Description of drawings
Fig. 1 is the structure chart of the small-sized cremate smoke eliminator of the utility model.
The specific embodiment
Below with reference to accompanying drawing and preferred embodiment technical solutions of the utility model are described in detail.
As shown in Figure 1, be the structure chart of the small-sized cremate smoke eliminator of the utility model.The structure of small-sized cremate smoke eliminator comprises: chemicals dosing plant, condenser pipe 1, depickling spiral nozzle 2, exchange caustic scrubber 3, dried drain separator 4, alkali lye generator 5, activated carbon eductor 6, sack cleaner 7, grey car 8, air-introduced machine 9 and filter screen 11.
Chemicals dosing plant connects exchange caustic scrubber 3 by pipeline, and condenser pipe 1, depickling spiral nozzle 2 and filter screen 11 are arranged on exchange caustic scrubber 3 inside, are followed successively by depickling spiral nozzle 2, filter screen 11 and condenser pipe 1 from top to bottom.Exchange caustic scrubber 3 is provided with smoke inlet and outlet, and outlet is connected to the inlet of dried drain separator 4.
Depickling spiral nozzle 2 connects chemicals dosing plant by pipeline, and chemicals dosing plant is used for providing alkali lye to depickling spiral nozzle 2.Exchange caustic scrubber 3 is used to remove acidity and the oily matter that enters flue gas as the deacidification structure, inner filter screen 11 forms water membrane under the spray function of depickling spiral nozzle 2, ash-laden gas is purified in the process by moisture film and atomizes, part sour gas that contains in the flue gas in this process such as HCL etc. are neutralized processing, have reduced the probability of dioxin regeneration.The volume of exchange caustic scrubber 3 is about 1.2m
3With quick lime solution is alkali lye, and the pH value of alkali lye generally is controlled in 8～9 scopes.It is raw material that exchange caustic scrubber 3 all adopts stainless steel, and the special anti-corrosion material of inner process is handled, and can effectively prevent the erosion of harmful substance, the service life of having improved equipment; Compare with traditional cooling measure such as wild wind of mixing, this method has characteristics such as the flue gas total amount is little, the operational outfit resistance is little, noise is low, and is shorter cool time than air heat exchange forced cooling method, and running resistance is little.
The cremation of remains flue gas is through the Cremation Machine main combustion chamber more than 850 ℃ behind the high-temp combustion, enter and fire the chamber again, fire room temperature again and should remain on about 850 ℃, gas residence time 〉=2s, and control certain oxygen content, this moment, various organic matters all decomposed, gas fume after burning is carried out chilling, and flowing through when high-temperature flue gas exchanges in the process of caustic scrubber 3, and it is lowered the temperature under the effect of cold water, make it rapidly cooling to below 200 ℃, cross dioxin-like chemical regeneration temperature district to greatest extent.Condenser pipe 1 is made of the long heat exchanger tube of 84 0.5m, and volume is 1.9m
3
In the utility model, depickling spiral nozzle 2 is placed the top of condenser pipe 1, purpose is the alkali lye that sprays through over-quenching flue gas later and 3 the stainless steel depickling spiral nozzles 2 that are arranged on exchange caustic scrubber 3 top diverse locations fully to be contacted in the mode of reverse flow and neutralization takes place, and to washing through the flue gas after the water-cooled, flue-gas temperature is reduced rapidly, promptly play flue gas cooling effect once more, also reach simultaneously and remove sour gas and the organic purpose of oiliness.
The outlet of dried drain separator 4 is provided with activated carbon eductor 6 by the inlet of pipeline connection sack cleaner 7 on pipeline.Enter dried drain separator 4 by nebulization channel after, through sufficient centrifugal motion, large quantity of moisture in the flue gas and particle are discharged under the effect of centrifugal force and gravity through the flue gas after 3 atomizings of exchange caustic scrubber.Realized the purpose of gas-water separation, alleviated operating pressure, improved the use effect next step treating apparatus.Dried drain separator 4 volumes are 1.5m
3The bottom of dried drain separator 4 is provided with alkali lye generator 5, and cooled water enters in the alkali lye generator 5 once more through return line, measures in the using water wisely greatly.
Activated carbon eductor 6 can carry out drying to a little moisture in the flue gas after overdrying drain separator 4 centrifugal actions, and the while can effectively be adsorbed the dioxin of gas suspension in the flue gas and be contained the material of peculiar smell.The emitted dose of activated carbon eductor 6 is controlled at 100～150g/h.
Grey car 8 is installed in the lower end of sack cleaner 7, and outlet is provided with air-introduced machine 9.Sack cleaner 7 is according to the particularity of cremate process, as discharge the technical parameter such as the pressure loss, filter area of the exhaust gas volumn of characteristic, the processing of flue gas, suitable filtrate, permission, the version of filter bag is selected the circle bag for use, filter type is an outside filtering type, filter bag is the glass fibre filtrate, adopts the bottom inflow mode.Sack cleaner 7 is provided with automatic ash removing device, and automatic ash removing device can produce the high-voltage pulse air-flow, filters the flue dust that gets off with the winding-up filter bag.The filtration gas speed of sack cleaner is 2.5m/min, 24 of filter bags, every filter area 0.82m
2
The cremate flue gas enters from bottom to top from the smoke inlet on exchange caustic scrubber 3 right sides, and under the effect of condenser pipe 1, the cigarette temperature reduces rapidly.Then, depickling spiral nozzle 2 spray alkali lye, under the effect of filter screen 11, flue gas mixes fully with the akaline liquid of atomizing, and acidity in the flue gas and oily matter are realized removing.Then, flue gas enters dried drain separator 4, under the effect of dried drain separator 4, flue gas is done wet the separation, and gas rotates into sack cleaner 7, and liquid flows under the influence of gravity into the alkali lye generator 5 of sack cleaner 7 bottoms, activated carbon eductor 6 is installed before the sack cleaner 7, in the running, according to the actual requirements, reasonably add activated carbon powder by the hopper in the activated carbon eductor 6.Flue dust and activated carbon powder through the pulse blowback are slipped in the grey car 8, are convenient to concentrate cleaning.Cremate flue gas after the purification enters chimney 10, then emptying under the effect of air-introduced machine 9.
