Embodiment 1

[0021] Example 1, in figure 1 Among them, the biogas device in the industrial heating furnace according to the present invention includes a biogas digester 4, a heating chamber 3 located outside the biogas digester, the upper part of the biogas digester is biogas 5, and the lower part is fermentation material 20. Between the biogas digester and the bucket 2 Connected with a drain pipe 23, an outer bucket 1 is arranged on the outside of the bucket, the outer bucket is higher than the bucket, a drain valve 24 is installed on the outer bucket, a pressure gauge 6 is set on the top of the biogas tank, and a Cleaning valve 21, the cleaning valve is used for cleaning and clearing the biogas digester, the heating chamber is an annular cavity surrounding the sides and bottom of the biogas digester, and an insulation layer 18 is preferably arranged on the outside of the heating chamber, and the bottom of the biogas digester is preferably A mixer 22 is provided, a delivery pipe 9 is conn...

Embodiment 2

[0023] Embodiment 2, biogas is used for firing ceramic building materials (such as magnetic plates, tiles, etc.) 3 , under the heating condition of 55-60 ℃, the daily biogas production can be at least 3000m3 3 , build a capacity of 1500m 3 The gas storage, the volume of the prismatic kiln is 36m 3 , based on the maximum annual output of ceramic products of 10,000 tons, and the daily output of ceramic products per furnace is 40 tons. The actual working days of the rib-type kiln are 250 days a year, and the amount of biogas required per cubic meter per day for each shuttle kiln is 75m 3 Calculated, the maximum amount of biogas consumed per day is 36×75=2700m 3 , the annual gas consumption is 250×2700=675,000 cubic meters, the maximum daily consumption of biogas is less than the minimum daily production of biogas, therefore, the biogas tank capacity is 2000m 3 , under the heating condition of 55-60 ℃, the biogas production capacity can fully meet the volume of 36m 3 , with an...

Embodiment 3

[0024] Embodiment 3, the application method and application device of the biogas in the industrial heating furnace according to the present invention can also be used for boiler heating.

Abstract

The invention discloses a method and device for applying methane to an industrial hating furnace. The device comprises a methane tank (4) and a heating chamber (3), wherein the methane tank is communicated with a bucket (2); the methane tank is connected with a methane storeroom (16) through a delivery pipe (9); the methane storeroom is connected with a flame gun (12) positioned in the industrial heating furnace through an output pipe (15); the output pipe is connected with an air compression pipe (13); and the heating chamber is connected with a hot air discharging pipe (25) in the industrial heating furnace through a hot air pipe (10). By utilizing the device, a fermentation material is filled in the methane tank firstly, the methane tank is heated to 50-80 DEG C so that the fermentation material is fermented and decomposed at high temperature to generate methane, then the methane is stored and delivered to the industrial heating furnace so as to be ignited, and then compressed air is introduced to the methane so that the methane sufficiently combusts in the industrial heating furnace after being mixed with the compressed air. By utilizing the method and device provided by the invention, the quality of the combusted product can be ensured, the gas cost can be greatly reduced, energy sources are saved, waste materials are sufficiently utilized, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a biogas application method, in particular to a biogas application method and application device in a heating furnace. Background technique [0002] Biogas is a flammable mixed gas whose main component is methane (CH 4 ) and carbon dioxide (CO 2 ), of which methane is 60-70%. Biogas is mainly produced by fermenting and decomposing waste materials such as urban garbage, human and animal manure, and plant straw. It is a renewable energy source with a calorific value and purity much higher than that of coal gas, similar to natural gas, but low in price. Due to biogas fermentation materials— Abolition of old material sources is highly dispersed, the construction of existing biogas digesters is relatively scattered, and the gas production of biogas is low. It is mainly suitable for use in rural households with small gas consumption. With the rapid development of my country's industry, most of the enterprises with industrial heati...
