Description
The present invention relates to a kind of constructive method and device thereof of high-efficient vaporized heat supply system.
Known indirect steam heating system (is called for short " prevailing system ".) by thermal source (A), steam transmitting pipe net (B), with hot equipment (can be a plurality of equipment) (C), drain valve (every with hot equipment must adapted) (D), return pipe net (E) and coagulation hydroenergy backwater station (F) wait each one to constitute.Also have behind drain valve and to be about to that condensate water discharges on the spot.Formation such as Fig. 1 of prevailing system show.The heat energy utilization rate of this system is very low.The key equipment that constitutes prevailing system is a drain valve, and can system also be drain valve with the key equipment of higher heat energy utilization rate operation.As everyone knows, the drain valve great majority that China uses now cause a large amount of vapour to lose by drain valve because many former thereby poor quality such as technical, process aspect and detection means are used it for system.In order to improve the heat energy utilization rate of prevailing system, professional and technical personnel both domestic and external nearly all the performance of improving drain valve as research direction.It is worthy of note: prevailing system promptly has been to use the high-quality drain valve, and the raising of its heat energy utilization rate also is limited.Because the constitution theory of prevailing system is complete inadequately.Facts have proved: every is all disposed drain valve with hot equipment, make the condensate water in the return pipe net be the moving state of stream-liquid two-phase flow, particularly have under the situation that a large amount of vapour bleed, condensate water can not be reclaimed effectively, also be difficult to utilize the low-grade energy steam (flash steam or secondary vapour) in the return pipe net.
In the last few years, in states such as Japan, the U.S. so-called condensate water conveyer and high-temperature condensate water recovery unit have appearred successively at first, also introducing or developed similar product with reference to foreign technology in China subsequently, have certain energy-saving effect, is up-to-date energy-conserving product.But these products only are the problems of carrying without condensate pump that solves under the situation that condensate water has been assembled, and do not have the ability that improves with hot equipment heat energy utilization rate and recovered steam condensate water.Thereby it can not increase substantially the heat energy utilization rate of prevailing system.Because these products do not relate to the constructive method of prevailing system, still bear the block steam and drain water effect by drain valve.
It is considered herein that, increase substantially the heat energy utilization rate of steam heating system, particularly use the heat energy utilization rate of hot equipment, must propose a kind of new system's constructive method and can realize to form new system form.
The present invention's purpose is to provide a kind of constructive method and device thereof of high-efficient vaporized heat supply system, the drain valve that the cancellation prevailing system disposes with hot equipment, carry out each centralized drainage with hot equipment, guarantee vapour return pipe net that do not bleed, whole recovered steam condensate water, heat energy utilization rate with hot equipment is brought up to more than 90%, thereby system's total heat energy utilization rate is greatly improved.
System that the present invention relates to (hereinafter to be referred as " new system ") and device rely on following principle and set up;
A. accurate press all that principle refers to the useful hot equipment that equates with steam pressure should keep basically identical with steam pressure, reach with each point pressure in the vapour system and be the equal pressure condition of standard, carbonated drink is separated in finishing in the hot equipment;
B. the centralized drainage principle refers to cancel the drain valve that is disposed in the prevailing system with hot equipment, replaces the centralized drainage that a high self-draining arrangement (H) of reliability is finished numerous equipment.Being provided with double-deck big thickness water seal layer in this device (H) leaks to stop a vapour;
C. the hot-well depression principle refers to that condensate water obtains than just entering return pipe net behind the low temperature gap (being degree of supercooling) of saturation temperature under the terminal back pressure of return pipe net through ad hoc subcooler.Adjusting to condensate undercooling can be realized by electronic or pneumatic or self-operated type regulating system;
D. the static pressure conveying principle refers to that the conveying of condensate water relies on owned pressure (near with vapour intrasystem steam pressure.) realize, and do not consume initial steam;
E. single liquid phase flow principles refers to obtain degree of supercooling before condensate water enters return pipe net, enters no longer to be the moving state of stream-liquid two-phase flow behind the return pipe net, and is that single liquid phase flows.Flash steam (or secondary vapour) no longer produces thus, the application problem of low-grade energy steam and be difficult to utilize and the heat-energy losses that causes has also no longer existed.
New system such as Fig. 2 of relying on above-mentioned principle to constitute show.
Examination compares Fig. 2 and Fig. 1, is not difficult to find, new system will include a unified research range in portions such as the interior system that hot equipment constituted, hydrophobic link, return pipe nets.Do not re-use drain valve with hot equipment and carry out hydrophobicly, and adopted self-draining arrangement (H) to realize centralized drainage.Like this, all enter initial steam with hot system and do not discharge entrained latent heat and just can not change return pipe net over to and participate in the working medium circulation.Condensate water has the pressure near initial steam simultaneously, can successfully go to condensate water and collect ground and have no way of loss.Flash steam (or secondary vapour) no longer exists and produces.It is calculated that condensate water is to obtain heat energy that degree of supercooling loses to account for and infeed with 5% of system's total heat energy in the hot equipment.This is the link of the unique loss heat energy of new system constitution theory.Other radiation losses as equipment and internal pipeline can guarantee to be lower than 4% by designing and constructing, and this does not belong to the drawback on the new system constitution theory.
The device that the present invention relates to (being self-draining arrangement H) is the key equipment that can new system successful.Automatic drain valve in this device (X) can be Pneumatic valve, electrically-controlled valve or mechanically controlled valve.Condensate water can adopt water-cooled or air-cooled the realization for obtaining degree of supercooling in subcooler (Y).
The present invention and prevailing system relatively have following advantage: system architecture is simple, cancelled the drain valve that is disposed at hot equipment, reduce system cost, reduced maintenance load, eliminated the prevailing system existence variety of issue, solved the problem of whole recovery condensate water, use the heat energy utilization rate of hot equipment to bring up to more than 90%.
