Specific embodiment

Such as Fig. 1, the hydrogenation reactor heating warm-up cycle device of the utility model, mainly by venturi circulating pump 2, chuck 1st, drum 3, hydrogenation reactor 5, lime set supplement pipe 4 and liquid level gauge 8 form, and wherein venturi circulating pump 2 is equipped with steam inlet 23rd, lime set entrance 21 and mixture export 22, as shown in Figure 2；Uniformly divide around chuck 1 there are four being set in 1 lower end side of chuck The steam entry 11 and condensate outlet of cloth, upper surface are equipped with steam (vapor) outlet；Drum 3 is equipped with steam inlet 23 and lime set goes out Mouthful.

Chuck 1 is looped around 5 surrounding of hydrogenation reactor, and the side setting liquid level gauge 8 and fluid guidance port 7, fluid guidance port 7 of chuck 1 are set It puts in 1 side lowest point of chuck.The steam entry 11 of chuck 1 is connect with the mixture export 22 of venturi circulating pump 2, The condensate outlet 12 of chuck is connected to the energy liquid entrance of venturi circulating pump 2, and the steam inlet 31 of steam (vapor) outlet and drum connects, The condensate outlet 32 of drum is then connected to the lime set entrance 21 of venturi circulating pump 2, while in the steam entry 11 of chuck 1 It puts and is additionally provided with the lime set being attached thereto a supplement pipe 4, lime set supplement pipe 4 is equipped with control valve 6.

It is interconnected between said elements entrance by connecting pipe.

The present apparatus is opened before 5 start-of-run of hydrogenation reactor, by the steam inlet 23 of venturi circulating pump 2 before opening High-temperature steam is connected, while opens the control valve 6 of lime set supplement pipe 4, steam and lime set enter venturi circulating pump 2, utilize text Principle in mound, high-temperature vapor are ejected into chuck 1 by mixture export 22 and vacuumized, and the air pressure of 1 lower end of chuck reduces shape Into low-pressure area, meanwhile, the lime set being supplemented into chuck 1 by lime set supplement pipe 4 in chuck 1 enters low pressure under pressure Area is mixed with vapor, and vapor liquidation exothermic reaction forms lime set, 1 surface of chuck heating, since chuck 1 is around hydrogenation reactor 5 Setting, chuck 1, which heats up, heats hydrogenation reactor 5.

At the same time, the lime set that 1 top of chuck condenses returns to venturi circulating pump 2 again by the condensate outlet 12 of chuck Vapor is mixed to form with high-temperature steam to enter in chuck 1, forms heat cycles.Since vapor and lime set are uniform by four The entrance being looped around around chuck 1 enters chuck 1, it is ensured that the temperature in chuck 1 uniformly increases.Open simultaneously 1 side of chuck The fluid guidance port 7 of face lowest point discharges extra water.

When temperature reaches 100 DEG C in chuck 1, fluid guidance port 7 is closed, the lime set boiling in chuck 1 generates vapor, water Steam is entered by the steam (vapor) outlet of 1 upper end of chuck in drum 3, and the pressure in drum 3 constantly increases, and due to pressure rise, is coagulated Liquid temperature also constantly increases, and lime set is entered by the condensate outlet 32 of drum in venturi circulating pump 2 at this time, forms high temperature again Vapor enters in chuck 1, and continuous heating is carried out to chuck 1, at this point, by controlling 3 pressure of drum and heating quantity of steam can be with The temperature of hydrogenation reactor 5 is controlled, reaches the temperature needed for reaction.After reaching required temperature, start-of-run is waited for.

In the course of work, the liquid level that can observe the lime set in chuck 1 according to the liquid level gauge 8 of 1 side of chuck at any time changes, And it opens fluid guidance port 7 at any time and discharges extra water.
