Abstract
The invention discloses hot blast equipment. The hot blast equipment comprises a hot blast boiler; a fume outlet of the hot blast boiler is connected with a chimney through a chimney flue; a dust remover is connected onto the chimney flue in series, and comprises a spraying box body and a reflow box body which are traversed by the chimney flue sequentially; the chimney flue traverses from the upper parts of the spraying box body and the reflow box body; a sprayer is arranged at the front end of the spraying box body on the chimney flue; the bottom of the reflow box body is higher than the bottom of the spraying box body; a passage which is inclined downward is formed in the bottom of the reflow box body, and is communicated with the spraying box body; the bottom of the spraying box body is communicated with the sprayer through a water pump. Compared with the prior art, the hot blast equipment can solve the problem that conventional hot blast equipment is not good in filter effect, and is not suitable for dust removal of high-temperature flue gas.
Description
Technical field
The present invention relates to chemical industry equipment manufacturing technology field, especially a kind of heated-air drying equipment that is used to chemical products.
Background technology
At present, the heated-air drying equipment that existing chemical enterprise uses, generally all comprises hot air boiler, and the exhanst gas outlet of hot air boiler connects chimney by flue, is in series with deduster on flue, and flue gas chimney is discharged.Due to from hot air boiler flue-gas temperature out all higher than 60 DEG C, dedusting part active carbon and screen pack in deduster easily damage, and temperature affects the suction-operated of active carbon, and filter effect is not good, thereby the flue gas flue dust impurity that causes heated-air drying equipment to be discharged is many, seriously polluted.
Summary of the invention
Problem to be solved by this invention is to provide a kind of blast heater, many to solve the flue gas flue dust impurity that existing blast heater discharges, with serious pollution problem.
In order to address the above problem, technical scheme of the present invention is: this blast heater includes hot air boiler, the exhanst gas outlet of described hot air boiler connects chimney by flue, on described flue, be in series with deduster, described deduster includes the spraying casing and the backflow casing that are passed across by flue successively, described flue crosses from the top of described spraying casing top and described backflow casing, described flue is provided with sprayer in the front end of described spraying casing, the bottom of described backflow casing is higher than the bottom of described spraying casing, passage under the bottom of described backflow casing is provided with and is tilted to is communicated with described spraying casing, the bottom of described spraying casing is communicated with described sprayer by water pump.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
The deduster of this blast heater adopts sprayer and spraying casing and backflow casing, utilizes flue dust and the impurity of water smoke absorption flue gas in flue, plays the effect of good filtering smoke; When most flue-gas temperatures are higher, the water of spraying casing is by high-temperature atomizing, flue dust in automatic absorbing flue gas, use if desired water pump to supply water to sprayer, the interior water smoke of flue has carried flue dust and has fallen, arrive backflow casing, be back to spraying casing after pooling water, the temperature of flue gas is also minimized simultaneously.Deduster is simple in structure, easy to use, and use cost is low.The flue gas flue dust impurity that this blast heater is discharged is few, pollutes lighter.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the structural representation of embodiment of the present invention deduster.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
Blast heater as shown in Figure 1 comprises hot air boiler 11, and the exhanst gas outlet of hot air boiler 11 connects chimney 13 by flue 1, is in series with deduster 12 on flue 1.As shown in Figure 2, it includes the spraying casing 3 and the backflow casing 5 that are passed across by flue 1 successively to deduster 12, utilizes flue dust and the impurity of flue gas in water smoke absorption flue 1, plays the effect of good filtering smoke.Flue 1 crosses from the top of spraying casing 3 tops and backflow casing 5, flue 1 is provided with sprayer 2 in the front end of spraying casing 3, the bottom of backflow casing 5 is higher than the bottom of spraying casing 3, passage 4 under the bottom of backflow casing 5 is provided with and is tilted to is communicated with spraying casing 3, and the bottom of spraying casing 3 is communicated with sprayer 2 by water pump 6.When most flue-gas temperatures are higher, the water of spraying casing 2 is by high-temperature atomizing, flue dust in automatic absorbing flue gas, use if desired water pump 6 to supply water to sprayer 2, the interior water smoke of flue has carried flue dust and has fallen, arrive backflow casing 5, be back to spraying casing 3 after pooling water, the temperature of flue gas is also minimized simultaneously.
Claims (1)
1. a blast heater, include hot air boiler, the exhanst gas outlet of described hot air boiler connects chimney by flue, on described flue, be in series with deduster, it is characterized in that: described deduster includes the spraying casing and the backflow casing that are passed across by flue successively, described flue crosses from the top of described spraying casing top and described backflow casing, described flue is provided with sprayer in the front end of described spraying casing, the bottom of described backflow casing is higher than the bottom of described spraying casing, passage under the bottom of described backflow casing is provided with and is tilted to is communicated with described spraying casing, the bottom of described spraying casing is communicated with described sprayer by water pump.
