The utility model relates to a secondary heat exchanger, which comprises two heat exchange devices. The two heat exchange devices are vertically placed; a connection pipe is arranged between the two heat exchange devices; a first seal head is arranged on the heat exchange device placed at the upper part; a first outlet is formed at the top part of the first seal head; a second seal head is arranged below the heat exchange device placed at the lower part; and a first inlet is formed at the bottom part of the second seal head. The secondary heat exchanger has the advantages of simple structure, low energy consumption and high work efficiency.
Description
Technical field
The utility model relates to a kind of secondary heat exchanger.
Background technology
Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies critical role aborning.General heat exchanger is to be wound with pipeline in the periphery of container, and gas or liquid that needs are cooled off are contained in the container, injects refrigerant (as cooling water, salt solution etc.) then in pipeline, such heat exchange DeGrain, and need carry out long heat exchange, waste energy, efficient is low.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, and the secondary heat exchanger of a kind of simple in structure, energy savings, high efficiency is provided.
The purpose of this utility model is achieved through the following technical solutions: secondary heat exchanger, comprise two heat-exchanger rigs, two heat-exchanger rigs are placed up and down, be provided with tube connector between two heat-exchanger rigs, place the heat-exchanger rig of top to be provided with first end socket, the top of first end socket is provided with first outlet, places the heat-exchanger rig of below to have second end socket, and the bottom of second end socket is provided with first import.
Further improvement of the utility model is: each heat-exchanger rig comprises the cylinder type hollow shell, the outer surface of outer cover middle part is provided with two symmetrically arranged bearings, outer casing underpart is provided with second import, shell upper is provided with second outlet, second import and second outlet are staggered relatively, the upper surface and the lower surface of shell are equipped with tube sheet, tube sheet is provided with a plurality of through holes, be provided with a plurality of heat-exchange tubes between two tube sheets, each heat-exchange tube all places enclosure, and the two ends of each heat-exchange tube all are inserted in the through hole on the tube sheet, are provided with a plurality of deflection plates by the deflection plate support in the shell, each deflection plate is placed up and down, places about two adjacent deflection plates.
Further improvement of the utility model is: the bottom of shell another side is provided with drain, and the drain and second import are staggered relatively.
The utility model compared with prior art has the following advantages:
The utility model adopts two heat-exchanger rigs, can carry out heat exchange by two kinds of refrigerants, the temperature exchange of material in the shell can be arrived temperature more accurately, refrigerant carries out the flow direction of serpentine in the enclosure, can fully contact with the material in the shell, the efficient height of heat exchange, and two also removable separately uses separately of heat-exchanger rig, the service efficiency height.
