Abstract
A pressure-tapping measuring device belongs to a matching device in a blast furnace pulverized coal injection technology. The pressure-tapping measuring device comprises a pressure-tapping pipe, wherein one end of the pressure-tapping pipe is communicated with a pulverized coal blowing conveying pipeline. The pressure-tapping measuring device is characterized in that a filter cylinder is sleeved inside the pressure-tapping pipe; the other end of the pressure-tapping pipe is movably communicated with a connecting pipe; and the other end of the connecting pipe is connected with a connecting valve and a pressure gauge in order. During operation of a pulverized coal system, part of pulverized coal and gas simultaneously enter the pressure-tapping pipe, and after the pulverized coal and the gas are filtered by the filter cylinder, the pulverized coal is collected, and the gas is measured by the pressure gauge. The pressure-tapping measuring device allows the pulverized coal and the gas to be separated, enables the measuring precision to be improved, helps to minimize wearing of an instrument by the pulverized coal, enables the service life of the instrument to be prolonged, and is convenient to clean and replace.
Description
Technical field
The utility model relates to the corollary apparatus in a kind of pulverized coal injection powder craft, particularly a kind of pressure measurement mechanism.
Background technology
In the pulverized coal injection powder craft, easily cause whole injection system running unstable, inhomogeneous because of the fluctuation of the correlation parameters such as the weight of coal dust, pressure, temperature, even cause coal powder injection out of service, wherein for solving the impact of coal dust pressure, generally be to install tensimeter additional in the tank body, pipeline at coal injection system, in order in time carry out pressure survey, and existing pipeline pressure-measurement measurement mechanism is directly at pipeline upper shed setting pressure table.Ducted coal dust and gas enter tensimeter simultaneously, easily stop up, the wearing and tearing instrument, affect accuracy of measurement and the serviceable life of instrument.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned weak point of prior art, and provides a kind of measuring accuracy high, prolongs the pressure measurement mechanism in Instrument use life-span.
The purpose of this utility model is achieved in that the pressure measurement mechanism comprises that an end is communicated with the pressure pipe of breeze blowing conveyance conduit, it is characterized in that being set with in the pressure pipe cartridge filter, the movable connecting pipe that is communicated with of the other end of pressure pipe, the other end of connecting pipe connects valve, tensimeter successively.
The utility model is owing to adopting above architecture advances, and coal injection system is in service, and part coal dust and gas enter pressure pipe simultaneously, and after filtering through filter cylinder, coal dust is collected, and gas is measured by tensimeter.Coal dust is separated with gas, improved measuring accuracy, reduced the wearing and tearing of coal dust to instrument, prolonged the Instrument use life-span, cleaning, replacing are conveniently.
