Abstract

The utility model relates to a high temperature resistance and high pressure resistance reactor convenient for loading and unloading catalysts, comprising a reactor barrel, an upper plug, a lower plug, a lower press module welded at two ends of the reactor barrel and an upper press module matched therewith, a lock nut, a thermocouple bushing, a catalyst support, an O-shaped seal ring between the upper and lower press modules and an aluminium radiation sheet between the upper and lower press modules at the inlet and outlet of the reactor. The reactor is provided with simple structure, easy sealing, convenient disassembling and low cost.

Description

A kind of reactor of high temperature resistant, high pressure loading and unloading convenient catalyst

One, technical field

The utility model belongs to the middle-size and small-size experimental rig technology of petrochemical industry, belongs to petrochemical industry scientific research equipment technology field.

Two, background technology

The middle-size and small-size experimental rig of petrochemical industry is the exploitation new technology, the important tool of evaluate catalysts, and reactor is its key equipment.Because reaction is 350 ℃～450 ℃ of high temperature, work under high pressure 15～18MPa condition, it is ring flange shimming form, all-metal emulsus seal form that its structure and sealing means mostly were two ends originally, its shortcoming is: sealing trouble during the loading and unloading catalyst, easily leak, the efficient that wastes time and energy is low, and the machining accuracy requirement is high, cost is high, directly influence scientific research efficient, strengthen cost of investment.

Three, summary of the invention

The purpose of this utility model provides a kind of reactor of high temperature resistant, high pressure loading and unloading convenient catalyst, with its rational structure characteristic and seal form solved difficult sealing, machining accuracy height that equipment in the past exists, problem such as investment is big, efficient is low.

This purpose realizes with following technical proposal: it has reactor shell, go up lower end cap, be welded on compressing lower module and its last compression module that is complementary, locking nut, Thermal couple casing pipe, catalyst carriage and be fixed on the aluminium heat sink on the reactor shell between the reactor charging and discharging mouths such as sealing " O " type ring between the upper and lower compression module with externally threaded of reactor shell two ends, and catalyst carriage and Thermal couple casing pipe are put into reactor shell.

In this reactor, the a pair of compression module up and down in two ends, add a rubber " O " type sealing ring in the middle of it, external screw thread by locking nut and following compact heap is tightened, compress compact heap, making it form straight line moves, thereby compressed " O " type ring, made its effect that reaches sealing, because " O " type is a kind of flexible material, very easy compressing reaches sealing purpose, simple in structure, again because be to rotate by nut to compress, screw sealing of ring flange back cushion sheet or metal wire sealing dismounting simply, not only convenient, and save cost.Because added the aluminium fin between reactor upper/lower terminal and feed inlet and outlet, therefore the temperature that " O " ring place is born reduces greatly, plays sealing purpose again.Satisfy high pressure, hot test requirement, improved scientific research efficient.

Following accompanying drawing has provided implementation example of the present utility model:

Four, description of drawings

Accompanying drawing is the utility model internal structure and part peripheral hardware accessory syndeton schematic diagram

Five, the specific embodiment

Now in conjunction with the accompanying drawings this reactor monolith structure and operation principle are described in detail:

As shown, the sealed at both ends mode of this reactor is identical, with the upper end is the example explanation, it has drum type brake reaction tube 1, weld respectively at the cylindrical shell two ends and to be with externally threaded confinement element 2, logical stifled 3 one ends in two ends link together with external thread form and upper end clamping element 6 usefulness engage thread, this connector is inserted in the reaction tube, one rubber " O " type ring 4 is arranged between clamping element 2 and clamping element 6, locking nut 5 is connected with element 2 and locks, element 2 and element 6 are compressed, make " O " type annular strain reach the purpose that compresses sealing, more than the material of each element except that " O " type ring, all be 316SS, element 7 is fin of aluminium material, be fixed on the cylindrical shell between the above of Reactor inlet and the upper end compact heap, its effect is to make on the reactor, the lower end temperature is reduced to about 200 ℃, to satisfy the temperature that " O " type ring is born, thermocouple sheath 8 is logical stifled through the lower end, and pass catalyst carriage 9, and be fixed on the compressing member of lower end, thermocouple inserts in the sleeve pipe and measures its reaction temperature, and the catalyst that catalyst bracing frame 9 will be packed in the reactor is held.

The course of work of this reactor: reactor upper end locking nut and briquetting and plug are dismantled, its lower end is motionless, catalyst is slowly packed into from the reaction mouth of pipe of upper end, and constantly vibration, make the catalyst filling evenly, then the upper end plug is packed into, pay special attention to Thermal couple casing pipe is inserted in the upper holder block locating hole, the locking top nut, seal, after pressure testing is qualified, unstripped gas liquid is entered the reactor from charging aperture in the test requirements document ratio, pass through beds, at certain pressure, under the temperature conditions, begin reaction, material constantly flows out from discharging opening, through the certain reaction time, reaction finishes, turn on reactor lower end nut, catalyst is drawn off, and then do second catalyst sample.

Claims

1. the reactor of high temperature resistant, a high pressure loading and unloading convenient catalyst, it has reactor shell, go up lower end cap, be welded on the reactor shell two ends with externally threaded compress lower module and its last compression module that matches, locking nut, Thermal couple casing pipe, catalyst carriage and be in sealing " O " ring between the upper and lower compression module and the reactor feed inlet and outlet about aluminium heat sink between the compression module, catalyst carriage and Thermal couple casing pipe are put into reactor shell.
