Description

Technical Field

[0001] The present application relates to the field of dry coke quenching technology, and in particular to a dry coke quenching water-cooling casing protection system. Background Art

[0002] In the CDQ system, the temperature of the primary dust collector is very high and cannot be directly discharged for recovery. It needs to be cooled by a cooling device. The existing CDQ primary dust collector cooling device is a three-layer cylindrical water-cooling jacket at the bottom of the primary dust collector. Circulating cooling water is passed through the inner and outer tubes. The coke powder passes through the cavity between the inner and middle tubes. During the movement of the coke powder, heat is exchanged with the circulating cooling water in the inner and outer tubes, achieving the purpose of cooling the coke powder and recovering heat energy.

[0003] During daily operation, the water-cooling sleeve of CDQ primary dust removal may be damaged by high temperature due to factors such as cooling water interruption, excessive ash discharge, loose sealing and entry of external air causing combustion of coke powder, which greatly reduces the service life of the water-cooling sleeve and increases the operating cost of the equipment. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a CDQ water-cooling jacket protection system to detect the flow and temperature of cooling water to avoid serious accidents such as abnormal cooling water in the water-cooling jacket and over-temperature damage to the water-cooling jacket.

[0005] The present application provides a CDQ water-cooling casing protection system, which adopts the following technical solutions:

[0006] A dry quenching water-cooling sleeve protection system comprises at least two water-cooling sleeve bodies, wherein the lower end side of the water-cooling sleeve body is connected to a water inlet pipe, the upper end of the water-cooling sleeve body is connected to a water outlet pipe, the water outlet pipe is provided with a flow meter and a temperature sensor, and the lower end of the water-cooling sleeve body is provided with an ash discharge pipe.

[0007] Preferably, a control valve is provided on the water inlet pipe.

[0008] Preferably, a temperature monitoring switch is provided at the lower end of the water-cooling jacket body.

[0009] Preferably, the temperature monitoring switch is a KSD302 temperature monitoring switch.

[0010] Preferably, an ash discharge valve is provided on the ash discharge pipe.

[0011] Preferably, an intermediate bin is provided at the lower end of the ash discharge pipe, the intermediate bin is connected to a plurality of the ash discharge pipes, a discharge pipe is provided at the lower end of the intermediate bin, and a discharge valve is provided on the discharge pipe.

[0012] Preferably, a scraper conveyor is provided below the discharge pipe.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The present application sets a flow meter and a temperature sensor on the water outlet pipe. The flow meter is used to measure the flow of cooling water. When problems such as reduced cooling water flow, blockage and interruption occur, they can be discovered and repaired in time. The temperature sensor is used to detect the temperature of the cooling water. When the cooling water temperature rises abnormally, the system prompts that the primary dust removal discharge is abnormal. At this time, the ash discharge valve on the primary dust removal is immediately closed, thereby avoiding serious accidents such as abnormal cooling water of the water-cooling jacket body and over-temperature damage of the water-cooling jacket body, extending the service life of the water-cooling jacket body, and reducing the operating cost of the equipment.
