Abstract
The utility model discloses a flue gas deep-cold type deaerator which comprises a water holding reservoir, a water inlet pipe and a water outlet pipe, wherein the water holding reservoir is separated by separating plates, and gas exhausting pipelines penetrate through the water holding reservoir along the direction perpendicular to the separating plates. According to the flue gas deep-cold type deaerator, flue gas flows from a gas inlet of the gas exhausting pipeline to a gas outlet, the temperature of the flue gas is gradually reduced, the deaerator does not consume steam, soft water which is injected to a boiler can be heated by means of waste heat of tail gas of the boiler and latent heat of phase change of water steam, the soft water enters from a flue gas low-temperature side water inlet pipe, the temperature gradually rises, the soft water is discharging when reaches to the flue-gas high-temperature side, the temperature of water discharging can reach 100 DEG C, the deoxigenation rate reaches over 99%, and therefore the boiler can be effectively prevented from oxygen corrosion and the service life of the boiler is prolonged. Meanwhile, the flue gas deep-cold type deaerator can reduce the gas exhausting temperature of the boiler to 70-80 DEG C, the efficiency of the boiler can be improved by about 10%, and consumption of fire coal can be reduced by about 12%.
Description
Technical field
The utility model relates to a kind of boiler feed, is specifically related to a kind of flue gas deep cooling type oxygen-eliminating device.
Background technology
In boiler feedwater, dissolved oxygen can cause the corrosion of boiler and relevant device, in order to prevent the generation of this phenomenon, usually the oxygen-eliminating device that adopts is the body sealing, vacuumize or heat the water that makes in oxygen-eliminating device and reach boiling point, dissolved oxygen just can be overflowed from water, thereby reaches the purpose of boiler supply water deaerating, and the design comparison of above-mentioned boiler feed is complicated, operating cost is also higher, applies being subject to certain restrictions.
The utility model content
It is better that the technical problem that the utility model solves has been to provide a kind of deaerating effect, the flue gas deep cooling type oxygen-eliminating device that operating cost is cheap, this oxygen-eliminating device does not consume steam, utilizes the waste heat of boiler exhaust gas flue gas and the latent heat of phase change of water vapour that soft water is heated, and removes the dissolved oxygen in boiler feedwater.
The technical solution of the utility model is: a kind of flue gas deep cooling type oxygen-eliminating device, comprise water container, water inlet pipe and outlet pipe is characterized in that: described water container is separated by dividing plate, smoke discharging pipe along perpendicular to the dividing plate direction through between water container.Water inlet pipe described in the utility model is located at the bottom of the water container sidewall of smoke discharging pipe outlet flue one side, and described outlet pipe is located at the top that smoke discharging pipe advances the water container sidewall of mouth one side.Smoke discharging pipe described in the utility model becomes different number and diameters according to the different designs of boiler exhaust gas amount and water container shape.
flue gas deep cooling type oxygen-eliminating device of the present utility model, flue gas flows to outlet flue by the mouth that advances of smoke discharging pipe, the temperature of flue gas reduces from high to low gradually, this oxygen-eliminating device does not consume steam, the latent heat of phase change that utilizes the waste heat of boiler exhaust gas and water vapour heats the soft water of boiler water inlet pipe, soft water enters from the low temperature side water inlet pipe, heat up gradually, to the high temperature side water outlet, the outlet water temperature can reach 100 ℃, the deoxygenation rate reaches more than 99%, can effectively prevent boiler oxygen corrosion, the service life of prolonged boiler, this oxygen-eliminating device can be down to 70-80 ℃ with the exhaust gas temperature of boiler simultaneously, raising boiler efficiency 10% left and right, reduce coal-fired 12% left and right that consumes.This Deaerator Structure advantages of simple, operating cost is lower, has popularizing value preferably.
Description of drawings
Fig. 1 is structural representation of the present utility model; Fig. 2 is the right view of Fig. 1.
Drawing explanation: 1, water container, 2, dividing plate, 3, smoke discharging pipe, 4, water inlet pipe, 5, outlet pipe, 6, advance mouth, 7, outlet flue.
The specific embodiment
Describe by reference to the accompanying drawings embodiment in detail.A kind of flue gas deep cooling type oxygen-eliminating device comprises water container 1, water inlet pipe 4 and outlet pipe 5, described water container 1 is separated by dividing plate 2, smoke discharging pipe 3 along perpendicular to dividing plate 2 directions through between water container 1.Described water inlet pipe 4 is located at the bottom of water container 1 sidewall of smoke discharging pipe 3 outlet flue 7 one sides, and described outlet pipe 5 is located at the top that smoke discharging pipe 3 advances water container 1 sidewall of mouth 6 one sides.Described smoke discharging pipe 3 becomes different number and diameters according to the exhaust smoke level of boiler and the different designs of water container shape.
flue gas deep cooling type oxygen-eliminating device of the present utility model, flue gas flows to outlet flue by the mouth that advances of smoke discharging pipe, the temperature of flue gas reduces gradually, this oxygen-eliminating device does not consume steam, the latent heat of phase change that utilizes the waste heat of boiler exhaust gas and water vapour heats the soft water of boiler water inlet pipe, soft water enters from the low temperature side water inlet pipe, heat up gradually, to the high temperature side water outlet, the outlet water temperature can reach 100 ℃, the deoxygenation rate reaches more than 99%, can effectively prevent boiler oxygen corrosion, the service life of prolonged boiler, this oxygen-eliminating device can be down to 70-80 ℃ with the smoke evacuation flue-gas temperature of boiler simultaneously, raising boiler efficiency 10% left and right, reduce coal-fired 12% left and right that consumes.This Deaerator Structure advantages of simple, operating cost is lower, has popularizing value preferably.
