Description
Technical field
The utility model is related to drying tower tail gas heat quantity in exhaust waste heat recovery device, particularly precipitated silica production
Retracting device.
Background technology
Precipitated silica is a kind of widely used fine chemical product, is mainly used in tire, rubber, silicon rubber, modeling
The fields such as material, coating, food, medicine, feed.Existing precipitated silica production process slurry is pumped into drying by screw rod
Tower, the clean high-temperature hot air provided with hot-blast stove after atomization carries out heat exchange, by the moisture evaporation in slurry, steam and thing
Material through sack cleaner collection material, by air-introduced machine pumped through smoke stack emission by tail gas.The defect of presence is：Due to tail gas after drying
Discharge capacity is big, and exhaust temperature is about 80-90 DEG C, and the heat content that it contains is at a relatively high, causes energy waste.Therefore will be if by the portion
Part thermal source is recycled, and will save a large amount of energy consumptions.
The content of the invention
The purpose of this utility model is to provide drying tower tail gas heat quantity retracting device in a kind of precipitated silica production, will
Heat recovery and utilization in white carbon drying tower tail gas, reaches energy-saving effect.
To realize object above, drying tower tail gas heat quantity retracting device includes in the production of the utility model precipitated silica
Drying tower, sack cleaner, air-introduced machine, tail gas heat quantity recovery tower, hot wash-water groove, washing water pump, chamber-type press filter and connection
Pipeline；The bottom of the drying tower is connected by pipeline with sack cleaner, and the top of the sack cleaner is connected by pipeline
Connect the entrance of air-introduced machine；The outlet of air-introduced machine accesses the bottom in tail gas heat quantity recovery tower by pipeline, and pipe end outlet is upward, should
Top in tail gas heat quantity recovery tower is provided with the shower being connected with running water, and the outlet at bottom of tail gas heat quantity recovery tower is by pipe
Road is connected to hot wash-water groove entrance, and makes the outlet at bottom absolute altitude of tail gas heat quantity recovery tower higher than hot wash-water groove entrance；From washing
The scrubbed water pump of bottom introduction pipe for washing hot water storgae is followed by chamber-type press filter.
The spray tube end is provided with uniform downward spray structure.
Drying tower tail gas heat quantity retracting device is drawn by the tail gas exported in drying tower in above-mentioned precipitated silica production
One tail gas heat quantity recovery tower is installed after blower fan, using uniform spray equipment, hollow-spraying-tower is used to reduce resistance, connect through vapour-liquid
The water temperature of the water for reclaiming after touch can be improved to 50 DEG C or so, and the hot water of recovery is applied to the filter press washing of white carbon black production
With.Due to washing the raising of water temperature, washing speed is improve, reduce leaching requirement, reduced and use steaming to improve rate of washing
The quantity of steam that vapour heating washings are consumed, realizes energy-saving purpose.
Benefit measuring and calculating of the present utility model is as follows：
The recycling of tail gas heat quantity improves to 50 DEG C pressure filtration washing water from 20 DEG C, equivalent to can reduce steam consumption
600kg/h, then can reduce steam consumption in year is：
0.6 ton × 24h × 300 day=4320 ton steam, 5 tons of steam, coals per ton are produced based on 650 yuan, then by coal per ton
Coal amount can be saved is:
Ten thousand yuan/ton of 4320/5 × 650=56.1, i.e., it is 56.1 ten thousand yuan that can reduce every year with coal expense.
Brief description of the drawings
Fig. 1 is drying tower tail gas heat quantity retracting device structural representation in the production of the utility model precipitated silica.
Reference：Drying tower 1, sack cleaner 2, air-introduced machine 3, tail gas heat quantity recovery tower 4, hot wash-water groove 5, washing
