The present invention can solve the energy-conservation recovery problem of vacuum boiler two groups of built-in heat exchanger flue gas condensings, and two road water access heat exchangers all can obtain energy independently of one another, keep each self-balancing, mutually not interference; Utilize alternately arranging of heat exchanger tube, solve the style of flue gas and hot water heat exchange, solve the assignment problem of each technical parameters such as two heat exchanger energy, temperature, flows, solve the problem of two road water differences service time and initiation; It has reasonable structural arrangement, easy to use and reliable, can meet the features such as flue gas two condenser energy saving requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, the water-cooled flue gas condenser in a kind of double loop of the present invention, it mainly comprises the middle housing 2 with exhaust gases passes 1 and the gas approach 3 be communicated with respectively by exhaust gases passes 1 in housing 2 left and right sides and exhanst gas outlet 4, the sidewall of housing 2 is respectively arranged with cooling water inlet and outlet, and is connected by the heat exchanger tube be built in exhaust gases passes 1 between described cooling water inlet and outlet; Described housing 2 sidewall is respectively arranged with two cooling water inlets and outlet, wherein the first cooling water inlet 5 is connected respectively by the first built-in heat exchanger tube 7 with outlet 6, second cooling water inlet 8 is also connected by the second built-in heat exchanger tube 10 with outlet 9, the alternately arrangement along flow of flue gas direction respectively of the first described heat exchanger tube 7 and the second heat exchanger tube 10; Bottom in described housing 2 is also provided with the floss hole 11 of discharging for condensed water.
Shown in figure, the top and the bottom of housing 2 of the present invention are respectively arranged with upper perforated plate 18 and upper cover plate 12, lower perforated plate 19 and lower cover 13, and at upper perforated plate 18 and upper cover plate 12, lateral arrangement is respectively arranged with between lower perforated plate 19 and lower cover 13, the the first cooling water intake chamber 14 put between the upper and lower, second cooling water intake chamber 15 and the first cooling water water-supplying chamber 16, second cooling water water-supplying chamber 17, the first cooling water inlet 5 that wherein lower cover 13 side is arranged is communicated with through the first cooling water intake chamber 14, the first heat exchanger tube 7 be arranged in exhaust gases passes 1 by many transverse directions is again communicated with the first cooling water water-supplying chamber 16 in upper cover plate 12, and the first coolant outlet 6 be communicated with the first cooling water water-supplying chamber 16 is provided with in upper cover plate 12 side, the first described heat exchanger tube 7 and the second heat exchanger tube 10 are welded on described upper perforated plate 18 and lower perforated plate 19 respectively.
