Description
Technical field
The utility model relates to large ship main frame tail gas waste heat utilizing device, and a kind of using waste heat from tail gas preparing fresh water device, belong to technical field of ships specifically.
Background technology
Development along with science and technology, the manufacturing tonnage of boats and ships is also increasing, especially aspect big fishing vessel, tonnages up to ten thousand have been reached, generally this type of large-scale seagoing vessel goes to sea and once needs at least 1 year, so the Freshwater resources on ship are deficienter, often regularly replenish by the corresponding tender in sea, needing so huge storage area and buying expenses high, is a urgent problem.
Summary of the invention
The purpose of this utility model is to provide a kind of large ship main frame tail gas waste heat utilizing device.
Problem to be solved in the utility model is the deficiency that existing ocean fishing vessel Freshwater resources lack.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
The utility model proposes a kind of large ship main frame tail gas waste heat utilizing device, comprise vapor pipe, conducting strip, water reservoir, induction pipe, main frame, condenser, rising pipe, gas-liquid separating valve, header tank, pipe tunnel and horizontal pipeline, main frame is provided with vapor pipe, on the vapor pipe inside and outside wall, conducting strip is installed, the vapor pipe overcoat has water reservoir, water reservoir is connected with condenser by induction pipe, condenser is connected with gas-liquid separating valve by rising pipe, and gas-liquid separating valve is connected with header tank by pipe.
Described condenser comprises pipe tunnel and horizontal pipeline, is welded with 4-8 bar horizontal pipeline between two pipe tunnels; Described condenser is arranged on the hull plate outer side, directly contacts with seawater.
Be plugged with fluffy wire in described pipe tunnel and horizontal pipeline, the wire material is scandium yittrium alloy material.
The utility model has the advantages that: can directly sea water desaltination be used by using waste heat from tail gas, energy-conserving and environment-protective greatly reduce the cost of long range fishing, should have the wide market space.

Fig. 2 is the structural representation of condenser;
In figure: 1, vapor pipe 2, conducting strip 3, water reservoir 4, induction pipe 5, main frame 6, condenser 7, rising pipe 8, gas-liquid separating valve 9, header tank 10, pipe tunnel 11, horizontal pipeline.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the utility model proposes a kind of large ship main frame tail gas waste heat utilizing device, comprise vapor pipe 1, conducting strip 2, water reservoir 3, induction pipe 4, main frame 5, condenser 6, rising pipe 7, gas-liquid separating valve 8, header tank 9, pipe tunnel 10 and horizontal pipeline 11, main frame 5 is provided with vapor pipe 1, on vapor pipe 1 inside and outside wall, conducting strip 2 is installed, increases the heat utilization efficiency of tail gas; Vapor pipe 1 overcoat has water reservoir 3, water reservoir 3 is connected with condenser 6 by induction pipe 4, induction pipe 4 interfaces are positioned at the top of water reservoir 3, condenser 6 is connected with gas-liquid separating valve 8 by rising pipe 7, gas-liquid separating valve 8 is connected with header tank 9 by pipe, gas-liquid separating valve 8 is for separating of fresh water and part water vapor, and when only having the interior water level of rising pipe 7 high, water just can enter header tank 9, and not so gas has directly emitted from rising pipe 7 opening parts.
Described condenser 6 comprises between pipe tunnel 10 and 11, two pipe tunnels 10 of horizontal pipeline and is welded with 4-8 bar horizontal pipeline 11, consists of parallel high efficiency and heat radiation condenser, and its condensation efficiency is 3 times of common series-connected helical formula.
Described condenser 6 is arranged on the hull plate outer side, directly contacts with seawater, and with the raising condensation effect of maximum efficiency, and cost simple in structure is low.
Be plugged with fluffy wire in described pipe tunnel 10 and horizontal pipeline 11, the wire material is scandium yittrium alloy material, to increase internal water steam and contact area wiry, its condensation efficiency than boring improves more than 3 times as can be known by experiment, and materials has special good conduction effect and resistance of oxidation, elasticity, contact area is also reliable.
Principle of work of the present utility model, by after tail gas heating, water vapor enters rising pipe 7 after by efficient condenser 6 when the seawater in water reservoir 3, finally enter header tank 9, just become drinkable fresh water, greatly improved energy utilization rate, also guaranteed the water supply on the ship.
