Abstract
A flash evaporator for improving waste gas utilization efficiency in cement industry is characterized in that the flash evaporator comprises a tank body, a hot water inlet arranged on the tank body, a vapor outlet, a hot water outlet, a long-transmitting pressure gauge connector, a safety valve connector, a liquid level meter connector, a pressure gauge connector, a manhole, a steam exhaust port and an evacuation port. Under-saturated water under certain pressure is supplied into the flash evaporator in the system for enlarging the capacitance and reducing the pressure, and due to energy conservation, high-pressure hot water in the low pressure can flash off a large amount of secondary low-pressure saturated steam which enters into a multi-parameter turbine as gas compensation after steam-water separation. The flash evaporator can stable a generating system and improve generating capability.
Description
Technical field
The utility model relates to the flasher in a kind of cement afterheat generation, especially can improve the flash vessel of exhaust gas utilization efficient.
Background technology
As everyone knows, energy savings is a set longtime policy of China, and wherein afterheat utilization is the most actively and effectively means, in many fields of the existing industry of China, afterheat utilization in the production process is all drawn attention.A large amount of novel process equipment and production line have been dropped in the cement industry transformation in recent years, supporting pure middle and low temperature cement afterheat generation system.In practical application, because technical process, the parameter major part of technology waste heat flue gas is to be in fluctuation status.And but fluctuating range often exceeds the self-regulation scope of conventional afterheat generating system design, makes the afterheat generating system can not stable operation.The fluctuating range that has even big to making compelled off-the-line of common afterheat generating system and blowing out, the economic benefit of waste heat recovery can't guarantee.Conventional single compression technology system is not owing to have flash vessel and loop, and the exhaust-heat boiler flue gas outlet temperature is not fully utilized for the low grade residual heat flue gas heat of mainly being made up of hot-air generally more than 170 ℃, and system's generating efficiency is lower.And when stove waste heat supply temperature and flow increase suddenly, have no the heat that mode can absorbing redundant, and the feed-water heater that is arranged in afterbody can be vaporized, and boiler drum level is uncontrollable, influences the normal operation of electricity generation system.
Summary of the invention
In order to reduce the waste of thermal source; Make the stable operation of afterheat generating system ability; The utility model has designed a kind of flash vessel that the cement afterheat generation industry improves exhaust gas utilization efficient that is used for; This device can make full use of thermal source, and can adapt to and regulate fluctuating widely of flue gas, makes the operation of afterheat generating system normal and stable.
The utility model solves the technical scheme that its technical problem adopted: the flash vessel of the utility model comprises tank body, is arranged on hot water inlet, steam (vapor) outlet, hot water outlet, teletransmission pressure gauge connection, relief valve connection, interface of the level gauge, pressure gauge connection, manhole, steam drain, discharging hole on the tank body.This flash vessel adopts stand-type cylinder pot type structure; Hot water inlet is located at tank body one middle side part, gos deep into tank interior with cylindrical pipe, and equidistant from distance is offered four discharge openings in the pipeline bottom; Manhole then is located at the middle and upper part of opposite side; Tank body center of top position has relief valve connection, and relief valve connection one side is a steam (vapor) outlet, and opposite side is an exhaust outlet; Tank base has hot water outlet and discharging hole; With the manhole place at grade and belong to diametric angle with manhole and become a side of 45 degree to be provided with the teletransmission pressure gauge connection, become at grade and with hot water inlet the opposite side of 30 degree angles to be provided with pressure gauge connection with the manhole place, be provided with two interface of the level gauge in the middle and lower part of tube wall with manhole opposite side in angle of 45 degrees.
The flash vessel operation principle of the utility model is: the undersaturation water under the certain pressure is sent into the flash vessel in the system; Carry out the dilatation step-down; Because the conservation of energy, high-pressure water heating under low pressure can flash off a large amount of secondary low-voltage saturated vapors, separates the back gets into multi-parameter as tonifying Qi steam turbine through carbonated drink; The stable electric generation system improves generating capacity.After introducing flash system, on the basis of conventional power generation usage technology, increase flash distillation and regulated indirect steam entering steam turbine power generation, improved the generated output of waste heat system.Adopt the multiple electricity about 10% of the general comparable routine techniques of this technology, also reduced the outlet temperature of boiler waste gas simultaneously, can be reduced to below 90 ℃.
The beneficial effect of the utility model is to improve the utilization ratio of cement kiln flue gas, the fluctuation of active adjustment flue gas, the operation of assurance afterheat generating system normal and stable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 2 is the flash vessel vertical view.
1. hot water inlets among the figure, 2. steam (vapor) outlet, 3. hot water outlet, 4. teletransmission pressure gauge connection, 5. relief valve connection, 6.a, b interface of the level gauge, 7. pressure gauge connection, 8. steam drain, 9. manhole, 10. discharging hole.
The specific embodiment
In Fig. 1 and Fig. 2; The described flash vessel of the utility model is made up of hot water inlet 1, steam (vapor) outlet 2, hot water outlet 3, teletransmission pressure gauge connection 4, relief valve connection 5, interface of the level gauge 6a, b, pressure gauge connection 7, steam drain 8, manhole 9, discharging hole 10.This flash vessel adopts stand-type cylinder pot type structure; Hot water inlet 1 is located at tank body one middle side part, gos deep into tank interior with cylindrical pipe, and equidistant from distance is offered four discharge openings in the pipeline bottom; 9 middle and upper parts that are located at opposite side of manhole; Tank body center of top position has relief valve connection 5, and relief valve connection 5 one sides are steam (vapor) outlets 2, and opposite side is an exhaust outlet 8; Tank base has hot water outlet 3 and discharging hole 10; Become a side of 45 degree to be provided with teletransmission pressure gauge connection 4 at grade and with the diametric angle in manhole 9 places with manhole 9 places, be provided with pressure gauge connection 7 at grade and with the opposite side of 1 one-tenth 30 degree of hot water inlet angle, be provided with two interface of the level gauge 6 in the middle and lower part of tube wall with manhole 9 opposite side in angle of 45 degrees with manhole 9 places.
During work; Feedwater is after feed pump gets into waste heat boiler; The hot water that produces satisfies the main feedwater of waste heat boiler and the water consumption of flash vessel simultaneously, and a part of hot water that gets into waste gas residual heat boiler generates superheated steam after the waste gas heat exchange, insert the main air intake of steam turbine.Another part HTHP undersaturation hot water gets into flash vessel, produces a certain amount of low-pressure saturated steam, gets into the low pressure filling mouth of steam turbine, and main steam and low-pressure steam do work in steam turbine, and pushing turbine rotates, and produces electric energy jointly.Flash vessel separates a large amount of saturation waters that produce and gets into oxygen-eliminating device, after deoxygenation, supplies with boiler by feed pump with the condensed water that steam turbine is discharged, and forms a complete thermodynamic cycle.
