Description

Acetylene generator

The present invention is a kind of device that is used for producing acetylene.

The carbide-feed generator that extensively adopts in China mainly contains two kinds at present, and a kind of is small-sized carbide-feed generator (0.5-10m ³/ H), another kind is a heavy-duty acetylene generator.For example: the type medium pressure acetylene generator Q4-5(or 10 that welding machine factory in Shanghai produces); the YJPH0.8-6(10 that Jiangsu Jingjiang protection instrument factory is produced) type medium pressure acetylene generator; the design of Shanghai the 9th designing institute, the gas production rate that factory produced as Hebei province made the Qinhuangdao is 40m ³The low-pressure acetylene generator of/H.These devices have a common ground, all can not reconcile pressure and gas production rate automatically according to the needs of gas consumption.Can only drop into a small amount of calcium carbide, aerogenesis finishes at every turn, in the time of need dropping into calcium carbide again, must shut down the back deslagging and change water.Can not change water at the situation lower dreg discharging that does not influence aerogenesis, the adjustment of gas production rate and pressure mainly is by manual operation, therefore when gas consumption reduces or stops using, as untimely craft calcium carbide indigo plant is mentioned, will cause a large amount of acetylene gas to enter atmosphere, cause waste, owing to be hand control, the fluctuation of producer operating pressure is big.Owing to the requirement of aerogenesis speed and pressure, these devices all need be by the certain specification fragmentation when reinforced again.During small-sized in addition carbide-feed generator deslagging, all be directly to come indoorly, environment is damaged, because residue contains entrap bubble, indoor acetylene gas content is increased simultaneously, reduced safety coefficient.

Problem in view of above-mentioned prior art exists the objective of the invention is to design a kind of carbide-feed generator by elevated tank automatic pressure control and gas production rate.This device can once drop into does not need broken calcium carbide in a large number.Can change water at the situation lower dreg discharging that does not influence work, and can regulate gas production rate and pressure automatically with the variation of extraneous gas consumption.And this device radiation performance is good, pulp water is discharged to outdoor, has improved environment, has improved safety coefficient.

Principal feature of the present invention is to use the elevated tank that is communicated with main jar, controls gas production rate and pressure automatically.Because the employing of elevated tank, make that this device can be with vertical concentrated charging method, and with one against pulp water being discharged to outdoor towards the formula slag discharging device.

Below in conjunction with accompanying drawing more detailed explanation is done in invention:

" carbide-feed generator " of the present invention installs as shown in Figure 1, and (11) are elevated tanks, and it is by dividing plate (8), upper water box (9), and exhaust radiating pipe (10), upflow tube (2) is formed.Be communicated with main jar (1) by water pipe (4).In original state, all gate valves are closed, after the calcium carbide indigo plant (5) of packing into, shut feeding mouth (12), open clear water gate valve (9), be communicated with gate valve (3) and water level valve (19), when water level valve (19) has water to overflow, shut-off valve (3) and valve (19) and purge valve (9).At this moment, as long as open communicating valve (3), water just flows in the master jar (1) automatically, and main jar (1) interior liquid level rises, with the contact surface increase of calcium carbide, the acetylene gas that produces increases, pressure increases, and because of the effect of acetylene gas pressure, and has stoped the rising of liquid level, when reaching required force value, open gate valve (15) beginning air feed.When if the outside gas consumption increases, main jar (1) interior gas reduces, and pressure descends, liquid level then rises automatically, and to increase gas production rate, master's jar (1) internal pressure increases when extraneous gas consumption reduces, stop liquid level to rise again, when the outside stops to use gas, along with increasing of main jar (1) interior gaseous tension.Liquid level continues to descend, when pressure reaches P, and (P=(hi+ △ hi-h) ((1 kilograms per centimeter ²10 meters of)/()), wherein hi is the height (unit: rice) of water tank (11); △ hi is the variable quantity (unit: rice) of main jar (1) interior elevation of water surface; H is the elemental height (unit: rice)) of main jar (1) interior liquid level, water is extruded in the elevated tank (11), water is separated fully with calcium carbide, and stop aerogenesis automatically, acetylene is maintained in P～P+ △ P scope, be in dynamic equilibrium state.Wherein: P is 0.2～1.2kgf/Cm ²In arbitrary definite value, △ P=0.02～0.05kgf/Cm ², elevated tank be arranged so that pressure-stabilisation, and can regulate gas production rate and pressure automatically with the variation of extraneous gas consumption.Owing on elevated tank, be provided with exhaust radiating pipe (10), make the liquid in main jar (1) obtain good cooling by the water in water pipe (4), the elevated tank.

The present invention can change the characteristic of water at any time according to elevated tank (11), adopted vertical concentrated charging method, calcium carbide is packed in the calcium carbide indigo plant (5), the feasibility of this feeding mode is because of when work, have only calcium carbide indigo plant (5) bottom △ hi to contact with water, and the contact height of liquid level and calcium carbide can not surpass the maximum value of △ hi, this is according to elevated tank (11) and gas production rate design, the maximum volume that can design elevated tank (11) equates (or the volume that makes elevated tank (11) is slightly larger than the variable quantity of main jar (1) interior water) with the volume change of main jar (1) interior water, after calcium carbide indigo plant (5) bottom calcium carbide is by water dissolution, under action of gravity, the calcium carbide on the blue top of calcium carbide will fall to replenishing to finish the task of continuous aerogenesis automatically, and the employing of this mode makes can drop into does not at every turn need broken calcium carbide in a large number.

For directly being discharged to carbide slag outdoor, it is one contrary towards the formula slag discharging device that the present invention has designed, and it is by a curved pipe (23), valve (20), valve (21), form with contrary wash pipe (22), curved pipe (23) is communicated with main jar of (1) bottom and directly derives outdoor.This setting and water-stop sheet (8) have been formed deslagging and have been changed the water device.It has solved in the prior art problem that can not change water at the situation lower dreg discharging that do not influence work.When gas temperature in main jar (1) is higher than regulation numerical value or arbitrary moment, the need deslagging changed water, cooling, open gate valve (9).Clear water flows into elevated tank (11), at this moment owing to hydraulic pressure identical the be in relative balance state of the air pressure in main jar (1) with elevated tank (11).Overflowing water-stop sheet (8) so clear water can not enter in main jar (1) is flowed out by upflow tube (2).At this moment open scum gate valves (20) because the discharge of pulp water descends the liquid level in main jar (1), cause main jar (1) interior acetylene gas pressure to descend, the water in the elevated tank (11) charges in main jar (1) to keep works better automatically by the output of pulp water simultaneously.Behind the closing gate valve (20), main jar of (1) internal pressure is very fast to reach balance with elevated tank (11) hydraulic pressure, and the water that gate valve (9) is supplied with can not enter in main jar (1) and overflow.Pulp water directly is discharged to outdoor, and environment is improved, and has improved safety coefficient.
