Problems solved by technology

[0007] In summary, the chilled reactor has the advantages of simple equipment, convenient operation, and high operating efficiency of the device, but the energy utilization efficiency needs to be improved
Compared with the chilled reactor, the energy utilization efficiency of the all-waste pot reactor is high, but the equipment structure is complex, the investment cost is high, the reactor is prone to slagging and ash accumulation, the operation efficiency of the device is not high, and the labor intensity of reactor maintenance is high, etc. The problem, these two reactors have their own characteristics, and their applicable areas are different

Embodiment 1

[0081] Embodiment 1: Chilling type single waste pot reactor of the present invention

[0082] The quenching type single waste pot reactor of the present invention is composed of an upper gasification reaction chamber 4, a middle radiation heat exchange chamber 13 and a lower quenching slag chamber 18. The gasification reaction chamber 4 passes through a conical slag opening 5 and a conical The gas guide port 12 communicates with the radiation heat exchange chamber 13 , and the radiation heat exchange chamber 13 communicates with the chilled slag chamber 18 through a funnel-shaped slag collector 23 and an air guide pipe 21 .

[0083] The wall of the gasification reaction chamber 4 is composed of a reactor shell 1 made of SA387Gr11CL2 material and a refractory material layer 2 fixed on the inner wall of the reactor shell 1 .

[0084] The refractory material layer 2 is a fire-facing refractory brick sold by Henan Burma Co., Ltd. under the trade name high chrome brick LIRR-HK90, a...

Abstract

The invention relates to a chilling type single waste pan reactor. The reactor consists of an upper gasification reaction chamber, a middle radiation heat exchange chamber and a lower chilling slag chamber, wherein the gasification reaction chamber is communicated with the radiation heat exchange chamber by virtue of a conical slag opening and a conical gas guide inlet; and the radiation heat exchange chamber is communicated with the chilling slag chamber by virtue of a funnel-shaped slag trap. At present, a chilling type reactor in the conventional industrial reactor is low in energy utilization efficiency, the efficiency needs to be improved, and the all waste pan reactor is complex in structure, high in investment cost, low in operating stability, low in raw gas vaporization ratio and large in ash content and is unsuitable to serve as chemical synthesis gas. Moreover, the chilling type single waste pan reactor disclosed by the invention simultaneously has the advantages of a waste pan reactor and a chilling reactor, the energy utilization efficiency of the reactor is improved by 4-5 percent compared with the chilling reactor, the ash content is reduced by 2mg / L compared with the all waste pan reactor, and the vaporization ratio is improved to 0.8 to 1.0. The reactor disclosed by the invention is suitable for IGCC power generation and combined generation chemical synthesis.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of energy chemical industry. More specifically, the present invention relates to a chilled single waste pot reactor. [0003] 【Background technique】 [0004] Entrained bed coal gasification technology is currently the main synthesis gas production technology. The industrial scale entrained bed reactor generally operates at a temperature of 1200-1500°C, and its gasification products are characterized by high temperature and carry a large amount of sensible heat. Bed coal gasification reactors can be divided into chilled reactors and full waste boiler reactors according to the crude gas cooling methods. [0005] The chilled reactor has a simple equipment structure and is easy to operate. The chilled reactor is used to produce crude gas. The crude gas discharged from the chilled reactor has a low dust content and a high steam ratio, which can reach 1.3 to 1.42. It can be directly sent to the follow-up...
