DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to an adsorber for cleaning flue gases of a furnace, comprising a housing having a flue gas inlet and a flue gas outlet and further comprising an adsorption medium chamber arranged in the housing and having a fill socket extending upwardly from the top of the housing and a removal device extending downwardly from the bottom of the housing, wherein the chamber is delimited at the inlet side and at the outlet side by substantially vertical, gas-permeable walls and comprises a substantially vertical, gas-permeable partition and wherein the wall at the inlet side is a louver wall and extends upwardly to the level of the fill socket.
Such adsorbers, known from practice, have been used in the past in connection with power plants and large garbage incinerating facilities. The resulting considerable gas throughput requires a great constructive expenditure. Thus, an application in connection with furnaces of smaller output has been proven to be uneconomical.
It is an object of the present invention, to provide an adsorber of the aforementioned kind that can be used in a simple and economical manner also in connection with furnaces of a smaller output.
SUMMARY OF THE INVENTION
As a solution to this object, the adsorber according to the present invention is characterized in that the gas-permeable wall at the inlet side of the adsorption medium chamber is a lower wall and extends upwardly to the level of the fill socket, while the wall at the outlet side is a slotted screen connected with a slanted, non-gas-permeable wall to the fill socket whereby the flue gas outlet is located opposite the non-gas-permeable wall.
The inventive adsorber for purifying flue gases of a furnace is characterized by: delimiting the chamber at the inlet side and at the outlet side; slanted non-gas-permeable wall; level of the fill socket; slanted, non-gas-permeable wall to the fill socket, wherein the flue gas outlet is located opposite the slanted non-gas-permeable wall.
The flue gas inlet is guided into the housing at an upper portion thereof, and between the flue gas inlet and the louver wall a baffle plate is arranged.
The baffle plate extends to an upper end of the housing.
The vertical gas-permeable partition is a wall with holes.
The adsorber further comprises a removable adsorption medium filling container detachably connected to the fill socket.
The adsorber further comprises a filling sensor connected to the fill socket, wherein the fill socket comprises a closure device controlled by the sensor.
The filling container comprises a closure device at an outlet side thereof.
The adsorber further comprises a removable adsorption medium removal container, wherein the removal device has a removal funnel that comprises a closure device and is detachably connected to the removable adsorption medium removal container.
The removal container comprises a closure device at an inlet side thereof.
The louver wall at the inlet side ensures a very uniform distribution of the flue gases to be cleaned across the height of the adsorption medium chamber. The louver wall extends to the level of the inlet socket whereby the flue gases at this location can also enter between the louver wall and the fill socket into the adsorption medium bed. They are guided at a slant downwardly through the upper portion of the bed by the oppositely arranged slanted non-gas-permeable wall. This area thus provides optimal flow conditions, so that no overheated zones will result, without requiring additional inserts. The slotted screen at the outlet side is of an extremely simple construction. The purified flue gases are guided downstream of the slotted screen in an upward direction to the flue gas outlet. A direct impact of the flue gas outlet is prevented by the slanted, non-gas-permeable wall which extends between the slotted screen and the fill socket.
The simple and space-saving construction of the adsorber which however ensures a very good purifying action for the flue gasses allows its application in connection wi
