Coal loading hole cover and seat

The coal loading hole cover and seat can reduce the surface temperature of the coal loading hole cover and the radiation temperature of the coke oven top,reduce the heat loss of the coke oven,and improve the operating environment of the coke oven top,achieving the goal of energy conservation and consumption reduction.

The emission reduction of the carbonization chamber during the coking process mainly depends on the sealing performance of equipment such as furnace doors,coal loading hole covers,seats,and riser covers.The substances leaked from these equipment seals are mainly polycyclic aromatic hydrocarbons(PAH),of which Benzopyrene(BaP)is the most toxic.But during the coking process,the furnace door has a large amount of leakage,and the coal loading hole cover plays an important role in the entire coking process.For production,it is necessary to carefully pour slurry and pressure smoke around the coal loading hole cover.

The invention provides a sealing material that can prevent the discharge of pollutants from the coal charging hole cover and the gaps between the seats during the production process of the coke oven in a coking plant.The sealing material is characterized in that it is mainly composed of silica bath soil powder,especially suitable for the combination of raw silica bath soil powder and cooked silica bath soil powder.It has the advantages of good sealing performance,moderate viscosity,easy detachment when uncovered,and is suitable for mechanized construction.

The coal loading hole cover and seat are furnace protection iron parts,and the installation sequence of furnace protection iron parts

Pave asbestos cloth at the bottom of the furnace head-hoist the protective plate-hoist the furnace column adjustment-install door type clips-adjust the pressure protection plate-install horizontal braces and large and small springs-load the springs-remove door type clips-hoist the furnace door frame to align-temporarily fix and pressurize the braces-fix the furnace door frame-install grinding plates and longitudinal braces.

Installation of flue flap

The flue flap includes the main flue flap and the sub flue flap,both installed on the clay brick arch of the flue.

Throughout the entire process of engineering construction,it is necessary to carefully keep various original records,handle engineering technical data in a serious and timely manner,synchronize the data with the progress,and collect,organize,and archive data in a timely and complete manner.

The appearance quality of the springs used on the coke oven should be smooth and clean,without arsenic spots,cracks,and folded holes.They should be supported perpendicular to the centerline.

After the spring enters the site,mechanical performance tests should be carried out one by one according to the design requirements.Five load compression tests should be conducted first,and there must be no deformation.Conduct an incremental load compression test again,record the test results,and then conduct quality evaluation according to the requirements of the drawings.It should meet the requirements of the drawings before numbering.

The coke oven installation is planned to be organized and constructed in three stages.

1.Stage:The main preparation work for installation includes technical preparation,material planning,processing of machined parts,ordering and procurement of outsourced equipment,incoming inspection and acceptance of equipment,and cooperation with civil engineering work.

2.Stage:The main content of the cold installation stage of the coke oven includes the pre embedding of the bottom spray pipe,the pre embedding of the flue bend,and the installation of the furnace body protective iron to meet the drying conditions.

3.The third stage:installation and debugging stage mainly includes the installation of each repair station,the installation of the four major vehicles and their tracks,the installation of the coke table and coke discharge equipment,the installation,debugging,and closing of the exchange transmission equipment.

Installation process of coke oven equipment

Construction of embedded parts for coke oven

1)The installation of fire holes,coal loading holes,temperature measuring holes,coal loading car track seats,and upper tension sleeves.The overall embedding method for fire holes,coal loading holes,and temperature measuring holes is to wrap loose asbestos ropes and apply a layer of clay cement outside.The equipment installation should meet the size requirements of the drawings,and the surrounding area should be tight.

2)Burial of coal loading truck track seat

Qualified sleepers should be poured in advance according to the drawing requirements,and after the masonry reaches the required height,the sleepers should be accurately placed in the installation position.
