[0002] In the natural gas dehydration treatment industry, the conventional dehydration treatment equipment all adopts the circulating supercharger to carry out the circulating superpressure, and the regenerative gas continuously circulates and flows to regenerate the molecular sieve in the regenerative tower, the circulating compressor needs to be stopped regularly to overhaul and replace the piston ring and the sealing packing etc. UTILITY MODEL CONTENTS
[0003] In view of the deficiencies in the prior art, the utility model provides a pressure regulating regenerative dehydration system without circulating supercharger, which is simple in structure, can complete the dehydration regeneration of natural gas without using the compressor, and is low in maintenance cost.
[0004] To achieve the above object, the utility model adopts the following technical scheme: a pressure regulating regenerative dehydration system without circulating supercharger, comprising an air inlet, the air inlet is connected with a main pipeline, a regenerative pipeline is connected on the main pipeline, the main pipeline is also connected with an adsorption tower, a regenerative tower is connected on the regenerative pipeline, the regenerative pipeline is connected at the front end of the adsorption tower of the main pipeline, the end of the main pipeline is connected with an exhaust port, a flow regulating device is connected on the main pipeline, and a flow detection device is connected on the regenerative pipeline.
[0005] Further, the flow regulating device is a regulating valve.
[0006] Further, the regulating valve is connected on the main pipeline, and the starting end of the regenerative pipeline is located at the front end of the regulating valve.
[0007] Further, the flow detection device is an electronic flowmeter.
[0008] Further, the regulating valve adopts an electric valve or a pneumatic valve and is connected with the electronic flowmeter signal.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] 1、 the utility model can produce the pressure difference through the regulating valve, so that the valve after the main pipeline pipeline pressure is lower than the pressure of the regenerative pipeline, meets the differential pressure of regenerative circulation flow, reaches the function of the conventional circulating compressor, cancels the circulating compressor, eliminates the noise influence generated by the compressor motor, can also save the electric energy, reduces the operation cost simultaneously;
[0011] 2. By using an electric or pneumatic valve for the regulating valve, and in conjunction with a flow meter, the flow rate of the regeneration pipeline can be automatically detected, thereby automatically adjusting the opening of the regulating valve and controlling the pressure after the regulating valve, so that the regeneration gas can return to the main pipeline, making the dehydration system more intelligent.

[0013] In the diagram: 1. Air inlet; 2. Regulating valve; 3. Flow meter; 4. Controller; 5. Adsorption tower; 6. Main pipeline; 7. Regeneration pipeline; 8. Regeneration tower; 9. Exhaust port; Detailed Implementation
[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0015] like Figure 1 The illustrated pressure-regulating regeneration dehydration system without a circulating booster includes an air inlet 1 connected to a main pipeline 6. A regeneration pipeline 7 is connected to the main pipeline 6, which is also connected to an adsorption tower 5. A regeneration tower 8 is connected to the regeneration pipeline 7. The end of the regeneration pipeline 7 is connected to the end of the main pipeline 6, and the end of the main pipeline 6 is connected to an exhaust port 9. A flow regulating device is connected to the main pipeline 6, and a flow detection device is connected to the regeneration pipeline 7.
[0016] The process of using this invention is as follows: Natural gas requiring dehydration enters through inlet 1. A portion passes through main pipeline 6 to adsorption tower 5 for adsorption, while the other portion passes through regeneration pipeline 7 to regeneration tower 8, where the adsorbent in the regeneration tower is dehydrated. Subsequently, the natural gas in the regeneration pipeline passes through the regeneration gas separation component of the regeneration tower for further dehydration, and finally converges at regulating valve 2 on main pipeline 6. During the above process, a flow detection device continuously monitors the flow rate of regeneration pipeline 7. When a decrease in flow rate is detected, a flow regulation device is activated to allow more natural gas to flow into regeneration pipeline 7. The flow regulation device maintains the pressure in the regeneration pipeline higher than the pressure after regulating valve 2 on main pipeline 6, ensuring that the regeneration gas in regeneration pipeline 7 continuously flows back to main pipeline 6. In this invention, adsorption tower 5 and regeneration tower 8 are interconvertible. When adsorption tower 5 completes adsorption and the adsorbent reaches saturation, the adsorption tower 5 can be converted into a regeneration tower, and the regeneration tower 8 into an adsorption tower, by reconnecting the pipeline or controlling the valve, thus repeating the above process.
[0017] Further, the flow regulating device is a regulating valve 2. Specifically, the flow regulating device of the utility model is a regulating valve 2, specifically, electric or pneumatic valve is adopted, when the flow detecting device detects that the flow of the regenerating pipeline 7 reduces to a certain value, it indicates that the pressure of the regenerating pipeline approaches the pressure of the main pipeline, the flow of the regenerating gas is insufficient, the flow detecting device can adopt the flowmeter 3, then the signal is transmitted to the PLC controller 4, the PLC controller 4 controls the opening of the regulating valve 2, so that the regenerating gas can continuously circulate.
[0018] Finally, it is explained that the above examples are only used to illustrate the technical solutions of the utility model and are not limited. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the utility model, which should be covered in the scope of the claims of the utility model.
