Abstract
A kind of Chinese medicine is calcined and fried exhaust gas purification system, including the exhaust pipe being connect with each machine for stir-frying Chinese medicine and stir-fry medicine pan exhaust outlet, exhaust pipe is connected to flue gas purification system, and the flue gas purification system includes purifying column, the purified gas evacuated tube that connect with purifying column, the blower in purified gas evacuated tube, the upper pool with purifying column piping connection；It is equipped with interim evacuated tube on the pipeline before flue gas purification system, is equipped with air-valve in interim evacuated tube, between interim evacuated tube and flue gas purification system.The utility model purification system small investment, operational administrative is easy, and environmental benefit is obvious, high to the purification efficiency of sulfur dioxide, reaches 97% or more to the purification efficiency of dirt in flue gas.
Description
Technical field
A kind of Chinese medicine that the invention is related to pharmaceutical field, especially Chinese medicine processing is calcined and fried exhaust gas purification system.
Background technique
Being calcined and fried is the common procedure being heat-treated to Chinese herbal medicine, can by the moisture removal in drug, or be allowed to it is modified,
Foaming etc..Being calcined and fried generally is heat source using bituminous coal combustion, therefore generates the pollution of bituminous coal type, and major pollutants are sulfur dioxide.It is existing
It is also fewer in the gas cleaning scheme for being calcined and fried aspect for Chinese medicine, thus it is necessary to propose the application.
Summary of the invention
The invention provides a kind of Chinese medicine and is calcined and fried exhaust gas purification system, including with each machine for stir-frying Chinese medicine and fry medicine pan exhaust outlet
The exhaust pipe of connection, exhaust pipe are connected to flue gas purification system, and the flue gas purification system includes purifying column, connect with purifying column
Purified gas evacuated tube, the blower in purified gas evacuated tube, with the upper pool of purifying column piping connection；In gas cleaning system
Pipeline before system is equipped with interim evacuated tube, is equipped in interim evacuated tube, between interim evacuated tube and flue gas purification system
Air-valve.
Preferably, the pipeline between the upper pool and purifying column is equipped with water valve.
Preferably, the washing water is the NaOH solution of 1.5%-2.5%.
Preferably, the purifying column and sewage plant piping connection, treated sewage is pumped at sewage plant.
Preferably, water pump is equipped between the upper pool and purifying column.
The utility model purification system small investment, operational administrative is easy, and environmental benefit is obvious, imitates to the purification of sulfur dioxide
Rate is high, reaches 97% or more to the purification efficiency of dirt in flue gas.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure, machine for stir-frying Chinese medicine 1 fries medicine pan 2, exhaust pipe 3, interim evacuated tube 4, air-valve 5, purifying column 6, purified gas evacuated tube
7, blower 8, feed liquid pipeline 9, sewage plant 10, upper pool 11.
Specific embodiment
With reference to the accompanying drawing, by the following detailed description, to be more clearly understood that the above and other of the invention
Objects, features and advantages.Hereinafter, the preferred embodiment of the invention will be described in detail with reference to the accompanying drawings.
Such as figure, the utility model is calcined and fried exhaust gas purification system in a kind of Chinese medicine, including with each machine for stir-frying Chinese medicine 1 and stir-fry medicine pan 2
The exhaust pipe 3 of exhaust outlet connection, exhaust pipe 3 are connected to flue gas purification system.
The flue gas purification system includes purifying column 6, connect with purifying column 6 purified gas evacuated tube 7 is set to purified gas
Blower 8 in evacuated tube 7, the upper pool 11 with 6 piping connection of purifying column.After the purified tower 6 of flue gas purifies herein, in air inducing
Machine 8 drains into atmosphere under acting on, and herein, the purifying column 6 is foam absorbing purifying column 6, being capable of SO in purifying smoke2, together
When catharsis is played to flue dust and other medicament volatile ingredients, the hole packing free ratio of the purifying column 6 is 25%, and air velocity is
1.97m/s。
Herein preferably, interim evacuated tube 4 is equipped with before flue gas purification system, in interim evacuated tube 4, interim evacuated tube
Air-valve 5 is equipped between 4 and flue gas purification system；In this way when purification system failure, interim evacuated tube 4 and flue gas purification system
Between air-valve 5 close, the air-valve 5 in interim evacuated tube 4 is opened, and empties the flue gas collected temporarily.
The upper pool 11 is that purifying column 6 conveys washing water by a water pump, and the washing water is 1.5%-2.5%'s
NaOH solution, washing water cleaning principle are as follows: NaOH solution in purifying column 6 with SO2Generate Na2SO3And H2O, Na2SO3And SO2After
Continuous reaction generates NaHSO3, as NaHSO in cleaning solution3When excessively high, cleaning solution is to SO2Absorbability just substantially reduce, at this point,
Cleaning solution in absorption tower should be just expelled to lower pond, meanwhile, NaOH medical fluid should be periodically put into, in upper pool 11 to maintain
The concentration of cleaning solution.
Pipeline between the upper pool 11 and purifying column 6 is equipped with water valve, when water pump conveys cleaning solution to purifying column 6,
Water valve is opened, otherwise is closed.Water is lost as purification system, by connecing the running water pipe regular replenishment in pool side.
The purifying column 6 and 10 piping connection of sewage plant, treated sewage is pumped at sewage plant 10.
Although the preferred embodiment of the invention is disclosed for illustrative purpose, those skilled in the art
Member should be appreciated that under the premise of the scope and spirit created without departing substantially from appended claims present invention disclosed, various
Modification, increase and adulterium are all possible, it is noted that upper under the premise of without departing substantially from the invention scope and spirit
Stating various modifications, increase and altering should all cover within the interest field of the invention.
