Description
Technical field
The utility model relates to a kind of heating boiler, relates in particular to a kind of horizontal hot-water heating boiler of energy-conserving and environment-protective.
Background technology
The boiler industry of China is the industry of a development.After the eighties in 20th century, there is the variation of advancing by leaps and bounds in the economy of China, and boiler industry also development grows.End 2012, thousands of families of national Boiler Manufacturing Enterprise, and stand-alone development is developed generation by generation new product separately, and how energy-conservationly become the large chip that can Boiler Manufacturing Enterprise win in this industry.
Coal-fired as one of energy of boiler, belong to nonrenewable resources, therefore, must consideration how to improve the degree of absorption of energy entrained in coal-fired abundant degree of burning and coal-fired rear flue gas in boiler.Make coal-fired burning in boiler afterwards than the past and the same period other boiler thermal conversion efficiency higher, more environmental protection.
At present, the Horizontal atmospheric water boiler existing on market is all to have a forward combustion chamber, two backhauls or the three return-stroke ordinary pressure Horizontal boiler for heating waters that by the threaded flue of a backhaul or two backhauls and smoke box etc., are formed, its flue, the first return thread or the first return thread and the second return thread are arranged in shell, during use, can water will be full of in shell.Smoke box is arranged on outside shell.Flue is horizontally set on shell bottom, and the first return thread or the first return thread and the second return thread are horizontally set on flue top.Flue, the first return thread or the first return thread are connected successively with the second return thread, and flue gas enters atmosphere from flue enters the first return thread or the first return thread and the second return thread.These boiler furnaces are one, forward combustion, coal seam thickness is thick, burn insufficient, easy over-emitting black exhaust, in flue gas with toxic gas and the dusts such as unburned water-gas and particle, contaminated environment.High-temperature flue gas is directly discharged with speed faster from chimney by short line, and flue-gas temperature during discharge is high, and dust is many, neither energy-conservation, not environmental protection again, and thermal conversion efficiency is very low, has wasted the energy.
Summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides that a kind of rational in infrastructure, sufficient combustion, thermal conversion efficiency are high, non-environmental-pollution, practical anti-being burned four combustion chamber Horizontal atmospheric water boilers.
For completing above-mentioned purpose, technical solution of the present utility model is: a kind of anti-being burned four combustion chamber Horizontal atmospheric water boilers, and it comprises shell, three combustion chambers, secondary combustion chamber, the first backhaul smoke pipe and the second backhaul smoke pipes, is arranged on the smoke box outside shell; Lower end is horizontally disposed in shell three combustion chambers, and upper end is horizontally disposed the first backhaul smoke pipe and the second backhaul smoke pipe, and in shell, left end or the right-hand member of three combustion chambers are provided with the secondary combustion chamber higher than three combustion chambers; The water-cooled grate of being made by water pipe of being fixed by centre in each combustion chamber is divided into upper combustion chamber and the combustion chamber of being left, water-cooled grate relative level face tilt; The upper combustion chamber of intermediate combustion chamber has secondary throat and with the coal feeding hole of stoking door, there is breast hole and the air inlet with clean-out door the combustion chamber of being left; The upper combustion chamber of the combustion chamber on both sides has secondary air inlet and with the coal feeding hole of stoking door, there is the breast hole with clean-out door the combustion chamber of being left; The upper combustion chamber of intermediate combustion chamber is communicated with by passage of flame respectively with the upper combustion chamber of combustion chamber, two ends, and the combustion chamber of being left of combustion chamber, two ends is communicated with secondary combustion chamber by exhaust gases passes; On secondary combustion chamber, be provided with shoot door, its outlet flue connects the gas approach of each smoke pipe of the first backhaul smoke pipe; The exhanst gas outlet of each smoke pipe of the first backhaul smoke pipe connects the mouth that enters of smoke box, the outlet flue of smoke box connects the gas approach of each smoke pipe of the second backhaul smoke pipe, and the exhanst gas outlet of each smoke pipe of the second backhaul smoke pipe is directly connected with chimney by air-introduced machine by smoke pipe or again by being connected with chimney after water bath desulfurization dust removing; There are water return outlet and soil cleaning port in the lower end of shell sidewall, has hot water outlet and pressure relief opening on roof.The utility model is positioned on the ashcan on basis and can be used, in ashcan, have ash disposal mouth.
The utility model is only at middle combustion chamber forward combustion, two combustion chamber reverse burnings on both sides, so, the flue gas of the burning of forward combustion chamber and the not little coal particle of burning of carrying secretly enter respectively the combustion chamber on both sides, the combustion chamber of being left that the little coal particle of the flue gas of the combustion chamber on both sides and not burning enters respectively its lower end burns away, and the water-gas in the flue gas that does not finally have to burn burns away at secondary combustion chamber.Like this, coal tegillum grate firing burns, and the flue gas of generation carries out second-time burning second-time burning is indoor again, and its burning very abundant no longer insufficiently produces black dense smoke because burning, and in flue gas, no longer contains and there is no the water-gas that burns.The heat that flue gas carries is fully absorbed in the first backhaul smoke pipe and the second backhaul smoke pipe, and the flue-gas temperature entering in chimney is very low; And secondary combustion chamber and the passageway so long and that bend of flue gas through also using as expansion chamber, its dust carrying is also kept off completely, and the flue gas of going out from chimney has not had dust, and it no longer causes contamination by dust, through the flue gas of water bath desulfurization dust removing, its toxic gas pollution is also eliminated.In a word, the utility model burning very fully, thermal conversion efficiency is very high, environmental pollution is little; And it is rational in infrastructure, volume is little, boiler step-down, and easily maintenance, repair, practical.
