Abstract
The invention discloses a pulse catalyst device. A plurality of elements (1) are piled up from top to bottom to form a monomer (2) with a continuous necking positions and enlarging positions, or the monomers are mutually combined to form an assembly (3), wherein the element (1) is composed of a hollow conical body and catalyst filled in the hollow conical body. The pulse catalyst device is filled above the outlet of a fixed bed reactor so as to form continuous single or multiple necking and enlarging single channel or multiple channels which contain the catalyst at the outlet position; when reactant flows in the channel, channel area for flowing the reactant is regularly reduced and enlarged repeatedly. When reactant gas and liquid flow in the channel which is filled with the catalyst and arrive at the necking position, gas velocity is maximum; when the reactant gas and the liquid flow to the enlarging position, the gas velocity is minimum, thus pulse is formed by repeated flow; along with continuous production of the pulse, gas generates strong turbulence in the flow process so as to greatly strengthen mass transfer between gas and liquid, thereby obviously improving catalytic reaction effect and improving the quality and the efficiency of the resultant.
Description
Technical field
The present invention relates to catalyst-assembly, relate in particular to the pulse catalyst-assembly that is used for fixing in the bed bioreactor.
Background technology
As everyone knows, solution-air catalytic reaction efficient in the fixed bed reactors just is directly connected to quality and the efficient that gas-liquid reaction generates product, and particularly the solution-air catalytic reaction efficient at fixed bed reactors outlet position directly influences the quality of gas-liquid reaction generation product and the key factor of efficient especially.At present, velocity variations is little because fixed bed reactors inner outlet position solution-air flows in catalyst relatively, can not form turbulence state between the solution-air of outlet position, and mass transfer effect is not high between the solution-air, thereby has directly restricted catalytic reaction efficient.
Summary of the invention
At above-mentioned problems of the prior art, the invention provides a kind of fixed bed reactors outlet pulse catalyst-assembly position, that can significantly improve solution-air catalytic reaction efficient and quality that is filled in.
Pulse catalyst-assembly of the present invention is filled in fixed bed reactors outlet position, it is piled up up and down by several cell cubes and forms the monomer that has continuous bottleneck and expansion place or be combined to form assembly mutually by monomer, and described cell cube is formed by hollow-cone body and the catalyst that is filled in the hollow-cone body.
Described catalyst is formed by honeycomb ceramic carrier and the active component that is coated on the carrier, described honeycomb ceramic carrier can be selected according to the needs of the catalyzed chemical reaction in the different reaction towers, can be various materials such as aluminium oxide, silica, zirconia, cordierite, mullite, honeycomb hole is shaped as the pass that ceramic honey combs such as delthyrium, cubic hole, hexagon ring, circular port can moulding in the described honeycomb ceramic carrier, hole density is more than 100 orders, and described active constituent also is to determine according to the catalyzed chemical reaction in the various differential responses towers.
Described hollow taper body and function pottery or plastics are made.
Expansion place of described monomer and bottleneck diameter difference are 0.5-5 times of bottleneck, and preferably 1-2 times, the 0.5-3 that described cell cube height is an expansion place diameter times, preferably 0.8-2 doubly.
Described honeycomb ceramic carrier diameter specifications is: 3-50mm.
Above-mentioned pulse catalyst-assembly is filled in fixed bed reactors outlet position, thereby can form continuous necking down and expansion and single or multiple passages that contain catalyst at the outlet position, when reactant flows in passage, the reactant flow channel area will be rule repeat dwindle, enlarge.When flowing to bottleneck in reactant gas and liquid have been filled the passage of catalyst, it is maximum that gas flow rate reaches; When flowing to expansion place, it is minimum that gas flow rate reaches, flow so repeatedly and form pulse, along with pulse constantly produces, gas can produce strong turbulent flow in traveling process, make the mass transfer between the solution-air strengthen greatly, improve the catalytic reaction effect, improve the quality and the efficient of product thereby can show.
