Description
Technical field
The utility model especially is used to get rid of indoor poisonous and harmful dusty gas relevant for a kind of relevant for a kind of airhandling equipment, and sends into the fresh air ventilator of outdoor new wind.
Background technology
In industrial enterprise, the especially petrochemical enterprise, the corrosive gas in the atmospheric environment is more, and can discharge in production in many rooms or the storage process or may discharge poisonous, flavor, explosion hazard gas arranged.In order to prevent that pernicious gas from gathering, guarantee safety in production, according to technological requirement, these rooms have the above continuous ventilating of 6 times/h usually.In can holding chamber during draughty environment, the explosive-proof grade of process equipment even can reduce a safe class in the room sometimes, thus reduce the investment of process equipment significantly.In most of the cases, the mode of mechanical exhaust is adopted in the continuous ventilating in the industrial enterprise.Northern area in the winter time, this class room of the overwhelming majority requires indoor temperature to maintain 5～10 ° of C again.
At present, for this class room several typical ventilation schemes are arranged:
1, only establish the axial flow exhaust blower, do not establish benefit wind, mend wind entirely by the slit infiltration by door and window, the indoor heating system that is provided with is kept indoor temperature.The problem that this scheme exists is: because the seal of door and window is become better and better now, when winter, door and window was closed, the blast that the axial flow exhaust blower can provide is very limited, can't permeate air quantity by the door and window slit up to 6 times/h rate of ventilation at all, in fact can't keep draughty indoor environment, have certain security risk.
2, the axial flow exhaust blower is set, the natural air inlet mouth is set simultaneously, indoor heating system and the warm-air drier of being provided with is to keep indoor temperature.The problem that this scheme exists is: the temperature difference between air draft and the new wind is bigger, causes a large amount of air draft heat loss; In addition, winter, indoor temperature was inhomogeneous, and near the temperature the air inlet is very low, near the suitable scope the air intake fluerics, can not be furnished with the equipment or the pipeline of antifreeze requirement; Have, warm-air drier needs independent heat supply pipeline again, and system is comparatively complicated.
3, the axial flow exhaust blower is set and carries out air draft, the indoor heating system that is provided with is provided with machinery simultaneously and mends wind, and with new wind be heated to send into after the indoor temperature indoor to keep indoor temperature.The problem that this scheme exists is: because the temperature between air draft and the new wind is bigger, cause a large amount of air draft heat loss; In addition, new wind heating needs independent heat supply pipeline, and the anti-frost protection measure need be set, and prevents that in particular cases heat(ing) coil is by bursting by freezing, and system is comparatively complicated.
And existing common ventilator, the heat exchanger anticorrosive property is poor, and has cross pollution between new wind and the air draft, and the gas or discharge in the environment of dangerous gas of being not suitable for being corrosive in industrial enterprise uses.
Therefore, be necessary to provide a kind of novel ventilator, overcome above-mentioned defective.
The utility model content
