In order to better enable the mixed solution of formic acid and calcium lignosulphonate to meet the requirement of disinfection spraying, the rated flow T1 of the first water pump is 60-125L/min; in order to timely and repeatedly flow the mixed disinfectant solution back into the disinfectant solution tank, the rated flow T2 of the second water pump is 48-86L/min.
In order to timely convey the mixed liquid to the spray head to meet the requirement of disinfection on the mixed liquid, timely enable the mixed liquid to flow back into the disinfectant tank again to be recycled, and fully exert the working capacity of the second water pump (the overlarge flow index requires that the water pump has larger power, and when the rated flow is larger than the actually required flow, the waste of electric energy is caused), the flow of the second water pump is 68% -80% of the flow of the first water pump.
In order to realize uniform spraying during disinfection and achieve the best disinfection effect, circular spray holes are uniformly distributed on the spraying surface of the spray head, the diameter D1 of each spray hole is 0.32-1.68mm, and the density M1 of the spray holes is 59-458/square centimeter.
In order to achieve better spraying effect and improve disinfection capacity of the spray head, the rated flow T1 of the first water pump, the diameter D1 of spray holes and the density M1 of the spray holes satisfy the following relations:
in the above formula, λ is the flow coefficient of the first water pump, and the value range is 1.67-17.2; in the above formula, only numerical operations are performed, and no unit operations are performed.
In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "disposed," "connected," "secured," "inserted," and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
