Embodiment

The reactor shell 25 that comprises that the glass filament reinforced plastics material is made as shown in Figure 1; Top at said reactor shell 25 seals through sealing cover 5, and the upper and lower shape of this reactor shell 25 is respectively positive trumpet type enlarging and the enlarging of falling the trumpet type, and last trumpet type is that liquid level is with the upper part; Be acid gas, water vapor and hydrogen collection district that reaction produced; Space enlargement has played shock absorption to the reaction gas that the peak produced, and realizes the stable state discharging of gas; Following trumpet type is the reactor bottom zone; The bottom is evenly distributed with eight acid resisting bricks 21; Have bigger space between adjacent two acid resisting bricks, by the glass filament reinforced plastics material make reactor inner container 23 with regard to frame on

acid resisting brick

21,25 belt caps 24 with the glass filament reinforced plastics material of reactor inner container 23 and reactor shell are sealed; The space of reactor shell 25 bottom trumpet types is the solution district; This space is bigger, helps mixing at this through acid resisting brick 21 spaces through the solution of reactor drum nickel bed 22 reactions, and nickel shot adds the nickel mouth of pipe 2 by reactor shell 25 tops and adds; In reactor inner container 23, form nickel bed 22; And keep this nickel bed 22 height, then by first of reactor shell 25 tops add solution mouth 3 add drop arranged in hot water or dilute solution to the upflow tube visor 10 till, this solution that overflows enters in the upflow tube visor 10 via riser 6.

When carrying out solution circulated, begin to feed steam to the steam-in 16 of graphite heat exchanger 17, steam condensate relief outlet 18 is discharged; Because graphite heat exchanger 17 upper and lower ends produce the temperature difference, cause the solution in the interchanger to form thermal siphon, solution is flowed out by the spout 7 of reactor shell 25 middle and upper parts; Get into solution mixing tank 11, flowed into the inlet 19 of graphite heat exchanger 17 bottoms again by outlet 12, the heating back is flowed out by interchanger top exit 15; Bottom inlet 13 by reactor drum gets in the reactor shell 25; Through nickel bed 22, get into mixing tank 11 once more then, set up the internal recycle of reactor drum thus.

When solution temperature is raised to set(ting)value in the question response device; Beginning adds the acid of certain flow at the acid-adding port 8 on mixing tank 11 tops; Add the dilute solution that solution mouth 9 adds certain flow second, through nickel bed 22 and nickel reactant, obtain the rich solution of low acidity, high nickel concentration after added acid and dilute solution are heated by graphite heat exchanger 17; Pipe by the rich solution riser above the reactor drum overflows, the amount balance of the spillage of rich solution and the dilute solution of adding and acid.In this process, the flow of acid and dilute solution, temperature, steam flow etc. can realize automatic control.

Simultaneously, in reaction process, constantly there are acid gas, water vapor and hydrogen to produce; These gases accumulate to the liquid level top, are discharged by the normal exhaust mouth 1 of reactor shell 25 tops, if the gas vol that is produced is big; When pressure is high, can be by emergent venting port 4 one discharge; Thief hole 20 sampling analysis acidity on the solution circulated pipe can be adjusted in view of the above and add sour flow.Simultaneously, offering bottom drain 14 at the bottommost of reactor bottom 25 1 sides, is the drain of solution when being used for reactor drum breakdown maintenance or stopping production.
