Description

Back pressure type automatic water discharge float valve of methane condenser

Technical Field

The utility model relates to a marsh gas condenser ball-cock assembly technical field specifically is a marsh gas condenser ball-cock assembly float valve that drains automatically of back pressure type.

Background

At present, China has become a world with large energy production and consumption, but the energy consumption level per person is low. With the continuous development of economy and society, the energy demand of China will continuously increase. Aiming at the current energy shortage situation, all countries in the world take profound thinking, strive to improve the energy utilization efficiency, promote the development and application of renewable energy, reduce the dependence on imported petroleum and strengthen the energy safety.

The methane industry, which is one of the important development directions of renewable energy, is rapidly developed in recent years, and the proportion of the methane industry is getting larger and larger. Over a quarter of a year the country invests 211 billion for biogas projects. By 2017, nearly 5500 thousands of methane users exist in China, and the methane contains much water and hydrogen sulfide and needs to be dehydrated and desulfurized before use. During the transportation in the biogas station, a water condenser is required to be added at intervals. The water condenser is used for discharging condensed water in the conveying process.

At present, drainage of a condenser has two options: 1. water was manually drained at intervals. 2. The lower end of the water condenser is additionally provided with a water seal, and water is automatically drained under the pressure of the water. However, at present, two water discharging modes, namely a water sealing mode is difficult to create back pressure for the fermentor. The manual water discharge is easy to cause problems such as air leakage or excessive water storage due to human reasons. Therefore, a back pressure type automatic water discharging methane condenser ball cock is provided.

Preferably, the lower part of the left side of the water condenser is provided with an air inlet flange, the top of the water condenser is provided with an air outlet flange, and the middle part of the right side of the water condenser is provided with a main air outlet flange.

Preferably, the lower end of the valve rod penetrates through the valve cover and extends into the valve seat, and the upper end of the spring is clamped at the bottom of the valve cover.

Preferably, the gasket positioned at the bottom of the inner cavity of the water condenser is further arranged on the outer side of the bottom of the valve seat.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, convenient and practical controls the floater through the water level and pulls up the valve rod and drains, and the water level reduces, pushes down the valve rod with the spring again and reaches sealed effect. The device is convenient, reliable and unpowered, can achieve unattended operation, and has the advantages of practical function, low cost, strong automation, no energy consumption and reliable performance.
