Drench the top of scrubbing tower.
Preferably, exhaust treatment system also includes the active carbon adsorber connected with the gas outlet of centrifugal blower, remaining portion
After point waste gas adsorbs again in absorbent charcoal adsorber, clean gas Jing exhaust chimney enters air, such design be in order to
By the more thorough of waste gas purification.
Preferably, exhaust treatment system also includes the exhaust chimney connected with active carbon adsorber, through purified treatment
Gas, finally enters air by exhaust chimney.
Preferably, spray scrubber is made using the material of acid-alkali-corrosive-resisting.Spray washing process is former using acid-base neutralization
Reason, i.e., processed alkaline waste gas using dilute sulfuric acid spray liquid.Spray mode takes circulated sprinkling, and in due course and
When supplement spray liquid.
Preferably, heater includes the inner coil pipe being arranged on inside kettle and the chuck being arranged on outside kettle, inner disc
Pipe and chuck are equipped with the passage of external circulating heat conduction oil.Such design, can be using circulating heat conduction oil from chuck and inner disc
Two positions of pipe are heated to the reaction mass in kettle, are heated compared with single chuck, and the efficiency of heating surface is higher；Also, due to
Using inner coil pipe, contact with the solid material in kettle more fully, the uneven and band because solid material is heated can be obviously improved
The product quality problem for coming.
Due to the utilization of above-mentioned technical proposal, this utility model has compared with prior art following advantages：
The process units of this utility model polyamide polyamines, condensation collection system removes unwanted moisture from kettle,
The quality of product is improved, exhaust treatment system will be discharged after produced waste gas purification, and can be made in process of production anti-
Answer kettle to be reacted under negative pressure state, be conducive to plus fast response.The device can lift the product of polyamide polyamines intermediate
Quality, improve production efficiency, reduce the waste gas discharge of system, meet the trend of current energy-saving and emission-reduction.
