Abstract
The wind collecting box type helical wind-guiding hot air stove is provided with a cylindrical furnace body, the external wall of the furnace body is wrapped by an outer cylinder, and a jacket layer is arranged between the external wall and the outer cylinder of the furnace body. A cylindrical wind collecting box is arranged on the upper part in the furnace cavity. The inlets of the wind collecting box are uniformly distributed along the periphery below the wind collecting box, and the outlets of the wind collecting box are uniformly distributed along the periphery above the wind collecting box. A jacket baffle is arranged among the jacket, the inlets of the wind collecting box and the outlets of the wind collecting box, dividing the jacket into an upper jacket and a lower jacket. Radial helix wind-guiding pieces are arranged among the lower jacket, the external wall of the furnace body and the inner wall of the outer cylinder. The inlets of the wind collecting box are communicated with the lower jacket, and the outlets of the wind collecting box are communicated with the upper jacket. Cold air inlets are positioned beside the lower jacket, and hot air outlets are positioned beside the upper jacket. The heat exchanger device of the utility model has a jacket heat-exchanger and a wind collecting box heat-exchanger. The helix wind-guiding pieces are arranged in the jacket heat-exchanger, and the wind collecting box is arranged above the furnace cavity, which makes the most of the radiant heat and the convected heat when the coal burns in the furnace cavity. The heat exchanger is uneasy to be blocked up by flue dust, the heat exchange area is larger, and the heat efficiency is higher.
Description
Technical field
The utility model relates to the heat-exchanger rig of a kind of coal-fired hot-blast stove, particularly a kind of coal-fired hot-blast stove.
Background technology
The interior heating of indoor or green house of vegetables has coal furnace and heat-exchanger rig with coal-fired hot-blast stove.Coal furnace has body of heater, and sidewall of the furnace body has fire door, and there is the lime-ash door sidewall of the furnace body fire door below, between the fire door in the body of heater and lime-ash door fire grate is arranged, and has chimney, coal furnace to be connected with heat-exchanger rig with air above the body of heater.In the prior art, heat-exchanger rig has the shell and tube heat-exchanger rig, walks pyrotechnics in the pipe of shell and tube heat-exchanger rig, walks air outside the pipe.This coal-fired hot-blast stove not only thermal efficiency is not high, and heat exchanger tube is very easily stopped up by cigarette ash in use, and influence is used.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of thermal efficiency height, and heat exchanger tube is difficult for the wind collecting box type helical wind-guiding coal-fired hot-blast stove that stopped up by cigarette ash in use.
The utility model is realized with the following method.
Wind collecting box type helical wind-guiding coal-fired hot-blast stove has cylindrical furnace, there is burner hearth at the body of heater middle part, burner hearth sidewall has fire door, there is the lime-ash door fire door below, between fire door in the body of heater and lime-ash door fire grate is arranged, there is chimney the body of heater top, be surrounded by urceolus at furnace body outer wall, be the chuck layer between furnace body outer wall and urceolus, there is cylindrical shape collection wind box the top in the burner hearth, and collection wind box below is uniformly distributed with collection wind box inlet along the circumference, collection wind box top is uniformly distributed with the outlet of collection wind box along the circumference, in the chuck, collecting between wind box inlet and the outlet of collection wind box has the chuck dividing plate, and the chuck dividing plate is divided into chuck and following chuck two parts to chuck, in following chuck, radially helical wind-guiding sheet is arranged between furnace body outer wall and outer tube inner wall, collection wind box inlet is connected with following chuck, the outlet of collection wind box is connected with last chuck, and following jacket side has cool air inlet, and last jacket side has hot air outlet.
During use, coal-fired in burner hearth, heating jacket and collection wind box, cold air is blasted chuck from cool air inlet, cold air is being heated along the rising of helical wind-guiding sheet in the chuck down, enter collection wind box from collection wind box inlet, further be heated, enter chuck from the outlet of collection wind box and spray through hot air outlet at collection wind box.
Heat-exchanger rig of the present utility model has chuck heat exchanger and collection wind box heat exchanger, and the helical wind-guiding sheet is arranged in the chuck heat exchanger, and there is collection wind box the burner hearth top, made full use of radiant heat and the advection heat of coal in the burner hearth internal combustion, heat exchanger is difficult for being stopped up by cigarette ash, and heat exchange area is bigger, thermal efficiency height.
Below in conjunction with accompanying drawing, the utility model is further described.
