Abstract

The utility model discloses a water heater by utilizing waste heat. A waste hot gas circulating pipe is arranged in a to-be-heated water tank of the water heater; a plurality of groups of heat exchange pipes are arranged in the waste hot gas circulating pipe; the water to be heated in the tank can flow in the heat exchange pipes and thoroughly exchange heat with the waste hot gas; and in this process, the flowing directions of the water to be heated in the tank is reverse to the flowing direction of the waste hot gas in the waste hot gas circulating pipes, so the water can be gradually heated to the desirable temperature in the flowing process. An electromagnetic valve controlled by an automatic control device to open and close is installed on the to-be-heated water injection tube of the water heater, when the water is heated to the desirable temperature, the automatic control device enables the electromagnetic valve to open and then the hot water can flow out, and otherwise, the electromagnetic valve closes. The water heater can be connected with a proper hot waste gas source in a hotel, a restaurant or an enterprise and public institution work unit and can well absorb and use the heat of the hot waste gas. Therefore, the water heater can make positive contributions in reducing cost, saving energy and increasing efficiency to the hotel, the restaurant or the enterprise and public institution work unit.

Description

Utilize the water heater of waste heat energy

Technical field

The utility model relates to water heater or hot water facility, especially utilizes the waste heat waste gas of boiler or cooking stove and other heat resource equipment to add the water heater of hot water.

Background technology

In the prior art, water heater is to use combustion gas with relevant hot water facility great majority, fuel oil, the water that coal and electricity directly heat needs heats, various pot-type boilers on the market, civil boilers etc. are this form of utilizing heat energy, but common boiler and gas heater or electric heater are in the process of direct consumes energy, the heat utilization efficiency of its energy is generally lower, the heat energy that a lot of energy burnings produce just is not utilized and is discharged, the methods and the structural design that do not have UTILIZATION OF VESIDUAL HEAT IN, in energy-intensive today is a very big waste, the contradiction of also having aggravated supply and demand and resource environment simultaneously.For making full use of energy resources, heat energy particularly, improve heat utilization efficiency, it is one of this UTILIZATION OF VESIDUAL HEAT IN form that some industrial and mining enterprises use cogeneration technology, in agricultural, also generally use waste heat to carry out kind of a breed, use waste heat booth technology that crops are carried out temperature adjusting etc., but above-mentioned technology and equipment is just prepared for the specific content of particular items, not only investment is big, the cost height, also unaccommodated in the hotel, use in places such as restaurant, and most of hotels, the restaurant, the boiler of hospital and enterprises and institutions and heat resource equipment be not owing to there is corresponding UTILIZATION OF VESIDUAL HEAT IN equipment, its heat utilization efficiency is still lower, and the waste heat that is produced has to directly discharge, thereby has strengthened entreprise cost and burden.

The utility model content

The water heater that the technical problems to be solved in the utility model is to provide a kind of waste heat waste gas that boiler, cooking stove and heat resource equipment produced that utilizes hotel, hospital and some enterprises and institutions to heat, the hot water that it produced i.e. to a certain degree the demand that satisfies these departments, has improved the heat utilization efficiency of the energy again.

It is such that the utility model solves the water heater that utilizes waste heat energy that above-mentioned heat utilization efficiency problem proposes: the waste heat waste gas that heat power supply device produced such as boiler cooking stove are imported water heater described in the utility model by carrier pipe after dedusting, this water heater comprises and is subjected to container body of hot water, waste hot air air inlet and outlet, be subjected to hot water ascending pipe and discharge pipe, it is characterized in that: be subjected to be equipped with in the container body of hot water waste hot air and follow the stream pipe, and the heat-exchange tube that in waste hot air follows the same cutting plane of stream pipe, is welded and forms a group by some, the two-port of these heat-exchange tubes connects with being subjected to the water body in the container body of hot water, heat-exchange tube has some groups in waste hot air follows the stream pipe, and arranges at a distance of certain distance.

This water heater waste hot air follows the stream pipe and places and be full of in the casing that is subjected to hot water, and in pipe, add some groups of heat-exchange tubes, the hot water that is subjected in this heat-exchange tube and the casing connects, therefore also can in this heat-exchange tube, flow by hot water, when the waste heat air-flow that is imported by air-introduced machine flows in waste hot air follows the stream pipe, waste hot air follows the stream pipe and heat-exchange tube promptly carries out heat exchange with being subjected to hot water, in this process, being subjected to hot water and waste heat air-flow is reverse flow, therefore the cold water that is injected is progressively heated and is discharged in the process that flows to the higher entrance point of temperature from the lower outlet side of waste hot air temperature, thereby reaches the purpose of utilizing waste heat.

The not only available waste hot air of the water heater that utilizes waste heat energy that the utility model proposed adds hot water, also can be exchanged under certain condition to add the part heating that hot-air or other medium are used for above-mentioned department.In addition, that the utility model also has is simple in structure, make install easily, the place take very little, to manufacturing the characteristics that material has no special requirements, be easier to apply, to energy-saving and cost-reducing, the positive effect of increasing the benefit.

The utility model is described in further detail below in conjunction with drawings and embodiments.

Description of drawings

Fig. 1 is the main cutaway view of a kind of embodiment of the utility model.

The specific embodiment

According to the water heater that utilizes waste heat energy shown in Figure 1, its shell is to be subjected to container body of hot water 1, wrap up with insulation material, waste hot air is housed in being subjected to container body of hot water 1 follows stream pipe 2, waste hot air follows stream pipe 2 and takes the shape of the letter U or S shape in Fig. 1, and can be designed to as requested by the combination of a group or some groups (to follow the stream pipe be example to adorn one group of U-shaped waste hot air in Fig. 1), in this example, waste hot air follows the cross section of stream pipe 2 for circular or square, and the heat-exchange tube 3 that in waste hot air follows the same cutting plane of stream pipe 2, is welded and forms a group by some, the two-port of these heat-exchange tubes 3 connects with being subjected to the water in the container body of hot water 1, can make like this to be subjected to hot water and waste hot air to carry out heat exchange more fully.Heat-exchange tube 3 has some groups in waste hot air follows stream pipe 2, and at a distance of the certain distance layout, be subjected to the water body in the container body of hot water 1 then to follow stream pipe 2 centre positions separately by heat insulation 4 the waste hot airs of pulling at U-shaped, this is that the water body that makes waste hot air follow the stream pipe 2 different water temperatures that heated is unlikely mixing, and offer and be subjected to flow of hot water port 10 in heat insulation 4 bottoms of pulling, its shape or for follow the annular port of stream pipe 2 outer walls around waste hot air.The position is established and is subjected to hot water discharge pipe 8 near the waste hot air air inlet 5 that is subjected on the container body of hot water 1; The position is then adorned and is subjected to hot water ascending pipe 7 near waste hot air outlet 6, in being subjected to container body of hot water 1, being subjected to hot water and waste hot air to follow stream and managing 2 interior waste heat air-flow reverse flows each other like this, is subjected to hot water progressively to be heated the back outflow in flow process thereby make.
