The utility model is applied in coking using horizontal water-tube cooler to the cooling of coke-stove gas, and raw gas passes through gas-liquid Temperature is generally at 80 DEG C~85 DEG C after separator, and contains a large amount of tar gas and steam, and for the ease of conveying, coal gas need to be in cross 20~25 DEG C are further cooled in pipe cooler 23.
In the utility model, cooling tube is adopted as the design of U-shaped pipe 24, is divided into two parts, upper and lower part, respectively at the winter It and summer use, to keep factory energy saving, reduce security risk and reduce environmental pollution.
Coke-fired furnace as shown in Figure 2, the block furnace generally erect, is supported using rigid body, coal charge downlink in erectting furnace, Coal is moved down by furnace top can be divided into three sections: successively dryer section 3, retort section 6, quenching section 17;In upper section, that is, dryer section 3, Coal degree of drying reaches combustion standard, opens first of gate 91, makes to fall in first of gate 91 under dry coal, to first After filling full coal in road gate 91, second gate 92 is opened, coal is made to fall into retort section 6, closes twice gate, control later The production capacity of stove prevents 6 gas of retort section from going upward to dryer section 3;Guarantee that coal being capable of the first banister above opening It is more closely knit behind the door to be filled, it ensure that in coal dropping process and the raw gas of retort section effectively suppressed.
Coal falls into retort section 6 and burns, and is located at firing tunnel in coking furnace and air in quirk and burns, and generates raw gas uplink, By the pipeline of top, raw gas is exported.
Coal is heated to 500 DEG C~750 DEG C, and after full combustion, the red burnt ram 14 that passes through goes downwards to spoke in water-cooling wall 7 Heat exchange is penetrated, so that the temperature of coke is reduced to 150 DEG C~200 DEG C, and a large amount of vapor generated are successively passed through by steam outlet pipe 8 Blower 34 and waste heat boiler 33 enter power plant 32 and generate electricity.
After water cooled wall 7 is cooling, third road control valve 93 is opened, coal is fallen on down in quenching section 17 completely, closes third Road control valve 93 sprays the coal in quenching section 17 by the nozzle of circulation semi-coke wastewater and cycle flue gas, makes coke The temperature and quality of charcoal reach criterion of acceptability;Flue gas after quenching heat exchange is again introduced into electricity by top smoke outlet tube 39 Factory 32 is recycled after cooling;The 4th control valve 94 is opened, will be fallen under coke on transporter 12, finally fall into coke bin 13 Interior, transporter 12 selects belt conveyer.
Coke furnace gas running body process as shown in Figure 2: the raw gas generated in coke-fired furnace, by raw gas channel 4 into Enter in gas-liquid separator 20, separated through gas-liquid separator 20, the temperature of coal gas is at 80 DEG C~85 DEG C and containing a large amount of burnt Oil and steam, are up to gas in horizontal water-tube cooler 23, and liquid downlink reaches the floating roof formed coke oil on ground by pipeline In ammonium hydroxide defecator 22, further separate.After the impurity in floating roof type tar ammonia defecator 22 purifies, light oil and heavy oil It is emitted in dregs of fat pond 37, and the semi-coke wastewater in tar ammonia defecator 22 is circulated back to quenching by ammonium hydroxide inlet tube 16 The quenching section 17 of furnace carries out quenching.
The gas for reaching horizontal water-tube cooler 23, by the further cooling and purifying to coal gas, the waste water of generation, the miscellaneous arrival of oil It is precipitated in wastewater disposal basin 35, semi-coke wastewater returns in tar ammonia defecator 22, and the coal gas of generation enters electrical tar precipitator 26, is allowed to Tar and scrubbed gas are isolated, tar goes downwards to tar storage by the way that the tar outlet pipe 29 of 26 lower section of electrical tar precipitator is arranged in 31, coal gas is up to the storage of gas storage tank 30 by the way that the gas outlet tube 28 of 26 upper section of electrical tar precipitator is arranged in.
The coal gas for reaching gas storage tank 30 is divided into three parts, first part pass through be arranged in be connected at the top of it melt down coal Feed channel 19 returns in retort section 6, mix help with air and burns, wherein the outlet and destructive distillation of firing tunnel in coking furnace pipeline 19 Combustion fan 5 is provided between section 6;Second part is pipelined to power plant 32, helps to generate electricity, Part III stays in tank Generation economic interests for sale.
The a large amount of vapor generated in water-cooling wall 7 is sent to power plant 32 and is generated electricity by blower 34 and waste heat boiler 33.
The flue gas that power plant 32 generates enters quenching section 17 and semi-coke wastewater one by power plant's outlet flue 36 and triple valve 42 It rises and carries out quenching, extra nitrogen after the completion of last quenching returns to power plant by smoke outlet tube 39 after the filtering of filter 11 Outlet flue 36 be recycled after discharging or entering the cooling of power plant 32.
Coal gas has most of steam and tar to be condensed, is generated in the cooling procedure in horizontal water-tube cooler 23 Water impurity reach in wastewater disposal basin 35, further precipitate, and be sent in floating roof type tar ammonia defecator 22 by pipeline, institute's shape At coal gas electrical tar precipitator 26 entered by gas inlet pipe 25 carry out process below.
