Detailed description of the invention
Embodiment 1
As shown in Figure 1, 2, a kind of shell-and-tube heat exchanger, including the heat-transfer pipe 3 in the housing of heat exchanger and housing, described biography
The two ends of heat pipe 3 connect an orifice plate 9, the edge of orifice plate 9 and inner walls airtight connection, the through hole phase on two orifice plates respectively
Correspondence, connects a heat-transfer pipe 3 between the through hole that two orifice plates every pair are corresponding, enclosure interior cavity is separated by described orifice plate 9
Becoming air inlet area, heat transfer zone and district three part of giving vent to anger, described air inlet area is provided with high-temperature gas air inlet 1, described in district of giving vent to anger arrange
High-temperature gas gas outlet 5, described heat-transfer pipe 3 is had in heat transfer zone, about heat transfer zone, to be respectively arranged at two ends with cryogenic gas air inlet 4
With cryogenic gas gas outlet 2, described in give vent to anger and be provided with filter screen 8 in district, the edge of described filter screen 8 and give vent to anger district's inner walls even
Connecing, be preferably tightly connected, district's housing bottom of giving vent to anger is provided with oil sump tank 7, and described oil sump tank 7 connects oil exit pipe 6.Described hole
Through hole on plate is at least 6, is uniformly distributed on orifice plate.
Aperture 200 ~ 500 mesh of filter screen 8.Described filter screen is stainless steel filtering net.This aperture ensure that oil droplet is trapped, and
Stainless steel filtering net is readily cleaned, it is not easy to make oil droplet wall built-up, and thermal stability is relatively good.
In the present embodiment, in use, the high-temperature gasification with suspended oil particles from compressor output is natural
Gas A, high-temperature gas air inlet 1 enters in heat exchanger.Now because gas enters into a volume from a thinner pipeline
In bigger heat exchanger, gas flow velocity in heat exchanger can reduce.Further, since the temperature that cryogenic gas air inlet 4 flows into
The heat exchange of relatively low natural gas gas B, A gas temperature reduces, and the suspended oil particles being now blended in A gas drops in temperature
Slowly assemble in the case of low and become big.The gas A become larger when entrained suspended oil particles flows out from heat-transfer pipe, Jing Guowei
Stainless steel filtering net 8 on the right side of orifice plate 9, now gas passes through stainless steel filtering net, and oil particles is intercepted by stainless steel filtering net.Blocked
The oil particles cut converges and forms heavier oil particles, and these heavier oil particles converge to the end of shell under gravity
Portion, and finally trickling oil-feed collecting tank 7.Oil in oil sump tank 7 is collected in oil conservator by oil exit pipe 6 or is directly passed through
Oil return opening returns to the crankcase of compressor.
The filter screen of heat exchanger, can not only realize separating of oil function, and can impurity in filtering appts, in order to avoid impurity
Enter compressor and affect the performance of compressor.This heat exchanger with separating of oil function is mainly used in compressor output gas
The fewer occasion of oil mass.It not only realizes Oil-gas Separation, and system cost is reduced.
