Abstract
The utility model provides a tool device for testing the pressure of a sieve tray of a titanium carbonizing tower, comprising two circular cover-shaped cavities which are connected with each other by a thick flange. The thick flange is provided with a machined sealing surface, and the width of the diameter of the thick flange covers the circumference of the sealing surface of the sieve tray to be capable of bearing the pressure of the pressure test and guaranteeing the sealing performance of the flange; an upper base plate and a lower base plate of each circular cover-shaped cavity are made from thin plates, and each plate is welded with a rib plate which is taken as a reinforcing rib; and each circular cover-shaped cavity is provided with an outward-raised cylinder body, the dimension of which is matched with that of an overflow pipe on the sieve tray. The tool device can be used for the sieve tray manufactories to test the pressure without needing to be transported to the use field, thereby reducing the great loss caused by unqualified products.
Description
Technical field
The utility model relates to the pressure test that system alkali nucleus equipment carbonators sieve tray is made, and is widely used in the large-scale tower tray of carbonators and makes processing industry.
Background technology
Carbonators is a system alkali nucleus equipment, and carbonation process is " heart " operation in the soda ash manufacture process.Along with the maximization of carbonators, the also corresponding raising of its productive capacity, as Φ 2800/3000, Φ 3000/3400 sieve plate carbonators, the ability of these large-scale carbonators has all reached 300t/d output, is newly-built in recent years and the carbonators of enlarging Sodium Carbonate Plant first-selection.
Along with the maximization of carbonators, its core component sieve tray manufacture difficulty significantly increases.General sieve tray is transported to and uses assembled on site, pressure testing, use after manufacturing plant makes.If the sieve tray sealing problem occurs, do not possess the condition of on-the-spot alignment, dismantle, transport back manufacturing plant's finishing again.Like this can close down at equipment, aspect such as transportation causes tremendous loss.The sieve tray sealing detects extremely important before manufacturing plant dispatches from the factory.
The structure of titanium system carbonators sieve tray is, the periphery tray diameter of sieve plate is φ 2000～φ 4000, and thickness is at 3-10mm.Sieve plate is the structure in equilateral triangle cloth hole, welding gusset in the back side behind the sieve plate, and two run-down pipe vertical weldings are connected to sieve tray.
Sieve tray carbonators applying working condition:
1) design pressure 0.06MPa; On-stream pressure 0.033MPa;
2) design temperature is 75 ℃; 35 ℃～75 ℃ of operating temperatures;
3) sieve tray carbonators hydraulic test pressure 0.1MPa;
4) sieve tray carbonators processing medium: ammonial brine, in and water etc.
The utility model content
The utility model purpose is to propose a kind of fitting device of major diameter carbonators titanium sieve tray pressure test.
The technical solution of the utility model: the fitting device of major diameter carbonators titanium sieve tray pressure test: by two dome-shaped cavitys and all by thick flange connection.Thick flange is provided with the sealing surface of processing, and the width of the diameter of thick flange covers the sealing surface circumference of tower tray, bears the pressure of pressure test and guarantees the flange seal performance; The upper and lower bottom plate of dome-shaped cavity adopts thin plate, welds gusset onboard as reinforcement; The dome-shaped cavity be provided with sieve plate on the evagination cylindrical shell of coupling of size of run-down pipe.The utility model is according to sieve plate carbonators applying working condition and sieve plate carbonization tower tray structural design pressure test fitting device.The frock cavity need comprise the run-down pipe that firmly stretches out the tower tray face.Dome-shaped cavity diameter φ 1000～φ 4000.
The utility model beneficial effect is: sieve tray need not be transported to the use on-site voltage-measuring after manufacturing plant makes, and minimizing causes tremendous loss because of substandard product.And provide the sieve tray sealing before manufacturing plant dispatches from the factory, to carry out pick-up unit.

Excircle tower tray 1, sieve plate 2, reinforcement 3, run-down pipe 4; Thick flange 5, pressure testing chamber cylindrical shell 6, sealing surface circumference cavity are pressure testing chamber cover plate and base plate 7, pressure testing mouth 8.
Embodiment
Specify embodiment of the present utility model below:
Typical sieve tray tower tray 1 diameter phi 3540mm, seal f ace width 60mm, the sieve tray diameter is big, and the major diameter frock that designs under test pressure needs very big rigidity; Large-scale machined into is adopted at the sealing surface position of coordination.The sieve tray tower tray is equipped with run-down pipe 4, and the frock cavity need comprise the run-down pipe that firmly stretches out the tower tray face under test pressure.
1 sieve tray pressure testing chamber is equipped
The sieve tray diameter is φ 3540, and calculating structure for pressure test flange specification is δ 50 * φ 3420/3640, pressure testing chamber cylindrical shell δ 8 * DN3420, pressure testing chamber base plate δ 8 * φ 3440, reinforcement δ 10 * 80 (wide).Adopt arc assembly welding annulus, the Vehicle Processing sealing surfaces pieced together more.Two thick flanges and the cylindrical shell assembly of pressure testing chamber are welded after the bolted between thick flange.Carrying out pressure testing chamber cylindrical shell, base plate, reinforcement gusset etc. then welds.
2 pressure testing chamber impermeability tests
Assembled gasket between two pressure testing chamber flanges.Require to carry out pressure test the requirement of detected pressures test cavity structural strength composite design, the chamber of pressure testing simultaneously flange seal dependable performance according to the equipment pressure test.
3 sieve tray pressure testings
Sieve tray is packed in the pressure testing chamber, places pad, the clamp flange coupling bolt between tower tray and the two pressure testing chamber flanges.According to the equipment request for utilization, the pressurization of pressure testing chamber water-filling, test pressure 0.1MPa, the enough time of pressurize checks that the tensimeter indicated pressure remains unchanged in the process of the test, detects the tower tray sealing surface and does not find seepage.It is qualified that the hydraulic testing detects.
For guaranteeing that the sealing surface sealing property detects accurately, on the basis of hydraulic pressure pressure testing, carry out gas pressure test again, adopt nitrogen, test pressure 0.1MPa, the enough time of pressurize, the tensimeter indicated pressure remains unchanged in the process of the test, detects the tower tray sealing surface and does not find seepage.
Carry out the sealing of detection validation sieve tray sealing surface by structure for pressure test.Guarantee that sieve tray is to using on-the-spot back assembling, pressure test and equipment operation not to occur leaking.Thereby avoid the massive losses that in said process, brings because of seal failure.
Such test frock can be used for the impermeability test check as all clamp-type tower trays of carbonators tower tray class.
