Abstract
The utility model discloses a fume condenser which belongs to an energy-saving device for a boiler. The fume condenser comprises fin tubes, a fume inlet and a fume outlet, wherein each fin tube is a steel-aluminum composite fin tube. The utility model is characterized in that the steel-aluminum composite fin tube has large fume contact area, high heat transmission efficiency and complete condensation of fume; because of the adoption of tube plate welding, all fin tube bundles are centralized between two tube plates, thereby having compact structure and simple production; the inside (in contact with fume) of the tube plate is provided with a dense enamel coating, and the enamel coating shaped at a high temperature has the same expansion coefficient as the matrix metal and hardly sheds, thereby solving the problem of steel plate corrosion.
Description
Technical field
The utility model belongs to energy-saving device of boiler, is specifically related to a kind of condensing unit that absorbs boiler tail flue gas.
Background technology
Flue gas condenser be a kind of to Industrial Boiler row to the treatment facility that the high-temperature flue gas of atmosphere carries out condensation and purification, be widely used in industry-by-industries such as food, application, environmental protection.Flue gas condenser mainly is to utilize heat conduction and heat convection principle to reduce the temperature of the high-temperature flue gas of Industrial Boiler discharging, thereby reduce emission of harmful substances such as sulfide and nitride, simultaneously the cold fluid after the heating is used for other purposes, to realize energy-conserving and environment-protective largely.There are a lot of shortcomings in existing flue gas condenser, such as: 1. traditional condenser is accompanied by decrease of temperature in heat transfer process, the SO in the combustion product
x, NO
xThe H that forms

3And HNO
3Make steel plate produce corrosion, so the service life of equipment is short, maintenance cost is high; 2. the condenser fin pipe adopts the carbon steel spiral fin coil, and heat transfer property is bad; 3. adopt bend pipe to connect between the finned tube, interfix plate location makes loaded down with trivial details; 4. the condenser weld seam is more, distortion is big, the overall appearance weak effect.
The utility model content
The technical problems to be solved in the utility model be the flue gas condenser life-span short, heat transfer property is bad, making is loaded down with trivial details, not attractive in appearance, a kind of flue gas condenser is provided, its long service life, good heat-transfer, manufacture craft is simple, overall appearance is effective.
The technical solution of the utility model realizes with following method:
Flue gas condenser comprises finned tube, gas approach and exhanst gas outlet, and described finned tube is a steel-aluminum composite fin tube.
Described finned tube two ends and tube sheet welding.
Described tube sheet inboard is covered with enamel coating.
The flue gas contact area of steel-aluminum composite fin tube of the present utility model is big, and the heat exchange efficiency height makes flue gas condensing thorough; The welding of employing tube sheet, all finned-tube bundles concentrate between two tube sheets, and compact conformation, preparation are simply, tube sheet inboard (contacting a side with flue gas) has fine and close enamel coating, enamel coating through high-temperature shaping is consistent with the parent metal coefficient of expansion, and difficult drop-off has solved the steel plate corrosion problem.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, flue gas condenser of the present utility model comprises circulating water intake 4, circulating water outlet 1, finned tube 2, gas approach 5 and exhanst gas outlet 6, and described finned tube 2 is steel-aluminum composite fin tubes.
Described finned tube 2 two ends and tube sheet 3 welding.
Described tube sheet 3 inboards are covered with enamel coating.
Finned tube 2 and tube sheet 3 welding, can realize all tube head argon shields automatically weldering finish, guarantee welding quality, do not destroy enamel coating, the adhering to closely of fine and close enamel coating, difficult drop-off can prevent steel plate corrosion.
The utility model is connected with control system, has manual function, control parameter demonstration and fault and alarm indication.Automatic control system is safe and reliable, and is easy to operate, through accurate measurement and the control to boiler smoke temperature, acid dew point, resistance and heat exchange amount, the safe and reliable fume afterheat of recovery more than 120 ℃.Structure relates to rationally, heat exchange efficiency is high, flue gas resistance is little.
