Abstract
The utility model discloses a loxygen discharge evaporator for an air separation unit of an oxygen producing plant, and aims to solve the problems that the cement base of a conventional jet evaporator is fractured easily in the cold, the safety factor is low and the discharge noise is high. The loxygen discharge evaporator comprises a discharge pipe, an oxygen inlet pipe, an air or nitrogen inlet pipe and a uniform distribution board; the discharge pipe is arranged vertically, a bell mouth with a bigger upper part and a smaller lower part is connected to the upper end of the discharge pipe, and the lower end is sealed; the oxygen inlet pipe passes through the side wall of the discharge pipe to be communicated with the discharge pipe; the air or nitrogen inlet pipe passes through the lower bottom surface of the discharge pipe to be communicated with the discharge pipe; in the discharge pipe, the oxygen inlet pipe is separated from the air or nitrogen inlet pipe by the uniform distribution board; and a plurality of small holes are formed in the uniform distribution board. In the utility model, the uniform distribution board is additionally arranged, so that the problem of high noise when a nozzle is adopted is solved; the bell mouth is connected to the upper end of the discharge pipe, so that after heat exchange of loxygen and dry air or clean low-pressure nitrogen, the mixed gas can be quickened to be mixed with the atmosphere more easily, and the safety factor of discharge is improved; and the whole evaporator is supported by a steel bracket, so that the cement base can not be fractured in the cold.
Description
Technical field
The utility model relates to the liquid oxygen discharging evaporimeter of a kind of oxyen manutactory air separation unit.
Background technology
Oxyen manutactory's air separation unit need discharge liquid oxygen when parking or technology adjustment, adopt open injection evaporimeter at present, liquid oxygen is sent into by fluid injector and is stockpiled container, air or nitrogen tube feed and stockpile container, mix with liquid oxygen from the bottom up, make the liquid oxygen gasification, the mist after the gasification is collected after discharged by the horn mouth that stockpiles the container top.There is following defective in this device: 1, stockpile container and directly be installed on the cement pedestal, the liquid oxygen temperature is extremely low, and the cement pedestal easily freezes brokenly; 2, it is open stockpiling container top, and safety coefficient is low, and discharge noise is big.
The utility model content
The purpose of this utility model is to overcome the prior art defective, and a kind of novel liquid oxygen discharging evaporimeter is provided.
The technical solution of the utility model is achieved in that novel liquid oxygen discharging evaporimeter, form by delivery pipe, oxygen inlet pipe, air or nitrogen inlet pipe, uniform board, delivery pipe is erect and upper end open, the lower end sealing, the oxygen inlet pipe passes the delivery pipe sidewall and feeds delivery pipe, air or nitrogen inlet pipe pass the delivery pipe bottom surface and feed delivery pipe, are separated with uniform board between the inherent oxygen inlet pipe of delivery pipe and air or the nitrogen inlet pipe, have a plurality of apertures on the described uniform board.
Further, be connected to up-small and down-big horn mouth on the described delivery pipe.
Further, described delivery pipe bottom also is connected to the leakage liquid collecting region, and leakage liquid collecting region bottom is by leakage liquid discharged leakage liquid.
Further, described novel liquid oxygen discharging evaporimeter supports with steelframe.
Further, described novel liquid oxygen discharging evaporimeter is made of aluminium or stainless steel.
The utility model increases uniform board, makes liquid oxygen and dry air or clean low-pressure nitrogen carry out heat exchange more fully, becomes oxygen, has solved the big problem of noise when adopting nozzle; Delivery pipe upper end is connected to horn mouth, and the mist after liquid oxygen and dry air or the clean low-pressure nitrogen heat exchange is quickened, and is easier to mix with atmosphere, and safety coefficient is discharged in raising; The amount of liquid that is not gasified totally after the transformation is less, and whole evaporimeter directly is not contained on the concrete pedestal, supports by steel bracket, can not cause the concrete pedestal bursting by freezing.Even if the residual liquid oxygen of minute quantity is arranged the bursting by freezing of delivery pipe base plate, the leakage liquid collecting region of delivery pipe bottom also can be caught liquid oxygen, has further guaranteed the security of discharging.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure, the 1-delivery pipe; 2-oxygen inlet pipe; 3-air or nitrogen inlet pipe; The 4-uniform board; 5-leakage liquid collecting region; 6-leakage liquid delivery pipe; The 7-horn mouth.
The specific embodiment
Be further described below in conjunction with accompanying drawing:
As shown in the figure, novel liquid oxygen discharging evaporimeter, form by delivery pipe 1, oxygen inlet pipe 2, air or nitrogen inlet pipe 3, uniform board 4, delivery pipe 1 erects and the upper end is connected to up-small and down-big horn mouth 7, the lower end sealing, oxygen inlet pipe 2 passes delivery pipe 1 sidewall and feeds delivery pipe, and air or nitrogen inlet pipe 3 pass delivery pipe 1 bottom surface and feed delivery pipe 1, be separated with uniform board 4 between delivery pipe 1 inherent oxygen inlet pipe 2 and air or the nitrogen inlet pipe 3, have a plurality of apertures on the described uniform board; Described delivery pipe bottom also is welded with leakage liquid collecting region 5, and leakage liquid collecting region 5 bottoms are by leakage liquid delivery pipe 6 discharging leakage liquids; Described novel liquid oxygen discharging evaporimeter is welded on the steelframe; Described novel liquid oxygen discharging evaporimeter is made of aluminium or stainless steel, with low temperature resistant.
During work, oxygen inlet pipe 2 feeds liquid oxygen toward delivery pipe 1, air or nitrogen inlet pipe 3 up feed dry air or clean low-pressure nitrogen from the bottom, the two carries out heat exchange fully at uniform board 4, liquid oxygen is gasified rapidly, quicken to discharge from the horn mouth 7 at delivery pipe 1 top, the noise when having avoided adopting nozzle has improved the safety coefficient of discharging.Whole evaporimeter directly is not contained on the concrete pedestal, supports by steel bracket, can not cause the concrete pedestal bursting by freezing.Even if the residual liquid oxygen of minute quantity is arranged the bursting by freezing of delivery pipe base plate, the leakage liquid collecting region 5 of delivery pipe bottom also can be caught liquid oxygen, has further guaranteed the security of discharging.
