Description
Technical field
The present invention relates to a kind of caulking gum film being applicable to low pressure operation and preparation method thereof, and a kind of cylinder type caulking gum curtain being applicable to low pressure operation, belong to smelting iron and steel technical field.
Background technique
Gas cabinet, as a necessaries of iron and steel enterprise's coal-gas recovering comprehensive utilization, plays an important role in low-carbon economy.
In recent years, due to a large amount of construction of gas cabinet project, domestic two-part rubber film sealing gas chamber for various reasons, constantly there is accident, its accident occurs mainly to cause at two sections, and once have an accident, its economic loss caused steel mill is also comparatively serious.
Before 2010, the rubber diaphragm sealing type gas chamber of domestic use is from 20,000 m
3below be mostly two-part sealing (referring to that gas storage pressure is divided into two sections), and abroad, unistage type rubber diaphragm sealing type gas chamber is but prevailing already.
Two-part rubber diaphragm sealing type gas chamber mainly contains following defect: the piston system complex structure of (1) two-part, and component is many, therefore makes, installs relative complex, and the unfavorable factor affecting security of operation is more; (2) the piston stroke scope of two-part gas holder is little, when the moment that piston driving T baffle plate runs, if velocity of piston is too fast, easily causes inclination; (3), there is pressure jump in two-part gas holder pressure transient, is a pressure when piston rises, and is again a pressure when piston driving T baffle plate rises, and the change of this pressure is general at about 0.6 ~ 0.8kPa; (4) easy decentraction when two-part gas cabinet piston and T baffle plate run, after running a period of time, easily cause piston drift phenomenon, especially piston driving T baffle plate and T baffle plate frequently rise, when falling, may cause this accumulation of drifting about and run down.
Relative to two-part rubber diaphragm sealing type gas chamber, one-part form rubber diaphragm sealing type gas chamber runs wherein owing to only there being piston, and its structure is simple, reliable, greatly can reduce maintenance, maintenance workload.Simultaneously due to pressure stability, primary air fan operating conditions is good, can reduce blower fan and exert oneself, and saves power consumption.In recent years, the domestic research to unistage type rubber membrane gas holder gets more and more, and has had preliminary application achievements, but for various reasons, the phenomenon of large single-stage formula rubber diaphragm sealing type gas chamber ubiquity piston drift.Wherein, large single-stage formula rubber diaphragm sealing type gas chamber refers to that nominal volume is more than or equal to 50,000 m
3unistage type rubber diaphragm sealing type gas chamber.For solving drifting problem, the mode that most unit have employed increases gas storage pressure carrys out control piston drift, and therefore the design pressure of domestic unistage type rubber diaphragm sealing type gas chamber is minimum is 3kPa.And external this type gas cabinet operating pressure can be low to moderate 1.8kPa, trace it to its cause, or really do not grasp the core content of technique due to domestic enterprise.
For thoroughly solving the problem of unistage type rubber diaphragm sealing type gas chamber piston drift, Professional visitors must carry out deep research to it.The main cause of rubber diaphragm sealing type gas chamber piston drift is caused to be unbalance stress due to piston, get rid of construction accuracy of manufacturing reason, can give in running piston unbalanced force because have in two, one is piston leveling system, and another is caulking gum film.Piston leveling system arranges rationally, and mounting arrangements is even, then piston each point stress equalization, can not cause drift.Caulking gum film for connecting piston and side plate, plays the effect of sealing in rubber diaphragm sealing type gas chamber, and can along with the lifting of piston scrolling.The form trait of caulking gum film is extremely important for the smooth running of piston.Once rubber membrane is formed irregularly shaped, its active force to piston is uneven, will cause piston drift.And reasonably rubber membrane state not only can not cause piston drift, also certain deviation-correcting function can be played to the drift of piston.
CN201810975U discloses a kind of caulking gum film.This technology establishes the wire cord fabric of one deck vertical direction between the orthogonal two-layer wire cord fabric in 45 degree of directions, and three layer line shape cord fabrics form " * " shape structures, become the cord fabric skeleton of rubber membrane.As illustrated in figs. ia and ib, the concrete structure of sealing rubber membrane is, it comprises inner rubber layer 1, outer rubber layer 2, for pressing the orthogonal two-layer cord fabric in 45 ° of directions between two rubber layers, i.e. internal layer cord fabric 3 and outer cord fabric 4, also arranges the reinforcement cloth 5 of one deck vertical direction between the two-layer cord fabric that described 45 ° of directions are orthogonal.This structure meets requirement substantially horizontal with appropriate tensile buckling performance, and in Vertical direction, load capacity must not the requirement of tensile buckling.But result also in the problem of substantially horizontal and Vertical direction deformation simultaneously, thus make rubber membrane easily pleating.And the pleating meeting of rubber membrane causes piston unbalance stress, cause drift phenomenon, also can be accidents caused time serious.
CN2639303Y provides a kind of high pressure dry gas holder rubber membrane " rice " character form structure adhesive plaster, the while of can being direction braiding in length and breadth, being aided with the nylon thread braiding in 45 degree of directions, left and right, making the structural type of nylon cloth adhesive plaster in " rice " shape; Or by assembly, increase the nylon canvas of one deck through broadwise interlacing in the middle of the two-layer nylon cord that namely 45 degree intersect in left and right, this adhesive plaster structural type is in " rice " font.As shown in Figure 2 a and 2 b, the concrete structure that the caulking gum film of " rice " character form structure adhesive plaster is somebody's turn to do in this employing can be, it comprises inner rubber layer 1, outer rubber layer 2, for pressing the orthogonal two-layer cord fabric in 45 ° of directions between two rubber layers, i.e. internal layer cord fabric 3 and outer cord fabric 4, also arranges the reinforcement cloth 5 of one deck level and vertical direction interlacing between the two-layer cord fabric that described 45 ° of directions are orthogonal.After the structure of adhesive plaster being implemented to the improvement of above essence, the footpath of adhesive plaster, the tensile strength in latitude direction are significantly improved, can according to different pressure requirements, the nylon cord of varying strength and nylon canvas is adopted to improve 45 ° of directions, radial direction and weft tensile strengths, thus meet the requirement of pressure, the pressure of high pressure can be born, meet the requirement of high pressure dry gas holder rubber membrane.Although adopt this kind of structure to make the tensile strength of rubber membrane obtain enhancing, rubber membrane is but restricted in ductility that is radial and broadwise, and its shape adaptability dies down, rubber membrane is thicker, harder, easy formation fold, and make piston unbalance stress, cause drift.On the other hand, rubber membrane is thickening, and the quality of unit area can increase, for low pressure operation rubber membrane more unfavorable, therefore the rubber membrane of the type is not suitable on the gas cabinet of low pressure operation.
As can be seen from above-mentioned two patented technologies, it is all consider to strengthen rubber membrane from the intensity increasing vertical direction.The deadweight of rubber membrane is the reason affecting the performance of rubber membrane own really, especially when low pressure operation (referring to below operating pressure 3kPa), its pulling force produced rubber membrane is substantially suitable to its pulling force produced with pressure medium, therefore needs to pay attention to it.But according to the technical performance of current domestic existing rubber membrane gas holder rubber membrane, the pulling force that the pulling force that its rubber membrane finished product can bear produces it under being far longer than gravity and pressure effect, therefore need not strengthen it.
Blindly rubber membrane is strengthened, add it from gravity, under low-pressure effect, because the ratio of conducting oneself with dignity shared increases, and rubber membrane itself other do not improve, the adhesive force therefore between rubber membrane and piston or side plate dies down, and then easily causes the landing phenomenon of rubber membrane, cause rubber membrane pleating, and then cause piston drift phenomenon.Domestic low pressure rubber membrane gas cabinet piston drifts about one of important reason that Here it is.
