Description

High-efficiency energy-saving horizontal rotation activation furnace

Technical field

The present invention relates to a kind of activation furnace, particularly relate to a kind of high-efficiency energy-saving horizontal rotation activation furnace.

Background technology

Gac has very flourishing internal pore structure and bigger specific surface area as sorbent material, is mainly used in fields such as chemical industry, food, medicine, military affairs and environment protection.In the equipment of producing gac, activation furnace is one of very crucial equipment, and the activation furnace that people use is generally horizontal rotation activation furnace.Carbonized material or spent sorbents need the regular hour to be able to activation under the environment of activation furnace high-temperature and water vapor; But the method for people's employing is at present normally got into the activation storehouse of activation furnace through the discharge end of activation furnace by special boiler for producing water vapor; To reach 800 ℃ high temperature than the material of discharge end much lower because of the temperature of water vapor, thereby this has reduced the activation that material temperature influences material on certain degree; Again because part carbonized material or spent sorbents and water vapor at high temperature generate carbon monoxide and hydrogen; Have plenty of directly and discharge then polluted air to the external world; Have plenty of in activation furnace the certain air of input and make carbon monoxide and hydrogen and oxygen reaction produce heat guaranteeing temperature in the activation furnace, but oxygen also generates carbonic acid gas and has the phenomenon of wasting material with carbonized material or spent sorbents reaction simultaneously in the air; The gas temperature that is produced behind the material activating in the activation storehouse of activation furnace is very high, but this part heat energy is directly to discharge through vapor pipe to be wasted; Material in the activation furnace activation storehouse of people's use at present is to rotate along with the rotation of body of heater basically in addition; Though the device that the flight class is installed is also arranged in the activation storehouse that has; This type flight structure design is also unreasonable; Causing material is very inadequate with contacting of high-temperature water vapor in activation furnace; Mainly be because the number of times that has a lot of materials in the activation storehouse, to be stirred is few, in the body of heater rotating process, also exist many materials to be accumulated in the bottom in activation storehouse, thereby it be very undesirable to make that material and high-temperature water vapor can not contact the effect that causes material activating cmpletely.

Summary of the invention

The objective of the invention is in order to overcome deficiency of the prior art the high-efficiency energy-saving horizontal rotation activation furnace that a kind of activation efficiency height, environmental protection is provided and cuts down the consumption of energy greatly.

For realizing above-mentioned purpose; The present invention provides a kind of high-efficiency energy-saving horizontal rotation activation furnace, comprises body of heater, activation storehouse and chimney, and said high-efficiency energy-saving horizontal rotation activation furnace is provided with steam-generating installation, internal combustion chamber and vapor pipe; Said steam-generating installation is provided with water tank; The upper end of water tank is provided with water inlet pipe and pneumatic tube, is provided with prolong in the water tank, and the upper and lower end of said prolong is communicated with chimney, vapor pipe respectively; Said pneumatic tube is communicated with the feed end in activation furnace activation storehouse; The discharge end in activation furnace activation storehouse is provided with inlet pipe and gets into internal combustion chamber, and internal combustion chamber is communicated with vapor pipe at the activation furnace feed end; Be provided with a plurality of parallel with body of heater and isometric T-shaped flights on said activation storehouse furnace body inside outer wall and the internal combustion chamber outer wall with internal combustion chamber; Said flight is provided with copies post and baffle plate; An end and activation storehouse furnace body inside outer wall or the internal combustion chamber outer wall of destroying post radially weld, and the other end of destroying post vertically welds in the middle part of baffle plate.

Be provided with on said activation storehouse furnace body inside outer wall and the internal combustion chamber outer wall T-shaped flight all be no less than 8.

Beneficial effect of the present invention is: the water vapor that high-efficiency energy-saving horizontal of the present invention rotation activation furnace at first lets steam-generating installation produce gets into the activation storehouse simultaneously with material to be activated, makes to go out the activation storehouse simultaneously after while preheating of water vapor and material and the activation and improve material activating efficient; Carbon monoxide that material and water vapor produce under hot environment in the activation storehouse and hydrogen under the internal combustion chamber suction function and after getting into internal combustion chamber with produce great amount of heat by the airborne oxygen combustion of inlet pipe input, guaranteed the needed high temperature of material activating; On the other hand, the high-temp waste gas such as carbonic acid gas that internal combustion chamber produced get into steam-generating installation through vapor pipe under action of negative pressure prolong makes the needed water vapor in activation storehouse that received thermogenesis of the water in the water tank, has practiced thrift the energy; This device make the material in the activation storehouse avoided with air in oxygen contact and oxidizedly fall, improved the yield that activation furnace is produced gac; Because of flight destroy post and baffle plate is welded as the T-shaped shape, so rotate under the situation in a week along with body of heater, material can upset in the activation storehouse repeatedly, realize the thorough mixing of material and water vapor, improved the efficient of material activating; Use the gac yield of high-efficiency energy-saving horizontal rotation activation furnace of the present invention to improve more than 20%, energy consumption is 1/12nd of a common activation furnace.

Below in conjunction with accompanying drawing high-efficiency energy-saving horizontal rotation activation furnace of the present invention is described further.
