Embodiment Construction

[0019] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0020] figure 1 It is a schematic diagram of a three-stage composite dry-wet method combustible carbon substance gasification device provided by the present invention. The three-stage composite dry-wet method combustible carbon substance gasification device consists of a reaction section 2, a quenching section 7 and The separation section 10 is connected sequentially from top to bottom.

[0021] The reaction section 2 includes a shell 1 and a vertical tube type protective wall 3 installed inside the shell 1. The vertical tube type protective wall 3 is a protective wall formed along the inner wall of the shell 1 and surrounded by finned tubes 3-1 in a cylindrical shape, and is easy to assemble. Right, welded, easy to install, short fluid path, small resistance; a temperature measuring device 3-2 is installed between the finned tub...

Abstract

The invention provides a combustible carbon material gasifying device employing a three-section composite dry and wet method. The device is characterized by comprising a reaction section, a quench section and a separating section connected from top to bottom in sequence. The reaction section comprises a casing and a vertical type protection wall arranged in the casing; an upper end and a lower end of the vertical type protection wall are respectively connected to an upper header and a lower header; and an upper slag outlet is arranged below the lower header. An inner wall of the quench section is provided with a refractory material; a chilling device capable of spraying cold air or water is arranged inside the quench section; a solid slag opening is arranged at the lower end of the quench section and connected with a baffle plate in the separation section. The separation section bottom is provided with a water bath; a solid slag outlet is arranged below the separation section; and the upper side part of the separation section is provided with a material outlet. According to the invention, the device is simultaneously applicable to a dry dedusting and wet dedusting by the chilling device capable of spraying cold air or water can be sprayed into the cold gas or water chiller; the cylindrical protection wall with fins realizes small fluid resistance and low oxygen consumption, has compact structure, and is easy for installation. The device has characteristics of low cost, high efficiency, safety and reliability.

Description

technical field [0001] The invention relates to a three-stage composite dry-wet method combustible carbon substance gasification device, which is used for clean gasification of combustible carbon substances such as coal and coke, and belongs to the technical field of combustible carbon substance gasification. Background technique [0002] The existing gasification technologies for combustible carbon materials such as coal and coke can be divided into three types according to the type of reaction bed: fixed bed, fluidized bed and entrained bed. [0003] The raw material used in the fixed bed is anthracite lump coal, briquette or coke, and the source of raw material is limited and the price is high. On the other hand, the atmospheric pressure gasification bed of the fixed bed has low temperature and low efficiency, which seriously pollutes the environment. The country has clearly stipulated that the fixed bed belongs to the outdated gasification technology to be eliminated. ...
