Solar vacuum constant temperature biogas reactor

Abstract

The invention discloses a solar vacuum constant-temperature marsh gas reaction tank, comprising a base and a tank body, wherein the tank body is arranged on the base; the top of the tank body is provided with a gas outlet; the bottom of the tank body is provided with a slag discharge port and an inspection manhole; the tank body comprises an inner tank body and an outer tank body; two layers of supporting columns are arranged in an interlayer of the tank body; a hot coil is coiled on inner supporting columns and outer supporting columns arranged at the circumference respectively; the hot coil surrounding the inner supporting columns is coiled anticlockwise, and the hot coil surrounding the outer supporting columns is coiled clockwise; the hot coils are connected with an external marsh gas hot-water boiler respectively; and the bottom of the outer tank body is provided with a vacuum pump gas pipe connected with the interlayer of the tank body, the vacuum pump gas pipe is connected with an external vacuum pump, water is injected into the interlayer of the tank body, hot water is injected into the hot coils to improve the heat source utilization ratio by virtue of heat radiation formed by cross points so as to heat the reaction tank, then the water in the interlayer of the tank body is discharged, and gas is pumped out by using the vacuum pump to form a heat insulation layer, so that the uniformity degree of biogas slurry is improved, the temperature is kept constant, and the gas output is increased.

Description

Technical field [0001] The invention relates to the field of biogas generating equipment, in particular to a solar vacuum constant temperature biogas reactor. Background technique [0002] Existing biogas reactors are seriously affected by the external environment and climate, so the gas production will fluctuate greatly, especially in the case of low ambient temperature such as late autumn, cold winter and early spring, the sun has a short time and it is difficult to form a constant temperature state. In turn affect the effect of gas production. Summary of the invention [0003] The purpose of the present invention is to provide a solar vacuum constant temperature biogas reactor capable of uniformly mixing the biogas liquid in the tank, constant temperature and high gas production. [0004] The solar vacuum constant temperature biogas reactor of the present invention includes a base and a tank body. The base is supported by a high-strength nylon rod. A tank body is arranged on the...
