Description

A kind of waste gas residual heat recycling and processing device
Technical field
The utility model relates to a kind of emission-control equipment, particularly a kind of waste gas residual heat recycling and processing device.
Background technology
Coke oven is the critical facility of coke-oven plant, the most of directly mode of heating of burning such as coal or coal gas that adopts of coke oven of coke-oven plant, under this mode of heating, coal or coal gas can produce a large amount of high-temp waste gas after burning, the temperature of waste gas can reach 300 ℃ of left and right, and the waste gas that coke oven produces contains a large amount of heat energy.At present, the high-temp waste gas that the coke oven of coke-oven plant produces is directly discharged in atmosphere by chimney, has so just caused a large amount of heat energy loss, is unfavorable for effective utilization of the energy.Therefore, how to reclaim the heat energy of coke oven exhaust gas, realize the secondary utilization of the energy, become particularly important.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and a kind of waste gas residual heat recycling and processing device is provided.
The technical solution of the utility model is: a kind of waste gas residual heat recycling and processing device, comprise for transmitting the air intake duct of waste gas and for discharging the exhaust duct of flue gas, air intake duct is connected with the flue gas gas outlet of coke oven, in air intake duct, be provided with cooling water tank, on cooling water tank, be respectively equipped with water inlet pipe and outlet pipe, the water inlet pipe other end is connected with cold water holding vessel, and the outlet pipe other end is connected with hot water storage tank.
Further, air intake duct is divided into forward and backward two parts, and rear section air intake duct internal diameter is greater than forward part air intake duct, and cooling water tank is arranged in the air intake duct of rear section.
Further, exhaust duct end is provided with multiple filtration net, filters mesh number between 50-200.
Further, between water inlet pipe and cold water holding vessel, be provided with water intaking valve, between outlet pipe and hot water storing tank, be provided with outlet valve.
Further, cooling water tank is made by iron sheet.
The beneficial effects of the utility model are: the utility model device adopts water-cooled mode to recycle the waste heat in waste gas, and simple and practical, cost is low, easy to utilize.
Accompanying drawing explanation
Fig. 1 is the utility model apparatus structure schematic diagram;
The concrete meaning of number in the figure is: 1, coke oven, 2, air intake duct, 3, cooling water tank, 4, cooling water holding vessel, 5, hot water storing tank, 6, exhaust duct, 7, water inlet pipe, 8, outlet pipe, 9, water intaking valve, 10, outlet valve, 11, screen pack.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model device is described further, as shown in Figure 1, for waste gas residual heat recycling and processing device, comprise for transmitting the air intake duct 2 of waste gas and for discharging the exhaust duct 6 of flue gas, air intake duct 2 is connected with the flue gas gas outlet of coke oven 1, is provided with cooling water tank 3 in air intake duct 2, is respectively equipped with water inlet pipe 7 and outlet pipe 8 on cooling water tank 3, water inlet pipe 7 other ends are connected with cold water holding vessel 4, and outlet pipe 8 other ends are connected with hot water storage tank 5.Air intake duct 2 is divided into forward and backward two parts, rear section air intake duct internal diameter is greater than forward part air intake duct, cooling water tank 3 is arranged in the air intake duct of rear section, can effectively slow down the flowing velocity of waste gas like this, and increase the contact area of cooling water tank and waste gas, improve heat conduction efficiency, in order further to improve heat conduction efficiency, cooling water tank can be made by the good material of the thermal conduction effects such as iron sheet.Exhaust duct end is also provided with multiple filtration net, filters mesh number between 50-200, can simply effectively filter out the particle foreign material in waste gas like this.Between water inlet pipe and cold water holding vessel, be provided with water intaking valve, between outlet pipe and hot water storing tank, be provided with outlet valve, play adjusting control action.
