Abstract
The utility model relates to a negative pressure firing straw gasification furnace, which comprises a furnace body. A furnace cavity is arranged in the furnace body, a feeding opening is positioned above the furnace cavity, a sealing furnace cover is arranged on the feeding opening, a side gas outlet pipe is positioned at the upper part of the furnace body, a sealing furnace door is arranged at the lower part of the furnace body, a furnace grate is positioned at the bottom of the furnace cavity, a side air intake pipe is positioned under the furnace grate, a purifier is connected to the side gas outlet pipe on the furnace body and is provided with a casing body, an inlet and an outlet which are communicated with the casing body are arranged on the casing body, a filtering medium is filled between the inlet and the outlet of the casing body, an outlet valve is connected with the outlet of the purifier, an air blower is connected with the outlet valve, the inlet of the air blower is connected with the outlet valve, and the outlet of the air blower is connected with the inlet of the gas furnace through a valve. When the air blower rotates, the valve can be adjusted so that the straw in the furnace cavity can burn under the condition without oxygen, the straw burns under the condition without oxygen to generate flammable fuel gas which mainly contains carbon monoxide, and the air blower can suck the fuel gas and feed the fuel gas into the gas furnace for burning. The utility model can operate under the condition with negative pressure, the flammable fuel gas generated during the operation of the furnace cannot easily leak, the operation is safe, and the environment can not be polluted.
Description
Technical field
The utility model relates to the blower fan of a kind of stalk gasifier, particularly a kind of stalk gasifier.
Background technology
Stalk gasifier is to allow the interior agricultural crop straw of burner hearth burn under the condition of anoxic, produces the flammable combustion gas based on carbon monoxide, and the combustion gas of generation can be used for culinary art, heating with the gas furnace burning.Easy to use, the health of stalk gasifier, fuel availability is higher, and the thermal efficiency is higher, and environmental pollution is few.Stalk gasifier has body of heater, burner hearth is arranged in the body of heater, and there is charge door the top of burner hearth, and the sealing bell is arranged on the charge door, upper of furnace body has the side escape pipe, the body of heater downside has sealing door, and burner hearth bottom has fire grate, and the side blast pipe is arranged under the fire grate, the side escape pipe of upper of furnace body is connected with smoke exhaust pipe through exhaust smoke valve, body of heater upside escape pipe also is connected with clarifier through air outlet valve, and clarifier has housing, between the import and export in the housing filter medium is arranged.In the prior art, the blast pipe of stalk gasifier is connected with blower fan by main air valve.This stalk gasifier is worked under barotropic state, during work, in the burner hearth, in the clarifier and be at barotropic state in the pipe fitting, the flammable combustion gas that produces when stalk gasifier is worked under positive pressure is revealed easily, combustion gas is revealed influences environment in use, also is a kind of unsafe factor.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose the negative-pressure firing stalk gasifier that a kind of flammable combustion gas that produces in use is not easy to reveal.
The utility model is realized with the following method.
The negative-pressure firing stalk gasifier has body of heater, burner hearth is arranged in the body of heater, there is charge door the top of burner hearth, the sealing bell is arranged on the charge door, upper of furnace body has the side escape pipe, the body of heater downside has sealing door, burner hearth bottom has fire grate, and the side blast pipe is arranged under the fire grate, and the side escape pipe of upper of furnace body is connected with smoke exhaust pipe through exhaust smoke valve, body of heater upside escape pipe also is connected with clarifier through air outlet valve, clarifier has housing, and advancing of communicating with housing arranged on the housing, advancing in the outlet, housing, filter medium is arranged between the outlet, the outlet of clarifier is connected with blower fan, and the inlet of blower fan links to each other with the outlet of clarifier.
During use, the outlet of blower fan is linked to each other with the air intake of gas furnace by valve, when blower fan rotates, can suck burner hearth to combustion air through side blast pipe of the present utility model, stalk in the burner hearth is burnt under negative pressure state, and control valve can make the stalk in the burner hearth burn under the condition of anoxic, stalk burns under the condition of anoxic and produces flammable combustion gas based on carbon monoxide, but blower fan sucking-off combustion gas is sent into gas furnace and burnt.
The utility model can be worked under negative pressure state, and the flammable combustion gas that produces during work is not easy to reveal, and is safe in utilization, do not influence environment.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 cuts open schematic diagram according to the master office of looking of the stalk gasifier of invention scheme proposition of the present utility model;
