Embodiment Construction

[0027] Such as figure 1 As shown, the fuel processing system provided by the present invention includes a fuel pipeline with a predetermined length, which is divided into a gasification heat exchange pipeline 38 and a decompression treatment pipeline 39 from the beginning to the end along the flow direction of the fuel; The beginning of the gasification heat exchange pipeline 38 communicates with the external fuel storage device 3 , and the end of the decompression treatment pipeline 39 communicates with the external combustion device 12 .

[0028] Along the flow direction of the fuel, an emergency cut-off valve 21 , a gasifier 24 and a heat exchanger 26 are arranged in series on the gasification heat exchange pipeline 38 . A safety valve 17 , a tee 40 and a pressure gauge 20 are arranged in sequence between the fuel storage device 3 and the emergency cut-off valve 21 . The three ports of the tee 40 communicate with the fuel storage device 3 , the emergency cut-off valve 21 a...

Abstract

The invention provides a fuel treating system and natural gas well-washing and wax-cleaning equipment. The fuel treating system disclosed by the invention comprises a fuel pipeline; the fuel pipeline comprises a gasification heat exchange pipeline and a decompression treatment pipeline which are sequentially communicated with each other along the flowing direction of fuel; the tail end of the decompression treatment pipeline is used for being connected with a combustion device and the initial end of the gasification heat exchange pipeline is used for being connected with an external fuel storage device; the gasification heat exchange pipeline is serially connected with a safety valve, an emergency cut-off valve, a gasifier and a heat exchanger; the heat exchanger is provided with a hot fluid inlet and a hot fluid outlet; the hot fluid inlet is used for being connecting with a hot water device and the hot fluid outlet is used for being connected with a water inlet pipeline of a water pump; and the decompression treatment pipeline is provided with a primary decompression valve. According to the invention, by arranging gasification heat exchange and primary decompression, liquefied natural gas with a pressure value and a temperature value which meet combustion requirements can be guaranteed to be output. The natural gas well-washing and wax-cleaning equipment using the fuel treating system disclosed by the invention uses the liquefied natural gas, reduces the quality and the volume of a whole vehicle and can effectively save the working cost.

Description

technical field [0001] The invention relates to a fuel processing system and natural gas well washing and wax removal equipment using the fuel processing system. Background technique [0002] The existing well washing and wax removal equipment in the market all use light diesel oil as fuel. Due to the high price of light diesel oil, the use cost of well washing and wax removal equipment is relatively high. The patent "gas decompression system and natural gas wax removal vehicle" (CN101628546A and CN201546841U) applied by our unit discloses a natural gas decompression system and a wax removal vehicle using the natural gas decompression system. The gas decompression system is mainly suitable for compressed natural gas , The storage pressure of LNG is generally 0.6MPa, and this patented technology cannot be used. However, in order to meet the heat requirements for well cleaning and paraffin removal equipment, the number of compressed natural gas cylinders must be at least thre...
