Abstract
The utility model relates to connecting structures of hydrogen producing reforming furnaces, ammonia synthesizing reforming furnaces, methanol device reforming furnaces and the like, in particular to a furnace tube connecting device of a reforming furnace, which consists of a cannula (1), an arc porous baffle (2), a furnace tube (3) and a pigtail tube (4), and is characterized in that the cannula (1) is arranged at the upper part and inner side of the furnace tube (3), the arc porous baffle (2) is arranged at the lower part of the cannula (1) and inside the furnace tube (3), and the furnace tube (3) is connected with another furnace tube (3) through the pigtail tube (4).
Description
Technical field
The utility model relates to the syndeton of hydrogen manufacturing conversion furnace, synthetic ammonia converting, methanol device reburner etc., is specially a kind of converting furnace jockey.
Background technology
Reburner is the key equipment of device for producing hydrogen, synthetic ammonia installation, methanol device, and boiler tube and pigtail are the important component parts of reburner, and boiler tube mainly is the filling reforming catalyst, absorbs the medium generation chemical reaction that heat Gong passes through; And pigtail plays the effect that connects two boiler tubes, not only will transmit processing medium, and will effectively absorb because boiler tube at high temperature is out of shape; In actual production, our common converting furnace connected mode is single independence, the boiler tube upper end links to each other with last discharge by pigtail, down pigtail pipe links to each other with outlet manifold, this kind structure lower inlet and outlet are respectively at the equipment two ends, for guaranteeing that medium has the enough reaction time, boiler tube just must have enough length, and the length of boiler tube is the principal element that influences the reburner height, and boiler tube is long more, the reburner height is just high more, be not quite reasonable just also economically, because conversion tube is longer, swell increment is bigger simultaneously, the welding position of down pigtail pipe and boiler tube is easy to generate stress and concentrates, thereby increases the risk of weld cracking.
Summary of the invention
The utility model is just at above technical problem, and purpose is to provide a kind of reduction reburner height, but whole Transporting and the little converting furnace jockey of investment when transforming on a small scale.
Concrete technical scheme of the present utility model is as follows:
The converting furnace jockey, form by sleeve pipe, arc perforated baffle, boiler tube and pigtail, sleeve pipe is arranged on the top of boiler tube and in the inboard, the arc perforated baffle is arranged on the bottom of sleeve pipe and in boiler tube, boiler tube is connected with another root boiler tube by pigtail.
Boiler tube can be two or many connections.
Pigtail is a symmetrical structure, stay straight-run of pipe with the boiler tube junction, straight length is parallel with axis, curved left again one section arc stays straight-run of pipe after shape has a certain degree, again to the axis direction bend pipe, stay the certain-length straight length parallel with axis, bend 90 ° of arcs more to the right, stay certain straight length coaxial line vertical again, become the symmetrical structure of sealing.
The arc perforated baffle is pressed into arc, and the size of baffle plate can be blocked outlet opening fully, the close pore that drills through above it.
Technique effect of the present utility model shows: adopted the cascaded structure of boiler tube, effectively reduced the length of boiler tube, guaranteed the enough reaction time simultaneously again; Can also effectively reduce the reburner height, more reasonable economically.
