Direct water-supply type heat storage activation method and direct water-supply type heat storage activation furnace

Abstract

The invention relates to a direct water-supply type heat storage activation method and a direct water-supply type heat storage activation furnace. Water is directly injected into heat storage chambers of the activation furnace, and energy compensation is additionally increased for the heat storage chambers injected with the water; and the energy compensation makes up the temperature reduction of the tops of the heat storage chambers after water injection so as to ensure the working temperature of activation zones in the main bodies of the activation furnace. The direct water-supply type heat storage activation furnace comprises two main bodies of the activation furnace, a combustion chamber, two heat storage chambers, two upper connected gas flues, a discharge flue, two water supply devices and an energy compensation device. In the scheme of the invention, the water can be directly injected into the heat storage chamber of the activation furnace to directly save a steam boiler for generation water vapor for the activation furnace, thereby not only greatly reducing the cost of a production device, but also saving a great amount of energy sources consumed for generating the water vapor and greatly reducing the production cost of active carbon. The direct water-supply type heat storage activation method and the direct water-supply type heat storage activation furnace have the advantages of having simple and convenient reconstruction, less fund input and quick response, fully utilizing renewable energy sources, and avoiding increasing new heat energy compensations.

Description

technical field [0001] The invention relates to a production method and production equipment of activated carbon, in particular to a direct water-feeding heat storage activation method and a direct water-feed heat storage activation furnace. Background technique [0002] Most of the equipment and methods for producing activated carbon in the prior art use a steam boiler to generate water vapor and inject it into the activation furnace to realize activation and complete the production of activated carbon. This production method and equipment need a steam boiler to provide Steam, this not only greatly increases the cost of production equipment, the operating cost of the steam boiler is often several times the operating cost of the activation furnace, not only needs to consume a lot of energy to generate water steam, but also greatly increases the production cost of activated carbon, and the steam Serious air pollution of boilers, especially coal-fired steam boilers, is the mai...

[0002] Most of the equipment and methods for producing activated carbon in the prior art use a steam boiler to generate water vapor and inject it into the activation furnace to realize activation and complete the production of activated carbon. This production method and equipment need a steam boiler to provide Steam, this not only greatly increases the cost of production equipment, the operating cost of the steam boiler is often several times the operating cost of the activation furnace, not only needs to consume a lot of energy to generate water steam, but also greatly increases the production cost of activated carbon, and the steam Serious air pollution of boilers, especially coal-fired steam boilers, is the main target of shutting down the country's implementation of emission reduction targets; through research, it is found that, taking saddle-type activation furnace (Sleep type) as an example, the temperature requirement at the top of the regenerator in the activation furnace is At 1000-1100 degrees, the temperature of the activation zone in the activation furnace can be effectively ensured at such a temperature to meet the conditions of the production process. Since the top of the regenerator is made of heat-resistant concrete components, and the interior is made of ordinary clay for fire resistance. It is made of bricks. When the temperature at this point is higher than 1150 degrees, it is very easy to be burned, which directly affects the service life of the regenerator and the main body of the activation furnace. When the temperature at this point is lower than 1000 degrees, the activation will be directly reduced. The temperature of the upper part of the activation zone in the main body of the furnace, thus affecting the activation effect of the activation product
