Description

Reverse-flow gasification direct-combustion cooking hot water straw fuel gas stove

Technical field, the utility model relate to the reverse-flow gasification direct-combustion cooking hot water straw fuel gas stove of a kind of regenerative resource and favourable cleaning ambient.

Background technology, straw fuel gas stove kind is more at present, can divide following two classes: a class is that the gasification still gasifies combustion gas and lead to the stove and accessory burning through cooling, after filtering, the still that gasifies must impel partly with the electric fan blowing, and crushing straw spontaneous combustion generation heat energy impels all the other crushing straws gasification generation fuel gas to lead to the stove and accessory burning, produce tar, contaminated environment, blocking pipe in the combustion gas circulation, for preventing that carbon monoxide from overflowing poisoning, the gasification still will singly be put a room.Complex structure, the cost height must be used power supply, contaminated environment, shortcoming safety; Another kind of is to be burner on the gasification still, combustion gas is directly burnt, the gasification still all around is a fresh air inlet, impels partly crushing straw spontaneous combustion to produce heat energy by the fresh air inlet natural air inlet and impels all the other crushing straws to be gasificated into fuel gas for burner flame, and stalk itself hinders air and enters to the flame infiltration combustion-supporting, therefore the crushing straw flame of spontaneous combustion easily extinguishes, stalk becomes the black charcoal, smolders, and the output combustion gas is few, the thermal efficiency is low, and contaminated environment.

Summary of the invention, the utility model are to overcome above-mentioned deficiency, and a kind of reverse-flow gasification direct-combustion cooking hot water straw fuel gas stove of new-type furnace binding is provided.

The utility model is to realize like this, reverse-flow gasification direct-combustion cooking hot water straw fuel gas stove is to constitute by three sections: hypomere is reverse-flow gasification still, folded the dropping on the base of cylinder empty in the middle of being constitutes, dress crushing straw in the middle of the middle empty cylinder, light the burning of this crushing straw by lighting-up tuyere and produce heat energy and more most of all the other crushing straws are gasificated into fuel gas, these fuel gas and the flame socket by the top enters burner and becomes flame.Because the combustible gas that gasification is come out directly burns without any processing, so claim direct combustion.The stalk flame that lighting-up tuyere is lighted be by the center to external diffusion, and the fuel gas that is gasificated into is to assemble burning by the center that flows to outward, therefore is called reverse-flow gasification.Middle empty cylinder is the two-layered steel plates welding fabrication, the splendid attire water still water jacket that claims to gasify between two-layer, water in the gasification still water jacket absorbs the waste heat that the crushing straw gasification produces, water inlet pipe is arranged at gasification still water jacket bottom, the top water outlet enters the burner water jacket, base has the ash door, grate, arm-tie, the arm-tie outlet, handle location retaining, on grate, install and reverse-flow several vent stacks of gasification still equal height, every vent stack has a lot of holes, air below the grate is the infiltration of the crushing straw in reverse-flow gasification still through the hole on the vent stack, impels the crushing straw burning to produce heat energy and impels crushing straw gasification fuel gas again.Below grate, adorn an arm-tie, the same position of identical size with the vent stack number corresponding arm-tie air vent is fully arranged on the arm-tie.By pulling handle location retaining make the arm-tie air vent overlaps with the bottom outlet of vent stack, partially overlap, completely wrong, air intake is big during coincidence, the interior crushing straw gasification burning of reverse-flow gasification still is many, flame is strong.Air intake is few when partly overlapping, and the crushing straw gasification burning is few in the reverse-flow gasification still, a little less than the flame, how much how much controls the crushing straw gasification burning, the flame power with what two holes overlapped.The completely wrong position of vent stack bottom outlet and arm-tie air vent, the vent stack shutoff, air intake not, the fray-out of flame banking adds crushing straw in order to stand-by by dog-house.The vent stack bottom outlet overlaps with the arm-tie air vent again, and flame is resume combustion again.The stage casing is a burner, and fuel gas and flame that the reverse-flow gasification still of hypomere is produced burn fully at burner.Air vent is arranged at the burner bottom, and air enters burner and combustion gas mixing by these holes; Hole pattern is arranged at the top at burner, promptly is drilled to aperture with sheet metal, and these holes are with equidistant arrangement, and air enters burner by hole pattern, and fuel gas is burnt into flame fully.The outside of burner is burner water jacket, conduction heat and the radiant heat that absorbs burner flame, and burner water jacket water inlet pipe and following gasification still water jacket are communicated with; Burner outlet pipe and top heat dump water jacket are communicated with.Burner is folded to be dropped on the reverse-flow gasification still, is inserted in the socket of reverse-flow gasification still.Epimere is a heat dump, the flame of burner rises to heat dump, heat dump is a heat dump water jacket, the central space of heat dump water jacket is adorned several perpendicular heat absorption transverse tubes, the heat energy of flame absorbs conduction heat and radiant heat in the water in the water jacket by heat dump water jacket central space and heat absorption transverse tube, and heat dump can be designed to other version as required.The water inlet pipe of heat dump water jacket is communicated with the burner water jacket, uses soft pipe connection.Outlet pipe with hot facility soft pipe connection.Gasification still water jacket, burner water jacket, heat dump water jacket, with hot facility formation hot water cyclesystem.As heat dump is shifted out the burner outside when doing the cooking thermal source.Connecting with flexible pipe is very easily.On reverse-flow gasification still, be equipped with bracing frame, to support heat dump or cooker.

The beneficial effects of the utility model are that the utility model compared with prior art has following advantage:

1, the reverse-flow gasification direct-combustion cooking of the utility model hot water straw fuel gas stove is combustion-supporting by vent stack air intake on the grate of reverse-flow gasification still base, it is smooth and easy to ventilate, the slap-up combustion gasification of crushing straw of reverse-flow gasification still dress, burn till till the ashes, the flame that burner is emerged is uninterrupted, there is not cigarette, not flavor.

2, the outlet of the arm-tie under the reverse-flow gasification still of the utility model base grate is equipped with arm-tie, by the handle location retaining of arm-tie arm-tie is pulled out inserted mode and how much control reverse-flow gasification still air intake, gasification burning amount size, the flame power, but banking adds crushing straw again, and knock down the flame recovers burning again.

3, the reverse-flow gasification still of the utility model is gasificated into the tar that produces in the gas process at crushing straw and is incinerated by flame, and tar originally is harmful substance, and burning becomes heat energy.

4, the utility model is fit to the various fuel of burning, and various straws, sawdust, wood shavings, wormwood artemisia, leaf, dried cow dung etc. are only required and pulverized all incendivities.

5, the utility model can be done cooking thermal source and manufacture hot water's heating, and the heat energy with burner flame conduction and radiation in reverse-flow gasification still gasification is absorbed by the water in the water jacket entirely, and heat energy makes full use of, thermal efficiency height.

6, the combustion gas that produces of the reverse-flow gasification still of the utility model is directly burnt into flame and is claimed direct combustion in burner, and the combustion gas consumption of calorie of not lowering the temperature is directly to burn in the condition of high temperature, and heat energy not loss makes full use of.
