Description

Technical Field

[0001] This utility model belongs to the technical field of natural gas compression equipment, and in particular relates to a dust removal structure for the intake of a natural gas compressor. Background Technology

[0002] A natural gas compressor is a mechanical device used to increase the pressure of natural gas. It achieves pressure increase by compressing the gas volume and is widely used in the extraction, gathering, transportation, storage, processing and application of natural gas. Its core function is to apply external force to natural gas through mechanical movement to increase its pressure in order to meet the transportation, storage or process requirements in different scenarios.

[0003] In natural gas compression systems, excessive dust content in the intake air can lead to accelerated wear of compressor components (such as pistons and valves), reduced equipment lifespan, and even malfunctions and shutdowns. Furthermore, some of the foam generated by spray dust suppression can hinder gas-liquid separation, and the tiny dust particles in the foam are difficult to settle, causing the dust content in the exhaust pipe to rebound. Therefore, it is necessary to provide a natural gas compressor intake dust removal structure that adopts a full-process treatment method of cyclone pre-separation, spray fine dust removal, and dynamic defoaming. This structure is suitable for high-dust gas sources, space-constrained scenarios, or scenarios with strict environmental protection requirements, ensuring the stable and efficient operation of the natural gas compression system.

[0021] In the following description, embodiments of the natural gas compressor intake dust removal structure of this utility model will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates a natural gas compressor intake dust removal structure according to an embodiment of the present invention, comprising a dust collector 1: a cyclone dust collector 2 is installed in the inner cavity of the dust collector 1; an intake pipe 5 is fixedly connected to the top left side of the dust collector 1; a drain pipe 7 is fixedly connected to the bottom of the dust collector 1; and an exhaust pipe 8 is fixedly connected to the top of the dust collector 1. The intake pipe 5, drain pipe 7, and exhaust pipe 8 are all connected to the inner cavity of the dust collector 1. A spray assembly 3 is provided below the cyclone dust collector 2. The spray assembly 3 includes support arms 31 fixedly connected to both sides of the inner cavity of the dust collector 1. A spray pipe 32 is fixedly connected to one end of each of the two support arms 31. A bend pipe 33 is fixedly connected to the bottom of the spray pipe 32. The right end of the bend pipe 33 extends to the outside of the dust collector 1 and is fixedly connected to a liquid supply pipe 34. The liquid supply pipe 34, the bend pipe 33, and the spray pipe 32 are connected. Through the combined use of the liquid supply pipe 34 and the bend pipe 33, the spray pipe... Water is supplied into the inner cavity of the dust collector 1, allowing the spray pipe 32 to spray water to reduce dust in the inner cavity of the dust collector 1. This increases the mass of the dust due to contact with water, accelerating the separation of dust from the air. A fine-mesh filter 4 is fixedly connected to the top of the inner wall of the dust collector 1. A defoaming component 6 is installed at the bottom of the inner cavity of the dust collector 1. The defoaming component 6 includes two defoaming discs 61 fixedly connected to the inner wall of the dust collector 1. The surface of the defoaming discs 61 has multiple rectangular holes. The surface of the mounting plate 62 has a liquid outlet groove 65. Through the cooperation of the defoaming discs 61 and the liquid outlet groove 65, the sewage foam is broken and decomposed into liquid by centrifugal force for sedimentation. The mounting plate 62 is fixedly connected between the two defoaming discs 61. An impeller 63 is rotatably connected to the inner cavity of the mounting plate 62. A waterproof motor 64 is fixedly installed on the top of the mounting plate 62. The output shaft of the waterproof motor 64 is fixedly connected to the impeller 63.

[0023] Working Principle: In use, the user introduces air through the air inlet pipe 5. After entering the inner cavity of the dust collector 1, the air is subjected to the centrifugal force of the rotating cyclone dust collector 2. Due to its larger mass, the dust particles diffuse outwards and separate from the air. Simultaneously, an upward airflow channel is formed within the rotating cyclone dust collector 2, allowing air to pass through the pores of the fine-mesh filter 4 and enter the inner cavity of the exhaust pipe 8. At the same time, the liquid supply pipe 34 is connected to a water source, causing the spray pipe 32 to spray water outwards. The water comes into contact with the dust, thus reducing its mass. As the dust collection system intensifies, the dust settles under gravity and falls to the bottom of the dust collection cylinder 1, exiting through the drain pipe 7. Simultaneously, the waterproof motor 64 starts and drives the impeller 63 to rotate at high speed within the mounting plate 62. The foam generated within the dust collection cylinder 1 is broken by the rectangular holes on the surface of the defoaming disc 61, and some of the foam enters the mounting plate 62. Under the lateral shearing force of the impeller 63, the foam breaks down and liquefies, falling through the rectangular holes on the surface of the defoaming disc 61.

[0024] In summary, the natural gas compressor intake dust removal structure, through the combined use of the cyclone dust collector 2 and the spray assembly 3, performs centrifugal dust removal and spray dust reduction on the air entering the inner cavity of the dust collector cylinder 1 from the intake pipe 5. At the same time, under the action of the defoaming assembly 6, the sewage bubbles at the bottom of the inner cavity of the dust collector cylinder 1 are eliminated, thereby achieving the purpose of centrifugal and spray dual-stage dust removal and effectively preventing foam generation.
