Abstract
The utility model relates to a low-temperature flue gas heater, which comprises two vertical supporting orifice plates. The two sides of the supporting orifice plate are respectively provided with a vertical side plate which is connected with the corresponding supporting orifice plate and covers a square expansion joint outside the supporting orifice plate; the two ends of a heat exchange tube bundle are arranged in the through hole of the corresponding supporting orifice plate and connected with the corresponding supporting orifice plate in a sealing way; the two vertical sides of the two side plates are respectively connected with an air inlet pipe and an air outlet pipe; and the two horizontal sides thereof are respectively connected with a flue gas inlet pipe and a flue gas outlet pipe. The utility model is characterized in that the outer surfaces of the heat exchange tubes are plated with an enamel layer. The utility model has the advantages of simple structure, security, reliability and high thermal efficiency. The enamel material is easily available, thereby reducing the use of the low-temperature corrosion material, and reducing the equipment cost. Because the outer surfaces of the heat exchange tubes are plated with the enamel layer and are very smooth, the soot deposit thereon can be easily cleaned by the soot deposit blowing equipment. The service life of the utility model is long. The utility model can reduce the temperature of the flue gas, save the energy and protect the environment.
Description
Technical field:
The novel a kind of heat exchanger, particularly tubular heat exchanger of relating to of this reality.
Background technology:
At present, in the reheating furnace energy-saving equipment in fields such as oil, chemical industry and metallurgy, the low-temperature flue gas heat collector is to use one of more equipment.This low-temperature flue gas heat collector mainly includes side plate, gripper shoe, heat exchanger tube tube bank, square expansion joint, smoke entrance pipe and air ports pipe.Owing to generally all contain sulfur oxide and moisture in the flue gas medium, they can react and generate acid.When heat pipe metallic walls temperature was lower than flue gas acid dew point, flue gas will cause the corrosion of the sulfide opposite heat tube in the flue gas at the heat pipe surface sweating.In order to improve the resistance to corrosion of heat pipe, someone designs and adopts low temperature resistant corrosion material ND steel heat exchanger tube, but since the smelting process of domestic ND steel that is that all right is ripe, particularly the Cu Composition Control in the ND steel is bad, corrosion can only be delayed, cold end corrosion can not be prevented completely; Also the someone designs and improves heat exchanger tube tube bank surface wall temperature, promptly improves exhaust gas temperature, and its weak point is to have reduced heat energy recovery rate, and environmental pollution is increased.
Summary of the invention:
The purpose of this utility model is to provide a kind of material to be easy to get, cost is low, the not only low-temperature flue gas heat collector of energy-conservation but also environmental protection.The utility model is the enamel layer that is coated with anti-cold end corrosion on existing heat exchanger tube surface.Preferably heat exchanger tube is a turbolator pipe of establishing spoiler in the pipe.Heat exchanger tube adopts light pipe.
When flue gas enters from flue gas inlet tube, through smoke-box, by turbolator tube bank heat exchange heat transferred is restrained interior air, temperature reduces the back and discharges from smoke outlet tube, air enters from the air intlet pipe, by the turbolator tube bank, absorb the flue gas liberated heat, temperature flows out from the air outlet slit pipe after raising.The utility model compared with prior art has following advantage:
1, simple in structure, safe and reliable, the thermal efficiency is high.
2, enamel material is easy to get, and has reduced the consumption of cold end corrosion material, has reduced equipment cost.
3, because heat exchange pipe external surface has plated enamel, very smooth, the dust stratification on it is very easily removed with the dust stratification slag-blowing equipmemt, long service life.
4, can reduce exhaust gas temperature, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is that schematic diagram cuts open in the utility model master office of looking.
Fig. 2 is the local cross-sectional schematic of amplifying of the utility model heat exchanger tube.
The specific embodiment:
In the schematic diagram of low-temperature flue gas heat collector shown in Figure 1, on the framework 1 that shaped steel constitutes, be provided with two vertical gripper shoes 2, two ends are fixed with a limit of square expansion joint 3 respectively about the back side of one of them gripper shoe, and another limit of this square expansion joint fixedly is on its corresponding shaped steel.Above-mentioned two gripper shoes are orifice plate, and the outside is coated with the turbolator pipe 5 of enamel layer 4, and as shown in Figure 2, its two ends place respectively in the through hole of these two gripper shoe correspondences, and are tightly connected.Be provided with the vertical side plate 6 that links to each other with them and its square expansion joint in outside is covered in above-mentioned two gripper shoe both sides, itself and two gripper shoes formation square tube shape smoke-box.Two vertical edges of above-mentioned biside plate advance 7 with air respectively, outlet 8 links to each other, and two horizontal sides of above-mentioned biside plate advance 9 with flue gas respectively, outlet 10 links to each other.
