Abstract
The utility model discloses a cross support flying ash blowing device, which comprises a cross support, a cover plate and a water-cooled pipe, wherein the cover plate is arranged below the cross support, the water-cooled pipe is arranged at the periphery of the cover plate, a high-pressure air source pipe is arranged at the center of the cross support, the lower end of the high-pressure air source pipe is communicated with a bell-mouth shaped air distribution cover, the lower end of the bell-mouth shaped air distribution cover is closed, and a circle of blowing hole is arranged at the lower part of the side face of the bell-mouth shaped air distribution cover. The flying ash blowing device is simple in structure and is convenient to operate and implement, ash accumulation can be effectively prevented, system suitability can be improved, and system operational flexibility can be greatly improved; and a main throttling orifice plate and an auxiliary throttling orifice plate are arranged on the high-pressure air source pipe in parallel, an ash blowing effect can be improved, and a blowing hole is prevented from being plugged.
Description
Technical field
The utility model belongs to technical field of chemical, particularly a kind of cross hang flying dust purging device.
Background technology
Because ature of coal is unstable, there is certain difficulty in coal blending, makes the caking property of part flying dust strong; In the situation that the ature of coal fluctuation occurs, the manual adjustments carbon ratio lags behind, and causes the gasification burner temperature higher, so that the viscosity of flying dust is larger, thereby up and down pressure-difference fluctuation of cross hang occurs, even the situation of dust stratification occurs in cross hang place.The flying dust zone of easy appearance is: the cover plate place of cross hang place of syngas cooler entrance, syngas cooler entrance and the top of hot coil.
Status analysis from dust stratification: the dust stratification position is mainly the top of hot coil, and from the superheat section downside, then slowly accumulation, and radiate out stops up whole passage.At present, soot blower only is used for removing the dust stratification at cross suspension bracket middle part, synthesis gas purges ability and successively decreases successively to the center from water-cooling wall, it is very low to cause like this center to purge ability, and heat exchange is in bad order, causes the center temperature higher, form the grey point of knot, in case centre knot ash because the character of flying dust itself can very fast radiate out, and then stops up whole passage.
The utility model content
The utility model provide a kind of simple in structure, easy and simple to handle, be convenient to implement and adaptable cross hang flying dust purging device.
For achieving the above object, the technical solution of the utility model is: cross hang flying dust purging device, comprise cross hang, the cover plate of cross hang below and the water cooling tube around the cover plate, described cross hang center is provided with the high pressure gas source capsule, high pressure gas source capsule lower end is communicated with the bell mouth shape cloth fan housing of lower end closed, and bottom, bell mouth shape cloth fan housing side is provided with a circle blow valve port.
Be provided with side by side main restriction orifice and secondary restriction orifice on the described high pressure gas source capsule.
Described bell mouth shape cloth fan housing is between cross hang and cover plate.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises cross hang, the cover plate of cross hang below and the water cooling tube around the cover plate, described cross hang center is provided with the high pressure gas source capsule, high pressure gas source capsule lower end is communicated with the bell mouth shape cloth fan housing of lower end closed, bottom, bell mouth shape cloth fan housing side is provided with a circle blow valve port, and it is simple in structure, and is easy and simple to handle, be convenient to implement, can effectively avoid occuring fouling phenomenon, can strengthen system suitability, system's operating flexibility can promote greatly.
2, be provided with side by side main restriction orifice and secondary restriction orifice on the high pressure gas source capsule, can strengthen and blow grey effect and prevent that blow valve port from stopping up.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Cross hang flying dust purging device as shown in Figure 1, it comprises the cover plate 5 of cross hang 1, cross hang 1 below and the water cooling tube 6 around the cover plate 5, be provided with high pressure gas source capsule 2 in cross hang 1 center, the lower end of high pressure gas source capsule 2 is communicated with the bell mouth shape cloth fan housing 3 of lower end closed, bell mouth shape cloth fan housing 3 is between cross hang 1 and cover plate 5, be provided with a circle blow valve port 4 in the bottom, side of bell mouth shape cloth fan housing 3, the diameter of blow valve port 4 is 5mm, and cleaning and perturbation action are played in cover plate 5 top center positions.To blow grey effect and prevent that blow valve port 4 from stopping up in order to strengthen, be provided with side by side main restriction orifice 7 and secondary restriction orifice 8 on high pressure gas source capsule 2, main restriction orifice 7 is 129mm, and secondary restriction orifice 8 is 94mm.
Claims (3)
1. cross hang flying dust purging device, comprise cross hang, the cover plate of cross hang below and the water cooling tube around the cover plate, it is characterized in that: described cross hang center is provided with the high pressure gas source capsule, high pressure gas source capsule lower end is communicated with the bell mouth shape cloth fan housing of lower end closed, and bottom, bell mouth shape cloth fan housing side is provided with a circle blow valve port.
