Description
Technical field
The utility model relates to exhaust-gas treatment, especially relates to a kind of exhaust treatment system of energy-conserving and environment-protective.
Background technology
China has become the second largest in the world plastics consumption big country after the U.S., and only use amount in 2013 is more than 6,000 ten thousand tons.
Used heat thermoplastic plastic is easy to regeneration, has abundant raw material sources, has again wide market, is easy to processing, small investment, instant effect.
Existing plastic reclaimed industry, is mostly family workshop type, small scale, eager for instant success and quick profits, often causes serious pollution transportation and secondary pollution.
Mainly waste water and exhaust emission in the pollution of current plastic reclaimed industry.Because the plastic component reclaimed is complicated, the refuse ratio be mingled with is high, complicated, and because the plastics of complexity mix, fusing point differs, enough plasticizings are devoted exclusive attention to output and ensured in producer, blindly improve melt temperature, such as, LDPE fusing point in waste plastics is about 100 DEG C, HDPE also just about 130 DEG C, existing granulation barrel zone temperature is often heightened to 450 DEG C, even more than 500 DEG C, considerably beyond the decomposition temperature about 310 DEG C of PE, polyethylene is caused to degrade in a large number, produce a large amount of alkanes waste gas and foreign material anoxic in machine barrel " is smouldered ", produce a large amount of toxic gas, contaminated environment and infringement workers ' health.
Because waste plastics processing must through cleaning, though through drying process, its moisture content is still between 25% ~ 35%, thus the steam containing a large amount of high temperature in waste gas is produced, owing to being in semi-closed state in machine barrel, thus produce heat steam, infrared observation directly perceived is at 120 ~ 140 DEG C, have a strong impact on workshop temperature, workman is difficult to stand.
Summary of the invention
The purpose of this utility model is for Problems existing in current plastic granulating industry, provides and utilizes waste gas residual heat, focuses on waste gas to reach the exhaust treatment system of a kind of energy-conserving and environment-protective of national waste gas emission standard.
The utility model is provided with jatharapanvartanasana hot channel, sprayed tank, dry adsorption tanks;
The external waste gas of import of described jatharapanvartanasana hot channel is bled fan outlet, and sprayed tank is provided with spray tank body, waste gas inlet pipe, air chamber, the 1st baton round packing layer, the 2nd baton round packing layer, the 3rd baton round packing layer, circulation alkali flow container, pump and sprayed tank gas outlet; The outlet of the external jatharapanvartanasana hot channel of air inlet of waste gas inlet pipe, the gas outlet of waste gas inlet pipe is located at above air chamber, air chamber, the 1st baton round packing layer, the 2nd baton round packing layer, the 3rd baton round packing layer are by being horizontally set in spray tank body from bottom to up successively, circulation alkali flow container is located at spray tank base, circulation alkali flow container is connected with the spray wands be located at above the 1st baton round packing layer, the 2nd baton round packing layer, the 3rd baton round packing layer with pipeline respectively through pump, and the refluxing opening of air chamber is connected with circulation alkali flow container by pipeline;
Sprayed tank gas outlet is connected with the air inlet being located at dry adsorption tanks bottom by pipeline, in dry adsorption tanks tank body, level is provided with the 1st grade of packed quick lime packing layer, the 2nd grade of packed quick lime packing layer, 3rd level packed quick lime packing layer, packed active carbon filler layer, bulk active carbon filling material layer successively from bottom to up, is located at the exhaust outlet externally connected exhaust pipe at dry adsorption tanks tank body top.
Described sprayed tank tank base and dry adsorption tanks tank base can establish pedestal, and described sprayed tank tank body and dry adsorption tanks tank body can establish observation inspection opening.
Usually; at plastic granulator, each produces the origination point of waste gas; fan housing and supporting high pressure positive blower is all adopted to collect waste gas; and at storing mesa base, hot channel is installed; its waste heat is utilized to be dried as far as possible by the material moisture content in storing platform; utilize the waste gas of waste heat on the other hand, sent into the utility model through air exhauster, process to qualified discharge.
Spray-adsorbent equipment of the present utility model is made up of two tank bodies.Because waste gas has certain corrosivity, useable glass steel construction, there are enough capacity, such as the large-scale board of daily output (24 hours continuously) more than 10 tons, its sprayed tank tank diameter > 2.5m, height > 4m, dry adsorption tanks can be more smaller, and process can be abundant.
Four layers are divided in sprayed tank, every layer separates (as done grid plate with perspex steel) with grid plate and guarantees to breathe freely, ground floor is air chamber, built-in venting chambers 1/2 height 5% NaOH solution, gas inlet mouth down, press close to alkali lye liquid level (can not insert in alkali lye, otherwise load is too large) more than three layers every layer dress this layer 1/2 height baton round filler (environmental protection specialty conventional products, specific area is the bigger the better) every layer above filler, settle (the available pvc pipe fabrication and installation of alkali lye atomized spray rod, the gas outlet of Ф about 200mm is opened at top, spray wands is connected with alkali liquid tank, through high-pressure pump, alkali lye is sent into spray wands, alkali lye from tank body top toward current downflow, waste gas upwards flows, the two is reverse to improve exchange absorption efficiency, open circuit hole, air chamber top, alkali lye backflow after spray, recycle.Dry adsorption tanks grid plate is divided into five layers, and the CaO (quick lime) of 1/2 height is stacked in three layers, bottom, quick lime has two functions, 1) deodorizing and suction pernicious gas further; 2) waste gas humidity after spray is large, is in saturation state, absorbs moisture content in removing waste gas through CaO.Acticarbon is stacked on two layers, top.
After quick lime and active carbon all use breathable bag packaging (as sand bag-like) to run a period of time, CaO makes moist into pasty state, can take out change by bag.Active carbon runs a period of time changes protective gas Disposal quality when efficiency decline is also met an urgent need.
Ф 200mm blast pipe is installed at adsorption tanks top, and exhaust gas pipe height should meet environmental requirement, and installs thief hole on pipe, is convenient to environmental administration's sampling monitoring and self monitoring at ordinary times.
