背景技术Background technique
轻烃燃气发生系统是一种以液态轻烃（主要成分为C5）为原料，经过专用气化设备将液态轻烃转化为混空燃气，从而提高燃烧效率以实现对现有能源的充分利用。现有的燃料气的发生装置基本为鼓泡式，即将空气鼓入到燃气发生罐内，通过气泡在油料中上升的过程中，油与气泡接触，油分子进入气泡形成可以燃烧的混空轻烃燃气。为保证燃气的质量（热值），常用办法是采用增加气体与油的接触面积和增加气泡在油的停留时间，并配合辅助加热，已达到燃油充分气化的效果，此工艺已经在工业中逐渐推广并应用。The light hydrocarbon gas generation system uses liquid light hydrocarbons (mainly composed of C5) as raw materials, and converts liquid light hydrocarbons into air-mixed gas through special gasification equipment, so as to improve combustion efficiency and realize full utilization of existing energy. The existing fuel gas generating device is basically a bubbling type, that is, the air is blown into the gas generating tank, and when the bubbles rise in the oil, the oil contacts the bubbles, and the oil molecules enter the bubbles to form a combustible air-mixed light hydrocarbon gas. In order to ensure the quality (calorific value) of fuel gas, the common method is to increase the contact area between gas and oil and increase the residence time of bubbles in the oil, and cooperate with auxiliary heating to achieve the effect of full gasification of fuel oil. This process has been used in the industry Gradually promote and apply.
但是现有的制漆工艺无论设备和过程怎么变化，总是摆脱不了基本的“将气体鼓入油料内后是气体与油料自然混合，然后再进行混空燃气”的形式。这种形式已经经过工艺和设备的不断改进能够产生稳定的燃气，但是空气与油料的混合效率较低；或者为了提高混合效率而增加设备的复杂程度和/ 或能源的消耗。However, no matter how the existing paint-making process changes in equipment and process, it can't get rid of the basic form of "gas is blown into the oil, then the gas and oil are naturally mixed, and then mixed with air and gas". This form has been continuously improved in technology and equipment to produce stable gas, but the mixing efficiency of air and oil is low; or to increase the complexity of the equipment and/or energy consumption in order to improve the mixing efficiency.

制气工艺为：开启真空泵后负压缓冲箱形成负压，控制器控制各负压管电磁阀打开，对应的补气电磁阀关闭，将各负压箱的空气室内的气体抽出，使燃气室内的压强减小，油气混合管内形成负压吸入空气，同时油气混合管上的孔洞同时吸入恒液位储油罐内的液态轻烃，液态轻烃在油气混合管内与空气混合并气化形成混空燃气进入负压箱的燃气室内，当负压箱的空气室内负压达到0.1~0.14MPa时，压力感应器传递信号给控制器，控制器控制负压管电磁阀关闭，补气电磁阀打开使空气室补入空气，将燃气室内的混空燃气挤出外送；压力感应器检测到空气室内恢复常压后传递信号给控制器，控制器再次控制重复上述操作；恒液位储油罐内的液态轻烃减少后，控制器实时的打开补油管电磁阀补入液态轻烃使油气混合管的中心位置始终处于液态轻烃液面以下45cm~55cm。The gas production process is as follows: After the vacuum pump is turned on, the negative pressure buffer box forms a negative pressure, the controller controls the solenoid valves of each negative pressure pipe to open, and the corresponding air supply solenoid valve closes, and the gas in the air chamber of each negative pressure box is pumped out to make the gas chamber As the pressure decreases, negative pressure is formed in the oil-gas mixing tube to inhale air, and at the same time, the holes on the oil-gas mixing tube suck in the liquid light hydrocarbons in the constant liquid level oil storage tank at the same time, and the liquid light hydrocarbons are mixed with air in the oil-gas mixing tube and gasified to form a mixture. The air gas enters the gas chamber of the negative pressure box. When the negative pressure in the air chamber of the negative pressure box reaches 0.1~0.14MPa, the pressure sensor transmits a signal to the controller, and the controller controls the solenoid valve of the negative pressure pipe to close and the solenoid valve for supplementary air to open. Fill the air chamber with air, squeeze out the mixed gas in the gas chamber and send it out; the pressure sensor detects that the normal pressure in the air chamber returns to the normal pressure and sends a signal to the controller, and the controller controls and repeats the above operations again; the constant liquid level oil storage tank After the liquid light hydrocarbon in the tank is reduced, the controller will open the solenoid valve of the oil supply pipe in real time to replenish the liquid light hydrocarbon so that the center of the oil-gas mixing pipe is always 45cm~55cm below the liquid light hydrocarbon level.
本发明工艺的最主要特点是无需将空气分散以后再进行收集，而是在负压条件下直接将适量的轻烃吸入到空气中，因为负压和空气流动均能加速气化，使得轻烃在流动的过程中快速气化，这样不但大大的减小系统的体积、降低能耗，还提高了燃气的制备效率。本发明在油气混合管开设小的孔洞，形成毛细现象，在油气混合管内常压状态时利用轻烃于孔洞的毛细作用防止轻烃进入管内，在油气混合管内负压状态时，配合液位形成的适当液压，轻烃被吸入管内，由于管壁的疏油作用，轻烃会快速的形成小而分散的小油滴，从而能随空气流动而快速气化。The most important feature of the process of the present invention is that it is not necessary to disperse the air and then collect it, but directly sucks an appropriate amount of light hydrocarbons into the air under negative pressure conditions, because both negative pressure and air flow can accelerate gasification, so that the light hydrocarbons Rapid gasification in the process of flow, which not only greatly reduces the volume of the system, reduces energy consumption, but also improves the efficiency of gas preparation. The invention opens small holes in the oil-gas mixing pipe to form capillary phenomenon, and uses the capillary action of light hydrocarbons in the holes to prevent light hydrocarbons from entering the pipe under normal pressure in the oil-gas mixing pipe. Due to the proper hydraulic pressure, light hydrocarbons are sucked into the pipe. Due to the oleophobic effect of the pipe wall, light hydrocarbons will quickly form small and dispersed oil droplets, which can be quickly gasified with the air flow.
对于恒液位储油罐的液位可以通过恒液位储油罐的重力实时监测控制，也可以通过罐内的液位检测器控制，方式多种多样，只要能及时控制器传递信号给满足油气混合管所在的深度稳定均可使用。The liquid level of the constant liquid level oil storage tank can be monitored and controlled in real time by the gravity of the constant liquid level oil storage tank, or it can be controlled by the liquid level detector in the tank. It can be used at any depth where the oil-gas mixing pipe is stable.
负压管电磁阀、各补气电磁阀、各补油管电磁阀和各压力感应器可以连接同一个控制器，也可以各自连接控制器，只要能满足本发明的功能需求即可。The negative pressure pipe solenoid valve, each air supply solenoid valve, each oil supply pipe solenoid valve and each pressure sensor can be connected to the same controller, or can be connected to the controller separately, as long as they can meet the functional requirements of the present invention.
优选的，所述的油气混合管的进气端连接空气过滤器。进气端设置过滤器，能够更好的保证空气质量。Preferably, the air intake end of the oil-air mixing pipe is connected with an air filter. A filter is installed at the intake end to better ensure air quality.
优选的，所述的燃气供给管路上设有稳压储气箱。系统制得的燃气先进入稳压储气箱能够保证供气时压力稳定，先后的燃气在此处进一步混合，使得燃气的质量也更稳定。Preferably, a pressure-stabilizing gas storage tank is provided on the gas supply pipeline. The gas produced by the system first enters the pressure-stabilized gas storage tank to ensure stable pressure during gas supply, and the successive gases are further mixed here, making the quality of the gas more stable.
优选的，所述的油气混合管由进气端到另一端向上倾斜，油气混合管与水平面的倾斜角a的大小为10°~15°。油气混合管以此角度倾斜，能够在油气混合管的前后形成渐弱的液压，使油气混合管内随着混合路程的变短，空气中轻烃的逐渐饱和，而进入管内的液态轻烃也逐渐减少，保证制气效率的同时保证进入的液态轻烃能够完全的气化。Preferably, the oil-gas mixing pipe is inclined upward from the air intake end to the other end, and the inclination angle a between the oil-gas mixing pipe and the horizontal plane is 10°-15°. The oil-gas mixing pipe is inclined at this angle, which can form a gradually weakening hydraulic pressure before and after the oil-gas mixing pipe, so that as the mixing distance in the oil-gas mixing pipe becomes shorter, the light hydrocarbons in the air are gradually saturated, and the liquid light hydrocarbons entering the pipe are gradually saturated. Reduce the gas production efficiency while ensuring that the incoming liquid light hydrocarbons can be completely gasified.
优选的，所述的油气混合管上孔洞的密度为2~5个/cm2。本系统设计的孔洞密度配合孔洞的大小能够保证液态轻烃的进入量，保证制气效率的同时保证进入的液态轻烃燃烧质量。Preferably, the density of holes on the oil-gas mixing tube is 2-5 holes/cm 2 . The hole density and size of the holes designed in this system can ensure the incoming amount of liquid light hydrocarbons, ensure the gas production efficiency and ensure the combustion quality of the incoming liquid light hydrocarbons.
优选的，所述的油气混合管的管壁厚度为2 mm ~3.5mm。优选的管壁厚度能够配合孔洞的大小形成良好的毛细作用，使得油气混合管内没有负压时，液态轻烃不会进入油气混合管内，影响下次启动时的燃气质量。Preferably, the wall thickness of the oil-gas mixing tube is 2 mm to 3.5 mm. The optimal wall thickness can match the hole size to form a good capillary effect, so that when there is no negative pressure in the oil-gas mixing tube, liquid light hydrocarbons will not enter the oil-gas mixing tube, which will affect the gas quality at the next start-up.
实时补油管连接处于高位的液态轻烃储罐。The real-time oil replenishment pipe is connected to the high-level liquid light hydrocarbon storage tank.
所述的空气室内负压达到0.1~0.12MPa时，压力感应器传递信号给控制器，控制器控制负压管电磁阀关闭。优选的负压条件能够保证油气混合管内进入适量的轻烃，从而既能够完全气化，有充分的保证燃烧质量。When the negative pressure in the air chamber reaches 0.1-0.12MPa, the pressure sensor transmits a signal to the controller, and the controller controls the solenoid valve of the negative pressure pipe to close. The optimal negative pressure condition can ensure that an appropriate amount of light hydrocarbons enter the oil-gas mixing tube, so that it can be completely gasified and the combustion quality can be fully guaranteed.
所述的恒液位储油罐内的液态轻烃减少后，控制器实时的打开补油管电磁阀补入液态轻烃使油气混合管的中心位置始终处于液态轻烃液面以下50cm~52cm。优选的液位能够形成更加合适的液压，保证油气混合管内进入适量的轻烃，从而既能够完全气化，有充分的保证燃烧质量。After the liquid light hydrocarbons in the constant liquid level oil storage tank are reduced, the controller opens the solenoid valve of the oil replenishment pipe in real time to replenish the liquid light hydrocarbons so that the center of the oil-gas mixing pipe is always 50cm-52cm below the liquid light hydrocarbon level. The optimal liquid level can form a more suitable hydraulic pressure and ensure that an appropriate amount of light hydrocarbons enter the oil-gas mixing pipe, so that it can be completely gasified and fully ensure the combustion quality.
与现有技术相比，本发明的一种负压型液化燃气制备工艺所具有的有益效果是：本faming提供一种利用负压管路制备混空燃气的工艺。最主要特点是无需将空气分散以后再进行收集，而是在负压条件下直接将适量的轻烃吸入到空气中，因为负压和空气流动均能加速气化，使得轻烃在流动的过程中快速气化，这样不但大大的减小系统的体积、降低能耗，还提高了燃气的制备效率。本发明在油气混合管开设小的孔洞，形成毛细现象，在油气混合管内常压状态时利用轻烃于孔洞的毛细作用防止轻烃进入管内，在油气混合管内负压状态时，配合液位形成的适当液压，轻烃被吸入管内，由于管壁的疏油作用，轻烃会快速的形成小而分散的小油滴，从而能随空气流动而快速气化。恒液位储油罐内的液态轻烃通过控制器实时的补入，保持油气混合管外的液压恒定，从而保证产气质量稳定。本工艺简单，能耗低，液态轻烃以被流动气流包裹的小液滴的形式气化，气化速率大大的提高，产气效率高，燃气质量稳定。Compared with the prior art, the beneficial effect of the negative-pressure liquefied gas preparation process of the present invention is that the faming provides a process for preparing air-mixed gas by using a negative-pressure pipeline. The most important feature is that it is not necessary to disperse the air before collecting it, but directly inhale an appropriate amount of light hydrocarbons into the air under negative pressure, because both negative pressure and air flow can accelerate gasification, so that the light hydrocarbons are in the process of flowing Medium and fast gasification, which not only greatly reduces the volume of the system, reduces energy consumption, but also improves the efficiency of gas preparation. The invention opens small holes in the oil-gas mixing pipe to form capillary phenomenon, and uses the capillary action of light hydrocarbons in the holes to prevent light hydrocarbons from entering the pipe under normal pressure in the oil-gas mixing pipe. Due to the proper hydraulic pressure, light hydrocarbons are sucked into the pipe. Due to the oleophobic effect of the pipe wall, light hydrocarbons will quickly form small and dispersed oil droplets, which can be quickly gasified with the air flow. The liquid light hydrocarbons in the constant liquid level oil storage tank are replenished in real time through the controller to keep the hydraulic pressure outside the oil-gas mixing pipe constant, thereby ensuring stable gas quality. The process is simple, low energy consumption, and the liquid light hydrocarbons are gasified in the form of small droplets wrapped by the flowing air flow, the gasification rate is greatly improved, the gas production efficiency is high, and the gas quality is stable.
