Abstract

The utility model relates to a straw gasifier which belongs to the technical field of the design and manufacturing of small straw gasifiers for rural households. The straw gasifier comprises a burning furnace and a purifier. A closed drain hopper is arranged above the burning furnace. An upper cover is arranged above the drain hopper. The upper part of a gas outlet pipe is provided with an exhaust duct. The exhaust duct is provided with an exhaust valve. The rear part of the exhaust valve is provided with an exhaust fan. The straw gasifier is characterized in that when the straw fuel is burned and consumed to a certain amount, the upper cover is opened to continue to feed, at this time, the exhaust fan is opened, so that the flue gas is exhausted through the gas inlet pipe, and in addition, the flue gas cannot be released indoors because of the separation of the closed drain hopper. The straw gasifier has the advantages of simple structure and reasonable design, solves the actual problem of the prior product that plenty of flue gas is released indoors when the fuel is added, and ensures that the indoor air is fresh.

Description

A kind of stalk gasifier

Technical field

The utility model belongs to design and the manufacturing technology field of rural households with miniature stalk gasification furnace.

Background technology

The stalk gasifier of using in rural households at present, owing to exist on structure design, very undesirable during use, exactly when dosing stalk fuel, the flue gas in the roasting kiln all is released to indoor, causes indoor serious atmospheric pollution.Destroy IAQ (indoor air quality).Therefore say that present employed stalk gasifier is not very desirable.

Summary of the invention

The purpose of this utility model provides and a kind ofly can not produce flue gas when dosing stalk fuel and be released to indoor stalk gasifier, to solve the problem that currently available products exists.

Structure of the present utility model as shown in drawings; Constitute by roasting kiln and cleaner.One roasting kiln inner bag is arranged in roasting kiln.Between roasting kiln and roasting kiln inner bag, form a water cavity.One sealing feed leakage bucket is arranged on roasting kiln.One loam cake is arranged on feed leakage bucket.One upper hose is arranged at the top in roasting kiln one side.The water pipe once in the bottom of roasting kiln one side.On a side of roasting kiln, a cleaner is arranged.One cleaner inner bag is arranged in cleaner.On the top of cleaner one water-in is arranged.In the cleaner bottom one cleaner water discharge valve is arranged.One cleaner inner bag water discharge valve is arranged in the bottom of cleaner inner bag.Between roasting kiln inner bag and cleaner inner bag, have gas inlet pipe.One combustion gas escape pipe is arranged on the cleaner inner bag.On the combustion gas escape pipe, have the combustion gas pipe valve.On the top of combustion gas escape pipe one exhaust duct is arranged.Have exhaust valve on the exhaust duct.At the rear portion of exhaust valve one exhaust blower is arranged.In the bottom of roasting kiln one oxygen supply pipe is arranged, one gas blower is arranged at the oxygen supply tube end.On the oxygen supply pipe, have roasting kiln oxygen supply valve and combustion gas oxygen supply valve.Oxygen supply pipe, combustion gas escape pipe and exhaust duct are interconnected.Open and close by each valve control during use.Use of the present utility model is that upper hose and return water pipe are connected in the water inlet and rising pipe of radiator.The combustion gas escape pipe is received the gas furnace air inlet to be chewed.Water cavity between roasting kiln and the roasting kiln inner bag is filled with water.Water will be filled with in the cleaner.Its method of work is: stalk is cut into broken section, inserts the roasting kiln inner bag.Again fuel is tamped, to increase density.Ignite from the bottom of furnace body igniting.By the gas blower oxygen supply.The flue gas that burning produces enters the cleaner inner bag through gas inlet pipe, and flue gas is met and cold aqueous vapor in the flue gas is agglomerated on the inwall of cleaner inner bag by the cleaner inner bag time.Flue gas after being purified has become inflammable gas this moment, delivers on the gas stove by the combustion gas escape pipe, lights and can use.When stalk fuel is depleted to when a certain amount of through burning, to open loam cake and continue filler, open exhaust blower this moment, and flue gas is discharged through gas inlet pipe, seals the obstruct of feed leakage bucket in addition, and flue gas can not be released to indoor.When treating that stalk fuel fills up, close exhaust blower again.Continue to use.This product is to utilize biomass material to heat under anoxic condition to react the characteristics design manufacturing that energy can be transformed.When stalk fuel burns, supply a spot of oxygen, make carbon, hydrogen in the flue gas generate inflammable gass such as carbon monoxide and methane.By cleaner dust in the inflammable gas and tar etc. are purged and can use.Owing to have closing funnel and loam cake and exhaust blower, make that not having flue gas when dosing stalk fuel is released to indoorly, has kept the quality of room air on the roasting kiln of the present utility model.Solved the practical problems that currently available products exists.
