ACETYLENE GENERATOR

The utility model relates to autogenous technology, namely, to acetylene generators for obtaining gaseous acetylene by decomposition of calcium carbide with water, and can be used in gas-flame treatment of metals.

Known designs of acetylene generators containing corne divided by horizontal partitions into a gas generator, in which as a result of the interaction of calcium carbide with water, acetylene is formed, a gas collector that serves to accumulate acetylene, cool and clean it from particles of slaked lime and hydrogen sulfide and ammonia impurities, and a displacer, serving to automatically adjust the amount of acetylene produced, depending on its consumption 1.

A disadvantage of the known acetylene generators is overheating of the upper part of the housing, which reduces the safety of operation.

An acetylene generator is also known, including a corne, the upper and lower transverse partitions placed therein, dividing it respectively into a gas generator, a displacer and a gas collector, and a tube connecting the gas generator and the gas collector, in which the upper partition is installed across the housing, made with an opening provided with a nozzle, moreover, the upper end of the pipe is located above the upper partition, and the lower one forms a gap with the lower partition 2.

The disadvantage of this device is its low reliability and explosiveness.

Closest to the claimed device is an acetylene generator selected as a prototype, comprising a housing, a partition dividing the housing into a blower and a displacer, a horizontal partition dividing the housing into a blower and gas collector, an overflow pipe connecting the gas collector to the blower 3.

The disadvantages of the known acetylene generator are the large size and the presence of hard-to-reach places for washing, as well as the large inertia of the automatic control of acetylene production due to the large surface area of the water in the gasifier, which requires a large amount of acetylene to displace the required volume of water from the gasifier into the displacer, as it is the water surface in the blowing agent and the displacer are equal, and the cross-sectional area of the basket is several times smaller than the cross-sectional area I'm a blowing agent.

To eliminate these drawbacks, an acetylene generator is proposed, comprising a housing with a basket for calcium carbide, a partition dividing the housing into a blower and a displacer, a horizontal partition dividing the housing into a blower and gas collector, a tube connecting the blower to the gas collector, in which, according to a utility model, the partition dividing the housing into a blowing agent and a displacer, made in the form of a shell, hermetically connected to the upper end of the housing with the formation of a gap between its lower end m and the horizontal partition, and the cart is configured to manually move relative to blowing at the working generator.

A comparative analysis of the proposed solution with the prototype and other solutions in the art shows that the set of features set forth in the patent formula is unknown from the existing level of technology and should not be explicitly for a specialist, on the basis of which it is possible to make a view on the compliance of its criteria with the novelty utility model.

The compliance of the proposed solution to the criterion of a utility model, industrial applicability is evident from the following example of a specific implementation of the device.

The utility model is illustrated in the figure, which schematically shows a General view of the acetylene generator.

The acetylene generator consists of a sealed corne 1, two nozzles 2, a cover 3, a basket 4, a partition 5, dividing the corne 1 into a gas blower 6 and a displacer 7, a horizontal partition 8, dividing the housing 1 into a gas blower 6 and a gas collector 9. Gas blower 6 and a gas collector 9 interconnected by a tube 10. The partition 5 is made in the form of a cylindrical shell and coaxially mounted in the housing 1 with a gap between its lower end and the partition 8 and is hermetically connected by the upper end to the housing 1. The basket 4 is made with the possibility of th movement relative gasifier 6 with the generator running, i.e. nr zakrggoy lid 3.

The operation of the acetylene generator is as follows.

Through the mouth of the cornea 1 with the cover 3 removed, the open pipe 2 of the gas collector 9 and the closed pipe 2 of the displacer 7 pour water. Water fills the gasifier 6, reaches the upper end of the tube 10 and does not flow along it into the gas collector 9. As soon as excess water begins to flow from the nozzle 2 of the gas collector 9, the generator is stopped filling with water and the nozzle 2 is hermetically sealed with a stopper.

A basket 4 filled with calcium carbide is installed inside the housing 1, which is sealed with a screw 3. In this case, the basket 4 is in its highest position at the water level in the blowing agent 6.

Thus, during sealing of the housing 1 with a lid 3, calcium carbide does not come into contact with water. This ensures the safe operation of the generator and eliminates the leakage of acetylene into the atmosphere.

Then the basket 4 is manually pulled to its lowest position. The lower part of the basket 4 with calcium carbide is immersed in water, a chemical reaction begins, accompanied by the release of acetylene. Acetylene from blowing agent 6 through

tube 10 enters g 1 collector 9, passing through a layer of water. From the gas collector 9, purified and cooled acetylene is supplied to the consumer.

With a decrease or complete cessation of the selection of acetylene from the generator, its pressure in the blowing agent 6 increases. This leads to the movement of part of the water from the blowing agent 6 to the displacer 7. The water level in the blowing agent 6 is lowered. The volume of calcium carbide in contact with water decreases, or the contact ceases altogether.

The release of acetylene in this case decreases or completely stops.

With an increase or resumption of selection of acetylene, its pressure in the blowing agent 6 decreases. Water from the displacer 7 flows back into the blowing agent 6. The acetylene increases or resumes.

Thus, the amount of acetylene formed in the generator is automatically controlled depending on its flow rate.

Since the surface area of the water of the blowing agent 6 is less than the surface area of the water of the displacer 7, to drain the basket 4 it is required to displace a relatively small (compared to the prototype) volume of water.

Due to this, the inertia of regulation of acetylene incorporation decreases and the efficiency increases generator.

If it is necessary to stop the operation of the generator, the basket 4 is lifted manually to its highest position.

To resume operation of the generator, the basket 4 is lowered manually to its lowest position.

After the complete production of calcium carbide, the lid 3 is removed along with the basket 4, the tube plugs 2 are opened, the water and the formed lime sludge are drained.

parts of the body. The generator is convenient and safe to operate, compact, has less weight and inertia for automatic control of acetylene production. The use of the proposed design improves the reliability and efficiency generator.
