Abstract

The utility model discloses a deduster blowing air tank structure, which comprises a deduster blowing air tank; wherein, the blowing air tank is provided with an air inlet and a blowdown valve; a plurality of air ducts are evenly arranged on the blowing air tank; pulse valves are mounted through the air ducts; and when the minimum working capacity of the air tank is enough for a single pulse valve to blow for one time, the working pressure in the air tank is reduced to 60 percent to 80 percent of the original working pressure. The capacity of the air tank is designed according to the minimum, the minimum size of the air tank is determined, and then, on the basis, the size of the air tank is enlarged. Consequently, not only the normal operation of the whole blowing system is ensured, and but also the rationality of material and labor cost is ensured.

Description

Deduster winding-up gas bag structure
Technical field
The utility model relates to a kind of deduster structure, particularly a kind of deduster winding-up gas bag structure.
Background technology
In the design of deduster, winding-up gas bag volume controlled is very important.If the gas bag capacity is less than normal, when first pulse valve during in the winding-up operation, gas bag compressed air pressure descends very fast, and when next pulse valve winding-up, the gas bag internal gas pressure has little time to replenish back original pressure state.This just causes whole injection system cisco unity malfunction, has influenced the ash-removal effect of deduster.Otherwise,,, very uneconomical with causing the waste of material and cost of labor if the gas bag capacity is excessive.
The utility model content
The utility model technical issues that need to address just are to provide a kind of deduster winding-up gas bag structure, and it can guarantee the operate as normal of whole injection system, has guaranteed the reasonability of material and cost of labor again.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of deduster winding-up of the utility model gas bag structure, comprise deduster winding-up gas bag, described winding-up gas bag is provided with air inlet and blowoff valve, evenly be furnished with the multiple tracks wireway on the described winding-up gas bag, by wireway pulse valve is installed, the minimum displacement volume of described gas bag for individual pulse valve winding-up once after, the operating pressure in the gas bag drops to the 60-80% of former operating pressure.When carrying out the design of gas bag capacity, design by minimum capacity, determine the minimum volume of gas bag, then on this basis, the volume of gas bag is carried out dilatation.Like this, promptly guarantee the operate as normal of whole injection system, guaranteed the reasonability of material and cost of labor again.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of deduster winding-up of the utility model gas bag structure, comprise deduster winding-up gas bag 1, described winding-up gas bag is provided with air inlet 2 and blowoff valve 3, evenly be furnished with multiple tracks wireway 4 on the described winding-up gas bag, pulse valve be installed, identified pulse valve installation site 5 among Fig. 1 by wireway, the minimum displacement volume of described gas bag for individual pulse valve winding-up once after, the operating pressure in the gas bag drops to the 60-80% of former operating pressure.When carrying out the design of gas bag capacity, design by minimum capacity, determine the minimum volume of gas bag, then on this basis, the volume of gas bag is carried out dilatation.Like this, promptly guarantee the operate as normal of whole injection system, guaranteed the reasonability of material and cost of labor again.
For instance, use the Shanghai bag to join 4 cun submerged pulse valves of production, under the operating pressure of 0.5MPa, this pulse valve winding-up tolerance 500L (standard atmospheric pressure), so in fact, compression tolerance under the duty that this pulse valve consumed is: 500 * 0.1/0.5=100L (0.1MPa is a standard atmospheric pressure, and 0.5MPa is an operating air pressure).
Below be computational process.
(1) air pressure before the pulse valve winding-up: P 0=0.5MPa
(2) air pressure after the pulse valve winding-up: P 1=0.5 * 70%=0.35MPa
(3) the winding-up tolerance of pulse valve: 100L (under the operating pressure)
(4) the gas bag volume before the winding-up: V 0=undetermined
(5) the gas bag volume after the winding-up: V 0-100 is undetermined
(6), remainder compressed air there is following formula according to the airflow balance equation:
P 0(V 0-100)=P 1V 0
(7) substitution numerical value gets V 0=P 0* 100/ (P 0-P 1)=333L
That is, gas bag capacity minimum of a value is 333L.In actual design, the gas bag capacity is decided to be 350L.Guaranteed good winding-up effect.
And in the actual engineering application, in Puyang three strongest ones dedusting project injection system, the specification 377 * 2590 of this gas bag, its capacity is only less than 280L, and when causing pressing (0.5MPa) winding-up in 4 cun pulse valves, gas bag pressure descends very fast.Afterwards, the pipe arrangement pipeline is increased to 3 cun by 2 cun, and was equivalent to whole pipe-line system and has become an air accumulator, the situation that jetting pressure reduces just improves.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
