Description
Technical field
The utility model relates to a kind of discharge means, relates in particular to a kind of discharge means for pipeline.
Background technique
The industrial cycle water system can be divided into two kinds, and a kind of is closed circulating water system and open type circulation.In the open type circulation, when cooled backwater was back to the draining collector, water can enter the draining collector with the air that is mingled with in a large number; Though be provided with tube exhaust valve on water return pipeline, in actual use, existing tube exhaust valve can't satisfy the demand of pipeline exhaust at all.The backwater that contains aqueous vapor not only can damage the filler of cooling tower, thereby influences the intensity of cooling of normal state; Also can make circulation the excessive situation of backwater occur, so just can not satisfy the requirement of the clean environment firendly of produced on-site.
Be that example is illustrated with one group of direct sending pump parameter in the clear recirculating cooling water system:
Former 2 usefulness 2 that are designed to of conveying pump group are equipped with, and send water flow 74m
3/ min, 85 meters of lifts.After the dilatation of main body production output increased, this recirculating cooling water system load also had increase, and the method for operation of conveying pump group changes 3 usefulness 1 fully into by 2 original usefulness 2 and is equipped with the specified water flow 110m that send
3/ min, lift still are 85 meters.Be accompanied by the increase of water yield load in the recirculating cooling water system 11, the water body in the system flows along the P direction, and the phenomenon of intermittent circling water flow rate moment amplification also can take place backwater, and the endurance is between 65 seconds to 75 seconds; Though the endurance is of short duration, but can cause water return pipeline relief opening 12 that intermittent mouth of pipe spilling water phenomenon takes place, backwater overflows from relief opening 12, has represented the state that backwater overflows along the continuous arrow of Q and Q ' direction, the endurance of overflowing is about 60 seconds, as shown in Figure 1.
When the intermittent circling water flow rate of system amplifies, its moment circling water flow rate will reach 115m
3/ min, backwater lift 35m, endurance 65-75s.Water return pipeline DN1200, return pipe overhead height are 12m, and the relief opening height is 0.8m; The normality flow is that rated flow is 110m
3/ min, backwater lift are 27m.
By endurance 60s(1min) criterion calculation:
(moment flow-normality flow) * time * (unusual backwater lift-normal backwater lift) * damping constant=spillway discharge is brought above-mentioned numerical value in the formula that calculates spillway discharge into, obtains (115-110) * (35-27) * 1*0.051=2.4m
3, that is to say that each this pump group circling water flow rate amplifies, with endurance 60s(1min) and standard calculates, and the backwater spillway discharge of water return pipeline relief opening is 2.4m in the recirculating cooling water system
3
This shows, when the increase of water yield load in the recirculating cooling water system, the backwater spillway discharge of water return pipeline relief opening has increase, overflow from relief opening in a large number, not only cause the waste of industrial water resource, influence the working environment of produced on-site, also can the filler of cooling tower be caused damage, reduce Security and the stability of the operation of recirculating cooling water system equipment, thereby, need to reduce and avoid backwater that a large amount of excessive phenomenons take place as far as possible.
The model utility content
The purpose of this utility model provides a kind of steam segregating unit, and this steam segregating unit not only can reduce the overflow water yield when exhaust process in the recirculating cooling water system, avoids excessive backwater to cause the environmental protection influence; Can also get rid of residual gas in system pipeline, thereby reduce the damage that backwater steam causes cooling tower filler effectively, the working life of improving cooling tower filler.
To achieve these goals, the utility model provides a kind of steam segregating unit, and it comprises:
One body;
At least three group resistance stroke plates are fixed in the described body in parallel to each other, and equate along the described spacing of respectively organizing between the resistance stroke plate of the axial direction of body; The described resistance stroke plate of respectively organizing includes: a mainboard and a subplate, and the alternately setting relative with subplate of described mainboard, described mainboard and subplate all tilt towards the direction that the adverse current body flows, wherein has one first angle α between mainboard and the inboard wall of tube body, have one second angle β between subplate and the inboard wall of tube body, the acute angle angle between mainboard and the subplate is γ.
Steam segregating unit described in the utility model, have at least three group resistance stroke plates at body, wherein every group of resistance stroke plate all comprises a mainboard and a subplate, in the time of in backwater enters body, can be subjected to stopping of mainboard and subplate, simultaneously again because the relative setting alternately with subplate of mainboard and mainboard and subplate are non-intersect separated by a distance, backwater can be directly straight through inboard wall of tube body like this, need from the staggered gap of mainboard and subplate, pass through, thus the flowing velocity of having slowed down backwater.Formed acute angle angle between each mainboard that the direction that flows towards the adverse current body is obliquely installed and each subplate, not only reduce the rate of climb of backwater water body in body to slow down the flowing velocity of backwater in the unit time further, also changed the ascent direction of backwater water body.The setting of three groups of resistance stroke plates can make backwater water body reciprocal three times and angle by resistance stroke plate in body, can not only effectively a large amount of air that are mingled with in the backwater be got rid of, to eliminate steam that the later stage forms to the damage of filler, can also control the rising flow of backwater water body, thereby reduce the overflow water yield of backwater.In process of production, can according to the actual requirements more groups resistance stroke plate be set in body, make water body in body, carry out repeatedly back and forth to reduce the backwater rising further and to reduce moisture content.
Further, mainboard and the subplate in the steam segregating unit described in the utility model is circular plate.
Further, the diameter of the mainboard in the steam segregating unit described in the utility model is 0.283-4m.
