Abstract
The utility model discloses a boiler afterheat recovery and dust removal device, which comprises a water storage tank and a heat exchanger arranged in the water storage tank, a fume inlet, a fume outlet, a water inlet pipe, a water outlet pipe and an exhaust pipe arranged on the water storage tank, wherein, the fume inlet and the fume outlet are communicated through the heat exchanger, the heat exchanger is composed of an air inlet connecting box, an air outlet connecting box, a heat exchanger and a buffering settlement box, the air inlet connecting box and the air outlet connecting box are arranged at the upper part of the water storage tank, and respectively connected with the fume inlet and the fume outlet, the buffering settlement box is arranged at the lower part of the water storage tank, a dust removal opening is arranged at the bottom part of the water storage tank, and the air inlet connecting box and the air outlet connecting box are communicated through the heat exchanger and the buffering settlement box. Most of fume is displaced into the water in the water storage tank when the high temperature fume passes through, the heat recovery rate is high, the temperature of the heat exchanger is relatively low when being dipped into the water, the service life is long, the heat recovery rate of the utility model is high, the service life is high, and the utility model has both the recovery of waste heat function and the dust removal function.
Description
Technical field
The utility model belongs to boiler afterheat and utilizes technical field, the device that specifically relates to a kind of recovery boiler flue gas heat energy and carry out dedusting.
Background technology
Be effective use of energy sources and minimizing environmental pollution, high-temperature flue gas to the boiler generation, it is people's extensive concern and the problem being devoted to solve in recent years that dirt falls in heat energy recycle and dedusting, the existing method of generally using is between boiler and chimney heat-exchanger rig to be set, existing heat-exchanger rig exists several respects shortcoming: the one, and the thermal efficiency is lower, and heat energy is not utilized effectively in the flue gas; The 2nd, corrosion-resistant, service life is short; The 3rd, function singleness, dust removing effects is poor.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of heat recovery rate height, and long service life has the device of waste heat recovery and dedusting function concurrently.
For solving the problems of the technologies described above, the utility model comprises water storage tank and the heat exchanger that is located at wherein, water storage tank is provided with gas approach, exhanst gas outlet, water inlet pipe, outlet pipe and blast pipe, gas approach and exhanst gas outlet are connected by heat exchanger, its design feature is that heat exchanger is by the air inlet connecting box, the gas outlet connecting box, heat exchanger tube and buffering flow tank are formed, air inlet connecting box and gas outlet connecting box are located at water storage tank top, and join with gas approach and exhanst gas outlet respectively, the buffering flow tank is located at the water storage tank bottom, its bottom is provided with the dedusting mouth, and air inlet connecting box and gas outlet connecting box are connected with the buffering flow tank by heat exchanger tube.
Be provided with two groups of heat exchanger tubes between air inlet connecting box, gas outlet connecting box and buffering flow tank, heat exchanger tube is provided with conducting strip outward.
The beneficial effects of the utility model are: owing to be provided with in water storage tank by the air inlet connecting box, the gas outlet connecting box, the heat exchanger that heat exchanger tube and buffering flow tank are formed, during the heat exchanger tube of high-temperature flue gas by heat exchanger most of heat is discharged in the water of water storage tank, the heat recovery rate height, heat exchanger is under water, temperature is relatively low, not fragile, long service life, the heat exchanger tube inwall is convenient to clean in space in air inlet connecting box and the gas outlet connecting box, prevented that effectively heat exchanger tube from blocking with not smooth, water tank bottom is provided with the buffering flow tank, behind the flue gas cool-down, dust energy rapid subsidence, and can remove from the dedusting mouth of its bottom.
