Domestic sewage gas purification and pressure stabilization equipment

Abstract

The invention provides a domestic biogas purification processing method and apparatus, wherein the apparatus comprises a gas control valve, a moisture trap, a devulcanizer, a pressure stabilizator and a pressure testing meter all mounted in a mounting box and in connection through interconnecting gas tubes. The moisture trap is provided with a bottom drainage control valve. The apparatus integrates the functions of methane dehydration, desulfurizing and pressure stabilizing.

Description

technical field [0001] The invention relates to a technology for purifying and treating civil biogas, in particular to a device for purifying and stabilizing civil biogas. Background technique [0002] At present, the use of biogas energy is widely promoted in rural areas to replace burning wood, straw and coal, use clean, non-polluting energy, and improve the living environment in rural areas. When farmers use biogas energy, it is not conducive to direct use because the biogas contains toxic sulfide gas and moisture. Chinese patent application number: 02204809.X discloses the technology of "rural household biogas accessories integrator". It does not disclose the specific structure of each component, but only briefly describes the comprehensive framework of the process flow, only from the disclosed instructions and drawings. As far as the desulfurizer is concerned, the feed port and the discharge port of the desulfurizer are one port, and its structure is unreasonable. If ...

When farmers use biogas energy, because the biogas contains toxic sulfide gas and moisture, it is not conducive to direct use

Chinese patent application number: 02204809.X discloses the technology of "rural household biogas accessories integrator". It does not disclose the specific structure of each component, but only briefly describes the comprehensive framework of the process flow, only from the disclosed instructions and drawings. As far as the desulfurizer is concerned, the inlet and outlet of the desulfurizer are the same, and its structure is unreasonable

If you want to replace the desulfurizer during use, you must disassemble the connecting pipe, take it out and replace it, and then install it again after changing the material, which is very inconvenient to use

Its pressure measuring device uses a floating display method, the displayed numbers are not easy to see clearly, and the transparent tube is easily damaged, which is inconvenient to use

The dehydrator does not have a drain valve to discharge the accumulated water, and the user must disassemble the dehydrator before pouring out the accumulated water, which is even more inconvenient to use

The integrator only uses a gas control valve, which has a poor effect on stabilizing the pressure of the biogas used. When the user burns the biogas, the flame is unstable. When the biogas pressure is high, the combustion will be wasteful and the combustion effect will be poor.
