Abstract
The utility model relates to a boiler energy-conserving cooling water system device, especially to a cooling system for water vapor sample of a dry quenched coke boiler, for mainly resolving the technical problems that the original cooling water system pipe is easy to clog, corrode and scale. The technical scheme of the utility model is that the cooling system for water vapor sample of the dry quenched coke boiler comprises a desalted water tank, wherein the desalted water tank is arranged with a desalted water inlet pipe and a desalted water outlet pipe, one side of the desalted water tank is arranged with a primary cooler and a secondary cooler which are connected in series, the upper of the primary cooler is communicated with the upper of the desalted water tank by a cooling water discharge pipe, the secondary cooler is connected with a feedwater pump through a cooling water isolation valve and a feedwater pump outlet pipe by the cooling water inlet pipe, the feedwater pump is communicated with the desalted water outlet pipe by the feedwater pump inlet pipe, and the vapor sampling tube is through the primary cooler and the secondary cooler in sequence. The cooling system of the utility model is mainly used for cooling water vapor sample of a dry quenched coke boiler.
Description
Technical field:
The utility model relates to a kind of boiler energy-saving type cooling water system device, particularly a kind of cooling system of coke dry quenching boiler water and steam sampling.
Background technology:
Be used to cool off that the two-stage chilled water of dry coke quenching (CDQ) boiler water and steam sampling adopts is the simply dealt service water of Yangtze River Water to be established pipeline in addition by supercharge pump be delivered to refrigeratory, directly discharge the cooling back.The waste at water source and the loss of heat have been caused, and because impurity content is higher in the service water, often cause the obstruction and the corrosion and scaling of cooling water system pipeline easily, in case refrigeratory occurring reveals, cause bad influence for the online chemical supervision of normal steam, and cause the pollution of electrode cell and the filter core of frequent replacing water sample filtrator easily.
The utility model content:
The purpose of this utility model provides a kind of cooling system of coke dry quenching boiler water and steam sampling, mainly solves the technical matters of easy obstruction of former cooling water system pipeline and corrosion and scaling.
For overcoming the above problems, the technical solution adopted in the utility model is: a kind of cooling system of coke dry quenching boiler water and steam sampling, comprise sweet-water tank, sweet-water tank is provided with demineralized water water inlet pipe and demineralized water rising pipe, sweet-water tank is other to be provided with the refrigeratory and the recoler of series connection successively, No. one time refrigeratory top is communicated with sweet-water tank top by the chilled water drainpipe, recoler passes through cooling water inlet pipe successively through the chilled water barrier valve, the feed pump rising pipe is connected with feed pump, feed pump is communicated with the demineralized water rising pipe by the feed pump water inlet pipe, and steam sampling pipe priority is successively through refrigeratory and recoler.
The beneficial effects of the utility model:
1, the utility model forms closed circuit, and quality of cooling water improves, and avoids the line clogging corrosion and scaling;
2, the power of cooling water source adopts the discharge connection of feed pump, does not need to acquire in addition supercharge pump;
3, the drainpipe of chilled water directly is connected to the top of sweet-water tank, the cooling draining after temperature is raise is recovered to sweet-water tank.The cooled heat of steam is all reclaimed;
4, improve the CDQ thermal efficiency.
Description of drawings:
Fig. 1 is the utility model structural representation
Among the figure: 1-feed pump water inlet pipe; The 2-feed pump; 3-feed pump rising pipe; 4-chilled water barrier valve; The 5-cooling water inlet pipe; The 6-recoler; 7-cooling back steam sampling pipe; Refrigeratory of 8-; Steam sampling pipe before the 9-cooling; The 10-sweet-water tank; 11-demineralized water water inlet pipe; 12---the sweet-water tank rising pipe; 13-chilled water drainpipe.
Embodiment:
With reference to Fig. 1, a kind of cooling system of coke dry quenching boiler water and steam sampling, comprise sweet-water tank 10, sweet-water tank is provided with demineralized water water inlet pipe 11 and demineralized water rising pipe 12, sweet-water tank is other to be provided with the refrigeratory 8 and the recoler 6 of series connection successively, No. one time refrigeratory 8 tops are communicated with sweet-water tank 10 tops by chilled water drainpipe 13, recoler 6 passes through cooling water inlet pipe 5 successively through chilled water barrier valve 4, feed pump rising pipe 3 is connected with feed pump 2, feed pump 2 is communicated with demineralized water rising pipe 12 by feed pump water inlet pipe 1, steam by cooling before steam sampling pipe 9 successively successively through refrigeratory 8 and recoler 6, discharge from cooling off back steam sampling pipe 7 at last.
During use, behind the unlatching feed pump 2, open sampling chilled water barrier valve 4 and the preceding steam sampling pipe 9 of cooling again.Demineralized water enters recoler 6, and pressure also can be guaranteed; Chilled water enters refrigeratory 8 No. one time then, and the demineralized water after cooling heats up flows to sweet-water tank 10, and chilled water and heat have obtained recovery.Cause scorching of in-line meter for fear of the interruption of chilled water, before feed pump 2 starts, guarantee to close earlier steam sampling pipe 9 and chilled water barrier valve 4 before the cooling of sampler.After the enforcement of such scheme, quality of cooling water is improved, avoid the line clogging corrosion and scaling, avoid the in line waste of cooling water source, the cooled heat of steam is all reclaimed, and improves the CDQ thermal efficiency.
