Problems solved by technology

The flue gas in the combustion chamber and the carbonized material are in contact with the same space, and the carbonized material advances spirally along the inner wall of the furnace. This structure has a long carbonization cycle during the production process, is difficult to control, and the carbonization is uneven, too much carbonization and the product surface is not smooth. At the same time, the existing carbonization furnace directly discharges the flue gas, the energy is not recycled and it also causes environmental pollution

Embodiment Construction

[0019] Such as figure 1 , figure 2 , image 3 , Figure 4 as shown,

[0020] The main body of the present invention is an oblique horizontal rotary furnace body (1). The high-end side of the furnace body is equipped with a feed hopper (10) and a flue gas secondary utilization device, and the low-end side has a discharge port (14) and a combustion chamber. chamber (2), the furnace body has tube bundles (9) distributed circularly along the cross-section. During carbonization, the carbonized material enters the feed port distributor (11) from the feed hopper (10), goes through the tube pass, and passes through the discharge port (14 ) is discharged, the heated flue gas goes to the shell side, the carbonized material and the flue gas pass through the tube bundle separately, and the flue gas enters the incinerator (6) in the flue gas secondary utilization device through the flue (5) for secondary combustion, and the remaining heat can be It is used to heat the waste heat boile...

Abstract

The invention relates to a multi-tube external-heat fume reverse extraction rotary carbide furnace which is provided with an obliquely horizontal type rotary furnace body (1); the high end side of the furnace body is provided with a feed hopper; the lower end side of the furnace body is provided with a discharge hole (14) and a combustion chamber (2); tube bundles (9) which are annularly distributed along a cross section are arranged in the furnace body; carbonized materials and fume channels are isolated, wherein the tube pass is used for the carbonized materials and the shell pass is used for fume. The invention adopts a tubular carbonizing process, which separates heat generated by the carbonized materials and fuels and avoids the problem of excessive carbonization; moreover, the problem that coal tar in a volatile matter is stuck to the surfaces of the carbonized materials again to influence the appearance of the product and activating effect when the fume is reversely sucked back.

Description

Technical field: [0001] The invention relates to a device in the production of activated carbon, in particular to a multi-tube external heating type flue gas back extraction rotary carbonization furnace. Background technique: [0002] The carbonization furnace is a commonly used equipment in the production of activated carbon. It is a kind of equipment that pyrolyzes the carbonization raw material to form multiple holes under the condition of hypoxia and high temperature. The existing carbonization furnace usually includes an oblique rotary furnace body, a combustion chamber, The flue and the furnace body are provided with a material inlet and a material outlet. The flue gas in the combustion chamber and the carbonized material are in contact with the same space, and the carbonized material advances spirally along the inner wall of the furnace. This structure has a long carbonization cycle during the production process, is difficult to control, and the carbonization is uneve...
