Background technology

Ketene dimer is a kind of advanced acylating agent, is largely used in terms of chemical industry, in pigment, feed, medicine, food additive The industries such as agent are added to have certain application.But there is a segment pipe easily to tie carbon to before cooling down after acetic acid cracking in ketene dimer production, Through our knowhows for many years, just needed to carry out blown converter at 25 days or so except carbon works, otherwise just influence yield and quality, increase Consumption.And driving and parking once need to just increase about 20,000 yuan of electric cost expenditure.Thus extend the blown converter of pyrolysis furnace except the carbon cycle has There is larger economic well-being of workers and staff.

Utility model content

To solve technical problem existing for prior art, the utility model, which provides, a kind of can effectively extend blowing for pyrolysis furnace Stove is except carbon cycle, yield and quality are high, consume less, the ketene dimer pyrolysis furnace carbon removing device that economic well-being of workers and staff is big.

The utility model discloses a kind of ketene dimer pyrolysis furnace carbon removing device, including cracking tube, radiation chamber, refractory brick, Burner on sidewall, Bottom Nozzle Used, convection cell pipe group, quenching boiler, row's cracking gas port, chimney, convection cell, burner corridor, gas phase pipe Road, chuck, coolant intake, cooling water outlet mouth, cooling section；Cracking tube is located at radiation chamber, and radiation outdoor application refractory brick is protected, Side wall is provided with radiation chamber and bottom short flame gas burner heats, Tube surface heat strength is high, is heated evenly；Level is provided with convection cell The array set of heat exchange tubes of placement, to preheating material；Phase pipeline thickening as needed, and additional drop chuck cooling, after coming out of the stove Gas by entering cooling section after gas phase pipeline, can effective extension device facility staff time, because knot carbon is operated in knot carbon device It is interior, gas phase plumbing installation can effective extension device facility staff time, the blown converter of pyrolysis furnace can be made except carbon cycle stretch-out to 45-60 My god, income is obvious.

Radiant section heat output accounts for the 70%-80% of full stove thermic load, is the core of full stove, and cracking reaction is also main Carried out in radiant coil.

Cracking tube uses the single row of tubes of double-side radiation, realizes high temperature, short stop, low hydrocarbon partial pressure cracking, can be to greatest extent Ground receives radiations heat energy.

Chimney is arranged on the top of the convection cell, and to be set using flue gas waste heat, convection section makes full use of convection section Heat has great role to the thermal efficiency for improving stove.

The utility model has the advantages that：The carbon cycle is removed to extend the blown converter of pyrolysis furnace, increase is except carbon dress in Equipment Foundations Put, the blown converter of pyrolysis furnace can be made except the carbon cycle extended to 45-60 days from 25 days or so, income is obvious, and yield is high with quality, consumption It is few, achieve larger economic benefit.

Embodiment

It is further to the utility model below in conjunction with the accompanying drawings in order to be more clearly understood that the technical solution of the utility model Explanation.

As shown in figure 1, the utility model discloses a kind of ketene dimer pyrolysis furnace carbon removing device, including cracking tube 1, radiation It is room 2, refractory brick 3, burner on sidewall 4, Bottom Nozzle Used 5, convection cell pipe group 8, quenching boiler 9, row's cracking gas port 10, chimney 11, right Flow chamber 12, burner corridor 13, gas phase pipeline 6, chuck 7, coolant intake 15, cooling water outlet mouth 14, cooling section 16.

The operation principle of pyrolysis furnace is：It is heated and rises in the cold coal of cracking stock and the advanced people's heating tube in section of convection chamber 8 of dilution steam generation Temperature, it is that cracking reaction occurs in cracking tube 1 subsequently into radiant coil, the cracking gas of generation comes out from boiler tube, leaves stove Chilling at once.Cleavage reaction product immediately enters quenching boiler after leaving pyrolysis furnace, is quenched by water under high pressure with stopped reaction and life 10~12MPa high steam is produced, so as to reclaim heat energy.The gas of fresh baked does not tie carbon, and carbon is tied after coming out of the stove.Fuel is in burner High-temperature fuel gas is generated after burning, first section 2 via radiation, is then emptied again through convection section 8, flue gas from chimney 11.

Cracking tube 1 is located at radiation chamber 2, is protected outside radiation chamber 2 using refractory brick 3, and side wall 4 and bottom are provided with radiation chamber 2 Short flame gas burner 5 heats, and Tube surface heat strength is high, is heated evenly.

Horizontal positioned array set of heat exchange tubes 8 is provided with convection cell 12, to preheating material.

The gas of fresh baked does not tie carbon, and carbon is tied after coming out of the stove, thus 6 thickening as needed of gas phase pipeline after coming out of the stove, and It is additional drop chuck 7 cool, knot carbon be operated in knot carbon device in, so as to the extension device facility staff time, make ketene dimer yield with Quality is high, consumption less, economic well-being of workers and staff it is big.

Cold water enters from the top of gas phase pipeline 6 cooling water inlet 15, under equably being drenched through distribution apparatus, passes through packing layer Afterwards, intermediate water tank is discharged into, cold water is discharged from bottom cooling water outlet mouth 16.

Radiant section heat output accounts for the 70%-80% of full stove thermic load, is the core of full stove, and cracking reaction is also main Carried out in radiant section cracking tube 1.

Cracking tube 1 uses the single row of tubes of double-side radiation, realizes high temperature, short stop, low hydrocarbon partial pressure cracking, can be to greatest extent Ground receives radiations heat energy.

Chimney 11 is arranged on the top of the convection cell 12, and for convection section to be set using flue gas waste heat, convection section is abundant There is great role to the thermal efficiency for improving stove using heat.

Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
