Description

The energy saver of manufactured by chemical material carrier

Technical field:

The present invention relates to chemical industry and produce a kind of energy saver of molecular sieve, drier, activated alumina, catalyst carrier.

Background technology:

Molecular sieve, drier, activated alumina, the catalyst carrier of producing before the present invention are the production technology production of continuing to use French Standard, it by the pneumatic conveying drying operation, take off operation, granulating working procedure and activation procedure soon and form, each operation is all wanted a showing tremendous enthusiasm stove heat supply, its device energy-wasting height, investment is big, and the oil gas consumption is too high, long flow path, production capacity is little, and discharging waste heat energy is big, and waste heat is recycling not.Package unit need dispose four hot-blast stove overlapping investment.

Summary of the invention:

Purpose of the present invention is exactly to provide a kind of energy saver of manufactured by chemical material carrier for overcoming above-mentioned deficiency.

Core of the present invention is: only with a hot-blast stove supply hot blast, the residual air heat energy of operation discharging recycles and reuses by thermal energy converter 9 device of a whole set of production line, reaches energy-saving and cost-reducing purpose.It is characterized in that: produce high-temperature hot-air with a hot-blast stove 1, and form heating plant with the waste heat that reclaims, its heating plant is after carrying out hot blast and waste heat proportioning by hot air duct 18 and waste heat pipeline 13 and heat control valve 2 and thermal energy converter 9, form by parallel connection, by pipeline 13, the desired hot blast of 18 supply production processes, it is that waste heat is added hot-air by thermal energy converter 9 that the residual air hot blast reclaims, it is combustion-supporting and reach energy recovery purpose of energy saving and effect that heated air is sent into hot-blast stove, and waste heat recovery is connected with hot air duct 18 by thermal energy converter 9 and waste heat pipeline 13.

The invention has the advantages that: reduce investment outlay, device technique is simplified, energy-saving effect is obvious.Former a whole set of production line will be equipped with the quadruplet hot-blast stove, and every cover hot-blast stove investment is 140,000 a yuan/platform cover, adds up to hot-blast stove to invest 560,000 yuan, after the employing invention, only needs a hot blast furnace gauge that strengthens some thermal capacity to invest 160,000 yuan, 400,000 yuan of saving investment meters.

Energy conservation and consumption reduction effects: 900 ℃ of original production hot wind supply temperature, 470 ℃ of discharging (going out) EGTs, after adopting the technology of the present invention heat exchange to reclaim, discharging (going out) EGT is 70 ℃, reclaims the heat energy utilization rate and is calculated as follows: establish hot blast heat absorption capacity coefficient K KJ/m ³

If extraction flow Q arranges m ³/ h

If heat supply air quantity Q is for m ³/ h

Heat energy recovery rate μ %

Because of Q arranges for ≈ Q

$\mathrm{\μ}=\frac{(470-70)}{900}\×100\%=44\%$

Energy-saving efficiency is 44%.

Embodiment:

Raw material 15 add steam flow drying ovens 3 oven dry be raw-material adhere to moisture content after; again the raw material of oven dry is added pulverizer 5 and be broken into fine powder; fine powder added take off stove 6 soon and slough that molecule becomes the activated feedstock powder in conjunction with moisture content in the fine powder raw material; after 7 granulations of active powder process comminutor; become finished product after adding activation furnace 8 activation by health reaction back again, through the packing warehouse-in.

Natural gas produces hot blast for hot-blast stove 1 by combustion gas surge tank 17 constant pressure air feedings, hot blast is by warm-air pipe 18 and waste heat pipeline 12 and each operation hot blast of heat control valve 2 independent dispensings (the pneumatic conveying drying stove takes off stove, activation furnace etc. soon), and waste gas residual heat enters atmosphere after reclaiming through heat exchanger 9 heat exchange again.
