Problems solved by technology

In response to this problem, some experts proposed to set up a separate telephone, such as the electric ignition device at the bottom of the gasifier disclosed in Chinese Patent Application No. CN200720146012. The advantage of this method is that it solves the ignition problem, but it also directly increases the biomass gasification. cost
[0006] Furthermore, some gasification furnaces suffer serious heat loss during operation, which includes several aspects. First, the wall insulation of the gasification furnace is not enough; second, the sensible heat loss of ash discharge is serious; serious loss

Embodiment Construction

[0033] see below figure 1 , the outer wall 4 of the gasification furnace is an upright cylindrical structure, and its internal structure is composed of a retort chamber 1 in the upper section, a main gasification chamber 2 in the middle section, and an ash chamber 3 in the lower section. The grate 18 is divided.

[0034] The retort chamber 1 is surrounded by a circular outer wall 4 and an upper insulation layer 8 , with an end cover 6 on the top, and a water seal ring groove 5 outside the upper part of the outer wall 4 .

[0035] The main gasification chamber 2 is composed of a radiation cylinder 13, a heat conduction cylinder 14, a lower insulation layer 22 and an outer wall 4 from inside to outside in the radial direction, and encloses two annular spaces. On the side wall of the furnace body at the upper part of the main gasification chamber 2, an air inlet 11 penetrating through the lower insulation layer 22 is set; on the upper side wall of the radiant cylinder 13, a gas ...

Abstract

The invention discloses a household up-draft biomass gasification device, which has an upright cylinder structure and is characterized in that the household up-draft biomass gasification device comprises a destructive distillation chamber arranged at the upper section thereof, a main gasification chamber arranged at the middle section thereof and an ash chamber arranged at the lower section thereof; all the sections are respectively separated by a heat storage grille and a heat storage grate; and the main gasification chamber is enclosed by a radiation cylinder on the periphery. The household up-draft biomass gasification device has no need of an external firing heat source, fast firing speed and high temperature of the gasification center, remarkably reduces tar content, reduces radiation loss of a furnace body, and has high gasification efficiency, long fire banking time of the gasification furnace, simple and compact structure, convenient operation and low operating cost.

Description

technical field [0001] The invention relates to a gasification device, in particular to an updraft household biomass gasification device. Background technique [0002] China is a large agricultural country with abundant crop straw resources. However, due to the low level of comprehensive utilization of straw, a considerable amount of crop straw is discarded in the field. During the harvest season, the phenomenon of setting fire to straw in farmland can be seen everywhere. This not only caused a great waste of resources, but also caused serious pollution to the atmospheric environment due to the smoke from straw burning, and also became a hidden danger of fires, traffic accidents, and burning of wires and communication cables. Therefore, it is of great significance to popularize biomass fuel gasifiers in rural areas. It not only turns waste into wealth, but also solves the problem of environmental pollution and improves people's quality of life. In addition, it saves energy a...
