Abstract
The utility model provides a quick-exhausting type steam coil comprising a plurality of circulation bending units. Each circulation bending unit comprises an ascending pipe, a descending pipe and a two-way bend connecting the pipes, each ascending pipe and the corresponding descending pipe form an included angle beta at the corresponding two-way bend, each two-way bend is located at the narrowest position between the two corresponding pipes, the coil is zigzag, a flow guide groove is formed in the middle of the lower end of each of the ascending pipes and the descending pipes, and the side face and the bottom of each flow guide groove are coated with hydrophobic materials. The quick-exhausting type steam coil has the advantages that a coil body is enabled to reasonably incline to the descending pipes, outflow of condensate in the steam coil can be quickened, and the problems of water hammer, freezing, pipeline breaking and the like caused by the fact that the condensate is not easy to drain are avoided; the flow guide grooves are arranged in the pipes and coated with the hydrophobic materials, adhesion of the condensate to the pipe walls can be lowered, and drain of the condensate is quickened.
Description
Technical field
The utility model belongs to steam pipe coil field, especially relates to a kind of fast row's type steam pipe coil.
Background technology
The heat exchange principle of steam pipe coil is that air carries out heat exchange by coil pipe tube wall outside and the steam of coil pipe tube wall inner side.In the design of existing steam pipe coil, heat-transfer pipe is that level is arranged, and after the steam in pipe transfers heat to air, condensation becomes water.The heat-transfer pipe that level is arranged, condensed water easily accumulates be difficult for to discharge, and causes steam pipe coil heat exchange efficiency when operation to decline, and occurs water hammer, and the rear appearance out of service phenomenon of freezing, causes coil pipe steel pipe or brass tube fracture in the time of seriously.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of fast row's type steam pipe coil, can avoid condensed water to be difficult for discharging and the problems such as the water hammer causing, icing phenomenon, pipeline breaking.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of fast row's type steam pipe coil, comprise several circulation bending units, each circulation bending unit comprises ascending tube, down pipe and the bilateral bend pipe that is connected two pipes, between two adjacent circulation bending units, also by bilateral bend pipe, connect, described ascending tube and down pipe are at bilateral pipe bent position angulation β, angle beta is 15～40 °, ascending tube and down pipe spacing are extended from narrow to wide, bilateral pipe bent position is the narrowest place between two pipes, coil pipe forms fold-line-shaped, centre position, lower end in ascending tube and down pipe is equipped with guiding gutter, the side of guiding gutter and bottom all scribble hydrophobic material, reduce the absorption of condensed water to tube wall, accelerate the flow velocity of condensed water.
Further, the cross section of described guiding gutter is rectangle, condensed water is converged to and in guiding gutter, flow to outlet.
Further, the degree of depth of described guiding gutter is 1mm, and by the Depth determination of guiding gutter, being 1mm draws through exploratory experiment repeatedly, can comply with the thickness of tube wall, can guarantee again gathering and the circulation of condensed water.
Further, described hydrophobic material is beeswax, can reduce the adhesive force of condensed water to tube wall.
Further, angle beta is 20 °, and it is to draw through exploratory experiment repeatedly that angle beta is defined as to 20 °, can guarantee that condensed water accelerates drainage speed under angle of inclination, guarantee again coil pipe alignment placement as much as possible in limited space, rationally utilize space.
Further, outside the pipe of ascending tube, be evenly equipped with some fins with the pipe outer shroud of down pipe, can reach better radiating effect.
Further, the cross sectional inner diameter of described bilateral bend pipe is greater than the internal diameter of ascending tube or down pipe, and the bottom of guiding gutter is not less than the bottom in bilateral bend pipe pipe, for in bilateral bend pipe and body joint, can guarantee the smooth outflow of condensed water, the condensed water of avoiding bilateral bend pipe to cause higher than guiding gutter bottom is detained.
Advantage and the good effect that the utlity model has are:
1. make body reasonably to down pipe, tilt, can accelerate the outflow of the condensed water in steam pipe coil, avoid condensed water to be difficult for discharging and the problems such as the water hammer causing, icing phenomenon, pipeline breaking;
2. in pipe, be provided with guiding gutter and full-filling has hydrophobic material, can reduce the adhesive force of condensed water to tube wall, accelerate the output of condensed water;
3. make steam pipe coil interior without ponding, increase heat exchange area.

Fig. 1 is the structural representation of described fast row's type steam pipe coil;
Fig. 2 is a-a face schematic diagram in Fig. 1.
In figure: 1-ascending tube; 2-down pipe; 3-bilateral bend pipe; 4-guiding gutter; 5-fin
The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Fig. 1～2, a kind of fast row's type steam pipe coil, comprise several circulation bending units, each circulation bending unit comprises ascending tube 1, down pipe 2 and is connected the bilateral bend pipe 3 of two pipes, between two adjacent circulation bending units, also by bilateral bend pipe 3, connect, ascending tube 1 and down pipe 2 are 20 ° at the bilateral bend pipe 3 angulation β of place, coil pipe forms fold-line-shaped, the cross sectional inner diameter of bilateral bend pipe 3 is not less than the internal diameter of ascending tube 1 or down pipe 2, outside the pipe of ascending tube 1, is evenly equipped with some fins 5 with the pipe outer shroud of down pipe 2.
Centre position, lower end in ascending tube 1 and down pipe 2 is equipped with guiding gutter 4, cross section is rectangle, the degree of depth is 1mm, the bottom of guiding gutter 4 is not less than the bottom in bilateral bend pipe 3 pipes, it is the position in order to join at bilateral bend pipe 3 and body, guarantee condensed water smoothly to dirty, avoid the condensed water that bilateral bend pipe 3 causes higher than guiding gutter 4 bottoms to be detained, the side of guiding gutter 4 and bottom all scribble beeswax.
Hydrophobic material can also be other wax materials or nano material etc., all can reach good hydrophobicity.Angle beta is 15～40 °, can design according to actual needs, it is preferred result that the utility model is defined as 20 ° by angle beta, to draw through exploratory experiment repeatedly, can guarantee that condensed water accelerates drainage speed under angle of inclination, guarantee again coil pipe alignment placement as much as possible in limited space, rationally utilize space.Adopt bilateral bend pipe 3 to connect two pipes, can reach the effect of removable and replaceable, can regulate the angle beta between two pipes according to actual conditions, adopt and the suitable bilateral bend pipe 3 of angle beta.
