The invention provides an exhaust and supercharging device with an exhaust gas energy adjusting function, and relates to the technical field of exhaust systems of gas engines (gasengines) and independent gas / air supercharging. The exhaust and supercharging device comprises an exhaust manifold, a gas turbocharger, an air turbocharger, a regulating valve and an exhaust gas energy regulating valve. Manifold branch flanges on the exhaust manifold are connected with air cylinder exhaust ports of an engine; an air flange at one end of the exhaust manifold is connected with the air turbocharger, a gas flange at the other end of the exhaust manifold is connected with the regulating valve, and the regulating valve is connected with the gas turbocharger; and the opening degree of the regulating valve is controlled by a regulating valve controller to adjust the flow and pressure of supercharged gas, and the actual requirements of the engine are met. According to the exhaust and supercharging device, the problem about gas supercharging of the gas engine is solved, and the adaptability of the gas engine to gas is enhanced; and meanwhile, the adopted exhaust manifold alleviates the problem of exhaust pressure fluctuation, and the running performance of the engine is improved.
Description
technical field [0001] The invention belongs to the technical field of exhaust systems of gas engines (gas engines) and gas / air independent pressurization, and in particular relates to an exhaust and pressurization device with energy regulation of exhaust gas. Background technique [0002] Low calorific value gas (such as gas, biogas, coal gas, etc.) is a natural resource that can be used as fuel for gas engines, but it must reach a certain pressure before it can be used. In this field, there are two ways to pressurize low calorific value gas: one is to use various compressors to compress the gas alone; the other is to mix the gas and air in a certain proportion first, and then use the The booster boosts the pressure. The first way is too complicated because of the compression equipment and its auxiliary devices, the investment is large, and the reliability is low. The second way is the more common technical way at present. However, in practical applications, because the ...
