Description

Technical Field

[0001] The invention relates to the field of gasification reactors, in particular to a multi-tubular fluidized bed gasification reactor driven by high-temperature solid particles. Background Art

[0002] As an effective means of clean coal conversion, coal gasification technology generates high value-added synthesis gas by causing coal to react chemically with water vapor or carbon dioxide under high temperature conditions. This not only improves the utilization efficiency of coal, but also significantly reduces pollutant emissions. However, the self-heating gasification of coal consumes a considerable portion of raw materials, and the introduction of the air separation system will also increase the energy consumption of the entire coal gasification system. Applying concentrated solar energy as a heat source to the coal gasification process can not only promote the clean and efficient use of coal resources, but also contribute to the development and utilization of renewable energy. Therefore, the use of solar-driven coal gasification technology has become an advanced approach with both environmental and economic benefits.

[0003] The problems of intermittent solar energy during the day and night and uneven energy flow distribution make it impossible to directly drive the coal gasification reaction to operate continuously through solar energy. Using solid particles as heat absorption and heat storage media is expected to achieve continuous operation of coal gasification driven by concentrated solar energy. Obviously, in this system, the high-temperature solid particle-driven coal gasification reactor is its core equipment, which determines the feasibility and efficiency of the system. Although the direct contact between solid particles and coal particles can increase the heat transfer rate, it will cause the particles that serve as heat absorption and heat storage media to coke, agglomerate, slag, and wear. Therefore, how to ensure the heat load in the reactor through structural design is the key to the high-temperature solid particle-driven coal gasification reactor. Summary of the invention

[0004] The object of the present invention is to provide a multi-tubular fluidized bed gasification reactor driven by high-temperature solid particles, comprising a heat-insulating interlayer, a ring multi-tubular fluidized bed gasification reactor, and a heat recovery heat exchanger.

[0005] The heat-insulating interlayer provides heat for the multi-tube fluidized bed gasification reactor.

[0006] The annular multi-tube fluidized bed gasification reactor comprises a fluidized bed gas chamber, a fluidized bed distribution plate, a feeding system, a gasification reaction furnace, a cyclone separator, and a material return device.

[0007] The fluidized bed gas chamber receives the gasifying agent and delivers the gasifying agent to the fluidized bed distribution plate.

[0008] The gasifying agent flowing through the fluidized bed distribution plate fluidizes the particles in the gasification reaction furnace and undergoes a gasification reaction with the particles to generate synthesis gas, and the synthesis gas entrained with a portion of the solid particles is sent to the cyclone separator.

[0009] The feeding system is used to feed coal particles and catalyst particles consumed in the reaction process into the gasification reaction furnace.

[0010] The gasification reaction furnace is pre-stored with inert quartz particles for heat storage and heat exchange enhancement and catalyst particles for reducing the gasification reaction temperature.

[0011] The cyclone separator separates the synthesis gas and solid particles, sends the separated synthesis gas to the heat recovery heat exchanger, and sends the separated solid particles to the return device.

[0012] The return device returns the solid particles to the fluidized bed gasification reaction furnace.

[0013] The heat recovery heat exchanger recovers the heat of the synthesis gas, heats the gasifying agent, and sends the heated gasifying agent into the circulating multi-tubular fluidized bed gasification reactor.

[0014] The heat recovery heat exchanger recovers the heat of the synthesis gas and preheats the gasification agent introduced from the outside, and then sends the preheated gas to the circulating multi-tubular fluidized bed gasification reactor.

[0015] Furthermore, the fluidized bed distribution plate includes a plurality of tubular fluidized beds distributed at intervals.

[0016] Furthermore, the inert particles added to the gasification reaction furnace enhance the heat exchange in the fluidized bed and the catalyst particles reduce the temperature required for the reaction.

[0017] Furthermore, the thermal insulation interlayer has a heat storage particle feeding pipe and a heat storage particle discharging pipe.

[0018] The heat-insulating interlayer stores high-temperature particles through a heat-storage particle feeding pipe to supply heat to the annular multi-tube fluidized bed gasification reactor.

[0019] The thermal insulation interlayer releases high temperature particles through the heat storage particle discharge pipe.

[0020] Furthermore, the gasifying agent flowing through the fluidized bed distribution plate undergoes a gasification reaction with the particles under the heating of the heat-insulating interlayer to generate synthesis gas.

[0021] Furthermore, the annular multi-tubular fluidized bed gasification reactor is provided with a fluidizing gas inlet.

[0022] The gasifying agent enters the fluidized bed chamber through the fluidizing gas inlet.

[0023] Furthermore, the heat recovery heat exchanger is provided with a hot fluid inlet and a hot fluid outlet.

[0024] The heat recovery heat exchanger receives the synthesis gas separated by the cyclone separator through the hot fluid inlet, and recovers the heat of the synthesis gas.

[0025] The cooled synthesis gas is sent out through the hot fluid outlet.

[0026] Furthermore, after the cooled synthesis gas is sent out through the hot fluid outlet, the cooled synthesis gas is processed by the Fischer-Tropsch synthesis method to convert the synthesis gas into hydrocarbon liquid fuel.

[0027] Furthermore, the cyclone separator has a gas outlet.

[0028] The gas outlet is in communication with the hot fluid inlet so as to feed the synthesis gas into the heat recovery heat exchanger.

[0029] Furthermore, the heat recovery heat exchanger is provided with a cold fluid inlet and a cold fluid outlet.

[0030] The heat recovery heat exchanger receives the gasification agent through the cold fluid inlet and heats the gasification agent using the heat of the synthesis gas.

[0031] The heat recovery heat exchanger delivers the heated gasifying agent into the circulating multi-tubular fluidized bed gasification reactor through the cold fluid outlet.

[0032] The technical effect of the present invention is undoubted, and the beneficial effects of the present invention are as follows:

[0033] 1) Allow more heat to be transferred to the gasification medium through the heat storage particles, ensuring the efficient gasification reaction.

[0034] 2) The shortened heat transfer path helps achieve a more uniform temperature distribution, reduces local overheating, and avoids damage to reactor materials and decreased gasification efficiency due to excessive temperature gradients.

[0035] 3) The inclination of the bottom of the tubular fluidized bed is conducive to the flow of heat storage particles.

[0036] 4) Using quartz particles as the bed material of the fluidized bed ensures the stability of the bed, strengthens the heat exchange with the coal powder, prevents the coal powder from agglomerating and settling, and improves the continuity and stability of the gasification reaction. The addition of catalyst particles reduces the activation energy of the gasification reaction, helps the reaction proceed at a lower temperature, and prolongs the operating life of the reactor.

[0037] 5) A heat recovery system is set up to recover the heat in the synthesis gas for preheating the gasifying agent. The increase in the temperature of the gasifying agent is more conducive to the occurrence of the gasification reaction and improves the efficiency of the reactor.

[0038] In summary, the present invention significantly increases the contact area between the reactor and the heat storage particles in the thermal insulation interlayer, thereby improving the heat exchange efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
