Description

Technical Field

[0001] The utility model belongs to the field of solid waste treatment, and in particular relates to a continuous gas production device. Background Art

[0002] The comprehensive utilization of waste rubber and plastic scraps and straw resources not only solves the problem of environmental pollution, but also realizes resource recycling, which is of great significance. Waste rubber and plastic scraps, organic matter, and biomass gasifier is a device that converts waste rubber and plastic scraps, organic matter, and biomass materials into fuel oil and combustible gas. Its working principle is to put waste rubber and plastic scraps, organic matter, and biomass materials into the gasification generator, and decompose the waste rubber and plastic scraps and biomass materials into fuel oil and combustible gas under high temperature and oxygen deficiency conditions, mainly including carbon monoxide, hydrogen and methane.

[0003] The working principle of the gasification generator of waste rubber and plastic scraps, organic matter, and biomass can be divided into three stages: the first is the drying stage, the second is the pyrolysis stage, and the third is the gasification stage. In the drying stage, the water in the waste rubber and plastic scraps, organic matter, and biomass materials is evaporated, so that the moisture content of the biomass materials is reduced, creating conditions for the subsequent pyrolysis and gasification. In the pyrolysis stage, the waste rubber and plastic scraps, organic matter, and biomass materials are decomposed into three substances: solid, liquid, and gas at high temperature. Among them, the solid substance is mainly charcoal, the liquid substance is mainly fuel oil, and the gas is mainly carbon monoxide, hydrogen, methane and other combustible gases. In the gasification stage, the solid and liquid substances in the waste rubber and plastic scraps, organic matter, and biomass materials are further decomposed into fuel oil and combustible gas. The mixed oil produced by the waste rubber and plastic scraps, organic matter, and biomass can be used as fuel oil, and the combustible gas can be used in power generation, heating, heat treatment, civil fuel and other fields. However, the existing gasification generators of waste rubber and plastic scraps, organic matter, and biomass still have the problems of poor gas quality and potential safety hazards.

Based on the embodiments provided by the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] The utility model provides a continuous gas production device. Figure 1 Schematic diagram of the structure of the continuous gas production equipment according to the embodiment of the utility model. Figure 1 As shown, the continuous gas production equipment at least includes a gas generating device 1, such as Figure 2 As shown, the gas generating device 1 further includes a shell 11 and a distributor; the distributor further includes a transmission disc 121, a distribution member 122, and a driving member 123; the shell 11 is vertically arranged, and the inner surface thereof encloses a reaction chamber; the transmission disc 121 is horizontally arranged above the interior of the reaction chamber, and its shape and size are adapted to the horizontal cross-section of the reaction chamber, gears are circumferentially arranged on the edge of the rotating disc, and a plurality of drop-off openings are evenly opened on the inner side of the gears on the rotating disc; the distribution member 122 includes a shaft fixedly connected to the bottom of the transmission disc 121, and a spiral blade sleeved outside the shaft; the driving member 123 is arranged on the outer side of the shell 11, and drives the transmission disc 121 to rotate through gears. The continuous gas production equipment realizes that the material entering the reaction chamber is first evenly distributed under the action of the transmission disk 121 through the design of the structure of the gas generating device 1. At the same time, under the action of the distribution member 122, the material is evenly distributed layer by layer on the entire cross-section of the reaction chamber by the spiral blades, so that it is strictly sealed and reacts in the reaction chamber. At the same time, the reaction of the internal material layer does not form voids, ensuring that there is no convection between the gas generated in the furnace and the external air, which not only ensures the safety of the process but also improves the gas quality.

[0024] It should be noted that the gas generation process of the gas generating device 1 is a process of continuous drying, dry distillation, and reduction gasification.
