Description
Technical field
The present invention relates to a kind of petrochemical technology, especially the torch letter shoot road technology of using in a kind of Petroleum and Petrochemical Industry, specifically a kind of axial length that can carry out compensates the deformation-compensated system of the horizontal pipeline of enclosed type petroleum and petrochemical industry torch based on whirl compensator that can carry out gas-liquid separation again.
Background technique
At present, generally adopt the method for burning to carry out innocuity treatment to the toxic and harmful that can't recycle in the petroleum and petrochemical industry, so torch is the environmental protection treatment equipment of petroleum and petrochemical industry enterprise indispensability.Because the tolerance of required processing is very big, contain a large amount of corrosive liquids in the gas, and the distance between flare tip and the aerogenesis workshop is bigger, therefore, the diameter in existing torch letter shoot road is very big, all adopts the corrosion-resistant steel manufacturing, rigidity is very big, and mostly be flat auxilliary the establishing of open water greatly, the distortion of expanding with heat and contract with cold is very big, all very difficult and complicated when carrying out Stress calculation and flexible design for this reason.In order to overcome stress and the distortion that produces because of temperature variation, method commonly used at present is to adopt bend pipe compensate stress and the distortion that solves the thermal expansion generation naturally, promptly mainly is that the natural elasticity of dependence pipeline material is out of shape and absorbs thermal expansion.And because pipeline is bigger, described bend pipe will reach about 20-30 rice usually, not only expended great deal of raw materials, and occupied a large amount of soils, also need simultaneously to use a large amount of steel structure to support the contraction deformation of restrained line, bent tube section bears very easily fatigue damage of strain because of prolonged and repeated, so the design difficulty of flare line is big, cost of investment height, floor space are the difficult problems of petroleum and petrochemical industry design field greatly always.
On the other hand, whirl compensator (seeing Chinese patent ZL200610041301.4 for details) is a kind of simple in structure, compensation rate is big, the length compensation device that cost of investment is low, in underground utility, obtained at present successful application, but existing whirl compensator can only have pressure medium to use for single, and must depart from former conduit axis in using and install.Because flare line is a kind of gas-liquid two-phase flow pipeline, and pressure is less in the pipeline, the hydrops that do not allow in service stops up, otherwise is easy to have an accident, and especially must guarantee the unimpeded of pipeline in the time should being badly in need of urgent emptying.And if be installed in the top of horizontal pipeline in the existing whirl compensator using process, then can only pass through gaseous medium, liquid medium must have bigger pressure and higher flow velocity could pass through, obviously, the torch gas medium does not possess service condition, if whirl compensator is installed in the below of pipeline, then hydrops can be very fast with line clogging, and gaseous medium can't pass through, and causes security incident, therefore, the use of existing whirl compensator on flare line also is in blank, therefore, is applied to whirl compensator in the flare line as early as possible, it is big to bring into play its complementary range, and the advantage that Installed capital cost is low is the task of top priority.
Summary of the invention
The objective of the invention is at the deformation-compensated investment of existing flare line big, life-span is short, and whirl compensator can only be carried single medium, as being applied to be easy in the flare line produce blocking problem by existing method, invent a kind of axial length that can carry out and compensate the deformation-compensated system of the horizontal pipeline of enclosed type petroleum and petrochemical industry torch based on whirl compensator that can carry out gas-liquid separation again.
Technological scheme of the present invention is:
A kind of deformation-compensated system of the horizontal pipeline of enclosed type petroleum and petrochemical industry torch based on whirl compensator, it is characterized in that it comprises at least one the closed rotation compensation device that is installed on the torch horizontal pipe, described closed rotation compensation device is made up of the vertically arranged three-way pipe 2 of four whirl compensators 3 and two and last connecting tube 4 and lower communicating tube 5, two horizontal mouths of pipe that are vertically installed with three-way pipe 2 link to each other in collinear torch horizontal pipe 1 corresponding port respectively with not, two vertical mouths of pipe of each three-way pipe 2 respectively are connected with a whirl compensator 3, the whirl compensator 3 of two three-way pipe 2 upper ends linked to each other by last connecting tube 4 and forms the pipeline of air feed attitude medium circulation, and the whirl compensator 3 that is positioned at two three-way pipe 2 lower ends links to each other by lower communicating tube 5 and forms the pipeline of feed flow attitude medium circulation.
Described pipeline 1 horizontal parallel is arranged or horizontal sextant angle arranges that described angle is between the 30-90 degree.
Described lower communicating tube 5 is provided with liquid port 6.
Beneficial effect of the present invention:
The present invention should be applied to whirl compensator in the flare line in conjunction with the application success ground of three-way pipeline by the organic assembling to whirl compensator.Because the whirl compensator complementary range is long, can save a large amount of pipeline bends, reduces investment outlay and floor space.Simultaneously flare line need not to rely on the elastic strain of self material to come the absorption temperature distortion, local fatigue damage can not occur, can prolong the working life of pipeline greatly.
The present invention is by reasonable structural design, makes that the system that is made up of whirl compensator can not only be by the gaseous medium in the torch gas, and the weight of liquid medium dependence self is entered in the main pipe by whirl compensator, has function of seismic resistance simultaneously.Also can alleviate the working load of follow-up gas-liquid separator if necessary, so it can not only satisfy the compensation requirement of torch tracheae line, widen the application of whirl compensator simultaneously directly with outside the direct discharge pipe of the hydrops in the lower communicating tube.
Bucking-out system of the present invention has simple in structure, and cost is low, individual system complementary range long (can reach more than the hundreds of rice).But the limited bucking-out system of usage quantity substitutes tens even up to a hundred the compensation rates that elbow just can be finished in the past in the whole flare line.
The present invention helps the flexibility design of flare line, and it is very simple to make application calculate, and only need calculate the amount of deformation of whole pipeline and can design the corresponding compensation system.
