Description

Methane incinerator

Technical Field

The utility model belongs to the technical field of sewage treatment, and particularly relates to a methane incineration device.

Background

In existing sewage treatment, anaerobic tower sludge produces a large amount of biogas. The traditional biogas treatment mode is that biogas flows to a biogas pipeline through a water seal, is stored by a biogas floating roof tank and then flows to an incinerator for incineration. In the incineration process, the methane yield is also changed to a certain extent due to the change of the temperature of the anaerobic tower and the COD of the inflow water, and the condition that the methane incinerator is easy to extinguish or burns incompletely is caused by the instability of the air inflow.

Detailed Description

The following describes the detailed implementation of the embodiments of the present utility model with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other.

The utility model will be described in detail below with reference to the drawings in connection with exemplary embodiments.

Referring to fig. 1, the biogas incineration device of the utility model comprises four

anaerobic towers

1, 2, 3 and 4, a floating roof tank 5, a fan 7, a gas storage tank 8 and a biogas generator 9, wherein the upper ends of the four anaerobic towers are provided with waste gas outlets, each waste gas outlet is respectively communicated with the input end of the floating roof tank 5, the output end of the floating roof tank 5 is provided with a water seal device 6 for preventing biogas backflow and tempering, the output end of the water seal device 6 is connected with the input end of the fan 7, the output end of the fan 7 is communicated with the input end of the gas storage tank 8, and the output end of the gas storage tank 8 is connected with the input end of the biogas generator 9; the biogas generator 9 is provided with a water inlet for providing desalted water for the biogas generator, the water inlet is connected with the output end of the pure water barrel 10, the input end of the pure water barrel 10 is provided with a water inlet electromagnetic valve 11, and desalted water is heated by biogas combustion and is converted into steam which enters a steam pipeline 12 from the water inlet.

The utility model discloses in, marsh gas is by polyester waste water entering

anaerobic tower

1, 2, 3, 4 after acidizing the pond acidizing reaction and carries out the waste gas that biochemical treatment produced, gathers to floating roof tank 5 through the pipeline is concentrated and stores. The outlet of the floating roof tank is provided with a water seal device 6 for preventing the biogas from flowing back and tempering. And then the biogas is stably conveyed to the gas storage tank 8 for storage through the fan 7, so that the biogas with a certain storage capacity in operation of the biogas machine 9 is ensured to be supplied to the biogas machine for combustion. The desalted water is controlled by a water inlet electromagnetic valve 11 to enter a pure water barrel 10, is stored and supplied to a methane machine 9, and is heated by methane combustion to be converted into steam to enter a steam pipeline 12.

The utility model mainly uses the fan 7 to increase the conveying pressure, so that the biogas is stably conveyed to the gas storage tank 8 at a constant speed for temporary storage, and the biogas storage can also be buffered. The small impurities in the filtered biogas enter the filter through the pipeline to prevent the impurities from entering the distributor to cause blockage, and then enter the biogas machine. The fire power of the biogas machine in combustion is controlled by the pressure in the biogas pipeline: when the gas production pressure of the anaerobic tower reaches 2.5 kilopascals, the first fire grate is automatically started to burn, when the gas production of the anaerobic tower is increased, the pressure is continuously increased to 3.5 kilopascals, the first fire grate is started to burn simultaneously, and when the pressure is less than 1 kilopascal, the machine is automatically extinguished and the pressure reaches the burning condition, the automatic ignition and burning are performed. The pressure data is transmitted to the equipment by the electronic pressure sensor, and the running state is automatically switched by the equipment, so that the requirements of automatically burning methane and automatically adjusting the fire power are met, and 0.25 ton of water vapor is generated per hour through burning.

When the biogas storage device is used, when the biogas in the anaerobic tower is discharged, the biogas enters the water seal device through the floating roof tank, then enters the gas storage tank through the pipeline under the pressurization of the fan, the water inlet electromagnetic valve of the biogas machine is opened after the rated pressure is reached, the biogas machine starts to work, the biogas starts to burn through the biogas machine, and water vapor is generated and enters the steam pipeline.
