Background technique
At present; Homemade 12V190 type has only 40.5% heat energy to be converted into effective mechanical output when being the work of routine diesel engine; 59.5% described heat exchanger (3) comprises respectively the end plates (9) that are connected with anechoic chamber (8) with smoke-box (2); Two end plates (9) and sidewall constitute airtight chamber, and a plurality of connection smoke-boxes (2) and the heat exchanging tube (10) of anechoic chamber (8) the following technical problem of determining is installed between two end plates (9): 1, the flue gas recovering device can not form resistance to diesel smoke.2, the diesel smoke carbon distribution is to the heat conducting influence of device for recovering tail gas.3, recovering medium selects for use.In view of the above problems, restricted the development of this technical field.And drilling crew's production in winter uses boiler that drilling equipment is carried out anti-freezing and heat-insulating; There are two subject matters in this heat preserving mode: 1, consume a large amount of energy; According to statistics: drilling crew's winter heating phase on average will burn about 300 tons of coal, water consumption 2000 sides, cause the mass energy wave useless and to the pollution of environment, and operating cost is higher.2, freeze easily behind the boiler water vapour condensation.At present, a large amount of heat energy of diesel smoke tail gas can not well be used, and need consume the preventing freeze in winter insulation that a large amount of coals, water resources carry out drilling equipment on the other hand, and this is a very outstanding problem.This extremely is necessary the using waste heat from tail gas of motor is used, reaches the purpose of energy-saving and emission-reduction, protection environment.
The model utility content
The purpose of the utility model is to provide a kind of engine tail gas waste-heat heat-exchanger rig; Diesel engine vent gas heat energy is reclaimed and utilizes; The hot air that utilizes heat exchange to obtain substitutes the boiler steam drilling equipment is incubated; Realize the recovery and reuse of diesel exhaust resource, reach the purpose of energy-saving and emission-reduction, protection environment.
The purpose of the utility model realizes through following technical proposals:
The engine tail gas waste-heat heat-exchanger rig; Comprise the flue gas inlet, smoke-box, heat exchanger, anechoic chamber and the smoke exhaust port that connect successively; Also comprise air intake pipe and be installed in the blower fan on the air intake pipe; The output terminal of blower fan gets in the heat exchanger, and heat exchanger is provided with opening, and the hot air air outlet tube is installed on opening.The heat exchanger flue gas inlet is installed on the exhaust pipe of motor; The high-temperature tail gas of motor gets into flue gas inlet; Tail gas gets in the smoke-box through flue gas inlet; In smoke-box, form stable High Temperature Gas body source, and evenly get in the heat exchanger, get into through the tail gas after the heat exchange and discharge from smoke exhaust port after the anechoic chamber abates the noise; Produce suction after being installed in the fan starting on the air intake pipe simultaneously; Cool air is sucked and delivers in the heat exchanger from air intake pipe; The flow direction of cool air and the motor exhaust flow direction in heat exchanger is opposite; Cool air absorbs behind the high-temperature tail gas temperature and raises and discharge from heat outlet, is transported in the facility environment that needs heat tracing.To cool air, himself energy reduces high-temperature tail gas with heat transfer, becomes the lower tail gas of temperature and discharges.In the whole process, with the high-temperature tail gas of motor through the hot air after the heat exchange to the drilling equipment heat tracing, replaced the use of boiler; Simultaneously, the mode with respect to the water heating not only can play the effect of heating; And can be when needs use heat tracing; The persistency of having avoided the water heating with can not discontinuity, cost reached the reduction of discharging purpose of energy saving well below the water mode of heating.
Described heat exchanger comprises respectively the end plates that are connected with the anechoic chamber with smoke-box, and two end plates and sidewall constitute airtight chamber, and the heat exchanging tube of a plurality of connection smoke-boxes and anechoic chamber is installed between two end plates.Say that further as the further improvement of the utility model, heat exchanger comprises the circulation passage of high-temperature tail gas and the circulation passage of cool air; Two passages are separate, carry out heat exchange through separated tube wall therebetween, therefore; Adopt two end plates and sidewall to constitute airtight cavity body structure, its two end plates are parallel to each other, and a plurality of heat exchanging tubes are installed between two end plates; Separate and parallel between the heat exchanging tube, the space between the heat exchanging tube promptly forms the circulation passage of cool air, and cool air is a heat transferring medium; The free air space of high-temperature tail gas and the free air space of cool air are isolated each other; The flow direction of cool air is opposite with the flow direction of high-temperature tail gas, forms current difference, helps the carrying out of heat exchange.
Two deflection plates are installed in said heat exchanger at least, and said deflection plate is parallel with the end plates of heat exchanger, and any two adjacent deflection plates are connected on the opposing side of heat exchanger sidewall.Further say; In order to increase the area of heat exchange, through two or more deflection plates are installed, a plurality of continuous passages of tail gas stream passage cutting formation that deflection plate is inner with heat exchanger on the heat exchanger sidewall; The total length of these passages is greater than the length of heat exchanging tube; Make the cool air time mobile extend, help the efficient of heat exchange, heat transferred cool air as much as possible with respect to high-temperature tail gas.
On described smoke-box, anechoic chamber and hot air air outlet tube, thermometer is installed all.As the further improvement of the utility model, on smoke-box, anechoic chamber and hot air air outlet tube, thermometer is installed all, be used to measure each regional air temperature, to reach the convenient purpose of using.
The utility model compared with prior art has following advantage and beneficial effect:
1 the utility model engine tail gas waste-heat heat-exchanger rig, with the high-temperature tail gas of motor through after the heat exchange, with the air of high temperature to the drilling equipment heat tracing; Replaced the use of boiler, the mode with respect to the water heating not only can play the effect of heating; And can be when needs use heat tracing; The persistency of having avoided the water heating with can not discontinuity, cost heats well below water, reached the reduction of discharging purpose of energy saving;
2 the utility model engine tail gas waste-heat heat-exchanger rigs are installed a plurality of heat exchanging tubes between two end plates, separate and parallel between the heat exchanging tube; Space between the heat exchanging tube promptly forms the circulation passage of cool air; The tube wall of heat exchanging tube is a heat transfer space, and the free air space of high-temperature tail gas and the free air space of cool air are isolated each other, and the flow direction of cool air is opposite with the flow direction of high-temperature tail gas; Form current difference, help the carrying out of heat exchange;
