Abstract
The utility model relates to a gas distributor, in particular to gas distributor for a fixed-bed reactor. The gas distributor for a fixed-bed reactor comprises a base, leg supports and a gas distributor tray; wherein leg supports are arranged below the base and the gas distribution tray is arranged above the base. The gas distributor for a fixed-bed reactor is rational in structure, easy to manufacture and low in manufacturing expense, can distribute gas evenly so as to improve the production efficiency.
Description
Technical field
The utility model relates to a kind of gas distributor, the gases used distributor of particularly a kind of fixed bed type reactor.
Background technology
Fixed bed type reactor is widely used in the technological processes such as chemical industry, metallurgy, energy project, environmental protection, gas distributor is as one of critical component of fixed bed type reactor, the uniformity coefficient of its gas distribution can influence the operation running of fixed bed type reactor greatly, particularly along with process units maximizes day by day, enlarge-effect is even more serious.Can select different gas distributors or gas distributor system for use according to different technological requirements in the practical application.
At present usually the major defect that exists of the gas distributor that adopts is: circulation area Xiao Yi stops up, and is one with the reactor weldering, is difficult for disassembly, cleaning after stifled, with raw material gas inlet apart from weak point, the carbon deposit after stifled easily enters feed pipe, and whole feed system is brought pollution.As notification number is a kind of gas distributor that the Chinese patent of CN2705231 is mentioned, it adopts by the distributor cylindrical shell, the side direction annular space, the annular vertical baffle, annular baffle and sieve plate are formed the technical scheme of gas distributor, its advantage is: 1, current-sharing effect is better, can make the distribution of gas effect that reaches desirable in the axial flow fixed bed reactor; 2, simple in structure, easy for installation.But this distributor also exists following shortcoming: 1, welded together with the air inlet of reactor, be unfavorable for the cleaning of gas distributor and clean 2, gas distributor and air inlet be apart from weak point, carbon deposit after stifled easily enters air inlet, causes the pollution of whole feed system easily.
Summary of the invention
The utility model provides a kind of fixed bed type reactor gas distributor of being convenient to clean and maintenance at the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of fixed bed type reactor gas distributor is characterized in that, is made up of base, supporting leg and gas panel; Described base is arranged with supporting leg, is provided with gas panel above the base.
Described gas panel is surrounded by the uniform Turbogrid plates of lattice dimensions.
Described gas panel is a drum shape.
Described base is cylindrical.
Described gas panel is fixedlyed connected with base.
Described base diameter is the 10%-70% of fixed bed reactors diameter, and the height of gas panel is the 10%-30% of fixed bed reactors diameter, and the internal diameter of gas panel is the 7%-67% of fixed bed reactors diameter, and the height of supporting leg is 30-150mm.
Preferably, base diameter is the 25%-45% of fixed bed reactors diameter, and the height of gas panel is the 15%-25% of fixed bed reactors diameter, and the internal diameter of gas panel is the 22%-42% of fixed bed reactors diameter, and the height of supporting leg is 50-110mm.
The operation principle of this gas distributor of brief description: unstripped gas enters fixed bed reactors by reactor inlet, because the reaction gas flow speed ratio is very fast, most of unstripped gas vertically enter the gas distributor gas panel, and unstripped gas evenly distributes to the tubulation that catalyst is housed behind gas panel.Wherein some unstripped gas is from entering the below tubulation of gas distributor between supporting leg and the base, thereby the unstripped gas that guarantees whole catalyst tubulation evenly distributes.
When producing carbon deposit, carbon deposit at first assembling at gas panel, can keep catalyst not contaminated within a certain period of time, prolongs the service time of catalyst, increases production capacity.When needs cleaning carbon deposit, only need that gas distributor is taken out cleaning and get final product.
The utility model is compared with the prior art structure, and this product belongs to a kind of brand-new design.It has the following advantages: 1, rational in infrastructure, make simple, manufacturing cost is low, 2, can well gas evenly be distributed, guarantee the reasonable utilization of catalyst in the every tubulation, avoid in the service life of having guaranteed catalyst, enhancing productivity because of the uneven difference that causes the catalyst applying working condition of distribution of gas.
