Description

[Detailed explanation of the invention] [Field of industrial application] The present invention relates to a cyclic city gas generator.
This invention relates to a cyclic city gas generator configured to perform CO adjustment using a CO conversion furnace.

[Conventional technology]

In the case of a cyclic gas generator, one cycle consists of heat, blow purge, make, and make purge, and one cycle consists of approximately 3 cycles in a large-scale equipment.
Minutes and 20 seconds, which is about 5 minutes in a small-scale device, so that gas is produced every said time interval. On the other hand, CO
In the case of a shift furnace, it is more efficient to operate it continuously, so currently one CO shift furnace is set up and operated for two gas generating furnaces. Therefore, between the two generated gas lines connecting two gas generators and one CO converter, we installed a system that allows the lines to be switched and used.
A switching valve is attached to each.

[Problem to be solved]

However, the operating conditions for this switching valve are extremely harsh, as the temperature of the produced gas is 350°C to 400°C, and there is a risk of leakage over time.
If the make gas from one heat mixes with the make gas from the other, there is a danger that the make gas will burn or even explode.

This invention is a produced gas switching valve installed between a gas generation furnace and a CO conversion furnace.
The purpose of the present invention is to provide a cyclic city gas generator with improved safety.

[Means to solve the problem]

The structure and operation of the present invention proposed to achieve the above object are as follows.

In a cyclic city gas generator consisting of two generating furnaces and one CO conversion furnace, the interior is filled with water, the tip of the generated gas line is submerged in the water, and the inlet of the generated gas output line is connected to the water surface. a water valve body that opens into the upper space; a water storage tank that can be filled with water; a drain pipe installed in the water tank, a return pipe installed in the water valve body, and a return pipe installed in the water valve body to return the water stored in the water storage tank into the water valve body. While gas is being sent into the water valve body from the produced gas line, the water in the water valve body is expelled into the water storage tank, and the produced gas line and produced gas outlet line are connected, and CO
An open pump for flowing generated gas to the conversion furnace side,
It is installed in the reflux pipe, and while gas is not being sent into the water valve body from the generated gas line, the water in the water storage tank is refluxed into the water valve body and the tip of the generated gas line is submerged in water. 1. A cyclic city gas generator comprising: a shutoff pump for shutting off a produced gas line and a produced gas output line.

In the above device, the operation of the open pump and the closed pump is synchronized with the cycles of the two gas generating furnaces, and the generation line can be opened and closed automatically.

[Examples and their effects]

The figure shows an embodiment of the present invention, in which 1 is a generated gas line coming out of one gas generator (not shown), 2 is a water valve body, and inside this water valve body 2 is an upper part. It is filled with water to the extent that a space remains, and the tip 3 of the generated gas line 1 is submerged in this water. 4 is from the upper space of the water valve body 2
Product gas output line leading to CO conversion furnace (not shown)
5 is a water storage tank, and the inside of the water valve main body 2 and this water storage tank 5 are communicated through a drain pipe 6 and a reflux pipe 7.

8 is an open pump installed in the drain pipe 6;
Reference numeral 9 denotes a closed pump installed in the reflux pipe 7, and the operation is performed as follows.

While the generated gas is being fed from the generated gas line 1, the open pump 8 drains the water in the water valve body 2 to the water storage tank 5 side via the discharge pipe 6 and communicates with the generated gas output line 4. While the generated gas is not being sent from the generated gas line 1, the shutoff pump 9 circulates water from the water storage tank 5 into the water valve body 2, immersing the tip 3 of the generated gas line 1 in water, and draining the generated gas. The line 4 side is shut off, and the operation of the pumps 8 and 9 is synchronized with the operation cycle of the two gas generating furnaces.

[Effects of this invention]

The structure and operation of this invention are as described above.
Since the generated gas line is opened and closed by the action of water inside the water valve body, it is hardly affected by the high temperature of the generated gas, and thus the generated gas can be shut off reliably and leaks can be prevented over time. There is no need to worry about it occurring. In addition, the water in the water valve body can be removed into the water storage tank via the drain pipe, or the water in the water storage tank can be returned to the water valve body via the return pipe to open or close the generated gas line. Because of this method, the mechanism for opening and closing the generated gas line is simple and reliable.

Therefore, when adjusting CO in the generated gas by combining two gas generators and one CO converter,
Operational safety can be ensured.
