Abstract
The utility model discloses a coal-burning steam boiler discharge sewage reuse device, which comprises a boiler main body (1), a flue (2), a sewage discharge pipe (3), a water film deduster cyclically used water basin (4), a water film deduster (5), a water film deduster water inlet pipe (6), a water film deduster water outlet pipe (7) and a water circulating pump (8). According to the utility model, the sewage discharge pipe (3) is arranged to be directly connected to the water film deduster cyclically used water basin (4), and alkaline sewage generated by the coal-burning steam boiler is directly discharged into the water film deduster cyclically used water basin (4), and neutralizes the acid water in the water film deduster cyclically used water basin (4), thus reducing the amount of alkali and reducing the production cost.
Description
Technical field
The utility model relates to coal-fired steam boiler, is directly involved in a kind of coal-fired steam boiler sewer re-use device.
Background technology
Present stage, the sewer of coal-fired steam boiler account for greatly boiler duty 5%～8% between, the pH value is between 10～12, and the consumption of boiler water film dust-remover cycling use of water is by 15 tons of boiler calculations, greatly about about 6m3, and it is acid that the water dust scrubber water outlet is, and need add alkali and carry out water quality neutralization and desulfurization, increases production cost.
Summary of the invention
The purpose of this utility model just provides a kind of coal-fired steam boiler sewer re-use device, it can make boiler blowdown water directly enter water dust scrubber cycling use of water pond, the water dust scrubber cycling use of water is neutralized, can reduce the consumption of alkali number, thereby reach the purpose of energy-saving and emission-reduction.
The purpose of this utility model is to realize like this, a kind of coal-fired steam boiler sewer re-use device, have coal-fired steam boiler, flue, blow-off pipe, water dust scrubber cycling use of water pond, water dust scrubber, water dust scrubber water inlet pipe, water dust scrubber rising pipe and water circulating pump, described blow-off pipe is connected between coal-fired steam boiler main body and the water dust scrubber cycling use of water pond, and water dust scrubber enters water dust scrubber cycling use of water pond with the recirculated water of crossing through the water dust scrubber rising pipe.
The utility model directly is connected on the water dust scrubber cycling use of water pond owing to blow-off pipe being set, the alkaline sewage that coal-fired steam boiler is produced directly is drained into water dust scrubber cycling use of water pond, sour water in the water dust scrubber cycling use of water pond is neutralized, reduce alkali charge, reduce production costs.
Description of drawingsAccompanying drawing 1 is the schematic diagram of a kind of coal-fired steam boiler sewer of the utility model re-use device, below in conjunction with accompanying drawing, the utility model is further specified.
EmbodimentAccompanying drawing shows a kind of coal-fired steam boiler sewer of the utility model re-use device, by coal-fired steam boiler 1, flue 2, blow-off pipe 3, water dust scrubber cycling use of water pond 4, water dust scrubber 5, water dust scrubber water inlet pipe 6 and water dust scrubber rising pipe 7, water circulating pump 8 forms, the flue gas that coal-fired steam boiler 1 produces enters water dust scrubber 5 by flue 2, the sewage that coal-fired steam boiler 1 produces enters water dust scrubber cycling use of water pond 4 by blow-off pipe 3, the recirculated water that water dust scrubber 5 usefulness are crossed enters water dust scrubber cycling use of water pond 4 through water dust scrubber rising pipe 7
Claims (1)
1. coal-fired steam boiler sewer re-use device, has boiler body (1), flue (2), blow-off pipe (3), water dust scrubber cycling use of water pond (4), water dust scrubber (5), water dust scrubber water inlet pipe (6), water dust scrubber rising pipe (7) and water circulating pump (8), it is characterized in that described blow-off pipe (3) is connected between coal-fired steam boiler main body (1) and the water dust scrubber cycling use of water pond (4), water dust scrubber enters water dust scrubber cycling use of water pond (4) with the recirculated water of crossing through water dust scrubber rising pipe (7).
