Dry and wet dual-purpose stem pressing glass reinforced plastics biomass pool, producing method and facility thereof

Abstract

The invention relates to a wet and dry dual-purpose mould pressing fiber-glass reinforced plastics methane tank as well as the production method and the facility thereof, and is characterized in that dry ferment and wet ferment performed in a same fermentation tank is realized, air production can be improved by the dry ferment in winter, the discharging and the feeding are performed conveniently by the wet ferment in summer, the production method adopts positive or vibration, vacuum and pressure continuous mould pressing methods, and the production facility adopts a compacting tool set and a vibration-type vacuum hydraulic machine. Compared with the prior art, the production facility of the invention reduces 90 percents of investment cost, reduces 85 percents of energy consumption, reduces 5 percents of product cost on the precondition of same capacity; in addition, on the basis, the flexural modulus are improved by 1.5 times and 2 times respectively compared with the flexural modulus of the prior mould pressing fiber-glass reinforced plastics and the hand lay-up fiber-glass reinforced plastics; therefore, the safety factor is increased, the safety operation of the methane tank is ensured, the service life is prolonged, so as to facilitate the commercialization of the fiber-glass reinforced plastics methane tank and the technology improvement of the mould pressing fiber-glass reinforced plastics industry, and be suitable for the popularization in China.

Description

Technical field [0001] The invention belongs to the technical field of biogas digesters, in particular to a molded glass fiber reinforced plastic biogas digester capable of realizing dry and wet two fermentation methods, a production method and facilities thereof. Background technique [0002] In the existing household biogas digester technology, there are mainly two types of fermentation methods: dry fermentation and wet fermentation. Dry fermentation has less water content and higher fermentation heat production, which is conducive to gas production in winter and can reduce the volume of the tank. One-time charging is required and it is difficult to load and discharge materials, and a fully-sealed biogas digester with a large opening is required. Wet fermentation is the opposite of dry fermentation. It has high water content and low fermentation heat production, which is not conducive to gas production in winter. easy. In the above-mentioned prior art, the biogas digeste...

Problems solved by technology

Indeed, Sichuan Hongqi Company has achieved a breakthrough in the industry, and it is a breakthrough in the industry in the world, but its still existing disadvantage is that the equipment investment is too large: the depreciation fee, overhaul fee, and electricity fee of its equipment of more than 10 million yuan will cost each biogas The cost of the biogas digester has increased by 100 yuan. Such a huge investment, high cost and high energy consumption have exceeded the cost of the biogas digester and the affordability of the rural market in our country.
