Embodiment 1

[0051] This embodiment is a coke quenching process plan for red coke with water spray vaporization and cooling in a closed system. The system is as follows figure 1 shown. The red coke pushed out from the carbonization chamber of the coke oven 1 is loaded into the red coke trough 2, and then moved by the moving vehicle 3 from the horizontal track 4 under the coke oven to the entrance of the inclined track 5 to leave the moving vehicle and connect with the cable of the hoist 6. 7 is connected, rises to the coke quenching tank top track 8 under its drive, and moves to the top of the coke quenching tank 9, and has completed the coke transportation process. Then from the red coke tank, the red coke is passed through the coke charging funnel (not shown in the figure) to the quenching tank (the coke discharge port at the bottom of the quenching tank has been sealed by the coke discharge port cover 19) through the quenching tank red coke inlet 10 ) into coke. After the coke loading...

Embodiment 2

[0059] This embodiment is basically the same as Embodiment 1, except that the coke transportation process is that the red coke trough carrying the red coke pushed out from the coking chamber of the coke oven is moved from the horizontal track under the coke oven to the quenching tank by a moving vehicle After that, the hoist lifts the red coke tank to the top of the quenching tank for coke loading. The process of coke loading is to move the red coke tank directly to the top of the quenching tank to connect with the red coke loading port on the top of the quenching tank, and then open the bottom gate of the red coke tank to directly put red coke into the quenching tank. Water spraying to red coke adopts top water spray pipe 25 to spray water in the tank for 6 seconds and then closes the top water spray pipe, and uses middle water spray pipe 26 and bottom water spray pipe 27 of the same side from one side to spray water from all around , then spray water from the central water s...

Embodiment 3

[0066] This embodiment is basically the same as Embodiment 1, the difference is that the rotary drive mechanism for opening and closing the lid of the coke discharge port is driven by a hydraulic cylinder 37 for opening and closing the lid of the coke discharge port to rotate around the lid of the coke discharge port to drive the support point of the single-rod hydraulic mechanism 57 rotate to open and close the lid of the coke discharge port, such as Figure 10 shown. The locking of the coke discharge port flange and its tank cover flange adopts the turn plate method that can embed the coke discharge port flange and the coke discharge port tank cover flange through reciprocating movement from both radial sides of the coke discharge port flange. Blue locking structure. When the coke discharge port is airtight, the coke discharge port flange locking ring plate 63 is closed from both sides of the coke discharge port flange radially, and the coke discharge port flange and its ta...

Abstract

The invention discloses a quenching apparatus and method of red coke in the coking industry. A quenching tank comprises a quenching tank body with the top provided with a red coke feeding opening and with the bottom provided with a coke discharging opening, a red coke feeding opening tank cover, and a coke discharging opening sealing mechanism; the upper portion of the quenching tank body is provided with a steam discharging opening and a waste gas discharging opening, the steam discharging opening is connected with a steam purifying device, and the waste gas discharging opening is connected with the inlet of a waste gas treatment device or is directly connected to atmosphere; and the wall of the quenching tank body is provided with water spray tubes for spraying water to the tank, the water spray tubes are respectively arranged in a layered manner along the height direction of the quenching tank, the water spray tubes in various layers are individually fed with water or / and different circumferential parts of the same layer are individually fed with water, the radial center position of the quenching tank body is provided with a water spray tube for spraying water to coke in the quenching tank, and the center water spray tube is individually fed with water. The apparatus and the method have the characteristics of less investment, low running cost, short quenching time, heat energy recovery and no pollution.

Description

technical field [0001] The invention relates to a device and method for cooling and energy recovery of red coke in the coking industry, in particular to a device for directly spraying water to vaporize red coke in a closed container to cool the coke, generating steam for recycling and preventing pollutants from being discharged into the atmosphere The invention and the method belong to the fields of energy and energy recovery and utilization and environmental protection. Background technique [0002] Coke is an important raw material for the iron and steel industry. The high-temperature coke (red coke) introduced from the coke oven needs to be cooled rapidly in a short time, that is, coke quenching. Red coke contains a lot of heat energy, if it can be recycled, it can save energy and reduce emissions at the same time. So far, the wet coke quenching method is mainly based on sprinkling water cooling in an open system. This method has simple equipment and fast coke quenching ...
