Dry Coke Moisture Uniformity Apparatus

The present invention relates to a device for adding a certain amount of moisture to the dry coke being transported by the conveyor belt, in particular to add a uniform amount of water to the dry coke to produce a high-quality fuel needed in the blast furnace The present invention relates to a device for uniformly adding water to dried coke.

In general, dry coke is a fire extinguishing of the coke produced in the coke plant by dry fire extinguishing method, in order to make the dry coke to the high-quality fuel required by the blast furnace using a suitable amount of water injection to the dry coke being transported. Will add water.

That is, the conventional moisture adding device that can perform the function as described above, as shown schematically in the working state of Figure 1, the upper conveyor belt to be transported in a state where the dry coke is seated on the belt surface 110, the lower conveyor belt 120, which is capable of transporting the dry coke falling from the upper conveyor belt 110 to the blast furnace, and a plurality of sprays in a state installed on the upper conveyor belt 110. The nozzle 131 has a structure consisting of a water spray device 130 to be able to spray the water.

Accordingly, the dry coke seated on the belt surface of the upper conveyor belt 110 is dropped to the belt surface of the lower conveyor belt 120 in a state in which water sprayed through the spray nozzle 131 is absorbed. It is used as a high quality fuel needed in the blast furnace.

However, the water spraying device 130 is installed on the upper side of the upper conveyor belt 110, so that the water is concentrated only on the upper surface of the dry coke being transferred, the overall water addition efficiency is lowered. Therefore, there is a problem that it is impossible to obtain a high quality fuel required by the blast furnace.

In addition, a large amount of water is sprayed to add water corresponding to the amount required in the furnace, but an imbalance in which water is continuously added only to the surface of the coke being transported is not only deepened, but also excessively supplied water. There is another problem that it is not penetrated into the dry coke and partly accumulated on the belt surface to pollute the environment because it drops to the bottom surface of the moisture theory to generate foul water.

Therefore, the present invention was devised to solve the problems described above. After comparing and analyzing the transport amount and the holding temperature of the dry coke, water is sprayed from various angles to add a uniform amount of water as a whole. It is an object of the present invention to provide an apparatus for uniformly adding moisture to dry coke, which is capable of producing a high quality fuel required by a fuel cell.

The present invention for achieving the above object, the upper conveyor belt for transporting the dry coke seated on the belt surface to add water, and the lower portion for transporting the dry coke dropped through the upper conveyor belt to the blast furnace. In the apparatus for adding moisture to a dry coke made of a conveyor belt, a drop is installed in the dropping path of the dry coke, and a plurality of water pipes are installed in the inside of the protector along a horizontal direction. The inlet of the solenoid valve is connected to the size of the opening and closing according to the power supply is installed, the water supply device is provided with a plurality of removable spray nozzles on the inner surface of the water supply pipe to face the dry coke; A detection unit comprising a transfer amount sensor mounted on the lower side of the upper conveyor belt to detect a transfer amount of dry coke, and a temperature detection sensor provided on the upper side of the upper conveyor belt to detect a temperature of dry coke; On the basis of the output signal of the temperature detection unit has a structure consisting of a detection signal processing unit for determining the opening and closing amount of the solenoid valve after comparing and analyzing the transfer time and temperature of the dry coke.

Therefore, by installing the water spraying device having the above-described structure, the appropriate amount of water is added from all directions toward the dry coke falling through the upper conveyor belt is a high quality required in the blast furnace because the moisture is added to the interior of the dry coke. It is possible to obtain the fuel, and to prevent the environmental pollution caused by contaminated water accumulated on the belt surface of the upper conveyor belt.

Here, the protective collection 131 is formed to form a space of a predetermined size to surround the outer path of the dry coke, that is, between the front end of the upper conveyor belt 110 and the upper surface of the lower conveyor belt 120. The protection housing 131 has a structure in which a plurality of polygonal, preferably quadrangular, water supply pipes 132 are formed so as to face in a horizontal direction.

In addition, at the inlet of the water supply pipe 132, one or more solenoid valves 133 are selectively installed to be opened and closed according to the size of the input power, and the direction of dry coke falls on the inner side of the water supply pipe 132. The structure is provided with a plurality of removable spray nozzles 134 which are directed.

Of course, the dry coke dropped through the upper conveyor belt 110 passes through the inner space of the water supply pipe 132 and falls to the belt surface of the lower conveyor belt 120.

In addition, the spray nozzle 134 has a structure in which a plurality of spray nozzles 134 are provided in multiple angles and in multiple stages so as not to be out of the range of dry coke dropped through the spraying range in which water is sprayed.

On the other hand, the upper conveyor belt 110 with a feed amount sensor 140 to measure the transport amount of dry coke on the lower side and a temperature sensor 145 to detect the temperature of the dry coke on the upper side The detection unit 150 made of a structure is mounted.

Hereinafter, with reference to the accompanying drawings illustrating the operation according to the present invention in detail as follows.

First, the feed amount sensor 140 and the temperature sensor temperature 145 installed in the upper conveyor belt 110 detect the amount and temperature of the transfer water, respectively, to generate a current value of a certain size and at the same time When the predetermined signal is transmitted to the detection signal processing unit 160 on the basis of this, the detection signal processing unit 160 modulates the current value according to the change of the generated temperature current value and the feed amount current value, and at the same time, adds or subtracts the current value. It transmits a predetermined signal to the moisture supply device 130 based on the.

At this time, the detection signal processing unit 160 is to organically change the opening and closing of the solenoid valve 133 according to the degree of acceleration or decrease of the current value, it is to determine the amount of spray sprayed according to the transfer amount of the dry coke and the temperature change. .

Meanwhile, referring to FIG. 5 as an example, when the upper conveyor belt 110 is operated and dry coke is simultaneously transferred, the feed amount sensor 140 detects the amount of dry coke and at the same time. After determining whether the set value is set, the temperature is compared with the set temperature value received through the temperature sensor 145.

At this time, if the user's temperature setting value is in the range of 150-180 ° C, the first solenoid valve is opened, and if the temperature setting value is 180-200 ° C, the second solenoid valve is opened, whereby the water injected into the dry coke The amount of addition is controlled.
