Construction method for novel round-pot-shaped high-efficiency combined methane tank

Abstract

The invention discloses a construction method for a novel round-pot-shaped high-efficiency combined methane tank, which relates to a construction method for a methane tank. The methane tank comprises an inlet pipe, a fermenting tank and a hydraulic discharging chamber, wherein the fermenting tank is arranged below the ground, the bottom of the fermenting tank is an inclined tile bottom, the hydraulic discharging chamber is arranged at the side surface of the lower bottom of the fermenting tank, the inlet pipe is obliquely arranged at one side of the higher bottom of the fermenting tank, the lower end of the inlet pipe is communicated with the lower part of the sidewall of the fermenting tank, the top of the fermenting tank is provided with a cut spherical shell-like tank arch which has an upward spherical surface, recessed parts at the periphery of the top of the cut spherical shell-like tank arch are provided with rammed earth, the central position of the cut spherical shell-like tank arch is equipped with a movable cover, a water storage loop is mounted on the movable cover, the center of the movable cover is provided with a gas conveying pipe communicated with the interior of the fermenting tank and the outside, a methane safety valve is mounted on the upper end of the gas conveying pipe, the top of the sidewall of the hydraulic discharging chamber is provided with an overflow port, and a hydraulic chamber cover plate is arranged on the top of the hydraulic discharging chamber. The construction method provided by the invention overcomes the problems of water leakage, gas leakage, insufficient gas storage space, a short service life, great potential safety hazards and a great occupied land area of conventional methane tanks.

Description

technical field [0001] The invention relates to a construction method of a biogas digester. Background technique [0002] The common advantages of GB / 4750-2002 "Standard Atlas of Household Biogas Dies", "04-B Small and High Efficiency Biogas Dies" trial operation plan, southern biogas production and comprehensive utilization technology, and training handouts for biogas production workers: 1. Convenient drainage Biogas residue and biogas slurry, 2. The cost of building a pond is low, 3. It can generate biogas after treating manure and straw. Disadvantages: 1. Leakage of water and air (leakage of the pool wall, uneven construction, no vibration and poor quality, poor sealing of the movable cover and pipe fittings and other factors lead to air leakage). 2. The gas storage space is insufficient, the pressure is low, and the amount of biogas available to farmers is too small (0.2-0.5m per day 3 Not enough for a family of 3-5 to need 1-1.5 m per day 3 The amount of biogas used;...
