Description
Technical field
The invention belongs to industrial energy saving technical field, in particular to the adjusting shrinkage cavity device of a kind of hydraulic-driven is used for gas
The flow and flow deviation between multiple parallel pipelines are adjusted on body or Dual-Phrase Distribution of Gas olid material conveying pipe.
Background technique
Pipeline gas or Dual-Phrase Distribution of Gas olid material are often used in industrial production, often can also use multiple parallel pipes
Road conveying, therefore to adjust flow deviation there are commonly regulating valve or controllable registers, the disadvantage is that flow field change is big, restriction loss
Greatly；It is to adjust shrinkage cavity there are also a kind of mode, current existing adjusting shrinkage cavity is all made of the similar the same screw drive structure of valve,
This structure on liquid, there is no problem, when being used in gas or Dual-Phrase Distribution of Gas olid material and conveying, due to moisture and oxygen
Effect is easy to happen corrosion, and solid particle is also easy blocking rotary part, is substantially difficult to adjust again after a period of use.Example
The adjusting shrinkage cavity used such as coal-fired station.The mode of coal-fired station's coal combustion mostly uses greatly coal dust firing method,
Raw coal is sent into coal pulverizer by which by feeder to be preheated, is ground, by the coal for meeting fineness requirement after separator
Powder and First air Dual-Phrase Distribution of Gas olid pass through more primary wind pipes feeding hearth combustions.Due to the position of coal pulverizer and boiler-burner
Relationship is set, the distance of coal pulverizer to each coal burner is not identical, elbow quantity also has difference.So that each primary wind pipe length
There is very large deviation with resistance, causes the fuel quantity deviation into each coal burner very big.Therefore burning in furnace is influenced whether
With the uniformity of temperature, it will cause and wash away uneven water-cooling wall, boiler coke, boiler expansion, the blocking of primary wind and powder pipeline and two sides
The problems such as smoke temperature and big Temperature Deviation.In view of the above problems, relatively effective precautionary measures are to install to adjust in primary wind pipe
Shrinkage cavity is saved, First air leveling test is carried out during unit regulation or after major overhaul, the wind speed in each primary wind pipe is inclined
Difference is adjusted within prescribed limit.
The method that First air leveling uses is mainly " power station coal pulverizer and pulverized coal preparation system performance test " DLT467-2004
The method of interior 6.1.3 item " adjusts shrinkage cavity or the air door on primary air piping, so that each primary air piping maximum quantity of wind is opposite in the cold state
Deviation is not more than ± 5%." key of test is accurate measurement primary air piping maximum quantity of wind, calculate relative deviation.
Currently, the adjusting shrinkage cavity used is all made of the screw drive of similar manually-operated gate, due to the work of vapor and air
With being easy to corrode, coal dust can also block rotary part, therefore the shrinkage cavity structure newly installed can use one with normal regulating
Shrinkage cavity screw rod corrosion blocking can not just be adjusted again after the section time.
