Abstract
The invention discloses an oxygen rectifying tower with convective sieve plates, comprising an upper tank and a lower tank which are welded together; a plurality of layers of stacked convective sieve plate devices are arranged in the upper tank; a re-boiler unit is further mounted in the lower tank. The oxygen rectifying tower provided by the invention can effectively prevent impurities such as CnHm and NO2 from accumulating in fins by above manner so as to increase plate efficiency and product oxygen extraction ratio, and reduce harmful impurities of raw materials entering auxiliary coolers.
Description
Technical field
The present invention relates to the plant equipment field, particularly relate to a kind of convection current sieve plate rectifying oxygen column.
Background technology
The major product of air separation plant is oxygen and nitrogen.Oxygen is the material that all lived bodies are depended on for existence on the earth. it is easy to and other material generation oxidation reactions, and emits great amount of heat.Therefore, oxygen is used widely in departments such as metallurgy, chemical industry, the energy, machinery, national defense industry as oxidant and combustion adjuvant.And cryogenic liquid has superiority at storage and transporter mask, so the demand of low temperature liquid oxygen is more and more, and it is low that the sky branch through routine adds the oxygen column recovery rate that liquefaction process uses in accounting for, and fin gathers impurity easily in the tower.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of convection current sieve plate rectifying oxygen column, can effectively prevent impurity gathering in fin such as CnHm and NO2, improves plate efficiency, improves the product oxygen extraction ratio, reduces the raw material objectionable impurities and gets into auxilliary cooler.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of convection current sieve plate rectifying oxygen column is provided; This convection current sieve plate rectifying oxygen column comprises upper tank body and the lower tank that welds together; Be provided with the convection current sieve apparatus of multilayer stack in the said upper tank body, be equipped with the reboiler unit said also comprising in the lower tank.
Preferably, said convection current sieve apparatus comprises sieve plate, carrying bolt and bracing frame, and support frame as described above is fixed in the upper tank body inwall, and bracing frame is provided with carrying bolt, is installed with a plurality of sieve plates on the carrying bolt, and passes through fixed by nut.
Preferably, lean on the position of convection current sieve apparatus bottom to be provided with liquid dish in the said upper tank body.
Preferably, the outer wall of said upper tank body leans on the position of upper and lower end parts to be respectively equipped with correcting block.
Preferably, said reboiler unit also is provided with the reboiler unit rack, and said reboiler unit is fixed in the lower tank through the reboiler unit rack.
Preferably, be equipped with the liquid in-out mouth on said upper tank body and the lower tank.
Preferably, be provided with the tank body bracing frame bottom the said lower tank.
The invention has the beneficial effects as follows: a kind of convection current sieve plate of the present invention rectifying oxygen column, can effectively prevent impurity gathering in fin such as CnHm and NO2, improve plate efficiency, improve the product oxygen extraction ratio, reduce the raw material objectionable impurities and get into auxilliary cooler.
