BOG 回收机组（卸车小霸王）BOG recovery unit
卸车结束把槽车余压抽干净：闪蒸 BOG 经回热、压缩后回储罐或送管网，一台机组把卸车与回收两件事做完。Pulls the last pressure out of the trailer: flash BOG is reheated, compressed and returned to the tank or the network — unloading and recovery in one package.
产品概述Product overview
槽车卸完还留 1–3 公斤压力，这部分 BOG 以往直接放空。按 0.1 MPa 余压折算约 80 kg LNG，3 公斤余压折 200 多千克液相、合 348 方气态天然气；三天一卸的站，一年放掉的量就抵得上一台机组。Trailers arrive with 1–3 bar left: at 0.1 MPa that is about 80 kg of LNG, at 3 bar over 200 kg liquid, roughly 348 m³ of gas — vented, it is the price of the unit every year.
两个模式走一套管路：卸车时槽车 BOG 经回热器升温，压缩后进储罐；回收时储罐蒸发气经回热、压缩回到槽车或管网。进口往复式压缩机、回热器、空冷器与油气分离集成在一个箱体内，接管接线即可投用。Two modes, one piping set: during unloading the trailer BOG is reheated, compressed and pushed into the tank; during recovery the tank boil-off goes back to the trailer or the network.
防爆电控箱就地显示进出口压力与温度；排气温度过高、线圈温度过高、入口温度过低自动保护，油位过高、油位过低、油位异常与润滑油压异常各自停机，不靠人盯表。An Ex panel shows inlet and outlet pressure and temperature; discharge, coil and low-inlet temperature are protected, with separate trips for oil level and oil pressure.
结构组成What is in the cabinet
核心优势Why this design
- 卸得干净：余压抽到 1 公斤以下，槽车不带压返厂。Clean unloading: pressure pulled below 1 bar before the trailer leaves.
- 回收见钱：放掉的 BOG 变成能计量、能结算的气。Recovered value: vented BOG becomes metered, billable gas.
- 保护齐备：温度三道、润滑四项，异常自动停机。Protection first: three temperature and four lubricant trips.
- 成柜即装：落地接管接线，不占现场工期。Cabinet-ready: land it, connect it, run it.
四件做到位，设备才站得稳Four things done right
调压器、切断阀、过滤器按工况选型，出厂做全性能测试，压力稳得住。
管路、阀组与仪表厂内一次组对、试压，现场接上进出口就能投用。
超压切断与放散、温度与浓度监控、自动运行，异常先切后报。
每台带检验试验状态标识、检验记录与检验报告，跟设备一起交到现场。

以上为该系列出厂数据；排气量与压力等级按站点卸车频次、储罐容积与槽车余压选定，一台机组只做一个规格，参数以合同技术文件为准。Data is for this series; capacity and pressure class are selected on unloading frequency, tank volume and trailer residual pressure.
适用工况Typical duties
适合什么工况，什么情况不适用Where it fits, and where it does not
这套设备适合Best for
- 卸车频次高的 LNG 站，余压放空的量能直接折成气费LNG stations unloading often, where vented residual pressure is real money
- 槽车返厂仍带 1 公斤以上余压、装货方要求泄压Trailers leaving with over 1 bar, where the loader requires depressurising
- 储罐蒸发气长期外排、站内需要回罐或回网Tanks venting boil-off that should go back to storage or the network
- 场地与工期紧，需要成柜落地、接管接线即用Tight site and schedule, needing a cabinet that runs on hook-up
需要提前确认的边界Check before ordering
- 回收是否经济要按卸车次数与液量算，次数太少不划算Economics depend on unloading frequency and litres per load
- 进出口接口需与槽车、储罐一致，转换接头要提前确认Couplings must match trailer and tank; adaptors confirmed in advance
- 现场需划分防爆区域并保证通风与电源容量Hazardous area classification, ventilation and power capacity required
标准配置Standard configuration
以上为常规配置，实际随机组按工况与用户管网条件确定，可按需增减。Standard scope shown; final scope is set by duty and network conditions, and can be adjusted.
