Abstract
The invention relates to a heat exchanger. The heat exchanger comprises a housing, pipe boxes, pipe plates, baffle plates, pull rods and a heat exchange pipe, and is characterized by further comprising liquid gathering housings and outer pipe plates, wherein the liquid gathering housings are arranged between the housing and the pipe boxes; exhausting openings are formed in the upper ends of the liquid gathering housings; liquid discharging openings are formed in the lower ends of the liquid gathering housings; the outer pipe plates are arranged at the joints of the pipe boxes and the liquid gathering housings; the end heads of the heat exchange pipe penetrate through the outer pipe plate, and are communicated with the pipe boxes. The heat exchanger has the advantage that the heat exchanger can prevent leakage.
Description
Technical field
The present invention relates to a kind of heat exchanger, particularly relate to the shell-and-tube heat exchanger in a kind of Chemical Manufacture.
Background technology
In Chemical Manufacture, shell-and-tube heat exchanger is one of the most common unit operating equipment, and it comprises housing, bobbin carriage, tube sheet, deflection plate, pull bar and heat exchanger tube; Respectively connect a bobbin carriage at housing two ends, be provided with a tube sheet in the junction of housing and bobbin carriage, arrange some deflection plates in the housing between the tube sheet at housing two ends, pull bar one end is connected with tube sheet, and the other end is connected with deflection plate; The deflection plate that heat exchanger tube is arranged on housing two ends is between two tube sheets; In actual mechanical process, heat exchanger tube and the tube sheet junction of heat exchanger are the most easily leaked; For ensureing bonding strength and the sealing property of tube-to-tube sheet connection, various method of attachment can be adopted, but these methods all can not ensure absolutely not to leak; Even if the water pressure test, air-tight test are completely qualified, but in operation due to the synergy of temperature, pressure and medium, the particularly fluctuation of pressure, temperature or suddenly change (as: open, stop, upset operation), often makes pipe and pipe junction produce leakage in various degree; A small amount of leakage affects not quite in general chemical process, can allow; But in specific occasion, these leakages can make shell journey medium mixedly appear serious or catastrophic failure.
Summary of the invention
For above-mentioned shortcoming, the object of the present invention is to provide a kind of heat exchanger of energy Leakage prevention.
Technology contents of the present invention is, a kind of heat exchanger comprises housing, bobbin carriage, tube sheet, deflection plate, pull bar and heat exchanger tube, it is characterized in that it also comprises poly-liquid housing and outer tube plate; Between housing and bobbin carriage, be provided with a poly-liquid housing, be provided with exhaust outlet in poly-liquid housing upper end, be provided with leakage fluid dram in poly-liquid housing lower end; Outer tube plate is arranged on the junction of bobbin carriage and poly-liquid housing; The termination of heat exchanger tube is communicated with bobbin carriage through outer tube plate.
The present invention is compared with prior art had is a little: owing to being provided with a poly-liquid housing and increasing by an outer tube plate between housing and bobbin carriage, the junction of heat exchanger middle shell and bobbin carriage is made to have the anti-leak of twice, leak gas-liquid and gather discharge after in poly-liquid housing, the present invention has the effect of good Leakage prevention thus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Specific embodiment
As shown in Figure 1, a kind of heat exchanger, comprises housing 1, bobbin carriage 2, tube sheet 3, deflection plate 4, pull bar 5 and heat exchanger tube 6, it is characterized in that it also comprises poly-liquid housing 7 and outer tube plate 8; Between housing 1 and bobbin carriage 2, be provided with a poly-liquid housing 7, be provided with exhaust outlet 7.1 in poly-liquid housing 7 upper end, be provided with leakage fluid dram 7.2 in poly-liquid housing 7 lower end; Outer tube plate 8 is arranged on the junction of bobbin carriage 2 and poly-liquid housing 7; The termination of heat exchanger tube 6 is communicated with bobbin carriage 2 through outer tube plate 8.
