Description

A kind of energy-saving environment-friendly gasification stove

Technical field

The utility model relates to a kind of high-performance bio energy inflammable gas generator, belongs to the gasification furnace field.

Background technology

In agricultural production process, a large amount of bioenergy material production is arranged, as the stalk of crops, the discarded culture materials (bacterium rod) that the Edible Fungi process produces etc., be effective bioenergy material.These material parts act as a fuel and burnedly fall, and a part is used for fertilizing the soil as field material also.But because of in above-mentioned two kinds of occupation modes, existing the too low problem of utilization benefit, cause also having a large amount of agricultural crop straws to be discarded in the field, cause the waste of a large amount of bioenergy materials on the one hand, also caused of the biological pollution of these energy and materials on the other hand the Nature.In order to improve these bioenergy utilization efficiency of material, China's utility model patent 01221595.3 discloses a kind of " high-efficiency energy-saving straw gasification furnace ", it is being raw material through broken stalk such as straw, wheat straw, cornstalk, husk, peanut shell, wood shavings etc., processes such as the pyrolysis of process gasification furnace, oxidation produce fuel gas such as methane (CH4), hydrocarbon, carbon monoxide and organic volatile, use for cooking.This utility model patent is made of body of heater, internal furnace, gas-purification cooler, gas burner.Internal furnace is the reverse taper of being made by steel plate, be loaded in the body of heater, grate is equipped with in its lower end, around above grate omits 10 uniform warm braw air inlet pipe are arranged, body of heater middle and lower part skin is equipped with heat-insulation layer, is boiler around the upper of furnace body, the body of heater top is charge door and manhole cover, upper of furnace body one side has gas outlet, links to each other with the combustion gas efferent duct, and the gas-purification cooler is that a hollow cylinder is connected with body of heater, gas burner respectively.Since this utility model proposed a kind of by after bioenergy is gasified again for the equipment scheme of burning, making with the agricultural crop straw is that the utilization ratio of the bioenergy of representative improves greatly.Yet, because crop material class bioenergy material is the very complicated macromolecular compound of molecular structure, in the high-temperature gasification process, can produce a kind of tar class material, establish gas outlet what this technical scheme adopted in upper of furnace body, be connected to the gas-purification cooler by the combustion gas efferent duct, enter by the fuel gas behind the high-temperature gasification that the cooling along with gas is condensed into tar behind the gas-purification cooler, old long-pending in the gas-purification cooler, or discharge, form a kind of pollution new to environment.

The utility model content

The purpose of this utility model is that by improving the connected mode of gas-purification cooler and body of heater, formed tar reenters combustion chambers burn when making cooling, to alleviate a kind of new technical scheme of tar to ambient influnence.

The utility model is realized by following manner:

A kind of energy-saving environment-friendly gasification stove, by body of heater, be installed on the grate of body of heater lower end, be installed on the air inlet pipe on the sidewall of grate top, the air accumulator of body of heater top constitutes, be provided with the back taper furnace wall of making in the body of heater by steel plate, by the back taper furnace wall body of heater inside is separated into two parts, it on the furnace wall vaporizer, it under the furnace wall water cooling chamber, the body of heater top is provided with charge door and manhole cover, upper of furnace body one side has gas outlet, link to each other with gas storage tank, the body of heater two side is respectively equipped with water inlet pipe and outlet pipe, it is characterized in that also being provided with the tar return duct in the bottom of air accumulator.

Also be provided with baffle plate in the described air accumulator.

Because the utility model can solve the tar pollution problem that common gasification furnace produces in gasification at bioenergy effectively, and product structure is simple, reasonable in design, can realize the purpose of energy-saving and environmental protection effectively, easy to operate, for production, living needses such as the steaming that solves rural households, burning, bakings, in particular for boiling required in the Edible Fungi, sterilization, and process such as product oven dry provides good joint bavin, the energy device of economizing on coal, and adapted to energy conservation and environment protection.
