The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As shown in drawings: a kind of combined method that is used for the coil pipe unit of transverse flow enclosed cooling tower, its process is: at first, the entrance point 7 of coil pipe unit and the port of export 1 are all made belled tube-end and are added the nut form, respectively in order to be connected with outlet vertical headers 10 with the import vertical headers 11 of transverse flow enclosed cooling tower; Adjacent entrance point 7 is one section bellows 8, the adjacent port of export 1 also is one section bellows 2, in order to adjust the position of the entrance point 7 and the port of export 1, the other end at bellows 8 connects h shape conversion head 9 then, the other end at bellows 2 connects h shape conversion head 3, between h shape conversion head 9 and h shape conversion head 3, connect the coiled pipe row of forming by a plurality of straight tubes 4 and a plurality of U-shaped pipe 6, constitute two-way up and down in parallel and become stagger arrangement etc. flow process and etc. the coil pipe unit of flow resistance, and each straight tube in the coil pipe 4 is fixed by certain spacing with spacer 5.
This structure adopts being threaded of coil pipe unit and collector 11 and collector 10, install change convenient, and under the condition of the outer windage permission of pipe, (B when minimum accomplishes that straight tube centre-to-centre spacing L is the triangular arrangement of external diameter of pipe D twice
Min=1.732D), still can import and export between joint and adjacent disc pipe unit import and export joint and leave enough spanner working spaces at coil pipe unit, at this moment coil pipe unit is imported and exported the minimum centers-distance L of joint and adjacent disc pipe unit import and export joint
MinShould be 2B
Min, therefore accomplish the compact conformation (see figure 2).One section bellows piece 8 is arranged behind the import pipeline section 7, and one section bellows piece 2 arranged behind the outlet pipe section 1, fine-tuning angle and length are passed through under the fixing condition of spacer 5 and tower body coil pipe unit, and coil pipe unit is imported and exported joint and docked and tighten very convenient with the screw thread of collector 11 and collector 10.
The entrance point 7 of coil pipe unit is positioned at the air side of upper strata coil pipe, and the port of export 1 is positioned at the inlet side of lower floor's coil pipe, makes coil pipe unit and horizontal plane form a low-angle α who has a down dip to outlet side from inlet side and (sees that Fig. 2～Fig. 4), this angle is recommended as 4～7 °.So just guaranteed the highest point of entrance point 7 at coil pipe unit, the port of export 1 is at the lowest part of coil pipe unit, and from entrance point 7 always descending to the port of export 1 along journey, can be when blank pipe fills working medium thereby convenient from the abundant exhaust of top vent valve of inlet header 11, because the existence of inner air tube will reduce the radiating effect of intraductal working medium; Also make things convenient for simultaneously when stopping using bottom blow valve emptying intraductal working medium, in order to avoid bursting by freezing coil pipe in the winter time from outlet header 10.
