Description
Technical field
A kind of boiler matching device is the utility model is related to, more particularly, to a kind of closed condensate recovery device.
Background technology
In steam indirectly heat system, as steam discharges the latent heat of vaporization in firing equipment, substantial amounts of high temperature condenses
Water produces therewith, and for its temperature typically more than 100 DEG C, heat content accounts for 25 % of original steam heat content or so, has very high exploitation value
Value, water quality are bordering on distilled water, are good boiler feedwaters almost without gases such as dissolving oxygen and carbon dioxides.So fully
Reclaim and can both save boiler oil and softened water using these condensates, the operating cost of boiler can be substantially reduced again,
Boiler service life is improved, improves environmental condition.
The condensate retracting device used now is mostly open type, many drawbacks be present：Open-type condensate tank have steam drain with it is big
Gas directly communicates, and condensate will produce a large amount of secondary flash vapour after entering water tank because pressure declines, due to the latent heat of vaporization
In the presence of secondary vapour carries a large amount of high-quality heat energies and is discharged in air, condensing water temperature is declined rapidly, causes mass energy and water
The wasting of resources, so a large amount of discharge of steam not only influence flat image into air, can also cause thermal pollution；It is placed on underground
Room, it can not more can dispose.
Open-type condensate tank leads directly to air, the condensate of deoxygenation originally can dissolved oxygen again, not only make water tank and condensate
Pipeline reduction of service life because of oxygen corrosion, it can also increase deoxygenation cost.
Utility model content
The utility model provides a kind of closed condensate recovery device, solves the Utilizing question of recirculated water, its technology
Scheme is as described below：
A kind of closed condensate recovery device, including a collecting container, the top of the collecting container are provided with spiral
Coil pipe, middle part are provided with steam-water separation condenser, and bottom is provided with water storage device, and the water storage device passes through pipe valve and electric-motor pump
Connection, the bottom of the water storage device are provided with sewage draining exit, and liquid level sensor is provided with the water storage device, and the liquid level passes
Sensor is connected with electric-motor pump, for providing enabling signal and stop signal.
The liquid level sensor is provided with two groups up and down.
Pressure gauge is set on the collecting container, for monitoring collecting container pressure inside the tank, when high temperature in collecting container tank
When water pressure exceeds safe pressure, the safety valve that collecting container is set is opened, the steam in tank is discharged to and is provided with expansion joint
Relay pipe, the other end of the relay pipe are connected to spiral coil.
The collecting container is connected with water replanishing device.
The steam-water separation condenser is multiaperture-type water separator.
The closed condensate recovery device of the present invention, has beneficial effect following prominent：Totally enclosed type is run, and is prevented
Pollution of the dissolved gas such as oxygen, carbon dioxide to condensate；Solve the problems, such as that water pump operationally produces cavitation；Avoid
Open-type condensate tank forms caused by secondary flash vapour easily superpressure, the problem of can not running.
Brief description of the drawings
Fig. 1 is the structural representation of the closed condensate recovery device.
Embodiment
As shown in figure 1, the closed condensate recovery device includes a collecting container 1, the top of the collecting container 1
Spiral coil 2 is provided with, middle part is provided with steam-water separation condenser 3, and bottom is provided with water storage device 4.
The water storage device 4 is connected by pipe valve 6 with electric-motor pump, and the bottom of the water storage device 4 is provided with sewage draining exit 43,
Be provided with liquid level sensor in the water storage device 4, the liquid level sensor is provided with two groups up and down, the liquid level sensor with
Electric-motor pump is connected, for providing enabling signal and stop signal.Liquid level sensor 41 above is used to judge whether to open, under
The liquid level sensor 42 in face is used to judge whether to close.
The collecting container is additionally provided with safety valve 52, for the buffering in the case where handling associated steam and can not complete
Function, the safety valve 52 are connected to the relay pipe 5 for being provided with expansion joint, and the other end of the relay pipe 5 is connected to helical disk
Pipe 2.
The relay pipe 5 is provided with shell, and the expansion joint is provided with more piece, and often one group of section correspondence can open upper and lower
Housing, pressure sensor is both provided with inside and outside each expansion joint, the pressure sensor sense on the inside of first segment expansion joint
When should arrive certain numerical value, the upper-lower casing outside first segment expansion joint opens；Pressure sensing in the outside of first segment expansion joint
Device senses that expansion joint has propped up upper-lower casing, and the pressure sensor on the inside of the second section expansion joint senses certain numerical value
When, the second upper-lower casing for saving outside expansion joint opens；Carry out successively, the quantity that can be so opened according to upper-lower casing determines
Whether overload at present.When last upper-lower casing all opens, reply expansion joint is deflated, and reduces pressure.
In the case where pressure value is inadequate, upper-lower casing can close, and block expansion joint.
In use, setting pressure gauge on the collecting container 1, for monitoring collecting container pressure inside the tank, work as collecting container
When high temperature water pressure exceeds safe pressure in tank, the safety valve 52 that collecting container is set is opened, the steam in tank is discharged to setting
There is the relay pipe of expansion joint, the other end of the relay pipe is connected to spiral coil.
Further, the collecting container is connected with water replanishing device.The steam-water separation condenser 3 is multiaperture-type carbonated drink
Separator.
The closed condensate recovery device of the present invention, has beneficial effect following prominent：Totally enclosed type is run, and is prevented
Pollution of the dissolved gas such as oxygen, carbon dioxide to condensate；Solve the problems, such as that water pump operationally produces cavitation；Avoid
Open-type condensate tank forms caused by secondary flash vapour easily superpressure, the problem of can not running.
