Abstract

The invention discloses an automatic blanking barotropic stove with sulfur fixation, denitration and dedusting functions. One side of a hearth fire outlet of the stove is provided with a fire outlet channel. The fire outlet channel is communicated with a smoke box and a dedusting solution box assembly. A dedusitng solution box in the dedusitng solution box assembly is arranged below the smoke box. A hearth is communicated with a discharging bin. A feeding opening is formed above the discharging bin. A residual smoke collecting system is arranged between the feeding opening and the hearth, so that the residual smoke flowing to the feeding opening from the discharging bin is induced into the hearth through the residual smoke collecting system. The upper portion of the hearth is provided with a hearth heat accumulation device. According to the stove, an automatic blanking barotropic burning mode is adopted for the fuel in the hearth, heat efficiency is high, meanwhile a sulfur fixation device, a denitration device and a dedusting device are additionally arranged, a better effect of all environmental-protection emission indexes is achieved, and the stove is a real civilian energy-saving environmentally-friendly stove.

Description

There is the automatic blanking malleation stove and accessory of solid sulphur denitration dust collecting function
Technical field
The present invention relates to a kind of civilian malleation stove and accessory, particularly a kind of civilian automatic blanking malleation stove and accessory with solid sulphur denitration dust collecting function.
Background technology
The civil heating stove and accessory of peasant household's use is in the market the mode adopting negative-pressure firing mostly, and high fume temperature is not energy-conservation.And civil heating stove and accessory is on the market all generally just directly be thrown in air by dust without any process at present, and atmosphere pollution, the environment making the mankind depend on for existence is constantly destroyed.
Even if the civil heating stove and accessory of the existing pressure combustion mode adopted emerges now, but it is just directly be thrown in air by dust without solid sulphur, denitration, dust removal process equally, causes atmosphere pollution.
Summary of the invention
The object of the invention is for the not energy-conservation defect not environmentally of civil heating stove in the market, there is provided a kind of and can carry out solid sulphur, denitration, dust removal process to the dust that burning produces, realize flue gas qualified discharge, and structure is simple, small investment, solid sulphur denitration without operating cost, easy to operate, the safe and reliable civilian malleation stove and accessory with solid sulphur denitration dust collecting function.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of automatic blanking malleation stove and accessory with solid sulphur denitration dust collecting function, comprise burner hearth and assembly is overlapped at the end, blower fan and air distribution device, described burner hearth and the end, overlapped burner hearth in assembly and the end and overlap and be structure as a whole, this burner hearth and blanking bin connect, and set out burner above burner hearth, blanking bin top arranges charge door, end cover is arranged at burner hearth bottom, and the end, puts and arranges grate, described blower fan and air distribution device respectively with the Secondary Air interface being located at upper furnace be located at the First air interface that the end puts and be connected, it is characterized in that, the top of described crater is equipped with fire-banking plate, the side of described crater arranges the passage that fires, this fire channel connection one smoke box and dedusting liquor box assembly, dedusting liquor box in described smoke box and dedusting liquor box assembly is arranged on the below of smoke box, remaining cigarette gathering system is set between described charge door and described burner hearth, makes to alter to cigarette more than charge door from blanking bin to cause in burner hearth through remaining cigarette gathering system.
Described remaining cigarette gathering system is the jockey be arranged between charge door and burner hearth.Because stove and accessory provided by the present invention is malleation stove and accessory, the high-temperature region of more than 1200 degree can be formed in burner hearth, coal in blanking bin can form the destructive distillation low-temperature space of less than 400 degree by the impact of high temperature in burner hearth, coal is under burner hearth hot conditions, calcium carbonate composition in coal resolves into calcium oxide, and produce containing sulfur dioxide during the dry distillation of coal at this moment in blanking bin, the remaining cigarette such as hydrogen sulfide, cigarette gathering system is introduced in burner hearth to produce with calcium oxide and reacts and generate sulfate more than arrange between charge door and burner hearth, the sulfur dioxide constantly produced in such blanking bin destructive distillation and hydrogen sulfide react with the calcium oxide in burner hearth again continuously, serve good sulfur fixation.
The neck position suspension Accumulated Heat Units of described burner hearth.The effect of described Accumulated Heat Units is burner hearth crater temperature to be improved more than 150 degree, thus reduces the oxygen content in flue gas, the oxygen element in nitrogen oxide is reduced and reduces the growing amount of nitrogen oxide, reaching the object of denitration.
Be provided with many fire tubes in described smoke box to be connected with the passage that fires, the lower ending opening of many fire tubes communicates with the dedusting liquor box being located at smoke box bottom, the side of many fire tubes arranges smoke pipe, smoke pipe upper, smoke box is stretched out in lower end, filling water body in described smoke box, when fire and flue gas from burner hearth through crater, after the passage that fires enters the fire tube in smoke box, the water body in smoke box is heated while coming downwards to smoke box bottom along fire tube, when fire and flue gas are after the dedusting liquor box that fire tube enters bottom, in flue gas, the particle of entrained with directly falls in dedusting liquor box, flue gas is upwards discharged from smoke pipe in the other direction along 180 degree rapidly.
The present invention efficiently solves current civil heating stove when using common bituminous coal combustion, efficiency of combustion is low, sulfur dioxide, nitrogen oxide, a difficult problem that granular material discharged index is high, not only substantially increase civil heating stove combustion thermal efficiency, and the present invention adds solid sulphur, denitration, dedusting structure on civil heating stove, without the need to adding desulfurizing agent, denitrfying agent and increasing operating cost, the qualified discharge of waste gas just can be realized.
Below in conjunction with accompanying drawing, the present invention will be further described.
