Description
Technical field
The present invention relates to two fluid spray systems, specifically relate to a kind of intelligent variable technique spraying system.
Background technology
Two fluid sprays are that it utilizes compressed air flow at high speed to make the operation principle of liquid particle, and the mist of generation gasifies by contacting to produce with external environment condition and body surface, are absorbed the effect arriving humidification and humidity improvement;
Two fluid sprays are mainly used in numerous industries such as weaving, cigarette, electronics, printing to be improved for space humidification, production line humidity, and the sprinkling, cooling down etc. of disinfectant, purposes widely.
But what existing two fluid spray systems all adopted metered dose mode (i.e. constant mist amount and mist footpath mode) to control to spray by traditional mechanical valve opening and closing opens, stops.Because the adjustment of gas circuit and fluid path all adopts manual adjustments, gas, liquid proportional cannot be adjusted fast, efficiently, accurately voluntarily, therefore the droplet and mist amount that adapt to current environment can not be ejected, when being subject to the factor such as outside gas, hydraulic pressure instability and affecting, easily cause droplet, mist amount unstable, injection fog precision is extremely low;
Owing to not possessing the function of frequency conversion feed flow and flow automatic regulation, therefore, rearrange liquids flow cannot be judged accurately, cause the flow accuracy spraying fog low, the spraying requirement under being therefore difficult to meet varying environment and under motor pattern.In addition, source of the gas does not have self-checking function cause source of the gas too much to waste, not energy-conservation, and there is no good control mode, occur shutting down rear or producing a large amount of dripping phenomenons before starting.
About the humid control precision of spraying humidification system, the moisture that adds within the scope of certain space obtains according to following formulae discovery usually: H=V × ρ × 1.2 × (X
2-X
1) ÷ 1000 × N × 1.2.In above-mentioned formula, H for needed for add moisture (kg/h), V is spatial volume (m
3), ρ is atmospheric density (kg/m
3), 1.2 is temperature coefficient, (X
2-X
1) adding moisture for every cubic metre, N is rate of ventilation, and 1.2 is loss factor.
Can draw from above-mentioned formula, when design humidity, usually with the water-retention value of worst air outside air, the water content of the needs after being heated up by new wind in air is for adding moisture, after the actual humidity value detected in spatial dimension when humidity sensor reaches default humidity value, control part branch closed control valve is to stop humidification; The actual humidity value detected in spatial dimension when humidity sensor is low after default humidity value, and control section reopens control valve to start humidification; Because moistness value range controls usually in 10%, and mist amount processed designs according to maximum humidification value, therefore, when opening when spraying, inertia due to humidification causes humidity to raise suddenly, humidity environment in spatial dimension is caused and sharply affects, mist amount and mist footpath can not be regulated in little error range to control to add moisture accurately, the Variable Control of degree of precision cannot be realized.
