Description

Technical Field

[0001] The utility model relates to a skid-mounted condensed water recovery device, belonging to the technical field of wine production. Background Art

[0002] At present, condensate from winemaking production is recovered in the form of condensate collection tanks and independent pumps. The equipment is scattered, which is not conducive to on-site equipment layout.

[0003] like Figure 1 As shown in the figure, the traditional condensate recovery device consists of a condensate buffer tank and a condensate pump. Its operation method is: the condensate is collected in the condensate buffer tank through the pipeline, and the condensate pump automatically starts and stops according to the liquid level feedback on the condensate buffer tank. When the condensate in the condensate buffer tank increases and triggers the high liquid level, the condensate pump starts and pumps the condensate to the recovery point. The condensate buffer tank is equipped with a drain pipe to ensure that the tank is maintained at normal pressure. It can be seen from the above that this configuration requires a pump power supply. If it is set in a gas explosion area, an explosion-proof motor must be considered. At the same time, if a large amount of condensate is concentrated, cavitation is likely to occur.

[0004] Therefore, there is an urgent need in the art for a skid-mounted condensate recovery device that does not require power distribution and is not prone to cavitation. Summary of the invention

[0005] The utility model aims to solve the problem of danger in condensed water recovery in the prior art.

[0006] In order to achieve the purpose of solving the above-mentioned problems, the technical solution adopted by the utility model is to provide a skid-mounted condensate recovery device, including a condensate buffer tank, wherein two main pipelines are arranged on the condensate buffer tank, each main pipeline is divided into two branch pipelines, one group of branch pipelines is connected to a first stop valve and a second stop valve, one group of branch pipelines is connected to a first connecting valve and a second connecting valve, the two connecting valves are respectively connected to a first pneumatic steam trap pump and a second pneumatic steam trap pump, a third stop valve and a fourth stop valve are respectively arranged on the two pipelines connected to the pneumatic steam trap pumps, and the condensate reflux control is controlled by adjusting the condensate liquid level of the two pneumatic steam trap pumps themselves.

[0007] Preferably, the volume of the condensate buffer tank is determined according to its actual recovery volume.

[0008] Preferably, the installation height of the condensate buffer tank is not less than 1m.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. The utility model has a simple structure, simple operation, automatic adjustment, no need for power distribution, and reduces restrictions on use in explosive environments; no electrical control is required, and the condensate discharge is automatically controlled according to the liquid level, with a low failure rate and long service life.

[0014] In order to make the present invention more clearly understood, a preferred embodiment is described in detail with reference to the accompanying drawings as follows:

[0015] like Figure 2 As shown, the utility model provides a skid-mounted condensate recovery device, which includes a condensate buffer tank 1, a first pneumatic steam trap pump 6, and a second pneumatic steam trap pump 9.

[0016] The specific structure of the utility model is as follows: a condensate inlet pipe port is arranged on the top of the condensate buffer tank 1, and the pipeline below the condensate buffer tank 1 is connected to the first pneumatic steam trap pump 6 and the second pneumatic steam trap pump 9. A first stop valve 2 is arranged in front of the first pneumatic steam trap pump 6, and a second stop valve 3 is arranged in front of the second pneumatic steam trap pump 9. The connecting pipe above the first pneumatic steam trap pump 6 and the second pneumatic steam trap pump 9 is connected to the condensate buffer tank 1. A third stop valve 4 is arranged behind the first pneumatic steam trap pump 6, and a third stop valve 5 is arranged behind the second pneumatic steam trap pump 9. When the pneumatic steam trap pump is not working, the float is at a low liquid level, the air inlet valve is closed and the exhaust hole is opened to connect to the atmosphere. When the condensate flows into the pump from the condensate buffer tank 1, the float rises and triggers the mechanism to open the air inlet valve, and the air inlet pressure is higher than the static pressure of the condensate buffer tank 1, so the condensate is discharged. As the condensed water is discharged, the floating ball descends to trigger the mechanism to close the air inlet valve, so that the condensed water in the condensed water buffer tank 1 continues to enter the first pneumatic steam trap pump 6 and the second pneumatic steam trap pump 9. During the operation, the first connecting valve 7 and the second connecting valve 8 remain in a normally open state.

[0017] The above is only a preferred embodiment of the utility model, and is not any formal or substantial limitation of the utility model. It should be pointed out that ordinary technicians in this technical field can make some improvements and supplements without departing from the utility model, and these improvements and supplements should also be regarded as the protection scope of the utility model. Any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the spirit and scope of the utility model, which are all equivalent embodiments of the utility model; at the same time, any changes, modifications and evolutions of any equivalent changes made to the above embodiments based on the essential technology of the utility model are still within the scope of the technical solution of the utility model.
