What supporting equipment should be used for the construction of pig farm biogas digesters
With the continuous development of the breeding industry, the disposal of pig farm waste has become an important issue. As an effective waste treatment method, biogas digesters have been widely used in pig farms. However, in order for the digester to function properly and to perform its maximum function, it needs to be equipped with some necessary supporting equipment. This article will introduce the supporting equipment that should be equipped when building a biogas digester in a pig farm.
1. Feeding device.
The feeding unit is an important part of the digester, and its main function is to transport the waste generated from the farm to the digester. The feeding device is generally composed of a feed pipe, a pump and a conveyor belt. When selecting a feed unit, the capacity of the digester and the type of waste need to be considered to ensure that the feed unit can meet the actual demand.
2. Stirring device.
The main function of the stirring device is to fully mix the materials in the biogas digester and promote the growth and fermentation of microorganisms. The stirring device is generally composed of a stirrer, a stirring shaft and a reducer. When selecting a mixing unit, the capacity of the digester and the characteristics of the material need to be considered to ensure that the mixing unit can meet the actual demand.
3. Discharging device.
The main function of the discharge unit is to discharge the fermented biogas slurry out of the digester. The discharging device is generally composed of a discharge pipe, a discharge pump and a conveyor belt. When selecting a discharge device, it is necessary to consider the capacity of the digester and the discharge method to ensure that the discharge device can meet the actual demand.
Fourth, the gas collection system.
The main function of the gas collection system is to collect the biogas produced in the digester. The gas collection system generally consists of a gas collection pipe, a gas transmission pipe and a gas separator. When selecting a gas collection system, the capacity of the digester and the production of biogas need to be considered to ensure that the gas collection system can meet the actual demand.
5. Sewage treatment system.
The main function of the sewage treatment system is to treat the wastewater produced after the fermentation of the biogas digester. The sewage treatment system generally consists of sedimentation tanks, filters, disinfection tanks and drainage pipes. When choosing a sewage treatment system, it is necessary to consider the type of wastewater and discharge standards to ensure that the sewage treatment system can meet the actual needs.
6. Monitoring system.
The main function of the monitoring system is to monitor various indicators in the digester, such as temperature, pH value, methane content, etc., to ensure the normal operation of the digester. The monitoring system is generally composed of sensors, data collectors and monitoring software. When selecting a monitoring system, it is necessary to consider the type and accuracy requirements of the monitoring items to ensure that the monitoring system can meet the actual needs.
7. Safety protection devices.
The main function of the safety guard is to ensure the safe operation of the biogas digester and prevent accidents. The safety protection device is generally composed of explosion-proof valves, safety valves, pressure gauges and alarms. When selecting safety guards, it is necessary to consider the safety risks and protection requirements of the biogas digester to ensure that the safety guards can meet the actual needs.
In short, the construction of pig farm biogas digester needs to be equipped with the necessary supporting equipment to ensure the normal operation and maximum function of the biogas digester. When choosing supporting equipment, it is necessary to consider the actual situation and needs, and choose equipment with reliable quality and stable performance. At the same time, it is also necessary to pay attention to the maintenance and maintenance of the equipment to ensure the long-term stable operation of the equipment.
