Semi-underground tunnel type methane autoclave

Abstract

The invention relates to a semi-underground tunnel type methane reaction still comprising a stock preparation pool, a gas production pool and a stock discharge pool. The gas production pool is arranged in the center of the reaction still, the stock preparation pool and the stock discharge pool are respectively arranged on the two sides of the gas production pool; a front and a rear protection fence are respectively arranged along the ground circumferences of the stock preparation pool and the stock discharge pool, a water renewing tank communicating with the stock preparation pool via a water renewing hole is arranged on the outer side of the stock preparation pool, a stock renewing bucket and a water supplying tube are arranged on the side of the stock preparation connecting with the ground, the outlets on the two sides of the gas production pool communicating with the stock preparation pool and the stock discharge pool are respectively a feed outlet and a discharge outlet; a feed device and a discharge device placed in the discharge tank are respectively arranged in the positions corresponding to the feed outlet and the discharge outlet; The gas production pool is equipped with a top cover plate on the top, the top cover plate is equipped with a methane outlet and a temperature detection hole, a temperature detector is arranged in the temperature detection hole; the gas production pool is equipped with a gas production operation device at the lower part of the pool, and a bottom tank plate at the pool bottom, the heat pipes are arranged in parallel under the bottom tank plate. The reaction still main body is assembled by sheets, so it is light, firm, durable, safe, highly effective, and convenient for installation.

Description

technical field [0001] The invention relates to a biogas reactor, in particular to a semi-underground tunnel type biogas reactor. Background technique [0002] Biogas is a kind of waste utilization, high-quality and low-cost high-quality fuel. At present, the development of my country's biogas industry is relatively slow. As far as the gas production device is concerned, its structure is simple and its technology is backward. Most of them use cumbersome methods to manually build simple biogas digesters, which can neither guarantee the quality and output of biogas, but also have various safety hazards such as water leakage and collapse. There are also tower-type biogas digesters built by pouring reinforced concrete, but they cost a lot, occupy a large area, and have poor implementation effects. There is a box-type biogas generating device. The main body of the device is a horizontal steel tank of about 50 cubic meters. The tank is divided into several compartments by partit...
