技术领域Technical Field
本发明涉及一种用于垃圾焚烧发电的汽水循环系统，属于电站锅炉设备技术领域。The invention relates to a steam-water circulation system for garbage incineration power generation, belonging to the technical field of power station boiler equipment.
背景技术Background Art
随着中国城市化水平的不断提高，城市生活垃圾不断增多，垃圾焚烧锅炉应运而生并在热力发电领域得到了广泛的应用。由于垃圾焚烧产生的烟气中所含有的氯化物盐类会引起垃圾焚烧锅炉受热面产生高温腐蚀（高温腐蚀的活跃区为400-600℃），因此目前垃圾焚烧余热锅炉的过热蒸汽温度通常设计在450℃以下，而450℃以下的主蒸汽用于发电时，汽轮机的出力和发电效率较低。为了提高汽轮机的出力和发电效率，同时避免垃圾焚烧余热锅炉受热面出现高温腐蚀，现有的解决方案是：在垃圾焚烧余热锅炉外部设置用于主蒸汽二次加热的沼气加热炉，通过沼气加热炉受热面对主蒸汽进行二次加热。这种由垃圾焚烧余热锅炉、沼气加热炉及汽轮机共同组成的汽水循环系统（如附图1所示）在运行时，由垃圾焚烧锅炉5加热给水产生的450°C过热蒸汽通过固定于沼气加热炉9烟道内的二次加热过热器6进行二次加热，主蒸汽二次加热后升温至480℃以上再送入汽轮机7，以提高汽轮机7的出力和发电效率，做功后的蒸汽在凝汽器8成为凝结水回到凝泵1，垃圾焚烧锅炉5的给水入口前端设置给水加热器2和蒸汽除氧器3，给水加热器2和蒸汽除氧器3由汽轮机7提供热源，来自凝泵1的给水（凝结水＋补水）通过给水加热器2加热并经过蒸汽除氧器3除氧，再经给水泵4送入垃圾焚烧锅炉5，通过给水加热器2加热和蒸汽除氧器3除氧后的给水水温不低于130°C以避免垃圾焚烧锅炉5低温段受热面发生低温腐蚀。With the continuous improvement of China's urbanization level, the amount of urban domestic waste has continued to increase. Waste incineration boilers have emerged and have been widely used in the field of thermal power generation. Since the chloride salts contained in the flue gas generated by waste incineration will cause high-temperature corrosion on the heating surface of the waste incineration boiler (the active zone of high-temperature corrosion is 400-600℃), the superheated steam temperature of the waste incineration waste heat boiler is usually designed to be below 450℃. When the main steam below 450℃ is used for power generation, the output and power generation efficiency of the steam turbine are low. In order to improve the output and power generation efficiency of the steam turbine and avoid high-temperature corrosion on the heating surface of the waste incineration waste heat boiler, the existing solution is to set a biogas heating furnace for secondary heating of the main steam outside the waste incineration waste heat boiler, and perform secondary heating on the main steam through the heating surface of the biogas heating furnace. When the steam-water circulation system (as shown in FIG1 ) composed of the waste incineration waste heat boiler, the biogas heating furnace and the steam turbine is in operation, the 450°C superheated steam generated by the waste incineration boiler 5 heating the feed water is secondary heated by the secondary heating superheater 6 fixed in the flue of the biogas heating furnace 9. The main steam is secondary heated to a temperature of more than 480°C and then sent to the steam turbine 7 to improve the output and power generation efficiency of the steam turbine 7. The steam after work becomes condensate in the condenser 8 and returns to the condensate pump 1. A feedwater heater 2 and a steam deaerator 3 are arranged at the front end of the feedwater inlet of the waste incineration boiler 5. The feedwater heater 2 and the steam deaerator 3 are provided with heat sources by the steam turbine 7. The feedwater (condensate + make-up water) from the condensate pump 1 is heated by the feedwater heater 2 and deoxygenated by the steam deaerator 3, and then sent to the waste incineration boiler 5 through the feedwater pump 4. The water temperature of the feedwater after being heated by the feedwater heater 2 and deoxygenated by the steam deaerator 3 is not lower than 130°C to avoid low-temperature corrosion of the heating surface of the low-temperature section of the waste incineration boiler 5.
上述汽水循环系统在用于垃圾焚烧发电时虽然有效地解决了主蒸汽温度较低导致汽轮机出力和发电效率降低的技术问题，但还存在以下缺陷：Although the above steam-water circulation system effectively solves the technical problem of reduced turbine output and power generation efficiency due to low main steam temperature when used for waste incineration power generation, it still has the following defects:
1、给水加热器2和蒸汽除氧器3需从汽轮机7抽取蒸汽作为给水除氧和加热的热源，降低了汽轮机7的出力和发电效率。1. The feed water heater 2 and the steam deaerator 3 need to extract steam from the steam turbine 7 as a heat source for deoxygenating and heating the feed water, which reduces the output and power generation efficiency of the steam turbine 7.
2、沼气加热炉的排烟温度高达400℃，造成了能源的浪费。2. The exhaust gas temperature of the biogas heating furnace is as high as 400℃, resulting in energy waste.
发明内容Summary of the invention
本发明主要在解决现有技术所存在的汽轮机出力和发电效率较低、沼气加热炉排烟温度较高运行不经济的技术缺陷，提供一种汽轮机出力和发电效率较高、沼气加热炉排烟温度较低运行较经济的用于垃圾焚烧发电的汽水循环系统。The present invention mainly aims to solve the technical defects of the prior art, namely, low turbine output and power generation efficiency, and high exhaust temperature of a biogas heating furnace, which is not economical to operate, and to provide a steam-water circulation system for garbage incineration power generation, which has high turbine output and power generation efficiency, low exhaust temperature of a biogas heating furnace, and is more economical to operate.

二次加热过热器6固设于沼气加热炉9烟道的高温段；The secondary heating superheater 6 is fixedly arranged in the high temperature section of the flue of the biogas heating furnace 9;
给水加热器2位于沼气加热炉9烟道的低温段，除氧蒸发器10位于给水加热器2和二次加热过热器6之间；The feedwater heater 2 is located in the low temperature section of the flue of the biogas heating furnace 9, and the deoxygenation evaporator 10 is located between the feedwater heater 2 and the secondary heating superheater 6;
蒸汽除氧器3包括除氧头31，入口与除氧头31出口连接的汽包32，除氧头31入口与给水加热器2出口连接，汽包32出口与给水泵4入口连接；The steam deaerator 3 comprises a deaerator head 31, a drum 32 whose inlet is connected to the outlet of the deaerator head 31, the inlet of the deaerator head 31 is connected to the outlet of the feed water heater 2, and the outlet of the drum 32 is connected to the inlet of the feed water pump 4;
除氧蒸发器10通过连接管与汽包32相连接，汽包32内给水通过除氧蒸发器10与烟气换热并在除氧蒸发器10与汽包32之间形成热循环。The deoxygenation evaporator 10 is connected to the steam drum 32 through a connecting pipe. The feed water in the steam drum 32 exchanges heat with the flue gas through the deoxygenation evaporator 10 and forms a heat cycle between the deoxygenation evaporator 10 and the steam drum 32 .
当机组运行时，来自凝汽器8的45℃左右凝结水及补水经过凝泵1进入给水加热器2通过与烟气换热加热到100℃左右后进入除氧头31进行除氧，除氧后的给水进入汽包32，汽包32内给水通过除氧蒸发器10与烟气换热升温至130°C并产生蒸汽，汽包32内蒸汽上升至除氧头31用于给水除氧，除氧升温后的给水通过给水泵4送入垃圾焚烧锅炉5，在垃圾焚烧炉5吸收热量后形成450℃的主蒸汽，主蒸汽通过二次加热过热器6加热到480~540℃后送入汽轮机7做功发电，做功后的蒸汽经过凝汽器8形成凝结水并加入补水后回到凝泵1，形成热力循环。When the unit is running, the condensate at about 45°C and make-up water from the condenser 8 enter the feed water heater 2 through the condensate pump 1, and are heated to about 100°C by heat exchange with the flue gas, and then enter the deaerator head 31 for deoxygenation. The deoxygenated feed water enters the steam drum 32. The feed water in the steam drum 32 is heated to 130°C by heat exchange with the flue gas through the deoxygenation evaporator 10 and generates steam. The steam in the steam drum 32 rises to the deaerator head 31 for deoxygenation of the feed water. The deoxygenated and heated feed water is sent to the waste incineration boiler 5 through the feed water pump 4, and forms main steam of 450°C after absorbing heat in the waste incinerator 5. The main steam is heated to 480~540°C through the secondary heating superheater 6 and then sent to the turbine 7 to generate power. The steam after work passes through the condenser 8 to form condensate and returns to the condensate pump 1 after adding make-up water, forming a thermal cycle.
在机组运行过程中，除氧蒸发器10和给水加热器2在沼气加热炉9烟道内与烟气换热，大大降低了烟气温度，沼气加热炉9的排烟温度最低能够降到80℃左右，极大地提高了能源利用率，因而沼气加热炉9的运行更为经济；同时，给水加热器2和除氧蒸发器10通过与沼气加热炉9内烟气换热获取给水升温和除氧所需要的热量，避免了从汽轮机7抽汽，较好地提升了汽轮机7的出力和发电效率。During the operation of the unit, the deaerator 10 and the feed water heater 2 exchange heat with the flue gas in the flue of the biogas heating furnace 9, which greatly reduces the flue gas temperature. The exhaust temperature of the biogas heating furnace 9 can be reduced to about 80°C at the lowest, which greatly improves the energy utilization rate, and thus the operation of the biogas heating furnace 9 is more economical; at the same time, the feed water heater 2 and the deaerator 10 obtain the heat required for feed water heating and deoxygenation by exchanging heat with the flue gas in the biogas heating furnace 9, thereby avoiding steam extraction from the steam turbine 7 and greatly improving the output and power generation efficiency of the steam turbine 7.
当然上述附图和实施例仅为了用于解释和说明本发明，并不能作为本发明的不当限定。凡本领域技术人员依据本发明做出等效调整与变化而得到的技术方案均落入本发明的保护范围。Of course, the above drawings and embodiments are only used to explain and illustrate the present invention, and cannot be used as improper limitations of the present invention.
