Description
Technical field
The present invention relates to waste heat boiler technical field of structures, specially a kind of horizontal type waste heat boiler hydrophobic structure.
Background technology
Horizontal type waste heat boiler own characteristic, the hydrophobic main pipe of waste heat boiler is close from the ground, hydrophobic main pipe ratio and blowdown dilatancy
The interface of device connection is low, if blowdown system arrangement is on the ground, in waste heat boiler cold start, due to not having in boiler
There is pressure, the condensed water that can not be thinning out in superheater and reheater, be thus unable to unit normal operation safety.To ensure waste heat
Can be hydrophobic unobstructed during boiler startup, blowdown system can only be arranged in the hole of below ground, while to ensure blowdown dilatancy
The water of overflow can drain in device, it is necessary to dredge pump is equipped with, as shown in figure 1,1 be hydrophobic main pipe in figure, 2 be blowdown system, and 3
It is dredge pump for overflow pipe, 4.It is this by the way of arrangement blowdown system in hole, system complex, construction investment cost are high.
The content of the invention
It is complicated for said structure, the problem of cost is high, the invention provides a kind of horizontal type waste heat boiler hydrophobic structure, its
Simple in construction, cost is low.
Its technical scheme is such：A kind of horizontal type waste heat boiler hydrophobic structure, it includes blowdown system, the blowdown
Water inlet, delivery port and overfall are provided with flash vessel, the overfall connects row with the delivery port by outlet pipe
Dirty cooling bay, the water inlet are hydrophobic by hydrophobic main pipe connection boiler, it is characterised in that the blowdown system is arranged in ground
More than face, drain port is offered at the low level of the hydrophobic main pipe, blow-off pipe is installed at the drain port, on the blow-off pipe
The outlet for being provided with control valve and the blow-off pipe corresponds to trench arrangement.
It is further characterized by, and the control valve is motor-driven valve.
After structure using the present invention, drain port is provided with the low level of hydrophobic main pipe, when boiler cold-state starts, only
Motor-driven valve need to be opened, the condensed water in superheater and reheater is dredged in trench, so that it may ensure the normal operation safety of unit,
Blowdown system is arranged in more than ground, avoids the labyrinth of arrangement in hole, its is simple in construction, and cost is low.
Brief description of the drawings
Fig. 1 is prior art construction schematic diagram；
Fig. 2 is schematic structural view of the invention.
Embodiment
See Fig. 1, shown in Fig. 2, a kind of horizontal type waste heat boiler hydrophobic structure, it includes blowdown system 2, blowdown system 2
On be provided with water inlet, delivery port and overfall, overfall connects blowdown cooling bay 5 with delivery port by outlet pipe 3, water inlet
Mouth connects boiler hydrophobic 6 by hydrophobic main pipe 1, and blowdown system 2 is arranged in more than ground, is opened up at the low level of hydrophobic main pipe 1
There is drain port, drain port goes out to be provided with blow-off pipe 7, and the outlet that control valve 8 and blow-off pipe 7 are provided with blow-off pipe 7 corresponds to trench 9
Arrangement.Control valve 8 is motor-driven valve, is convenient to control.Overall cost of investment is low.10 be draining valve in figure.
Claims (2)
