Kind, can be effectively to the H in waste gas2S, the pollutant such as ammonia is caught and absorbed, while is also had and mended for microorganism growth
Fill nutrition and the effect of soda acid buffering.
Zinc cation spray equipment 5 and nutrient solution spray equipment 7 described in the utility model are by spray gun and connection spray gun
Nutrient solution circulation pipe 16 forms, and the setting quantity of spray gun is 4~6, and the nutrient solution circulation pipe 16 for connecting spray gun passes through nutrient solution
Circulating pump 14 is connected with liquid collecting aeration tank bottom.
Waste gas inlet 12 and exhaust outlet 8 described in the utility model are respectively equipped with air inlet gas detecting instrument 23 and air inlet
Gas detecting instrument 24；Temperature sensor, PH meters, nutrient solution concentration meter and firing equipment, biological mistake are provided with liquid collecting aeration tank 4
Temperature sensor, heater and humidity sensor are provided with filter packing layer 6, above-mentioned detection device, firing equipment and micro-
Nano-bubble generator 15, nutrient solution circulating pump 14 are connected by transmission line with automatic control system respectively, realize that automatic control is adjusted
Indices needed for section.
Automatic control system described in the utility model includes automatic control cabinet 17, and automatic control cabinet 17 is provided with humidity display
Table 18, temperature display watch 19, computer heating control switch 20, PH show that table 21, nutrient solution concentration show table 22.
The operation principle of the effective integrated biological deodorizing processing unit of the utility model is as follows：
During operation, waste gas first passes around waste gas inlet 2 and enters integral biological deodorizing tower 1, passes through the cloth of distribution device 3
Gas, spread from bottom to top in zinc cation system, cleaning solution is by zinc cation spray equipment 5 from top to bottom to easy in waste gas
Molten composition and particulate matter are absorbed and washed respectively, and the pollutant in waste gas enters liquid phase during gas-liquid contact,
Cleaning solution after washing enters liquid collecting aeration tank 4, and the waste gas after washing enters biological filter system.Into liquid collecting aeration tank
The foul smell composition that 4 cleaning solution carries is contacted with the microorganism being attached on biologic packing material 11, and foul smell is completed by biodegradation
Processing, during which aid in being aerated with micro-nano bubbler techniques.The waste gas for crossing zinc cation system contains less soluble composition into life
Thing filtration system, the biomembrane being attached on biofiltration filler 6, which is caught, to be absorbed, and is completed by biodegradation to foul smell
Processing.
During deodoration system is run, automatic control system is by importing and exporting waste gas air quantity, exhaust gas concentration, temperature, PH, circulation
The data analysis such as nutrient solution concentration and biofiltration moisture content carries out auto-control, to be optimal operating condition.For example,
When air inlet waste gas air quantity or concentration load become big, now inlet gas detector 23 is by the air quantity or concentration data of waste gas
Automatic system is transferred to, automatic control system can increase spray flux by analysis.For example, the optimum temperature of microorganism growth is 30
~35 DEG C, when temperature is less than 30 DEG C, data are passed to automatic control system by temperature sensor by transmission line, and system passes through fast
Speed analysis, assigns heating instructions to firing equipment, when temperature is more than 35 DEG C, is automatically stopped heating.For example, microorganism growth
Optimum PH is 7~8, when biological filter system pH value is super to go beyond the scope, can be sprayed by opening nutrient solution spray equipment 7
Recirculating nutrient solution buffers, and when the PH in liquid collecting aeration tank 4 is super to go beyond the scope, can add cushion by inlet 12
Matter.For example, when the nutrient concentrations that nutrient solution concentration detection meter is detected in recirculating nutrient solution are too low, transfer data to
Nutrient solution concentration in automatic control system shows table 22, and automatic control system is after analysis by automatically or manually adding
Nutritional ingredient.In another example the optimum humidity scope of biofiltration packing layer 6 is 40~60%, when biofiltration packing layer excessively
When drying, automatic control system passes through data analysis, opens nutrient solution spray equipment 7 and is humidified.
In addition, in system operation can according to the flexible operational outfit of waste gas payload, for example, when waste gas load it is small,
When concentration is low, micro-nano bubble aeration system or zinc cation system can be closed, biological filter system is only opened and can reach reason
Think treatment effect, fully demonstrate the system operation flexibility height of the utility model processing unit and handling process, and can be big
It is big to save operating cost.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.It should be pointed out that due to the finiteness of literal expression, and it is objective
On in the presence of unlimited concrete structure, for the utility model person of an ordinary skill in the technical field, do not departing from this
On the premise of utility model is conceived, some simple deduction or replace can also be made, should be all considered as belonging to of the present utility model
Protection domain.
