method.Although these methods have obtained certain achievement on foul gas is processed, exist in varying degrees equipment investment large, the operational management cost is high; Treating capacity is little, takes up room large; Process not thoroughly, cause secondary pollution; Job insecurity, the shortcoming such as energy consumption is large, and deodorising effect is undesirable.
Summary of the invention
The present invention is directed to the problems such as traditional odor removal operational management cost is high, deodorising effect is undesirable, the device and method that a kind of operating cost is low, deodorization efficiency is high is provided.
Photolytic deodorization device involved in the present invention mainly is comprised of air inlet (1), housing (2), baffle plate (3), quartz burner (4), gas outlet (5) etc.Wherein air inlet (1) is positioned at the lower left of housing, and foul gas enters from air inlet; Housing (2) is the main body of whole device, and other parts are played the support assosting effect; Baffle plate (3) be shaped as 5 square and 5 semicircles, wherein leave the circular hole that can pass quartz burner on Semicircular baffle, its installation site as shown in Figure 1, the installation of baffle plate can allow gas along the housing rising of spiraling, gas is played guide functions, extended the time of staying of foul gas in device; Quartz burner (4) evenly is arranged on device inside, is formed by the processes according to fluorescent tube such as filament, quartz glass, ballast, can send the ultraviolet light that main wave band is 253.7nm and 184.9nm; Gas outlet (5) is positioned at the upper right side of housing, discharges from the gas outlet through the gas that ultraviolet light decomposes.In addition, baffle plate and inner walls all scribble the layer of titanium dioxide catalysis material.
The equal paste-making method that the present invention relates to house refuse is mainly realized by following steps:
At first device case is fixing in place, coat the layer of titanium dioxide catalysis material on inner walls and baffle plate, and baffle plate is arranged on as shown in Figure 1 position, the quartz burner that can produce simultaneously 253.7nm and 184.9nm evenly is arranged on device inside.Device switches on power after installing, and until equipment after unloaded 5 minutes, makes the foul gas collected inner through the air inlet access to plant, and under the baffle plate guide functions, foul gas is discharged from the gas outlet at last along the rising of advancing, spiral of baffle plate baffling.The time of staying of foul gas in odor removal is controlled to be 5-10 second.The gas of gas outlet is carried out the field test, detect process the odorants such as hydrogen sulfide, ammonia in foul gas through this device deodorization efficiency higher than 99%, and Staphylococcus albus, colibacillary killing rate are higher than 99.5%.
Photolytic deodorization device provided by the invention and method have following obvious superiority:
(1) apparatus of the present invention Burdick lamp pipe shell used is quartz glass, processes according to fluorescent tube forms, can produce main wave band is the ultraviolet light of 253.7nm and 184.9nm, and the mean transmissivity of ultraviolet light wave is high, and in device, ozone concentration can reach 50-70ppm.
(1) all scribble the layer of titanium dioxide catalysis material on the inwall of device of the present invention and baffle plate, the coordinated ultraviolet can accelerate the photodissociation of foul gas.
(2) flow apron is equipped with in the inside of apparatus of the present invention, can allow foul gas along the housing rising of spiraling, and extends the time of staying of gas in device, makes deodorize more thorough.
(3) device and method provided by the invention need not to add any material, only need to open Burdick lamp, allow foul gas along the device rising of spiraling, the time of staying can reach more than 5 seconds, can make the thorough decomposing, purifying of foul gas, need not to add any material and participate in chemical reaction.
(4) device and method operating cost provided by the invention is low, and there are not mechanical vibration in this equipment running process, and noiselessness need not personal management and regular maintenance, only need do and make regular check on, and the equipment windage is low, can save the air draft power consumption.Pending foul gas need not pass through special pretreatment, and the operating temperature of equipment is that normal room temperature gets final product.
(5) device and method provided by the invention is high to the foul gas odor removal efficient, can efficiently remove the major pollutants such as volatile organic matter, inorganic matter, hydrogen sulfide, ammonia, mercaptan, deodorization efficiency is up to more than 99%, and deodorising effect surpasses the primary standard (GB14554-93) of the odorant pollutant discharging of country's promulgation in 1993.After the treated decomposing, purifying of foul gas, gas reaches the harmless discharge standard fully, can not produce secondary pollution.
