Delivery port is provided with the three-temperature sensor of measurement discharge coolant-temperature gage, is additionally provided with and is sensed with the first temperature sensor, second temperature
The control unit that device, three-temperature sensor are connected with water regulator.
The improvement of technical solution of the present invention is further used as, the bottom in housing is provided with the drain bar being obliquely installed, and is located at
The drain valve on housing is provided with below drain bar.
Be further used as the improvement of technical solution of the present invention, spiral coil is arranged in housing in the shape of a spiral, water inlet and
Delivery port extend out to hull outside.
Beneficial effects of the present invention：This boiler integrated form flue gas energy recycle device is by the cavity for entering housing
High-temperature flue gas and the condensed water in spiral coil is heated by carrying out heat transfer between the condensed water in spiral coil, and
Multiple temperature sensor real-time detection flue gas discharge temperatures and condensed water discharge temperature are connected by control unit to control water
The unlatching size of adjuster, it is ensured that when heat transference efficiency reaches maximum, exhanst gas outlet discharge waste gas in oxynitrides and
Hydrocarbon is minimum, reaches the double effectses for improving rate of heat exchange and environmental protection.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings：
Fig. 1 is embodiment of the present invention overall structure diagram.
Specific embodiment
Reference picture 1, the present invention is a kind of boiler integrated form flue gas energy recycle device, including internal is what cavity was set
Housing 1, housing 1 is respectively arranged at two ends with the smoke inlet 2 and exhanst gas outlet 3 communicated with cavity, and water inlet is additionally provided with housing 1
4 and delivery port 5, the spiral coil 6 of connection water inlet 4 and delivery port 5 is provided with housing 1, water inlet 4 is provided with water regulator 7,
Smoke inlet 2 is provided with the first temperature sensor 8 that measurement enters the flue gas temperature of housing 1, and exhanst gas outlet 3 is provided with measurement discharge
The second temperature sensor 9 of the flue gas temperature of housing 1, delivery port 5 is provided with the three-temperature sensor of measurement discharge coolant-temperature gage,
It is additionally provided with and is connected with the first temperature sensor 8, second temperature sensor 9, three-temperature sensor 10 and water regulator 7
Control unit.
This boiler integrated form flue gas energy recycle device is by the high-temperature flue gas in the cavity for entering housing 1 and by spiral shell
Heat transfer is carried out between the condensed water in capstan pipe 6 to heat the condensed water in spiral coil 6, and is connected by control unit
Multiple temperature sensor real-time detection flue gas discharge temperatures and condensed water discharge temperature is connect to control the unlatching of water regulator 7 big
Small, it is ensured that when heat transference efficiency reaches maximum, oxynitrides and hydrocarbon in the waste gas of the discharge of exhanst gas outlet 3 are most
