Abstract
The utility model relates to a shell-and-tube heat exchanger, which is suitable for a gas-gas heat exchanging system or a gas-liquid heat exchanging system, and the shell-and-tube heat exchanger can adjust the heat exchanging area. The shell-and-tube heat exchanger is additionally provided with an area adjusting device on the inlet (or an outlet) air chamber of the tube pass of the ordinary heat exchanger (the cloth lacking tube of the double circles); the adjusting device is composed of an adjusting block, an adjusting screw rod (or other mechanical mechanisms), a balancing tube, and a transmission system. Through the switching to the conducting quantity of the tube array of the heat exchanger, the purpose of regulating the heat exchanging area can be obtained. When the tube array is gradually plugged, the heat exchanging area can gradually decrease; inversely, when the tube array is conducted with the gradual conduction, the heat exchanging area can gradually increase.
Description
The utility model relates to a kind of gas that is adapted to---gas heat exchange or gas---shell-and-tube heat exchanger of liquid heat-exchange system especially can in use be regulated the heat exchanger of heat exchange area.
At present, its heat exchange area of known heat exchanger is a fixed value manufacturing and designing after finishing, in use immutable, though structurally improve to some extent, develop into high type (adopting two circles to lack stringing) by plain edition (heat exchanger tube is covered with tube sheet), but its heat exchange area can not be regulated according to the variation needs of process conditions.
The purpose of this utility model provides a kind of heat exchanger, and it not only has the heat-transfer character of known heat exchanger, and can regulate according to the variation heat exchanging area of process conditions, produces needs to satisfy, and makes production process be in optimum state.
The purpose of this utility model is achieved in that at the import of common heat exchanger (two circles lack stringing) tube side (or outlet) air chamber has increased an area adjusting device, adjusting device is made up of regulating block, adjusting leading screw (or other mechanical mechanism) balance pipe and transmission system, and its typical structure as shown in Figure 1.Conducting quantity by heat exchanging device tubulation is switched, and reaches the purpose of regulating heat exchange area.When tubulation during by shutoff gradually, the tubulation number of conducting reduces gradually, and heat exchange area is corresponding to be reduced gradually.Otherwise when by the tubulation of shutoff during by conducting gradually, heat exchange area is corresponding to be increased gradually.Constant substantially in order to accomplish after tubulation is by shutoff, to keep the gas flow rate in the heat exchanger tube, set up balance pipe, with the shutoff of tubulation or the gas speed after the shutoff of conducting cooperation balance tubulation, thereby realize not only regulating heat transfer area but also do not change the purpose of managing interior gas speed.
Owing to adopt such scheme, make the in use unmodifiable present situation of heat exchanger area be changed, and its Principles of Regulation are simple and clear, apparatus structure is simple, makes in operation control and has compared tangible advantage with common heat exchanger.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is an exemplary block diagram of the present utility model.
Fig. 2 is the vertical view (front view is identical with Fig. 1) of another embodiment, adopts the turnover plate type regulating block, the parallel four-bar linkage adjustment structure.
Leading screw 8. transmission systems 9. balance pipes 10. shell side gas feeds (or outlet) 11. tube side gas vents (or import), 12. connecting rods, 13. bearing pin 14. cranks, 15. turnover plate type regulating blocks (connecting firmly with axle) are regulated in 3. deflection plate 4. 5. tube side gas feeds of shell side gas vent (or import) of 1. heat exchanger shells, 2. tubulations (two circles lack stringing) among the figure (or outlet) 6. regulating block 7.
The Principles of Regulation of the utility model heat exchanger are to be means with shutoff and conducting heat exchanger tube (tubulation), utilize the increase of heat exchanger tube conducting quantity or reduce the purpose that realizes that heat exchange area increases or reduces.And utilize gas speed in the balance pipe balance pipe.Below be specifying based on embodiment of the present utility model.
Embodiment 1:
As shown in Figure 1.Adopt slide block type regulating block leading screw adjustment structure, regulating block is respectively established one in the both sides that two circles lack stringing.The size of regulating block determines that by the adjustable range of designing requirement size wide adjusting range more is big more, and vice versa.Minimum dimension is exceeding the complete shutoff of the balance mouth of pipe.Leading screw adopts two ends rotation direction inverse structure, can be designed to monofilament thick stick or mariages thick stick according to the difference of heat exchanger.When drive unit drives the leading screw rotation, regulating block inside simultaneously (or outwards) is slided.When inwardly sliding, with the heat exchanger tube shutoff, simultaneously balance pipe is opened gradually gradually, heat exchange area is diminished gradually, when outwards sliding, will simultaneously balance pipe be closed gradually by the heat exchanger tube conducting of shutoff gradually.When balance pipe is closed, the whole conductings of all heat exchanger tubes.This moment the heat exchange area maximum.When balance pipe is all opened, reached at most by the heat exchanger tube number of shutoff, this moment the heat exchange area minimum, whole adjustment process is for carrying out continuously, heat exchanger can a bit working arbitrarily in adjustable range.
Embodiment 2:
Identical with embodiment 1 structure, but do not establish balance pipe, its action principle is also identical with embodiment 1 with adjustment process, but owing to there is not gas flow rate in the balance pipe adjustable pipe, in adjustment process, cause change in resistance by the change of gas speed, the resistance of system is increased, and its effect is compared less better with embodiment 1.
Embodiment 3:
Adopt the turnover plate type regulating block, parallel four-bar linkage adjustment structure, the structure of turnover plate type regulating block adopt the louvre type structure to be made up of several little turnover panels as shown in Figure 2.Tubulation district turnover panel becomes 90 ° of angles to install with balance pipe place turnover panel.It is means that its action principle remains with shutoff and conducting heat exchanger (tubulation), utilizes the increase of heat exchanger tube conducting quantity or reduces the purpose that realizes that heat exchange area increases or reduces.And utilize gas speed in the balance pipe balance pipe.Connecting rod (12) connects with transmission system (8).When the transmission system drives link motion, drive crank (14) and rotate around the axle that is fixed on the adjustable plate (15), owing to be designed to nonrotational the connection between crank and the axle, spool rotate with adjustable plate thereby make.In adjustment process, the range of movement of transmission system is to make adjustable plate to different directions half-twist angle.Because tubulation district turnover panel and balance pipe place turnover panel are installed at an angle of 90, therefore when balance pipe was opened, the turnover panel at tubulation place covered heat exchanger tube just.And when balance pipe was closed, the turnover panel at tubulation place was opened heat exchanger tube again.Thereby realize the purpose of shutoff (renovating) or conducting heat exchanger tube, make heat exchange area obtain adjusting, because structure is limit, adjustment process can not realize serialization.Multipotency is divided into the 2-4 group and controls.
Embodiment 4:
Identical with embodiment 3 structures, but do not establish balance pipe, action principle is also identical with embodiment 3 with adjustment process, but can be divided into the 3 more control groups than embodiment.Since there is not the regulating action of balance pipe, identical with embodiment 2, there is the deficiency that SR is increased.
