Description

A kind of Direct Air-Cooled tower residual heat using device
Technical field
The invention belongs to heat energy recovery equipment technical field, it is adaptable to Direct Air-Cooled formula generating set, be specifically related to one Direct Air-Cooled tower residual heat using device.
Background technology
Along with the day by day deficient of whole world water resource and the great attention to environmental protection problem.Owing to needs consume a large amount of Environment is also caused significant negative impact by water resource, and tradition thermoelectricity water chiller has been faced with severe challenge.In recent years, in order to slow Solving this problem, China puts into operation in the northwestern of rich coal poor-water substantial amounts of Direct Air-Cooled formula generating set, effectively alleviates The situation of the local generation deficiency caused due to water resources shortage, social benefit is notable.
So-called Direct Air-Cooled formula generating set, is the cooling medium using surrounding air as turbine discharge.With working medium Water is compared, and air has the advantages such as specific heat capacity is little, heat conductivity is little, and therefore direct air cooled condenser typically uses finned tube to tie Structure, turbine discharge carries out condensation heat in finned tube, and the condensation water of formation is directly entered condensate tank, quilt outer with finned tube The air generation convection heat transfer' heat-transfer by convection of blower fan pressurization.But, under current reality, Air-Cooling Island outlet hot-air can reach 40 DEG C~50 DEG C, this hot-air is the most just directly discharged into air, and this had both wasted substantial amounts of heat energy, again environment was created thermal pollution.
Summary of the invention
For technical problem present in above-mentioned prior art, the invention provides a kind of Direct Air-Cooled tower UTILIZATION OF VESIDUAL HEAT IN dress Put, the efficient utilization to direct air cooled condenser outlet hot-air, it is achieved energy-efficient purpose.In conjunction with Figure of description, this The technical scheme of invention is as follows:
A kind of Direct Air-Cooled tower residual heat using device, is made up of heat exchanger, water pipe and connection pipeline, and described UTILIZATION OF VESIDUAL HEAT IN fills Put main body linearly attachment structure, connected pipeline, heat exchanger, water pipe and the connection of drainage connecting pipe road by water inlet successively and form;
Connect, in described water inlet, the water inlet offered on pipeline, dock with the low-temperature heat source entrance of heat exchanger, be used for inputting Water at low temperature;
The bleeding point installed outside heat exchanger, docks with the high temperature heat source entrance of heat exchanger, is used for inputting high temperature air;
The air vent offered outside heat exchanger, exports with the low-temperature heat source of heat exchanger and docks, be used for exporting Cryogenic air;
High temperature heat source outlet and the water pipe abutting joint of heat exchanger, water pipe end is connected with drainage connecting pipe road, for defeated Go out high-temperature water.
A kind of Direct Air-Cooled tower residual heat using device, wherein, connects in the outside wall surface of pipeline in described water inlet, fixed installation There is handle, in order to docked by Pipeline lift fixing with air cooling tower.
Compared with prior art, the beneficial effects of the present invention is:
1, a kind of Direct Air-Cooled tower residual heat using device of the present invention, using direct air cooled condenser export hot-air as Heat exchanger thermal source and low-temperature receiver water carry out heat exchange, and produced hot water can be used for for user, it is achieved the recycling to heat energy;
2, a kind of Direct Air-Cooled tower residual heat using device of the present invention, is introduced directly into a part of condenser tempering air Air preheater, makes the air themperature of air preheater entrance improve about 20~25K, thus realizes energy-conservation and alleviate low temperature The purpose of corrosion.

Detailed description of the invention
In order to further illustrate technical scheme, in conjunction with Figure of description, the detailed description of the invention of the present invention is such as Under.
As depicted in figs. 1 and 2, the invention discloses a kind of Direct Air-Cooled tower residual heat using device, described UTILIZATION OF VESIDUAL HEAT IN fills Put linearly structure, mainly, connected pipeline, heat exchanger, water pipe and the connection of drainage connecting pipe road by water inlet successively and form.
Described water inlet connects pipeline and is positioned at whole device head end, and water inlet connects on the upper outer wall face of pipeline, fixed installation There is handle 2, in order to docked by Pipeline lift fixing with air cooling tower.On the lower outer wall that water inlet connects pipeline, offer There is water inlet 4, for low-temperature cold water being introduced whole residual heat using device.
As shown in figures 1 and 3, heat exchanger 1 is installed on and connects pipe downstream into water, and by heat exchanger fixing device 9 with The bleeding point 5 in outside connects.Heat exchanger 1 offers four mouths, respectively heat exchanger low-temperature heat source entrance 8, heat exchanger altogether High temperature heat source entrance 10, heat exchanger low-temperature heat source outlet 11 and the outlet of heat exchanger high temperature heat source.Wherein, heat exchanger high temperature heat source Entrance 10 and bleeding point 5 abutting joint being positioned at outside heat exchanger, by bleeding point 5 using air cooling tower waste heat as heat exchanger high temperature Thermal source introduces heat exchanger;Heat exchanger low-temperature heat source entrance 8 docks, using cold water as heat exchange with the water inlet 4 in water inlet connecting tube Device low-temperature heat source introduces heat exchanger, preheats with the air cooling tower as high temperature heat source and does heat exchange, output cold air and warm water.Heat exchange Device low-temperature heat source outlet 11 and air vent 3 abutting joint being opened in outside heat exchanger, be expelled to the Cryogenic air after heat exchange External environment;The outlet of heat exchanger warm water and water pipe 6 abutting joint in downstream, described water pipe 6 is two, is connected to heat exchanger side by side high Temperature-heat-source exit.
The downstream of described water pipe 6 connects drainage connecting pipe road, and the warm water after heat exchange flows through drainage connecting pipe through water pipe 6, Discharge outlet 7 through drainage connecting pipe end is discharged eventually, to realize recycling.
Work process and the principle of the present invention are as follows:
Normal temperature air significantly promotes through direct air cooling system temperature, through air cooling tower discharge air heat source through bleeding point It is introduced to the residual heat using device of the present invention, and as the air heat source passage of high temperature heat source entrance heat exchanger, meanwhile, cold water leads to Cross water inlet pipe and introduce apparatus of the present invention, flow through heat exchanger as low-temperature heat source, carry out heat exchange with hot-air, obtain from hot-air Heat makes cold water temperature promote, and is flowed out by the outlet of heat exchanger warm water subsequently, flows through water pipe and flows out in addition profit again from discharge outlet With.
