An adjustable ram is installed between the main combustion chamber and the auxiliary combustion chamber, the evaporator network pipe is installed inside the auxiliary combustion chamber, the heat exchanger is installed in the flue at the bottom of the heat storage tank of the activation furnace, and the frequency conversion constant pressure pump is installed In the soft water supply pipe between the tank and the evaporator network pipe of the auxiliary combustion chamber, the adjustable air supply pipe is installed at the bottom of the auxiliary combustion chamber. The amount of air required for gas combustion to fully burn the combustible gas, heat the evaporator, and generate steam.

Description

technical field [0001] The invention relates to the technical field of activator preparation in the production process of activated carbon, in particular to a saddle-type activation furnace steam self-supply device. Background technique [0002] The main activator in the production process of activated carbon is high-temperature steam. Boilers must be used to generate steam, and the use of boilers will generate fuel and power consumption. Now many activated carbon manufacturers have a variety of sources of steam, and some activated carbon manufacturers borrow other For the excess steam generated in the production site, some activated carbon manufacturers use an independent steam boiler to provide the necessary steam for the activation furnace. The above two steam sources have some disadvantages. On the one hand, the production of steam and the steam consumption of the activation furnace are not easy to synchronize and coordinate , the flow and pressure of steam are unstable,...

[0002] The main activator in the production process of activated carbon is high-temperature steam. Boilers must be used to generate steam, and the use of boilers will generate fuel and power consumption. Now many activated carbon manufacturers have a variety of sources of steam, and some activated carbon manufacturers borrow other For the excess steam generated in the production site, some activated carbon manufacturers use an independent steam boiler to provide the necessary steam for the activation furnace. The above two steam sources have some disadvantages. On the one hand, the production of steam and the steam consumption of the activation furnace are not easy to synchronize and coordinate , the flow and pressure of steam are unstable, resulting in unstable quality of activated carbon products. On the other hand, the use of independent steam boilers consumes a lot of energy such as electricity and fuel and brings a lot of pollution emissions, which greatly increases the cost of the entire activated carbon production. In the production process of activated carbon, a large amount of combustible gases are produced: such as CO, H 2 、CH 4 、C 2 h 4 , these gases are partly burned to maintain the temperature required for the normal production of the activation furnace, and the rest are discharged into the atmosphere along with the flue gas, which not only causes a waste of coal resources, but also pollutes the environment
