Abstract
The utility model relates to a hot water boiler. A secondary air inlet pipe is additionally added at the bottom of the boiler. The outer wall of the inner casing of the boiler is provided with an annular air box and an air generating box. The secondary air inlet pipe is communicated with an air blast box and the annular air box which is communicated with a boiler hearth through an air nozzle. The lower end opening of the inner part of the air generating box is provided with a float valve and is communicated with a water chamber. The upper end opening of the air generating box is communicated with the air blast box through an air delivery pipe. The utility model has the advantages that the coal is thoroughly and sufficiently combusted through the secondary air supply, the dust concentration is reduced, the environment pollution is reduced and the heat utilization rate is enhanced.
Description
The utility model relates to a kind of hot-water boiler.
A kind of hot-water boiler structure that extensively adopts is at present: the annular water chamber that constitutes sealing between the shell body of boiler and the inner housing, hydroecium communicates with water inlet pipe and outlet pipe respectively, be provided with the flue and the heating pipe that communicate with hydroecium above the burner hearth in inner housing, the below of burner hearth is provided with blast pipe one time.In burner hearth, the water among flue and the heating pipe is heated by the burning of coal release heat.This kind hot-water boiler in use, coal combustion is insufficient, produces the black smoke serious environment pollution, heat utilization ratio is low simultaneously, wastes energy.
The purpose of this utility model provides a kind of hot-water boiler, and it can make coal fully burn, and reduces environmental pollution, improves the utilization rate of heat simultaneously.
The purpose of this utility model is achieved in that
In the boiler bottom increase secondary wind inleting tube is set, on the outer wall of boiler inner housing, be provided with annular bellows and aerogenesis case, one end of secondary wind inleting tube is communicated with annular bellows, annular bellows communicates with burner hearth by the tuyere that has on the inner housing, the lower port of aerogenesis case and communicate by the annular closed hydroecium that forms between inner housing and the shell body, lower port place in aerogenesis case inside is provided with ball-cock assembly, the upper end of aerogenesis case is provided with snorkel, and the other end of snorkel and secondary wind inleting tube is communicated in bellows jointly.
Owing on the inner housing outer wall, increase and be provided with annular bellows and aerogenesis case, air-supply by the secondary blast pipe, make the air of annular bellows and the steam in the aerogenesis case, heated in annular bellows, by the tuyere of different angles is set on the inner housing, high-temperature gas carries out helping the second time so to coal combustion in burner hearth again, make coal thoroughly fully burn, improve the thermal efficiency with this, and reduce black smoke concentration, reduce the pollution of coal smoke environment.
Below in conjunction with embodiment embodiment of the present utility model is described:
Fig. 1 is a front view of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Fig. 3 is that the B-B of Fig. 2 is to cutaway view.
The airtight hydroecium of looping (10) between shell body (9) and the inner housing (5), on shell body (9), be provided with water inlet pipe (12) and outlet pipe (13), pass shell body (9) in the upper end of inner housing (5) and be provided with outlet flue (14), be provided with a blast pipe (1) and secondary wind inleting tube (4) at boiler bottom, one end of a blast pipe (1) is communicated in bellows (2), its other end is corresponding with burner hearth (3), on the outer wall of boiler inner housing (5), be provided with annular bellows (6) and aerogenesis case (7), one end of secondary wind inleting tube (4) is communicated with annular bellows (6), annular bellows (6) communicates with burner hearth (3) by the tuyere (8) that has on the inner housing (5), the lower port of aerogenesis case (7) and annular closed hydroecium (10) communicate, the lower port place inner at aerogenesis case (7) is provided with ball-cock assembly (19), the upper end of aerogenesis case (7) is provided with snorkel (11), snorkel (11) is communicated in bellows (2) jointly with the other end of secondary wind inleting tube (4), the inwall of the top inner housing (5) of burner hearth (3) is provided with flue (15) and the heating pipe of arranged vertical (16) successively, flue (15) bottom is provided with the flue water inlet pipe (17) that communicates with hydroecium (10), flue (15) top is provided with the flue outlet pipe (18) that communicates with hydroecium (10), and heating pipe's (11) two-port up and down all communicates with hydroecium (10).
