Household straw gasification furnace

Abstract

The invention relates to a novel household straw gasification furnace which comprises a pressure device, a flange used for fixing a screw rod, a deashing and decoking block device and a large furnace tooth, a small furnace tooth, a water circulation heating device and a gas-fired boiler of the water circulation heating device, wherein the structure of the pressure device is as follows: a sleeve is sleeved between a first bevel gear and the flange, the first bevel gear and the upper end of the pressure screw rod are fixedly connected, a second bevel gear is fixedly connected with one end of a rocker shaft, and the first bevel gear and the second bevel gear are mutually meshed; and a bearing is arranged behind the second bevel gear on the rocker shaft, the bearing is supported by a bearing base fixed on a furnace top cover, and the other end of the rocker shaft is connected with a rocker. The novel household straw gasification furnace provided by the invention has the advantages that the operation is more simple and convenient through each structure improvement and reconstruction, the using effect is more ideal and stabilized, the thermal efficiency is improved further, thereby also establishing a foundation for realizing automatization.

Description

technical field [0001] The invention relates to a household type straw gasification furnace, in particular to a pressurization, ash cleaning, coke removal and water circulation heating device therein. Background technique [0002] Household straw gasifiers have gone through a period of frenzied research and development and sales. Since most people mainly imitate them, they have not carefully studied and solved the guarantees of feeding, pressurization, dust cleaning, coke removal and tar treatment. Many problems in normal use have been gradually eliminated by the market. The patent application number is 2009201439351.1. Although it has the structural functions of pressurization, dust removal, and coke removal, it solves the problem of easy formation of cavities in the gasification process of household straw gasifiers. , the problem of deviation, but the filling and ash removal must be carried out under the condition of shutdown and there is no tar treatment device, which wil...

[0002] Household straw gasifiers have gone through a period of frenzied research and development and sales. Since most people mainly imitate them, they have not carefully studied and solved the guarantees of feeding, pressurization, dust cleaning, coke removal and tar treatment. Many problems in normal use have been gradually eliminated by the market. The patent application number is 2009201439351.1. Although it has the structural functions of pressurization, dust removal, and coke removal, it solves the problem of easy formation of cavities in the gasification process of household straw gasifiers. , the problem of deviation, but the filling and ash removal must be carried out under the condition of shutdown and there is no tar treatment device, which will cause tar to block the pipe network, and there will be peculiar smell after the stove and combustion, and the gasification medium air cannot be added after the coke is formed. And the problem of secondary pollution of the environment due to tar leakage

After that, the patent application number is 201020157190.5, and the 2009201439351.1 patent is optimized and equipped with a feeding device, so that the filling can be carried out without stopping the furnace, and the duration of the fire can be extended arbitrarily, ensuring a large amount of long-term gas consumption for heating and greenhouse heating. The 201110136802.1 patent is equipped with a tar treatment and furnace combustion device for the above-mentioned patent, which solves the problem of tar blocking the pipe network, odor generation after the stove and combustion, and secondary pollution of the environment due to tar leakage, but it is still not easy to operate. Convenient and labor-intensive, especially when the material is wet, gas cannot be produced normally, the use effect is unstable, the removal of coke is not fast and thorough, and the heat utilization is not sufficient. For example, when the smoke generated by combustion is discharged, its heat is lost in vain and not used. ; The degree of automation cannot be realized
