Abstract

The utility model discloses a modified dry coke quenching water-cooling jacket structure, including installing the dust remover on the platform steel construction, a dust remover lower extreme is setting gradually blind plate and water jacket by last under to, and the water jacket divide into outer water jacket and interior water jacket, and interior water jacket middle part is setting up the baffle and is being divided into the two parts of symmetry with interior water jacket middle part, and the interior water jacket top is sealed and apart from the blind plate interval be 200mm, is setting up interior water jacket inlet tube and interior water jacket outlet pipe on the baffle both sides water jacket wall of interior water jacket respectively, and interior water jacket inlet tube and interior water jacket outlet pipe are all worn out from outer water jacket wall upper level. The structure can play a role in water cooling, and can not generate the water leakage condition, thereby ensuring the stable operation of the coke dry quenching system.

Description

Improved dry quenching water-cooling sleeve structure

Technical Field

The utility model relates to a modified dry quenching water-cooling jacket structure.

Background

The coke dry quenching device is provided with 2 groups of 4 water-cooling sleeves at the lower part of a primary dust remover, and mainly has the function of cooling high-temperature coke powder (about 900 ℃) collected by the primary dust remover (below 300 ℃) and then entering an ash storage hopper through a grid valve. The two ends of the water-cooling sleeve are provided with a blind pipe for plugging, the middle of the water-cooling sleeve is provided with a partition plate, industrial production water enters from an inlet and then is discharged from an outlet, and the heat exchange cooling is carried out on the coke powder. The top of the inner sleeve is sealed by refractory mortar to insulate heat and prevent the direct scouring of hot coke powder to wear the inner sleeve pipe. During the use process, the ash discharge of the No. 2 water-cooling sleeve is not smooth, the discharged wet coke powder is discharged, the offline inspection finds that the inner sleeve leaks water due to cracks, the water leaked from the inner sleeve enters the hot coke powder to enable the coke powder to be bonded and not to slide, and finally the device cannot run. After water leaks, the water is vaporized when encountering red coke powder, and because the primary dust remover is a negative pressure area, the content of H2 in circulating gas in a system is increased after water vapor enters a circulating system, the temperature of a boiler inlet is increased, and certain harm is formed to the safe and stable operation of a dry quenching system.

Disclosure of Invention

An object of the utility model is to provide a modified dry coke quenching water-cooling jacket structure can play the water-cooling effect, can not produce the condition of leaking again, ensures the steady operation of dry coke quenching system.

The utility model aims at realizing like this, a modified dry quenching water-cooling jacket structure, including installing the dust remover on the platform steel construction, a dust remover lower extreme is setting gradually blind plate and water jacket under to by last, and the water jacket divide into outer water jacket and interior water jacket, and interior water jacket middle part is setting up the baffle and is dividing into the two parts of symmetry with interior water jacket middle part, and interior water jacket top is sealed and apart from the blind plate interval be 200mm, is setting up interior water jacket inlet tube and interior water jacket outlet pipe on the baffle both sides water jacket wall of interior water jacket respectively, and interior water jacket inlet tube and interior water jacket outlet pipe are all worn out from outer water jacket wall upper level.

The utility model discloses simple structure, interior water jacket top seal and distance the blind plate interval be 200mm, can play the water-cooling effect, can not produce the water jacket condition of leaking again, ensure dry coke quenching system's steady operation.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic view of the structure of the present invention.

Detailed Description

An improved coke dry quenching water-cooling jacket tube structure is shown in figure 1 and comprises a primary dust remover 1 arranged on a platform steel structure 2, wherein a blind plate 3 and a water jacket are sequentially arranged at the lower end of the primary dust remover 1 from top to bottom, the water jacket is divided into an outer water jacket 4 and an inner water jacket, a partition plate 8 is arranged in the middle of the inner water jacket to divide the middle of the inner water jacket into two symmetrical parts, the top end 7 of the inner water jacket is sealed and has a distance of 200mm from the blind plate 3, an inner water jacket water inlet tube 5 and an inner water jacket water outlet tube 6 are respectively arranged on inner water jacket walls on two sides of the partition plate 8 of the inner water jacket, and the inner water jacket water inlet tube 5 and the inner water jacket water.
