Abstract
The utility model relates to a paper drying device, in particular to a gas supply device for drying paper. In the gas supply device for drying paper, a gas decompression device is connected with a gas buffer tank by a gas pipeline, and the output end of the gas buffer tank is communicated with an infrared heater by the gas pipeline. In the gas supply device for drying paper, the gas buffer tank is increased on the gas pipeline. When pressure in the gas supply pipeline instantly changes, pressure in the gas buffer tank makes little change, and gas pressure at the inlet of the infrared heater can be controlled; therefore, the extinguishing possibility of the infrared heater is reduced, gas flow rate can be effectively prevented from having rapid change, and the work stability of the whole system is improved. Besides, gas storage quantity in the pipeline is increased, the instant ignition success rate of the infrared device is effectively improved, the running efficiency of the infrared device is further ensured, and the frequent ignition times of the infrared device ignition system is reduced.
Description
Technical field:
The utility model relates to a kind of papermaking dry device, relates in particular to a kind of papermaking dry feeder.
Background technology:
At present, in paper, need paper pulp is carried out heat drying.Heating and drying method has multiple, as electromagnetism heating, infrared ray heating etc.Its middle infrared (Mid-IR) heating need be by supplying combustion gas in infrared heater.Combustion gas is directly supplied in current employing in infrared heater.In daily production process, because the gas supply pressure imbalance, if infrared heater generation fire extinguishing situation, the instantaneous ignition success rate is low, reduce the normal service life of infrared heater like this, increased the maintenance cost of equipment, the consumption that has strengthened material.
Summary of the invention:
The purpose of this utility model provides a kind of device that can balance gas supply pressure, reduces the generation of infrared heater generation fire extinguishing situation.
The technical scheme that the utility model provides is:
The papermaking dry feeder, gas pressure reducingequipment connects the combustion gas surge tank by gas pipeline, and the output port of combustion gas surge tank is communicated with infrared heater by gas pipeline.
The combustion gas surge tank is connected by the controllable valve door by two tank bodies, and tank body 1 is provided with the interface that joins with gas pressure reducingequipment, and tank body 2 is provided with valve and is connected and water discharge outlet with infrared heater.
The utility model has increased the combustion gas surge tank on gas transmission line, when the pressure instantaneous variation inside the air feed circuit, the pressure of combustion gas surge tank the inside changes very little, can control the pressure of infrared heater inlet gas, reduce infrared heater fire extinguishing situation odds, and can effectively prevent the gas flow rate acute variation, guarantee that the whole system job stability improves.Improve the infrared heater working life like this, reduced cost of equipment maintenance, saved spending.In addition, increase gas storage amount in the pipeline, effectively improve infrared facility instantaneous ignition success rate, further ensured the operational efficiency of infrared facility, reduced the frequent igniting number of times of infrared facility ignition system.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 gas pressure reducingequipment, 2 infrared heaters, 3 interfaces, 4 tank body a, 5 controllable valve doors
6 tank body b, 7 water discharge outlet, 8 valves, 9 gas pipelines
The specific embodiment
Introduce the technical solution of the utility model in detail below in conjunction with specific embodiment.
As shown in Figure 1, gas pressure reducingequipment 1 links to each other with the interface 3 of tank body a4 by gas pipeline 9.Tank body a4 links to each other with tank body b6 by controllable valve door 5.The bottom of tank body b6 is provided with water discharge outlet 7.Tank body b6 is communicated with the gas pipeline 9 that is connected with the infrared heater air inlet by valve 8
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
