Abstract
The invention discloses a dynamic desulfurization internal cooling-type waste gas purification technology. The technology comprises injecting cooling water into high temperature rubber powder in a dynamic desulfurization tank, keeping negative pressure in the dynamic desulfurization tank, fast vaporizing the cooling water so that heat of the high temperature rubber powder is removed, the temperature of the high temperature rubber powder is reduced to 55-65 DEG C from 160-180 DEG C in 20-30min and water vapor is sucked into a cooling tank under negative pressure, and condensing the water vapor by a heat exchanger in the cooling tank.
Description
Technical field
The present invention relates to a kind of dynamic desulfurization inner-cooled waste gas purification technique.
Background technology
In the recovery and reusing and recycling of various scrap rubbers (tire), HTHP desulfurization is committed step therein.When existing production system desulfurization terminates plastic emitting, high temperature rubber powder and material waste gas and steam can only be down to 170 DEG C with regard to direct blowing from 230 DEG C, but high temperature rubber powder and the disperse of a small amount of high-temperature tail gas, there are the risk polluting environment, cause smog disperse in production environment, have a strong impact on the healthy, therefore of production environment and operating personnel, finding a kind of effective solution, can become HTHP dynamic sulfur removal technology the task of top priority of sustainable development.
Content of the invention
The invention provides a kind of dynamic desulfurization inner-cooled waste gas purification technique.
The technical scheme is that
A kind of dynamic desulfurization inner-cooled waste gas purification technique, on the high temperature rubber powder be injected into cooling water in dynamic devulcanizer, keep negative pressure in dynamic devulcanizer, cooling water rapid vaporization is the heat that steam takes away high temperature rubber powder, high temperature rubber powder temperature is reduced to 55 ~ 65 DEG C from 160 ~ 180 DEG C, temperature-fall period is 20 ~ 30min, and steam is sucked in cooling tank by negative pressure, the heat exchanger condensation in cooled tank.
Further, the relative vacuum degree in dynamic devulcanizer is-0.08MPa.
Further, cooling water temperature is 50 ~ 60 DEG C.
Further, condensed steam uses as cooling water circulation.
Compared with prior art, the invention have the benefit that the heat of material waste gas is absorbed by cooling water, by the effect of negative pressure, it is cooled to about 60 DEG C by 170 DEG C at short notice, discharging afterwards has no tail gas loss, use as cooling water circulation after steam is condensed, avoid the pollution to production environment for the high-temperature material waste gas, strengthen the security of operating personnel's working environment, eliminating the hidden danger polluting environment, this technique cools down in digester simultaneously, due to quick cooling, temperature of charge is low, and the tensile strength of reclaimed rubber also increases.
