Description
Technical field
The utility model belongs to heat recovery field, specifically, is a kind of residual neat recovering system for coke oven flue.
Background technology
In the coke oven of the highly energy-consuming such as Coal Chemical Industry, coke industry, stack gases does not much reclaim, directly discharge.Some unit is directly installed on waste-heat oven in coke oven flue collector, waste-heat oven maintenance or break down and affect the use of whole coke oven, thus affect normal production work.
Above-mentioned waste-heat oven is that simple fire tube heat recovery steam generator carries out stack gases recovery, and because heat exchange efficiency is poor, toxic emission temperature is still more than 200 degree, and this shows that a large amount of residual heat resources do not obtain effective recycling.
Because common fire tube (tubulation) formula waste heat boiler exists stifled ash mostly, burn into heat exchange efficiency is low and be difficult for the disadvantages such as maintenance, cause very large loss to Business Economic Benefit.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of heat exchange efficiency high, be convenient to that installation and repairing, life-span are long, the residual neat recovering system for coke oven flue of the stifled ash of dust stratification, anticorrosion resistance to erosion.
Technical solutions of the utility model are achieved in that
A kind of residual neat recovering system for coke oven flue, comprise coke oven, waste-heat oven, flue collector and chimney, described coke oven connects chimney by flue collector, a bypass flue in parallel on described flue collector, this bypass flue is installed waste-heat oven, on the bypass flue of this waste-heat oven inlet end, adjustable butterfly valve is installed, switching mode butterfly valve 8 is installed on the bypass flue of this waste-heat oven outlet side, on the bypass flue between switching mode butterfly valve and waste-heat oven, blower fan is installed, homophony nodal pattern butterfly valve is installed on the flue collector between adjustable butterfly valve and switching mode butterfly valve.
And, described waste-heat oven comprises drum, casing and heat pipe, one dividing plate is laterally installed in described casing, casing is separated into upper heat release section, lower endotherm section by described dividing plate, on this casing, heat release section upper end connects drum by tedge and down-comer respectively, this dividing plate installs the many heat pipes that vertical spacing arranges, and this heat pipe outer wall is installed fin.
Advantage of the present utility model and good effect are:
1, native system is connected in parallel on waste-heat oven on bypass flue, and at flue collector and bypass flue, control valve is installed respectively, and coke oven and waste-heat oven are not interfere with each other, and has effectively ensured the normal work of system.
2, this waste-heat oven adopts heat pipe-type, has greatly improved heat transfer coefficient.
3, by installing and separate, effectively prevent the leakage of boiler circuit in waste-heat oven, guaranteed the safe operation of system, thoroughly solved equipment leakage problem.
4, native system is simple in structure, design science is reasonable, have heat exchange efficiency high, be convenient to that installation and repairing, life-span are long, the feature of the stifled ash of dust stratification, anticorrosion resistance to erosion.
Brief description of the drawings
Fig. 1 is system connection layout of the present utility model;
Fig. 2 is the structural representation of the utility model waste-heat oven.
Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
For a residual neat recovering system for coke oven flue, as shown in Figure 1, comprise coke oven 1, waste-heat oven 5, flue collector 2 and chimney 9, described coke oven connects chimney by flue collector.
Innovative point of the present utility model is:
A bypass flue 6 in parallel on described flue collector, this bypass flue is installed waste-heat oven, adjustable butterfly valve 3 is installed on the bypass flue of this waste-heat oven inlet end, switching mode butterfly valve 8 is installed on the bypass flue of this waste-heat oven outlet side, blower fan 7 is installed on the bypass flue between switching mode butterfly valve and waste-heat oven, homophony nodal pattern butterfly valve 4 is installed on the flue collector between adjustable butterfly valve and switching mode butterfly valve.
Described waste-heat oven is heat pipe waste-heat oven, and its structure as shown in Figure 2, comprises drum 10, casing 14 and heat pipe 12, and a dividing plate 13 is laterally installed in described casing, and this dividing plate installs the many heat pipes that vertical spacing arranges, and this heat pipe outer wall is installed fin; Casing is separated into upper heat release section, lower endotherm section by described dividing plate, can effectively prevent the leakage of water-steam system, in the time of operation, even if heat pipe one end is corroded, can not cause carbonated drink to go here and there mutually, guaranteed the safe operation of system, thoroughly solved equipment leakage problem; On this casing, heat release section upper end is delivered to drum by tedge 16 by steam water interface, and this drum is delivered to heat release section bottom on casing by down-comer 11 by condensed water.
The operation principle of this waste-heat oven is:
High-temperature flue gas 15 is flowed through after the lower endotherm section of casing heat is passed to upper heat release section by heat pipe, the vapour, the aqueous mixtures that on this, in heat release section, produce arrive drum through tedge, after concentrating separation, control in steam valve output, the condensed water producing in drum is delivered to the upper heat release section of water tank through down-comer again.Like this because heat pipe constantly sends heat to the water that is positioned at heat release section on water tank, and complete basic vapour, water circulation by rising and the decline of outside vapour, waterpipe, reach hot fluid cooling, and be converted into the object of steam.
