Abstract
A steam pocket sewage disposal expander comprises an expander shell, a sewage inlet is formed in the lateral wall of the expander shell, the sewage inlet stretches out of the shell to be connected with a steam pocket blow-off line, a steam exhaust port is formed in the upper end of the expander shell, a water discharge port is formed in the lower end of the expander shell, a steam-water separator is arranged in a cavity of the expander shell, and the steam-water separator is located below the steam exhaust port. The steam pocket sewage disposal expander is further provided with a damping fixing device used for reducing impact to gutter, buffering shock to a water outlet pipeline and reducing equipment noise.
Description
Technical field
The utility model relates to a kind of boiler blow-off equipment, and a kind of drum blowdown expander is particularly applicable to interruption and the continuous blowdown process of nitric acid production oxidation furnace drum.
Background technology
In boiler for producing process, operation along with boiler, be admitted in the feedwater of drum with certain salinity, particularly in pot, carry out after dosing processing, the fouling tendency material of pot water changes grain slag into, in addition,, because pot water is to corrosion of metal, also can produce some erosions, therefore, in boiler water, can contain various solubilities and insoluble impurities, in equipment running process, these impurity only have a seldom part to be taken away by steam, the overwhelming majority is still stayed in water, along with boiler operatiopn, boiler water constantly evaporates, and these impurity concentrations also increase gradually.Boiler water impurity concentration is excessive, has a strong impact on the quality of steam, meanwhile, also can cause the fouling and corrosion of boiler-steam dome, affects the safe operation of boiler.In order to control boiler water quality, must carry out blowdown measure to boiler, the boiler water with salt matter and grain slag pollutant is discharged, and supplement with clear feedwater.
At present, in boiler for producing, drum blowdown major part used is directly by drum, by blow-off line, boiler water to be entered to blowdown irrigation canals and ditches.When carrying out drum blowdown, due in boiler in high pressure conditions, cause boiler water usually with very large pressure, the boiler water of discharging from drum blow-off line can be mingled with a large amount of steam and drop, under pressure draining trench is caused to very large impact, and drop and steam are flown everywhere, and cause the significantly vibrations of blow-off line, produce very large noise, have a strong impact on work on the spot environment, equipment and blowdown irrigation canals and ditches are produced to damage to a certain degree.
Summary of the invention
The purpose of this utility model is to provide a kind of drum blowdown expander, is provided with damping fixing device, for reducing the impact to draining trench, slows down the concussion to outlet conduit, reduces equipment noise.
The utility model is that to solve this technical problem adopted technical scheme as follows:
A kind of drum blowdown expander, comprise expander housing, in described expander housing sidewall, be provided with sewer import, described sewer import is stretched out described expander hull outside and is connected with drum blow-off line, upper end at described expander housing is provided with steam drain, lower end at described expander housing is provided with discharge outlet, in described expander housing chamber, be provided with steam-water separator, described steam-water separator is positioned at described steam drain below, described drum blowdown expander is also provided with damping fixing device, described damping fixing device comprises bracing frame, supporting leg and earth plate, support frame as described above is fixedly connected between discharge outlet and expander housing, for reducing the concussion of outlet conduit, described supporting leg is connected with expander housing bottom, by support, be fixed on the ground, described earth plate is arranged on described supporting leg, be used for fixedly drum blowdown blowdown expander, the problems such as noise that slow down equipment concussion and produce.
As a kind of preferred embodiment, described steam-water separator is wire mesh demister.
As a kind of preferred embodiment, the quantity of described expander lower housing portion supporting leg is four, for firm support housing.
As a kind of preferred embodiment, described expander lower housing portion is also provided with draining and regulates mouth.
As a kind of preferred embodiment, described expander housing middle part is also provided with the manhole passing through for maintenance personal.
The beneficial effects of the utility model are: this drum blowdown expander is separated into steam and spent hot water by the sewer adiabatic expansion from boiler, and steam is drawn by steam drain, also can introduce the reuse of low-pressure steam pipe network, and spent hot water drains automatically by discharge outlet.Use after drum blowdown expander, can effectively reduce the impact that draining trench is caused, avoid drop and steam to fly everywhere, reduce the vibrations of blow-off line, the equipment noise of making reduces, there is obvious sound deadening, improve work on the spot environment, and the damage of equipment and blowdown irrigation canals and ditches is all obviously alleviated.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model drum blowdown expander.
1-supporting leg, 2-discharge outlet, 3-expander housing, the import of 4-sewer, 5-gusset, 6-gripper shoe, 7-steam drain, 8-steam-water separator, 9-manhole, 10-earth plate.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1, the drum blowdown expander the utility model proposes comprises expander housing 3, on described expander housing 3 sidewalls, be provided with sewer import 4, described sewer import 4 is stretched out described expander housing 3 outsides and is connected with drum blow-off line, in the upper end of described expander housing 3, be provided with steam drain 7, in the lower end of described expander housing 3, be provided with discharge outlet 2, in described expander housing 3 chambeies, be provided with steam-water separator (preferably wire mesh demister) 8, described wire mesh demister 8 is positioned at described steam drain 7 belows, described drum blowdown expander is also provided with by bracing frame, the damping fixing device that four supporting legs 1 and earth plate 10 form, support frame as described above is fixedly connected on 3 of discharge outlet 2 and expander housings, described supporting leg 1 is connected with expander housing 3 bottoms, by support, be fixed on the ground, described earth plate 10 is arranged on described supporting leg 1.In addition, in described expander housing 3 bottoms, be provided with draining and regulate mouth and manhole 9.
Boiler blowdown water enters drum blowdown expander, sewer is expansion decompression in cylinder, and part is vaporized into indirect steam, and steam carries out after carbonated drink separation through the steam-water separator of expander enclosure interior, the sewer staying regulates a mouthful discharge by discharge outlet or draining.
This drum blowdown expander is separated into steam and spent hot water by the sewer adiabatic expansion from boiler, and steam is drawn by steam drain, also can enter the reuse of low-pressure steam pipe network, and spent hot water drains by discharge outlet.
