The purpose of formaldehyde during the cooperation of the utility model by the spray system and the gas system for the distribution of commodities reaches and purify air, its purification process is: the air that contains formaldehyde enters in the casing by the air inlet and the air blast of gas communication system; Enter microbial nutrient solution, inoculation that the air that contains formaldehyde in the casing passes spray system successively have can the packing layer of oxidation Decomposition formaldehyde microorganism after, discharge from the exhaust outlet of gas communication system; The air formaldehyde that it contains in the process of circulation can pass through the biochemical degradation effect of absorption, absorption and the microorganism of microbial nutrition liquid layer, packing layer, finally is decomposed into nontoxic water and carbon dioxide, thereby reaches the purpose that purifies formaldehyde.

Adopt the beneficial effect that technique scheme produced to be: the utility model utilizes microbial action to purify formaldehyde, can not produce secondary pollution, and this device has less energy consumption, operating cost is low, handles large-mindedly, and purification rate is fast, outstanding advantages such as equipment volume is little, and cost is low.The utility model is simple in structure, and is easy to use, not only can purify formaldehyde effectively in a large number, and can also remove harmful substances such as benzene, toluene.The utility model is suitable for some house and the chemical plant of just having fitted up or just having acquired new furniture, and effective purification formaldehyde is played in the too high places of air content of formaldehyde such as furniture market, ensures the effect of health of people.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of air inlet pipe in the utility model.

The specific embodiment

This formaldehyde biological cleaning device includes casing, spray system and the gas system for the distribution of commodities.
