Abstract
The utility model provides a high-efficiency heavy oil and coal tar heat exchange device, and belongs to heat exchange devices. The high-efficiency heavy oil and coal tar heat exchange device comprises a heavy oil pipeline, a coal tar pipeline, a first heat exchanger and a second heat exchanger, wherein the heavy oil pipeline is sequentially connected to pipe passes of the first heat exchanger and the second heat exchanger, and the coal tar pipeline is sequentially connected to shell passes of the second heat exchanger and the first heat exchanger. The high-efficiency heavy oil and coal tar heat exchange device is reasonable in structure, simple to operate, energy-saving and environment-friendly. The actual production proves that fed coal tar subjected to heat exchange can alleviate the load of a coal tar heating furnace to a great degree and also correspondingly reduces the usage amount of fuel gas of the heating furnace. The high-efficiency heavy oil and coal tar heat exchange device is energy-saving and capable of reasonably recycling and fully utilizing available resources and has an obvious protection effect on production environments.
Description
Technical field
The utility model relates to a kind of heat-exchanger rig, particularly a kind of heavy oil and coal tar high-efficiency heat exchanger.
Background technology
In Coal Chemical Industry is produced, find, common tripping device is bad for the separating effect that subtracts top return tank oil-in-water water, causes to subtract top oil and can not directly send outside as the refining charging of reactive system, therefore can ban original device and subtract the pipeline that top oil is sent outside; Again because this pipeline is first to go out device after subtracting top oil/heavy oil interchanger, ban this pipeline can cause subtract in the oil/heavy oil interchanger of top heavy oil cannot heat exchange, make energy loss and waste, heavy oil goes out timer temperature up to 300～320 ℃ simultaneously, to safety in production, bring hidden danger, during to tank field heavy oil tank, also can produce a large amount of glance coals, also to plant environment, bring very large pollution.And the temperature of coal tar before entering tower is generally 100～120 ℃, although original device is provided with coal tar interchanger, can not reach production requirement, need to proceed gas heating, and cost is higher.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of heavy oil and coal tar high-efficiency heat exchanger.
The utility model heavy oil and coal tar high-efficiency heat exchanger, comprise heavy oil pipeline, coal tar pipeline, First Heat Exchanger and the second interchanger, heavy oil pipeline is connected successively with the tube side of First Heat Exchanger, the second interchanger, and coal tar pipeline is connected successively with the shell side of the second interchanger, First Heat Exchanger.
As further improvement of the utility model, the shell side exit end of the second described interchanger is connected with the exit end pipeline of First Heat Exchanger shell side and is provided with valve I.
As further improvement of the utility model, the entrance end of described First Heat Exchanger tube side is provided with valve II, exit end and is provided with the oil-in of valve III, valve II and the oil outlet pipeline of valve III and is connected and is provided with valve IV; The entrance end of the second heat exchanger tube pass is provided with valve V, exit end and is provided with the oil-in of valve VI, valve V and the oil outlet pipeline of valve VI and is connected and is provided with valve VII.
The utility model heavy oil and coal tar high-efficiency heat exchanger, reasonable in design, simple to operate, energy-conserving and environment-protective.Through actual production checking, the feed coal tar after heat exchange has alleviated the load of coal tar-heater to a great extent, also corresponding reduction process furnace fuel gas usage quantity.The utility model save energy, rationally reclaims and takes full advantage of existing resource, and protection production environment successful, and after coming into operation, nearly tens thousand of unit every year can economize on the use of funds.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the heavy oil of the utility model and coal tar high-efficiency heat exchanger, comprise heavy oil pipeline 1, coal tar pipeline 2, First Heat Exchanger 3 and the second interchanger 4, heavy oil pipeline 1 is connected successively with the tube side of First Heat Exchanger 3, the second interchanger 4, and coal tar pipeline 2 is connected successively with the shell side of the second interchanger 4, First Heat Exchanger 3.The shell side exit end of the second described interchanger 4 is connected with the exit end pipeline of First Heat Exchanger 3 shell sides and is provided with valve I 5.The entrance end of described First Heat Exchanger 3 tube sides is provided with valve II 6, exit end and is provided with the oil-in of valve III 7, valve II 6 and the oil outlet pipeline of valve III 7 and is connected and is provided with valve IV 8; The entrance end of the second interchanger 4 tube sides is provided with valve V 9, exit end and is provided with the oil-in of valve VI 10, valve V 9 and the oil outlet pipeline of valve VI 10 and is connected and is provided with valve VII 11.
Use into; first the pretreated coal tar of original device enter First Heat Exchanger 3 Reentry heating stoves; through increase pipeline rear feeding flow process, change coal tar into and be introduced into the second interchanger 4; after First Heat Exchanger 3 heat exchange, enter process furnace again; after changing, make coal tar oil temperature bring up to 200～250 ℃ from 100～120 ℃; and heavy oil temperature after heat exchange goes out device is down to 220～260 ℃; alleviated the load of process furnace; reduced process furnace fuel gas usage quantity; protect plant environment, also guaranteed safety in production.
