Description

The liquefied petroleum gas water-cooled heat exchanger

Technical field

The utility model relates to a kind of closed not contaminated and liquefied petroleum gas water-cooled heat exchanger with high heat exchange rate simple in structure.

Background technology

Liquefied petroleum gas (Liquefied Petroleum Gas is called for short LPG) is the product behind the light oil cracking, after finishing cracking, be-45 ℃ stable liquid state, and the general trough for used balls of the mode of its storage is stored, under the normal temperature state, if-45 ℃ liquefied petroleum gas directly enters the ball groove, the temperature difference that it is acute excessively, to make the structure of ball groove because of sharply expanding with heat and contract with cold, and cause producing the crack, and then cause the leakage of liquefied petroleum gas, this has sizable threat to public safety, therefore before liquefied petroleum gas enters the ball groove of storage, all can pass through the processing that heats up earlier, with the temperature difference of shortening with the ball groove, and the processing that heats up generally is with heat exchanger liquefied petroleum gas to be warming up to about about 4 ℃, so just can guarantee the safety of ball groove structure.

See also Fig. 1, the heat exchanger that present liquefied petroleum gas more generally adopts is to feed liquefied petroleum gas with an inlet tube 1, on inlet tube 1, be communicated with several circuitous manifolds 2 again, send liquefied petroleum gas with outlet 3 more at last, cooling water is then sprayed the outside of body by the top in the shower mode, in order to increase the area that contacts with cooling water, each manifold 2 sets up in circuitous mode of twining, and reaches the purpose of cold and hot exchange.When the outside sprinkling of body cooling water, squirt near zone in order to prevent that cooling water is excessive, need to erect one around interchanger partition wall 4, this kind mode is not only installed comparatively trouble, and the efficient of its heat exchange is also not good, and the intensity of manifold 2 more seems not enough because of caliber is less, because manifold 2 is exposed, thus be vulnerable to the external pollution corrosion, and when maintenance, therefore manifold 2 remains to be improved because of circuitous winding also is difficult for doing maintenance of clean-up.

Summary of the invention
