Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The reactor aims at solving the problem that the reactor is blocked due to the accumulation of a large amount of carbide slag at the bottom of the calcium carbide process reactor in the prior art.
In one or some embodiments of the utility model, an anti-blocking device for an acetylene generator is provided, which comprises an acetylene generator 1, wherein a water feeding pipeline 4 is connected to the bottom of the acetylene generator 1 and is used for feeding water into the acetylene generator 1;
the end part of the water feeding pipe 4 close to the acetylene generator 1 is provided with a stop valve 7.
According to the utility model, the water feeding pipeline 4 is arranged at the bottom of the acetylene generator, and the water feeding pipeline 4 washes the bottom of the acetylene generator 1, so that the acetylene reactor 1 is prevented from being blocked due to accumulation of carbide slag at the bottom of the acetylene reactor 1. As shown in fig. 1, the inventor sets a butterfly valve 6 at the inlet of the water feeding pipeline in the early experimental process,
the butterfly valve 6 is also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve with a closing member (a valve clack or a butterfly plate) which is a disc and rotates around a valve shaft to open and close. Specifically, the butterfly valve opening and closing piece is arranged in the butterfly valve 6, is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, and therefore the opening and closing or adjusting purpose is achieved.
However, the inventor finds that the butterfly valve opening and closing member is a disc-shaped butterfly plate, so the butterfly valve 6 is installed in the water feeding pipeline 4, the disc-shaped butterfly plate exists in the pipeline and blocks the normal flow of water, the cross section of the water feeding pipeline 4 at the butterfly valve 6 is reduced, the water flow resistance is increased, scale is easily formed on the disc-shaped butterfly plate and the valve wall, scale is accumulated at the butterfly valve 6, the water feeding pipeline 4 is blocked after long-term use, the bottom of the acetylene reactor 1 cannot be washed, the bottom of the acetylene reactor 1 is blocked, and the reaction is influenced.
For this reason, the inventor considers to change the butterfly valve for gate valve or stop valve, through contrast and analysis scale deposit to the valve influence to combine actual production experience, think under the same scale deposit speed, the gate valve is compared in the stop valve, changes to take place to close not tight condition, causes the valve closed state sediment thick liquid to reveal and gets into water pipe, causes behind the valve pipeline jam. Therefore, the stop valve is used for replacing the original butterfly valve in the utility model.
As shown in figure 2, the utility model adopts the stop valve 7, and the stop valve 7 is arranged at the position close to the end part of the acetylene generator 1, thereby avoiding the scale from blocking the water feeding pipeline 4.
The stop valve, also called stop valve, is the most widely used valve, and it is popular because the friction between the sealing surfaces is small in the opening and closing process, it is durable, the opening height is not large, it is easy to manufacture, it is convenient to maintain, it is not only suitable for middle and low pressure, but also suitable for high pressure. The closing principle of the stop valve is that the sealing surface of the valve clack is tightly attached to the sealing surface of the valve seat by means of the pressure of the valve rod, and the medium is prevented from flowing. The stop valve is an extremely important cut-off valve, and the sealing of the stop valve is realized by applying torque to a valve rod and applying pressure to a valve clack by the valve rod in the axial direction, so that a sealing surface of the valve clack is tightly attached to a sealing surface of a valve seat, and a medium is prevented from leaking along a gap between the sealing surfaces.
The opening and closing of the stop valve 7 can not lead to the cross section of the water feeding pipeline 4 to be reduced, the water flow resistance can not be increased, the flow speed is reduced, and scale is generated, and the blockage of the water feeding pipeline 4 is avoided.
The utility model improves the pipeline trend at the same time, the original pipeline is in a Z-shaped structure, and the improved pipeline is in an L-shaped structure, so that one elbow is reduced, the water flow resistance is effectively reduced, and the scaling speed of the pipeline is reduced. It will be appreciated that to avoid scale clogging the filler pipe 4, the shut-off valve 7 should be fully open when open.
Because under the normal condition, the generator bottom sediment thick liquid easily gets into the water feeding pipeline, and the scale deposit is gone up to the pipe wall, consequently, stop valve 7 sets up in 4 exits in water feeding pipeline, because the existence of stop valve 7, can effectively prevent pipeline scale deposit behind the valve.

And in the reaction process, the water feeding pipeline 4 is opened to enable the bottom of the acetylene generator 1 to form a vortex for accelerated washing, and after the reaction is finished, the slag discharging pipeline 3 is opened.
Preferably, the top of the acetylene generator 1 is connected with a slurry-slag vapor separator 2. It will be appreciated that a portion of the small particle size carbide slag enters the slurry separator 2 with the water or gas stream.
Preferably, the bottom of the acetylene generator 1 is connected with a slag slurry overflow device 5, and the slag slurry overflow device 5 is higher than the slag discharge pipeline 3. The carbide slag is discharged from the slag discharge pipeline 3 at the lower part, the slag slurry at the upper part enters the slag slurry overflow device 5, and the overflow slag slurry passes through the aqueduct slag slurry stripping tower.
