Abstract

The utility model belongs to a pressureless hot-water boiler for heat supply-a pressureless hot-water boiler with double water chambers and water pipes, and the utility model is the heat supply equipment of factories, schools, institutions and houses owned by citizens. A water chamber is respectively arranged on the right and the left of a boiler, and a convection pipe is arranged transversally to make the right and the left water chambers communicate to compose a circulation water channel. A finned pipe is used for doing a partition wall in the zone of the convection pipe to compose three smoke channels of return travel. A cyclone dust removal chamber is arranged on the front part of a boiler body, and the cyclone dust removal chamber is used for cyclone dust removal in the boiler whose outside is provided with a smoke reversing chamber, and the inner side of a front panel is provided with a hot-wind pipe to supply hot wind to an upper furnace chamber. The boiler body, a dust-removal device and a wind inducing and a muffler devices are combined into integration. The utility model which is suitable for the pressureless hot-water boiler of 0.06MW-0.7MW has the advantages of compact structure, complete combustion, fast temperature rise and good smoke and dust abatement.

Description

Double-water chamber water pipe pressureless boiler for heating water

The utility model belongs to the heat supply unpressurized hot water boiler.

Existing double-layer grate back burns the unpressurized hot water boiler, mostly is that the garden drum is vertical, horizontal type structure, convection tube can't be realized high-density arrangement, heating surface is little, the thermal efficiency is low; The outside no air inducing dust arrester of vertical boiler, with increasing the combustion efficiency that chimney improves boiler, it is slow to heat up, and dust removing effects is poor; Be furnished with air-introduced machine, the boiler external flue of deduster is long, and subsidiary engine is arranged loose, and floor space is big, and boiler and subsidiary engine steel quantity consumption are big, the cost height; Anti-burn grate upper furnace hearth air intake is controlled with the unlatching upper furnace door, and what advance is that cold wind is unfavorable for burning, and mid-feather is with building block method, poor sealing performance.

The purpose of this utility model provides a kind of New-type boiler, and the structural change of the two hydroeciums of utilization has the traditional design of boiler now, makes convection tube high-density arrangement increase heating surface in body, and steel quantity consumption is reduced; Anti-burning stove upper furnace door need not opened just can be to the upper furnace hearth hot wind supply to promote burning of coal; The sealing of improvement mid-feather; Improve the dedusting in stove effect, realize the boiler electromechanical.

Another purpose of the present utility model provides that a kind of smoke evacuation, dirt, concentration that is applicable to that a class environmental protection city requires is low, noise is little, quick heating, heating boiler that combustion efficiency is good, energy-efficient.

Technical solutions of the utility model are: a hydroecium respectively is set, with the convection tube of lateral arrangement, make the left and right sides hydroecium formation circulation waterway that communicates about boiler body; The front panel inboard is provided with warm-air pipe, gives the upper furnace hearth hot wind supply; Do partition wall with extended surface tube convection tube is separated into three backhauls; The upper furnace hearth top is provided with the cyclone dust removal chamber, is used for cyclone dust removal in the stove; Boiler body, dust arrester, air inducing, silencing apparatus are integrated, and make the boiler structure compact and reasonable.

The two hydroecium water pipe unpressurized hot water boilers of the utility model can satisfy the requirement in a class environmental protection city, the two hydroecium water pipe unpressurized hot water boilers of 0.35MW, and during heavy-duty service, dust exhausting concentration is less than 150Mg/NM ³, the dark brown blackness less than graceful 1 grade of woods, exhaust gas temperature 150-160 ℃, noise less than 75 decibels, the long-pending 25.4M of total heating surface ², 1650 kilograms of body steel quantity consumptions.

Fig. 2 is the A-A profile of the utility model front view.

Fig. 3 is the utility model external form figure

The utility model course of work can illustrate in conjunction with Fig. 1, Fig. 2, Fig. 3:

Extraneous air by afterbody air door (1), enter hot-flow flue (2) preheating, from front and both sides through fire grate (3), warm-air pipe (4), respectively to upper furnace hearth (5), down stove hall (6), hot blast is provided; Coal is in upper furnace hearth (5), just fall down stove hall (6) after the combustion, burn away, in air inducing (16), flue gas is through first flue (7) under the suction function, to cyclone dust removal chamber (8), the cigarette speed of entering the cyclone dust removal chamber is 15M/S, because dust is separated in the centrifugal action flue gas, flue gas is through whirlwind mouth (9), enter down smoke-box (10), after the dust sedimentation for the second time, flue gas is through return air inlet (11), enter second flue (12), descend, bending is risen through the 3rd flue (13), from outlet flue (14), via dust arrester (15), air inducing (16), silencing apparatus (17), chimney (18), enter atmosphere.
