Description
Technical field
The utility model relates to a kind of flue gas condensing heat exchanger, for flue gas desulfurization and the UTILIZATION OF VESIDUAL HEAT IN of coal-burning boiler.
Background technology
Boiler exhaust gas loss is one maximum in its every loss, therefore low-grade flue gas waste heat is reclaimed, be one of important channel of boiler energy-saving potentiality, and fume afterheat resource is the resource that coal-burning boiler power plant is difficult to make full use of always, reason is mainly cold end corrosion problem.Coal-burning boiler smoke evacuation dew point is about 55 DEG C, and general cryogenic heat exchanger need run at higher than this temperature, and waste heat recovery effect is bad.The utility model heat exchanger can run under far below smoke evacuation dew-point temperature, exhaust gas temperature is down to less than 40 DEG C, can realizes flue gas condensing desulfurization while degree of depth Mist heat recovering.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of heat exchanger for flue gas condensing desulfurization, and structure is simple, effectively can realize the effect of flue gas desulfurization while recycling fume afterheat.
Technical scheme: for achieving the above object, the technical solution adopted in the utility model is:
A kind of heat exchanger for flue gas condensing desulfurization, comprise heat exchanger tube, housing, cooling water inlet, coolant outlet, cooling water inlet header and coolant outlet header, on the upside of described housing, outer wall is axially provided with cooling water inlet header along housing, described cooling water inlet header is provided with cooling water inlet, on the downside of described housing, outer wall axially arranges coolant outlet header along housing, described coolant outlet header is provided with coolant outlet, described enclosure interior is provided with some heat exchanger tubes, described heat exchanger tube one end is communicated with cooling water inlet header, the described heat exchanger tube other end is communicated with coolant outlet header, on the downside of described housing, outer wall offers condensate outlet.
Further, external condensed fluid collection tank on described condensate outlet.
Further, between described heat exchanger tube, stagger arrangement parallel with one another is arranged, and the flue gas in the axis of described heat exchanger tube and housing moves towards perpendicular.
Further, described heat exchanger tube is carborundum engineering ceramics, and structure adopts light pipe form.
Beneficial effect: heat exchanger structure of the present utility model is simple, and novel silicon carbide engineering ceramics heat exchanger tube has very high thermal conductivity and resistance to corrosion, can realize the object of flue gas condensing desulfurization while deep exploitation fume afterheat.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Be illustrated in figure 1 a kind of heat exchanger for flue gas condensing desulfurization, comprise heat exchanger tube 1, housing 2, cooling water inlet 3, coolant outlet 4, cooling water inlet header 6 and coolant outlet header 7.On the upside of described housing 2, outer wall is axially provided with cooling water inlet header 6 along housing 2, described cooling water inlet header 6 is provided with cooling water inlet 3; On the downside of described housing 2, outer wall axially arranges coolant outlet header 7 along housing 2, described coolant outlet header 7 is provided with coolant outlet 4.Described housing 2 inside is provided with some heat exchanger tubes 1, and described heat exchanger tube 1 is carborundum engineering ceramics, and structure adopts light pipe form, and described heat exchanger tube 1 one end is communicated with cooling water inlet header 6, and described heat exchanger tube 2 other end is communicated with coolant outlet header 7.Between described heat exchanger tube 1, stagger arrangement parallel with one another is arranged, and the flue gas in the axis of described heat exchanger tube 1 and housing 2 moves towards perpendicular.On the downside of described housing 2, outer wall offers condensate outlet, external condensed fluid collection tank 5 on described condensate outlet.
Cooling water enters cooling water inlet header 6 from cooling water inlet 3, cooling water pass into some be parallel to each other heat exchanger tube 1 in, flue gas enters in housing 2 perpendicular to heat exchanger tube 1, realizes heat exchange, cooling water after heat exchange passes into coolant outlet header 7, flows out through coolant outlet 4.Period, converge to condensate outlet, and reclaimed by condensed fluid collection tank 5 at the liquefaction water of housing 2 internal condensation, condensed fluid collection tank 5 tank inner condensat liquid needs periodic cleaning.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
