Description

The high-efficiency energy-saving horizontal rotation activating oven

Technical field

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

Background technology

Gac has very flourishing internal pore structure and larger specific surface area as sorbent material, is mainly used in the 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 rotary activation furnace.Carbonized material or spent sorbents need the regular hour to be activated under the environment of activation furnace high-temperature and water vapor, but the method for at present people's employing is normally entered the activation storehouse of activation furnace by 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 temperature that has reduced material in certain degree affects the activation of material; Again because part carbonized material or spent sorbents and water vapor at high temperature generate carbon monoxide and hydrogen, have plenty of and directly discharge then polluted air to the external world, have plenty of in activation furnace and input certain air so that carbon monoxide and hydrogen and oxygen reaction produce heat with temperature in the assurance activation furnace, but oxygen also reacts the generation carbonic acid gas and has the phenomenon of wasting material with carbonized material or spent sorbents simultaneously in the air; The gas temperature that produces behind the material activating in the activation storehouse of activation furnace is very high, but this part heat energy is directly to discharge by vapor pipe to be wasted; Material in the activation furnace activation storehouse of at present people's use is to rotate along with the rotation of body of heater basically in addition, although the device that the flight class is installed is also arranged in the activation storehouse that has, this class 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 to be stirred in the activation storehouse is few, in the process that body of heater rotates, also exist many materials to be accumulated in the bottom in activation storehouse, thereby so that material and high-temperature water vapor can not to contact cmpletely the effect that causes material activating very undesirable.

Summary of the invention

The objective of the invention is in order to overcome deficiency of the prior art, provide that a kind of activation efficiency is high, environmental protection and greatly reduce the high-efficiency energy-saving horizontal rotation activating oven of energy consumption.

For achieving the above object, the invention provides a kind of high-efficiency energy-saving horizontal rotation activating oven, comprise body of heater, activation storehouse and chimney, described high-efficiency energy-saving horizontal rotation activating oven is provided with steam-generating installation, internal combustion chamber and vapor pipe, described 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 described prolong is communicated with chimney, vapor pipe respectively; Described 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 enters 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 with internal combustion chamber T-shaped flights on described activation storehouse furnace body inside outer wall and the internal combustion chamber outer wall, described flight is provided with copies post and baffle plate, an end of destroying post radially welds with activation storehouse furnace body inside outer wall or internal combustion chamber outer wall, copies the other end of post in the middle part of baffle plate vertical welding.

Arrange on described 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: high-efficiency energy-saving horizontal rotation activating oven of the present invention at first allows the water vapor of steam-generating installation generation and material to be activated enter simultaneously the activation storehouse, improves material activating efficient so that go out to activate the storehouse simultaneously after the simultaneously preheating of water vapor and material and the activation; Material and water vapor produce a large amount of heats at the carbon monoxide that produces under the hot environment and hydrogen under the internal combustion chamber suction function and after entering internal combustion chamber with by the airborne oxygen combustion of inlet pipe input in the activation storehouse, have guaranteed the needed high temperature of material activating; On the other hand, the high temperature waste gas such as the carbonic acid gas that internal combustion chamber produces under the effect of negative pressure by vapor pipe enter steam-generating installation prolong and so that the water in the water tank the has been subjected to thermogenesis needed water vapor in activation storehouse has been saved the energy; This device is oxidized so that the material of activation in the storehouse avoided contacting with oxygen in the air to be fallen, and has improved the yield of activation furnace production gac; Because of flight destroy post and baffle plate is welded as the T-shaped shape, so rotate along with body of heater in the situation in a week, material can upset in the activation storehouse repeatedly, realize fully mixing of material and water vapor, improved the efficient of material activating; Use the gac yield of high-efficiency energy-saving horizontal rotation activating oven of the present invention to improve more than 20%, energy consumption is 1/12nd of common activation furnace.

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