Where is rotary vane vacuum pump used in slaughterhouse
In many slaughterhouses (such as cattle and pigs), rotary vane vacuum pumps are used to remove debris and remove fat and other useless parts. In this process, the rotary vane vacuum pump operates continuously at low vacuum like a vacuum cleaner to recycle fat, debris or target products into the container. Sometimes using vacuum and steam at the same time can reduce the amount of bacteria (steam can kill bacteria in large quantities). The bone marrow removal system also uses vacuum. After the BSE crisis, slaughterhouses have adopted a new measure, that is, bone marrow needs to be removed before animals are divided to prevent and eliminate BSE in livestock over 1 year old. The manufacturer of rotary vane vacuum pump intends to introduce where rotary vane vacuum pump is used in slaughterhouse.
The main source of slaughterhouse wastewater is a series of wastewater discharged from slaughtering process. The main characteristics of wastewater are: high concentration of suspended solids and high concentration of organic pollutants. During slaughtering, a certain amount of blood, hair and bone fragments were discharged. Feces, intestines and fat. The wastewater is directly discharged, which affects the health of the surrounding residents.
Vacuum technology product series:
Single stage rotary vane vacuum pump, double stage rotary vane vacuum pump, oil-free piston vacuum pump, micro compressor, roots vacuum pump, vacuum unit and vacuum system, vacuum pump oil, vacuum pump accessories, etc
In slaughterhouses, rotary vane pumps are used to remove bone marrow, debris, poultry viscera and remove special dangerous substances.
Selection of sludge treatment process scheme
1) Analysis of sludge characteristics
The sludge produced in the process of sewage treatment is mainly sludge from sedimentation tank and scum from air flotation tank.
2) Comparison of sludge treatment processes
Sludge is the product of sewage treatment process and an important part of the whole sewage treatment station. The purpose of treatment is to reduce the moisture content and volume of sludge, achieve stable performance and create conditions for further disposal.
3) Selection of integrated sludge treatment process
The general process of sludge treatment is: thickening → digestion → dehydration → drying → treatment.
Considering that if digestion treatment is adopted, a series of structures and equipment such as digester, heating system, mixing and biogas treatment need to be added, so the investment is increased and the economic benefit is poor. Therefore, sludge digestion is not considered in this design.
