Abstract
The invention discloses a discharge method of condensed water in the bottom of a fan volute casing. A trap is arranged on the bottom of the fan volute casing and used as a water seal; pressure from the height of the water seal is higher than wind pressure, so that the condensed water in the volute casing can discharge water automatically through the water seal, without gas mixing, and then the condensed water is refluxed and discharged along the inner wall of an aspiration duct. The discharge method has the advantages of reliable safety of the fan, reasonable, timely and convenient discharge of the condensed water. The discharge method not only avoids motor burnout due to that blades of the fan are hindered by the condensed water but also provides a discharge outlet of the condensed water.
Description
Technical field
The present invention relates to the discharge method of water in a kind of blower fan, particularly relate to a kind of discharge method of bottom condensate water in volute for fan.
Background technique
Upwards discharge in the process of gas (vapour) bodies such as steam, wet air or wet waste gas that produced on the pond (or waste liquid pool) or after shutting down at blower fan at present; gas (vapour) body is when temperature reduces gradually in blower fan and airduct; can produce condensed water; condensed water is stranded in blower fan inner spiral casing bottom; thereby flood impeller; at fan operation or when starting once more, cause because of the excessive accident of burning motor of impeller load.Therefore, condensed water is discharged outdoor at blower fan bottom standing meter waste pipe (band water seal).Discharge that outdoor condensed water not only will be considered to collect, reuse and water quality is to the problems such as influence of outdoor environment, also to consider in the process outside the discharge of the condensation water outlet in the workshop workshop, can be subjected to all multifactor influences such as workshop internal unit, pipeline, pipe trench, the discharge difficulty is bigger.
Summary of the invention
Technical problem to be solved by this invention provides a kind of discharge method of bottom condensate water in volute for fan, thus the reliably protecting blower fan, have the discharging condensed water rationally, in time, advantage easily.
The present invention realizes by following technological means:
A kind of discharge method of this bottom condensate water in volute for fan by in blower fan (1) spiral case bottom a trap being installed, is discharged the trap water outlet again.
The discharge method of described bottom condensate water in volute for fan, preferred technological means are that the pressure that forms of trap water seal height is greater than the blast in the blower fan.
A kind of discharge method of described bottom condensate water in volute for fan, preferred technological means can also be that the outlet that described trap water outlet is discharged is in the air intake pipe, the final backflow toward the pond.
Above-mentioned two kinds of preferred technological means can be used separately, also can be used in combination.
By a trap being installed in the volute of blower bottom, the pressure that keeps the formation of trap water seal height is greater than the blast in the blower fan, when gas such as steam, wet air or the wet waste gas that upwards discharges on pond or the waste liquid pool to be produced at blower fan or gas process produce condensed water, can and not collaborate by the automatic draining of water seal, again condensed water be refluxed toward the pond along the air intake pipe inwall.The present invention has the reliably protecting blower fan, the discharging condensed water rationally, in time, advantage easily.Both avoided causing the accident of burn-down of electric motor, solved the discharging outlet of condensed water again because of condensed water prevention fan blade.
Compare with the discharging of existing blower fan condensed water, the present invention have the discharging condensed water rationally, in time, advantage easily.And invest for a short time, transform simple.
Description of drawings
Fig. 1 is scheme of installation of the present invention.
Embodiment
In blower fan 1 spiral case bottom a trap 2 is installed earlier, the pressure that the trap water seal height forms is discharged into air intake pipe 3 with the trap water outlet again greater than the blast in the blower fan.When producing condensed water in the process of the gases such as steam, wet air or wet waste gas that blower fan upwards discharges on pond or the waste liquid pool to be produced, condensed water can and enter in the air intake pipe by the automatic draining of water seal, the final backflow toward the pond.Present embodiment can not cause from here collaborates, and has solved the discharging outlet of condensed water again.
Claims (3)
1, a kind of a kind of discharge method of bottom condensate water in volute for fan is characterized in that: in the volute of blower bottom trap is installed, the trap water outlet is discharged again.
2, the discharge method of the described bottom condensate water in volute for fan of claim 1 is characterized in that: the pressure that described trap water seal height forms is greater than the blast in the blower fan.
3, the discharge method of claim 1 or 2 described bottom condensate water in volute for fan is characterized in that: the outlet that described trap water outlet is discharged is in the air intake pipe, the final backflow toward the pond.
