Abstract
The invention belongs to the technical field of waste heat boiler equipment, and relates to a perforating guide device for a waste heat boiler module finned tube, in particular to perforating guide for the waste heat boiler module finned tube. The device comprises a guide body, wherein a guide hole is formed in the center of the tail end of the guide body; and the front end of the guide body is connected with a guide head. The device is simple, compact and reasonable in structure, practical and easy; the smooth guide head can be aligned to a tube orifice of a waste heat boiler module tube plate easily; smooth perforating of the waste heat boiler module finned tube is achieved; error rates of production and mounting of the device are reduced; safe and economical perforating of a waste heat boiler module is ensured; and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of waste heat boiler module extended surface tube poling guider, be used for waste heat boiler module extended surface tube poling guiding specifically, belong to the waste heat boiler equipment technical field.
Background technology
Large-scale combustion and steam circulating power station has following advantage: the whole cycle efficieny of power plant is higher, the net efficiency height; Discharge low, little to the pollution of environment; Take up an area of and lack, water consumption is little; The automaticity height, the operations staff is less.And waste heat boiler is one of three big capital equipments of large-scale combustion and steam circulating power station, plays the important function of forming a connecting link between gas turbine and steam turbine.Its technical merit directly has influence on the generating efficiency of Combined Cycle Unit.
Waste heat boiler refers to utilize the exhaust heating working medium (water) of gas turbine, produces high temperature, the rotation of HCS driving steam turbine, drives the equipment of generator for electricity generation.Waste heat boiler requires to have stronger heat-sinking capability, generally adopts the extended surface tube heat radiation, and extended surface tube is installed in the pore between a plurality of waste heat boiler module tube sheets usually.Though the hole site that diameter is identical between waste heat boiler module tube sheet is on same straight line, but because spacing is bigger between waste heat boiler module tube sheet, general spacing has about 3 meters, tube sheet need wear that the quantity of extended surface tube is more, and the tube sheet quantity of a module has 6 ~ 8 more than, and extended surface tube is heavy and long, cause poling difficulty very in module extended surface tube poling operation, and artificial the hole is easy to occur wrong hole, thus it is impaired to make extended surface tube scrap tube sheet, and the inefficiency that wastes time and energy.Artificial this has not only influenced the cycle of waste heat boiler module making to the hole poling, and is easy to make mistakes.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of waste heat boiler module extended surface tube poling guider, adopt the guide head of slick and sly head design, be easy to aim at the pore of waste heat boiler module tube sheet, realize that boiler module extended surface tube poling is unobstructed smoothly, reduce it and produce the installation error rate, guarantee waste heat boiler module poling safety economy, improved operating efficiency.
According to technical scheme provided by the invention, waste heat boiler module extended surface tube poling guider comprises the guiding body, it is characterized in that: the tail end center of guiding body is provided with pilot hole, and guiding body front end connects guide head.
Further, the guiding body is cylinder.
Further, guide head is taper.
Further, the tapering of guide head is 60 °.
Further, the guiding body adopts nylon material to make.
Further, guide head adopts nylon material to make.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, and practicality is easily gone; Adopt the guide head of slick and sly head design, be easy to aim at the pore of waste heat boiler module tube sheet; Realize that boiler module extended surface tube poling is unobstructed smoothly, reduce it and produce the installation error rate; Guarantee waste heat boiler module poling safety economy, improved operating efficiency.

Description of reference numerals: 1-guiding body, 2-pilot hole, 3-guide head, 4-waste heat boiler module tube sheet, 5-extended surface tube.
The specific embodiment
Embodiment during following the present invention incites somebody to action by reference to the accompanying drawings is further described:
As shown in Figure 1, the present invention mainly comprises guiding body 1, and guiding body 1 is cylinder, and the tail end center of guiding body 1 is provided with pilot hole 2, and pilot hole 2 is enclosed within extended surface tube 5 front ends, is used for closely connecting extended surface tube 5.
Guiding body 1 front end connects guide head 3, and guide head 3 is taper, and the tapering of guide head 3 is 60 ° among the embodiment as shown in Figure 1.Guiding body 1 and guide head 3 adopt nylon material to make, and the guide head 3 of taper can be easy to the pore to waste heat boiler module tube sheet 4, is easy to just can pass the pore of waste heat boiler module tube sheet 4 like this, and operation is laborsaving saving time very, and efficient is very high.
Operation principle of the present invention is: shown in Fig. 2 ~ 3, when work, the present invention is connected extended surface tube 5 front ends, leads extended surface tube 5 to pass through the pore of waste heat boiler module tube sheet 4 smoothly by guide head 3.The present invention has brought convenience not only for the operation of waste heat boiler module poling, can use repeatedly simultaneously, does not increase big Material Cost, and has significantly improved the efficient of producing simultaneously.Bring out and out benefit to enterprise.
