Abstract
The utility model discloses a temperature control protector of a slurry bed reactor; an upper portion and a lower portion of the slurry bed reactor are respectively provided with 16 temperature sensors; each temperature sensor is arranged inside the slurry bed reactor; a signal output end of each temperature sensor is connected with a signal input end of a DCS controller; a signal output end of the DCS controller is connected with a signal input end of a computer; a signal output end of the computer is connected with a signal input end of inlet raw material gas regulating valve of the slurry bed reactor. The advantages are that a plurality of temperature testing points for temperature measurement are arranged in the slurry bed reactor and linked for control, and catalyst temperature runaway coking risk is eliminated, thereby eliminating main reactor damaging risk caused by temperature runaway.
Description
Technical field
The utility model relates to a kind of temperature control protective device, particularly relates to a kind of temperature control protective device of paste state bed reactor.
Background technology
The former design operation temperature of paste state bed reactor is 260 ± 20 ℃, when paste state bed reactor is all raw catelyst, easily causes paste state bed reactor temperature runaway after reaching catalyst activity point, if control the bad catalyzer coking that easily causes.
At present, move heat control slurry reactor actuator temperature by drum, temperature is not hung chain, and during unexpected temperature runaway, Operating condition adjustment is crossed and can be caused slowly catalyzer coking.
Utility model content
The purpose of this utility model is to provide a kind of temperature control protective device of paste state bed reactor.
The purpose of this utility model is implemented by following technical scheme, a kind of temperature control protective device of paste state bed reactor, the upper and lower of paste state bed reactor is respectively equipped with 16 temperature sensors, each described temperature sensor is all located at the inside of described paste state bed reactor, the signal output part of each described temperature sensor is all connected with the signal input part of DCS controller, the signal output part of described DCS controller is connected with the signal input part of computing machine, the signal output part of described computing machine is connected with the signal input part of the entrance unstripped gas control valve of described paste state bed reactor.
16 points for measuring temperature are selected respectively in paste state bed reactor top and bottom, 16 points for measuring temperature are equipped with temperature sensor, 16 points for measuring temperature are distributed in respectively inside reactor, with 16 groups of points for measuring temperature, can realize more accurately and recording, prevent local temperature runaway, the actual value that any 5 groups of points for measuring temperature of paste state bed reactor top and bottom are measured reaches after setting value jointly as reporting to the police and interlocking value.Increase after temperature alarming and interlocking, any 5 groups of point for measuring temperature temperature of top and bottom reach after 278 ℃ jointly, and computing machine sends sound and light alarm.Any 5 groups of point for measuring temperature temperature of top and bottom reach after 280 ℃ jointly, and paste state bed reactor entrance unstripped gas control valve carries out interlocking close, allow paste state bed reactor stop reaction.Temperature is carried out air inlet again after falling.
The utility model has the advantage of, by multiple point for measuring temperature thermometrics chain control are set in paste state bed reactor inside, eliminated the risk of catalyzer temperature runaway coking, thereby eliminated the risk that causes main reactor to damage due to temperature runaway.
