Waste heat recycling device

Abstract

The invention discloses a waste heat recycling device. In cold winter, a preheating device and a waste heat recycling device are additionally arranged on a tractor body, after water in a matched watertank is heated to a proper temperature through an electric heater of the preheating device, a water pump of the preheating device drives hot water to circulate at a rear side bent pipe, a right sidebent pipe and a front side bent pipe, and therefore a diesel engine body is heated; the temperature of the engine body rises, the viscosity of engine oil in the engine body is reduced, the resistancemoment of the engine oil is reduced, the temperature rises, the fit clearance of engine parts returns to normal, the lubricating condition is improved, and smooth starting is achieved. After a dieselengine is normally started, the preheating device is stopped, and a tractor normally runs; by means of waste heat emitted by a water tank and an exhaust pipe of the diesel engine, a water jacket of the water tank of the diesel engine, a water jacket of the exhaust pipe and corresponding matched pipelines are additionally arranged, a rear drive shaft of the tractor serves as a power source of a gear pump of the waste heat recycling device, water circularly flows through the water jacket of the water tank of the diesel engine and the water jacket of the exhaust pipe to absorb heat, the heat is continuously brought to a driver seat coil pipe and a backrest coil pipe, and therefore the environment temperature of a driver seat and a backrest of the tractor is increased, the driving work environment becomes relatively comfortable, the fatigue of a driver is relieved, and long-distance driving safety is ensured.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery and utilization, in particular to a waste heat recovery and utilization device. Background technique [0002] In the cold winter, tractor drivers keep sitting for a long time to work, and the hips and waist cannot be exercised, which makes the driver more prone to fatigue in cold conditions and poses a great driving safety hazard; the difficulty of cold start of diesel engines in winter is also a problem that needs to be solved urgently. In winter, the external temperature decreases, the viscosity of the engine oil increases, and the fluidity becomes poor, which is an important reason for the increase of the starting torque of the diesel engine. On the other hand, the waste heat emitted by the water tank and exhaust pipe of the diesel engine is lost in vain and cannot be effectively recycled. How to add a heat source to improve the driver's working environment under the guidance of ene...

Problems solved by technology

[0002] In the cold winter, tractor drivers keep sitting for a long time to work, and the hips and waist cannot be exercised, which makes the driver more prone to fatigue in cold conditions and poses a great driving safety hazard; the difficulty of cold start of diesel engines in winter is also a problem that needs to be solved urgently. In winter, the external temperature decreases, the viscosity of the engine oil increases, and the fluidity becomes poor, which is an important reason for the increase of the starting torque of the diesel engine.

On the other hand, the waste heat emitted by the water tank and exhaust pipe of the diesel engine is lost in vain and cannot be effectively recycled. How to add a heat source to improve the driver's working environment under the guidance of energy saving and consumption reduction? How to take effective measures to preheat the engine before starting , and how to recover the waste heat of the diesel engine itself and improve the working conditions of the tractor driver. Patent application number CN201520898651.7 discloses a waste heat recovery device. Recycling, but the heating of the driver cannot be realized

In order to overcome this difficulty, it is urgent to design a waste heat recovery device based on the tractor itself to solve the problem of tractor waste heat reuse
