Embodiment 1

[0054] Using Henan Yima coal as raw material, the entrained bed reactor with a single reactor daily processing capacity of 900 tons of coal has a combustion chamber shell diameter of 2800 mm, an operating pressure of 6.5 MPa, and an operating temperature of 1380 °C. In this embodiment, the temperature measurement system for the outer surface of the metal shell of the entrained bed reactor adopts figure 1 The temperature measurement system is shown. The outer surface of the entrained bed reactor is divided into 22 temperature measurement areas, of which the outer surface of the dome is divided into 6 temperature measurement areas, the outer surface of the upper section of the cylinder is divided into 8 temperature measurement areas, and the outer surface of the lower section of the cylinder is divided into 8 temperature measurement zones. In the temperature measuring area on the outer surface of the dome of the entrained bed reactor, press image 3 Install armored cable therm...

Embodiment 2

[0069] In a domestic production facility with an annual output of 160,000 tons of synthetic oil, the shell diameter of the entrained bed reactor combustion chamber is 3200 mm, the operating pressure is 4.0 MPa, and the operating temperature is 1340 °C. The outer surface temperature measurement system of the metal shell of the entrained bed reactor adopts figure 2 Shown is the outer surface temperature measurement system of the metal shell of the entrained bed reactor. In this embodiment, the outer surface of the metal casing of the entrained bed reactor combustion chamber is divided into 28 temperature measurement areas, of which the outer surface of the vault is divided into 8 temperature measurement areas, and the outer surface of the upper section of the cylinder is divided into 10 temperature measurement areas. Temperature zone, the outer surface of the lower section of the cylinder is divided into 10 temperature measurement zones. Armored thermocouples are arranged in t...

Abstract

The invention discloses a system for measuring the outer surface temperature of a metal shell of an air-flow bed reactor. The system comprises an armored cable type thermocouple, a thermocouple compensating lead, a temperature display alarm instrument and the like. The system can effectively detect and display the outer surface temperature of the metal shell of the air-flow bed reactor in real time, sends an acousto-optic alarm signal when the outer surface temperature of the metal shell is lower than the lower limit of the normal temperature range or higher than the upper limit of the normaltemperature range so as to timely prompt operating personnel to take measures, and can effectively reduce the accident occurrence probability of the air-flow bed reactor and the labor intensity of the operating personnel, improve the operation safety and the operating rate of the air-flow bed reactor and guarantee the safety of the operating personnel and a gasification device. The system has thecharacteristics of simple structure, low cost, high alarm display accuracy and high reliability and is easy to industrialize and popularize.

Description

【Technical field】 [0001] The invention belongs to the technical field of hydrocarbon material gasification. More specifically, the invention relates to a temperature measurement system for the outer surface of a metal shell of an entrained bed reactor. 【Background technique】 [0002] Hydrocarbon material gasification technology is a kind of incomplete combustion of hydrocarbon materials (coal, petroleum coke, asphalt, oil and coal liquefaction residue, etc.) to convert them into H 2 and CO clean syngas technology. Syngas can be used not only for the production of basic organic chemical products and fine chemicals, but also for the indirect liquefaction of coal, combined cycle power generation and coal-based polygeneration technology. Therefore, the gasification technology of hydrocarbon materials is the core technology for the clean and efficient conversion of hydrocarbon materials. , gas-steam combined cycle power generation, hydrogen production, fuel cells, direct reduc...
