Abstract
The utility model discloses a double-furnace hearth boiler, aiming at solving the problems that the heat utilization of the boiler is low, the pollutant emission is serious, and the heating time is long. The double-furnace hearth boiler comprises a main boiler and a subsidiary boiler, wherein the top of the main boiler and the top of the subsidiary boiler are connected with each other by a smoke passageway, a water inlet pipe is arranged at the lower part of the subsidiary boiler, the top of the subsidiary boiler is provided with a water pipe which is communicated with the bottom of the main boiler, the top of the main boiler is provided with a water outlet pipe, and the bottom of the subsidiary boiler is provided with the smoke passageway. The subsidiary boiler can adequately recycle the waste heat of the smoke of the main boiler, so that the double-furnace hearth boiler improves the heat utilization ratio; the smoke is discharged by a chimney after being treated by a dissolving tank, so that the double-furnace hearth boiler can reduce the discharge quantity of the pollutant and is beneficial to protecting the environment; and the cold water enters the main boiler after being preheated by the subsidiary boiler, so that the double-furnace hearth boiler can accelerate the heating time, can keep the unified environment in the boiler, and can prolong the service life of the boiler.
Description
Technical field
The utility model relates to boiler, is specifically related to a kind of twin-furnace boiler.
Background technology
Traditional boiler generally has only a main stove, in use, directly cold water is added in the boiler, can make that the hot water in original boiler becomes cold water rapidly, has prolonged heat time heating time; And influence service life of boiler easily; The high-temperature flue gas that boiler produces generally just directly is discharged in the atmosphere after simple the processing, and not only heat utilization efficiency is low, and causes environmental pollution easily.
Summary of the invention
The utility model is low in order to solve existing boiler hot utilization rate, and pollutant emission is serious, and the problem of growing heat time heating time, and a kind of twin-furnace boiler is provided.
The utility model is achieved through the following technical solutions:
A kind of twin-furnace boiler comprises main stove and attached stove that the top links to each other through exhaust gases passes, and attached stove bottom is provided with water inlet pipe, and the top is provided with the water pipe that communicates with main furnace bottom, and the top of main stove is provided with outlet pipe, and the bottom of attached stove is provided with flue.During use, add the heating of burning of raw material such as coal in the main stove fire grate, main stove links to each other with the exhaust gases passes of attached furnace roof portion, waste heat in the main stove enters attached stove together through flue gas, and after the cold water in the attached stove fully absorbed the waste heat in the flue gas, flue gas entered the flue of attached furnace bottom, cold water enters in the attached stove from the water inlet pipe of attached stove bottom, after preliminary preheating from attached stove in water pipe enters main stove, after abundant heating, from the outlet pipe discharge of main furnace roof portion.
Further, also be provided with a dissolving tank that links to each other with flue, be used for further dedusting, desulfurization, to reduce the pollutant emission of boiler.
Also comprise an air-introduced machine, flue links to each other with dissolving tank through air-introduced machine.
The end of air-introduced machine is provided with a sheave, is provided with water wheels in the dissolving tank, and sheave links to each other with water wheels, is rotated by the Motor Drive sheave, rotates thereby drive water wheels, forms spray, improves the efficient of desulfurization and dedusting.
The utility model compared with prior art has the following advantages:
(1) attached stove can be recycled the fume afterheat of main stove fully, improves the heat utilization efficiency of boiler;
(2) flue gas again through smoke stack emission, can reduce the discharge capacity of pollutant after dissolving tank is handled, and helps environmental protection;
(3) cold water enters main stove again after attached stove preheating, can accelerate heat time heating time, and keep the environment in the stove unified, the service life that can improve boiler.
