Description
Technical field
The invention belongs to energy-conservation, purification techniques field, relate in particular to a kind of energy-conservation, as to purify integrated design dryer that has.
Background technology
At present, dryer is the main energy consumption equipment of textile printing and dyeing industry, difference according to bake out temperature and discharge amount of exhaust gas, every dryer approximately have 30-50 ten thousand kilocalories/hour heat waste because of toxic emission, under the macroscopic of energy-saving and emission-reduction, at the Waste gas outlet of dryer energy-saving heat exchanger is installed and is of great practical significance.
The general employing of heat exchanger of installing on the dryer at present directly is installed on the waste gas outlet top of machine, adopt waste gas from bottom to top, the new top-down arrangement of wind.There are three large disadvantages in this design: first makes heat exchanger heat pipe layout angle very little owing to being subject to waste gas outlet pipeline limitation in height, thereby greatly reduces the heat-transfer effect of heat pipe; Second since waste gas circulation arrange by general layout from bottom to top because the factors such as manufacturing, design easily make oily matter in the waste gas because cooling becomes fluid drips in the baking oven on the fabric (filter screen), result in blockage and pollute; The 3rd, heat exchanger is poorly sealed when installing affects heat transfer effect and causes oil dripping because the factors such as dryer top structure easily cause.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of dryer, the heat exchanger of its installation adopts waste gas and new wind side direction, contrary formula turnover, adopts bottom oil collecting pot oil-collecting, thereby improves the heat exchange energy-saving effect, reduces and pollutes.
To achieve the above object, the present invention has adopted following technical scheme:
A kind of dryer comprises drying machine body and heat exchanger, and the inner space of described heat exchanger is divided into former and later two relatively independent spaces by dividing plate, and a space is exhaust steam passage, and another space is new wind passage; The left side of exhaust steam passage is provided with filter screen A and exhaust gas inlet tube connector, and the right side of exhaust steam passage is provided with the waste gas outlet tube connector, is provided with a plurality of heat pipes in the exhaust steam passage, and heat pipe passes dividing plate and enters in the new wind passage; The right side of new wind passage is provided with fresh inlet tube connector, filter screen B and damper, and the left side of new wind passage is provided with new wind outlet connecting pipe, in the new wind passage described heat pipe is set; Described heat pipe is the straight tube that inner sealing has thermal medium, and a plurality of heat pipes are arranged with array way by rest stand and dividing plate and are installed in heat exchanger inside, and described heat exchanger inside is provided with oil collecting pot; Described a plurality of heat pipe axis is obliquely installed horizontal by 35 °～45 °, and the end that heat pipe is positioned at exhaust steam passage is lower than the end that it is positioned at new wind passage; Described exhaust gas inlet tube connector is connected with exhaust outlet on the drying machine body, and described new wind outlet connecting pipe is connected with air inlet on the drying machine body.
The present invention is owing to having adopted above technical scheme, and the heat exchanger of its installation adopts waste gas and new wind side direction, contrary formula turnover, adopts bottom oil collecting pot oil-collecting, thereby improves the heat exchange energy-saving effect, reduces and pollutes.Owing to adopting the fluid side turnover, when arranging, heat pipe is not subjected to the exhaust piping limitation in height, the heat pipe layout angle can be greater than 15 ° of angles, and conventional fluid pass in and out up and down can only be less than 5 ° of angles, the raising at angle of inclination can improve the heat-transfer effect of gravity type heat pipe greatly, through repeatedly experimental verification, when the heat pipe axis tilts horizontal by 35 °～45 °, has best heat-transfer effect with respect to other angles of inclination; Because fluid employing side direction passes in and out, will do not collected by the bottom oil collecting pot because of gravity because of the oils liquid of temperature drop or other factors generation and can splash into dryer inside in addition; The 3rd, be connected the airduct that relies on the side direction turnover between heat exchanger and the dryer, so need not to worry the sealing problem of dryer top between bottom heat exchanger.
