Abstract
The utility model relates to a lime kiln waste gas waste heat recovery system which comprises a lime kiln, a main flue, a bypass flue, a heat pipe heat exchanger, a primary dust remover and an induced draft fan. The flue gas exhaust end of the lime kiln is connected with the main flue which is connected with the bypass flue in parallel, the bypass flue is provided with the heat pipe heat exchanger, the primary dust remover is installed on a bypass pipeline at the front end of a flue gas inlet of the heat pipe heat exchanger, and the induced draft fan is installed on a bypass pipeline at the rear end of a flue gas exhaust port of the heat pipe heat exchanger. The heat pipe heat exchanger is installed in the bypass flue, so normal operation of the lime kiln cannot be influenced by faults of the heat pipe heat exchanger; the primary dust remover is installed at the flue gas inlet of the heat pipe heat exchanger, so that a great amount of dust is prevented from directly entering the heat pipe heat exchanger and influencing the service life of the heat pipe heat exchanger. The lime kiln waste gas waste heat recovery system is reasonable in structure and high in recovery efficiency, the temperature of waste gas is greatly lowered, heat of high-temperature flue gas is conveyed outside in a steam mode, and therefore the waste gas can be exhausted at the normal temperature, and the aims of energy conservation and emission reduction are achieved.
Description
Technical field
The utility model belongs to heat recovery technology field, specifically, is a kind of limekiln exhaust gas residual neat recovering system.
Background technology
At present, being widely used of limekiln, can see its use in each large cement building trade, the kiln exit gas discharge in limekiln becomes the emphasis of numerous producers research, in order to improve limekiln flue gas waste heat recovery, and can save production cost, conventionally mounting heat exchanger in flue collector.
But the problem that the mounting means of above-mentioned heat exchanger exists is: 1, once heat exchanger breaks down, directly affect the normal production in whole limekiln; 2, because limekiln produces a large amount of dusts, with the high-temperature flue gas of dust, directly enter in heat exchanger and carry out heat exchange, have a strong impact on the service life of heat exchanger, improve to have tieed up and accomplish this.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, improve the heat exchanger limekiln exhaust gas residual neat recovering system in service life.
Technical solutions of the utility model are achieved in that
A kind of limekiln exhaust gas residual neat recovering system, comprise limekiln, flue collector, bypass flue, heat exchange of heat pipe, elementary deduster and air-introduced machine, the smoke discharging end in described limekiln connects flue collector, this flue collector bypass flue in parallel, this bypass flue is installed heat exchange of heat pipe, this heat exchange of heat pipe enters on the bypass duct of mouth front end elementary deduster is installed, and on the bypass duct of the exhaust opening rear end of heat exchange of heat pipe, air-introduced machine is installed.
And, described flue collector is installed flue collector electric butterfly valve, this heat exchange of heat pipe enters on the bypass flue between mouth and elementary deduster bypass flue electric butterfly valve is installed, and on the bypass flue between described heat exchange of heat pipe exhaust opening and air-introduced machine, bypass flue electric butterfly valve is installed.
And, shock wave soot blower is installed in described heat exchange of heat pipe.
Advantage of the present utility model and good effect are:
Native system is arranged on heat exchange of heat pipe in bypass flue, can not affect because of the fault of heat exchange of heat pipe the normal work in limekiln; By the mouth that enters at heat exchange of heat pipe, elementary deduster is installed, thereby avoid a large amount of dusts directly to enter heat exchange of heat pipe, is affected its service life.The utility model is rational in infrastructure, organic efficiency is high, greatly reduces the temperature of waste gas, and the heat of high-temperature flue gas is sent outside with the form of steam, and waste gas is discharged with normal temperature, has reached the object of energy-saving and emission-reduction, reduces the injury to environment and human body.
Accompanying drawing explanation
Fig. 1 is system connection diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of limekiln exhaust gas residual neat recovering system, as shown in Figure 1, comprise limekiln 1, flue collector 2, bypass flue 4, heat exchange of heat pipe 7, elementary deduster 5 and air-introduced machine 9, the smoke discharging end in described limekiln connects flue collector, this flue collector connects bypass flue, this bypass flue is installed heat exchange of heat pipe, in order to prevent that dust from entering, in heat exchange of heat pipe, affect its work, at heat exchange of heat pipe, enter on the bypass duct of mouth front end elementary deduster is installed, in order to keep enough flue gas flow rates, on the bypass duct of the exhaust opening rear end of heat exchange of heat pipe, air-introduced machine is installed.
In the present embodiment, flue collector electric butterfly valve 3 is installed in described flue collector, this heat exchange of heat pipe enters on the bypass flue between mouth and elementary deduster bypass flue electric butterfly valve 6 is installed, and on the bypass flue between described heat exchange of heat pipe exhaust opening and air-introduced machine, bypass flue electric butterfly valve 8 is installed.
Shock wave soot blower is installed in described heat exchange of heat pipe, dust can be removed and discharged from device bottom from tube wall, prevent that occluding device from reducing the heat exchange efficiency of equipment.
Operation principle of the present utility model is:
High-temperature flue gas process bypass flue (flue collector electric butterfly valve cuts out) from 305 ℃ of left and right, limekiln, enter elementary deduster, after removing the most of dust in flue gas, enter again heat exchange of heat pipe, flue-gas temperature is dropped to 160 ℃, be incorporated to flue collector after air-introduced machine and sack cleaner, from smoke stack emission, require to consider the load of existing air-introduced machine, reduce residual neat recovering system resistance as far as possible.
Native system is arranged on heat exchange of heat pipe in bypass flue, can not affect because of the fault of heat exchange of heat pipe the normal work in limekiln; By the mouth that enters at heat exchange of heat pipe, elementary deduster is installed, thereby avoid a large amount of dusts directly to enter heat exchange of heat pipe, is affected its service life.The utility model is rational in infrastructure, organic efficiency is high, greatly reduces the temperature of waste gas, and the heat of high-temperature flue gas is sent outside with the form of steam, and waste gas is discharged with normal temperature, has reached the object of energy-saving and emission-reduction, reduces the injury to environment and human body.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
