Abstract

The invention discloses a technology and equipment for recovering and purifying gas emitted from a devulcanizer in the production process of rubber regeneration. High-temperature gases emitted from the devulcanizer is treated by heat recovery, circulated cooling and washing with condensing liquid, terminal treatment (active carbon adsorption or combustion-supporting incineration) and condensationrecycling, thereby realizing standard waste gas emission and zero wastewater discharge. The technology and the equipment have the advantages of environmental protection, energy saving, quick gas emission, no block, low gas emission resistance, thorough gas emission, less atmospheric gas emission of a devulcanizer port, separation-recovery-separation process of rubber power and organic matters, less investment, less occupied area and the like.

Description

Exhaust gas of devulcanizer used in rubber regeneration by washing separation method purification treatment technology and equipment

One. technical field

The present invention relates in regenerated rubber (reclaimed rubber) production process, recovery, the purifying treatment of digester institute emission gases reach the purpose of energy-conserving and environment-protective.Belong to field of environment protection.

Two. technical background

The rubber regeneration method of desulfurization in the vulcanizer.After reaction finishes, emit a jar interior gas, for containing multiple organic high-temperature water vapor, wherein have on a small quantity with what various auxiliary agents (coal tar, Stockholm tar, activator etc.) entered that jar internal reaction generates and be phenyl ring and heterogeneous ring compounds such as the benzene,toluene,xylene of solid or liquid, naphthalene at normal temperatures, and the hydrogen sulfide of few part, the taste people that chokes, wastes energy at the serious harm environment.

Treatment process amount commonly used at present: with the mode of high-temperature body by direct condensation in shell and tube heat exchanger condensation or the feeding pond.Exist that the steam discharge resistance is big, steam discharge is incomplete; Condensation is not thorough, system is easily stopped up; The indissociable shortcoming of organism.

Task of the present invention is to develop low resistance, does not have the exhaust treatment system one exhaust gas of devulcanizer used in rubber regeneration by washing separation method purification treatment technology and the equipment of pressing full condensation, phlegma to recycle.Realize up to standard, the wastewater zero discharge of exhaust gas emission.

Three. summary of the invention

A. technology contents

Task of the present invention is finished in the following manner:

By accompanying drawing () as can be known, the present invention is separated by rubber powder separation, heat recuperation, condensation washing, and main process such as terminal process is formed.

The high-temperature steam that digester is discharged at first enters rubber powder separator (1), isolates the foreign material such as rubber powder carried secretly in the gas, avoids blocking pipe; Isolate the high temperature gas behind the rubber powder, enter heat recoverer (2) material that domestic water, boiler feed water or coal tar wet goods need heat is heated, reclaim heat; Enter condensation washing knockout tower (5) again, in this tower, contact with end temperature circulating condensing liquid under the spray, heat exchange, washing, high-temperature steam is got off by total condensation, most of organism of discharging with the high temperature gas also is condensed simultaneously, enter in the disengagement chamber of this equipment bottom, isolate greasy dirt impurity such as (organism).High temperature phlegma after temperature raises enters by recycle pump (10) and recycles after primary cooler (6) and time water cooler (7) and water coolant heat-shift reduce temperature.Unnecessary water of condensation enters water of condensation manifold (4) by upflow tube, sends digester back to by condensate pump (9) then and reuses.

The used water coolant of primary cooler (6) recycles after (11) through cooling tower (8), cooling water circulating pump; Inferior water cooler (7) feeds phreatic water or chilled brine when summer high temperature, circulating condensing liquid is carried out further cooling of degree of depth cooling, improves the system handles effect.

A small amount of incondensable gas enters terminal process device (3), the situation different according to the user, take charcoal absorption/combustion-supporting burning mode finally to handle, remove the gas that hydrogen sulfide, organism etc. are poisonous, be harmful to, have the people's taste of choking, discharge after meeting the environment protection emission requirement.

B. major equipment

Condensation washing knockout tower is the key equipment of present technique.By accompanying drawing (two) as can be known: this equipment is two cylindrical section shape tower type containers, and epimere is the condensation washing section, and hypomere is for storing segregation section.There is dividing plate upper and lower section centre, has riser to communicate on the dividing plate, guarantees upper and lower section pressure equilibrium.

Contain organic high-temperature water vapor and enter top condensation washing section from steam inlet (1), contact with the cryogenic condensation liquid of each nozzle of top (6) spray and to carry out heat exchange, water vapor and organism wherein are condensed, and flow into the bottom by downtake (8) and store segregation section.At this, the organism that proportion is lighter floats to top, can discharge from oil discharge outlet (9), and heavy sinking at the bottom of the tower regularly cleared up away from inspection port (10); Unnecessary water of condensation flows out from overflow port (2) to be reused.A small amount of incondensable gas is discharged from steam drain (5).

One section porcelain ring filler (4) is equipped with on condensation washing section top, and during summer high temperature, this packing section upper nozzle ejection is through time water cooler degree of depth refrigerative circulating condensing liquid.Gas is further cooled off washing, improve treatment effect.

Nozzle (6) is spiral spiral case nozzle, is evenly distributed, atomizing effect is good, be difficult for to stop up.

Store segregation section and be provided with safety tube (7), when the equipment internal pressure was too high, water from then on pipe overflowed.
