Description
Technical field
The utility model relates to the exhaust gas processing device technical field, particularly a kind of being used for drying the vent gas treatment wash mill that the high wet acidic tail gas of stove peculiar smell is handled.
Background technology
Rotary furnace kiln drying technology obtains widely applying in each relevant industries such as cement, feed, composite fertilizer.The high wet acidic tail gas of oven dry wherein often only just directly enters atmosphere through simple process; contain a large amount of harmful substances in the tail gas; environment has been caused severe contamination, and along with to the environmental protection pay attention to day by day, instant stage has been arrived in the improvement of drying oven kiln exhaust gas.
Making in the process of feed of alcohol slag, vinasse oven dry, and in the process of high concentrated organic wastewater production composite fertilizer, the drying oven kiln exhaust gas is the high humidity acid waste gas of dried material discharge and the mixture of coal-fired flue-gas, contain a large amount of harmful substances, in present existing smoke gas treatment method, efficient is poor, and investment is big, and method that can harmless treatment does not also almost have.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome above-mentioned technical problem, provides a kind of vent gas treatment wash mill, can realize the thorough harmless treatment of high humidity acidic smell waste gas in the oven dry stove, and the treatment effeciency height, simple to operate.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of vent gas treatment wash mill, comprise the fine purifiation pond of independent closure designs respectively, biological bed, the automatic operation controller of blower fan power set and PLC, bottom, side, fine purifiation pond has an exhaust gas inlet, fine purifiation pond top exit is communicated with biological bed by pipeline, biological bed is terminal to be communicated with the blower fan power set by pipeline, blower fan power set top has a clean gas outlet, also be fitted with circulating sprayer and chemicals dosing plant on the fine purifiation pond, the automatic operation controller of PLC is by following the tracks of the start and stop that detect circulation fluid and then control chemicals dosing plant.
Circulating sprayer and chemicals dosing plant all are communicated with by the top of same carrier pipe with the fine purifiation pond, circulated sprinkling water in the circulated sprinkling system and the chemical agent in the chemicals dosing plant are mixed into circulated sprinkling liquid and from top to bottom spray like this, be convenient to technology waste gas and fully contact, make purification more thorough with circulated sprinkling liquid.
The filler of biological bed is natural organic filler.
The beneficial effects of the utility model are: this device can thoroughly be removed the peculiar smell of oven dry stove high humidity acid waste gas, and the treatment effeciency height is handled final vacuum and met national GB14554-93 " odorant pollutant discharge standard " related request; The cost performance height, having plurality of specifications equipment can be for selecting for use targetedly; Fully automatic operation, convenient operating maintenance is simple; Long service life, once dropping into can be benefited for a long time.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing.The utility model is described further.
As shown in Figure 1, a kind of vent gas treatment wash mill, comprise the fine purifiation pond 1 of independent closure designs respectively, biological bed 2, the automatic operation controller 4 of blower fan power set 3 and PLC, bottom, 1 side, fine purifiation pond has an exhaust gas inlet 7, fine purifiation pond 1 top exit is communicated with biological bed 2 by pipeline, biological bed 2 ends are communicated with blower fan power set 3 by pipeline, blower fan power set 3 tops have a clean gas outlet 8, be fitted with circulating sprayer 5 and chemicals dosing plant 6 on the fine purifiation pond 1, circulating sprayer 5 and chemicals dosing plant 6 all are communicated with by the top of same carrier pipe with fine purifiation pond 1, and the automatic operation controller 4 of PLC is by following the tracks of the start and stop that detect circulation fluid and then control chemicals dosing plant 6.
In the vent gas treatment wash mill, fine purifiation pond 1 and biological bed 2 are formed the wash mill of this device, the absorption of the high wet acidic tail gas that produces when being used for whitewashing oven dry particle manufacture composite fertilizer.High wet acidic tail gas (being negative-pressure operation) under the suction of blower fan power set 3 is introduced into fine purifiation pond 1 and biological bed 2 through piping, in wash mill, industrial waste gas fully contacts with the circulated sprinkling water that top-down circulating sprayer 5 sends, smell substance is transferred to liquid phase from gas phase, the floating dust that waste gas carries is also cleaned simultaneously, thereby realizes the purification to waste gas.Xi Di carrying out thereupon, the circulated sprinkling water that circulating sprayer 5 sends can reach capacity to the solubility of smell substance, need this moment chemicals dosing plant 6 to add corresponding chemical agent, recover the solvability of circulation fluid smell substance to smell substance neutralization in the circulation fluid.
N-process is to follow the tracks of by the accurate detector device in the automatic operation controller 4 of PLC to detect the circulation fluid realization, when the chemical property that detects circulation fluid departs from setting value, the automatic operation controller 4 indication chemicals dosing plants 6 of PLC start, indication chemicals dosing plant 6 stops when reaching setting value, this process is gone round and begun again, thereby realizes the lasting purification to peculiar smell waste gas.
Biological bed 2 fillers are natural organic filler, help degraded to absorb smell substance.
Fine purifiation pond 1 and biological bed 2 specifically can carry out the difference design according to the good concentration of smell component, do not select for use biological bed 2 get final product when the concentration of waste gas is high, when the smell component complexity of waste gas, fine purifiation pond 1 and biological 2 use of can connecting simultaneously when concentration is higher.
As the case may be, also the control centre that particle manufacture composite fertilizer production line is dried in automatic operation controller 4 of PLC and whitewashing can be formed a whole, with the operational management efficient of further raising user to this vent gas treatment wash mill.
