The heater is particularly suitable for heating for various large-scale steam-water and water-water heat transfer heating networks. The heater for the heating network comprises a left pipe box and a right pipe box, as well as a pipe, plate and housing welded structure arranged between the left pipe box and the right pipe box, and a pipe bundle arranged in the pipe, plate and housing welded structure, and the heater for the heating network is characterized in that the pipe bundle is divided into three areas, which are of low-resistance areas close to the upper end and the lower end of a housing, a high-resistance area close to the central line of the pipe bundle, and a transition area arranged between the high-resistance area and the low-resistance areas respectively, and the three areas are longitudinally symmetrically arranged relative to an X axis of a horizontal central line. The heater disclosed by the utility model has high heat exchange efficiency, and can prevent pressure loss from exceeding a standard and achieve the optimal balance point of pressure drop and efficiency.
Description
Technical field
The utility model belongs to heat-exchange apparatus and manufactures field, relates to specifically the mixing heat exchangers for district heating of a kind of heat, and this heater is particularly suitable for all kinds of large-scale vapour-water, the heat supply network heating of water-heat transfer water.
Background technology
Be widely used at present steam power plant, the characteristic pipe that the heat exchanger tube of the vapour of urban district heating system--water or water--hydro-thermal net heater all adopts single light pipe or adopts single raising to conduct heat, the heat exchangers for district heating shortcoming of these two kinds of casts is obvious, 1., the heat exchangers for district heating heat transfer efficiency of light pipe type is low be in particular in:, the pressure loss little (can not take full advantage of the pressure loss of permission), the heat exchange area that identical operating mode needs is large, and the occupation of land space is relatively also large; 2., characteristic pipe heat exchangers for district heating heat transfer efficiency is high, but the pressure loss is excessive.
Summary of the invention
In order to take full advantage of the permission pressure head of heat exchangers for district heating, and improve to greatest extent heat transfer efficiency, the utility model purpose is to provide the hybrid-type heat exchangers for district heating of a kind of heat, and this heater not only heat exchange efficiency is high, and the pressure loss do not exceed standard, reach the Best Point that pressure drop and efficiency balance each other.
The utility model solves the technical scheme that its technical problem adopts:
This heat exchangers for district heating comprises left pipe box and right pipe box, be arranged on the middle tube sheet housing seam of left pipe box and right pipe box, be arranged on the tube bank of tube sheet housing seam inside, it is characterized in that: described tube bank is split into the San Ge district, it is respectively the low-resistance region near the upper and lower two ends of housing, high resistance area near the tube bank center line, be arranged on the transition region between high resistance area and low-resistance region, and described San Ge district relative level center line X-axis is arranged symmetrically with up and down.
The utlity model has following advantage and good effect:
1, the utility model utilizes the structural shape of original heat exchangers for district heating, and single heat exchanger tube form is changed into to the mixing heat exchanger tube form of heat, according to different positions, adopts multi-form heat exchanger tube.Namely at medium shunt, not smooth zone adopts the light pipe form, and favourable position adopts efficient heat conducting tube, is the characteristic pipe.Reach the flow process partition equilibrium, the flow regime at each position can reach turbulent extent.
2, the utility model takes full advantage of naturally distributing of fluid, makes the low-resistance partial discharge large, adopts light pipe, the high resistant partial discharge distributes little, adopts the characteristic pipe (to comprise the camber line pipe, the band pipe, helix tubes etc.), each several part all fully reaches turbulence state, and the pressure loss at each position is not excessive again simultaneously.
3, the utility model heat exchangers for district heating is owing to effectively improving on technique, thereby structurally, cancelled the setting of flow distributor, makes flow reach balance naturally, reduces equipment cost simultaneously.
4, the utility model has adopted the combination of light pipe and characteristic pipe, and the effective heat exchange area of heat exchangers for district heating is reduced greatly, and the drag losses of heat exchanger is down to minimum simultaneously.The advantage such as thereby the compactness rational in infrastructure, the efficiency that make heat exchangers for district heating are high, security of operation, cost are moderate.
