Abstract
The utility model relates to a composite circular industry water pipe boiler, composed of a natural circulation boiler, combustion equipment, a boiler wall steel frame, and a boiler body. The utility model is characterized in that a separating plate is arranged in an upper and the lower containers of a water cooled wall of the boiler body, a connecting pipe is arranged between the two containers and a front arch lower container, a connecting pipe is arranged between a rear arch upper container and the upper container of the water cooled wall, dropping pipes arranged among an upper boiler cylinder of the boiler body, a rear arch lower container the upper boiler cylinder, and two lower containers on the water cooled wall and a connecting pipe arranged between the upper container on the water cooled wall and the upper boiler cylinder are respectively provided with a valve. The utility model has a double-structure of a forced circulation and a natural circulation, and has the advantages of eliminating the circulatory obstacle of working medium as well as realizing the protection of failure power.
Description
The utility model relates to the boiler technology field, particularly relates to a kind of novel water cycle industrial water-tube boiler.
At present; boiler is divided into two kinds of forced circulation boiler and natural circulation boilers by working medium in the endless form of boiler internal; forced circulation boiler is forced working medium to flow in pipe by pump and is kept certain flow rate; its shortcoming is that the power-failure protecting function is poor; when having a power failure, working medium stops to flow, if when working medium is water; in pipe, easily produce vaporization and water attack, cause that boiler vibration causes damage in boilers when serious.The circulation of natural circulation boiler working medium be by working medium in institute's received heat difference of different heating surfaces, density is different to be produced mobilely, its shortcoming is easily to form working medium dyshaemia, working medium is stagnated, the scope of freedom and flow backwards and can cause tube wall burning and booster to damage boiler.
The purpose of this utility model provides a kind of combined-circulation industry water pipe boiler, to solve the deficiency that forced circulation boiler power-failure protecting function is poor, natural circulation boiler easily forms working medium dyshaemia.
The technical solution of the utility model is: part-structures such as existing natural circulation boiler combustion apparatus, furnace wall steelframe are constant substantially, are welded with dividing plate in the upper and lower collection case of boiler body water-cooling wall, are welded with tube connector between water-cooling wall two next part casees and face arch next part case; Be welded with tube connector between rear arch upper collecting chamber and the water-cooling wall upper collecting chamber, be welded with tube connector between economizer exit collection case and the rear arch next part case, on the down-comer between boiler body upper drum and rear arch next part case, upper drum and the water-cooling wall two next part casees, be welded with flange, be welded with tube connector and flange between water-cooling wall upper collecting chamber and upper drum, each flange is fixed with the valve fitted bolt respectively.
Compared with the prior art the utility model because structure of boiler body changes a little, makes it have forced circulation and Natural Circulation dual structure concurrently, and its advantage is to have eliminated working medium dyshaemia, can realize power-failure protecting again.
Accompanying drawing is a kind of combined-circulation industry water pipe boiler structural representation.
Provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing: part-structures such as existing natural circulation boiler combustion apparatus, furnace wall steelframe are constant substantially, in the upper and lower collection case 1,2 of body water-cooling wall, be welded with dividing plate 3, be welded with tube connector 5 at water-cooling wall two next part casees 2 and 4 in face arch next part case; Be welded with tube connector 7 between rear arch upper collecting chamber 6 and the water-cooling wall upper collecting chamber 1; Be welded with tube connector 14 between economizer exit collection case and the rear arch next part case 9, on the down-comer 10 between body upper drum 8 and rear arch next part case 9, upper drum 8 and the water-cooling wall two next part casees 2, be welded with flange, be welded with tube connector 11 and flange between water-cooling wall upper collecting chamber 1 and upper drum 8, each flange is fixed with valve 12 fitted bolts respectively.Dividing plate 3 materials are Q235-AF, tube connector 5,7,11,14 materials are the 20# steel pipe, valve 12 models are ZCLF, under normal circumstances, valve 12 is in closed condition, the boiler cycle fluid is via economizer 13, rear arch next part case 9, tube connector 14, rear arched tube, rear arch upper collecting chamber 6, tube connector 7, water-cooling wall upper collecting chamber 1, under 3 effects of water-cooling wall upper collecting chamber 1 median septum, flow to water-cooling wall next part case 2 through water screen tube 16, under 3 effects of water-cooling wall next part case 2 median septums, flow to water-cooling wall upper collecting chamber 1 reciprocal again to several times, again via tube connector 5, face arch next part case 4, preceding arch tube, the face arch upper collecting chamber, tube connector 15 arrives upper drum 8 between face arch upper collecting chamber and upper drum 8 again, afterwards at upper drum 8, convection bank 17, Natural Circulation between the lower drum, the back is flowed out by upper drum 8 again.When having a power failure, valve 12 is opened automatically, and each down-comer is responsible for supplying with working medium, forms a plurality of natural convection loops, plays the power-failure protecting effect.
