Embodiment 1

[0179] Using Henan Yima coal as raw material, the single-mixing atomizer coal-water slurry entrained bed reactor with a single reactor daily processing capacity of 1065 tons has a furnace shell diameter of 2.8 meters, and the operating pressure of the entrained bed reactor is 6.5 MPa , The operating temperature of the furnace is 1350°C. The cooling protection system of the mixed atomizer of the entrained bed reactor adopts figure 1 protection system shown. exist figure 1 In the middle, the pressure is normal pressure, and the cooling water in the cooling water tank 105 with a temperature of about 50°C is pressurized to 1.6MPa by the cooling water pump 306 or 307, and then enters the cooling water heat exchanger 311, where it is heated with circulating water. After heat exchange, it cools down to about 40°C and enters the cooling water coil 516 of the mixing atomizer. The cooling water with a pressure of 0.2 MPa and a temperature of about 50° C. coming out of the cooling wat...

Embodiment 2

[0210] In a domestic production plant with an annual output of 300,000 tons of synthetic ammonia and 200,000 tons of methanol, the diameter of the furnace shell of a single mixing atomizer coal-water slurry entrained bed reactor with a daily processing capacity of 78,701 tons of coal is 3.2 m, the operating pressure of the entrained bed reactor is 6.5MPa, the operating temperature of the furnace is 1320°C, and the cooling protection system of the entrained bed reactor mixing atomizer adopts figure 1 protection system shown.

[0211] In this embodiment, the cooling protection system of the mixed atomizer of the entrained bed reactor adopts the cooling protection system of the mixed atomizer of the present invention, and the hydrogen content in the outlet gas of the cooling water gas-liquid separator is measured by a hydrogen analyzer. When the hydrogen content in the outlet gas of the cooling water gas-liquid separator 401 exceeds 25ppm, the hydrogen indicating alarm device sen...

Abstract

The invention discloses a mixed atomizer cooling protection system for an entrained-flow reactor. The cooling protection system comprises twelve subsystems such as a cooling water pump self-starting subsystem, a cooling water batch liquid level control subsystem, a cooling water header pressure indicating and alarming subsystem, an emergency cooling water bath protection subsystem, a mixed atomizer cooling water inlet flow protection subsystem, a mixed atomizer cooling water outlet flow indicating and alarming subsystem, a mixed atomizer cooling water outlet temperature indicating and alarming subsystem, etc. The mixed atomizer cooling protection system can effectively protect equipment of the mixed atomizer and the mixed atomizer cooling protection system, prolong the total service life of the mixed atomizer, improve the on-stream availability of the entrained-flow reactor, and ensure the safety of personnel and equipment.

Description

【Technical field】 [0001] The invention relates to the technical field of gasification of hydrocarbon materials. More specifically, the present invention relates to a cooling protection system for a mixing atomizer of an entrained bed reactor. 【Background technique】 [0002] Hydrocarbon material gasification technology is a kind of incomplete combustion of hydrocarbon materials (including coal / petroleum coke / pitch / oil / coal liquefaction residue) 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 reduction ironmaking...
