Abstract
The utility model relates to a drying chamber waste gas waste heat utilization equipment constitutes by drying chamber TNV heating device (1) subtotal lithium bromide refrigeration unit (3) is partial, its characterized in that is in two parts between increase waste heat utilization equipment (2), connect gas~water heat transfer device (4) at drying chamber TNV heating device's (1) back end promptly, all pass through the pipe connection between the three. The utility model discloses a superior part lies in that the device effectively utilizes waste gas and burns the back waste heat, has practiced thrift the energy, the automobile coating production line just burst at the seams or the condition of the shortage of heat that the drying chamber provided under to guarantee entire system's normal operation.
Description
Technical field
The utility model relates to coating process technical field, is specifically related to the drying chamber TNV system residual heat using device of paint line.
Background technology
In the drying plant of automobile coating production line, the most frequently used heating system is TNV heating system at present. This system is generally made up of direct-fired burned waste gas heating plant, multiple smoke heat replacing device, rear class new air heat-exchange device, waste gas air-introduced machine, electric-control system etc., waste gas air-introduced machine is sent into the waste gas in drying chamber in direct-fired burned waste gas heating plant and is carried out burning disposal, waste gas directly contacts with flame, combustible component combustion decomposition in waste gas is become to carbon dioxide and the water vapour of nontoxic odorless. Waste gas after burning is supplied with heat by smoke heat replacing device to each functional section of drying chamber, carries out temperature control by electric control valve; Through one-level fresh air heat exchanger, the new wind filling in stove is carried out to preheating again, the temperature in drying chamber is maintained within the scope of process requirements.
Because this system is to design and configure according to the maximum production capacity of workpiece, exhaust-gas treatment amount is also calculated by this design input, and therefore the normal operating conditions of this system is carried out work by maximum heat demand amount. Because actual body quality does not reach design maximum quality, equipment capacity neither be in the state of producing at full capacity always simultaneously, and heat demand is not maximum heating load. Therefore this system has waste heat greatly by toxic emission to atmosphere, to have caused the waste of the energy.
Utility model content
The object of the utility model is to overcome the defect existing in prior art, and a kind of drying room waste gases residual heat using device is provided.
For realizing described object, the utility model has adopted following technical scheme. Drying room waste gases residual heat using device, formed by drying chamber TNV heating plant and lithium bromide refrigerating unit, between described two parts, increase residual heat using device, connect gas～water heat-exchanger rig at the back segment of drying chamber TNV heating plant, between three, all connect by pipeline.
A hot water storgae is set in above-mentioned residual heat using device again, assisted heating device is set in groove, between hot water storgae and lithium bromide refrigerating unit, be connected hot water circulating pump.
Superior part of the present utility model is that this device effectively utilizes waste heat after burned waste gas, has saved the energy, in the case of the shortage of heat that automobile coating production line has just burst at the seams or drying chamber provides, to ensure the normal operation of whole system.
Brief description of the drawings
Accompanying drawing is the new structural representation of this practicality.
Detailed description of the invention
A kind of drying room waste gases residual heat using device, refer to accompanying drawing, formed by drying chamber TNV heating plant 1 part and lithium bromide refrigerating unit 3 parts, between described two parts, increase residual heat using device 2, connect gas～water heat-exchanger rig 4 at the back segment of drying chamber TNV heat supply part 1, between three, all connect by pipeline. A hot water storgae 5 is set in residual heat using device 2 again, assisted heating device is set in groove, between hot water storgae 5 and lithium bromide refrigerating unit part 3, be connected hot water circulating pump.
The operation principle of this device is the newly-increased a set of gas～water heat-exchanger rig 4 of back segment in original drying chamber TNV heat supply part 1, the waste heat of drying room waste gases is converted to the heat of hot water, and the toxic emission temperature of drying chamber is controlled in a rational scope. The hot water of multiple drying chamber outputs of automobile coating production line is aggregated in a hot water storgae 5 simultaneously, the energy by hot water circulating pump using interior hot water storgae 5 hot water supply lithium bromide refrigerating unit 3 as its operation, the cold water of finally making by refrigeration unit is as the required refrigerant of Painting Shop miscellaneous equipment. Simultaneously in order to ensure lithium bromide refrigerating unit 3 hot water temperatures' demand, need a set of gas auxiliary heating device be set hot water storgae 5 is interior, object is in the case of the shortage of heat that automobile coating production line has just burst at the seams or drying chamber provides, recirculated water to hot water storgae heats, to ensure the normal operation of whole system.
Claims (2)
1. a drying room waste gases residual heat using device, formed by drying chamber TNV heating plant (1) part and lithium bromide refrigerating unit (3) part, it is characterized in that increasing residual heat using device (2) between described two parts, connect gas～water heat-exchanger rig (4) at the back segment of drying chamber TNV heating plant (1), between three, all connect by pipeline.
2. a kind of drying room waste gases residual heat using device as claimed in claim 1, it is characterized in that arranging again a hot water storgae (5) in residual heat using device (2), assisted heating device is set in groove, between hot water storgae and lithium bromide refrigerating unit (3), is connected hot water circulating pump.
