Problems solved by technology

Those in the field are well aware that biogas mainly contains methane, hydrogen sulfide and carbon dioxide gas. Hydrogen sulfide gas is a highly corrosive gas that is also harmful to human health. Therefore, desulfurization processes are used in biogas systems. However, desulfurization cannot achieve a 100% effect. In addition to long-term use, the desulfurization effect will gradually decrease, so some hydrogen sulfide gas will be transported to the ignition valve with methane. The traditional ignition valve for biogas uses a copper outlet pipe. Because the inner diameter of the air outlet pipe is only about 2mm, after long-term use, due to chemical reactions, it is easy to cause the air outlet pipe to be blocked, affecting the normal use of users, and even bringing safety hazards

Abstract

The invention discloses an ignition valve for methane, which comprises a valve body. A gas supply channel and a valve element are arranged in the valve body. An ignition device and an ignition switch for controlling the valve element and the ignition device are arranged on the valve body. An ignition pin is connected to the ignition switch. A gas outlet pipe in fit with the ignition pin is also arranged on the valve body. The ignition valve is characterized in that: the gas outlet pipe at least comprises a section of ceramic pipe, and the methane at an ignition opening is exhausted by the ceramic pipe. The technical scheme of leading the methane out by a ceramic pipe is adopted, and a ceramic material is anticorrosive and may not be reacted with a hydrogen sulfide gas to avoid the condition of blockage of a gas outlet, so the ignition valve has the advantages of long service life, high safety, simple structure and low production cost.

Description

【Technical field】 [0001] The invention relates to the field of ignition devices for biogas, in particular to an ignition valve for biogas. 【Background technique】 [0002] The gas safety valve is mainly used in gas kitchen utensils, and plays the role of connecting gas and ignition. Commonly used gas includes coal gas and natural gas. As the country attaches great importance to energy conservation and environmental protection, a new type of environmentally friendly gas has been vigorously promoted. This gas is biogas, which is mainly used in the vast rural market. For the construction of biogas projects, the Ministry of Agriculture has given strong support. Those in the field are well aware that biogas mainly contains methane, hydrogen sulfide and carbon dioxide gas. Hydrogen sulfide gas is a highly corrosive gas that is also harmful to human health. Therefore, desulfurization processes are used in biogas systems. However, desulfurization cannot achieve a 100% effect. In ad...
