Abstract
The utility model relates to a heat exchanger, especially suitable for cooling liquids such as asphalt, etc., with high viscosity and easy coagulation. The utility model is composed of an inner pipe and an outer sleeve pipe. The utility model is characterized in that the outer sleeve pipe is a cooling medium tank body which can transfer the heat by means of the cooling media such as the circulating cooling water, etc. The inner part of the inner pipe with a big caliber is provided with a heating medium pipe which is used for heating by means of the heat media such as the steam, etc., which is convenient to clear the asphalt which is remained or blocked in the inner pipe. The utility model has the advantages of strong applicability, simple structure, easy fabrication, less investment, low energy consumption, and convenient maintenance.
Description
The utility model relates to a kind of fluid temperature reduction equipment, belongs to heat exchanger, is specially adapted to the high thick liquid cooling that pitch etc. condenses easily.
The pipe heat exchanger of prior art is made up of the interior pipe of different tube diameters and outer tube.The outer wall of outer tube often is welded with radiating fin, is used for strengthening conducting heat.Chinese patent 90103413.4 and 91227483.2 discloses this heat exchanger.At the fluid of good fluidities such as water and do not worry the occasion of condensing, the heat exchanger of prior art is widely used.And just inapplicable for the high thick liquid that condenses easily, for example, the asphalt moulding packaging production line must be after cooling system be reduced to suitable temperature with hard pitch, and packing containers such as the paper bag of packing into, polybag, wooden line case are convenient to transportation, construction.The viscosity height of pitch, flowability was very poor when temperature was lower than 120 ℃, and quick setting very when temperature is lower than 100 ℃ is residual or stop up pipe in the heat exchanger, is difficult to cleaning.Therefore, to be that design is a kind of can make the cooling of high thick liquid to the purpose of this utility model, and can be controlled at suitable temperature and make it noncondensing, even condense or remain in interior pipe, still can make its fusing, the heat exchanger of being convenient to clear up is as the cooling system of high thick liquid such as pitch.
The purpose of this utility model is that the technical scheme by following structure realizes: place cold medium cell body with pipe in the heavy caliber, another thermal medium conduit is inserted interior pipe, constitutes heat exchanger of the present utility model.The outer wall of interior pipe can be welded with radiating fin, strengthens conducting heat.Flow through when being dipped in the interior pipe of the cell body that has cold medium such as recirculated cooling water when the contour thick liquid of pitch,,, reach the purpose of cooling the heat transferred recirculated cooling water by tube wall and radiating fin.If heat exchanger quits work, or the low excessively pitch that makes of Yin Wendu is residual so that in condensing in during pipe, thermal medium such as steam can be imported the thermal medium conduit in the pipe in placing, and heat residual or condenses in thick liquid in the interior pipe, makes its outflow, to clear up interior pipe.
Adopt heat exchanger of the present utility model, solved the heat exchange of thick liquid, and can clear up residual or condense in the thick liquid in the pipe in the heat exchanger, applicability is strong, and simple in structure, and is easy to manufacture, small investment, and energy consumption is low, and is easy to maintenance.
Accompanying drawing is a heat exchanger of the present utility model.
Below in conjunction with embodiment heat exchanger of the present utility model is done further statement:
See accompanying drawing.The heat exchanger of present embodiment is made up of interior pipe (4), cold medium cell body (9) and thermal medium conduit (1).
Interior pipe (4) is made by steel pipe, places in the cold medium cell body (9).The two ends of interior pipe (4) are welded with flange (3), are convenient to connect with pitch transmission pipeline or other heat exchanger.The outer wall of interior pipe (4) is welded with axial radiating fin (8), to strengthen heat transfer.Interior pipe (4) outer wall of present embodiment is welded with a radiating fin every 45 °, and fin is high 100 millimeters, and is wide 3 millimeters.Be provided with sentinel hole (6) on the top of interior pipe (4), and, can open situation in the observation tube in case of necessity with the flange sealing.The bottom of interior pipe (4) is provided with mudhole (12), also with the flange sealing, can open in case of necessity as maintenance and blowdown usefulness.
Cold medium cell body (9) can be made cartridge type or difformity such as box, and present embodiment is box cell body, uses welded steel plate.The bottom of cell body (9) is provided with stinger (13), in order to support interior pipe (4), makes it placed in the middle in cell body (9).Water inlet (7) places the top of cell body (9), and water inlet pipe (14) is through the other bottom of stretching into cell body (9) of interior pipe (4).Both sides in cell body (9) are provided with overflow plate (10) and delivery port (11).Recirculated cooling water is introduced from water inlet (7), and through water inlet pipe (14), to two side inflow cell bodies (9), when water level in the cell body (9) was higher than overflow plate (10) height, cooling water flowed out through delivery port (11) from cell body (9) bottom.Box cell body (9) is used cover closure, and cover plate can be made several piece, is convenient to dismounting.Cover plate is provided with window (5), at ordinary times sealing.
Thermal medium conduit (1) is made much smaller than the steel pipe of interior pipe (4) by bore, is placed on the position of leaning on the bottom in the interior pipe (4), and is parallel with interior pipe (4).Conduit (1) two ends are welded with flange (2), are convenient to be connected with the thermal medium transfer line or with other heat exchanger.After heat exchanger quits work, the interior residual asphalt of interior pipe (4), or pitch condenses, and when managing (4) in stopping up, can import steam, adds heated bitumen, so that pipe (4) in the cleaning.
When the heat exchanger of present embodiment moves, place as accompanying drawing, thereby the base support need be arranged.
200 millimeters of interior pipe (4) internal diameters of present embodiment, long 5000 millimeters.(9) 5000 * 1200 * 800 millimeters of box cell bodies.37 millimeters of conduit (1) internal diameters, long 5000 millimeters.When pitch by heat exchanger in the flow of pipe (4) when being 25 tons/hour, suitably regulate circulating cooling water flow, can descend 8～10 ℃ through the asphalt temperature of heat exchanger.Therefore, for the about 150 ℃ hard pitch of cooling, need the heat exchanger series operation of three present embodiments, temperature can descend 25～30 ℃, makes that the pitch after the heat exchanger package cooling is 120～125 ℃, satisfies the temperature requirement when packing packing container into.If need enlargement discharge, available some groups of heat exchanger parallel runnings.
