Abstract
The invention discloses a copious cooling type smoke deaerator. The invention adopts the technical scheme that the copious cooling type smoke deaerator comprises a water reservoir, a water inlet pipe and a water outlet pipe; the water reservoir is divided by a clapboard; and a smoke exhaust pipeline runs through the water reservoir along a direction vertical to the clapboard. According to the copious cooling type smoke deaerator provided by the invention, the smoke flows from a smoke inlet to a smoke outlet of the smoke exhaust pipeline, and the temperature of the smoke gradually reduces. The deaerator consumes no steam and heats the soft water entering a boiler by using the waste heat of the tail gas and the latent heat of the phase change of the steam in the boiler; the soft water enters the boiler from the water inlet pipe where the temperature of the smoke is low, is gradually heated up and then goes out from the side where the temperature of the smoke is high; the outlet water temperature can reach 100 DEG C and the oxygen removal rate can reach 99%; and the deaerator can effectively prevent the boiler from oxygen corrosion, thereby prolonging the service life of the boiler. Meanwhile, the deaerator can reduce the temperature of the exhaust smoke of the boiler to be 70-80 DEG C, thereby improving the efficiency of the boiler by about 10% and reducing the fuel coal consumption by about 12%.
Description
Technical field
The present invention relates to a kind of boiler feed, be specifically related to a kind of flue gas deep cooling type oxygen-eliminating device.
Background technology
Dissolved oxygen can cause the corrosion of boiler and relevant device in the boiler feedwater, 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 the 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.
Summary of the invention
It is better that the technical problem that the present invention solves has provided 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 the boiler feedwater.
Technical scheme of the present invention 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 the water container.Water inlet pipe of the present invention 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 of the present invention 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 invention, 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, in the service life of prolonged boiler, this oxygen-eliminating device can be down to 70-80 ℃ with the exhaust gas temperature of boiler simultaneously, improve boiler efficiency about 10%, reduce coal-fired consumption about 12%.This Deaerator Structure advantages of simple, operating cost is lower, has preferably popularizing value.
