Monitoring and early-warning platform based on biogas system energy utilizing efficiency method

Abstract

The invention relates to a monitoring and early-warning platform based on a biogas system energy utilizing efficiency method. The monitoring and early-warning platform comprises a body, a biogas slurry detecting unit, a biogas slurry storing unit, a biogas slurry collecting unit, a lifting unit and a warning unit, wherein the biogas slurry storing unit moves up and down relatively to the body; a water inlet valve and a water outlet valve of the biogas slurry storing unit are respectively arranged on a water inlet and a water outlet; a cushioning cavity is arranged at the water inlet valve; an impeller unit is arranged in the cushioning cavity and comprises a variable-pitch helical impeller assembly, a positioning bearing and a rotating shaft; for the blade shape of the nth (n is larger than or equal to 1 and less than or equal to N) variable-pitch helical impeller of the variable-pitch helical impeller assembly, the equations of a locus from one end near the water inlet valve to the other end of the variable-pitch helical impeller are Xi=r*cos (thetai+2PI*n / N), Yi=r*sin (thetai+2PI*n / N), Zi=(n-1)*(L+a) / N+(thetai / 2PI) m*(L-(N-1)a) / N; the biogas slurry collecting unit is used for conveying the biogas slurry in the cushioning cavity; and the lifting unit is used for enabling the biogas slurry storing unit to move up and down.

Description

technical field [0001] The invention relates to a biogas pit detection system, in particular to a biogas liquid component detection platform capable of performing deep water sampling and on-site analysis and detection functions in the biogas pit. Background technique [0002] Water is the source of life. With the rapid development of society and economy, the demand and dependence on water resources in the development of human society continue to increase, which puts severe pressure on the security of water resources. Based on the urgent needs of human development for water resources, it is necessary to detect biogas slurry components in water areas that need to be tested, select representative indicators, and build a water resource safety evaluation index system according to the connotation of water resource security. Quantitative and dynamic research on the overall situation can reflect the basic situation of the water resources system as a whole. [0003] The existing bio...

Problems solved by technology

[0003] The existing biogas slurry composition detection system uses more complex equipment, which will occupy a large area when used, and is not flexible enough; the sampling depth is also limited

[0004] Chinese invention CN201020551665.9 discloses a large and medium-sized biogas engineering device and its on-line monitoring and control system. The entire system is large in size, and the components used are scattered in multiple positions of the biogas digester; Stirring, the workload is very large, and it is not necessary to stir a large area just because of the detection; and the detection can only be performed at a fixed position
