Description
Technical field
The present invention relates to a kind of flue gas cooling device.
Background technology
Environmental protection industry (epi) runs into some high-temperature flue gas through regular meeting aspect flue gas ash removal, will cause the damage of equipment or the decline in service life, especially sack cleaner if the flue gas of excessive temperature directly enters cleaner.The industrial cooling measure of taking usually has: one, replenish normal temperature air and carry out adjustment in flue; Two, the air chamber of larger capacity is set in flue, reduces flue gas flow rate suddenly, allow flue gas circuitous delay in air chamber, reduce flue-gas temperature naturally; Three, flue is penetrated cyclic water tank or pond cooling or the like.Although cooling effect is in various degree all arranged, quite few for afterheat utilization, have in addition must increase consumption.How to improve cooling effectiveness, and make full use of its waste heat in the flue gas cooling, this has certain realistic meaning for carrying out environmental protection economy.
Summary of the invention
The invention provides a kind of flue gas cooling device, its main purpose is in order to reduce the temperature of flue gas, to ensure the deduster safe operation, the heat energy displacement feedwater of flue gas can being utilized simultaneously again.Modern design of the present invention, gas, waterpipe have a style of one's own, and adopt the form of water spray cooling flue to carry out heat exchange, and the mutually noninterfere of cigarette G﹠W makes cooling water remain cleaning; Adopt thin water smoke spray, cooling-down effect is good, and water consumption is less, and has the function of two grades of hot water of separate collection height, in order to expanding between the hot water application area, reaches the purpose of energy-saving and emission-reduction comprehensive utilization heat energy.
In order to address the above problem, the present invention is achieved through the following technical solutions, and it is made up of up-hole plate, top cover, sealing gasket, water inlet pipe, pressure-reduction outlet, coaming plate, thermal insulation board, orifice plate, outlet pipe, fume pipe, subregion plate, shoot door, doormat, base plate, shower.Be divided into inlet chamber, conversion chamber, spray chamber, outlet chamber by operation interval; And be provided with air inlet, gas outlet, cleaning door.Integral body of the present invention is vertical cabinet, the outside is formed by coaming plate and base plate welding, and inner chamber divides three layers of upper, middle and lowers, is separated by up-hole plate and orifice plate, the upper strata is flue gas conversion chamber, the middle level is water spray chamber, and lower floor is separated into inlet chamber and outlet chamber with the subregion plate, aligns one by one in the hole of last orifice plate, fume pipe docks with the aperture of last orifice plate, conversion chamber and inlet chamber, outlet chamber are connected, and the welding in the mouth of pipe and aperture should be solid and reliable, and pore must not be arranged; Establish air inlet and gas outlet respectively on the coaming plate of inlet chamber and outlet chamber, be connected with outside flue, and be provided with cleaning door, cleaning door seals with shoot door and doormat.The shower of directional profile atomizing spray water is set above the spray chamber, is connected with water inlet pipe; The below in spray chamber is separated in two with thermal insulation board, to collect the hot water of heat exchange gained different temperatures; The bottom in spray chamber sets out water pipe, and top also is provided with pressure-reduction outlet.Above the conversion chamber, be provided with sealing gasket and top cover, for the usefulness of dredging the fume pipe dust stratification.
High-temperature flue gas is discharged through inlet chamber, fume pipe, conversion chamber, fume pipe to gas outlet circulation from air inlet.Cooled off by the shower shower water at twice during by fume pipe, shower water has gathered certain heat energy after fume pipe tube wall and flue gas heat exchange, flue-gas temperature in the interval fume pipe of difference is also different, with twice hot water separate collection, be beneficial to the use of different occasions by the fume pipe gained.
