Description
Technical field
The utility model relates to a kind of diesel exhaust gas pipeline used heat utilized device.
Background technique
No matter be stationary diesel engine or marine diesel engine, all users directly insert atmosphere with exhaust duct, all ignored contained heat in the waste gas of discharging, especially marine diesel engine, power own is big, air displacement is big, stream time is long, heat is also many in the waste gas, if use the supply that full ship can both guarantee hot water in 24 hours.The energy waste that causes thus and not talking, in order to guarantee the hot water of the full ship of regular supply, all need to dispose separately the electric heating water tank on the ship, the power of heater is generally wanted about tens kilowatts, strengthened the load of generator set virtually, the consumption of fuel oil causes great waste also along with increase to resource.
Summary of the invention
In order to address the above problem, the utility model provides a kind of diesel exhaust gas pipeline used heat utilized device, the waste-gas heat that diesel engine is discharged fully utilizes, and converts waste-gas heat the heat energy of fresh water to by heat exchange, and the temperature of fresh water can reach boiling point.
The utility model is by the following technical solutions: a kind of diesel exhaust gas pipeline used heat utilized device, and it comprises housing and exhaust stack, exhaust stack is positioned at housing, is provided with hot water cavity between described exhaust stack and the housing; Described housing is provided with the entery and delivery port that communicates with hot water cavity, and described housing is provided with inlet, outlet in two ends up and down, and inlet, outlet forms the gas channel that communicates with exhaust stack.
Described exhaust stack is made up of up and down two end plates and plurality of rows tracheae, and two end plates is welded on the interior two ends up and down of housing respectively and enclosure interior is sealed; Be evenly distributed with some on the described end plate and the corresponding through hole of outlet pipe quantity, the size of through hole is corresponding with the diameter of outlet pipe, and outlet pipe is fixed on the through hole and with inlet, outlet and communicates; The top of described hot water cavity is provided with safety valve; Described housing outer surface is provided with thermal insulation layer; Described housing outer surface is provided with base; Described housing bottom is provided with the relief outlet that communicates with hot water cavity.
The utlity model has following beneficial effect: be provided with hot water cavity between exhaust stack and housing in the utility model, discharge from the air outlet at last through the outlet pipe of exhaust stack after entering from suction port from the high-temp waste gas in the gas exhaust piping, during gas process outlet pipe hot water cavity is heated, thereby the heat of waste gas is converted to the heat energy of fresh water, reach the purpose that used heat utilizes, reduce the workload of electric water heater simultaneously, reduced the working load of generator set, thereby reduced the loss of the energy.Being provided with thermal insulation layer at the outer surface of housing can be incubated the high temperature that can prevent frame simultaneously again to the hot water of hot water cavity and scald the staff.The top of hot water cavity is provided with safety valve, and safety valve can be adjusted release pressure according to actual conditions.
