Description
Technical field
The present invention relates to the treatment facility of coal dust, particularly a kind of heatproof high pressure medium containing dust pressure obtaning device.
Background technology
At present, in pressure measurement technology, all there is not the different techniques problem in single-phase or two media that mix mutually in the process of its pressure for gas-liquid.But for medium containing dust, like the pressure survey on coal dust pneumatic carrier road, often because of the leakage of coal dust pressure pipe plug plug takes place, especially this problem is just more outstanding under the hyperbaric environment.
The main dual mode that adopts carries out in the technology of existing use: a kind of is to adopt enlarged tube depositing dust principle; Add the structure that steam or pressurized air purge simultaneously; But this apparatus structure more complicated; That especially adopts steam blowing also needs insulation, and withstand voltage limited, effect is also undesirable in actual the use.Another kind is to adopt the barrier film of materials such as rubber or plastics to isolate medium and measuring system; But this systematic survey requires full of liquid, and temperature is not high, and the barrier film easy ageing; Influence measuring accuracy, in addition owing to can not under high pressure use by the influence of barrier film material.To above technical matters, once the someone proposed a kind of easy medium containing dust pressure obtaning device, but this structure employing is threaded, and under high temperature, high pressure, exists poor sealing to cause technical matterss such as leakage equally.
Summary of the invention
The present invention is directed to the deficiency of existing pressure obtaning device; A kind of heatproof high pressure medium containing dust pressure obtaning device is provided, and the pressure signal that can be used for high temperature, high pressure medium containing dust takes out, and has favorable mechanical performance and sealing property; And applicability is wide; Simple in structure, and can be used for high-pressure medium and certain high temperature (about 300 ℃), thus solved the taking-up difficult problem of HTHP medium containing dust pressure in the industry.
Technical scheme of the present invention is following:
A kind of heatproof high pressure medium containing dust pressure obtaning device; Be installed on the medium containing dust pipeline; It is characterized in that: comprise strainer tube, strainer tube overcoat and pressure adapter, strainer tube is connected in the medium containing dust pipeline, and the outer cover of strainer tube is connected to the strainer tube overcoat; Strainer tube puts outward and offers perforation, and pressure is taken over through perforation and is connected with the strainer tube overcoat is vertical; The outside of the end that said pressure adapter is connected with the strainer tube overcoat is provided with the pressure-bearing circle, is used to bear high pressure, and it is outside that the pressure-bearing circle is close to the strainer tube overcoat, and secure is passed through at pressure-bearing circle two ends.
Said strainer tube, strainer tube overcoat, pressure-bearing circle are all coaxial, and the axis direction perpendicular to strainer tube, strainer tube overcoat, pressure-bearing circle is taken in pressure.Said strainer tube overcoat is cylindrical, and the gas permeation strainer tube that is used for the medium containing dust pipeline passes strainer tube and covers into the pressure adapter outward.
Said pressure is taken over and is vertically passed pressure-bearing circle, strainer tube overcoat successively.
Adopt the O RunddichtringO to seal between said pressure-bearing circle and the strainer tube overcoat.
Said flange is a concave surface band neck socket welding flange.
Adopt the O RunddichtringO to seal between said pressure-bearing circle and the flange.
Adopt welding or viscose glue bonding between said strainer tube and the strainer tube overcoat.
Simultaneously, strainer tube also adopts the sintering metal porosint to make, and can prevent effectively that dust from leaking in the pressure pipeline.
Said strainer tube overcoat is that a pipe linear element is enclosed within the strainer tube outside, is convenient in the medium containing dust pipeline gas permeation strainer tube and passes strainer tube and cover into pressure outward and take over.
Beneficial effect of the present invention is following:
The present invention adopts the sintering metal porosint as strainer tube, has favorable mechanical and strainability; Adopt pressure-bearing circle and female flange to fix, can be used for the medium containing dust pressure under high temperature, the high pressure; Adopt the O RunddichtringO to seal, can accomplish good sealing effectiveness, situation such as leakage can not occur, can effectively improve the accuracy of pressure; Applicability of the present invention is wide, and is simple in structure, and can be used for high-pressure medium and certain high temperature (about 300 ℃, actual temp is looked the O type circle material that is adopted and decided), thereby solved the taking-up difficult problem of HTHP medium containing dust pressure in the industry.
