Description

Odor removal

Technical field

The utility model relates to a kind of odor removal, especially a kind of odor removal for odor purification.

Background technology

Enhancing along with growth in the living standard and Public Environmental Awareness; the air environmental pollution problem is just causing increasing public attention; for preventing and avoid air environmental pollution; protection and the human living environment of improvement; country has formulated such as " The Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution ", " emission standard for odor pollutants ", " discharge standard of air pollutants ", " urban wastewater treatment firm pollutant emission standard " etc. relevant laws and regulations; therefore; the control atmosphere polluting problem can not be ignored, and air environmental pollution must effectively be solved.

The utility model content

In order to overcome the problems referred to above, the utility model provides a kind of odor removal, and this device reaches more than 10 years service life, can be in outdoor 0 ℃～40 ℃ scope normal operation.Can year-round operation, move continuously 24 hours every day, do not produce secondary pollution in its processing procedure.And this floor space is little, does not waste land resource.

The utility model solves its technical problem by the following technical solutions, the utility model by biology wash pretreating device, biofiltration device, accident and emergency treatment device, four device units of automaton form.

Its accident and emergency treatment device are to compile expanding reach at blower fan import airduct some atomizers are installed.

Automaton is comprised of blower fan, fluid level controller, make-up pump, PH controller, washing water tank, washing water tank.

The beneficial effects of the utility model are: efficiently biology washing humidification pretreating device, and cleaning solution regularly replenishes, recycles, and efficient is high, expense is low, anti impulsion load is strong; EGR is furnished with private filter, the circulation solution of biological washing humidifying unit can be filtered, and prevents the obstruction of EGR, the long-term stability operation of ensuring equipment; Device disposes emergency treatment device, can guarantee to eliminate to greatest extent under accident or emergency rating the impact on surrounding environment; Control device is reliable and stable, can all arrange manually each control device, automatic control, long-range multiple control modes, need not personnel are on duty guards, and realizes automatic operation, reduces running cost.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of odor removal.

1. biological washing pretreating device, 2. biofiltration device, 3. accident and emergency treatment device, 4. atomizers among the figure, 5. automaton, 6. blower fan, 7. foul smell, 8. fluid level controller, 9. make-up pump, 10.PH controller, 11. washing water tanks, 12. washing water tanks.

The specific embodiment

As shown in Figure 1, biological washing pretreating device (1) is the important process unit of odor removal, characteristics according to the waste gas generation, make the efficient activity of biologic packing material maintenance in the biofiltration tower, certain moisture requirement is arranged itself, gas relative humidity generally is not less than 98%, for satisfying the humidity requirement of biological filter deodorizing device, prevent gas filler self water loss by filter bed the time, need to carry out humidification to gas and process, with the humidity of accurate control gas.According to matching requirements, make gas humidity remain on setting range.

The core of odor removal is biofiltration device (2), be conducive to biology and echo filler and the effectively compound microbial bacterial classification that growth is adhered to, make compound give birth to microorganism in the filter tower under the adapt circumstance condition, form biomembrane at the organic-biological filling surface, microorganism in the biomembrane utilizes inorganic and organic matter in the waste gas as carbon source and the energy, keep its vital movement by the degraded odorant, and the odor pollution material is converted to carbon dioxide, water and mineral matter etc.

For the stably reaching standard that guarantees odor removal discharges and is debugging, accident, emergency processing when biofilter maintenance or replacing filler, AKL-SW biofiltration purifier back segment is provided with efficient accident and emergency treatment device (3), its mode is installed some atomizers (4) for compiling expanding reach at blower fan import airduct, with a cover ECOLO-EP type atomized spray odor removal with special-purpose peculiar smell purify behind the working solution high-pressure atomization with pipeline in gas with foreign flavor fully mix, eliminate to greatest extent peculiar smell, work as device debugging, the appearance accident, when biofilter maintenance and foul smell discharging surpass setup parameter, emergency treatment device starts automatically, ECOLO-EP materialization flusher fully atomizes working solution by the high pressure sliding vane rotary pump, mix with ducted gas uniform, fully the deodorizing working solution fine droplet surface of atomizing has formed great surface energy.The peculiar smell molecules such as the ammonia of this surface energy in can adsorbed gas, hydrogen sulfide, and the peculiar smell molecular structures is changed, become unstable; At this moment, the effective molecule in the solution can provide electronics to the peculiar smell molecule, reacts with the peculiar smell molecule; Simultaneously, the peculiar smell molecule that is adsorbed on the drop surface also can with gas in oxygen react.Through the effect of working solution, the peculiar smell molecule will be adsorbed, decompose, thereby reach the purpose that peculiar smell purifies.

Automaton is realized automatic operation, need not personnel keep an eye at ordinary times.Automaton (5) the major control factor and control logic thereof:

The blower fan (6) of bleeding configuration frequency converter, by regulating the frequency of fan frequency converter, rotating speed and the exhausting amount of control blower fan when guaranteeing that foul smell (7) generation unit is in negative-pressure operation, reduce energy consumption to greatest extent.

Pretreating device tower body bottom is held the liquid section fluid level controller (8) is installed, control pretreating device tower body bottom liquid level, when liquid level is lower than the setting liquid level, make-up pump (9) starts voluntarily and adds to the setting liquid level, when overtime can't replenish, the device continuous alarm guarantees that EGR normally moves.

Pretreating device tower body bottom is held the liquid section PH controller (10) is installed, the PH that makes pretreating device tower body bottom hold the liquid section remains on certain limit, make-up pump starts voluntarily when being lower than setting value, in time the cleaning solution in the additional washing water tank (11) and the water in the washing water tank (12) guarantee the biological clean-up effect that washs the humidification pretreating device.

Enter installing gas temperature, humidity tester on the pipeline of biofilter at pretreating device, according to gas temperature, humidity measurement data, regulate washing intensity, guarantee to enter the gas humidity of biofilter at optimum range, thereby, ensure the stable operation of biofilter.
