1. Supply of odors, emissions manufacturing for animal feed

Every animal feed manufacturing facility has totally different scale and manufacturing processes. Beneath is a course of of manufacturing animal feed on the manufacturing facility specializing within the manufacturing of animal feed for pigs (piglets, tremendous lean pigs, sows), cows (dairy cows, beef beef), hen (white hen. , tremendous meat hen, tremendous egg -layer), geese (geese, geese laying tremendous eggs), goose, quail, … with a complete capability of 24,000 tons/12 months.

Manufacturing course of: Loading uncooked supplies, crushing> positive crushing> positive crushing> squeezing, reducing items> packing

On this manufacturing course of, phases akin to drying, urgent, extruding, cooling because of the results of excessive temperature uncooked materials will generate a typical scent of animal feed, primarily the scent of compounds Natural and a small quantity of mud are collected from the manufacturing line by way of exhaust fan.

These smells at excessive concentrations will trigger discomfort to people. Apart from, the manufacturing supplies akin to fish powder, fish fats, meat powder, … additionally trigger disagreeable odors.

Based mostly on the precise manufacturing of animal feed at every manufacturing facility, the method of loading, grinding, mixing and packaging typically generates a quantity of uncooked mud. If there is no such thing as a management measure, this quantity of mud will immediately have an effect on employees working within the above phases, inflicting respiratory illnesses.

As well as, throughout the operation of the plant, it’s inevitable that the gases arising as a result of biodegradable processes from uncooked supplies and strong waste piles. These gases typically comprise components H2S, CH4, Mercaptan, … creating a really disagreeable stench.

There may be additionally a boiler emissions containing polluting elements akin to CO, NO, SO2 and dirt.

2. Confer with the scent therapy system for animal feed manufacturing

Mud and emissions generated principally on the phases within the manufacturing course of. With a purpose to reduce the environmental impression, the manufacturing facility proprietor wants to rearrange suction, suction pipes and dirt restoration synchronously with the manufacturing line.

2.1. System of scent, mud and emissions therapy throughout manufacturing

The processing course of takes place as follows:

Odor, mud, emissions> suction/suction chamber> exhaust fan + Pipeline> Cloth mud filter tools> Energetic carbon adsorbing tools> exhaust fan> Surroundings (emissions achieved QCVN 19: 2009/ BTNMT, column b)

Processing course of

– Vacuum vacuum: The mud is collected on the arising place by means of the suction capturing organized on the instruments.

– Cloth mud filter tools:

• The suction shoots are related to the pipeline system, underneath the impact of centrifugal suction, mud in response to the pipeline system by means of the filter of the material bag.
• The air and dirt passing by means of the filter material, initially, the mud particles are bigger than the slot between the materials that shall be stored on the floor of the material in response to the precept of a sieve, the smaller particles adhesion on the floor of the filter material because of the collision , gravity and electrostatic attraction, regularly the collected mud is thickened to type a filtering membrane to 99.8% and filter all very small particles because of the filtering assist layer.
• The mud is collected from the recalled manufacturing course of to return to the manufacturing line as a result of it is a mud.
• After a interval of operation, the mud layer will thicken and make the obstacles of the membrane too giant. Due to this fact, it’s essential to cease the emissions passing and proceed to take away the mud layer on the material floor (that is referred to as the filtrable skill).
• 2-3 years periodically, fabric baggage must be changed with new baggage to make sure mud filtration effectivity.

– Adsorption tower by activated carbon: The ambiance continues because of the impact of the centrifugal exhaust fan to create the stress to push the air to the adsorbent tower by activated carbon. On the tower of adsorbing by activated carbon, the emissions will transfer into the tower from the underside of the tower and thru the activated carbon filter layers and are adsorbed by the activated carbon filter layers. Substitute the activated carbon layer within the tower to make sure dealing with effectivity.

– East emissions after therapy: Clear air after adsorbing the scent and vapor poisonous fuel, assembly the prescribed requirements, it’s escaped out of the atmosphere by means of the exhaust pipe output.

2.2. System of boiler emissions therapy

Along with emissions, mud, odors from the manufacturing course of, the manufacturing facility additionally has boiler emissions. For this emissions, the plant is handled by putting in mud cyclone tools mixed with emissions therapy system.

The processing course of takes place as follows:

Excitation fuel emissions> Heating units> exhaust fan> Cyclon separating mud> exhaust fan> Absorption tower> exhaust tube> Surroundings (emissions achieved QCVN 19: 2009/BTNMT, column b)

Course of clarification

– Heating equipment: From the boiler out of the mud and poisonous emissions akin to CO, SO2, NO2 and excessive temperatures. The emissions shall be led to the heating equipment, the place the temperature of the emissions shall be cooled and dropped considerably.

– Xyclon separating tools: Then exhaust fuel is pushed into the mud separating the mud right here because of the impact of the centrifugal drive of the exhaust fan and the gravity of the mud is discovered within the emissions, the quantity of dry mud is retained within the mud settlement chamber.

– Absorption tower: After passing the dusty cyclon, the exhaust fuel is pushed into the absorption machine to make use of clear water periodically with lime milk. The emissions are pushed from the underside of the tower absorbed up, and the clear water is pumped from the highest of the tower absorbed down. The air circulation temperature right here is considerably decreased, a part of the mud is retained and on the similar time the contact between two phases and liquid, the fuel parts SO2, NO2, CO, … are molecules with The acidity shall be absorbed from the fuel section into the liquid section. Because of this course of, the remaining mud and poisonous gases shall be separated from the fuel section.

– East emissions after therapy: Making certain sensory high quality (smoke is not black) to make sure the allowable restrict in response to QCVN 19: 2009/BTNMT, column B. Mud and sediment from the tank of absorbing answer are periodically collected and picked up and Hiring transportation in response to the rules on strong waste administration.

3. Plan for testing and testing the scent processing system

Along with set up emissions therapy system In accordance with the capability within the environmental data, companies ought to take note of the operation of the system after being granted environmental licenses. Beneath is a reference desk for testing the scent processing system of the animal feed manufacturing facility.
