Abstract
After the optimum cure of tyre is completed, the inert gas nitrogen gas-steam mixed gas in the rubber bag of vulcanizing machine can be discharged, through the processes of dilatation and decompression, and discharged into steam-water separation tank, through the processes of temperature drop and cooling by carburetor and drainage, recovered in gas storage bag or gas storage box, then the gas is pressurized by compressor and fed into medium-pressure storage tank, can be provided for vulcanizing machine for reuse. Said invention possesses the advantages of high nitrogen gas recovery rate, simple technological process and quick recovering speed.
Description
The present invention relates to a kind of chemical process, particularly a kind of inert gas of tire inert gas sulfuration reclaims technology.
The sulfuration of tire inert gas is a kind of novel vulcanization process.Adopting pressure during vulcanized tyre is that 1.4～1.7Mpa, temperature are that 190～210 ℃ saturated vapor charges into glue and assists the tire heating, feeds inert gas again, vapor mixing and boost to 2.1～2.8Mpa to tire pressurization in assisting with glue.This curing system has the advantage of water curing system and steam vulcanization (cure) system simultaneously, and has overcome the shortcoming of these two kinds of curing systems, is a kind of novel sulfuration process that occurs in recent years.But in these tire plant, the inert gas that great majority all directly will vulcanize after finishing drains into atmosphere, it is not carried out recycling.Inert gas after introducing Japanese a company once sulfuration finishes to the tire inert gas according to the 99th page to 102 pages of " tire industry " magazine 1996 the 2nd phases had carried out recycling.The inert gas that the said firm adopts is a nitrogen.The technological process of the inert gas recovery section of its sulfuration process is: (1) is when tire optimum cure end, when preparing depanning, close the nitrogen transfer valve, stop in glue is assisted, to charge into nitrogen, open transfer valve simultaneously, the high pressure nitrogen that the 1st tyre vulcanizer (group) is discharged is recovered in the steam-water separator.This step is called high pressure and reclaims.(2) after high pressure reclaims and finishes, close the nitrogen transfer valve immediately, stop the high pressure nitrogen that vulcanizer (group) is discharged is recovered in the steam-water separator.Open the nitrogen transfer valve then, will be recovered in the low pressure storage tank by the low-pressure nitrogen that the 1st tyre vulcanizer (group) is discharged.This step is called low pressure and reclaims.(3) after feeding cooling,, open the nitrogen transfer valve once more and the low-pressure nitrogen of the 1st tyre vulcanizer (group) is recovered in the low-pressure nitrogen storage tank.This step is called residual air and reclaims.This shows, its complex process, rate of recovery of nitrogen is low, and the process unit investment is big, and recovery speed is slow, and heat absorption and heat radiation relation be balance well, the production cost height.
The inert gas that the purpose of this invention is to provide a kind of tire inert gas sulfuration reclaims technology, and this new technology can further improve rate of recovery of nitrogen, and efficent use of resources reduces the tire manufacturing cost.
The object of the present invention is achieved like this:
Technological process of the present invention is:
After A, tire optimum cure finished, the high temperature inert gas nitrogen one vapor mixing gas in the tyre vulcanizer capsule was discharged from vulcanizer, drains into after dilatation, step-down in the carbonated drink knockout drum;
B, mist are recycled in gas-storing bag or the gas storage holder through vaporizer cooling, cooling and hydrophobic again;
C, compressor boost to 2.1～2.8Mpa with the gas that is recovered to, and press in the storage tank in sending into, and supply with vulcanizer again and use.
Inert gas of the present invention is a nitrogen.
Operation principle of the present invention is as follows: (A) when tire optimum cure end, when preparing depanning, inert gas reclaims that valve is corresponding to be opened, and the nitrogen of the inert gas in the tyre vulcanizer capsule-vapor mixing gas is recycled to (or being recycled in the carbonated drink knockout drum) in the carbonated drink knockout drum again after the cooling of exhaust air inlet heat exchanger.(B) when nitrogen-vapor mixing gas passes through the carbonated drink knockout drum, before entering the carbonated drink knockout drum, respectively be connected with a water seal on the tank body of carbonated drink knockout drum.Condensed water is discharged by water seal, and the gases at high pressure that also recovery obtained carry out the dilatation step-down simultaneously.(C) behind the nitrogen vapor mixing gas process carbonated drink knockout drum, obtain the low-pressure nitrogen of higher temperature, after it carries out heat exchange by vaporizer and with its outer wall, promptly be recovered in a gas-storing bag or the dish gas holder.(D) compressor is forced into 2.1～2.8Mpa again again with the nitrogen of retrieving in gas-storing bag or the gas storage holder, and presses in the storage tank in delivering to.(E) be recovered to the middle interior nitrogen of storage tank of pressing with from liquid nitrogen pump is delivered to, pressing the nitrogen in the storage tank to supply with the vulcanizer use again.
Respectively be connected with a water seal on the tank body of carbonated drink knockout drum of the present invention, it mainly has been safety valve and hydrophobic effect, when exhaust air inlet heat exchanger heated up liquid nitrogen gasification, recovering medium can cool hydrophobic well, preferably balance the relation of heat absorption with heat radiation.
The present invention has the following advantages: 1, rate of recovery of nitrogen height
Because the present invention adopted airbag (or gas holder) and water seal arrangement on the tank body of carbonated drink knockout drum, make to be recovered at last that nitrogen gas pressure is about 1 atmospheric pressure in gas-storing bag or the gas storage holder, the rate of recovery is up to 96%.And in the nitrogen recycling technology that is adopted in the world at present its rate of recovery the highest only be 50%.2, technological process and device are simple
Owing to used water seal arrangement and gas-storing bag elements such as (or dish gas holders) dexterously, make that technological process and device are extremely simple in the technological process of the present invention, it is also very easy to operate.3, recovery speed is fast
Because during discharging, pressure reduction is big, flow is big, reclaims rapidly, so recovery speed is fast, can save time, and improves vulcanizer production capacity.4, preferably balance the heat absorption with the heat radiation relation
The present invention preferably balance the relation of heat absorption and heat radiation in the technological process, liquid nitrogen was vaporized easily, the cloakroom nitrogen of retrieving is cooled off easily, be beneficial in gas-storing bag gas storage and satisfy the low requirement of compressor inlet air temperatures.
