Description
Technical field
The present invention relates to the aerosol filtrations of air cleaning and iodine method for adsorbing and purifying and equipment, and in particular to one kind has both
The integration filter absorber of radioaerosol filtering and iodine absorption.
Background technique
The ventilating system or radioactive gas recovery system of nuclear power plant or other nuclear facilities use high efficiency filter respectively at present
Device is adsorbed with being filtered to remove the radioaerosol in air or gas using the iodine adsorber filled by impregnated granules active carbon
It purifies radioiodine (including the radioiodines chemical combination such as iodine, organic iodine object), these high efficiency particulate air filters and impregnated granules activity
The radioactivity amount that charcoal iodine adsorber is filtered or adsorbed according to it is divided into different types of radioactive waste and is located accordingly
Reason and final disposal simultaneously generate final Waste disposal expense.
Summary of the invention
The purpose of the present invention is to solve defects of the existing technology, provide one kind and have both radioaerosol filtering
And the integration filter absorber of iodine absorption.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A kind of integration filter absorber having both radioaerosol filtering and iodine absorption, including shell and setting exist
The intracorporal filtering absorption filter element of shell, the filtering absorption filter element include filter element shell, the both-side opening of filter element shell, filter element shell
Side opening be equipped with multiple activated carbon fibre sticks, the inner wall of the both ends of activated carbon fibre stick and filter element shell connects, adjacent
Activated carbon fibre stick between be equipped with supporting layer；
The filtering absorption filter element is mounted in adsorber housing body, and the side of adsorber housing body has air inlet, air inlet
It is connected to the inner cavity of the inner cavity of adsorber housing body and filter element shell.
Further, the activated carbon fibre stick impregnates one or both of triethylene diamine or potassium iodide solution.
Further, the activated carbon fibre stick is carbonized by the fiber-like material of porous property.
Further, the activated carbon fibre stick is carbonized by chemical fibre.
Further, the supporting layer is wavy, the top and bottom of supporting layer and the surface of adjacent active Carbon fibe stick
Contact.
Further, the adsorber housing body connects handle.
The invention has the benefit that the filtering collector has both radioaerosol filtering function and adsorption cleaning radiation
Property iodine function, does not change the outer dimension of presently used high efficiency particulate air filter and iodine adsorber, is not increasing system reform expense
Under the premise of for nuclear power plant and other nuclear facilities ventilating system and gas handling system it is efficient to replace using respectively at present
Filter and iodine adsorber, on the one hand can save the operation of nuclear power plant and other nuclear facilities ventilating systems and gas handling system at
This, on the other hand can save the processing cost of disposal of final radioactive waste.
Detailed description of the invention
