Description
Technical field
The utility model relates to a kind of anti-block apparatus, is particularly suitable for but is not limited only to the pressure pipe anti-block apparatus of yellow phosphorus high-temperature dust removal system.
Background technology
In the industrial production of yellow phosphorus, the pressure pressure technique of yellow phosphorus high-temperature dust removal system faces along with dust constantly increases, the problem of pressure guiding pipe will be blocked, for the existing universal way of this problem be adopt stop into the method for people labor cleaning, but along with pressure pipeline blockage problem occurrence frequency increases, adopt the method to increase down time, production efficiency is reduced, be also unfavorable for safety production monitoring simultaneously.For the medium comparatively complexity of similar pressure environment, often have dust comparatively large, easy precipitation, the easily problem such as condensation, tar content great Yi blocking, need the anti-block apparatus that a kind of structure is simple, easy to operate, blocking-proof result is obvious and maintenance cost is cheap.
Utility model content
The utility model provides a kind of pressure pipe anti-block apparatus, and the structure adopting steam blowback and mechanical block clearing to combine, can reduce the possibility of pressure pipe inner surface fouling, make pressure sensor group long-time steady operation simultaneously, thus improves factory work efficiency.
The utility model provides a kind of pressure pipe anti-block apparatus, and it comprises pipe-blocking-proof, ball valve, the first valve arrangement, the second valve arrangement, insulation construction, cleansing pin and steam anti-blowpipe, its syndeton is pipe-blocking-proof and medium circulation tube radial communication, the strip shape gob of pipe-blocking-proof is located at tube wall side, vertical pressure pipe is located in pipe-blocking-proof, cleansing pin is fixed in vertical pressure pipe by ball valve, steam anti-blowpipe is by the first valve arrangement and horizontal segment pressure pipe radial communication, horizontal pressure pipe is connected with pressure sensor group by the second valve arrangement, pressure pipe blocking main cause is dust or waste liquid dust mixture condensation in pressure pipe of larger particles, adopt above device on pressure pipe, add the structure of steam blowback and mechanical block clearing, effectively can remove and block and produce anti-blocking effect, first ball valve is opened when pressure pipe blocks, use, by the cleansing pin of ball valve, machinery dredging is carried out to vertical pressure pipe, then ball valve is closed, close the second valve arrangement again, open the first valve arrangement, now high temperature and high pressure steam/inert gas enters horizontal pressure pipe by steam anti-blowpipe and carries out blowback dredging with vertical pressure pipe to blocking place, finally close the first valve arrangement, open the second valve arrangement.
Optionally, the first valve arrangement and the second valve arrangement can select needle valve, and it has easy installation and removal, it is fastening to connect, be conducive to the advantage such as fire prevention, explosion-proof and voltage endurance capability is high, favorable sealing property.
Further, the strip shape gob of pipe-blocking-proof adopts oval structure, and add the usable floor area of strip shape gob than traditional structure, pressure area also increases thereupon, make the dust of larger particles or waste liquid dust mixture not easily be attached to air hatch, thus reduce pressure pipe inner surface fouling possibility.
On this basis, the opening direction of the strip shape gob of pipe-blocking-proof is consistent with medium circulating direction in medium circulation tube, is conducive to reducing the possibility that dust in medium or waste liquid dust mixture are piled up at strip shape gob place.
Further, after second valve arrangement is located at steam anti-blowpipe and horizontal segment pressure pipe connected node, when the first valve arrangement open pass into high temperature and high pressure steam/inert gas reverse blowing disposal is carried out to pressure pipe time, close the second valve arrangement and high temperature and high pressure steam/inert gas can be stoped to flow into pressure sensor group.
Further, by the insulation construction be provided with at pipe-blocking-proof outer surface, significantly can reduce the medium condenses speed entering pressure pipe, thus reduction there are crystal class or other impurity separate out and cause the possibility of fouling.
Pressure pipe anti-block apparatus structure of the present utility model is simple, easy to operate, effectively can solve such as yellow phosphorus high-temperature dust removal system but be not limited only to this blockage problem, and obviously maintenance cost can be reduced in industrial application, be specially adapted to the pressure Region Mediums such as yellow phosphorus high-temperature dust removal system, coal liquifaction and coal gas filtration system more complicated, dust is larger, exist and easily separate out, easy condensation, the large susceptible to plugging operating mode field of tar content.
Below in conjunction with accompanying drawing, the utility model is further illustrated, realize to enable those skilled in the art and utilize the utility model.
