Abstract
The utility model mainly relates to the chemical industry, and discloses a recycling system for waste heat of spray drying tail gas. The recycling system is mainly applied to heating cold water by the aid of the spray drying tail gas in the white carbon black manufacturing industry. The recycling system is characterized in that a high-pressure induced draft fan is connected between a bag-type dust collector and a tail gas heating tower, and a plurality of spray heads are arranged in the tail gas heating tower and are connected with a cold water inlet; a hot water outlet of the tail gas heating tower is connected with a hot water recycling tank, the hot water recycling tank is connected with a washing material pump, and the washing material pump is connected with a plate and frame filter. The outer end of the cold water inlet is connected with a circulating water pump of a cold water storage pond. The recycling system has the advantages that the temperature of water can reach about 40 DEG C, the hot water washing time is earlier than the cold water washing time by 1.5 hours, power consumption can be reduced by 1980Kw every day, and power can be saved by 712800Kw in every year; the washing efficiency can be doubled at least, the washing time can be saved, the productivity can be improved, the stability of the quality of products can be guaranteed, and a thorough sodium sulfate washing effect and energy saving and efficacy enhancing effects can be realized.
Description
technical field
The utility model relates generally to chemical industry, is more mainly used in white carbon black production industry utilization spraying dried tail gas the spraying dried tail gas waste heat recycling system of cool water heating.
Background technology
In prior art, white carbon washing adopts cold water to wash material always, and washing time is long, and sodium sulphate is removed not thorough in water-washing process, and electrical conductivity is too high, causes product colour bad.
The utility model adopts a kind of spraying dried tail gas waste heat retracting device that cold water is carried out to heat exchange, white carbon in process of production, by technological requirement, the 3rd section of operation has one to be water-washing process, completely reacted material is squeezed in sheet frame, pass through water-washing process, sodium sulphate remaining in filter cake is washed, make electrical conductivity in filter cake reach process stipulation and require (in 150 μ s/cm), washing temperature best in water-washing process should be the most suitable at 30 ~ 40 ℃, because washing filter cake hourly water consumption is larger, water consumption per hour is at 170 cubes, especially winter, ground water temperature was at 2 ℃ above freezing, washing time is just longer, be difficult to reach prewashing effect, the suspension temperature that cause is squeezed in sheet frame is higher, greatly about 80 ~ 90 ℃ of left and right, the cold water of advancing by leaps and bounds has played the instantaneously cooled effect of material, cause washing time to extend, impact washing effect, affect product quality.So utilize spray-dired using waste heat from tail gas cool water heating, utilize water pump to play circulation, cold water enters hot water and goes out, make water temperature reach 40 ℃ of left and right, hot water flows automatically in Recovery of the hot water tank, and hot water shifts to an earlier date 1.5 hours than the washing time of cold water, save power consumption 1980Kw every day, annual economize on electricity 712800Kw.Washing efficiency has improved more than 1 times, has played the effect of the water-saving and electricity-saving of economizing on coal.
Utility model content
The purpose of this utility model is mainly to solve above-mentioned deficiency and a kind of spraying dried tail gas waste heat recycling system that can utilize recovery waste heat heating water of providing
Technical solution of the present utility model is: a kind of spraying dried tail gas waste heat recycling system, it is characterized in that high-pressure suction fan is connected between sack cleaner and tail gas heating tower, in tail gas heating tower, have a plurality of spray heads, spray head is connected with cold water inlet; Tail gas heating tower hot water outlet is connected with Recovery of the hot water tank, and Recovery of the hot water tank connects washing product pump, and washing product pump is connected with plate filter.Cooling water inlet outer end is connected with cold water storage pond water circulating pump.
Dust-removal cloth-bag tail gas, 150 ℃ of left and right, utilizes high-pressure suction fan that heat energy is converted into hot water, utilizes water pump to carry out water circulation, has reached the object of heating.So utilize spray-dired using waste heat from tail gas cool water heating, utilize water pump to play circulation, cold water enters hot water and goes out, make water temperature reach 40 ℃ of left and right, hot water flows automatically in Recovery of the hot water tank, and hot water shifts to an earlier date 1.5 hours than the washing time of cold water, by producing 20000 tons of calculating per year, save power consumption 1980Kw every day, annual economize on electricity 712800Kw.Washing efficiency has improved more than 1 times, has played the effect of the water-saving and electricity-saving of economizing on coal.
The utility model has the advantages that: the hot water of returning is mainly used in the washing of filter cake in sheet frame, and hot water wash material advantage is very many, has saved washing time, improved production capacity, guaranteed the stable of product quality, it is more thorough that sodium sulphate is washed, and reached the effect of energy efficiency.
Below structure accompanying drawing is described in further detail embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the utility model structure schematic diagram of arranging.
The specific embodiment
Referring to Fig. 1, parts title is as follows: sack cleaner 1, high-pressure suction fan 2, tail gas heating tower 3, Recovery of the hot water tank 4, cold water store up pond 5, water circulating pump 6, washing product pump 7, spray head 8, water inlet 9, hot blast import 10, enter cold water outlet 11, remove sheet frame 12.
Referring to Fig. 1, spraying dried tail gas waste heat recycling system adopts high-pressure suction fan 2 to be connected between sack cleaner 1 and tail gas heating tower 3, has a plurality of spray heads 8 in tail gas heating tower 3, and spray head 8 is connected with cold water inlet 9; Tail gas heating tower 3 hot water outlets are connected with Recovery of the hot water tank 4, and Recovery of the hot water tank 4 connects washing product pump 7, and washing product pump 7 is connected with plate filter.Cooling water inlet outer end is connected with the water circulating pump 6 in cold water storage pond 5.
In water-washing process, mainly to utilize residual neat recovering system to reach the process cool water heating, it is the waste heat that utilizes the dust-removal cloth-bag of sack cleaner 1, with high-pressure suction fan 2, heat energy is transported to tail gas heating tower 3, external cold water enters cold water storage pond 5, by water circulating pump 6, cold water is squeezed into tail gas heating tower 3 and make cool water heating by eight spray heads 8, hot water gravity flow Recovery of the hot water tank 4 is squeezed into and in sheet frame, is carried out water-washing process by washing product pump 7 again, make water temperature reach 40 ℃, washing efficiency improves more than 1 times, has reached energy-saving and cost-reducing optimum efficiency.Utilize the annual accumulative total of this recycling system to be total to more than approximately 450,000 yuan yuan of power cost savings, economize on coal 449 tons approximately 230,000 yuan.
