Abstract
One heat exchange connection 1 comprises that the interior pipe 2 of a flanged connector 3 and 4 is to import dye liquor to container handling.Coaxitron 5 is around the outer wall of pipe 2 and at a distance of certain distance, and it forms the space 6 that the end is closed with the outer wall of pipe 2, and is provided with connector 9 and 10, thereby can infeed or therefrom exhaust steam or water to space 6.Pipe 11 around pipe 5 and with its at a distance of certain distance, it forms space 12 with the outer wall of pipe 5, pipe 11 is the outer walls sealing with pipe 5 at its end position 13 and 14 places, also is provided with connector 15 and 16 in the space 12, can pass through space 12 thereby discharge dye liquor.
Description
The present invention relates to heat exchange, particularly the heat exchange between treat liquid and heating or the cooling liquid.The present invention is specially adapted to, although be not exclusively used in, by the temperature of use steam increase dye liquor and by making water reduce the temperature of dye liquor.
The known tube that uses in mode of heating bringing the heat of steam into dye liquor, or is taken away heat by making water pass the pipe in the device in the type of cooling from dye liquor.
In the former method, there is a kind of bottom that one big coil pipe is set at dye vat.Yet this method has following shortcoming.
1. coil pipe must be positioned at the minimum zone of flow stream velocity of machine, thereby heat exchanger effectiveness is minimum, thereby needs big heat exchange surface;
2. coil pipe has increased the height requirement of dye vat since around the spiral of coil pipe or between have the spaces that do not occupied in a large number, thereby make most of above-mentioned height all waste.This will increase the liquid measure in the machine and lower efficiency;
3. the thing that dyes if desired is for parcel and dye liquor flow velocity are low closely, and then the liquid that contacts with heat(ing) coil will overheat even seethe with excitement, and makes liquid rise to the top that is almost inactive liquid in dye vat, thereby produces potential danger;
4. the overtemperature of Jian Suing has bad effect to dyestuff, causes that promptly dyestuff fades, thereby makes the painted mistake of pollutant shallow or depart from tone, this be because the special composition in the prescription of dye liquor complexity than other composition more to responsive to temperature.
Known also have a kind of outer heat-exchange device of dye vat that is positioned at, it comprises that many parallel wherein streams have the pipe of dye liquor, these pipes are placed in the container in such a way, promptly allow steam that is used to heat or the water that is used to cool off contact with the outer surface of pipe.This device has sizable input and output loss, and is used for making liquid to pass pipe quite a few ability of pump.
Also can use a kind of opposite configuration, wherein steam or cooling water pass pipe, and dye liquor centers on them and is arranged in container.But all schemes that propose are previously attempting to keep all to have serious defective aspect the high speed of heat-exchange medium.
According to the present invention, between container handling and pump, be provided with a heat exchange connection, can between container handling and pump, flow by its treat liquid, this connector comprises coaxial flowing and return conduit, between them, be provided with a ring duct, wherein stream has heating or cooling liquid, so that flowing liquid in mobile and return conduit is heated or cools off.
Thereby connector is preferably a pair of channel vertical cylindrical heat exchanger.
It is circular that internal flow or return conduit are preferably, and flows outside or return conduit are annular.
Preferably inner catheter is a flow-catheter, and outer catheter is a return conduit.The size of flow-catheter makes wherein treatment fluid not have the pressure drop that can measure when pump flows to container handling, and the pressure loss in the outer return conduit also can reduce to minimum by good design, in any case less than existing design.
For any given temperature-rise ratio example, flow through each time or temperature that the fluid that returns is entrained only is half of existing design, thereby can improve the stability of dyestuff.
Temperature difference around circulating system also can equally with the pressure loss be reduced to minimum.
Also can flow outside or the outside of return conduit is provided with a ring duct that passes through for heating or cooling liquid again.
Also can flow or return conduit is done and circularized interior, so that dye liquor is by first annular space, heating or cooling fluid flow in an outer ring space, and the recycle stream of treatment fluid is by an outer ring space again.The advantage of this structure is can increase the area of heating surface and can not reduce to flow through the heating or the flow stream velocity of cooling surface.
The present invention will be described by way of example with reference to the accompanying drawings, in the accompanying drawing:
Fig. 1 is the vertical cross-section diagram according to heat exchange connection of the present invention;
Fig. 2 is the plane corresponding to Fig. 1;
The profilograph of Fig. 3 for being intercepted along A-A line among Fig. 2;
Fig. 4 is the sectional view of the amplification that intercepted along B-B line among Fig. 3.
Referring to accompanying drawing, label is that 1 heat exchange connection comprises pipe 2 in, and there is a flange coupling connector 3 interior pipe upper end, and there is a connector 4 its lower end.In pipe 2 to container handling input dye liquor or therefrom discharge dye liquor, one in container handling and the connector 3 and 4 links to each other, and another links to each other with transfer pump.
Coaxitron 5 is around the outer wall of pipe 2 and at a distance of certain distance, and it forms space 6 with the outer wall of pipe 2.Space 6 is closed in its end, and pipe 57 and 8 seals with pipe 2 outer wall in the position.6 lower end is provided with a connection piece 9 in the space, and 6 upper end is provided with a connection piece 10 in the space, thereby can infeed steam or water and therefrom discharge to space 6 by connector 9 and 10.
As can be seen from Figure 4, the dyestuff that enters that flows in pipe 2 is in heat exchange relationship with steam that flows or water on the whole inner wall surface of pipe 2 in space 6.The discharge dyestuff that flows in space 12 is in heat exchange relationship with steam that flows or water on the whole outer surface of pipe 5 in space 6.
