Description
Technical field
The utility model belongs to clean energy resource comprehensive utilization technique field, is specifically related to a kind of heat accumulating type biogas utilization device.
Background technology
Biogas is the lower fuel gas of a kind of calorific value, because the development of technology and the demand of new forms of energy, biogas has become increasingly extensive new forms of energy.No matter be that which kind of mode of utilization produces fuel gas with technology; No matter also its scale that produces biogas has much; It all is the tank body that directly is linked into biogas after treatment through pipeline a special stored-gas that biogas in the past stores, because the difficulty of biogas compression is bigger, so; Such storage facility volume is generally all huger; Tank body itself have huge inflammable and explosive danger, whole pipe also has leaks and dodges quick-fried risk, the management difficulty of system's security of operation will increase with investment greatly.
Summary of the invention
The purpose of the utility model provides a kind of heat accumulating type biogas utilization device that need not to carry out the biogas storage, and the heat energy that storage biogas burning back produces also is used.
The technical scheme that the utility model adopted is:
A kind of heat accumulating type biogas utilization device includes biogas generating device, the dry knot screen of biogas and biogas burner, it is characterized in that:
Be connected with the dry knot screen of biogas, biogas burner and regenerative apparatus on the described biogas generating device in turn.
Be added with heat-storing material in the described regenerative apparatus, include zeolite, foam metal and calcium chloride.
In the described heat-storing material, calcium chloride is filled in the cavity of foam metal particle.
Described foam metal is foam copper or foamed aluminium.
The utlity model has following advantage:
The utility model is not provided with the biogas memory device in the biogas comprehensive utilization flow process; But biogas generating device, biogas dry knot screen, biogas burner are set and include the regenerative apparatus of zeolite, foam metal, calcium chloride; The heat energy that biogas burning back is produced also is used, and has not only avoided the danger of storage biogas, has reduced the volume of each equipment in the comprehensive utilization flow process; And heat storage efficiency is high, has improved the comprehensive utilization ratio of biogas and has utilized security.
Description of drawings
Fig. 1 is the structure flow chart of the utility model.
Among the figure, 1-biogas generating device, the dry knot screen of 2-biogas, 3-biogas burner, 4-regenerative apparatus.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is carried out detailed explanation.
A kind of heat accumulating type biogas utilization device that the utility model is related connects the dry knot screen 2 of biogas, biogas burner 3 and regenerative apparatus 4 successively on biogas generating device 1; Be added with heat-storing material in the regenerative apparatus 4, include zeolite, foam metal and calcium chloride, the volume adding proportion of its mesolite is 30～90%, and the volume adding proportion of foam metal is 10～70%, and calcium chloride is filled in the cavity of foam metal particle; Foam metal can be foam copper or foamed aluminium.
The biogas that produces in the biogas generating device 1 is earlier through the dry knot screen 2 of biogas; Dehumidify and removal of impurities; After having improved methane purity; Be input to biogas burner 3 and burn, after the heat energy that burning produces is absorbed by the heat-storing material in the heat energy regenerative apparatus 4, can carry out follow-up heat energy release and utilization.Owing to introduced regenerative apparatus 4; Make whole biogas comprehensive utilization flow process that basic transformation take place; Biogas to all generations need not pass through any pressurized storage, but directly burning, the thermal energy storage that produces burning is in heat-storing material; The thermal storage density of heat-storing material is high, has dwindled the volume of equipment greatly.
Zeolite, foam metal and calcium chloride all are good heat-storing materials.Zeolite has very huge application potential, in the process of its dehydration, can store a large amount of heat energy, otherwise in the process of its suction, can emit a large amount of heat energy again; The foam metal that development in recent years is come out such as foam copper and foamed aluminium etc. are a kind of new section bars with good thermal conductivity, and its internal voids rate is high, has kept the good characteristics of metal fever conductibility, and the material that can be used as the heat transfer efficiency that improves regenerative apparatus uses; Simultaneously, it is big that foam metal has under the same volume dutycycle, lightweight characteristics.Calcium chloride is a kind of inorganic salts, also is a kind of material of accumulation of heat, the accumulation of energy characteristics of accumulation of heat when having suction heat release and dehydration drying; Under the same volume; The characteristic index of calcium chloride accumulation of heat is not as zeolite, but solubilized is the aqueous solution, can easily it be filled in the internal cavities of foam metal; Method is that the foam metal particle is dipped in the calcium chloride solution; This calcium chloride solution is anhydrous calcium chloride complete lysigenous saturated solution in boiling water, and the particle that stays after the foam metal particle of submergence and calcium chloride solution are sieved carries out water evaporates, till fully the water evaporation being done; The largest benefit of adding this material is exactly under the condition of not losing heat transfer, to increase the accumulation of heat volume to greatest extent.Technologies such as these heat-storing materials bonding capable of using, sintering, plastic packaging, lamination are processed the solid structure of arbitrary shape.Because calcium chloride is to be filled in the cavity of foam metal particle, so zeolite and foam metal not only account for weight but also account for volume in filling heat-storing material, calcium chloride only accounts for weight and does not account for volume in the filling heat-storing material.The volume adding proportion of zeolite and foam metal can adopt following scheme: 1. the volume adding proportion of zeolite is 30%, and the volume adding proportion of foam metal is 70%; 2. the volume adding proportion of zeolite is 60%, and the volume adding proportion of foam metal is 40%, and 3. the volume adding proportion of zeolite is 90%, and the volume adding proportion of foam metal is 10%.Above-mentioned three kinds of materials have the abundant relatively characteristics of commodity resource, and the unit volume financial cost is low.
General biogas is under the condition of room temperature normal pressure, and every cubic metre of Lowlevel thermal energy that has is 15～25MJ, and promptly its energy storage density is 15～25MJ/m under condition of normal pressure
3And can reaching every square metre, the related energy storage equipment 4 theoretical energy storage densities of the utility model reach 800MJ/m
3More than, be existing more than tens times of biogas facility that store.
