solid-liquid separator

Biogas (BIOGAS) is produced after anaerobic decomposition and fermentation of organic waste. Organic waste includes animal manure, kitchen waste/commercial organic waste, agricultural waste, and municipal solid waste. The main components of biogas are methane (50%-80%) and carbon dioxide (20%-50%) and small amounts of other gases such as hydrogen, carbon monoxide, nitrogen, oxygen, and hydrogen sulfide. Among them, the calorific value of methane is as high as 9300Kcal/m3, which is suitable as an energy fuel.

 

Biogas power generation can effectively reduce global climate change emissions and create employment opportunities. It is estimated that by 2025, the compound annual growth rate of the biogas power generation market will exceed 4.5%, becoming an important global industry for sustainable development.

Sanmin Green Energy has a professional biogas power generation team, integrates the related equipment required for biogas power generation projects, and provides customers with one-time purchase of all equipment and related technologies and designs. It is your best partner for biogas power generation construction.

 

Sanmin provides biogas power generation related equipment:

1. Solid-liquid separation equipment

Before the anaerobic treatment of livestock manure and urine, the solid matter in the manure and urine needs to be removed to reduce the burden of wastewater treatment. The solid-liquid separation step involves coarse screening by trash racks, solid-liquid separators and other equipment to remove large solids, and then make the excrement and urine enter the primary sedimentation tank, and separate some insoluble solids through the principle of gravity.

A. Contamination equipment

B. Blender

C. Solid-liquid separator

2. Anaerobic treatment equipment

The main function of anaerobic treatment equipment is to maintain isolation from the atmosphere, provide an anaerobic environment for fecal and urine water to facilitate the growth of anaerobic microorganisms, carry out anaerobic fermentation, decompose the biogas produced by organic matter, store it in a gas storage facility, and use the biogas stock The sensor monitors the gas volume of the gas storage facility to achieve automatic control and design safety protection devices.

A. Anaerobic tank

B. Gas gathering and storage equipment

C. Biogas inventory sensor

3. Biogas transportation and purification

The biogas produced by anaerobic ferment passes through conveying equipment and biogas purification equipment to be used for power generation.

The biogas pump keeps the biogas supply pressure stable. Biogas purification equipment includes biogas desulfurization equipment and dewatering equipment. The purpose of desulfurization equipment is to reduce the concentration of hydrogen sulfide, avoid corrosion and crystallization from clogging the pipeline and cause equipment damage; and the dewatering device can reduce the moisture in the biogas and avoid flameout The situation occurs.

A. Biogas pump

B. Biogas desulfurization equipment

C. Auto drain

4. Aerobic treatment equipment

Pass air into the wastewater, increase the amount of dissolved oxygen in the water, and supply aerobic bacteria to decompose the remaining low-concentration organic matter. In the aeration treatment, the air is blown in by the blower, and the gas is released in the form of bubbles through the aeration plate and aeration tube, which increases the contact area of ​​air and water to increase the amount of dissolved oxygen. An aerator can also be used for water extraction and extraction process Generate low-pressure inhaled gas for aeration, or pump water to impact on the water surface to increase the contact between air and water and increase the amount of dissolved oxygen.

A. Blower

B. Aerator

C. Aeration tray

D. Aeration tube

5. Biogas power generation

A. Biogas generator

6. Biogas reuse

A. Biogas heating lamp

B. Biogas stove

C. Biogas boiler

D. Methane detector

7. Sludge treatment equipment

In order to avoid sludge siltation in the anaerobic tank, aeration tank and final sedimentation tank and enter a low effective capacity, the sludge needs to be removed regularly. Because the sludge has high water content and fine particles, the sludge can be dewatered for convenience

Processing such as storage, transportation and reuse.

A. Mud scraping equipment

B. Sludge dewatering equipment

C. Sludge collection equipment

8. Wastewater treatment

The sewage pump is used to transport sewage containing impurities in each stage, and the level gauge is used to monitor the body liquid level, and the sewage pump is turned on and off to automatically control the waste water system.

A. Dirt pump

B. Level gauge and level switch
