Description

Smoke-treating equipment for rubber products vulcanizer

The utility model is a kind of environment protection equipment.Be to be used for administering vulcanization of rubber flue gas specially, mainly be applicable to the improvement of rubber sulfuration cylinder flue gas.

Rubber sulfuration cylinder after vulcanization process finishes, is discharged a kind of toxic gas with special stink from cylinder, Here it is vulcanization of rubber flue gas.It pollutes workshop and surrounding environment, is detrimental to health.Therefore suddenly wait to administer, but up to the present domestic also nobody carried out effectively administering to rubber sulfuration cylinder flue gas.

The utility model is for solving the pollution of vulcanization of rubber flue gas.

Because smoke components is very complicated, difficulty of governance is very big.At its various characteristics and material elements, designed a cover integration unit, it is by current limliting, displacement discharge system, and spray, gas-liquid separator and three parts of contact oxidation reactor are formed.

Existing sulfuration cylinder does not have current limliting, displacement apparatus.Existing spray equipment all is single function or bifunctional, can only simply realize one, two kind of function---for example absorb.In addition, existing contact oxidation reactor all is vertical, bulky, and heaviness is highly high, is difficult for installing, and the ability of handling gas is little, only 200 cubic metres of the flows that every cubic metre of volume of reactor per hour can purify.

Characteristics of the present utility model are: open two displacement holes at sulfuration cylinder two end privileged sites, again the sulfuration cylinder go out current limiting regulator of installing on the pipeline from pressure, so just can effectively control from pressure to go out speed and eliminate the flue gas that vulcanizes in the cylinder.Spray, gas-liquid separator are containers with condensation, absorption, absorption, liquid storage and the multiple function of gas-liquid separation.The bottom of container is a liquid storage tank, and first section is the packing layer with absorption property, is eddy flow plate, demist plate and baffling discharge pipe again on it, and container also has outer cooler, and liquid is circulated by water pump.Flue gas has been removed a part of nuisance by container.Contact oxidation reactor is horizontal, is made up of catalyst layer, preheating chamber and three parts of heat exchanger.Catalyst layer is located at top, and preheating chamber is below catalyst layer, and a side is a heat exchanger.This design, compact conformation, highly low, volume is little, installs easily, and the flow that every cubic metre of volume of reactor per hour can purify can reach more than 400 cubic metres.Flue gas is through behind the reactor, and most of noxious material is converted into CO ₂And H ₂O, discharging then.

This abatement equipment is rationally distributed, and floor space is little, and is stable, and regulation effect is good, and through gas Chromatographic Determination, total clearance of noxious material is more than 95% in the flue gas.

The embodiment of this abatement equipment sees accompanying drawing.

Fig. 1 always schemes for abatement equipment, and (1) is equipped with magnetic valve (2) for opening in the displacement hole of sulfuration cylinder (40) two end privileged sites among the figure on it, opens current limiting regulator (3), and flue gas can be by going out from pressure in the cylinder, and its velocity of discharge can be regulated.When going out basic end from pressure, magnetic valve (2) is opened automatically, and blower fan (5) starts, and residue flue gas in the cylinder is discharged.For preventing that flue gas from flowing backwards, be provided with check-valves (4), check-valves in piping (4) also can play safety effect as one-way flow.Two groups of discharge lines are connected in threeway (6).(8) be spray, gas-liquid separator, its detailed structure is referring to Fig. 2.Water pump (7) circulates spray liquid, by imbibition pipeline (25) liquid is sucked from liquid storage tank (15), through outer cooler (37) cooling, sprays through sparge pipe (23) again.(16) be smoke air inlet, flue gas moves upward after entering thus, earlier through packing layer (17), again through eddy flow plate (19), contacts the back with liquid in this stage and continues upwards, discharges by demist plate (21) and baffling discharge pipe (22).(18) are peep-hole among Fig. 2, and (20) are shell, and (24) are hand-hole, and (26) are tapping valve.Flue gas is pumped the continuation motion by blower fan (13) after discharging from baffling discharge pipe (22), and measurement mechanism (12) is used for measuring flue gas flow.Dedusting spark arrester (11) and air control valve (14) have dedusting, reduce concentration and safety effect, and (9) are the electric control boxes of entire equipment.The detailed structure of contact oxidation reactor (10) is referring to Fig. 3.Flue gas enters reactor (10), the heat exchanger (38) of flowing through earlier by blower fan (13) force feed from taking over (28), again by preheater (39), enter first and second reative cell catalyst layer (35) then, finish conversion reaction, at this moment most of noxious material has been converted into CO ₂And H ₂O, temperature rises, and changes heat exchanger (38) over to from passage (34) and (30), and heat output back is discharged by outlet (29).Reactor is provided with heat-insulation layer (27), the thermocouple that thermometric is used (31), and explosion-protection equipment (32), and (33) are shell of reactor, (36) are the preheater case.

Whole manipulations in this controlling device running are pressed predefined procedure auto-control by electric control box (9) except that starting and closing down.
