When high-temperature heat-exchanging is worked, high-temperature flue gas in the incinerator enters high-temperature heat-exchanging from the high-temperature flue gas entry of tube side imported equipments and parts 2, flow through successively tube side imported equipments and parts 2, tube side passage, tube side spout member 8 are discharged from the flue gas discharge opening of tube side spout member 8; Extraneous fresh air is entered by the opening of air blast through the shell side imported equipments and parts 9 of low-temperature space heat exchanger 5, and the spray booth (not shown) of discharging the system that enters from the opening of the shell side spout member 11 of high temperature section 41 behind the shell side passage of flowing through is used for spraying and solidifies needs.Fresh air and high-temperature flue gas are respectively after low-temperature space heat exchanger 5,4 heat exchange of high-temperature region heat exchanger in said process, (in fact fresh air and high-temperature flue gas are that tube wall by heat exchanger tube carries out heat exchange), the fresh air temperature rises to about 650 ℃, to meet the requirement of spraying coating process, high-temperature flue gas is from about 800 ℃ about 200 ℃ of dropping to the flue gas discharge opening place of high-temperature flue gas entry, to reach the purpose that reclaims heat energy.
In the process of high-temperature heat-exchanging work, the heat exchanger tube 13 of high temperature section 41 bears very high temperature, therefore bigger swell increment may appear, because the mode with the piston slip between the housing of the front tube sheet 12 of high temperature section 41 and high temperature section 41 is connected, thereby can make both along the relative slippage of fore-and-aft direction, realize cold and hot stress absorption the front tube sheet 12 of high temperature section 41.The heat exchanger tube 13 of high temperature section 41 be arranged in the pore of front tube sheet 12 and not with front tube sheet 12 welding, can relative slippage thereby make between heat exchanger tube 13 and the front tube sheet, realize exchanging the absorption of heat pipe 13 thermal expansions.In addition,, thereby can make both, realize the absorption of heat exchanging device body 1 and the expansion of tube side imported equipments and parts 2 overall thermal along the relative slippage of fore-and-aft direction because the mode of sliding with piston between the housing of high temperature section 41 and the tube side imported equipments and parts 2 is connected.And because high-temperature region heat exchanger 4 has comprised high temperature section 41, the middle-temperature section 42 that links to each other with expansion joint by intermediate connector 6, thereby make the absorption of thermal expansion more reasonable.The more important thing is filling with insulation material 127 between the pipe of the heat exchanger tube before the front tube sheet 12 of high temperature section 41, thereby insulated wall is set one before front tube sheet 12, avoid front tube sheet 12 toasted by high-temperature flue gas, improve the working environment of front tube sheet 12, improve service life, make high-temperature heat-exchanging that the job stability and the reliability of longer-term be arranged.
What more than introduce is preferred implementation of the present invention, and the present invention also can adopt other embodiments, such as:
Between the back tube sheet of high temperature section 41 and the housing be connected or the tube sheet of middle-temperature section 42 connects with the mode that also can adopt piston to slide that is connected between the housing.
The front tube sheet 12 of high temperature section 41 and heat exchanger tube 13 also can adopt welding or expanded joint etc. to fixedly connected mode.
Also can not weld between the back tube sheet of high temperature section 41 and the heat exchanger tube 13 or between the tube sheet of middle-temperature section 42 and the heat exchanger tube and adopt and heat exchanger tube between the mode of filling with insulation material, thereby it is cleaned and changed that heat exchanger tube can be extracted out.
The mode of also sliding with piston between back tube sheet and the housing is connected, thereby the forward and backward tube sheet of high temperature section can be extracted out from housing with heat exchanger tube 13, is convenient to clean and maintenance.
The place ahead of described heat-barrier material also can not baffled 125.
Tube side imported equipments and parts 2 can not have casing 20 yet and directly connect circle 23 in the front end connection side of heat exchanger body 1, and the openend that the side connects circle 23 is provided with the flange 24 that is connected with the high-temperature flue gas outlet of the incinerator (not shown) of system.
Heat exchanger body 1 also can comprise as multistage heat exchangers such as two sections, four sections.
High-temperature region heat exchanger 4 also can have more than one section or two sections.
Heat exchanger body 1 also can be the existing one-part form structure of industry, such as having only high temperature section 41, in 5 three sections on middle-temperature section 42 and the low-temperature space heat exchanger one section, be two tube sheets before and after heat exchanger body 1 only has, before, be communicated with heat exchanger tube between the back tube sheet, the front end of heat exchanger tube wears the place ahead to front tube sheet, be filled with heat-barrier material between the pipe of the heat exchanger tube in front tube sheet the place ahead, the front end of heat exchanger body 1 is a gas approach, the rear end is an exhanst gas outlet, the rear portion of the housing of heat exchanger body 1 is provided with the shell side imported equipments and parts 9 that communicate between pipe with heat exchanger tube, and the front portion of the housing of heat exchanger body 1 is provided with the shell side spout member 11 that communicates between pipe with heat exchanger tube.
