Abstract

The utility model relates to a combined normal-back-burning energy-saving fume-eliminating and dust-controlling water-heating boiler, which is a vertical boiler composed of an upper and a lower two sections which are combined, wherein, the upper section is composed of a fire pipe, a water pipe, a dust collecting box and a cone-shaped flue, and the lower section is composed of a boiler chamber, a frame type back-burning grate and a frame type normal-burning fixed grate to form a normal-back-burning chamber. The boiler chamber has high temperature, good ventilation, strong firepower and high thermal efficiency, and the utility model has good fume-eliminating and dust-controlling effect.

Description

Combined type is combustion energy saving smoke abatement and dust control hot-water boiler anyway

The utility model relates to a kind of combined type combustion energy saving smoke abatement and dust control hot-water boiler anyway.Known coal-burning boiler, no matter tonnage size, even is an integral body, in transportation, very inconvenient when installing and keeping in repair, be furnished with the boiler of anti-burn grate, its anti-burn grate also has only one deck water pipe, grate area is little, ventilation condition is poor, and incomplete combustion had both been wasted fire coal, over-emitting black exhaust again, be single water pipe or single fire tube only on heat exchange structure, heating surface area is little, and the thermal efficiency is low, be difficult for catching dust again, cause volume of smoke to efflux contaminated environment, often be equipped with deduster in addition and solve the flue dust problem, can increase boiler running energy consumption and expense like this.

Task of the present utility model is, a kind of combined type combustion energy saving smoke abatement and dust control hot-water boiler anyway is provided, and may overcome above-mentioned existing problems fully.

Solution of the present utility model is that boiler is divided into two sections by upper box combination and lower box combination, by connecting band location recombinant one, constitutes the circulation of body of heater water by connecting water pipe UNICOM water cavity.Bring convenience to segmentation transportation, installation and maintenance.Two to three water pipes respectively are equipped with in both sides in the burner hearth above the anti-burn grate individual layer water pipe, constitute the frame anti-burn grate, increased grate area, the burning fire bed can be thickeied, improved ventilation condition, make the interior flame of burner hearth more prosperous, burn again from disclosing unburnt charcoal fire on the stove goalkeeper anti-burn grate, disclose to fall on the fixed grate, through positive and negative to the burning, firepower is strengthened in the burner hearth, the flame temperature height, and burning is fully.Flue gas is in burner hearth after the completing combustion, rise through fire tube, successively enter three grades of collection flue dust casees, dust in flue gas is detained step by step, and clean flue gas is discharged to the atmosphere outside tubular porous flue, after the utility model is implemented, but fire coal completing combustion, firepower is prosperous, and the water cavity heating surface area is big, can reach fully and economize on coal, the high and smoke abatement and dust control purpose of the thermal efficiency.

Below in conjunction with accompanying drawing the utility model is elaborated

Fig. 4 is Figure 1B-B cutaway view

Fig. 5 is the utility model tubular porous flue (8) profile

The utility model is combined integrated by connecting band (5) location by upper box combination (7) and lower box combination (4).In upper box combination (7), by horizontal water tube (17,18) form collection flue dust case (19), the collection cigarette is given birth to case (19) and is communicated with secondary ring-type collection flue dust case (14) by vertical fire tube (15), Taper Pipe or pyramid pipe (13) communicate with secondary ring-type collection flue dust case (14) and three grades of tubular collection flue dust casees (9), have plurality of rows pore (8a) on tubular porous flue (8) barrel, its hypomere is a cone shape, and be provided with cone and protect skirt (8b), in lower box combination (4), fire tube (21) communicates with collection flue dust case (19) and burner hearth (22), the top both sides of the inherent individual layer water pipe of burner hearth (24) respectively are provided with two to three water pipes (23) and form the frame anti-burn grate, utilize fire door (1), 3) and disclose vent (2) and can conveniently add new coal, disclose fire or scarfing cinder work, cast iron fixed grate (27) and water pipe (25) constitute the positive combustion grate of frame.Cross over pipe (6) UNICOM water cavity (11,20) constitutes the circulation of body of heater water, and water pipe (10,26) constitutes the outer water circulation of stove, and cleaning door (12,16) makes and is deashing dirt window.

Secondary tubular collection flue dust case of the present utility model (9) hypomere is a cone shape, and fire tube (15,21) is a seamless steel pipe, and section is a garden shape or square.
