Dry-method bag-type dust collecting is mainly to utilize weaving cotton cloth or filtering the grit in felt trapping dusty gas of various voidages.But in the converter coal gas dry-method bag-type dust collecting technology actual motion in existing, having topmost problem is because filter bag material is limited, and the gas temperature that can bear is generally no more than 260 DEG C, and excess Temperature will burn out filter bag.
The measure of existing adjusting gas temperature has:
(1) before bag-type dust, add spray cooling equipment; This method is applicable under the condition of the higher and long-term continuous and steady operation of gas temperature, once gas temperature is lower, can cause the knot of filter bag to stick with paste, and affects filter bag ventilation property;
(2) with the form of tubular heat exchanger to the coal gas processing of lowering the temperature; The great advantage of the method is exactly that flue gas can directly not contact with water or other heat-exchange working mediums, there will not be filter bag knot to stick with paste phenomenon, and waste heat that can recovered flue gas.But common tubular heat exchanger, belongs to snakelike arrangement, and atmospheric drag is large, and easy to wear.
Therefore, be necessary to provide a kind of novel waste-heat recovery device, overcome large, the easy to wear shortcoming of common tubular heat exchanger resistance.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of device for recovering waste heat of high-temperature flue, and this device can reduce the consumption of water to greatest extent, and reclaims the heat of high-temperature flue gas.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of device for recovering waste heat of high-temperature flue, it is characterized in that comprising interchanger, described interchanger is provided with water-in and water outlet, described water-in is placed in lower end and is communicated with lower collecting box, described lower collecting box is connected with drum downtake, described water outlet is placed in upper end and is communicated with upper header, described upper header is connected with drum upcast, the outer wall of interchanger is provided with gas approach and exhanst gas outlet, gas approach is placed in upper end, and exhanst gas outlet is placed in lower end.
Said structure is described further, and the internal arrangement of described interchanger has flow deflector, forms bending exhaust gases passes between flow deflector and interchanger, and this exhaust gases passes is communicated with gas approach and exhanst gas outlet.
Said structure is described further, and described flow deflector has downward small angle inclination setting.
Said structure is described further, and described interchanger is cross flow type tubular heat exchanger, and its inner heat transfer tube is for being staggered.
Said structure is described further, and the lower end of described interchanger is provided with ash-valve.
High-temperature flue gas of the present utility model is entered by the gas approach of interchanger, with water and the water vapor generation heat exchange in interchanger, the flue gas being cooled enters next process system through the exhanst gas outlet of interchanger, in flue gas, the dust of larger particles, because action of gravity sinks to interchanger bottom, is regularly discharged through ash-valve.In flue gas heat release, water in interchanger and water vapor import upper linked box after absorbing heat, through drum upcast, enter in drum, after carbonated drink centrifugation, the underheat water in drum enters the lower collecting box of interchanger through drum downtake, water all should be assigned in the heat transfer tube of interchanger by lower collecting box, absorb the heat of high-temperature flue gas, thereby realize the heat exchange of water cycle.
The beneficial effect that adopts technique scheme to produce is:
(1) flue gas is through interchanger, and flue-gas temperature reduces, and working medium heat absorption produces steam, thus the high-temperature residual heat of recovered flue gas;
(2), in cooling, dust larger in flue gas is regularly discharged through ash-valve because action of gravity deposits to interchanger bottom, makes the dust in flue gas obtain preliminary removal, also plays the provide protection to bottom process system.
