Abstract
The utility model discloses a synthetic ammonia vent gas gas-liquid separator for liquefied methane. The gas-liquid separator mainly comprises a drum body, an upper end enclosure, a lower end enclosure, a flange, a pair of bolt and nut, a gas and liquid mixing inlet pipe, a liquefied methane outlet pipe, a nitrogen outlet pipe, a fixed pore plate and silk screens. The liquefied methane which is subjected to copious cooling and nitrogen enter into the drum body through the gas and liquid mixing inlet pipe, the liquefied methane is discharged from the liquefied methane outlet pipe by virtue of gravity, the small droplets of liquefied methane carried by the nitrogen is removed by filtration by a plurality of silk screens when passing through the pore plate and the silk screens and is discharged from the liquefied methane outlet pipe, and clean nitrogen is sent back to an ammonia synthesis system. The separator disclosed by the utility model has the characteristics of simple structure, convenience in operation, good separation effect, and the like.
Description
Technical field
The utility model relates to synthetic ammonia emptying gas liquefied methane separator, is directly involved in a kind of synthetic ammonia emptying gas liquefied methane gas-liquid separator.
Technical background
Domestic more than 400 synthesis ammonia plants have generally built up the synthetic ammonia emptying gas recycle device, and isolated ammonia and hydrogen return to synthesis ammonia system and produces urea, and remaining nitrogen, methane gas enter atmosphere or deliver to three wastes boiler combustion.Our company is after deamination is carried hydrogen, set up the liquefied methane device, by subzero treatment commodity selling is done in methane gas liquefaction, nitrogen is sent to ammonia synthesis system, mixture behind the deep cooling needs a kind of gas-liquid separation device, with liquid methane and nitrogen separation, and traditional gas-liquid separator, tiny drop enters next procedure with nitrogen, and the gas-liquid separator of seeking a kind of high separating efficiency is very necessary.
Summary of the invention
The purpose of this utility model is exactly with liquid methane and nitrogen effective separation, has avoided fine drop to enter next procedure with nitrogen.The purpose of this utility model is achieved in that synthetic ammonia emptying gas liquefied methane gas-liquid separator, has cylindrical shell, upper cover, low head, flange, bolt and nut, the gas-liquid mixed inlet tube, the liquid methane outlet, nitrogen outlet pipe, cylindrical shell is the cylinder that is welded with the stainless steel coiled sheet, lower end welding low head, upper end outside weldings flange, the upper cover flange, bolt and nut is connected with cylindrical shell, STH welding gas-liquid mixed inlet tube outside the cylindrical shell first half, at low head center drilling welding liquid methane inlet tube, at upper cover center drilling welding mixed gas outlet pipe, inside, upper end is welded with the fixing hole plate, is fixedly spreading the multilayer stainless steel cloth above the orifice plate.
Liquid methane and nitrogen through subzero treatment enter from the gas-liquid mixed inlet tube, most of liquid methane is discharged from the outlet of low head liquid methane, nitrogen is carried a small amount of fine drop methane secretly through orifice plate, rust steel wire, fine drop is discharged from lower end liquid methane outlet by the stainless steel cloth filtering, nitrogen is discharged from nitrogen outlet pipe, has reached the effective separation of synthetic ammonia emptying gas liquefied methane device liquid methane and nitrogen.
Description of drawings
Accompanying drawing shows the structural representation of a kind of synthetic ammonia emptying gas liquefied methane of the utility model gas-liquid separator, is described further below in conjunction with accompanying drawing.
The specific embodiment:
Accompanying drawing shows the structure of a kind of synthetic ammonia emptying gas liquefied methane of the utility model gas-liquid separator: have cylindrical shell 1, upper cover 2, low head 3, flange 6, bolt and nut 7, gas-liquid mixed inlet tube 8, liquid methane outlet 9, nitrogen outlet pipe 10.Described cylindrical shell 1 is the cylinder that the corrosion resistant plate with thickness 16 mm rolls into, 1 meter of diameter, high 1.6 meters, at the lower end of cylindrical shell 1 welding low head 2, inner 0.3 meter is welded and fixed orifice plate 4 in cylindrical shell 1 upper end, fixedly spreading multilayer stainless steel cloth 5 above the orifice plate 4, in the outside, cylindrical shell 1 upper end, upper cover 2 welded flanges 6, be connected with cylindrical shell 1 with bolt and nut 7, from 0.5 meter perforate welding gas-liquid mixed inlet tube 8 suitable for reading, be φ 159 * 4 mm, the stainless steel tube of long 150 mm on cylindrical shell 1 top, at low head 2 center drillings welding liquid methane outlet 9, be φ 133 * 3.5 mm, the stainless steel tube of long 150 mm is at upper cover 2 center drillings welding nitrogen outlet pipe 10, be φ 108 * 3.5 mm, the stainless steel tube of long 150 mm.
Operation principle
Synthetic ammonia emptying gas is except after ammonia carries hydrogen, through subzero treatment, methane is liquefied and is liquid, the mixture of nitrogen and liquid methane enters cylindrical shell 1 inside from gas-liquid mixed inlet tube 8, liquid methane falls into cylindrical shell 1 bottom by gravity, enter storage tank from 9 discharges of liquid methane outlet, a small amount of fine drop shape methane of carrying secretly in the nitrogen is through fixing orifice plate 4 and multilayer stainless steel cloth 5 time, fallen into cylindrical shell 1 bottom by 5 filterings of multilayer stainless steel cloth, discharge from liquid methane outlet 9, clean nitrogen is discharged from top nitrogen outlet pipe 10 and is delivered to ammonia synthesis system.
Characteristics of the present utility model, because fixedly orifice plate 4 and multilayer stainless steel cloth 5 have been set up in inside, the fine drop shape liquid methane that nitrogen is carried secretly is reached the effective separation of synthetic ammonia emptying gas liquefied methane by filtering, and is simple in structure, easy to operate.
