The novel dried tail gas waste heat step recovering system structurally comprises at least one sensible heat recovering device and at least one latent heat recovering device, wherein the sensible heat recovering device and the latent heat recovering device are in cascade connection, the sensible heat recovering device is communicated with the tail part of a drying operation device for receiving the tail gas of drying equipment and pumped heat media, and the latent heat recovering device is connected with heat users and exhaust equipment.
Description
Technical field
The present invention relates to a kind of waste heat step recovering system, especially can reclaim the novel dried tail gas waste heat step recovering system of tail gas sensible heat and latent heat in the drying operation.
Background technology
At present in China, dry power consumption accounts for 12% of industrial production total energy consumption, wherein tail gas has carried about 80% of input system total amount of heat in the fluid drying, reclaims waste heat in the dry run and whole industrial energy saving is reduced discharging has far-reaching meaning and necessity.But because the temperature lower (70～150 ℃) of drying machine tail gas, utilize traditional heat exchangers to carry out organic efficiency lower, and it is large to take up room, the heat-exchange method and the heat-exchanger rig that lack low-cost high-efficiency, present tail gas to the industrial production drying machine carries out waste heat recovery and does not obtain yet obvious progress, and especially the latent heat of vaporization in the dried tail gas is not effectively reclaimed.
Summary of the invention
Purpose of the present invention is exactly in order to address the above problem, and a kind of novel dried tail gas waste heat step recovering system is provided, and it can effectively reclaim dried tail gas waste heat, not only can effectively reclaim the tail gas sensible heat, can also reclaim the latent heat of vaporization of steam in the tail gas.
For achieving the above object, the present invention adopts following technical scheme:
A kind of novel dried tail gas waste heat step recovering system, it comprises at least one heat recovering device and at least one recovery of latent heat device, both series connection; Wherein heat recovering device is connected with drying operation device afterbody, receives the tail gas of drying equipment and the thermal medium that pumps into; The recovery of latent heat device then is connected with emptying equipment with hot user.
Described heat recovering device is Oscillatory flow heat pipe exchanger.
Described recovery of latent heat device is source pump.
The present invention arranges an Oscillatory flow heat pipe exchanger at the afterbody of drying operation, and working medium transfers to condensation segment with heat by bringing-up section by boiler in the heat exchanger, and recovery waste heat is used for heating the functions such as new wind.With the Oscillatory flow heat pipe exchanger heat-shift after dried tail gas in still contain a large amount of water vapour latent heats of vaporization, rear portion at Oscillatory flow heat pipe exchanger arranges evaporator with heat pump, namely in the heat recovery system of the second level, source pump is set, the latent heat of vaporization in effective absorption dehydration tail gas, recovery waste heat is realized energy-saving and emission-reduction to greatest extent.
The invention has the advantages that, the Oscillatory flow heat pipe exchanger thermal efficiency is high, and all temperature characteristics is good, and the heat transfer direction is reversible, volume is little, thermal response rapidly but also have easy for installation, easy to maintenance, long service life, drag losses little, advance the air draft runner and the advantage such as be convenient to separate, do not leak through with each other; Source pump efficient aspect absorption steam gasification latent heat is high, and energy consumption is low.
Description of drawings
Fig. 1 utilizes Oscillatory flow heat pipe exchanger and source pump step to reclaim the flow chart of dried tail gas waste heat technique.
Wherein, 1. Oscillatory flow heat pipe exchanger, 2. source pump.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, it comprises an Oscillatory flow heat pipe exchanger 1 and a source pump 2, both cascades; Wherein Oscillatory flow heat pipe exchanger 1 is connected with drying operation device afterbody, receives the tail gas of drying equipment and the thermal medium (air or water) that pumps into; 2 of source pump are connected with emptying equipment with hot user.
The course of work of the present invention is: the tail gas from drying machine at first enters Oscillatory flow heat pipe exchanger 1, and the heat exchanger bringing-up section rear working medium self-pulsating that is heated conducts heat to condensation segment, makes the air that pumps into or the temperature increase of water; Then dried tail gas enters secondary heat exchanger---source pump 2, and heat pump is transferred to air or water with heat after reclaiming a large amount of latent heats of vaporization, then supplies with hot user, and tail gas is then emptying.
