Abstract

The utility model relates to a gas recovery apparatus, particularly a tail gas reclaimator of a slip activating furnace. The utility model solves the problem that the activating tail gas generated by the slip activating furnace can not be reused in the existing production of an activated carbon process in the prior art. The utility model comprises a pipeline, and the side wall of one end of the pipeline is provided with a tail gas inlet pipe. A steam air inlet pipe is sheathed at the same end, and the pipe wall of the inside of the steam air inlet pipe is embedded with a conical pipe, both ends of which are extended in cone shapes. The utility model has the advantages of convenient installation, no shutdown, simple operation, no maintenance, no power consumption and no rapidly worn component. The activating tail gas (comprising a great deal of steam and carbon dioxide) is sucked in the furnace again by the bottom of a heat storage chamber. A large amount of steam is economized, and the flow velocity and concentration of the activating gas in the furnace are also increased. The productivity is raised, the exhaust emission is reduced, and the temperature of the activating tail gas is high, so that the steam in the furnace is sufficiently pre-heated. Thus, the burning loss of a carbonization material is further reduced and the product yield is enhanced.

Description

Slapple activating furnace tail gas recycle device

Technical field

The utility model relates to a kind of gas concentration unit, specifically is a kind of Slapple activating furnace tail gas recycle device.

Background technology

Activation procedure is the operation of most critical in the Activated Carbon Production process, it directly has influence on performance, cost and the quality of activated carbon product, the main Slapple activating furnace that adopts activates in the existing technology, this be a kind of be the type of furnace of activator with water vapor and stack gas, in China's gac manufacturing, obtained widely using.Activation tail gas (containing a large amount of steam and carbonic acid gas) is but often drained, and has caused the waste of the energy and water resources yet in actual applications.

Summary of the invention

The problem that the utility model can't utilize for the activation tail gas that solves Slapple activating furnace generation in the production activated carbon process that exists in the prior art again, and a kind of novel Slapple activating furnace tail gas recycle device is provided.

The utility model is achieved by the following technical solution: a kind of Slapple activating furnace tail gas recycle device comprises pipeline, be connected to the tail gas inlet pipe on the sidewall of pipeline one end, in its same termination sealing cover is arranged, and pass sealing cover and be socketed with steam inlet duct, the steam inlet duct inner pipe wall is embedded with the two ends expansion and is tapered Taper Pipe.

In actual applications, the tail gas discharge manifold of tail gas import and Slapple activating furnace joins, steam inlet duct feeds high pressure steam, be accelerated behind the Taper Pipe of high pressure steam by steam inlet duct inside, high velocity vapor forms negative pressure in the withdrawer internal space after passing Taper Pipe, and the tail gas that helps the Slapple activating furnace generation is fully drawn.Mixed gas is introduced in the Slapple activating furnace again and is continued to react as activated gas through the outlet ejection subsequently.

Slapple activating furnace tail gas recycle device described in the utility model, simple installation need not blowing out, and is simple to operate, need not safeguard non-power consumption, no easily worn part.Utilize the venturi principle, the parital vacuum that energy of flow by high pressure steam produces, to activate tail gas (containing a large amount of steam and carbonic acid gas) and suck again in the stove, not only save steam in a large number, and can increase the flow velocity and the concentration of activated gas in the stove by regenerator bottom, Gu making gas-speed of response accelerates, increase output, reduce exhaust emissions, because the higher steam in the boiler that also can make of activation exhaust temperature obtains abundant preheating, further reduce carbonized material and burn mistake, improve the product yield.
