The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
Fig. 1 is refer to, Fig. 1 is the structural representation for the device for producing hydrogen isothermal hydrogen addition reactor that the utility model embodiment provides
Figure.
The device for producing hydrogen isothermal hydrogen addition reactor that the utility model embodiment provides, including tank body 3 and be built in tank body 3
Upper perforated plate, lower perforated plate 4 and tubulation 1, upper perforated plate is arranged on the top of tubulation 1, and lower perforated plate 4 is arranged on the lower section of tubulation 1, upper tube
The top of plate is provided with ceramic support 2, and ceramic support 2, the top of lower perforated plate 4 are placed with the body on the top of tubulation 1
Ceramic support 2 is provided with, ceramic support 2 is placed with the body of the end of tubulation 1.Hydrogen manufacturing dress provided by the utility model
Put isothermal hydrogen addition reactor to cancel the upper catalyst agent for being located at upper perforated plate in the prior art, change ceramic support 2 into, will be existing
Catalyst in technology in the body on the top of tubulation 1 is cancelled and changes ceramic support 2 into, under being located in the prior art
The upper catalyst agent of tube sheet 4 is cancelled, and changes ceramic support 2 into, by urging in the body for the end for being located at tubulation 1 in the prior art
Agent is cancelled and changes ceramic support 2 into.The place easily ftractureed is avoided because the temperature difference caused by the presence of catalyst is big, is led to
The optimization of reactor catalyst filling is crossed, reduces the temperature difference of weak spot at reactor two, equipment long-term operation is ensured, avoids letting out
Leakage.
In the prior art, inside reactor material is 15CrMoR, and the temperature difference becomes at reactor internal tube plate in practical operation
Change it is larger, because temperature differencies crack (temperature is identical with vapor (steam) temperature at tube sheet, at 240 DEG C, tube sheet bottom and upper catalyst
280 DEG C of agent, when olefin(e) centent is high, more than 300 DEG C can be reached)；Also, the position for finding to have crackle through internal check is located at
Two planes at the top and bottom of tube side, it is not once to complete in welding because material is special when equipment is dispatched from the factory, the temperature of heat treatment
Degree may change, therefore it is vulnerable area to analyze this at two.
The utility model is the change using catalyst in reactor type of feed, reduces the reaction heat at tube sheet, so as to
Temperature difference in reduction at lower perforated plate 4, ensure that the change of equipment thermal expansion coefficients is reduced, protect tube sheet not ftracture, so as to reach
The purpose of long-term operation.
Wherein, ceramic support 2 is porcelain ball.
Wherein, for the ceramic support 2 placed in the body on the top of tubulation 1 down to be set from the end face on top, it is thick
Degree avoids that heat can not transmit or transmission effect is poor more than the thickness of upper perforated plate.Similarly, put in the body of the end of tubulation 1
For the ceramic support 2 put up to be set from the end face of end, its thickness is more than the thickness of lower perforated plate 4.
Wherein, the thickness of upper perforated plate is 5cm, and the thickness for the ceramic support 2 placed in the body on the top of tubulation 1 is
10cm.The thickness of lower perforated plate 4 is 5cm, and the thickness for the ceramic support 2 placed in the body on the top of tubulation 1 is 10cm.That
, total 7.8 tons of the catalyst of dress of isothermal reactor tubulation of the prior art and reactor top and the bottom, by tube sheet upper catalyst agent
Cancellation changes porcelain ball into, and top tubulation internal upper part 10cm changes porcelain ball into.Lower catalytic agent, which is cancelled, changes porcelain ball into, in the 10cm of tubulation bottom
Catalyst is not filled and changes porcelain ball into, adds up to last 5 tons of Catalyst packing.
Wherein, the ceramics placed in the ceramic support 2 and the body of the end of tubulation 1 that the top of lower perforated plate 4 is set
Supporter 2 is porcelain ball and its a diameter of 13mm.The ceramic support 2 and the pipe on the top of tubulation 1 that the top of upper perforated plate is set
The ceramic support 2 placed in vivo is porcelain ball and its a diameter of 6mm.Catalyst bottom is by the use of the porcelain balls of φ 13 as support, to prevent
Tubulation 1 is blocked in the accumulation of porcelain ball in tube bank, when top is loaded, the porcelain balls of φ 6 is loaded in tubulation 1, facilitate maintenance to unload agent.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
