Abstract

The utility model relates to a hot-air type straw gasifying furnace which relates to the improvement of a crop straw burning furnace. The hot-air type straw gasifying furnace is characterized in that a sealed air inlet chamber is sleeved on the periphery of the lower part of a furnace body, the internal space of the furnace body is communicated with an air inlet chamber by air inlets, a sealed hot water tank is sleeved on the periphery of the upper part of the furnace body, the upper part of the furnace body is provided with a mixed fuel-gas outlet pipe communicated with a purifying filter, an air inlet pipe is respectively communicated with the air inlet chamber and the purifying filter, and the mixed fuel-gas outlet pipe is provided with a waste-gas exhausting port. The utility model has the following advantages: after the straw combustible is fed and ignited, the furnace can continuously combust and supply air until the straw combustible in the furnace body is completely combusted, the combustion is not required to be stopped when the fuel gas is not required; the structural design is simple and reasonable, and the utilization is convenient; and compared with that of the common fuel-gas producing furnace, the gas yield of the hot-air type straw gasifying furnace is increased by 15 percent to 20 percent.

Description

The hot air type stalk gasifier

Technical field

The utility model boiler technology field relates to a kind of improvement of agricultural crop straw burner.

Background technology

At present, still with act as a fuel cook food or warm oneself in the majorityly of agricultural crop straw, its deficiency is that efficiency of combustion is low, wastes time and energy, and environment is polluted seriously in vast rural area.Also have stalk class farm crop by producing biogas as the energy, its advantage is to use totally, convenient, and environmentally safe, waste also can be used as the fine green fertilizer, but deficiency is that the system gas time is long, and system gas need be subjected to temperature limitation, and gas producing technology requires height.

Summary of the invention

The purpose of this utility model is:

A kind of hot air type stalk gasifier is provided, stalk is made combustion gas by vapourizing furnace.

The technical solution of the utility model is:

Be with airtight inlet plenum in periphery, body of heater bottom, be communicated with by air inlet port with inlet plenum in the body of heater, be with airtight hot well tank in the upper of furnace body periphery, there is the air mixture that is communicated with polishing filter to go out pipe in upper of furnace body, air intake duct is communicated with inlet plenum and polishing filter respectively, goes out to be provided with Waste gas outlet on the pipe in air mixture.

The beneficial effects of the utility model are:

This stove can be after having added stalk fuel, igniting back continuous burning air feed, and till stalk fuel finishes in body of heater, when not needing combustion gas, also need not cutoff, and the structure design advantages of simple, easy to use, and than common system gas furnace raising gas production rate 15-20%.

Description of drawings

Fig. 1 is the utility model structure iron;

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1, the 1st, air inlet port, the 2nd, inner lining of furnace, the 3rd, inlet plenum, the 4th, hot water outlet, the 5th, body of heater, the 6th, hot well tank, the 7th, hot water inlet, the 8th, sealing cover, the 9th, air mixture goes out pipe, the 10th, Waste gas outlet, the 11st, Waste gas outlet valve, the 12nd, polishing filter inlet pipe, the 13rd, gas outlet, the 14th, polishing filter, the 15th, polishing filter discard solution discharge port, the 16th, air inlet tube valve, the 17th, polishing filter inlet pipe valve, the 18th, air intake duct, the 19th, blower fan.

Vapourizing furnace before use, sealing cover (8) is opened, in stove, add stalk, after the igniting, build sealing cover (8), be in sealed state in the stove, blower fan (19) is by air intake duct (18), inlet plenum (3), air inlet port (1) is blown in body of heater (5), make stalk sustained combustion in body of heater (5), produce carbon monoxide and carbonic acid gas by burning, the gas that initial combustion produces is opened Waste gas outlet (10) earlier and is emitted, after treating flameholding, close Waste gas outlet (10), air mixture goes out pipe (9) by air mixture and sends in the polishing filter (14) after filtration, and with the air mixed that polishing filter inlet pipe (12) enters polishing filter (14), send use from gas outlet (13) then.Owing to when gas generation and combustion, can produce a large amount of heat energy in the body of heater (5), therefore, add a cover hot well tank (6) at body of heater (5), heat energy can be obtained to make full use of.

Claims

1, a kind of hot air type stalk gasifier, it is characterized in that: be with airtight inlet plenum in periphery, body of heater bottom, be communicated with by air inlet port with inlet plenum in the body of heater, be with airtight hot well tank in the upper of furnace body periphery, there is the air mixture that is communicated with polishing filter to go out pipe in upper of furnace body, air intake duct is communicated with inlet plenum and polishing filter respectively, goes out to be provided with Waste gas outlet on the pipe in air mixture.
