Active carbon horizontal converter

Abstract

The invention discloses an active carbon horizontal converter in the field of equipment producing active carbon, which comprises a driving mechanism (13), a feed mechanism (12), an outer barrel (4), a gas distributing pipe (1), an exhaust pipe (24), a flue (6), a steam generator (5), and a steam pipe (7), wherein an inner barrel (27) is arranged in the outer barrel (4) and is welded in the outer barrel (4) through a vertical plate (25);at least three independent material channels (18) are formed by the separation of the vertical plate (25) between the outer barrel (4) and the inner barrel (27) ; a shoveling plate is welded in each material channel; and one end of the gas distributing pipe (1) is provided with a gas distributing pipe cover (31), while the other end extends into the inner barrel (27). The active carbon horizontal converter not only can continuously produce the active carbon with a particle size range between 60 meshes and 12 millimeters, but also ensures the bidirectional heating of the inside and outside of materials, thereby having high utilization rate of heat energy and good activation effect, and only needing the activation time for 4 to 5 hours.

Description

Technical field [0001] The invention relates to a device for producing active carbon, in particular to an active carbon horizontal converter. Background technique [0002] Activated carbon is an important material for environmental protection. It is widely used as an adsorbent and decolorizer in the fields of food, medicine, and chemical industry. It is mainly used for the treatment of industrial wastewater, urban sewage, and flue gas of thermal power generation. [0003] The commonly used equipment for producing activated carbon in our country is "Sleep furnace" and "rotary furnace", both of which have certain shortcomings. "Sleep furnace" is an internal heating static activation furnace. During the production process, the material is moved forward by its own gravity. Because the fine particle material itself is light in weight and moves slowly, it is prone to material blockage; the large particle material will be blocked due to Insufficient activation occurs in static hea...

Problems solved by technology

Analyzing the patent documents, it can be seen that this patent is an external heating furnace. Since the inner tube used as the material channel is fixed in the drum parallel to each other by steel plates with holes, even if the inner tube and the drum, and the inner tube and the inner tube are mutually The contact arrangement is also only line contact; at the same time, the volatile gas produced by the activation of the material is not burned in the drum, but is discharged to the outside through the exhaust pipe to heat the steam generator, so the material in the inner tube is only in line contact when heated The conduction heat at the place and the radiant heat close to the heat source surface lead to low utilization rate of heat energy and high energy consumption of the patent. The heating of the material is relatively uneven and the activation time is still long.
