Natural gas direct oxygen enrichment blending and mixing valve device

The utility model discloses a natural gas direct oxygen-enriched blending and mixing valve device which is characterized by comprising an air compressor (5), a dryer (6) and an oxygen-enriched membrane skid-mounted device (7) which are sequentially connected through a compressed air pipe (102), and a natural gas check valve (2) and a natural gas pressure regulating valve (3) which are sequentially connected through a natural gas conveying pipe (101). According to the device, the natural gas and the oxygen-enriched gas can be rapidly and fully mixed, and the combustion-supporting combustion effect after the natural gas and the oxygen-enriched gas are mixed is further improved. 本实用新型公开了一种天然气直接富氧掺混及混合阀装置，其特征在于，包括通过压缩空气管(102)依次连接的空气压缩机(5)、干燥机(6)和富氧膜撬装装置(7)，以及通过天然气输气管(101)依次连接的天然气止逆阀(2)和天然气压力调节阀(3)。该装置能够实现天然气与富氧气体快速充分掺混，进一步提高天然气与富氧气体掺混后的助燃燃烧效果。
