A new type of integrated water-cooled intake and exhaust device

Abstract

The invention belongs to the technical field of engine air intake and exhaust devices, and particularly relates to a novel integrated water-cooling air intake and exhaust device. The novel integrated water-cooling air intake and exhaust device comprises an air intake channel, an exhaust pulse channel and a cooling water chamber used for cooling. A water intake joint and a water discharge joint are arranged in the cooling water chamber. The air intake channel and the exhaust pulse channel are also arranged in the cooling water chamber. An air intake flange is arranged at one end of the air intake channel and is connected with an air compressor of a water-cooling turbocharger. A plurality of intake air collectors connected with an air intake of an explosion-proof diesel engine are connected to the air intake channel. An exhaust flange connected with a turbine of the water-cooling turbocharger is arranged at one end of the exhaust pulse channel. A plurality of exhaust collectors connected with an exhaust port of the explosion-proof diesel engine are connected to the exhaust pulse channel. The air intake and exhaust device is unique and novel in structure, safe, reliable and capable of meeting downhole explosion-proofing requirements, and is a quite ideal air intake and exhaust device for explosion-proof diesel engines under coal mine wells.

Description

technical field [0001] The invention belongs to the technical field of engine intake and exhaust devices, and in particular relates to a novel integrated water-cooled intake and exhaust device. Background technique [0002] Explosion-proof rubber-tyred vehicles have become the main equipment for trackless auxiliary transportation in coal mines. As the main power source of explosion-proof rubber-tyred vehicles, explosion-proof diesel engines are more and more used in underground explosion-proof rubber-tyred vehicles. At present, there are many engine intake pipes and exhaust pipes on one side of explosion-proof rubber-tyred vehicles, and there are many problems: 1. The air intake and exhaust do not meet the explosion-proof requirements of coal mines, and the exhaust is not cooled, causing its surface temperature to exceed MT990- The surface temperature required by the 2006 "General Technical Conditions for Mining Explosion-proof Diesel Engines" is 150°C; 2. After the water j...

Problems solved by technology

At present, there are many engine intake pipes and exhaust pipes on one side of explosion-proof rubber-tyred vehicles, and there are many problems: 1. The air intake and exhaust do not meet the explosion-proof requirements of coal mines, and the exhaust is not cooled, causing its surface temperature to exceed MT990- The surface temperature required by the 2006 "General Technical Conditions for Mining Explosion-proof Diesel Engines" is 150°C; 2. After the water jacket is added to the exhaust manifold, the shape increases and the intake air pipe interferes. Long-term operation will cause intake or exhaust leakage; 3. After the intake air is supercharged, the intake air temperature is high, resulting in NQ in the exhaust gas X increased, worsened emissions
