Description
Technical field
The utility model belongs to boiler anti-corrosion equipment technical field, and in particular to a kind of Industrial Boiler with hold pressure nitrogen charging anti-corrosion
Device.
Background technology
Industrial Boiler is commonly used as the steam that generates electricity and produce in departments such as electric power, chemical industry, light industrys, it is ensured that the peace of Industrial Boiler
Entirely, economical operation, to developing national economy, ensure that the living needs of the people has critically important meaning.To industrial boiler operation
Requirement be：Safe steam supply of guaranteeing both quality and quantity is first had to, secondly also requires boiler plant economical running under secure conditions.
It is many to influence the factor of Industrial Boiler safety and economic operation, is on the one hand due to that boiler design, manufacture, installation, maintenance improper are drawn
Rise.One boiler, if design is bad, manufacture installation quality is not again good enough, can not reach safety and economic operation certainly.The opposing party
Face is not carried out then entirely due to caused the reason in operation, such as when starting by operational procedure, usually boiler technology pipe
Science and engineering is made poor, especially does not pay attention to maintaining after blowing out, and the water in some boilers does not discharge clean.It is extraneous after boiler disables
Air largely will enter in boiler water system, though now boiler has discharged water, one layer is always adhered on Boiler Metallic surface
Moisture film, the oxygen in air are just dissolved in this moisture film, it is easy to cause the corrosion of dissolved oxygen, it corrodes the speed of boiler than pot
Stove is faster during running.If have the salt crust that can be dissolved in moisture film on Boiler Metallic surface, corrosivity is stronger.Practice card
Bright, the boiler for producing heavy corrosion is formed during being mostly blowing out, and in operation caused by development.Therefore, in shutdown period
Between use appropriate guard method, to preventing boiler corrosion, it is ensured that safe operation, the service life of prolonged boiler, have important
Meaning.
Utility model content
The purpose of this utility model is that providing one kind utilizes original boiler pipe network, by original boiler pipe network
It is filled with the method for nitrogen and then the anti-corrosive apparatus of protection left and right is played to boiler.
To achieve the above object, the utility model provides following technical scheme：
A kind of Industrial Boiler is with holding pressure nitrogen charging anti-corrosive apparatus, including boiler body, nitrogen main pipe, isolating valve, arranges main valve surely
With economizer influent header Draw off valve, isolating valve and surely row main valve be sequentially arranged on the pipeline being connected with boiler body, position
In isolating valve and surely arrange and nitrogen main pipe is connected with the pipeline between main valve, the nitrogen in nitrogen main pipe passes through after entering boiler body
It is outdoor to cross the discharge of economizer influent header Draw off valve.
Preferably, boiler body includes the lower collecting box that be connected with determining row's total valve pipeline, lower collecting box respectively by down-comer with
Water screen tube is connected with drum, upper header is additionally provided with water screen tube, drum is successively with evaporating screen, outlet header, economizer, province
Coal device influent header connects with economizer influent header Draw off valve, and economizer influent header also connects with feedwater piping total valve
Connect.
Compared with prior art, the beneficial effects of the utility model are：
The utility model effectively make use of nitrogen pipeline in production company area, it is not necessary to increase extra input, i.e.,
Original boiler pipe network can be connected with the nitrogen pipeline in region, small investment, reduce production cost, and use nitrogen charging
Preserving method is protected to boiler, and the protection period length of nitrogen charging anti-corrosion protection boiler, positive effect, operating procedure is simple,
Labor intensity of operating staff is small.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1. main valve, 4. lower collecting box, 5. down-comers, 6. drums, 7. evaporations are arranged in nitrogen main pipe, 2. isolating valves, 3. surely
Screen, 8. outlet headers, 9. economizer influent headers, 10. feedwater piping total valves, 11. economizers, 12. water screen tubes, on 13.
Header, 14. economizer influent header Draw off valve.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of Industrial Boiler with hold pressure nitrogen charging anti-corrosive apparatus, including boiler body, nitrogen main pipe 1, isolation
Valve 2, main valve 3 and economizer influent header Draw off valve 14 are arranged surely, isolating valve 2 and surely row's main valve 3 are sequentially arranged at and boiler body
On the pipeline being connected, arrange positioned at isolating valve 2 and surely and nitrogen main pipe 1 is connected with the pipeline between main valve 3, in nitrogen main pipe 1
Nitrogen enter after boiler body and discharge outdoor by economizer influent header Draw off valve 14, boiler body includes and to determine row total
The lower collecting box 4 of the pipeline of valve 3 connection, lower collecting box 4 are connected by down-comer 5 and water screen tube 12 with drum 6 respectively, water screen tube 12
On be additionally provided with upper header 13, drum 6 is successively with evaporation screen 7, outlet header 8, economizer 11, economizer influent header 9 and saving coal
Device influent header Draw off valve 14 is connected, and economizer influent header 9 is also connected with feedwater piping total valve 10.
Boiler water must be put only, close isolating valve 2, feedwater piping total valve 10 when specifically used by the utility model,
Economizer influent header Draw off valve 14 is opened, opens and arranges main valve 3 surely, opens nitrogen main pipe 1；Nitrogen is logical by arranging main valve 3 surely
To cross lower collecting box 4, down-comer 5, water screen tube 12 and upper header 13 and enter drum 6, nitrogen enters evaporation screen 7 after drum 6 collects,
Entered again by pipeline with this in economizer exit header 8, economizer 11 and economizer influent header 9, now use portable oxygen
Oxygen content at the mouth of pipe of content instrument measurement economizer influent header Draw off valve 14, when oxygen content is less than 19.5% after testing, visually
Qualified for nitrogen charging anti-corrosions such as boiler tubing, each headers, nitrogen can directly be discharged by economizer influent header Draw off valve 14.
