Description
Technical field
The utility model relates to a kind of light oil preheater, belongs to Sodium Cyanide Production equipment technical field.
Background technology
Light oil preheater is the energy-conservation visual plant with improving production capacity of ammonia oil cracking process Sodium Cyanide Production.It is the heat transmission equipment utilizing temperature difference between high-temperature furnace gas and liquid light oil, and cracking furnace gas both can have been made to drop to the requirement temperature of technique, makes again light oil temperature before entering pyrolysis furnace improve simultaneously, thus reaches the object enhancing productivity and reclaim heat energy.
Common light oil preheater is sleeve type structure, is generally two-layer or three layers, horizontally puts, and is not about 10 to 20 meters not etc., takes up an area larger; Because equipment is longer, phenomenon of expanding with heat and contract with cold is comparatively large to equipment damage, need often keep in repair; Simultaneously because material is stored more in equipment, the time of staying is long, raw material carbonization seriously, i.e. blocking pipe but also waste raw material; Particularly terminal valve is more, in the process that parking is driven again, if misoperation, staggers and opens by mistake valve, easily cause blast casualty accident.
Utility model content
For above deficiency, the utility model provides a kind of heat exchange efficiency high and the light oil preheater of safety and stability.
The utility model is implemented by the following technical programs: a kind of light oil preheater, formed by three layers of sleeve combination of vertical placement, described three layers of sleeve pipe are respectively center sleeve, intermediate casing and outer layer sleeve from inside to outside, wherein the space delamination between center sleeve and outer layer sleeve is formed first passage and second channel by intermediate casing, first passage is communicated with bottom second channel, draw high-temperature furnace gas entrance on the top of first passage, draw high-temperature furnace gas outlet on the top of second channel; The inside of described center sleeve is cylindrical cavity, the inside cavity in the form of a ring of described intermediate casing, by cross-layer channel connection between the top of described center sleeve and the top of intermediate casing, draw light oil entrance in the bottom of center sleeve, draw light oil outlet in the bottom of intermediate casing.
The bottom space of described outer layer sleeve forms cone space, being provided with the discharge gate for discharging solid particulate matter, being conducive to the removal of entrained particles shape ashes in furnace gas in the bottom of cone space.
The inside cavity in the form of a ring of described outer layer sleeve, which is provided with cold water inlet and hot water outlet, when being filled with cold water in outer layer sleeve, conveniently can reduce the temperature of furnace gas.
Described cross-layer passage can not affect the operation of intermediate layer material while the transfer of material interlayer, and this channel cross-section is can rectangle, circle or other shapes.
Compared with prior art, the utility model has following advantage: 1, the utility model is the novel vertical light oil preheater integrating preheating, cooling, ash disposal, owing to adopting vertical installation, therefore not only can save floor occupying area, and be conducive to the removal of entrained particles shape ashes in furnace gas; 2, the utility model can meet technological requirement preferably, and not only heat exchange efficiency is high, and can realize continued operation, failure rate is low, has good security simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
A kind of light oil preheater as illustrated in fig. 1 and 2, formed by three layers of sleeve combination of vertical placement, described three layers of sleeve pipe are respectively center sleeve 13, intermediate casing 4 and outer layer sleeve 3 from inside to outside, wherein the space delamination between center sleeve 13 and outer layer sleeve 3 is formed first passage 2 and second channel 5 by intermediate casing 4, first passage 2 is communicated with bottom second channel 5, draw high-temperature furnace gas entrance 1 on the top of first passage 2, draw high-temperature furnace gas outlet 7 on the top of second channel 5; The inside of described center sleeve 13 is cylindrical cavity, the inside cavity in the form of a ring of described intermediate casing 4, be communicated with by cross-layer passage 8 between the top of described center sleeve 13 and the top of intermediate casing 4, the cross section of described cross-layer passage 8 is rectangle or circle, draw light oil entrance 11 in the bottom of center sleeve 13, draw light oil outlet 10 in the bottom of intermediate casing 4; The inside cavity in the form of a ring of described outer layer sleeve 3, which is provided with cold water inlet 14 and hot water outlet 9, and the bottom space of described outer layer sleeve 3 forms cone space 6, is provided with the discharge gate 12 for discharging solid particulate matter in the bottom of cone space 6.
Operation principle: high-temperature furnace gas enters first passage 2 from high-temperature furnace gas entrance 11 and runs downwards, reverses after going out first passage 2, upwards run through second channel 5 in bottom, finally goes out preheater through high-temperature furnace gas outlet 7.In the process, entrained solid particle comes together in bottom pyramidal space 6, is regularly drained in collecting tank by discharge gate 12; Heating object material---liquid light oil adds from light oil entrance 11, centrally sleeve pipe 13 upwards runs and is heated simultaneously, intermediate casing 4 is entered through cross-layer passage 8 when being up to the top of center sleeve 13, because intermediate casing 4 is in the centre of first passage 2 and second channel 5, therefore when liquid light oil can because being heated violent and rapid temperature increases gasification when through first passage 2 and second channel 5, finally completing preheating from outlet at bottom 10 goes out; In order to reduce furnace gas temperature further, outer layer sleeve 3 passes into recirculated water, and cold water enters from the cold water inlet 14 of bottom, and hot water is discharged from the hot water outlet 9 on top.
