Abstract
The utility model relates to a civil device which converts coal into gas fuel. The utility model adopts a fixed bed. Air is used as a medium. Coal is added and slag is removed manually. An internal liner and a heat insulating layer are arranged in the device. An oxygen distributing disc is arranged at the bottom part of the device. The air is uniformly distributed at the bottom part of a hearth through the oxygen distributing disc and an ash and slag layer, the air contacts with the coal and oxygen supply amount is control manually. The coal is heated and then burns under anoxic condition. Passing through an oxidation layer, a reduction layer, a carbonization layer, a drying layer and a hollow layer in turn, coal gas is discharged out of the hearth. The utility model effectively solves the problems of heavy environmental pollution, high heat loss, heavy fuel waste, low fuel utilization ratio and the like when the coal burns directly and meanwhile spares the laying of a coal gas pipe network. Compared with a large-scale coal gas station, the utility model is convenient to use, has the advantages of low cost and more extensive application range, in particular to better flexibility and is more applicable to personal use.
Description
Technical field
The utility model relates to and a kind ofly converts fire coal the device of geseous fuel to, particularly a kind ofly is applicable to civilian producer gas generator.
Background technology
At present, at the civil area fire coal all is direct burning, environmental pollution is heavy, thermal losses is high, waste of fuel is bigger, fuel availability is low is ubiquitous problem, to be the optimal path that addresses these problems in utilization behind the coal-fired gasification, and industrial coal-fired gasification furnace be at civil area and inapplicable.
Summary of the invention
The purpose of this utility model provides a kind of problems such as civilian coal-fired gasification furnace is heavy with the environmental pollution that the coal-fired directly burning of solution civil area is brought, thermal losses is high, waste of fuel is bigger, fuel availability is low that are applicable to; save the mass-producing gas station simultaneously and lay the work of gaspipe network, make its scope of application wider, have more handiness.
The technical solution of the utility model is to adopt fixed bed, with the air is medium, hand firing, artificial slagging-off, this stove top adopts miniature coal-fired gasification furnace special cap (to declare the utility model patent technology, name is called miniature coal-fired gasification furnace special cap), the middle part body of heater is divided into three layers and is followed successively by from inside to outside: inner bag adds fire-resistant mortar by unburned formula coal-fired gasification furnace burner hearth liner tile (number of patent application 201020285750.5) and forms; Thermal insulation layer is a pearlstone; Skin is a furnace shell.Locate to be provided with the air outlet on the upper side at the middle part, slag-drip opening is arranged at the bottom, there is coal-fired gasification furnace deslagging sealing cover at the slag-drip opening place (to declare the utility model patent technology, name is called coal-fired gasification furnace deslagging sealing cover), gasifying medium enters pipe, gasifying medium enters the pipe outer end and connects gas blower, the inner plate with oxygen that connects, plate with oxygen has two kinds of mini-coal-fired gasification furnace plate with oxygen (number of patent application 201020285757.X), pocket coal-fired gasification furnace plate with oxygens (number of patent application 201020285752.4) according to the size of user's gas consumption.Coal-fired by top adding burner hearth, by artificial control oxygen-supplying amount, air is distributed in bottom of furnace body equably via plate with oxygen, ash bed and contacts with the coal seam, make it anoxycausis after heating, mixed gas arrives hollow layer behind process zone of oxidation, reducing zone, destructive distillation layer, drying layer, discharges burner hearth by the air outlet.
The beneficial effects of the utility model are coal-fired through after this coal-fired gasification furnace gasification; can solve the coal-fired problems such as the environmental pollution that is brought weighs, thermal losses is high, waste of fuel is bigger, fuel availability is low of directly burning effectively in utilization; save the mass-producing gas station simultaneously and lay the work of gaspipe network; gas station compares with mass-producing; the characteristics that it is with low cost, easy to use, use range is wider, have more handiness are particularly outstanding, are more suitable for the use in individuality.
