Technical field
The invention belongs to blast furnace slag quenching water waste heat recovery field, be related specifically to steel plant's using exhaust heat of slag flushing water and reclaim special equipment.
Background technology
In recent years, China's steel industry is in the high speed development stage.China's steel industry energy structure is based on coal, and main energy structure is towards multiplex coal, few electricity consumption and the future development without oil and natural gas, this energy resource structure objectively causes the present situation that China's steel and iron industry efficiency of energy utilization is low, seriously polluted and energy-saving and emission-reduction task is heavy.In the last few years, along with the development of power-saving technology, China's steel industry industrial afterheat recovery utilizes level to be greatly improved, but still has very large gap compared with international most advanced level.The rate of recovery of the residual heat resources such as waste heat, complementary energy (comprising by-product gas) of external advanced iron and steel enterprise is generally more than 90%, and China compares backward 20% with Foreign Advanced Lerel.Trace it to its cause, domestic iron and steel enterprises is difficult to accomplish effectively to reclaim the lower residual heat resources of taste.Mainly not overripened because be limited by low grade residual heat recovery technology, be difficult to accomplish, under the prerequisite of safe and reliable operation, effectively to reclaim low grade residual heat.And in the production process of steel industry, high temperature furnace slag is all generally the mode cooling down high-temperature slags by Water Quenching Slag, the heat loss that high temperature furnace slag contains by the mode eventually through cooling water is in air.According to preliminary understanding, the heat that slag contains is about 0.74GJ/t, if according to 2007 the whole nation output of steel 48924.08 ten thousand tons calculating, then the available heat of slag is about 12570MW.
Owing to containing a large amount of solid particles and suspension in washing slag water, be directly used in heating, the blockings such as the pipeline in heating system, valve, radiator can be made, so washing slag water can not be directly used in heating.The heat energy of blast furnace slag quenching water cannot be utilized.
Summary of the invention
The object of the invention is in order to overcome a large amount of particle that washing slag water contains and suspension bring heating system to block deficiency, a kind of detachable heat exchanger for blast furnace slag quenching water of proposition.This heat exchanger not only can reclaim the heat in washing slag water, the phenomenon of the washing slag water heat exchanger blocking that a large amount of particle and high suspended matter can also be avoided to bring.
A kind of detachable heat exchanger for blast furnace slag quenching water that the present invention proposes, it is characterized in that, comprise housing, what be arranged on that housing two ends are connected respectively by flange enters water tank and water tank, the washing slag water inlet tube that the other end of the other end and water tank that enter water tank is connected respectively and washing slag water outlet; Be arranged on the deflection plate in housing, two ends respectively with the heat exchanger tube entering water tank and be communicated with water tank, also comprise the detachable spoiler be placed in heat exchanger tube; Be communicated with hot water backwater inlet tube at housing upper, be communicated with hot water backwater's outlet in lower housing portion, entering water tank and water tank bottom has sewage draining exit, washing slag water inlet tube and outlet bobbin carriage have sewage draining exit, hot water outlet.
Feature of the present invention and useful achievement:
The present invention proposes a kind of detachable washing slag water heat exchanger, the heat exchanger of this equipment routine improves, the heat reclaiming and contain in washing slag water can be directly used in, and fundamentally solve washing slag water contain the problem of the usual heat exchanger blocking that a large amount of particles and suspension cause, fundamentally improve the utilization ratio of primary energy, save the energy, emissions reduction, reduce the use cost of user.

Detailed description of the invention
A kind of washing slag water dedicated heat exchanger drawings and the embodiments that the present invention proposes are described in detail as follows:
Structure of the present invention is as shown in Figure 1: the detachable washing slag water heat exchanger of one that the present invention proposes, and comprises washing slag water inlet tube 1, washing slag water outlet 2, hot water outlet pipe 3, hot water inlet's pipe 4, enters water tank 5-1 and water tank 5-2, blow-off pipe 6-1 and 6-2, adpting flange 7-1 and 7-2, housing 8, multiple deflection plate 9, many heat exchanger tubes 10; Also comprise the detachable spoiler 11 be placed in heat exchanger tube; Wherein, washing slag water inlet tube 1 by the mode of welding with enter water tank 5-1 and be connected, enter water tank and be connected with housing 8 by adpting flange, housing 8 is connected with water tank 5-2 by adpting flange, and the mode that water tank 5-2 passes through to weld is connected with washing slag water outlet; Hot water inlet's pipe 3 is connected with housing 8 by the mode of welding, and housing 8 is connected with hot water outlet pipe 4 by the mode of welding; Many heat exchanger tube 10 two ends by the mode of expand tube respectively with enter water tank and water tank is connected; Sewage draining exit pipe by the mode of welding respectively with enter water tank and water outlet place is connected; Multiple deflection plate 9 is connected with housing 8 inwall by the mode of welding.
The course of work of the present invention is: washing slag water enters water tank 5-1 from washing slag water inlet tube 1, heat exchanger tube 10 is entered by water cartonning 5-1, flow-disturbing fluidised form is there is by the effect of spoiler 11 in heat exchanger tube, enhanced heat exchange effect, inside pipe wall is washed away simultaneously, prevent solid particulate matter in washing slag water and sedimentation of suspension to inner-walls of duct.Meanwhile, hot water backwater enters in housing and carries out heat exchange by pipe wall of heat exchange pipe and washing slag water, reclaims the heat in washing slag water.
