Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
See Fig. 1, a kind of conversion stripper self-heating apparatus, include stripper 1, conversion gas separator 6 and heat exchanger 10, the bottom of gas tower 1 is connected with condensate outlet pipe 3, the bottom of gas tower 1 is connected with steam inlet tube 2, the top of gas tower 1 is connected with resolution gas outlet 5, heat exchanger is respectively equipped with condensate liquid to enter, the port of export and desalted water enter, the port of export, top in stripper 1 is provided with porous endless tube spray thrower 12, the front end of condensate outlet pipe 3 is connected with the first control valve group 7 and force (forcing) pump 9 that are in parallel, first control valve group 7 is compiled in a place with the outlet of force (forcing) pump 9 and is connected with the condensate liquid entrance point of heat exchanger 10, the top of conversion gas separator 6 is connected to conversion gas inlet tube 13 and desalted water inlet tube 14, the top of conversion gas separator 6 is provided with conversion gas outlet 8, the bottom of conversion gas separator 6 is connected with desalted water outlet 4, and the front end of desalted water outlet 4 is connected with the desalted water entrance point of heat exchanger 10, be connected with porous endless tube spray thrower 12 after the desalted water port of export connection desalted water filter 11 of heat exchanger 10.
In the present invention, the front end of resolution gas outlet 5 is connected to torch gas house steward.
The second control valve group 15 is connected with between desalted water outlet and the desalted water entrance point of heat exchanger 10.
Hypomere system pipe network is led in conversion gas outlet 8.
Desalted water filter includes two set filters be in parallel.
Below in conjunction with accompanying drawing, the present invention is further illustrated:
In the present invention, porous endless tube spray thrower 12 selects the stainless steel pipes of φ 89 × 8mm to make endless tube, and circumferencial direction evenly beats 4mm aperture immediately below endless tube bottom, inside endless tube, beat same aperture along 45 ° of circumferencial directions simultaneously, breach pipe spray thrower is replaced with porous endless tube spray thrower 12, after steam is opened, because gas is at the even gas distribution in endless tube inner periphery direction, washing away of gas can be reduced like this, avoid occurring the easy washed out phenomenon of breach pipe spray thrower, tower top desalted water water spray effect can be improved simultaneously, improve the heat exchange effect of inner-tower filling material.
For keeping the Srteam Stripping effect of stripper 1, must add the steam of 1.3MPa continuously to stripper, such steam consumption is large.Because the stripper temperature after adding through steam is 190 °, and the temperature of the desalted water sent here from conversion gas separator 6 is 30 °.The present invention increases heat exchanger 10, filter 11 and force (forcing) pump 9.The high temperature condensate liquid of being discharged by tower body like this improves the temperature of the desalted water sending into tower body, through adjusting, the temperature sending into the desalted water of tower body can be increased to 80 ° by 30 °, per hour can steam saving about 20Kg, so just suitably can adjust the increment of the steam of 1.3MPa, energy-saving effect is good, and economic benefit is considerable.For stripper liquid level, the wayward problem with sending condensate liquid difficulty outside, can be replaced by the pipeline of DN100mm by DN50mm by the condensate outlet pipe 3 at the bottom of tower, increases circulation effect; Add on condensate outlet pipe 3 simultaneously and join force (forcing) pump 9(flow a: 20m3/h, lift: 70m), according to stripper internal pressure and production concrete condition, timely and effectively condensate liquid can be delivered to vaporization post by force (forcing) pump 9; In addition, condensate outlet pipe 3 increases simultaneously and joins the first control valve group 7, remote transfer signal is connected on microcomputer, with microcomputer prison dish and on-the-spot magnetic flap level gauge with the use of, realize on-line control tower body liquid level, send condensate liquid in time.
The top of conversion gas separator 6 is respectively arranged with conversion gas inlet tube 13 and desalted water inlet tube 14, and effect relies on desalted water washing conversion gas; Conversion gas is delivered to hypomere system pipe network by conversion gas separator 6 conversion gas outlet 8.By operating mode reasonable employment first control valve group 7 and force (forcing) pump 9, thus reasonable adjusting condensate liquid.By heat exchanger 10, the condensate liquid that condensate outlet pipe 3 is sent is heated desalted water, improve the temperature into tower desalted water; Two groups of desalted water filters 11 can realize desalted water and switch cleaning online, thus improve the service condition of stripper 1.
Original stripper seedpod of the lotus shower nozzle 4 and steam inlet tube 2 are all cancelled, and be set to porous endless tube spray thrower 12, object is the spraying effect of the desalted water improved into tower, promotes that gas-liquid exchanges, ensures the stable operation of stripper 1.
