Steam injection system in high-temperature converter

Abstract

The invention discloses a steam injection system in a high-temperature converter. The high-temperature converter comprises a furnace body, a plurality of steam pipes are arranged in the furnace body in the axial direction, a first steam inlet and a second steam inlet are formed in the two ends of each steam pipe correspondingly, and a steam storage tank is arranged outside the furnace body. A first steam inlet in one end of each steam pipe is communicated with a steam outlet in the top of the steam storage tank through a connecting pipe. A plurality of steam spraying holes are formed in the bottom of each steam pipe, the outer side of each steam pipe is sleeved with an outer sleeve, and an interlayer structure is formed between the outer side wall of each steam pipe and the inner side wallof the corresponding outer sleeve. A hot water inlet is formed in the outer side wall of one end of each outer sleeve, a hot water outlet is formed in the outer side wall of the other end of each outer sleeve, the hot water inlets are communicated with the lower portion of the steam storage tank through connecting pipes, and the hot water outlets are communicated with the upper portion of the steam storage tank. The structure is simple, the steam pipes can normally work in the high-temperature converter, the production efficiency is high, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of activated carbon processing and production equipment, in particular to a steam injection system in a high-temperature converter. Background technique [0002] Activated carbon is a kind of adsorption material with well-developed pore structure, large specific surface area, non-toxic and odorless, and has a strong ability to adsorb molecules. It has been widely used as an adsorbent and decolorizing agent in many fields such as medicine, chemical industry, food, environmental protection, and metallurgy. . [0003] At present, in the production and preparation of activated carbon, it is necessary to use a high-temperature converter to activate the carbonized material. In the prior art, the steam injection system in the high temperature converter is as figure 1 As shown, it is mainly composed of a steam injection pipe 2' arranged in the furnace body 1'. One end of the steam injection pipe 2' is provided wit...

Problems solved by technology

However, the existing steam injection system in this high-temperature converter has the following defects: (1) Since the steam injection pipe is directly arranged in the high-temperature converter body, it is in direct contact with the high-temperature carbonized material, and long-term use will cause the surface of the steam injection pipe to oxidize and block the injection pipe. The steam hole will shorten the service life of the steam injection pipe, and the steam injection pipe needs to be made of high-temperature resistant materials, and the overall cost is high; (2) If the pressure in the boiler steam st
