Abstract
The utility model relates to a heat exchanger used on soot blower of power plant, which can make ash and slag being difficult to bind. The utility model mainly consists of a tube bundle conjunction and a shell conjunction fitted tighter with the tube bundle conjunction. The tube bundle conjunction is arranged inside the shell conjunction. The utility model is characterized in that the tube bundle conjunction consists of a heat exchange tube, an end plate, baffles and a supporting tube. The heat exchange tube is arranged on the end plate supported with the baffles. The space between the baffles is separated by the supporting tube. The utility model has the advantages that: the structure is compact and rational; the utility model can save cost and energy with steam heating; because the heat exchange tube is made of aerial high-performance radiating tube which is got by coating high-performance aluminum spiral tube outside seamless steel tube, the heat exchange tube can resist wear, improve ribbed coefficient of low rib spiral tube, increase heat exchange area and improve heat exchange efficiency; the heat exchange tube is an U-shaped tube, which has good thermal expansion self-compensation capacity. The heat exchange tube not only has heat exchange capability, but also has a gas storage capability.
Description
Technical field:
The utility model relates to a kind of heat exchanger, is used for the power plant soot blower, makes the lime-ash prevented from caking, belongs to technical field of heat exchange devices.
Background technology:
Before the utility model was made, in the prior art, heat exchanger mainly adopted electric energy to heat.Mainly form by bobbin carriage conjunction, end plate, stay pipe, deflection plate, tube bank conjunction and cylindrical shell conjunction etc.Bobbin carriage conjunction and cylindrical shell conjunction are fastening, in the tube bank conjunction radiating tube, stay pipe and end plate etc. are installed, and the tube bank conjunction is installed in the cylindrical shell conjunction, and are furnished with parts such as safety valve and turnover steam port.The heat converter structure complexity of this kind structure, owing to adopt electrical heating, manufacturing cost height, and also heat exchange efficiency is low, and dedusting effect is poor.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of compact conformation, reasonable is provided; Can increase heat exchange area, improve heat exchange efficiency; Adopt Steam Heating, can reduce cost greatly, and can improve the heat exchanger of dedusting effect.
Main solution of the present utility model is achieved in that
The utility model mainly adopts bobbin carriage conjunction 1 and 10 fastening connections of cylindrical shell conjunction, tube bank conjunction 7 is installed in the cylindrical shell conjunction 10, it is characterized in that restraining in the conjunction 7 and form by heat exchanger tube 6, end plate 3, deflection plate 5, stay pipe 4, heat exchanger tube 6 is scurried on end plate 3, deflection plate 5 supports heat exchanger tube 6, adopts stay pipe 4 to separate between deflection plate 5.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, rationally; Adopt Steam Heating, low cost of manufacture, energy energy savings; Because heat exchanger tube adopts aviation high efficiency and heat radiation pipe, at the efficient aluminum helix tube of seamless steel pipe external application, it has abrasive resistance, and the inned coefficient of low rib helix tube is improved, and increases heat exchange area, improves heat exchange efficiency; Because heat exchanger tube is shaped as " U " shape pipe, it has good thermal expansion and compensates voluntarily, the heat exchange effect is not only arranged, and can play the gas storage effect.
Description of drawings:
Fig. 1 is the utility model structural front view:
The specific embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of bobbin carriage conjunction 1, end plate 3, stay pipe 4, deflection plate 5, heat exchanger tube 6, tube bank conjunction 7, safety valve 8, baffle plate 9 and cylindrical shell conjunction 10 etc.On cylindrical shell conjunction 10 left sides is bobbin carriage conjunction 1, and adopts bolted to connect, and is provided with turnover steam port 2 on bobbin carriage conjunction 1.On cylindrical shell conjunction 10, be provided with turnover air scoop 11,, be provided with safety valve 8 at cylindrical shell conjunction 10 tops in order to guarantee the safety of heat exchange.For the air after preventing to heat is directly gone out from air outlet slit, in cylindrical shell, place a baffle plate 9, and bearing 12 is housed in the bottom of cylindrical shell from air outlet slit a distance, play support and installation effect.Tube bank conjunction 7 mainly is made up of tens heat exchanger tubes 6, end plate 3, polylith deflection plate 5, many stay pipes 4.Heat exchanger tube 6 is scurried on end plate 3, and polylith deflection plate 5 plays the effect of supporting heat exchanger tube, adopts stay pipe 4 to separate between the deflection plate 5.Heat exchanger tube 6 connects with end plate 3 usefulness welding ribbed pipe.Heat exchanger tube 6 is shaped as the U-shaped pipe, can make heat exchanger that good sealing property is arranged.
The operation principle of the present utility model and the course of work:
1. the operation principle of heat exchanger: cold air and high-temperature steam heat exchanger tube in outer by heat exchanger tube carry out sufficient heat exchange, thereby have improved the temperature of air, reach the air themperature of use.
2. the course of work of heat exchanger: cold air enters in the cylindrical shell from the import and export on the heat exchanger cylindrical shell, and is moving through deflection plate march linear flow, flows out from the gas outlet of heat exchanger again.Steam flows into from the import on heat exchanger top, flow by " U " shape in the heat exchanger tube, get back in the bobbin carriage and flow out, the higher sufficient heat exchange of steam of temperature in cold air and the heat exchanger tube from steam (vapor) outlet, the air themperature that flows out from the gas outlet improves greatly, reaches desirable air themperature.
Claims (2)
1. heat exchanger, it is characterized in that adopting bobbin carriage conjunction (1) and fastening connection of cylindrical shell conjunction (10), tube bank conjunction (7) is installed in the cylindrical shell conjunction (10), it is characterized in that restraining in the conjunction (7) and form by heat exchanger tube (6), end plate (3), deflection plate (5), stay pipe (4), heat exchanger tube (6) is scurried on end plate (3), deflection plate (5) supports heat exchanger tube (6), adopts stay pipe (4) to separate between deflection plate (5).
