Abstract

The utility model discloses a device for heating feed tar by means of pitch production waste heat, comprising a heat conducting oil storage tank, a heat conducting oil pump and a feed tar storage tank, wherein the output end of the heat conducting oil is connected to the cold medium inlet of a pitch heat exchanger through a corresponding pipeline; and a cold medium outlet is connected to the feed tar storage tank through an output pipe. Compared with the heat conducting oil furnace used for heating the feed tar in the prior art, as the heat conducting oil furnace is not arranged any more, the device is simplified and the operation is more convenient; as the waste heat generated in the pitch production is taken as a heat source, the energy source is saved and the production cost is reduced; and simultaneously, for the pitch production, oil gas volatilization is reduced; therefore, the pollution is overcome; and the pitch discharging time is shortened. The device can be widely applied to coal tar production enterprises.

Description

Utilize pitch to produce the device of waste heat to the raw tar heating

Technical field

The utility model relates to a kind of improvement of giving the raw tar heating unit, and specifically a kind of ability save energy, the pitch that utilizes that reduces production costs are produced the device of waste heat to the raw tar heating.

Background technology

At present; Device to the raw tar heating; The pipeline that comprises thermal oil storage tank, Heat-transfer Oil Pump, heat-conducting oil furnace, raw tar storage tank and be connected constitutes, and the thermal oil in the thermal oil storage tank is sent in the heat-conducting oil furnace through the Heat-transfer Oil Pump on the pipeline, through behind the heat-conducting oil furnace internal heating; Become high temperature heat conductive oil, again through pipeline input raw tar storage tank heating raw tar.Described heat-conducting oil furnace heats through coal gas.The deficiency of the heating unit of this raw tar is: because heat-conducting oil furnace so energy consumption is serious, has improved the production cost of raw tar through the coal gas heating.What also have changes heat-conducting oil furnace into steam heating through the coal gas heating, yet adopts steam heating, and the waste gas control problem that exists heat supply waste water, waste residue and coal combustion to produce again causes certain pollution to environment.In Tar production enterprise, generally also has the production project of asphalt product, used production unit in asphalt product is produced; Comprise pitch reaction kettle, asphalt exchanger, the temperature of reaction of pitch in the pitch reaction kettle is about 350 ℃, in pipeline input asphalt exchanger; Carry out heat exchange with the cold medium in the asphalt exchanger; Make it be cooled to 180 ℃, just can make pitch cooling become product, effusive cold medium temperature can reach 100 ℃ in the asphalt exchanger.Be close with the temperature required of raw tar, this is just for adopting the heat of reaction heating raw tar in the pitch reaction kettle that possibility is provided.

Summary of the invention

The purpose of the utility model is to provide a kind of thermal source that utilizes the waste heat of pitch in producing as heating raw tar; To reach save energy, to reduce production costs, the pitch that utilizes of pollution-free again, no waste water, no waste residue is produced the device of waste heat to the raw tar heating simultaneously.

For reaching above purpose; The technical scheme that the utility model adopted is: this utilizes pitch to produce the device of waste heat to the raw tar heating; Comprise that thermal oil storage tank, Heat-transfer Oil Pump and raw tar storage tank constitute; The thermal oil storage tank is connected through pipeline with Heat-transfer Oil Pump, in the thermal oil storage tank, fills thermal oil, it is characterized in that: the thermal oil delivery side of pump is connected with the cold medium admission port of asphalt exchanger through corresponding pipeline; Cold medium delivery port inserts the raw tar storage tank through output tube; Establish the import of pitch heat material in an end bottom of asphalt exchanger, the pitch heat of asphalt exchanger expects that import connects the pitch reaction kettle through the pitch output channel, is establishing the outlet after pitch heat material is lowered the temperature with the relative end of pitch heat material import on the asphalt exchanger.

The utility model is also implemented through following measure: described asphalt exchanger is a tubular heat exchanger; Outlet, cold medium admission port, the tube bank of cold medium, cold medium delivery port, left and right sealing baffle, left and right end cap and traverse baffle by after tubular shell, the import of pitch heat material, the cooling of pitch heat material constitute; The import of pitch heat material is located at the right-hand member of tubular shell bottom; Outlet after the cooling of pitch heat material is located at the left end of tubular shell bottom; Cold medium admission port is located at the bottom of left end cap, and cold medium delivery port is located at the top of right end cap, makes flow direction and the heated bitumen of cold medium in cold medium tube bank opposite at the intravital flow direction of shell; Consider that simultaneously pitch heat material cooling back denseness strengthens, so the outlet after the cooling of pitch heat material is located at the bottom.

The beneficial effect of the utility model is: compare with present employing heat-conducting oil furnace heating raw tar, owing to no longer establish heat-conducting oil furnace, so simplified equipment, make it more convenient to operate; Owing to adopted the waste heat of pitch in producing, so practiced thrift the energy, reduced production cost as thermal source; Simultaneously, produce, reduced the volatilization of oil gas, overcome pollution, shortened the pitch blowing time for pitch.Can be widely used in coal tar manufacturing enterprise.
