Abstract
Provided is an evaporator for petroleum and natural gas medium-and-low-grade waste heat power generation. The evaporator for petroleum and natural gas medium-and-low-grade waste heat power generation comprises an evaporator body, wherein a plurality of evaporating pipes which are arranged in a parallel mode penetrate through the front end and the rear end of the evaporator body, each evaporating pipe is a conical pipe, an organic working medium inlet is formed in the end, with the smaller diameter, of each evaporating pipe, an organic working medium outlet is formed in the end, with the larger diameter, of each evaporating pipe, and a waste heat water inlet and a waste heat water outlet are formed in the front end and the rear end of the evaporator body respectively, and are formed in a gap between every two adjacent evaporating pipes which are arranged. According to the evaporator, due to the fact that the conical evaporating pipes are adopted, the pressure of organic working media is high in the organic working medium inlets, the pressure of the organic working media is low in the organic working medium outlets, and vaporization can easily happen; due to the facts that the same waste heat water inlet ends arranged in the gaps between the evaporating pipes are small in sectional area and high in flow velocity, and the same waste heat water outlet ends arranged in the gaps between the evaporating pipes are large in sectional area and low in flow velocity, heat exchange strength of the evaporating pipes are consistent in the whole heat exchange process, and heat exchange efficiency can be improved.
Description
Technical field
The utility model relates to waste heat power generation equipment field, is specifically related to for petroleum gas low grade residual heat generating evaporimeter.
Background technology
Evaporimeter is the important component part of device for generating power by waste heat, burden heat exchange makes organic working medium produce steam, during in petroleum gas, low grade residual heat generates electricity, waste heat supply temperature is low, and the heat exchange efficiency of evaporimeter seems particularly important with the balanced of heat transfer intensity, and the flow velocity of the remaining hot water of common tubular evaparator is constant, entrance point temperature at remaining hot water is higher, the temperature of outlet is lower, makes the heat transfer intensity difference of the front-end and back-end of evaporimeter, affects heat exchange efficiency.
Summary of the invention
In order to address the above problem, the utility model is provided for low grade residual heat generating evaporimeter in petroleum gas, and by the flow velocity of remaining hot water is changed, the pressure of organic working medium changes simultaneously, and balanced heat transfer intensity improves heat exchange efficiency.
The technical solution of the utility model is: low grade residual heat generating evaporimeter in petroleum gas, comprise evaporator body, some evaporation tubes that are arranged in parallel run through the front and back end of evaporator body, evaporation tube is a conical pipe, one end that diameter is little is organic working medium import, one end that diameter is large is organic working medium outlet, in the evaporation tube space of arranging, and the front and back end of evaporator body have surplus heat respectively water inlet and remaining hot water outlet.
In such scheme, organic working medium entrance point and rear end, the organic working medium port of export and the remaining hot water import front end in evaporator body of remaining hot water outlet in evaporator body.
In such scheme, the outer wall of evaporation tube extends continuous triangle projection, and there is fillet on the top of triangle projection.
The utlity model has following beneficial effect: by adopting the evaporation tube of taper, organic working medium pressure when import is higher, outlet pressure is lower, easily produce vaporization, the sectional area of the remaining hot water entrance point that space between evaporation tube is the same is little, and flow velocity is high, the sectional area of the remaining hot water port of export is large, flow velocity is low, makes evaporation tube consistent at whole heat transfer process heat transfer intensity, is conducive to improve heat exchange efficiency.
accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is cross-sectional view of the present utility model.
In figure 1, organic working medium outlet; 2, remaining hot water import; 3, evaporation tube; 4, evaporator body; 5, remaining hot water outlet; 6, organic working medium import; 7, triangle projection; 8, fillet.
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Fig. 2, low grade residual heat generating evaporimeter in petroleum gas, comprise evaporator body 4, some evaporation tubes that are arranged in parallel 3 run through the front and back end of evaporator body 4, evaporation tube 3 is a conical pipe, one end that diameter is little is organic working medium import 6, one end that diameter is large is organic working medium outlet 1, evaporation tube 3 spaces of arranging, water inlet 2 and the remaining hot water outlet 5 that has surplus heat respectively of the front and back end of evaporator body 4, organic working medium pressure when import is higher, outlet pressure is lower, easily produce vaporization, the sectional area of remaining hot water import 2 ends that space between evaporation tube 3 is the same is little, flow velocity is high, the sectional area that remaining hot water exports 5 ends is large, flow velocity is low, make evaporation tube 3 consistent at whole heat transfer process heat transfer intensity, be conducive to improve heat exchange efficiency.
In such scheme, organic working medium import 6 ends and the rear end of remaining hot water outlet 5 in evaporator body 4, organic working medium exports 1 end and the front end of remaining hot water import 2 in evaporator body 4.
In such scheme, the outer wall of evaporation tube 3 extends continuous triangle projection 7, and there is fillet 8 on the top of triangle projection 7, increases heat exchange area, and fillet prevents corrosion and turbulent generation.
