Abstract
The invention discloses a device for solving the problem of exceeding differential pressure of an inlet mixer of a synthesis ammonia oxygen-enriched compressor. The device is simple in structure, convenient to use, safe and reliable. Due to the adoption of the device, the problem of the exceeding differential pressure of the inlet mixer of the synthesis ammonia oxygen-enriched compressor is solved, breakdown maintenance is not required, and the normal operation of equipment is not influenced, so that the smooth and safe production is ensured. The device has the economic efficiency that: the mixer is subjected to breakdown maintenance once every two months, more than five times every year, and for 5 hours every time; the device produces18.75 tons of liquid ammonia hourly, and the price of each ton of liquid ammonia is 3,150 yuan approximately; and the annual increase benefit of the device is 1.5 million yuan approximately.
Description
Technical field
The present invention relates to a kind of chemical industry Ammonia Production equipment, particularly a kind ofly solve the device that synthetic ammonia oxygen enrichment suction port of compressor mixing tank pressure reduction exceeds standard.
Background technology
Although all adding strainer on air line He on the oxygen enrichment pipeline, but while both and together entering synthetic ammonia oxygen enrichment suction port of compressor mixing tank, 200 order filtering nets just have latch up phenomenon in two months mixing tanks, mixing tank gangway pressure reduction surpasses prescribed value, affect the oxygen enrichment compressor flowrate, have to break-down maintenance.
Summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of simple in structure, esy to use, safe and reliable, solves the device that synthetic ammonia oxygen enrichment suction port of compressor mixing tank pressure reduction exceeds standard.
The present invention is achieved through the following technical solutions:
A kind ofly solve the device that synthetic ammonia oxygen enrichment suction port of compressor mixing tank pressure reduction exceeds standard, it is characterized in that: increase valve A and valve B before and after mixing tank, and increase adds two-layer 200 order Stainless Steel Cloths again with the by-pass of valve C and valve D between valve C and valve D on by-pass; Add valve E and from the pipeline A that draws a band valve F after root valve E, encounter on the by-pass that newly adds at the root that removes the dry gas seals pipeline before mixing tank; Add valve G at the root that turns back to the anti-surge pipeline of mixing tank from the outlet of high and low cylinder pressure, and the pipeline B that draws a band valve H before root valve G encounters on the pipeline of suction port of compressor.
The working method of described device, it is characterized in that: when mixing tank gangway pressure reduction exceeds standard, first open valve C and valve D on by-pass, then switch valve E and valve F on pipeline A, switch simultaneously valve G and the valve H of pipeline B, close finally valve A and the valve B of mixing tank front and back.
Beneficial effect of the present invention: this apparatus structure is simple, esy to use, safe and reliable, after adopting this device, solve synthetic ammonia oxygen enrichment suction port of compressor mixing tank pressure reduction and exceeded standard, do not needed break-down maintenance, the equipment that do not affect normally moves, thereby guarantees safety in production smoothly; Economic benefit: mixing tank break-down maintenance in every 2 months 1 time, want break-down maintenance more than 5 times every year, and every less important stopping 5 hours, per hour produce 18.75 tons of liquefied ammonia less, and rear annual approximately 1,500,000 yuan of the benefits that increase of this device are adopted in 3150 yuan of left and right of liquefied ammonia per ton.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing 1 is structural representation of the present invention;
In figure, 1 mixing tank, 2 valve A, 3 valve B, 4 valve C, 5 valve D, 6 Stainless Steel Cloths, 7 by-passes, 8 dry gas seals pipelines, 9 valve E, 10 valve F, 11 pipeline A, 12 high and low cylinder pressures, 13 anti-surge pipelines, 14 valve G, 15 valve H, 16 pipeline B, 17 air lines, 18 oxygen enrichment pipelines, 19 suction port of compressor pipelines.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment relates to a kind of device that synthetic ammonia oxygen enrichment suction port of compressor mixing tank pressure reduction exceeds standard that solves, it is characterized in that: in mixing tank 1 front and back, increase valve A2 and valve B3, and increase adds two-layer 200 order Stainless Steel Cloths 6 again with the by-pass 7 of valve C4 and valve D5 between valve C4 and valve D5 on by-pass 7; Add valve E9 and from the pipeline A11 that draws a band valve F10 after root valve E9, encounter on the by-pass 7 that newly adds at the root that removes dry gas seals pipeline 8 before mixing tank 1; Add valve G14 at the root that turns back to the anti-surge pipeline 13 of mixing tank 1 from 12 outlets of high and low cylinder pressure, and the pipeline B16 that draws a band valve H15 before root valve G14 encounters on suction port of compressor pipeline 19.When mixing tank 1 gangway pressure reduction exceeds standard, first open valve C4 and valve D5 on by-pass 7, switch again valve E9 and valve F10 on pipeline A11, switch simultaneously valve G14 and valve H15 on pipeline B16, close finally valve A2 and the valve B3 of mixing tank 1 front and back, mixing tank is pulled down to overhaul get final product.
