Description
Technical field
The present invention relates to a kind of device of field of papermaking, what be specifically related to is a kind of modifying device of drying cylinder.
Background technology
In paper industry, paper pulp leaves more moisture after becoming into paper, paper surface also out-of-flatness is bright and clean, need to be filled with steam the heat that drying cylinder provides a large amount of, the moisture in paper is dried by the outer wall of drying cylinder, and Xuan machine-glazed paper face, but current drying cylinder is in use caught a cold due to steam and is condensed into water, how drying cylinder inwall forms water ring, be unfavorable for the normal rotation of drying cylinder, affect stability and the drying efficiency of equipment, and provide the steam pipework of steam easily to produce noise at links to drying cylinder, do not obtain recycling fully being unfavorable for energy-conserving and environment-protective finally by the aqueous water be fully condensed into.
Summary of the invention
The technical issues that need to address of the present invention are, provide a kind of and effectively can improve drying cylinder operating efficiency, reduce noise in drying cylinder use procedure and the modifying device of energy-conserving and environment-protective.
Technical scheme of the present invention is: a kind of modifying device of drying cylinder, comprise steam turbine, steam pipework, drying cylinder, be connected by steam pipework between steam turbine with drying cylinder, hydrophobic development unit muffler and vapour booster pump is provided with between the steam drain of described steam turbine and the intake valve of drying cylinder, steam after the process of hydrophobic development unit muffler enters in vapour booster pump and pressurizes, Sewage treatment circulating device is provided with between the air outlet valve of drying cylinder and the water inlet of steam turbine, steam releasing silencer is provided with between the air outlet valve of drying cylinder and Sewage treatment circulating device, steam is condensed into aqueous water through steam releasing silencer and is back in steam turbine through Sewage treatment circulating device.
As preferably, described vapour booster pump, hydrophobic development unit muffler and fixed connection place, ground are provided with elastic caoutchouc shock insulation seat, and described steam pipework shock bracket is installed fixing.
As preferably, described steam pipework is equipped with safety valve, and safety valve is provided with muffler.
As preferably, described steam pipework is enclosed with butyl rubber, and butyl rubber is wrapped with asbestos ring, has stainless steel protective cover at asbestos ring overcoat.
After adopting technique scheme, tool of the present invention has the following advantages:
Effectively can improve set up vapour booster pump between drying cylinder and hydrophobic development unit muffler after and enter steam flow in drying cylinder and pressure, the steam of high pressure can form strong flow-disturbing in drying cylinder again, easily significantly reduce the formation of water ring, add the efficiency that drying cylinder uses steam heat, moisture in paper can be removed fast, paper obtains better flatness, after setting up hydrophobic development unit muffler between steam pipework, effectively decrease the generation of noise, steam pipework wraps up the generation that butyl rubber decreases noise on the one hand, and decrease heat and run off by heat radiation, more energy-conservation, using shock bracket to install fixed steam pipeline is also produce unnecessary noise to prevent from resonating, after adopting such noise-reducing structure, noise on papermaking streamline can control in harmless scope, before turbine water induction mouth, arrange Sewage treatment circulating device makes waste water be reused, energy-conserving and environment-protective.
Accompanying drawing explanation
Accompanying drawing 1 is the layout schematic diagram of the modifying device of drying cylinder of the present invention;
Accompanying drawing 2 is the sectional view of the steam pipework of the modifying device of drying cylinder of the present invention.
Shown in figure, 1, steam turbine, 10, water inlet, 11, steam drain, 2, steam pipework, 20, safety valve, 21, muffler, 22, shock bracket, 23, butyl rubber, 24 asbestos rings, 25, stainless steel protective cover, 3, drying cylinder, 30, intake valve, 31, air outlet valve, 4, vapour booster pump, 5, hydrophobic development unit muffler, 6, steam releasing silencer, 7, elastic caoutchouc shock insulation seat, 8, Sewage treatment circulating device.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As Fig. 1, shown in Fig. 2, the drying cylinder noise-reducing structure of the present embodiment comprises steam turbine 1, steam pipework 2, drying cylinder 3, be connected by steam pipework 2 between steam turbine 1 with drying cylinder 3, hydrophobic development unit muffler 5 and vapour booster pump 4 is provided with between the steam drain 11 of described steam turbine 1 and the intake valve 30 of drying cylinder 3, steam after hydrophobic development unit muffler 5 processes enters in vapour booster pump 4 again and pressurizes, Sewage treatment circulating device 8 is provided with between the air outlet valve 31 of drying cylinder 3 and the water inlet 10 of steam turbine 1, steam releasing silencer 6 is provided with between the air outlet valve 31 of drying cylinder 3 and Sewage treatment circulating device 8, steam is condensed into aqueous water through steam releasing silencer 6 and is back in steam turbine 1 through Sewage treatment circulating device 8.Steam pipework 2 is installed on ground by shock bracket 22 or other are in order on fixing supporter, steam pipework 2 is enclosed with butyl rubber 23, butyl rubber 23 is wrapped with asbestos ring 24, asbestos ring 24 is wrapped with stainless steel protective cover 25, because butyl rubber 23, asbestos ring 24 possess good in heat-resistant quality of making an uproar, steam-energy keeps the condition of high temperature, and stainless steel protective cover 25 is to prevent external environment condition to the corrosion of steam pipework 2.Steam pipework 2 before hydrophobic development unit muffler 5 is provided with safety valve 20, and safety valve 20 is used for controlling steam flow and pressure alarm, safety valve 20 is provided with muffler 21 to reduce herein due to the noise of air-flow convolution generation.Steam pipework 2 is then connected with a hydrophobic development unit muffler 5, and hydrophobic development unit muffler 5 and fixed connection place, ground are provided with elastic caoutchouc shock insulation seat 7, and to prevent because the air-flow in hydrophobic development unit muffler 5 is unstable, generation is vibrated.Enter in vapour booster pump 4 via the steam after hydrophobic development unit muffler 5 processes with steam pipework 2, high steam after pressurization enters in drying cylinder 3 by intake valve 30, drying cylinder 3 utilizes the heat of steam to be dried by paper, steam is also lowered the temperature condensation, to enter in steam releasing silencer 6 cooling further by air outlet valve 31 with steam pipework 2 to be again in a liquid state water, aqueous water enters in Sewage treatment circulating device 8 and filters, enters steam turbine 1 recycle by the water inlet 10 of steam turbine 1 after pressurized treatments.
