[0002] In the existing oil and gas recovery device, the brine can condense oil and gas, and can also be used as a defrosting agent to defrost the oil and gas condenser. The refrigerant and the defrosting agent are the same medium, but its density will vary with the temperature. As the number of mode switching increases, the refrigerant in the liquid storage tank of the refrigeration mechanism will continue to decrease, and the defrosting mechanism will The increasing amount of defrosting agent in the defrosting liquid tank leads to an unbalanced liquid volume in the oil and gas recovery device. If the amount of defrosting agent in the defrosting liquid tank is too much, it will affect the cooling type oil and gas recovery device. work effect

Embodiment Construction
[0026] The present invention provides an oil gas recovery device and a control method. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0027] In the description of the present invention, it should be understood that the terms "installation", "connection", etc. should be understood in a broad sense, and those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations .
[0028]During the oil and gas recovery process, the second oil and gas condenser 12 further lowers the temperature of the oil and gas output from the first oil and gas condenser 11, and the temperature of the oil and gas output by the second oil and gas condenser 12 is relatively low, which means that the second oil and gas condenser 12 The problem of...

The invention discloses an oil gas recovery device and a control method. The oil gas recovery device comprises a control device, a first oil gas condenser, a second oil gas condenser, a first refrigeration mechanism, a second refrigeration mechanism, a defrosting mechanism and a tail gas heater. The first oil gas condenser, the second oil gas condenser and the tail gas heater are sequentially arranged in the oil gas inlet and outlet direction. The first refrigeration mechanism cools a refrigerant returned by the first oil gas condenser, the second refrigeration mechanism cools a refrigerant returned by the second oil gas condenser, and the defrosting mechanism provides a defrosting agent for the second oil gas condenser and comprises a defrosting liquid tank. The defrosting liquid tank is connected with the upper part of a second liquid storage tank through a balance pipe; according to the oil gas recovery device, when the liquid level in the defrosting liquid tank is too high, the defrosting agent in the defrosting liquid tank can spontaneously enter the second liquid storage tank, so that the liquid amount between the second liquid storage tank and the defrosting liquid tank is kept relatively stable.
Description
technical field [0001] The oil gas recovery treatment of the present invention relates to the technical field, in particular to an oil gas recovery device and a control method. Background technique [0002] In the existing oil and gas recovery device, the brine can condense oil and gas, and can also be used as a defrosting agent to defrost the oil and gas condenser. The refrigerant and the defrosting agent are the same medium, but its density will vary with the temperature. As the number of mode switching increases, the refrigerant in the liquid storage tank of the refrigeration mechanism will continue to decrease, and the defrosting mechanism will The increasing amount of defrosting agent in the defrosting liquid tank leads to an unbalanced liquid volume in the oil and gas recovery device. If the amount of defrosting agent in the defrosting liquid tank is too much, it will affect the cooling type oil and gas recovery device. work effect. [0003] It can be seen that the p...
