Abstract
An ash-removal brush assembly for a submerged arc furnace type heat recovery boiler is arranged among a heat exchange tube set, and comprises two supporting plates, an ash-removal steel wire ball and two bars of hold-down plates. A 5 to 20MM gap is arranged between the supporting plates and the heat exchange tube set. The ash-removal steel wire is clamped by the supporting plates and is disposed at the gap between the supporting plates and the heat exchange tube set. The supporting plates belong to bar-shaped supporting plates provided with inner grooves at the upper sides and the down sides of the plates. The number and the position of the inner grooves are corresponding to the number and the position of each heat exchange tube of the heat exchange tube set. The supporting plates are provided with location holes. The two bar-shaped hold-down plates having the same length as the supporting plates are fixedly screwed into the location holes via bolts so that the ash-removal steel wire ball is clamped and fixed by the supporting plates. The ash-removal brush assembly for the submerged arc furnace type heat recovery boiler of the utility model is high in versatility. The supporting plates with different dimensions can be employed according to actual gaps among the heat exchange tube set. Replacing is convenient and cleaning effect is fine. Service life of the steel wire ball is correspondingly prolonged, and waste heat utilization efficiency of the submerged arc furnace type heat recovery boiler is substantially improved.

The hot type of furnace waste heat boiler deashing brush assemblies in a kind of ore deposit comprises the uniform set of heat exchange tubes that is spaced type that is that is arranged in the hot type of furnace waste heat boiler in ore deposit, it is characterized in that:
Be provided with a deashing brush assemblies between the described set of heat exchange tubes, this deashing brush assemblies is made up of with steel wire lump and two pressing plates two blocks of supporting plates, deashing, leaves 5～20MM gap between supporting plate and the set of heat exchange tubes;
Described supporting plate is deashing steel wire lump clamping, and this deashing is placed in the gap of above-mentioned supporting plate and 5～20MM between the set of heat exchange tubes with steel wire lump.
According to the hot type of furnace waste heat boiler deashing brush assemblies in a kind of ore deposit of the present utility model, it is characterized in that, both sides all were provided with the supporting plate of the strip of inner groovy about described supporting plate was specially, the size of its inner groovy is slightly larger than the diameter of every heat exchanger tube of set of heat exchange tubes, and the quantity of inner groovy and position are corresponding with the quantity and the position of every heat exchanger tube of set of heat exchange tubes.
The size of the inner groovy of She Ji supporting plate is slightly larger than the diameter of every heat exchanger tube of set of heat exchange tubes herein, be above-mentioned " leaving 5～20MM gap between supporting plate and the set of heat exchange tubes ", and this has the supporting plate of the strip of inner groovy, purpose is deashing is held with steel wire lump, increase the rigidity and the toughness of steel wire lump, make the steel wire lump cleaning effect better, and be difficult for sliding and drooping.
According to the hot type of furnace waste heat boiler deashing brush assemblies in a kind of ore deposit of the present utility model, it is characterized in that, described supporting plate has locating hole, and two pressing plates with the supporting plate equal length are screwed in this locating hole and fixing by bolt, makes the supporting plate clamping and fixes the deashing steel wire lump.
Pressing plate and supporting plate cooperatively interact, make the supporting plate deashing steel wire lump that can be clamped, the purpose of this design has been to guarantee supporting plate intensity at high temperature, can make it that certain elasticity is arranged again, both guarantee the intensity of deashing brush, and can not produce the stuck phenomenon between supporting plate and the set of heat exchange tubes.
In addition, the utility model can adopt the supporting plate of different size according to the concrete interval situation of set of heat exchange tubes, is convenient for changing.
Use the hot type of furnace waste heat boiler deashing brush assemblies in a kind of ore deposit of the present utility model, obtain following beneficial effect:
Deashing with steel wire lump no longer produce as under the prior art not with the situation that every heat exchanger tube contacts or contact point slowly tails off of set of heat exchange tubes, but be clamped in middle by two supporting plates, increase the rigidity of steel wire lump, guarantee that steel wire lump contacts with every heat exchanger tube, make that its cleaning effect is better, and be difficult for to slide and droop, the service life of steel wire lump also corresponding the prolongation.
2. by the newly-designed pressing plate of counterweight and supporting plate being used between the two, make it guarantee the intensity of supporting plate, it is had under certain elasticity situation, can not produce the stuck phenomenon between supporting plate and the set of heat exchange tubes at high temperature.
3. the hot type of furnace waste heat boiler deashing brush assemblies in ore deposit of the present utility model, its versatility height can adopt the supporting plate of different size according to the concrete interval situation of set of heat exchange tubes, is convenient for changing.
