Abstract
The utility model relates to a boiler waste gas recycling device which is characterized by mainly comprising a boiler, a waste gas recovery tank, a sedimentation tank, a water pump and a softened water storage tank. The connecting mode of the device is as follows: a gas inlet of the waste gas recovery tank is connected with a blow-off port of a boiler by a pipeline, a water outlet of the waste gas recovery tank is connected with a water inlet of the softened water storage tank by the sedimentation tank, a gas outlet of the waste gas recovery tank is connected with a gas inlet of the softened water storage tank, and a water outlet of the softened water storage tank is connected with a water supplementing port of the boiler by the water pump. The boiler waste gas recycling device has the following benefits: the structure is simple, the utilization ratio of the waste gas is high, the energy is saved, the manufacturing cost is low, and the operation is convenient.
Description
Technical field
The utility model relates to a kind of Industrial Boiler, especially relates to a kind of boiler waste gas recycle device.
Background technology
Boiler is in operation, because quality problem constantly produces calcium chloride and calcium carbonate, the continuous evaporation and concentration of high temperature saliferous demineralized water in the drum for making boiler water requirement up to specification, needs boiler water is carried out blowdown.Continuous blowdown is the highest position of salt concentration from steam-generating circuit, continuous uninterrupted is got rid of a certain amount of condensed water, and import the new demineralized water of equivalent simultaneously, to reduce stove water salt content and basicity, concentrate discharging short tens assign to time of twenties minutes several ten thousand heats that snap into the hundreds of thousands kilocalorie greatly that come down in torrents, helpless, a lot of enterprises have to directly be discharged into these high-temperature water in the trench and go, and cause the waste of a large amount of heat energy and water resource.The heat energy recycle problem of boiler operatiopn sewer is never solved for a long time effectively.
The utility model content
In order to overcome the deficiency that prior art exists, the purpose of this utility model is to provide a kind of a kind of boiler waste gas recycle device that waste-gas heat is made full use of recovery.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of boiler waste gas recycle device, this device mainly comprises boiler, waste gas recycling can, sedimentation basin, water pump, demineralized water cistern, its connected mode is: waste gas recycling can air inlet is connected with the boiler blow-off mouth by pipeline, waste gas recycling can delivery port is connected with demineralized water cistern water inlet through sedimentation basin, waste gas recycling can exhaust outlet is connected with demineralized water cistern air inlet, and the delivery port of demineralized water cistern is connected with the water supplement port of boiler through water pump.
Beneficial effect is: simple in structure, exhaust gas utilization rate height is saved the energy, and low cost of manufacture is easy to operate.

The specific embodiment
Boiler waste gas recycle device as shown in Figure 1, this device mainly comprises boiler 1, waste gas recycling can 2, sedimentation basin 10, water pump 4, demineralized water cistern 3, its connected mode is: waste gas recycling can air inlet 12 is connected with boiler blow-off mouth 6 by pipeline, waste gas recycling can delivery port 13 is connected with demineralized water cistern water inlet 9 through sedimentation basin 10, waste gas recycling can exhaust outlet 5 is connected with demineralized water cistern air inlet 11, and demineralized water cistern delivery port 8 is connected with the water supplement port 7 of boiler through water pump 4.
Its course of work is: during boiler blow-off, waste gas enters into waste gas recycling can 2 by boiler blow-off mouth 6 through waste gas recycling can air inlet 12, separation by waste gas recycling can 2, sewage and a spot of waste gas then enter into sedimentation basin 10, at this moment, add a certain amount of softening agent,, flow in the demineralized water cistern 3 by pipeline again calcium chloride in the waste gas and precipitation of calcium carbonate; Steam is then directly delivered in the demineralized water cistern by waste gas recycling can exhaust outlet 5, the bled steam that has high temperature can be heated the demineralized water in the demineralized water cistern 3, generally can reach about 50 degrees centigrade, to soften the demineralized water of having heated in the cistern 3 with water pump 4 and come to be at any time boiler replenishing water, save the energy greatly.
